Considering the definition of an inequality, you get:
a. the numbers of glass bottles your class needs to collect if no plastic bottles are collected is 2000.
b. the numbers of plastic bottles your class needs to collect if no glass bottles are collected is 1000.
c. the inequality that represents how many of each type of bottle your class can collect to reach the goal is 0.05×g + 0.10s≥100.
Definition of inequalityAn inequality is the existing inequality between two algebraic expressions, connected through the signs:
greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.An inequality contains one or more unknown values called unknowns, in addition to certain known data.
Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.
Inequality in this caseIn this case, you know that:
Your class wants to raise at least $100 for a charity by collecting bottles.Each glass bottle earns $0.05. Each plastic bottle earns $0.10.Being:
"g" the numbers of glass bottles your class needs to collect."p" the numbers of plastic bottles your class needs to collect.a. the numbers of glass bottles your class needs to collect if no plastic bottles are collected is calculated as:
0.05×g≥100
Solving:
g≥100÷ 0.05
g≥2000
b. the numbers of plastic bottles your class needs to collect if no glass bottles are collected is calculated as:
0.10×s≥100
Solving:
s≥100÷ 0.10
s≥1000
c. the inequality that represents how many of each type of bottle your class can collect to reach the goal is:
0.05×g + 0.10s≥100
In summary, you get:
a. the numbers of glass bottles your class needs to collect if no plastic bottles are collected is 2000.
b. the numbers of plastic bottles your class needs to collect if no glass bottles are collected is 1000.
c. the inequality that represents how many of each type of bottle your class can collect to reach the goal is 0.05×g + 0.10s≥100.

Helen used 14 of her savings for her first year of college. 38 of that money was spent on her housing and meals. Which equation shows the fraction of her total savings that was spent on her housing and meals?
Answer: 3/32
Step-by-step explanation:
Here's the complete question:
Helen used 1/4 of her savings for her first year of college. 3/8 of that money was spent on her housing and meals. Which equation shows the fraction of her total savings that was spent on her housing and meals?
Since we are told that Helen used 1/4 of her savings for her first year of college and that 3/8 of that money was spent on her housing and meals.
To calculate the fraction of her total savings that was spent on her housing and meals, we would multiply 1/4 by 3/8. This will be:
= 1/4 × 3/8
= 3/32

Topic: Perpendicular to Chord Property
Since the diagram shows a right triangle and gives out some measurements of the sides, you can use the Pythagorean Theorem ([tex]a^{2}+b^{2}=c^{2}[/tex]) to find the length of MP.
Given:
hypotenuse = 7 – because the radius is 7 units and it can be used as the hypotenuse
One side of the triangle = 4 – because the length of PO is 4 units and it can be used as one sides of the triangle
To Solve:
Since we know two values of the triangle, you can use the Pythagorean Theorem ([tex]a^{2}+b^{2}=c^{2}[/tex]) to find what the other value is. The variables c and b in the formula are already given, and we need to find what a is to find the length of MP. So, plug the given values of c and b into the formula:
[tex]a^{2}+4^{2}=7^{2}[/tex]
Simplify:
[tex]a^{2}+16=49[/tex]
Subtract 16 from both sides of equation:
[tex]a^{2}=33[/tex]
Do the square root of both sides to isolate the variable a:
[tex]\sqrt{a^{2}}=\sqrt{33}[/tex]
Evaluate:
[tex]a=\sqrt{33}[/tex] Which simplifies to [tex]a= 5.744562646....[/tex] and round it to the nearest tenth to finally get [tex]a=5.7[/tex]
Answer: The length of MP is 5.7 units
How to solve Part AIf you look at the diagram in the question, you can see that the length of MN is twice the length of MP. So multiply the length of MP, which is 5.7, by 2:
5.7 · 2 = 11.4
Answer: The length of MN is 11.4 units

Question 2:How to solve Part ALook at the first image below ↓
Description of the first image:
The first image shows a drawn image of the circle with labeled parts and measurements from the infomation given from the question.
The diameter is 26cm, which means that the radius is 13cm because the radius half of the diameter in a circle. The very top line is the surface of the water where it’s filled and it has a length of 20cm. Side b of the triangle is 10cm becuase it’s half the length of the the surface of the water bowl. The hypotenuse (side c) is 13cm because it’s the length of the radius. And side a is what what we need to find because it’s the distance between the surface of the water and the center of the bowl. But after when you find the length of side a, you need to add the length of the radius (which is 13cm) to the length of side a because that’s the rest of the length/depth of the water that’s filled in the bowl. The length of the radius is included with the depth of the water.
Total information given:
⇒ radius = 13cm – because the radius is half of the diameter, and the diameter has a length of 26cm
⇒ length of the surface where the water’s filled = 20cm
⇒ hypotenuse (side c) = 13cm – because it’s the length of the radius
⇒ side b = 10cm – because it’s half the length of the surface where the water’s filled
To Solve
Since there is a right triangle shown in the image, you can use the Pythagorean Theorem ([tex]a^{2}+b^{2}=c^{2}[/tex]) to find the missing length of side a. Plug the given values of c and b into the formula:
[tex]a^{2}+10^{2}=13^{2}[/tex]
Simplify:
[tex]a^{2}+100=169[/tex]
Subtract 100 from both sides of the equation:
[tex]a^{2}=69[/tex]
Do the square root of both sides to isolate the variable a:
[tex]\sqrt{a^{2}}=\sqrt{69}[/tex]
Evaluate:
[tex]a=\sqrt{69}[/tex] Which simplifies to [tex]a= 8.30662386....[/tex] and round it to the nearest tenth to finally get [tex]a[/tex] ≈ [tex]8.3[/tex]
This means that 8.3 is just the length of side a, which is the length between the surface of where the water’s filled and the center of the circle. But, now you need to add 13 to 8.3 to find the total depth of the water because the length of the radius is included with the depth of the water.
So,
13 + 8.3 = 21.3
Answer: The depth of the water is approximately 21.3 cm

A rectangle has a diagonal of 15ft. The width of the triangle is 12ft. What is the area of the rectangle.
9514 1404 393
Answer:
108 ft²
Step-by-step explanation:
The length of the other side of the rectangle can be found using the Pythagorean theorem.
15² = 12² + x²
x = √(225 -144) = √81 = 9
So, the rectangle is 9 ft by 12 ft. Its area is the product of those dimensions:
A = bh
A = (12 ft)(9 ft)
A = 108 ft² . . . . area of the rectangle

Two brothers, Michael and Alan, were in a bowling league that met once a
week. From past experiences, it is known that both brothers' scores are
approximately normally distributed where Michael has a mean score of 150
with a standard deviation of 30, and Alan has a mean score of 165 with a
standard deviation of 15. Assuming that their scores are independent, which
of the following values is closest to the probability that Michael will have a
greater core than Alan in a single game?
0.16
0.28
0.31
0.33
0.37
Answer:
The correct option is;
0.28
Step-by-step explanation:
The given parameters are;
The mean score for Michael, [tex]\bar x _1[/tex] = 150
The standard deviation, σ₁ = 30
The mean score for Alan, [tex]\bar x _2[/tex] = 165
The standard deviation, σ₂ = 15
Taking n₁ = n₂ = 1
[tex]z=\dfrac{(\bar{x}_{1}-\bar{x}_{2})-(\mu_{1}-\mu _{2} )}{\sqrt{\dfrac{\sigma_{1}^{2} }{n_{1}}-\dfrac{\sigma _{2}^{2}}{n_{2}}}}[/tex]
Taking μ₁ - μ₂ = 0
[tex]z=\dfrac{(150-165)}{\sqrt{\dfrac{30^{2} }{1}-\dfrac{15^{2}}{1}}} \approx -0.577[/tex]
The p-value for a z-score of -0.577 from the z-table is 0.28434
Therefore, the probability that Michael, with mean score, [tex]\bar x _1[/tex] = 150 will have a greater score than Alan, with a mean score of [tex]\bar x _2[/tex] = 165 is 0.28434 ≈ 0.28
Therefore, the correct option is 0.28

Distance problems are word problems that involve the distance an object will travel at a certain average rate for a given period of time.
The formula for distance problems is: distance = rate × time or d = r × t.
Things to watch out for:
Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is given in minutes then change the units appropriately.
It would be helpful to use a table to organize the information for distance problems. A table helps you to think about one number at a time instead being confused by the question.
Distance Problems: Given Total Time
Example:
John took a drive to town at an average rate of 40 mph. In the evening, he drove back at 30 mph. If he spent a total of 7 hours traveling, what is the distance traveled by John?
Solution:
Step 1: Set up a rtd table.
r
t
d
Case 1
Case 2
Step 2: Fill in the table with information given in the question.
John took a drive to town at an average rate of 40 mph. In the evening, he drove back at 30 mph. If he spent a total of 7 hours traveling, what is the distance traveled by John?
Let t = time to travel to town.
7 – t = time to return from town.
r
t
d
Case 1
40
t
Case 2
30
7 – t
Step 3: Fill in the values for d using the formula d = rt
r
t
d
Case 1
40
t
40t
Case 2
30
7 – t
30(7 – t)
Step 4: Since the distances traveled in both cases are the same, we get the equation:
40t = 30(7 – t)
Use distributive property
40t = 210 – 30t
Isolate variable t
40t + 30t = 210
70t = 210
210/70
Step 5: The distance traveled by John to town is
40t = 120
The distance traveled by John to go back is also 120
So, the total distance traveled by John is 240
Answer: The distance traveled by John is 240 miles.

The data manager for a state political party gathered data to determine how many citizens would support the party's senate candidate. He polled citizens in 30 similarly sized senate districts and found a sample mean of 70,438 citizens. Statewide data shows that the population standard deviation is 645.3. What is the approximate 90% confidence interval for this situation?
Answer:
The approximate 90% confidence interval is;
70,244 to 70,732
Step-by-step explanation:
Here, we want to calculate the approximate 90% C.I for the situation
Mathematically;
CI = mean ± (z * SD)/√n
From the question;
mean = 70,438
SD = 645.3
n = 30
we can get z from the CI table
90% CI is same as; 1.645 z-score
So , substituting these values;
CI = 70,438 ± ( 1.645 * 645.3)/√30
CI = 70,438 ± 194
So the CI = 70,438 -194 to 70,438 + 194
= 70,244 to 70,732
Answer:
B. 70,244 and 70,632
