Step-by-step explanation:
Tony will spend at most $27 on gifts. So far, he has spent $14. What are the possible additional amounts he will spend?
Use c for the additional amount (in dollars) Tony will spend.
Write your answer as an inequality solved for c.
Answer:
Inequaltiy: 27 ≤ 14+c
Final answer: 13 ≤ c
Step-by-step explanation:
Well tony spent at most 27 dollars.
He spent 14 already and he can‘t get past 27 dollars but he can spend exactly 27 or even less.
So 27 ≤ 14+c
You would like to lease a car worth $61,815 for a three-year period. The leasing company told you that after three years, the car would have a residual value of $44,999. What percentage represents the residual value of your leased car?
Answer:
72.8%
Step-by-step explanation:
Percentage residual value = (residual value / worth of the car) x 100
(44,999 / 61,815) X 100 = 72.8%
A pro-athlete is offered an eight-year
contract with a starting salary of
$400,000. She will receive an increase
of so each year.
The athlete's salary each year forms a geometric
sequence
What is a1, in thousands?
What is r?
Answer:
400
1.05
Step-by-step explanation:
The athlete should take the second offer.
It is given by the formula,
A = P(1+r)ⁿ
where A is the value after n period of time, P is the initial amount, and,
r is the rate of increment or decrement.
Now, Total amount = $400,000(1+5%)⁷
= $400,000(1+0.05)⁷
= $400,000(1.4071)
= $562840.17
Now, the total amount that the pro-athlete will get in 8 years is,
Total amount = $425,000(1+4%)⁷
= $425,000(1+0.04)⁷
= $425,000(1.3159)
= $559,271
Since the total amount that the athlete will get in the next 8 years is more for the second offer, the athlete should take the second offer.

Two boys want to balance a seesaw perfectly. One boy weighs 240 pounds and is sitting four feet from the fulcrum. The other boy weighs 160 pounds. Where should the lighter boy sit to balance the seesaw?
Answer:
Step-by-step explanation:
Two boys want to balance a seesaw perfectly. One boy weighs 240 pounds and is sitting four feet from the fulcrum. The other boy weighs 160 pounds. Where should the lighter boy sit to balance the seesaw?
We solve using the formula
Distance on the fulcrum × Weight of the boy
= 4 × 240 = x × 160
4 × 240 = 160x
x = 4 × 240/169

Consider the two properties that you would use to solve an equation like 3x + 5 = 26. Which of the following is true?
A. The standard method for solving an equation like 3x + 5 = 26 is to use the Multiplication Property of Equality and then the Division Property of Equality.
B. The standard method for solving an equation like 3x + 5 = 26 is to use the Division Property of Equality and then the Subtraction Property of Equality.
C. The standard method for solving an equation like 3x + 5 = 26 is to use the Subtraction Property of Equality and then the Division Property of Equality.
D. The standard method for solving an equation like 3x + 5 = 26 is to use the Subtraction Property of Equality and then the Addition Property of Equality.
Answer:
The standard method for solving an equation like 3x + 5 = 26 is to use the Subtraction Property of Equality and then the Division Property of Equality.
Step-by-step explanation:
To solve, you subtract both sides by 5 first. Then you divide both sides by 3 to isolate the x.
X squared minus 3x minus 10 equals 0

What are Trignometric ratios ?The ratios of the sides of a right triangle are called trigonometric ratios.
Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).
sin = Perpendicular/ Hypotenuse
Cos = Base / Hypotenuse
tan = Perpendicular/Base
In the figure attached with the answer we can see that in Triangle ABC ,
tan 50.1 = x / 5
5(tan 50.1) = x
Therefore x is approximately equal to 6.

Solve the problems. What are the equations of the trend line shown here?
Answer:
1) y = -7/10x + 21
Step-by-step explanation:
1)
Points (5, 7) and (15, 0)
Slope:
m=(y2-y1)/(x2-x1)
m=(0-7)/(15-5)
m=(-7)/10
m= -7/10
Slope-intercept:
y - y1 = m(x - x1)
y - 7 = -7/10(x - 5)
y - 7 = -7/10x + 14
y = -7/10x + 21

Answer:
D) 8
Step-by-step explanation:
We're looking for [tex]x[/tex], which means the 7x and 5x will have the SAME x.
7(8) = 56
For the C corner, it is cornered as a 90 degree angle, so that means the (7x) + 34 degrees NEEDS to equal 90.
7(8) = 56 + 34 = 90!!
Now we have to see if 5(8) is correct
5(8) = 40 + 50 [The degree mark] = WHICH EQUALS 90 TOO..
Therefore, the answer is D) 8

Answer:
∠ H = 59°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
121° is an exterior angle of the triangle, then
6x - 1 + 5x + 12 = 121 , that is
11x + 11 = 121 ( subtract 11 from both sides )
11x = 110 ( divide both sides by 11 )
x = 10
Then
∠ H = 6x - 1 = 6(10) - 1 = 60 - 1 = 59°

What is the value of "w" ?
Answer:
w = [tex]\sqrt{147}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
w² + 7² = 14²
w² + 49 = 196 ( subtract 49 from both sides )
w² = 147 ( take the square root of both sides )
w = [tex]\sqrt{147}[/tex]
A researcher studies alcohol's effect on reaction time and finds no difference between people who consumed 1 versus 2 beverages. She included 40 participants randomly selected from the dining hall on campus, with a range in age from 18 to 38 years and a range in weight from 100 to 325 pounds. She decides to rerun her study with 30 women from 18 to 22 years of age and who are all of normal body weight and finds there is a statistical difference in reaction times between those who consumed 1 versus 2 beverages. Why might her results have changed
Answer:
Her results changed because the power increased due to the fact that she reduced variability in her data as a result of using a sample that had lesser variability.
Step-by-step explanation:
She is trying to find if there is difference between people who consumed 1 versus 2 beverages.
Now initially she surveyed 40 people between ages 18 to 38 years and of huge weights and found out there was no difference. However, she decided to run the survey again on only women aged 18 to 22 years with normal body weight.
Since she used a lesser sample size and surveyed only women, it means there will be lesser variability in the result as the sample is smaller and streamlined to only women.
Thus, her result changed because the power increased due to the fact that she reduced variability in her data as a result of using a sample that had lesser variability.

please what is the exact question
Answer:
161.56 ft^2
Step-by-step explanation:
base area = (leg 1 x leg 2)/2 = (5 x 5)/2 = 25/2 = 12.5 ft^2
base perimeter = 5 + 5 + 7.07 = 17.07 ft
lateral surface = (perimeter x height) = 17.07 x 8 = 136.56 ft^2
surface area = base area x 2 + lateral surface = (12.5 x 2) + 136.56 = 161.56 ft^2
After t seconds a ball thrown in the air from ground level reaches a given
height (h) in feet. Given the equation h = -1612 + 144 + 100 at what time does the
ball reach 100 feet?
Answer:
9 sec.
Step-by-step explanation:
I think you wrote the equations incorrectly. It probably is
[tex]h = -16t^{2} + 144t + 100[/tex]
If that is true, then [tex]100 = -16t^{2} + 144t + 100[/tex]
0 = -16[tex]t^{2}[/tex] + 144t
-16t(t - 9) = 0
t = 0 or t = 9
