Here, we want to show that the left hand side equals the right hand side
We can express the left hand side as:
sin A/ cos A * sec A/cosec A
kindly recall that;
sin A/cos A = tan A
Also;
sec A = 1/ cos A
cosec A = 1/ sin A
Thus, we have that ;
tan A * 1/cos A / 1 / sin A
= tan A * sin A/cos A
This is;
tan A * tan A = tan^2 A

Peaches are being sold for $2 per pound.The customer created a model to represent the total cost of peaches bought. If x represents the number of pounds of peaches bought and y represents the total cost of the peaches, which best describes the values of x and y?
The values of both x and y can be any real number.
The values of both x and y will be real numbers greater than or equal to 0.
The value of x and y will always be zero
The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.
Answer:
B - The values of both x and y will be real numbers greater than or equal to 0.
The answer choice that best describes the values of x and y is B - The values of both x and y will be real numbers greater than or equal to 0.
Calculations and Parameters:Given that peaches are being sold for $2 per lb.
If we define x as the number of pounds that you buy, and y as the cost of these peaches, we can write the function:
y = $2*x
Therefore, the best description of the values of x and y is found in option B. The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

Answer:
A). Scale factor = [tex]\frac{1}{4}[/tex]
B). Length of the unknown side = 2.75 feet
Step-by-step explanation:
Part A
Since, the large rectangle was scaled by a scale factor 'k' to form the smaller rectangle,
Scale factor = [tex]\frac{\text{Side length of the image}}{\text{Side length of the preimage}}[/tex]
= [tex]\frac{\text{Side length of the smaller rectangle}}{\text{Side length of the larger rectangle}}[/tex]
= [tex]\frac{4}{16}[/tex]
= [tex]\frac{1}{4}[/tex]
Part B
Scale factor = [tex]\frac{\text{Side length of the smaller rectangle}}{\text{Side length of the larger rectangle}}[/tex]
[tex]\frac{1}{4}=\frac{\text{Side length of the smaller rectangle}}{11}[/tex]
Therefore, side length of the unknown side = [tex]\frac{11}{4}[/tex] = 2.75 feet
a particular tree is 18 m tall : a model of it was built with a. scale of 4 cm : 3m how tall is the model.
Answer:
24 cm
Step-by-step explanation:
We can set up a ratio of 18 m / x cm = 3 m / 4 cm because we know that it's a scale.
Cross multiplying, we get 3x = 72. Divide both sides by 3 and we have x = 24 cm.
We can also consider it by just dividing 18 m by 3 m to find the scale factor, which is 6. We then multiply the 4 cm by 6 to get 24 cm as well.
A baker sold 35% of the cakes she baked, if she baked 80 cakes, how many cakes did she sell?
Answer:
28
Step-by-step explanation:
find 35% off 80 cakes
35% * 80
Converting percent to decimal:
35%/100 = 0.35
0.35 * 80
28
Therefore the baker sold 28 cakes out of the 80 cakes she baked. Hope this helps!
I think 35% of 80 is 28.

13. The sum of the measures of angle Mand angle Ris 90°.
• The measure of angle Mis (5 x + 10).
• The measure of angle Ris 55°.
What is the value of x?
Answer:
x=5
Step-by-step explanation:
If the sum of the measures of angle M and R is 90 degrees, and you know that angle R is 55 degrees, subtract angle R from the total angle. Then, solve for M
90 - 55 = 35
5x + 10 = 35
5x = 25
x = 5

solve each system of equations algebraically y= x-6 y= 2x
Answer: x = -6
Step-by-step explanation: The problem gave us the y value, so we can just substitute it into the equation and solve it.
y = x - 6
y = 2x
2x = x - 6 (substitute the y value into the equation)
1x = -6 (subtract x on each side)
x = -6 (1x is basically saying x so you do not need to divide)

If Bill works on Saturdays, he earns $9 per hour (h), plus a $10 bonus for working on the weekend. He wrote a Function, f(h) = 9h + 10, to help calculate how much he would earn working different numbers of hours next Saturday. How much will Bill earn for 5 hours and 12 hours?
Answer:
[See Below]
Step-by-step explanation:
For 5 hours: f(5)
f(5) = 9(5) + 10
f(5) = 45 + 10
f(5) = 55
Bill would work earn $55 if he worked for 5 hours.
For 12 hours: f(12)
f(12) = 9(12) + 10
f(12) = 108 + 10
f(12) = 118
Bill would work earn $118 if he worked for 12 hours.
Hope this helps.

A recipe requires 3 cups of flour to make 27 dinner rolls. How much flour is needed to make 9 rolls?Mandy runs 4 km in 18 min. She plans to run in a 15 km race. How long will it take her to complete the race?
Answer:
a)1 cup of flour
b)67.5 minutes
Step-by-step explanation:
a) A recipe requires 3 cups of flour to make 27 dinner rolls. How much flour is needed to make 9 rolls?
From the above question, we know that:
27 dinner rolls = 3 cups of flour
9 dinner rolls = x
Cross Multiply
27 rolls × x = 9 rolls × 3 cups
x = 9 rolls × 3 cups/27 rolls
x = 1 cup of flour
Hence, 1 cup of flour is needed to make 9 dinner rolls
b) Mandy runs 4 km in 18 min. She plans to run in a 15 km race. How long will it take her to complete the race?
From the above question:
4 km = 18 minutes
15km = x
Cross Multiply
4km × x = 15km × 18 minutes
x = 15km × 18minutes/4km
x = 67.5 minutes
Hence, in a 15km race , it would take her 67.5 minutes to complete her race.

Write the equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x
Answer:
[tex]\displaystyle y=-\frac{2}{3}x+3[/tex]
Step-by-step explanation:
We want to find the equation of the line that is parallel to:
[tex]\displaystyle y=-\frac{2}{3}x[/tex]
And passes through (-3,5).
First, we need to determine the slope of our new line.
Remember that parallel lines have the same slope.
Since the slope of our original line is -2/3, this means that the slope of our new line must also be -2/3.
Now, we can use the point-slope form given by:
[tex]y-y_1=m(x-x_1)[/tex]
We will let (-3, 5) be (x₁, y₁). By substitution:
[tex]\displaystyle y-(5)=-\frac{2}{3}(x-(-3))[/tex]
Simplify:
[tex]\displaystyle y-5=-\frac{2}{3}(x+3)[/tex]
Distribute:
[tex]\displaystyle y-5=-\frac{2}{3}x-2[/tex]
Add 5 to both sides. So, our equation is:
[tex]\displaystyle y=-\frac{2}{3}x+3[/tex]
Answer:
[tex]\displaystyle y = -\frac{2}{3}x + 3[/tex]
Step-by-step explanation:
5 = –⅔[–3] + b
2
[tex]\displaystyle 3 = b \\ \\ y = -\frac{2}{3}x + 3[/tex]
Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so –⅔ remains as is.

H
-5 + 3x > 1
J
3 – x < 10
Answer:
J
Step-by-step explanation:
If I remember correctly then its J
Answer:
Definitely J.
Step-by-step explanation:
plug in -2 into the where the x is.
so the equation is 3 - -2<10
it becomes 3 +2<10 because the minus and negative signs cancel each other out, making the equation true.

At a state fair, each person pays $8 for admission plus $2 for each ride. While at the fair, Elizabeth goes on 6 rides. Which expression can be used to find the total amount Elizabeth spends?
Answer:
The expression is given as:
Total amount = 8 + 2x
Total amount = $20
Step-by-step explanation:
Let the number of rides Elizabeth goes on be represented by x
The expression used to find the total amount =
$8 + $2 × x
= 8 +2x
Elizabeth goes on 6 rides
Total amount =
8 + 2 × 6
= 8 + 12
= $20

Pakisagutan lang po help pls
Answer:
Step-by-step explanation:
S 50 m = 0.050 km
A ∵ 1 m = 100 cm
∴ 5 m = 500 cm
K ∵ 1000 dm = 0.1 km
∴ 1 dm = [tex]\frac{0.1}{1000}[/tex] km
∴ 5246 dm = [tex]\frac{0.1}{1000}\times 5246[/tex] km
= 0.5246 km
P ∵ 1 m = 1000 mm
∴ 5.246 m = 5246 mm
P ∵ 1 hg = 1000 dg
∴ 3.7 hg = 3700 dg
U ∵ 1 g = 100 cg
∴ 0.37 g = 37 cg
E ∵ 1 kg = 1000 g
∴ 370 kg = 370,000 g
Jada and Noah wanted to find the total volume of a cube and a rectangular prism. They know that the prisms volume is 20 cubic units, and they know that the cube has side lengths of 10 units. Jada says the total volume is 27,000 cubic units. Noah says it is 1,020 cubic units. Do you agree with either of them?
Answer:
Noah answer is the correct answer
Step-by-step explanation:
The solution to the above question is given as:
Total Volume = Volume of the prism + Volume of the cube
Volume of the prism = 20 cubic units
Volume of a cube = (Side length)³
= 10³ = 1000 cubic units
Hence: The total volume =
20 cubic units + 1000 cubic units
= 1,020 cubic units
Therefore, I agree with Noah's answer.
