Calculate the value of p and the value of q
Answers
Answer:
q= 20 p= 56
Step-by-step explanation:
A angle is also 62°
Answer:
q = 20 degrees
p = 59 degrees
Step-by-step explanation:
to find q, find all the other interior angles within that shape and subtract it from 360
angle E = 180 - 62 = 118
angle b = 90
angle c = 132
360 - (118 + 90 + 132) = 20
angle q = 20 degrees
to find p, add all the other interior angles within that shape and subtract it from 180
angle e = 62 degrees
angle a and b are the same so, take 62 and subtract it from 180 then divide the answer by 2
180 - 62 = 118
118 / 2 = 59
angle a = 59 degrees
angle p = 59 degrees

A rectangle prisms base is 8 feet long. It is 2 1/2 times taller than it is long and 1/2 wide as it is tall. What is the volume of the rectangular prism?
Answers
Answer:
1600 cubic feet

d. x = 15, y= 15√3
EXPLANATION:
This is a special triangle, more specifically a 30-60-90 degree triangle. For sake of not confusing x and y, we will use z to use as our reference for solving this triangle. The side lengths for each angle are as follows:
• 60 degrees = z√3
- this is the value for your y answer
• 30 degrees = z
- this is the value for your x answer
• Hypotenuse = 2z
- this is what we already have
We solve for what we already have which is the Hypotenuse = 30:
2x = 30
x = 15
We now have our x value which is 15.
Now we just plug in that x value for every expression for every angle.
x = 15
y = 15√3

15. A rectangle has a length of 2x - 1 and a width of 3x + 7. Find the perimeter of this rectangle.
Then find the area of the rectangle.
Answers
Answer:
10x + 12 and 6x² + 11x - 7
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is length and w is width )
= 2(2x - 1) + 2(3x + 7) ← distribute parenthesis
= 4x - 2 + 6x + 14 ← collect like terms
= 10x + 12
--------------------------------------------------
The area (A) of a rectangle is calculated as
A = lw
= (2x - 1)(3x + 7) ← expand using FOIL
= 6x² + 14x - 3x - 7 ← collect like terms
= 6x² + 11x - 7
For the function y = 4x – 1, what is the output when the input is 10?

since y is the output, the output is 39.
Perry deposits $175 into a simple interest account. The interest rate for the account is 4.25%. What would his final balance be in his account after 3 years?
Answers
Answer:
$197.31
Step-by-step explanation:
Given data
Principal= $175
Rate= 4.25%
TIme= 3 years
The expression for the simple interest is given as
A=P(1+rt)
substitute
A= 175(1+0.0425*3)
A= 175(1+0.1275)
A= 175(1.1275)
A= $197.31
Hence the balance will be $197.31

Harold cut 1812 inches off a rope that was 60 inches long. How is the length of the remaining rope in inches written in decimal form
Answers
Answer:
0.42
Step-by-step explanation:
The computation of the length of the remaining rope in inches is shown below:
Length Remaining = Length - the piece he cut off
Length Remaining = 60 - 18
60 - 18 = 42
To turn 42 into a decimal, you have to divide by 100 ↓
42 ÷ 100 = 0.42
The length of rope remaining is 0.42 inches long

An angle measures 3.2° less than the measure of its complementary angle. What is the measure of each angle?
Answers
Answer:
43.4° and 46.6°Step-by-step explanation:
x - measure of angle
x + 3.2° - measure of its complementary angle
Complementary angles adds to 90°
x + x + 3.2° = 90°
2x = 90° - 3.2°
2x = 86.8°
x = 86.8°÷2
x = 43.4°
x+3.2° = 43.4° + 3.2° = 46.6°
At a birthday party, Vivian counts 15 vanilla ice cream cups and 25 chocolate ice cream cups. Which properties can be used to determine the percent, p, of the ice cream that is chocolate?
Answers
Answer:
62.5 %
Step-by-step explanation:
The percentage, p of the ice cream that is chocolate is p = total number of chocolate ice cream cups/total number of ice cream cups × 100%
Given that there are 25 chocolate ice cream cups and 15 vanilla ice cream cups, total number of ice cream cups = 25 + 15 = 40
So, p = total number of chocolate ice cream cups/total number of ice cream cups × 100%
p = 25/40 × 100%
p = 25/4 × 10 %
p = 6.25 × 10 %
p = 62.5 %

The side links of a triangle are 3 m, 4 m common 5 m. Suppose the side links are multiplied by four. Describe the change in perimeter
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Side links are : 3m, 4m, 5m
The perimeter of a triangle = (a + b + c)
Perimeter 1= (3 + 4 + 5) = 12m
If the side links are multiplied by 4 :
3*4 = 12 m
4*4 = 16m
5*4 = 20m
Perimeter2 = (12 + 16 + 20) = 48 m
Comparing the perimeters:
Perimeter 1 = perimeter 2
12 = 48
Hence, perimeter also increases by 4 folds
