Answer:
63 cm^2
Step-by-step explanation:
p = l + w + l + w
32 = 2l + 2w
32 = 2(w + 2) + 2w
32 = 2w + 4 + 2w
32 = 4w + 4
28 = 4w
7 = w
l = w + 2
l = 7 + 2
l = 9
Check your work:
32 = 9 + 7 + 9 + 7
32 = 32
Correct
A = l × w
A = 9 × 7
A = 63

Answer:
∠ PTQ = 70°
Step-by-step explanation:
The angles subtended by the radii and tangents to the circle , sum to 180°
∠ PTQ + 110° = 180° ( subtract 110° from both sides )
∠ PTQ = 70°
Scores on a test are normally distributed with a mean of 200 and a standard deviation of 12. Find each probability
Complete question is;
Scores on a test are normally distributed with a mean of 200 and a standard deviation of 12. Find the probability that a randomly selected student scored less than 218.
Answer:
0.93
Step-by-step explanation:
We are given;
Mean; μ = 200
Standard deviation; σ = 12
Random value; x¯ = 218
Z-score formula is;
z = (x¯ - μ)/σ
z = (218 - 200)/12
z = 18/12
z = 1.5
From z-table, attached, probability = 0.93
Sarah is finding the surface area of a cube. Find the surface area of the cube with dimensions of 8 cm each
Answer:
384 cm^2
Step-by-step explanation:
A = 6a^2 (a = side length)
A = 6(8^2)
A = 6(64)
A = 384 cm^2
More explain stuff:
a^2 is what is used to find the area of a 2 dimensional square. You can also use a · a. Remember, a = side length. Since there are 6 sides/faces in a cube, you multiply the area of each face by 6. :D

find the area of the shape below
Answer:
235 cm²
Step-by-step explanation:
Find area of the large rectangle on the bottom. To do that, find its length and width, then multiply them together.
Length of big rectangle=20 cm
Width of big rectangle=9 cm
20x9=180 cm²
Next, find the area of the small rectangle on the top. To do that, find its length and width, then multiply them together.
Length of small rectangle=11 cm
Width of small rectangle=5 cm
I found the width by subtracting 9 from 14, since the 9 cm is part of the large rectangle.
11x5=55 cm²
Add the areas of the two rectangles.
55+180=235 cm²

Find the shaded angle
Answer:
332°
Step-by-step explanation:
Given is an isosceles triangle,
Measures of base angles of an isosceles triangle are equal.
Therefore,
Measure of central angle
= 180° - ( 76° + 76°)
= 180° - 152°
= 28°
Measure of shaded angle
= 360° - 28°
= 332°

The total surface area of the block is 32.6 square inches.
Given that, Jake has a block shaped like the prism shown in a set of toys.
What the surface area of a prism?To find the surface area of any kind of prism we use the general formula. The total surface area of a prism is the sum of lateral surface area and area of two flat bases.
The total surface area of a prism = (2 × Base Area) + (Base perimeter × L).
Here, area = 2 ×1/2×2×2.3 +(2+2.5+2.5)×4
= 4.6+28
= 32.6 square inches
Therefore, the total surface area of the block is 32.6 square inches.

Solve the equation. 36^6x-1 = 6^5x
The solution of the equation 36⁶x - 1 = 6⁵x is x = 1/2176774560.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
We have the equation:
36⁶x - 1 = 6⁵x
Simplifying,
(6²)⁶x - 1 = 6⁵x
6¹²x - 6⁵x = 1
2176782336x - 7776x = 1
x = 1/2176774560

A trampoline was originally priced at $100 but went on sale for 60% off. If Emmett bought the trampoline and paid 5% sales tax, how much did he pay in total? $
Answer: $42
Step-by-step explanation:
Since the trampoline was originally priced at $100 but went on sale for 60%, the price paid will be:
= $100 - (60% × $100)
= $100 - (0.6 × $100)
= $100 - $60
= $40
Emmett bought the trampoline and then paid 5% sales tax, the total amount paid will be:
= $40 + (5% × $40)
= $40 + (0.05 × $40)
= $40 + $2.
= $42
She paid $42 in total.

L = 4 units
w*h = 2 1/8 units^2
V=L* (w*h)
V = 4 * (2 1/8)
V = 8 1/2
Where did the 1/2 come from?
You could write 2 1/8 as 2 + 1/8 and use the distributive property.

Find the values of x and y
Answer:
y = 70 degrees
x = 11
Step-by-step explanation:
The side opposite x + 2 is equivalent so they will both be equal to 13.
To get the meaning of x, simply subtract 2 from 13 giving you x = 11.
Y is across from corner C, which is 70 degrees. These angles are equivalent to each other, meaning that angle y is also 70 degrees.
Hope this helps you :)
Answer:
x = 11
y = 70°
Step-by-step explanation:
x + 2 = 13
The lines on each side are corresponding.
11 + 2 = 13
Y is corresponding with the 70° corner.
That means the corresponding corner (y) is also 70°.
