A construction worker fills a mold with concrete. This solid figure represents the mold.
What is the volume of the concrete that fills the mold?
Answer:
volume = 338 x 20 = 6760 cm^3
Step-by-step explanation:
large rectangular top area = 14 x 22 = 308 cm^2
small rectangular top area = 6x5 = 30 cm^2
total top area = 308 + 30 = 338 cm^2
volume = 338 x 20 = 6760 cm^3
Which value is closest to the perimeter of the window?
WITH EXPLANATION HOW YOU GOT IT!!!!
3.93 ft
0 6.43 ft
07.85 ft
10.85 ft
The perimeter of the window is 3.93 feet.
What is perimeter?
Perimeter is the total length of the sides of a two-dimensional shape.
Formula for perimeter of the semicircle:perimeter = πr
Where, r is the radius of the circle
And, π = 3.14
According to the given question.
The window is in the shape of semicircle.
Radius of the window = [tex]\frac{2.5}{2} = 1.25 feet[/tex]
Therefore, the perimeter of the window
= π × 1.25 ft
= 3.14 × 1.25
= 3.925
= 3.93 feet
Hence, the perimeter of the window is 3.93 feet.

help? mathhhhhhhhhhhhhhhhhhhhhhhhhhhh
Answer:
a + 20 = 7*12 (multiplied both sides by 12)
a + 20 = 84 (calculated 7*12)
a = 84 - 20 (subtracted 20 on both sides)
a = 64 (calculated 84-20)

Find the volume of the cone 3ft and 2 ft. Round your answer to the nearest tenth if necessary. Use 3.14 for pie
Answer:
37.68 ft^3
Step-by-step explanation:
The parameters used in describing a cone is radius and height
Hence
Radius= 3ft
Height = 2 ft
The volume of a cone is given as
[tex]v=\frac{1}{3} \pi r^2 h[/tex]
substitute
[tex]v=\frac{1}{3}*3.14*3^2*2^2\\\\v=\frac{1}{3}*3.14*9*4\\\\v=\frac{1}{3}*113.04\\\\v=37.68 ft^3[/tex]
Hence the volume is 37.68 ft^3

Kate plans to use four triangles like the one shown to form a diamond
shape.
For her plan to work, the triangle must be a right triangle.
Determine whether the triangle is a right triangle.
Answer:
The triangle is a right triangle.
Step-by-step explanation:
In the given triangle, three sides are given.
First side = 15 cm
Second side = 17 cm
Third side = 8 cm
We need to determine whether the triangle is a right triangle. For a triangle to be a right angle, it must follow the Pythagoras theorem.
The hypotenuse is the longest side of a right triangle. Let 17 cm be the hypotenuse. So,
[tex]17^2=15^2+8^2[/tex]
Now solving RHS,
[tex]15^2+8^2=225+64\\\\=289[/tex]
Now solving LHS, 17² = 289
It implies, LHS = RHS
Hence, the triangle is a right triangle.

How can an area model help you set
up an equation for a problem situation?
Answer: In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the or the and define the length and width of the rectangle.
We can break one large of the rectangle into several smaller boxes, using number bonds, to make the calculation easier. Then we add to get the area of the whole, which is the or quotient.
Step-by-step explanation:
For example, you can find the product 23 × 37 by finding the area of a rectangle with a width of 23 and a length of 37: Of course, there is little gained if you simply multiply 23 × 37! What makes the area model useful is that area is a conserved quantity.

which of the trigonometric ratios has a value that is undefined?
Answer:
[tex]\tan \left(\frac{\pi }{2}\right)[/tex]
Step-by-step explanation:
We know that tan(x) is defined as sin(x)/cos(x):
[tex]\tan \left(\frac{\pi }{2}\right),\\\sin \left(\frac{\pi }{2}\right)=1,\\\cos \left(\frac{\pi }{2}\right)=0,\\\\[/tex]
[tex]\tan \left(\frac{\pi }{2}\right) = 1/0 \\[/tex]
1/0 is undefined as 0 is in the denominator

TABLE 2:
176

132
108
90
81
60
28
11
2
Step-by-step explanation:
When two angles are complementary they add up to 90 degrees
so for example if angle 1 is 2 angle two must equal 88 (they have to add up to 90)
When two angles are supplementary they must add up to 180 (so it's the same process as table 1 but instead of adding to 90 it's 180)
Answer:
m<2 88,80, 65, 57, 50, 41, 35, 28, 14, 4
m<4 176, 164, 132, 108, 90, 81, 60,28, 11, 2
Step-by-step explanation:
complementary means they add up to 90°
m<2 88,80, 65, 57, 50, 41, 35, 28, 14, 4
supplementary means they add up to 180°
m<4 176, 164, 132, 108, 90, 81, 60,28, 11, 2
