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?

Answers

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!!!!

10.85 ft

Answers

Perimeter of the semicircle window = pi*r+base
=3.14*1.25+2.5
=6.425 ft
Approximately = 6.43 feet

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.

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.

Answers

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?

Answers

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 is a better deal and why? Giant: $19.50 for 2.75 pounds beef chuck OR
Sam’s Club: $35 for 5 pounds of beef chuck

Answers

Sams is a better deal. With Giants, buying the same amount as Sams costs more so it’s not as good a deal.
Price/weight will give you cost per pound. (19.50/2.75)=$7.09/lb. (35/5)=$7/lb. since sams has the lower cost per pound, it is the better deal. (Remember to make sure both rates have the same unit. $/lb and $/lb or $/kg and $/kg

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)
