Pancho built a cabinet shaped like a rectangular prism. The length of the base is 6 inches, and the width is 70 inches. What is the area of the base of the cabinet in square inches?

Answers

Answer:

420in^2

Step-by-step explanation:

Given data

Length of base= 6 in

Widht of base= 70 in

We know that area= Length*Width

substitute

Area= 6*70

Area= 420 in^2

Hence the area of the base is 420in^2

Which equation can be used to find the area of the composite figure pictured below?
7 m
8 m
15 m
: A = 24 (8) + (15 x 7)
= A= 8 (15) + (15 x 7) + }(9 x 8) = A= 8 (15) + 15 (7) +9 (8)
: A = 15 (15) + (9 x 8)

Answers

Answer:

A.

Step-by-step explanation:

The figure is made up of a rectangle and two triangles.

The dimensions of the 3 polygons are:

Rectangle: 8 m by 15 m

Triangle 1: 15 m base and 7 m height

Triangle 2: 9 m base and 8 m height

Answer:

tan

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{b}{4.5}[/tex] ( multiply both sides by 4.5 )

4.5 × tan23° = b , then

Find the values of a and b so that the solution of the linear system is (-9,1).
ax + by = -31
ax – by = -41

Answers

Answer:

Step-by-step explanation:

we can write -9 instead of x and y=1 instead of 1

so we write solution again

-9a+1b=-31

-9a-1b=-41

-18a=-72

a=4

we should write 4 instead of a

-9(4)+1b=-31

-36+b=-31

b=5

a=4

Cone a and cone b both have a height of 5 in. The volume of cone a is 20.9cubic in, the volume of cone b is 4 times the volume of cone a, about how many times longwr is the diameter of cone b than the diameter of cone a?

Answers

Answer: two times

Step-by-step explanation:

Given

height of cone A and B  [tex]h_a=h_b=5\ in.[/tex]

The volume of cone A  [tex]V_a=20.9\ in.^3[/tex]

The volume of cone B is 4 times of cone A

the volume of a cone is  [tex]\frac{1}{3}\pi r^2h[/tex]

The volume of cone A

[tex]V_a=\dfrac{1}{3}\pi r_a^2h_a=20.9\quad \ldots(i)[/tex]

The volume of cone B

[tex]V_b=\dfrac{1}{3}\pi r_b^2h_b=4\times 20.9\quad \ldots(ii)[/tex]

divide (i) and (ii) we get

[tex]\Rightarrow \dfrac{r_a^2}{r_b^2}=\dfrac{1}{4}\\\Rightarrow \dfrac{r_a}{r_b}=\sqrt{\dfrac{1}{4}}=\dfrac{1}{2}\\\Rightarrow \dfrac{d_a}{d_b}=\dfrac{1}{2}\\\Rightarrow d_b=2d_a[/tex]

thus, diameter of cone B is twice the diameter of A
