1 answer:

snow_lady [41]3 years ago

4 0

Answer:

352 m

Step-by-step explanation:

The area of a trapeze is (the biggest base + the smallest base) × height / 2

The area from rectangles are side a × side b

Trapeze: (6+12)×4/2 = 36

Rectangles: 5 × 10 = 50

6 × 10 = 60

12 × 10 = 120

There are two trapeze andtwo rectangles with the samesize, so you double their area:

2×36 + 2 × 50 + 60 + 120 = 352 m

I dont know how to do it like how to graph the -x or the y

geniusboy [140]

Answer:

see explanation and attachment

Step-by-step explanation:

(1) y = -x + 2

so slope is -1 and y-intercept is (0,2)

(2) 2x - y = 7

y = 2x - 7

so slope is 2 and y-intercept is (0,-7)

5.) If all the edges of prism A are multiplied by 5 to create prism B. The volume of prism B will be __________ times the volume

zimovet [89]

Question:

If all the edges of prism A are multiplied by 5 to create prism B. The volume of prism B will be __________ times the volume of prism A?

* 5

* 125

* 50

* 25

Answer:

* 5 times.

Step-by-step explanation:

Let us represent all the edges of prism A as = X

Prism B = All the edges of Prism A × 5

Prism B = X × 5

= 5X

Let's assume the prism is a cube

Volume of a Prism(cube) = L × W × H

Volume of Prism A = L × W × H

Volume of Prism B = 5 (L × W × H)

Therefore, The volume of prism B will be 5 times the volume of prism A

Based on the graph below, what is the total number of solutions to the equation f(x) = g(x)?

Reika [66]

Answer:

The total number of solutions is one

Step-by-step explanation:

we have

$f(x)=-\frac{11}{3}x+ \frac{11}{3}$

$g(x)=x^{3}+2x^{2}-x-2$

To solve the system of equations equate f(x) and g(x)

$f(x)=g(x)$

The solution of the system of equations is the intersection points both graphs

Using a graphing tool

see the attached figure

The solution of x

$x=1$

There is only one point of intersection both graphs

therefore

The total number of solutions is one
