Answer:

141.12 cm^2

Step-by-step explanation:

A = 1/2 (b1+b2)h where b1 = 10.2, b2 = 12.2 and h = 12.6

so

A = 1/2(10.2 + 12.2) * (12.6)

A = 1/2(22.4)(12.6)

A = 141.12 cm^2

Answer:

A rectangular prism in which BA = 20 and h = 6 has a volume of 120 units3; therefore, Shannon is correct

Step-by-step explanation:

step 1

Find the area of the base of the rectangular pyramid

we know that

The volume of the rectangular pyramid is equal to

V=\frac{1}{3}BH

where

B is the area of the base

H is the height of the pyramid

we have

V=40\ units^{3}

H=6\ units

substitute and solve for B

40=\frac{1}{3}B(6)

120=B(6)

B=120/6=20\ units^{2}

step 2

Find the volume of the rectangular prism with the same base area and height

we know that

The volume of the rectangular prism is equal to

V=BH

we have

B=20\ units^{2}

H=6\ units

substitute

V=(20)(6)=120\ units^{3}

therefore

The rectangular prism has a volume that is three times the size of the given rectangular pyramid. Shannon is correct

Write an inequality from (–5) to (–1) inclusive
skad [1K]

Answer:

-5\leq x\leq -1

Step-by-step explanation:

This is a compound inequality that basically states that the X value is greater than or equal to -5, but less than or equal to -1. It is inclusive, because it includes both numbers and therefore should have an equal to sign (\leq   or \geq) instead of just less than or greater than ( < or >).
