Answers

A) The area of the bottom of the round pan is greater than the area of the bottom of the rectangular pan by about 8.5 square inches

Step-by-step explanation:

The complete question is the attached figure

step 1

Find the area of the bottom of the round pan

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=10/2=5\ in$ ---> the radius is half the diameter

assume

$\pi =3.14$

substitute

$A=(3.14)(5)^{2}=78.5\ in^2$

step 2

Find the area of the bottom of the rectangular pan

The area of a rectangle is equal to

A=LW

we have

$L=10\ in\\W=7\ in$

substitute

$A=(10)(7)=70\ in^2$

Verify each statement

A) The area of the bottom of the round pan is greater than the area of the bottom of the rectangular pan by about 8.5 square inches.

The statement is true

Because

$78.5\ in^2-70\ in^2=8.5\ in^2$

B) The area of the bottom of the round pan is greater than the area of the bottom of the rectangular pan by about 244.2 square inches

The statement is false

Because, the area of the bottom of the round pan is greater than the area of the bottom of the rectangular pan by about 8.5 square inches

C) The area of the bottom of the round pan is less than the area of the bottom of the rectangular pan by about 7.2 square inches

The statement is false

Because, the area of the bottom of the round pan is greater than the area of the bottom of the rectangular pan by about 8.5 square inches

D) The area of the bottom of the round pan is less than the area of the bottom of the rectangular pan by about 38.6 square inches

The statement is false

Because, the area of the bottom of the round pan is greater than the area of the bottom of the rectangular pan by about 8.5 square inches

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

Answer from: Quest

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
Find the slope of the line parallel to each given line

Find the slope of the line parallel to each given line
