Can someone help me with these three questions?

N76 [4]

Answer:

1. =

2. <

3. <

Step-by-step explanation:

Note: When comparing decimals you always place both decimals right above each other.

1 is equal to because once you put a 0 behind the 2.1 they are both the same.

2.10

2.1 <add 0 as space holder

2 is less than because they are both negative you are looking for which one is closest to zero.

-4.5 <add 0 as place holder

-4.25 <closest to zero

3 is less than because $\pi$ (pie) equals 3.141592654 which is less than 3.2.

3.141 <do not need to add whole decimal

3.2 <add two 0's as a placeholder

What is the area of the figure?<br><br> 40 ft2<br> 84 ft2<br> 96 ft2<br> can't be determined

mina [271]

Answer:

$A=80\ ft^2$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of an isosceles triangle (has two equal sides) plus the area of a rectangle

step 1

Find the area of the triangle

The area of the triangle is equal to

$A=\frac{1}{2}bh$

we have

$b=16\ ft$

To find out the height of the triangle Apply the Pythagorean Theorem

$10^2=(16/2)^2+h^2$

solve for h

$100=64+h^2$

$h^2=100-64$

$h^2=36$

$h=6\ ft$

<em>Find the area of triangle</em>

$A=\frac{1}{2}(16)(6)$

$A=48\ ft^2$

step 2

Find the area of rectangle

The area of rectangle is equal to

$A=LW$

we have

$L=16\ ft\\W=2\ ft$

substitute

$A=(16)(2)=32\ ft^2$

step 3

Find the area of the figure

Adds the areas

$A=48+32=80\ ft^2$
