Answer:

No, it is 6.60

Step-by-step explanation:

We need to know the cost of 1 pound, so we have to do 3.60 divided by 3, to get the cost of 1 pound, which is 1.20

We times 1.20 by the amount of pounds we need, (5.5,) and get 6.60.

If it was times just 5 pounds, than yes, it would be correct, but we need to look out for decimals too.

Answer:

d. $6.60

Step-by-step explanation:

3 cost 3.60, then 5.5 would cost ?

So we have to find what multiplied with 3 would equal 5.5, so:

5.5/3, we can't simplify this fraction so we'll just use it to multiply 3.60

3.60 × 5.5/3 = 19.8/3 = 6.6

Answer:

6433.98 ft

Step-by-step explanation:

In order to find what 25% of the tank's capacity is, we know to know the full capacity of the tank then take 25% of that. The volume formula for a right circular cone is

$V=\frac{1}{3}\pi r^2h$

We have all the values we need for that:

$V=\frac{1}{3}\pi (16)^2(96)$

This gives us a volume of 25735.93 cubic feet total.

25% of that:

.25 × 25735.93 = 6433.98 ft

The curved part of this figures is a semicircle.

vovangra [49]

First we join the two endpoints of the semicircle and that will be the diameter.

And to find the length of the diameter, we have to use distance formula, with one endpoint (3,2) and the other is (-4,-2) .

SO we get

$Diameter = \sqrt{ {-4-3)^2 +(-2-2)^2 } = \sqrt{49+16} = \sqrt 65$

Radius is half of diameter, so the radius is

$Radius= \frac{ \sqrt{65}}{2}$

Formula of area of circle is

$Area = \pi r^2$

So the area of semicircle is

$=(1/2) \pi ( \frac{ \sqrt{65}}{2})^2 = 8.125 \pi \square \units$

And the other figure is a triangle, with

$Base = 3-(-4)=3+4=7 \\ height = 2-(-2) = 2+2 =4$

$Area = (1/2)*4*7= 14 square units$

Therefore, total area is the sum of area of semicircle and area of triangle,

And we will get

$Total \ area= 14 + 8.125 \pi \ units^2$

Correct option is the third option .
