On number 5 you would move the decimal to the right 2 times 97.5%
on number 6 you take the 17 out of the hundred and you end up with 17%
on number 8 you divide 2 divided by 5 and you get 0.4 and you move the decimal to the right once and you get 4%
on number 9 on only 1% lives in solar homes you just move the decimal to the left once so it would be .1

Step-by-step explanation:

An equation at represents this situation is:

-5 = 3 + x

Find x by;

-5 - 3 = -8

So x is -8:

(y_final-y_start)/(x_final-x_start) always! :) that easy

(-6-2)/(2-0) = -4

You probably know that if the interval was pretty small, between 0 and 0.0001, it would take you to the concept of slope and derivatives, but average change is just ignoring anything in between x=0, and x=2 (it could go up/down million times, and still the answer would be -4)

hope it helps

Please help i have 2 questions thank you very much.

Hello!

Question 1
We first have to convert everything to yards since the concrete is charged by the cubic yards

15 feet = 5 yards
15 feet = 5 yards
3 inches = 0.08333

Multiply these to find the volume

5 * 5 * 0.08333 = 2.08325

Multiply this by the cost

2.08325 * 46 = 95.83

The answer is C) $95.83
------------------------------------------------------------------------------------------------------
Question 2

You have to find the volume of the first pyramid

The equation we use is $V = \frac{lwh}{3}$

V is volume
l is length
w is width
h is height

Put in the values we know

$V = \frac{16 * 16 * 28}{3}$

Multiply

$V = \frac{7168}{3}$

Divide

V = 2389.3333

Now we use this to find the side length of the second pyramid

$2389.333 = \frac{lw * 112}{3}$

Multiply both sides by 3

<span>7167.999 = lw * 112
</span>
Divide both sides by 112

63.9999 = lw

Since it is a square pyramid we know that sides are equal

63.999 = l^2

Take the square root of both sides

8 = l

The answer is B) 8in

Hope this helps!

Joe travels at a constant speed of 80 miles per hour for ten hours. How many miles will he travel in ten

ratelena [41]

Answer:

1287.48 km

Step-by-step explanation:

80 miles = 128.748 km

Distance = Speed x Time

Putting in 'x' for distance

x = 80*10

x = 800 miles

x = 1287.48 km
