Find the total surface area of the pyramids below

Answer:

I think it would be 4x

Step-by-step explanation:

Heres how. At first you ignore the exponent (you'll come back to it) 12x ÷ 6x = 2x. Then you have to solve with the exponent. 2 × 2 = 4 then add the label. 4x, and that's how you get the answer. Hope this helps.

Answer:

0.5

Step-by-step explanation:

At 3, the radius was about 1. At 7 it was about 1.5. Giving us a difference of 0.5.

I might be wrong

The approximate average rate of change in the radius of the circle as the area increases from 3 square feet to 7 square feet is 0.125 foot per square foot

The rate of change formula gives the relationship describing how one quantity changes in relation to the change in another quantity. The rate of change from the coordinates of y to coordinates of x can found out as

rate of change =  [tex]\frac{Change in y}{Change in x} =\frac{(y2 - y1 )}{(x2 - x1 )}[/tex]

According to the question

The area increases from 3 square feet to 7 square feet

i.e, Change in x = 7-3

                         = 4 square feet

Between  area increases from 3 square feet to 7 square feet  radius changes form 1 to 1.5 feet

i.e, Change in y = 1.5 - 1

                          =  0.5 feet

As,

rate of change =  [tex]\frac{Change in y}{Change in x} =\frac{(y2 - y1 )}{(x2 - x1 )}[/tex]

substituting the values

rate of change = [tex]\frac{0.5}{4}[/tex]

                          = 0.125 foot per square foot

Hence, the approximate average rate of change in the radius of the circle as the area increases from 3 square feet to 7 square feet is 0.125 foot per square foot

Answer:

B

Step-by-step explanation:

Well you first know that your y-intercept is -2 (look on the graph) so you can automatically cancel out option A and D. Now this leaves us with B and C. The only thing that is different between the two answers is the slope. Slope = Δy/Δx (change in y divided by change in x) So from (0,-2) to the next point (4, -1) How far is the x and y? Well you go up one and to the right 4. the change in y is up one (+1) and the change in x is right 4 (+4).

You can also do this

\frac{-2-(-1)}{0-4} = \frac{-1}{-4} = 1/4\\

(y2-y1)/(x2-x1) (the numbers are subscripts)

Answer:

D. about 7 cm

Step-by-step explanation:

You can use the pythagorean theorem.

You have a triangle with sides of 5 and 5, so that means the third side is:

[tex]a^2 + b^2 = c^2 --> 5^2 + 5^2 = c^2\\25 + 25 = c^2\\50 = c^2\\c = 5\sqrt{2}[/tex]

rounding:

[tex]5\sqrt{2} = 7[/tex]

The answer is in fact D!

Answer:

False. A 200-ounce bag would weigh more than a 12-pound bag.

Hope this helps!

The statement "A 12-pound bag weighs more than a 200-ounce bag." is True.

The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.

Given:

A 12-pound bag weighs more than a 200-ounce bag.

As, we know

1 pound = 16 ounce

So, the weight of bag in ounces

=12 pound

= 12 x 16

= 192 ounce

So, the statement is True.
