Answer:

0.64

Step-by-step explanation:

So what you need to do is you have to divide 7 by 11 to get your answer.

7/11=0.6363636364

You need to round to the nearest tenth. Then the answer would be 0.64.

I hope this helps.

mike charges 100 dollars service charge plus 65 dollars per hour.

amy charges 40 dollars service charge plus 80 dollars per hour.

the cost to repair from mike is 100 + 65 * x.

the cost to repair from amy is 40 + 80 * x.

let x = 3 and you get:

the cost to repair from mike is 100 + 65 * 3 = 295 dollars.

the cost to repaid from amy is 40 + 80 * 3 = 280 dollars.

as long as the time to repair is 3 hours or less, the cost to repair will be cheaper from amy.

the functions f and g are defined as follows f(x)=-5x+2 g(x)=3x^2-3x find f(g) and g(-2) simplify your answer as much as possibl

daser333 [38]

Answer:

f(g) = -15x^2 + 15x + 2.

g(-2) = 18.

Step-by-step explanation:

f(g) = -5(3x^2 - 3x) + 2

= -15x^2 + 15x + 2.

g(-2) = 3(-2)^2 - 3(-2)

= 12 + 6

= 18.

A rectangular plot of ground is 5 meters longer than it is wide, It’s area is 20,000 square meters

Artyom0805 [142]

I'm assuming you're looking for the dimensions of the plot. I'm going with that. ;) If the length of the plot is 5 meters longer than the width, then L = w + 5. The area for a rectangle is L*w, and we have an area value of 20,000 so our formula is 20000=(w+5)(w) and $20,000=w^2+5w$ . We will bring the 20,000 over by subtraction and set the polynomial equal to 0 to factor and solve for w. $w^2+5w-20,000=0$ Solving for w we get values of w=138.9 and -143.9. Of course the 2 things in math that will never EVER be negative are time and distance/length, so -143.9 is out. Our width is 138.9 and the length is 138.9 + 5 so the length is 143.9. And there you go! Hope that's what you needed!

The table shows the average weight of animals. How many more tons does a blue whale weigh than an African elephant? Explain how

AVprozaik [17]

Answer:

The African elephant weighs <u>111.5 tons</u> less than a blue whale.

Step-by-step explanation:

Given:

Animal Weight(pounds)

African Elephant 15,000

Blue Whale 238,000

Now, to find the weight of how more tons does a blue whale weigh than an African elephant.

As given, 1 ton = 2,000 pounds.

So, to convert the weight from pound to tons by dividing:

African elephant $=15000\div 2000=7.5\ tons.$

Blue whale $=238000\div 2000=119\ tons.$

Now, to get the weight of how more tons is blue whale weigh than an African elephant we subtract:

$Blue\ whale - African\ elephant$

$=119 tons-7.5tons$

$=111.5\ tons$

Therefore, the African elephant weighs 111.5 tons less than a blue whale.

What is the supplement angle of 100?

aleksley [76]

Answer:

An angle measuring 100 degrees would be supplementary to any angle measuring 80 degrees, but it cannot be called supplementary by itself. "Complementary" and "supplementary" are terms that describe the relationship between two angles. They are comparative words like "larger."
