Answer:

Step-by-step explanation:

(5√3*√3)+(5√3*5)+(-1*√3)+(-1*5)

5*3+25√3-√3-5

15+24√3-5

**24√3+10**

Then to solve the second, apply division rules within the radical. This means you can cancel an m^1 and n^4 from the bottom and top of the fraction. This leaves...

3√(88m^19*n^8)

(That might be all you need to do, otherwise you can take the square root of each number in the term giving...

3(√88)*m^9.5*n^4)

Hope I made it clear enough

Answer:

Step-by-step explanation:

im assuming you mean (3+5)^2-9/3+4 so just remember PEMDAS! start with 3+5 which equals 8 and square it to make it 64. then 9/3=3 (but not 64-9 since all division and multiplication need to be done first) and subtract that from 64 to get 61. add 4 and you get 65

I need to find the easiest way to learn how to divide fractions and mixed fractions. I also don't get how to simplify. 5 1/2 div

Crazy boy [7]

5 1/2 can be expressed as,

$5\text{ }\frac{1}{2}=\frac{5\times2+1}{2}=\frac{10+1}{2}=\frac{11}{2}$

If a fraction x/y is divided by a/b another fraction,

$\frac{\frac{x}{y}}{\frac{a}{b}}=\frac{x}{y}\times\frac{b}{a}$

So, 11/2 divided by 3/6 is

$\frac{\frac{11}{2}}{\frac{3}{6}}=\frac{11}{2}\times\frac{6}{3}=\frac{11}{2}\times2=11$

Therefore, 5 1/2 divided by 3/6 is 11.

The weight of an object on Mars m is 40% of its weight on Earth w. Write a function rule for the situation. Then find the weight

Marrrta [24]

Answer: The weight of space probe on Mars is 6 lb.

Write a function rule for each situation. Then use your function as indicated. The force of gravity is less on Mars than it is on Earth. As a result, the weight of an object on Mars m is 40% of its weight on Earth w. Use your function to find the weight on Mars of a space probe that weighs 15 lb on Earth.

m is weight on Mars

w is weight on Earth

m is 40% of w

f(w) = m = (40/100)w

The weight of space probe is 15 lb on Earth

substituting w = 15 in the function we get,

f(15) = m = (40/100)15

= 6

ANSWER: The weight of space probe on Mars is 6 lb.

Step-by-step explanation:

Answer:

Hence, the answer is 40 pounds.

Step-by-step explanation:

An object that weighs 50 pounds on mars weighs 150 pounds on earth.

Let the object weighing 120 pounds on Earth, weighs x pounds on Mars.

We can solve this equation as :

x = 40 pounds

Hence, the answer is 40 pounds.

Or we can also solve this as :

150 pounds on Earth weighs 50 pounds on Mars.

1 pound weighs = pounds on Mars

And 120 pounds will weigh = pounds on Mars.

Key Club hosted a fundraising event where the profit they made depends on the number of people. If 100 people attend they make $

SSSSS [86.1K]

Answer:

The linear equation that represent this problem is $y=50x-2,500$

Step-by-step explanation:

Let

x -----> the number of people

y ----> the profit in dollars

we have

For x=100, y=2,500

and

For x=80, y=1,500

Find the slope m

we have

(80,1,500) and (100,2,500)

The slope is equal to

$m=(2,500-1,500)/(100-80)\\ \\m=50\frac{\$}{people}$

Find the equation of the line into point slope form

$y-y1=m(x-x1)$

we have

$m=50$ and point (100,2,500)

substitute

$y-2,500=50(x-100)$ ----> equation in slope point form

Convert to slope intercept form

$y=50x-5,000+2,500$

$y=50x-2,500$

Jennifer planted a tree that was 0.17 of a meter tall. After 10 years, the tree was 100 times as tall as when she planted it. Wh

Travka [436]

To solve, you need to carry the decimal two spaces to the right because there are two zero in 100 so 0.17 times 100 is 17. The height of the tree after ten years was 17 meters tall in height.
