the length of one leg of a right triangle is 6 feet. the length of the hypotenuse is 2 ft longer than the other leg. Find the le
Minchanka [31]

Answer:

The missing leg is 8 feet and the hypotenuse is 10 feet.

Step-by-step explanation:

Use the Pythagorean theorem which is A²+B²=C².

So we know the first side is 6 so plug that into the equation which would now be 6²+B²=C².

Because the hypotenuse is 2 feet longer than the missing leg we can plug in C=B+2 which would now make it 6²+B²=(B+2)².

Now we solve what we have so far which would now make the equation 36+B²=B²+4B+ 4.

Now we can figure out that 4B=32.

Now isolate the variable, B, by divide both side of 4B=32 by 4.

This gives us B=8.

So the other side is 8 feet.

Since we know that the hypotenuse is 2 feet longer than the leg we just add 2 feet to the original 8 feet to find the hypotenuse to be 10 feet.

F (x) =2x -4; find f (-4)
NemiM [27]

Answer:

f(-4) = -12

Step-by-step explanation:

f(x)=2x-4

To calculate f(-4), we need to substitute x in our equation above with -4:

f(x)=2x-4\\f(-4) = 2*(-4) - 4\\f(-4) = -8-4 = -12

Note that 2*(-4) = -8

Answer: f(-4) = -12

A school raised &4,589 in a sale. Mr Simmons class raised 1/100 of the money. How much did Mr Simmons class raise?
Ksenya-84 [330]

Alright, lets get started.

total amount school raised in sale = $ 4589

Mr Simmons class raised \frac{1}{100} of the money.

So, if we want to find amount of the money Mr. Simmons raised, we sould take one hundered of the total amount.

Hence money raised by Mr. Simmons class = \frac{1}{100} * 4589

Hence money raised by Mr. Simmons class = \frac{4589}{100}

Hence money raised by Mr. Simmons class = $ 45.89 : Answer

Hope it will help :)
