Answer:

First let's work out the lengths of each side using the equation

(y2-y1)²+(x2-x1)² and then find the square root of your answer

We get BC as root of 26

AB as root of 113

AC as root of 85

To get the perimeter of the triangle add up the values

root of 85+root of 113+root of 26=24.95 (use the unit specified)

I know the answer is a bit rushed but if you do have any questions let me know

Answer:

Slope=3/4

Step-by-step explanation:

1) Label all values with x1 y1, x2 y2

Then, plug jn each value into this equation:y2-y1/x2-x1

Remember that negative values will become positive when dealjng with a subtraction sign.

5-(-1)=5+1.

---------------= 6/8

6-(-2)=6+2

After getting 6/8, simplify by the gcf (2) to get 3/4

A rectangular aquarium 3 ft. x 2 ft. 1 ft. is 2/3 full of water. In cubic feet, how much water is in the tank

tatuchka [14]

To find the volume of a rectangular prism, we must multiply the length * width * height.

In this case,

Volume = 3 ft * 2 ft * 1 ft

= 6 ft^3

Because this tank is 2/3 full with water, to find out how much water is in the tank, we must multiply 2/3 by the total volume of the tank (6 ft^3).

2/3 * 6 ft^3 = 4 ft^3

This means that there are 4 cubic feet of water in the tank.

Hope this helps!

Nicole has $20 to spend on dinner for herself. She wants to tip 20% on the amount of her meal. Which of the following are amount

Sophie [7]

Answer:

Total amount spent for meal = $16.65

Step-by-step explanation:

Given:

Amount spent on dinner = $20

Tip = 20%

Find:

Total amount spent for meal

Computation:

Total amount spent for meal = Amount spent on dinner / (1+tip)

Total amount spent for meal = 20 / 1.2

Total amount spent for meal = 16.666

Total amount spent for meal = $16.65

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r

Vitek1552 [10]

Step-by-step explanation:

We are given this function:

y=8700* (1.04)^{4}y=8700∗(1.04)

8700 is the initial amount.

1.04 shows the change of original amount. This is decimal form of percentage. We need to transform it into regular percentage.

1.04 * 100% = 104%

Now we observe this number. If it is greater than 100% we have growth, if it is lower than 100% it is decay, and if it is equal to 100% than there is no change.

In our case this number is greater than 100% so we have growth. To determine the percentage rate we must substract 100% as it represents the original amount.

104% - 100% = 4%

This would be our solution if we don't have an exponent.

We have exponent so first step is to calculate the number and then we repeat the steps from above.

1.04^{4} = 1,169858561.04

=1,16985856

1,16985856 * 100% ≈ 116,99%

116.99% - 100% = 16.99%

So, final solution is growth of 16.99%
