Answer: 15

Step-by-step explanation: 2 minus negative 1 is the same as 2+1. 2 plus 1 is 3 and 5 times 3 is 15. Therefore, 15 is your answer.

How do you write 3.25 in simplest form
dedylja [7]
3.25 would be 3 1/4 because,

Step 1: You would rewrite the decimal number as a fraction with 1 in the denominator. So, 3.25 = 3.24/1

Step 2: Multiply it by 1 to eliminate 2 decimals places, so multiply the top and bottom by 10^2 = 100
3.25/1 x 100/100 = 325/100
Step 3: Now you find the greatest common factor, also known as GCF, of 325 and 100 if it exits then you reduce the fraction by dividing both numerator and denominator by it. GCF = 25
3.25/100 divided by 25/25 = 13/4
Now you would simplify it to make a proper fraction getting your answer
3 1/4
Does that make sense?

Which quadrant contains -11pi/18 and what is the reference angle?
vekshin1

Answer:

Option 1 is correct.

Step-by-step explanation:

Given angle \frac{11\pi}{18}. we have to find the quadrant and the reference angle.

Angle given is \frac{11\pi}{18} i.e \frac{11}{18}\times 180^{\circ}=110^{\circ}

Hence, the angle is 110° lies in second quadrant.

Now reference angle, the smallest angle that you can make from the terminal side of an angle with x-axis.

which is \pi-\frac{11\pi}{18}=\frac{7\pi}{18}

Hence, option 1 is correct.

A particular shade of paint is made by mixing five parts of red paint with seven parts of blue paint. To make the correct shade,
frutty [35]

We get that Shannon did not mix the correct shade as the ratios are not equal.

We are given that a particular shade of paint is made by mixing five parts of red paint with seven parts of blue paint.

This means that the ratio of the paints in that shade is

Red : Blue = 5 : 7.

Now, we are also given that to make the correct shade, Shannon makes 12 quarts of blue paint with 8 quarts of red paint.

Here the ratio becomes:

Red : Blue = 8 : 12

= 4 : 6

= 2 : 3

Now, since both the ratios are not equal, he did not mix the correct shade.

Therefore, we get that Shannon did not mix the correct shade as the ratios are not equal.
