Answer:

B. 9

Step-by-step explanation:

When there are exponents with the same base in a fraction, they can be simplified by subtracting.

We can take out 2 on both the top and bottom, leaving us with 3^2 over 1

3x3 is 9 and 9/1 is still 9

Answer:

9

Step-by-step explanation:

Since the bases are the same, we can subtract the exponents to accomplish the division

a^b / a^c = a^ (b-c)

3^4 / 3^2

3^ (4-2)

3^2

9

A scientist had 3 1/2 liters of vinegar. He poured 2/3 of the vinegar into beaker. He then used 3/5 of the vinegar in the beaker
valentinak56 [21]

Answer:

A)2100 ml

Step-by-step explanation:

Given total vinegar is 3 1/2 liters and the used vinegar is  3/5 of the vinegar in the beaker:

#First calculate the amount of vinegar not poured in the beaker:

V_o=V_t-V_b\\\\=3\frac{1}{2}(1-\frac{2}{3})\\\\=1\frac{1}{6}

#Calculate amount of vinegar used in experiment:

V_b=\frac{2}{3}V_t=\frac{2}{3}(3\frac{1}{2})=2\frac{1}{3}\\\\V_u=\frac{3}{5}V_b=\frac{3}{5}\times 2\frac{1}{3}=1\frac{2}{5}

#The unused vinegar is therefore calculated by subtracting the used vinegar from the total at the start of the experiment:

V_r=V_t-V_u\\\\=3\frac{1}{2}-1\frac{2}5}\\\\=2\frac{1}{10}\times 1000\ ml\\\\=2100\ ml

Hence, the unused vinegar is 2100 ml

An angle measures 70° more than the measure of its supplementary angle. What is the measure of each angle
jekas [21]

Answer:

55° and 125°

Step-by-step explanation:

Formulate an equation x + (x+70) = 180

Combine like terms to get 2x + 70 = 180

Subtract 70 on both sides to get 2x = 110.

Divide both sides by 2 to get x = 55.

Add 70 to 55 to get 125.

Check your answer by adding 55 + 125. It equals 180, so the angles are equal to 55 and 125.

Can you help me on attached picture
saveliy_v [14]

Answer:

its 15 lol

this is elementary school or something???

Step-by-step explanation:

IF

3 * x =9

then do 9/3=3

So you are multiplying by 3

So therefore you would do that to 5 so its 9/15

and 9/15 and 3/5 are the same, just that 9/15 isnt simplified

hope this helps have a nice day!!
