When Serena is 10, her mom is 3*10=30. Her mom is 20 years older than Serena.

If her mom's age divided by half is equal to Serena's, then she will be twice as old as Serena.

20 + 20 = 40
20 * 2 = 40

Serena will be 20, her mom will be 40.

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

What is the best approximation for the circumference of a circle with a radius of 125 m?
ANEK [815]

Answer:

Option B is correct

circumference of a circle is 785 m

Step-by-step explanation:

Circumference of the circle(C) is given by:

C = 2\pi r

where

r is the radius of the circle

As per the statement:

radius of the circle is 125 m

then substitute in [1] we have

C = 2 \cdot 3.14 \cdot 125

Simplify:

C = 785 m

Therefore, the circumference of a circle is 785 m
