Answer:

Option C.

Step-by-step explanation:

Note: The question and options are not in correct form.

Let the correct question is "Consider the formula for the average velocity, v, of a moving particle. In the formula, d1 and d2 represent the distance traveled by the particle at times t1 and t2 respectively.

v = (d2 - d1)/(t2 - t1)

Which of the following equations is equivalent to the formula for velocity?

A. t1=v(d2-d1)-t2

B. d1=v (t2-t1)-d2

C. d2=v(t2-t1)+d1

D. t2=v(d2-d1)+t1 "

The given formula is

$v=\dfrac{d_2-d_1}{t_2-t_1}$

On cross multiplication, we get

$v(t_2-t_1)=d_2-d_1$

Add $d_1$ on both sides.

$v(t_2-t_1)+d_1=d_2-d_1+d_1$

$v(t_2-t_1)+d_1=d_2$

Since, $d_2=v(t_2-t_1)+d_1$ , therefore, the correct option is C.

1. Maritza is baking cookies to bring to school and share with her friends on her birthday. The recipr requires 3 eggs for every

olga_2 [115]

Solution 1:

The recipe for cookies requires 3 eggs for every 2 cups of sugar.

Applying unitary method here,

So for 1 egg sugar required will be 2/3 cups.

Now we have to find number of cups of sugar required for 12 eggs.

Sugar required for 12 eggs = (2/3) * 12 = 8 cups

But Maritza's mom bought only 6 cups of sugar.

So her mom is short of 2 cups of sugar.

Solution 2:

Hamza bought 8 gallons of brown paint.

If 1/4 of a gallon of white paint is mixed with 2 gallons of brown paint, he would get the shade of brown he desired.

Now we have to find quantity of white paint for 8 gallons of brown paint.

For 2 gallons of brown paint = 1/4 gallons of white paint required

For 1 gallon of brown paint = 1/8 gallons of white paint required

For 8 gallons of brown paint = (1/8)*8 gallons of white paint required

Answer : For 8 gallons of brown paint 1 gallon of white paint is required.
