Our principal has to travel from one city to the next city at an average speed of 50km/hr. Compute for the distance between 2 ci

astra-53 [7]

Answer:

The answer is false or "impossible"

Step-by-step explanation:

Heres why I say this:

If the “average speed” in one hour make the car travel 50km, it means the speed could not be constant. So, it could be 90km/h during the first 30 minutes and 10km/h during the second 30 minutes. If this is the case, for example, in the next 12 minutes after the first hour, the car could be traveled 18km at 90km/h, completing 50 + 18 = 68km. The tricky word “average” makes it impossible to answer. Good try, but no cigar.

A cafeteria manager needs to know how many apples and bananas to to order. He asked students to choose either an apple or a bana

shusha [124]

Answer:

Step-by-step explanation:

The answer is easy to find if we use the cross-multiplication method.

We know 7 students out of 10 picked apples, then 3 out of 10 picked bananas.

We know the number of people who picked apples.

$\frac{apples}{bananas} = \frac{7}{3} = \frac{84}{x}$

We just have to isolate x, this way and solve the problem:

$\frac{7}{3} = \frac{84}{x}$

becomes

$x = \frac{84 * 3}{7} = \frac{252}{7} = 36$

So, 36 students picked bananas as their favorite fruit.

Step-by-step explanation:

2/5 x = 6/5

Multiply each side by 5/2 to isolate x

The sale price of a spring break vacation package was $209.99 the travel agent said by booking early you saved $20.00. Find the

prisoha [69]

Answer:

$\%\ decrease = 9.52\%$

Step-by-step explanation:

Given

$Sales\ Price = \$209.99$

$Saved = \$20.00$

Required

Determine the %decrease

First, we need to determine the amount paid

$Amount = Sales\ Price - Amount\ Saved$

$Amount = \$209.99 - \$20.00$

$Amount = \$189.99$

The percentage decrease is the calculated as follows:

$\%\ decrease = -100\% * \frac{Final - Initial}{Initial}$

In this case;

$Initial = Sales\ Price = \$209.99$

$Final = Amount\ Paid = \$189.99$

So; we have:

$\%\ decrease = -100\% * \frac{189.99 - 209.99}{209.99}$

$\%\ decrease = -100\% * \frac{-20}{209.99}$

$\%\ decrease = 100\% * \frac{20}{209.99}$

$\%\ decrease = \frac{2000\%}{209.99}$

$\%\ decrease = 9.52426306015\%$

$\%\ decrease = 9.52\%$ (Approximated)

dalvyx [7]

Given:

Elise is making punch for the party that requires 2 parts of fruit juice for every 5 parts of ginger ale.

To make the punch, she uses 18 ounces of fruit juice and 3 containers of ginger ale.

To find:

The number of ounces in each container of ginger ale.

Solution:

Let n be the number of ounces in each container of ginger ale.

According to the question, the ratio of fruit juice and ginger ale is 2:5. it means,

$\dfrac{\text{Fruit juice}}{\text{Ginger}}=\dfrac{2}{5}$

$\dfrac{18}{\text{Ginger}}=\dfrac{2}{5}$

$5\times 18=2\times \text{Ginger}$

$90=2\times \text{Ginger}$

Divide both sides by 2.

$45=\text{Ginger}$

So, ginger required for punch is 45 ounces.

Number of containers = 3

Number of ounces in each container of ginger ale = n

Number of ounces in 3 containers of ginger ale = 3n

Now,

$3n=45$

Divide both sides by 3.

$n=15$

Therefore, 15 ounces are in each container of ginger ale.
