A science class has a ratio of 3 boys and 2 girls. Can there be 24 students in the class?

guajiro [1.7K]

Answer:

Let 3x be the number of boys

Let 2x be the number of girls

3x + 2x = 24

5x = 24

x = 4.8

3(4.8) = 14.4 boys

2(4.8) = 9.6 girls

There can't be 24 students for a ratio of 3 boys and 2 girls, because there can't be 14.4 boys and 9.6 girls, it has to be an exact number, otherwise it wouldn't make any sense.

For example, you and I are both 1 person, we can't be half a person or 0.6 of a person, only 1.

The company wants to print 8000 newspapers daily. How many magazines at most can the company print daily with the remaining numb

taurus [48]

Answer:

Option A.

The company can print $800$ magazines at most

Step-by-step explanation:

Let

N------> the number of newspapers

M------> the number of magazines

we know that

$0.5N+2.5M\leq 6,000$

For $N=8,000$

Substitute the value of N in the inequality and solve for M

$0.5(8,000)+2.5M\leq 6,000$

$4,000+2.5M\leq 6,000$

$2.5M\leq 6,000-4,000$

$2.5M\leq 2,000$

$M\leq 800\ magazines$

What is the following quotient? StartFraction RootIndex 3 StartRoot 60 EndRoot Over RootIndex 3 StartRoot 20 EndRoot EndFraction

FrozenT [24]

Answer:

$\sqrt[3]{3}$

Step-by-step explanation:

We are required to simplify the quotient: $\dfrac{\sqrt[3]{60} }{\sqrt[3]{20}}$

Since the <u>numerator and denominator both have the same root index</u>, we can therefore say:

$\dfrac{\sqrt[3]{60} }{\sqrt[3]{20}} =\sqrt[3]{\dfrac{60} {20}}$

$=\sqrt[3]{3}$

The simplified form of the given quotient is $\sqrt[3]{3}$ .
