Answer:

21 & 22

42.25 ÷ 2 = 21.125.

21.125 rounded to the two nearest whole numbers is 21 and 22.

21 and 22 are the closest integers to 21.125.

The answer is 21 and 22.

Hope it helps!

Answer: I lie between 6 and 7.

Step-by-step explanation:

If the number multiplied by itself gets the product 42.25 then if I find the square root of the number 42.25, I will get the number.

So find the square root of 42.25

$\sqrt{42.25}$ = 6.5

This means the number will lie between 6 and 7.

GEOMETRY find the angle of PRQ NO LINKS!!

anzhelika [568]

Answer:

Step-by-step explanation:

Remark

This is a really good question to know the answer to. <PRQ = 1/2 POQ (the central angle. )

The central angle for this question is 110o. So any angle that has its vertex on the circumference is 1/2 110 = 55. The central angle and the angle on the circumference must be related as they are as this question is. (Both are on the same side of PQ which is not drawn but you can draw it).

Carrie can inspect a case of watches in two hours. Jerry inspects a case in five hours. After inspecting a case for a half an ho

masha68 [24]

Write the hours as ratio

Carrie : Jerry
2 : 5

Put this ratio in words, we say 'for every two hours Carrie takes to inspect a case, Jerry would need 5 hours'

Carrie has done 30 minutes on a case before taking a break. It means Carrie has 1.5 hours left on the case if she was to continue it.

We need to work out the proportion of the time Jerry would take in comparison to 1.5 hours that Carrie would have taken.

First, we divide 2 by 1.5 ⇒ $\frac{2}{1.5}= \frac{4}{3}$

Then we divide 5 by 4/3 ⇒ $\frac{5}{4/3} = \frac{5*3}{4} =3.75$ hours

Jerry would have taken 3.75 hours to finish the rest of the case

Answer:

$\approx 0.482659$

Step-by-step explanation:

The experimental probability is the chance of an event happening based on data, or rather the experiment results, and not on a theoretical calculation. In essence, a theoretical calculation can be described by the following formula:

$\frac{desired}{total}$

However, the experimental probability can be described with the following formula:

$\frac{number\ of\ desired\ outcomes}{number\ of \ trials}$

The number of trials is the sum of the number of outcomes. In this case, the desired outcome is tails. Therefore, the experimental probability can be described using the following formula:

$\frac{tails}{total}$
