a ramp measures 6 feet long. if the ramp is 12 inches tall, what is the horizontal distance that it covers?

svp [43]

We know that

1 ft--------> is equals to 12 in
the ramp is 12 inches tall----------> 1 ft tall
<span>A ramp measures------------------> 6 ft long
</span>
<span>applying the Pythagorean theorem
</span>c²=a²+b²
where
c-----> 6 ft long
a----> horizontal distance
b-----> 1 ft tall

a²=c²-b²------> a²=6²-1²-----> a²=35------> a=√35------> a=5.92 ft

the answer is
5.92 ft

Jeffrey is using a copy machine to make posters for a school play. The machine prints the posters at a constant rate. After 3 mi

jasenka [17]

Answer:

B: 11 minutes.

Step-by-step explanation:

So, we know that the machine prints at a constant rate.

After 3 minutes, the machine prints 108 posters.

So, let’s find the <em>unit rate. </em>We will divide the output over the input. So:

$108\text{ posters}/3\text{ minutes}=36\text{ posters/min}$

So, the unit rate of the machine is 36 posters per minute.

We can write an equation. If t represent the number of minutes and p represent the amount of posters, then:

$p=36t$

Gives the amount of posters p and t minutes.

We want to know how long it will take Jeffrey to make 396 posters.

So, we can substitute 396 for p and solve for t. Hence:

$396=36t$

Divide both sides by 36:

$t=11$

Therefore, it will take Jeffrey 11 minutes to make 396 posters.

What is the number of sides in a regular polygon when the measure of each interior angle is 162?

Ira Lisetskai [31]

Answer:

20

Step-by-step explanation:

interior angle + exterior angle = 180°

162° + exterior angle = 180° ( subtract 162° from both sides )

exterior angle = 18°

the sum of the exterior angles of a polygon = 360° , then

number of sides = 360° ÷ 18° = 20

You are researching the average emails received per day. You want to know how many employees you should survey if you want to kn

IrinaK [193]

Answer:

The value is $n =29 \ employees$

Step-by-step explanation:

Generally the number of employee to survey(sample size) is mathematically represented as

$n = [ \frac{z * \sigma }{E} ]^2$

Here E is the margin of error which is given as E = 47

So substituting 1.645 for z and 155 for $\sigma$

$n = [ \frac{1.645 * 155 }{47} ]^2$

=> $n =29 \ employees$
