830,000 is the more accurate estimate because it closer to the actual figure than 800,000

If 25 students took an exam and 4 of them failed, what percent of them passed?

lisabon 2012 [21]

If 25 students took an exam and 4 of the students that took the exam failed, what percent of the students passed?

To find out how many students passed, we can subtract 4 from 25 and we will get a difference of 21.

The fraction $\frac{21}{25}$ represents the number of students who passed the exam out of all the students.

To find out what percent of the students passed, we can turn $\frac{21}{25}$ into a percent.

21 ÷ 25 = 0.84

0.84 × 100 = 84%

Therefore, 84% of the students who took the exam passed.

ASAP!! Find the length of side x in simplest form with a rational denominator

lidiya [134]

Answer:

$x=\sqrt{14}$

Step-by-step explanation:

This triangle is a 45-45-90 triangle.

By using the image I posted, we can find x easily.

So, we have $\sqrt{7}$ as one of the sides.

They hypotenuse, which is x is just $\sqrt{7} \sqrt{2}$

Simplify and we get x = $\sqrt{14}$

A rectangular prism and a cylinder have the same height. The length of each side of the prism base is equal to the diameter of t

NARA [144]

Answer:

The rectangular prism has the greater volume

Step-by-step explanation:

Given

Prism:

$Length = Width = a$

$Height = h$

Cylinder

$Diameter = a$

$Height = h$

Required

Shape with greater volume

The volume of a rectangular prism is:

$Volume = Length * Base * Height$

So, we have:

$V_1 = a*a*h$

$V_1 = a^2h$

The volume of a cylinder is:

$Volume = \pi r^2h$

Where

$r = \frac{d}{2}$

$r = \frac{a}{2}$

So, we have:

$V_2 = \pi *(a/2)^2 h$

$V_2 = \pi *\frac{a^2}{4} h$

$\pi = 3.14$

So:

$V_2 = 3.14*\frac{a^2}{4} h$

$V_2 = \frac{3.14}{4} a^2h$

$V_2 = 0.785 a^2h$

So, we have:

$V_1 = a^2h$

$V_2 = 0.785 a^2h$

Both expressions have the same factor but different coefficient

The expression with greater coefficient has the greater volume

So, the $rectangular$ $prism \\$ has the $greater$ $volume$

Because: $1 > 0.785$

WHAT IS THE SOLUTION TO 5-2N= 17

ryzh [129]

N is equal to 11 because 5-2n=17 would be changed into 2n-5=17 because it would be -17 if it was the original problem so that is why
