Answer:

one solution.

Step-by-step explanation:

The given equation is |x+7|=0

When we eliminate the absolute sign then we'll get below two equations

x + 7 = 0 and x + 7 = -0

Let us solve these two equations.

x + 7 = 0

Subtract 7 to both sides

x = -7

Now, solve the second equation

x + 7 = -0

Subtract 7 to both sides

x = -0-7

x=-7

Therefore, the solution is x = -7 and hence, we can conclude that the equation |x+7|=0 have only one solution.

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.

Crank

The volume of given cube is: $4.29 * 10^{-5}$ cubic meters

Step-by-step explanation:

Volume of a cube is given by:

$V = a^3$

Given

Edge of the cube = $3.5*10^{-2}$

Putting the value of edge

$V = (3.5*10^{-2})^3\\V = 42.875 * (10^{-2})^3\\V = 42.9 * 10 ^{-2*3}\\V = 42.9 * 10^{-6}\\V = 4.29 * 10 * 10 ^{-6}\\V = 4.29 * 10^{-5}\ cubic\ meters$

The volume of given cube is: $4.29 * 10^{-5}$ cubic meters
