for a class of 24,78% of students got a B or better on the tex How many students is this? Round to a wholenumber
natita [175]

Step 1

Use the ratio of the number to the percentage to get the required answer.

\frac{Total\text{ number of students}}{\text{The required number of students}}=\frac{Total\text{ percentage of the class}}{\text{Given percentage}}

Where,

\begin{gathered} \text{The total number of students = 24} \\ \text{The required number }of\text{ students= x} \\ \text{The total percentage of the class = 100} \\ \text{Given percentage = 78} \end{gathered}

Step 2

Get the required answer

\begin{gathered} \frac{24}{x}=\frac{100}{78} \\ 100x=24\times78 \\ 100x=1872 \\ \frac{100x}{100}=\frac{1872}{100} \\ x=\text{ 18.72} \\ \text{Hence} \\ x\approx19students\text{ rounded to a whole number } \end{gathered}

The number of students that got B or a better grade on the test = 19 students rounded to a whole number.

Find the value of x and y
Aleks04 [339]

Answer:

x=30

y=17

Step-by-step explanation:

We know that 6x+9 = 129  since they are vertical angles

6x+9 = 129

Subtract 9 from each side

6x+9 -9 =129-9

6x = 120

Divide by 6

6x/6 =120/6

x = 20

3y+129 =180  since they make a straight line and straight line are equal to 180 degrees

3y+129 =180

Subtract 129 from each side

3y+129-129=180-129

3y = 51

Divide by 3

3y/3 = 51/3

y = 17

For this figure, find the value of x.
DedPeter [7]
It is 78 because you can draw a transversal with the line that 79 is on, and 79+23+x=180. so 180-79-23=78 therefore 78=x
understand?
