Answer:

f(-8) = 104

Step-by-step explanation:

f(t) = t^2 - 5t

Let t=-8

f(-8) = (-8)^2  -5(-8)

       = 64 +40

       = 104

Mrs. Bendit’s 1st Block class has 28 students. There are 7 girls in the class. What percent of boys are in the class?
Gemiola [76]

Answer:

Boys: 75%

Girls: 25%

Step-by-step explanation:

Total: 28 Students: 100%

7 Girls in clas

28(total)-7 (girls)= 21 Boys in class

__________________

If we divide the amount  boys OR girls ( depending on which gender) after the toal and move the decimal to the right twice after dividing) we will get our answer.

Formula:

(Amount of Boy or girls) = x

X/28

So since we are trying to get the percentages of boys, we will replace X with the amount of boys

21/28 = .75 ( then move the decimal to the right TWICE) =  75  

Then you should get your percentages: 75%  Also if your lookings for girls percentages, you basically subtract 75 ( boys percentages) with the total percentages ( 100) then you should get your answer for the girls: 25%

monique has 3/4 of tissues. if she cuts half of those tissues how much did she cut? put the answer in a fraction and percentage(
skelet666 [1.2K]

The required fraction of the tissue she cut is 3 /8, and the percentage is 37.5%.

Given that,
Monique has 3/4 of tissues. she cuts half of those tissues

<h3>What is the fraction?</h3>

Fraction is defined as the number of compositions that constitute the Whole.

Here,
Let the number of tissue be x,
She has 3 / 4 of the tissues = 3 / 4 x
she cuts half of those tissues = 1 / 2 * 3 / 4 * x
                                             = 3/8x or 37.5% of x

Thus, the required fraction of the tissue she cut is 3 /8, and the percentage is 37.5%.

Write an equation in slope intercept form for <br> the given slope.<br> (5,9).(6,8)
vovangra [49]

<u>Answer: </u>

The equation in slope intercept form for (5,9) and (6,8) is y = 3x-10

<u>Solution: </u>

Given that (5,9) and (6,8)

Here, x_{1}=5 ; y_{1}=5 ; x_{2}=6 ; y_{2}=8

We know the slope of an equation is given by y = mx+c

To find the value of m, we use the below given formula

\mathrm{m}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Substituting the values we get,

\mathrm{m}=\frac{8-5}{6-5}

m = \frac{3}{1}

m = 3

Putting the value of m in the slope intercept form we get,

y = 3x+c

To find the value of c, we substitute the value of x and y from any two given point. Let’s take x = 5 and y = 5

5 = 3(5) + c

5 = 15 +c

5-15 = c

c = -10

Therefore the slope intercept equation becomes y = 3x -10
