Answer:

875 students are enrolled in this year's freshman class after the first week of classes.

Step-by-step explanation:

Last year, there were 950 students.

This year, the class is 10% smaller. So it's number of students is 100 - 10 = 90% of last year.

0.9*950 = 855

Initially, this year class had 855 students.

During the first week, 20 enrolled.

855 + 20 = 875.

875 students are enrolled in this year's freshman class after the first week of classes.

ki77a [65]

Answer:

She had $106.

Step-by-step explanation:

2(x+26)=264

Step 1: Simplify both sides of the equation.

2(x+26)=264

(2)(x)+(2)(26)=264(Distribute)

2x+52=264

Step 2: Subtract 52 from both sides.

2x+52−52=264−52

2x=212

Step 3: Divide both sides by 2.

2x/2=212/2

x=106

Imagine you are trying to maximize the calories you burn in a 60-minute workout you do a few times a week. Running burns 9 calor

amm1812

Running burns the most calories folwed by aerobic

so max out the most and min the least

most running
running has no limit, so see least

aerobic, aerobic has to be at most 30 (less than 30)

rowing has to be at least 15 mins
say row=15 mins

then you have 45 mins left
max out on running (minus 1 tho to do running)

so
44mins running 1 min run, 15min row
total calories=507 calories burned

the way to do it is
x=running minutes
y=aerobic minutes
z=rowing minutes

x+y+z=60
9x+6y+7z=max calories
x≥5
y≤30
z≥15
those are the equations
not sure what the objective function is

Josh has a collection of 110 comic books. Eighty-two of the comic books feature superheroes. What percent of the comic books fea

IceJOKER [234]

So,

Josh has 110 comic books total, and 82 of them feature superheroes. To find the percentage, just divide 82 by 110.

$\frac{82}{110} = \frac{2*41}{2*5*11} = \frac{41}{55}$

$\frac{41}{55}=0.7\overline{45}$

To convert to a percent, just move the decimal place two places to the left and add a percent sign.

$0.7\overline{45} --\ \textgreater \ 74.\overline{54}\ percent$

Rounding, we get:

75%

So about 75% of Josh's comic books feature superheroes.
