Answer 2

Answer:

The missing angle is 20°

Step-by-step explanation:

If the bags can either be given or not, each bag can assume one of two states. In order for there to be 200 possible combinations of items in one of two states, there must be at least log2(200) = 7.64 items. The minimum number of bags is x = 8.

There are 1420 students enrolled at Senn. If 60% of these students walk to school, how many students are walking to school?

I need an explanation also :)

Answers

Answer:

852 students walking to school

Step-by-step explanation:

Lets start with a simple example so you can get it

if 60% of 100 students walk to school that means

60 students walk to school... right??

so lets simplify it more that means you have multiplied 100 (students) by 60%

or [tex]\frac{60}{100}[/tex]  (note: you can say that 60% is equal to [tex]\frac{60}{100}[/tex] )

so the problem told 60% of 1420 students walk to school that means we should

do this:     [tex]1420*\frac{60}{100} = 852[/tex]

Answer:

852 walk to school

Step-by-step explanation:

i got this because i divided the 1420 into 10 which became a 142, multiply by 6 and you get 852

also you could

it is really simple also, all you have to do is multiply the number of student, S times the precent of students who walk, so s times w, which is 60 precent turend into .6 precent so 1420 x .6

Solve the proportion 3/x+1 = 1+2

Answers

Answer:

x = 5

Common denominator of 3/x+1 to 1/2

If the numerator is 3 times, then so is the denominator in a proportion.

3/1=x+1/2

x+1 must equal 6 for the proportion to be equal to 1/2.

6-1=5, so x is 5.

Tickets for a school jazz concert were sold before the concert and at the door. After reviewing ticket sales, the band director found that 80 fewer tickets were purchased at the door than before the concert. A total of 520 tickets were sold. Let d represent the number of tickets sold at the door and b represent the number of tickets sold before the concert. Latifa wrote the following system of linear equations to find the number of each type of ticket sold:

d + b = 520. d minus 80 = b.

What is Latifa’s error?
Latifa should have written the first equation as d minus b = 520.
Latifa should have written the second equation as d + b = 80.
Latifa should have written the first equation as b + 80 = 520.
Latifa should have written the second equation as d + 80 = b.

Answers

sum is an answer to an addition problem, so we have to add 43 and z. z+43=72.98

Subtract 43 on both sides.

z=29.98

hope it helps

Answer:

43 + z = 72.98

Step-by-step explanation:

Sum meaning add the two (or more numbers together) we get 43+ z = 72.98

If you're trying to find "z" simply subtract 43 from 72.98 to get 29.98 as z

Answers

Answer:

Option D

Step-by-step explanation:

Formula to use: V=[tex]\frac{1}{2}(b*a)*h\\[/tex]

b=base of triangle   a=altitude of triangle  h=height of prism

Doing [tex]\frac{1}{2}(b*a)[/tex] is essentially finding the area of the triangle and after multiplying by h will give you the volume of the triangular prism.

Solve: V = [tex]\frac{1}{2}(3*3)*7[/tex]  or option D

Ps. Altitude is perpendicular or 90 degrees to the side I used for the base, so it wouldn't be option C.
