1) At summer camp the ratio of boys to girls was 8: 5. If there were 32 boys, how many girls were
there?
21. Determine if the values in the table are
Answer:
20 girls.
Step-by-step explanation:
If 32 divided by 8 is 4, then 4x8= 32.
We use this equation to find out how many girls there are. 5x4 equals 20, so there are 20 girls at summer camp.
3 + 2 + (-8) -5 - 9 + 1 (-6) + 3 + 20

-16t^2+80t+4=100
Answer:
Step-by-step explanation:
Good job on creating a testable equation.
Maybe you need to know what to do with it.
If we can find a real solution or two, then the projectile will reach the 100 ft altitude. (I'm fairly certain it will given that high initial velocity)
If we cannot find a real solution, then the rocket will fail to reach the altitude goal.
-16t² + 80t + 4 = 100
we will want a zero on the right hand side, so subtract 100
-16t² + 80t - 96 = 0
we can simplify even further by dividing everything by -16
t² - 5t + 6 = 0
which can be factored
(t - 3)(t - 2) = 0
so either
t = 3 s
or
t = 2 s
So the projectile reaches the 100 ft level twice,
at two seconds after launch while rising and
at three seconds after launch while falling.
Lets see what happens when we set the goal a bit higher, say 108 ft
-16t² + 80t + 4 = 108
-16t² + 80t - 104= 0
-2t² + 10t - 13 = 0
not easily factored so let's use quadratic formula
t = (-10 ±√(10² - 4(-2)(-13))) / (2(-2)
t = (-10 ±√-4) / -4
As √-4 = 2i is an imaginary number, there are no real solutions and the projectile will not reach 108 ft.

How do I show my work for solving the radius of a circle if the area is 78.5 cm^2
(I already know the answer is 5 cm)
9514 1404 393
Answer:
radius = 5 cm
Step-by-step explanation:
The point of "show your work" is to have to do exactly that. If you know the answer to the problem, you are being requested to show how you got it. If you got it by using a web calculator, then show your input and its result.
__
If you worked the problem yourself, you probably did it by filling in numbers in the equation for the area of a circle:
A = πr²
78.5 = 3.14×r²
Dividing both sides by 3.14 gives the square of the radius:
78.4/3.14 = r² = 25
Taking the positive square root gives the radius:
r = √25 = 5
The area is in square centimeters, so the radius is in centimeters:
radius = 5 cm

Answer:
Step-by-step explanation:
Well, according to this graph,
The greatest growth should be between the years 3 and 4. the reason is because if you count (under the students column) how many numbers are increasing between the numbers. In this case, the largest (increasing) number of students was between 25 and 33. (i counted 7)
So, the completed sentence should be:
(please note the parenthesis is the drop down.. I am unsure of the answer choices in the drop downs though so they might be differently worded. this is just what i have gathered.)
The greatest growth was between years (3) and (4). The growth between those years was about (7 students). In the last dropdown it may just be 7 but in word form.

Step-by-step explanation:
Problema Solution
There were 155 people at the basketball game. Tickets for the game are $2.50 for students and $4 for adults. If the total money received for admission was $492.50, how many students and adults attended the game?
Answer provided by our tutors
let
s = the number of student tickets sold
a = the number of adult tickets sold
there were 155 people at the basketball game
s + a = 155
the total money received for admission was $492.50
2.50s + 4a = 492.50
by solving the system of equations
s + a = 155
2.50s + 4a = 492.50
we find
s = 85 students
a = 70 adults
A school carnival sold 24 early-admission tickets and 72 regular tickets. What percentage of the tickets sold were early-admission tickets? Write your answer using a percent sign (%).
Answer:
25%
Step-by-step explanation:
add both kinds of tickets first to get the total
24 early admission + 72 regular = 96 total tickets
then divide 24 early tickets by 96 total tickets to get the decimal, then multiply by 100 to get percent
[tex]\frac{24}{96} = 0.25 * 100 = 25[/tex]%

Membership at the YMCA costs $15 per month plus $80 to sign-up. Blink costs $29 per month but is free
to sign-up. After how many months will the two gyms cost the same amount?
Let months be x
[tex]\\ \sf\longmapsto 80+15x=29x[/tex]
[tex]\\ \sf\longmapsto 29x-15x=80[/tex]
[tex]\\ \sf\longmapsto 14x=80[/tex]
[tex]\\ \sf\longmapsto x\approx 6months[/tex]
Answer:
43 months in ymca including the $80 sign up fee is equal to 25 months in blink
Step-by-step explanation:
$725 divided by $29 =25 months
$ 725 - $80 sign up = $645 .
Now we divide this by $15.
$645 divided by 15= 43 months

9. Modeling Real Life A machine that
makes toy spinners is in operation for
8 hours each day. The machine makes
7,829 toy spinners in 1 day. About how many toy spinners does the machine make each hour?
Answer:
8 hours = 7,829 toy spinners
24 hours= x toy spinner
7829 / 24 x 8
2069 for one hour
Step-by-step explanation:
so your answer is this hope this helps good luck if it does not i am sorry
The number of toy spinners the machine make each hour is 2068.
Given that, the machine makes 7,829 toy spinners in 1 day.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Here,
8 hours = 7,829 toy spinners
24 hours= x toy spinner
Now, number of toys in one hour = 7829/(24×8)
= 2069.66
= 2069 per one hour
Therefore, the number of toy spinners the machine make each hour is 2069.
