Zoey inflated 24 balloons for the high school dance. If Zoey inflated 15% of the total number of balloons at the dance, how many balloons are there total?
Answers
Answer:
Total number of balloons= 160
Step-by-step explanation:
Giving the following information:
Number of balloons inflated by Zoey= 24
Proportion of balloons inflated= 15%
To calculate the total number of balloons, we need to use the following formula:
Total number of balloons = Number of balloons inflated by Zoey / Proportion of ballons inflated
Total number of balloons= 24 / 0.15
Total number of balloons= 160

Answers
Step-by-step explanation:
step 1. the diagram is very unclear and should be redone
step 2. I'll assume 9r - 17 and 3r + 13 are vertical angles and are equal
step 3. 9r - 17 = 3r + 13
step 4. 6r = 30 or r = 5
step 5. I'll assume 4s - 3 and 7s - 24 are alternate interior angles and are equal
step 6. 4s - 3 = 7s - 24
step 7. 3s = 21 or s = 7.

c) The temperature at a football game and the amount of hot drinks sold
d) The number of people attending a ballgame and the length of the ballgame
el
Answers
Answer:
C
Step-by-step explanation:
I would say that if it were not outside you would tend to sell more drinks and / or if it were cold outside you would tend to sell less drinks
C - the temperature at a football game and the amount of drinks sold.
explanation
a child’s shoe size is not determined by age, but by genetics. yes children’s feet grow larger as they age, but the shoe size is not CAUSED by the age.
the amount of ice cream and sunscreen sold has no causation.
the temp at a football game and the amount of drinks sold is an example of a causal relationship. the amount of drinks sold is determined or caused by the temperature outside. more people will buy hot drinks if it is cold outside but if it’s not cold outside less people will buy hot drinks.
the number of people attending a ball game does not determine the length of the game.

The isotope Herodium-100 decreases by half every minute, Herodium-100 is there
isotope that gives a super hero their strength. Once the amount depletes to 4 ml, a
superhero becomes tired and need to leave the fight. If Mathman has 2000mL in his
body, when will he have to rest and replenish, rounded to the nearest minute?
Answers
Answer:
After about 9 minutes.
Step-by-step explanation:
We can write an exponential function to model the decay of Herodium-100.
We are given that it decreases by half every minute.
The standard exponential function is given by:
[tex]f(m)=A(r)^m[/tex]
Where A is the initial amount, r is the rate, and m is the rate (in this case, in minutes).
Mathman initially has 2000 mL of Herodium-100. Therefore, A = 2000.
And since it decreases by half every minute, r = 1/2. Thus:
[tex]\displaystyle f(m)=2000\Big(\frac{1}{2}\Big)^m[/tex]
Mathman needs to rest when the Herodium-100 levels drop to 4 mL. Therefore, we can substitute 4 for f(m) and solve for m:
[tex]\displaystyle 4=2000\Big(\frac{1}{2}\Big)^m[/tex]
Solve for m. Divide both sides by 2000:
[tex]\displaystyle \frac{4}{2000}=\frac{1}{500}=\Big(\frac{1}{2}\Big)^m[/tex]
We can take the natural log of both sides:
[tex]\displaystyle \ln\Big(\frac{1}{500}\Big)=\ln\Big(\frac{1}{2}^m\Big)[/tex]
By logarithm properties:
[tex]\displaystyle \ln\Big(\frac{1}{500}\Big)=m\ln\Big(\frac{1}{2}\Big)[/tex]
Therefore:
[tex]\displaystyle m=\frac{\ln(1/500)}{\ln(1/2)}\approx 8.9657\approx 9\text{ minutes}[/tex]
Mathman will have to rest and replenish after 9 minutes.

The mean age of 5 people in a room is 39 years.
A person enters the room.
The mean age is now 36.
What is the age of the person who entered the room?
Answers
Answer:
fast multiply 5 by 39 to get the total age of the five people now as you are told those per 5 so imagine the six person being you if you enter you're going to add to their ages so they mean is going to be for six people so take the six people x their mean age now we have two different total ages for the five people and for the six people subtract the total age of the 5 from the 6th total ages to get the age of the person who entered the room if you don't understand please ask me and be willing to help
Answer:
The age of the person who entered the room is 21.
Step-by-step explanation:
Mean of 5 peoples = 39
i.e.
Sum / 5 = 39
Sum = 39 x 5
Sum = 195
Mean after one person enters the room = 36
Let x be the age of the new person.
Then
Mean = (Sum + x)/ 6
36 = (195 + x)/6
36 x 6 = 195 + x
216 = 195 + x
x = 216 - 195
x = 21

A basketball team scored 82 points in a game. The players made no free throws,and the number of two point field goals was 2 more than 5 times the number of three point shots. How many of each shot did they make?
Answers
Answer:
3 points = 6
2 points = 32
Step-by-step explanation:
Points scored = 82
Let
Number of 2 points goals = x
Number of 3 point goals = y
2x + 3y = 82 - - (1)
x = 5y + 2 - - - (2)
(1) Becomes :
2(5y + 2) + 3y = 82
10y + 4 + 3y = 82
13y = 82 - 4
13y = 78
y = 78/13
y = 6
x = 5y + 2
x = 5(6) + 2
x = 30 + 2
x = 32

An airline might first consider the average woman's hip breadth when designing seats. Why would the airline use women instead of men when determining the maximum width of an airline seat?
Answers
Answer:
Airlines would use women instead of men because women usually have wider hips compared to the average men. So if they give enough room for the average women, then there will be enough room for the average man.

Answer:
a) $2.40
b) $16.80
c) y = -2.40x +16.80
Step-by-step explanation:
a. Dylan's daily spending is the opposite of the slope of the line on the graph. That slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (4.8 -12)/(5 -2) = -7.2/3 = -2.4
Dylan spends $2.40 at lunch every day.
__
b. The y-intercept can be found from the formula ...
b = y1 -m(x1)
b = 12 -(-2.40)(2) = 16.80
Dylan's dad gives him $16.80 at the beginning of each week.
__
c. The slope-intercept equation is ...
y = mx + b
y = -2.40x +16.80

• Next, the triangle:
Formula: b•h/2
Add the 10 and 50, which is 60.
60 • 20 = 1200
1200/2 = 600 ft2
• For the circle:
Formula: π • r^2
The radius is 10ft
3.14 • 10^2
3.14 • 100 = 314 (Whole circle)
Since we need half of the circle, we divide by 2 to split them.
314/2 = 157 ft2
• Now add all together:
1000 + 600 + 157 = 1757 ft2

A baby dolphin is born into the ocean, which is a fairly cold environment. Water has a high heat conductivity, so the thermal regulation of a newborn dolphin is quite important. It has been known for a long time that baby dolphins' blubber is different in composition and quantity from the blubber of adults. Does this make the babies better protected from the cold compared to adults? One measure of the effectiveness of blubber is its "conductance". This value as calculated on 5 newborn dolphins and 6 adults dolphins (Dunkin et al. 2005).
Answers
Answer:
Yes
Step-by-step explanation:
Yes, the difference in composition and quantity from the blubber of baby dolphins in comparison to that of adults allows them to regulate and maintain their body temps much more efficiently. This in term allows baby dolphins to have a much higher probability of survival as opposed to if their blubber was the same as adults. Once they reach a certain age the composition begins to change since they are able to more easily adapt to their environment.
