Owen has a mask collection of 300 masks. He keeps 63 of the masks on his wall. What percentage of Owen's mask collection does he keep on his wall?
Using the percentage concept, it is found that he keeps 21% of his mask collection on the wall.
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
In this problem, the parameters are a = 63 and b = 300, hence the percentage is given by:
[tex]P = \frac{63}{300} \times 100\% = 21\%[/tex]

Answer:
Marcia is not correct.
See explanation below.
Step-by-step explanation:
The terms are
2x²
4xy
8xy^4
The terms broken down into products of prime factors are:
2x² = 2 × x × x
4xy = 2 × 2 × x × y
8xy^4 = 2 × 2 × 2 × x × y × y × y × y
To find the GCF, we circle the common factors of the three terms (here we use bold type instead of circling.)
2x² = 2 × x × x
4xy = 2 × 2 × x × y
8xy^4 = 2 × 2 × 2 × x × y × y × y × y
The GCF is the products of the circled (bold) factors.
GCF = 2x
Marcia's answer is the Least Common Multiple.
For the LCM, you use all factors that are common and not common with the larger exponent.
LCM = 2 × 2 × 2 × x × x × y × y × y × y = 8x²y^4
Marcia's mistake is that she calculated the LCM instead of the GCF.
Answer:
Marcia is not correct.
The explanation is above.
Answer:
See below.
Step-by-step explanation:
2x^2, 4xy, and 8xy^4
She is incorrect.
The GCF is 2x.
She found the greatest term, rather than the greatest factor.

At a bowling alley, there is a flat fee of
$
5.00
to rent shoes. In addition, it costs
$
1.25
for each game bowled.
Which equation shows the total cost (
c
) for the number of games (
g
) one bowls?
Answer:
I don't see any answer options, but the total cost should be:
c = $5.00 + $1.25g
Step-by-step explanation:
Assuming that the cost is for one person playing g games, and that person needs to rent 1 pair of shoes, the cost should be:
c = $5.00 + $1.25g
When Juan got home from school, he worked on his homework for 45 minutes. Then, he took a break and had a snack for 35 minutes, and after that went to baseball practice for 1 hour and 55 minutes. He finished baseball practice at 6:05 p.m. What time did he get home from school? of
Answer:
2:50 p.m.
Step-by-step explanation:
After he got home, his activities were:
homework: 45 minutes
break & snack: 35 minutes
baseball practice: 1 hour 55 minutes
1 hour = 60 minutes
Total time of activities:
45 minutes + 35 minutes + 60 minutes + 55 minutes = 195 minutes
195 minutes = 180 minutes + 15 minutes = 3 hours 15 minutes
Now we subtract 3 hours 15 minutes for 6:05 p.m.
6:05
- 3:15
----------
We need to borrow 1 hour from 6 hours. 1 hour is 60 minutes. 6 hours becomes 5 hours. We add the 1 hour as 60 minutes to the 5 minutes.

Apply the distributive property to factor out the greatest common factor.
22c+33d =
Answer:
Step-by-step explanation:
First find the GCF of 22 and 33
22 = 2 * 11
33 = 3 *11
GCF = 11
Distributive property:a*(b+c)=(a*b) + (a*c)
22c + 33d = 11 * 2c + 11 * 3d
= 11*(2c + 3d)
-13 = -3h + 2 solve for h
Step-by-step explanation:
-13 = -3h + 2
3h - 13 = 2
3h = 15
h = 5
Answer:
-5
Step-by-step explanation:
-13 = -3h + 2 First, move the positive two (we get rid of a + by using a -)
-2 -2
-15 = -3h -3 is divided (opposite of multiplication is division)

-5 = h Now we have our answer :)
The table shows the distance a cyclist rides her bicycle over time. Is the rate of change in distance with respect to time constant? What does the rate of change represent?
Bike Riding Distance
Time
(minutes) Distance
Traveled (ft)
1 1120
2 2240
3 3360
4 4480
A. The rate of change is constant and represents a speed of 1120 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.
B. The rate of change is constant and represents a speed of 3360 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.
C. The rate of change is constant and represents a speed of 2240 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.
D. The rate of change is constant and represents a speed of 4480 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.
From the relationship between the distance and time, the rate of change is constant and represents a speed of 1120 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.
What is a linear equation?A linear equation is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let y represent the distance travelled by the bike after x minutes.
From the table:
Rate of change = (4480 - 1120) / (4 - 1) = 1120 ft/min
The rate of change is constant and represents a speed of 1120 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.

Find the distance covered by a car in 3x hours is 27x³ + 9x² - 3x Find the rate of the car. Show your solution.
Answer:
distance = 27x³ + 9x² - 3x , time = 3x ,
rate =?
[tex]distance = rate \times time \\ \\ rate = \frac{distance}{time} \\ \\ r = \frac{d}{t} \\ \\ r = \frac{27 {x}^{3} + 9 {x}^{2} - 3x}{3x} \\ \\ r = \frac{3x(9 {x}^{2} + 3x - 1) }{3x} \\ \\ r = 9 {x}^{2} + 3x - 1[/tex]
So; The rate of the car equal (9x²+3x-1)

A scientist uses the equation shown below to predict the future population of a species. In the equation, y represents the estimated population and trepresents the number of years.
y=150•4^t
Which number is closest to the value of y when t=3/2
Answer:
1200 i think
Step-by-step explanation:
i used a calculator since its hard for me to do mental math
question 2
(sorry i replied late i was doing some of my school work)
so you make A be equal to 5000 since you want to know when his account will be that much money sooo
5000 = 2000(1.07t)
you divide 2000 from both sides
5000/2000 = 1.07t
5/2 = 1.07t
now you have to isolate t to solve for it
soo divide 1.07 to both sides
5/2 / 1.07 = t
t is equal to about 2.34 or 2 years (depends on what it tells you to round to) in the calc t is 2.336448598
so in maybe 2 years he'll have 5000 dollars

If X = 6 cm and Z = 10 cm, what is the length of Y?
A. 8 cm
B. 8 cm
C. 10 cm
D. 6 cm
Answer:
If XYZ is a triangle, then Y = 8 cm
Step-by-step explanation:
X^2 + Y^2 = Z^2, by the Pythagorean Theorem.
Z, in this equation, represents the hypotenuse; the hypotenuse must be the longest side, and we can therefore eliminate C, 10 cm, without even beginning. Then, we may plug the given values in.
(6)^2 + Y^2 = 10^2
36 + Y^2 = 100
Y^2 = (100 - 36) = 64
Y = 8 cm
