A 42%
B 52%
C 58%
D 50%
Answer:
42%
Step-by-step explanation:
1) so out of the 50 girls surveyed, only 21 students played in the league. We can write this as 21/50
to convert this into percentage multiply by 2 on both sides:
21*2=42
50*2=100
42/100=42%
42% of girls played in the league

A bag contains 5 red marbles, 4 white marbles, and 5 blue marbles. Find P(red and blue).
Answer:
5/7
Step-by-step explanation:
The total number of marbles is 5+5+4 = 14
P(red and blue) = number of red and blue / total
=5+5 / 14
= 10/14
= 5/7

The line plot below shows the number of kilometers Carson biked each day for 14 days. Does one measure describe the data better than the other? Explain
Answer:
It depends on the description you want to make. If you want to describe how separate is the data, then you would use a variation measure like a standard deviation which will compare each data with the mean.
On the other hand, if you want to measure how close the data is, then you would use central measures, like the mean or median, that will tell you the central value the whole data is pointing to.
Therefore, there's no bettter measures, it always depends on what aspect you want to highlight about the data set.

What is the area of this figure
180 square inches
190 square inches
45 square inches
96 square inches
Answer 190 square inches
Step-by-step explanation:
If there wasn't a piece cut off of the rectangle, you would multiply 22 by 15 because those are the side lengths. However, there is a piece missing so it will not have a great of an area. On the left side, it says that the width is 8 because part of the side is cut off. On the other side, it says 22. This shows that 14 inches is cut off. So width of the missing piece is 14. Then you need to find the length. On the bottom. It says the length is 5 where the top says 15. That shows that 10 inches are missing. That means the missing side is 14x10 which is 140 square inches. If the rectangle was a whole, it would be 330. You subtract 140 from that and it makes 190 square inches.
Answer:
190 square inches.

How do you write 3.0 × 10^2 in standard form?
Answer:
300
Step-by-step explanation:
First you would find 10^2, which is 100. Then you just multiply 100 by 3.0 and get 300 :)
Answer:
To write in standard form, we have to move the decimal point in 3.14 over 2 places to the left since our exponent is −2. This gives us our answer of 0.0314.

The half-life of a certain radioactive element is 35 hours. If there are 904 grams of this element, how much will be left after 70 hours? (please help I might fail Math.)
Answer:
226 grams
Step-by-step explanation:
The half-life of a radioactive substance is the time taken for half the quantity of the substance to decay such that the amount life after the given period of time is half the original quantity.
As such, given that the half-life of a certain radioactive element is 35 hours and there are 904 grams available, it means that after 35 hours,
Amount decayed = 1/2 * 904 grams
= 452 grams
Amount left = 904 grams - 452 grams
= 452 grams
After another 35 hours (now a total of 70 hours),
Amount decayed = 1/2 * 452 grams
= 226 grams
Amount left = 452 grams - 226 grams
= 226 grams

Jack has 20 unit cubes. How many rectangular prisms with different sized bases can he build with the cubes?
Answer:
Jack can form four rectangular prisms with 20 unit cubes.
Step-by-step explanation:
Number of unit cubes Jack has = 20
Factors of 20 = 1, 2, 4, 5, 10, 20
The possible dimensions of a rectangular prism that can be formed by these unit cubes may be,
1 × 1 × 20 (One cube at the base)
1 × 2 × 10 (2 cubes at the base)
1 × 4 × 5 (4 cubes at base in a single row)
2 × 2 × 5 (4 cubes at the base with 2 cubes in length and 2 cubes in width)
Therefore, Jack can form four rectangular prisms with 20 unit cubes.
factorise 2d^2-98 completely
Answer:
Hello,
2 (d + 7) (d - 7)
Step-by-step explanation:
2 d² - 98 = 2 (d² - 49) = 2 (d² - 7²)
a² - b² = (a + b) (a - b)
2 (d² - 7²) = 2 (d + 7) (d - 7)

Answer:
the answer is 12
Step-by-step explanation:
you basically have to divide 8 by 2/3 then you would get 12
8/1 / 2/3 kcf8/1 x 3/2= 24/224 divided by 2 = 122 2/3 Divided by 1/4
Find the quotient simplify if possible
Answer:
Step-by-step explanation:
make 2 2/3 into an improper fraction by multiplying 2 by 3 and adding to 2
8/3
8/3 divided by 1/4 is the same as 8/3 multiplied by 4/1 (just 4)

To finish a project, you need to paint the lateral surfaces of a cube with side length 2.5 inches. Find the area that you need to paint.
Answer:
[tex]25 in^2[/tex]
Step-by-step explanation:
We want to find the lateral surface area of the cube.
The lateral surface area of a cube is given as:
[tex]A = 4a^2[/tex]
where a = length of side of the cube
Therefore, given that the length of the side of the cube is 2.5 inches, the area you need to paint is:
[tex]A = 4 * 2.5^2\\A = 25 in^2[/tex]
Luke has 1/5 of a package of dried apricots. He divides the dried apricots equally into 5 small bags. Luke gives one of the bags to a friend and keeps the other four bags for himself.
What fraction of the original package of dried apricots did Luke keep for himself?
Answer:
4/25
First we have to divide 1/5 by 5. To do this we must follow the rules of dividing fractions which is switching the numerator and denominator of the second number/fraction, so 5 becomes 1/5. Next, we have to multiply the two fractions: 1/5 x 1/5= 1/25 (This is the amount of apricots in 1 bag). If we multiply that by 5, its going to 5/25 which is now 5 bags. 5/25 - 1/25=4/25 and that is our final answer.
