Answer:

A)

Step-by-step explanation:

The problem stated that 20 percent got in honor roll.

The key word in the problem is randomly selected.

Out of a and b, it's simply crossing out one of them.

B doesn't make sense, since if you spun a spinner 100 times, each side would have a probability of 25 percent. And that's if you only used one of the parts as an odd number.

Another way to think of it is that there are 2/10 yellow marbles, and 8/10 red.

2/10=20 percent.

8/10=80

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

Term's are 7x and 5

Answer: 30 cups of soap

Step-by-step explanation:

Each car would take 2/3 cups of soap to be washed and there are 45 cars to be washed.

The number of cups needed is therefore:

= Cups required for one car * number of cars

= 2/3 * 45 cars

= 90/3

= 30 cups of soap

Answer:

88.8%

Step-by-step explanation:

1.) 30-18= 12 which is the number of member that had an average of 84

2.)Then multiply  12 times 84 = 1008

3.) You multiply 18 by 92 which equals 1656

4.)Add 1008 and 1656 together  and get 2664.

5.)Divide 2664 / 30 and you get the average of 88.8

Answer:

20.25 ounces

Step-by-step explanation:

We are given 2.25 ounces of cranberry poured into the container per second. We need to find is how much that is after 9 seconds. (Note: This is different from the 15.75 ounces of orange.) There are many ways to solve this question (e.g If 2.25 is 1, then multiply 2.25 and 9 = 20.25) Now to solve this let's set up fractions; let "x" be the variable;

[tex]\frac{1}{2.25}=\frac{9}{x}[/tex]

Apply fraction: if [tex]\frac{a}{b}=\frac{c}{d}\mathrm[/tex]  then [tex]a\cdot \:d=b\cdot \:c[/tex] (meaning cross multiply)

[tex]1\cdot \:x=2.25\cdot \:9[/tex]

Simplify

[tex]1 x = 2 . 2 5 \cdot 9 \\\\ x = 2 . 2 5 \cdot 9[/tex]

[tex]x = 2 . 2 5 \cdot 9\\\\x=20.25[/tex]

Therefore, there are 20.25 ounces of fruit pouch in the container after 9 seconds.

Question:

Plot two points that are 8 units from Point B and also share the same x-coordinate as Point B

See attachment for grid

Answer:

See attachment for plot

Step-by-step explanation:

See comment for complete question

From the attached image, we have:

[tex]B = (-6,0)[/tex]

Required

2 points that are 8 units away and on the same x coordinate

Let the two points be [tex]C\ and\ D[/tex]

The first condition is that; C and D must be on the same x coordinate as B.

So, we have:

C = (-6,_)

D = (-6,_)

8 units from B implies that we add or subtract 8 from the y coordinate of B.

So, we have:

[tex]C = (-6,0+8)[/tex]

[tex]D = (-6,0-8)[/tex]

[tex]C= (-6,8)[/tex]

[tex]D= (-6,-8)[/tex]

Answer:

11/320

Step-by-step explanation:

edge

The probability that the first student chosen is a senior and the second student chosen is a sophomore is equal to 11/320.

Probability is the likeliness of happening an event among all the events that are possible. It lies between 0and 1 and cannot be negative.

We have been given that the number of freshmen is 31, number of sophomores is 10, juniors is 17 and seniors be 22. Total number of persons be 31+10+17+22=80

let X denote person.

Probability that the first student is senior and second one is a sophomore=P(X=Senior)*P(X=Sophomore)

=22/80*10/80

=220/6400

=11/320

Hence the probability that the first student is senior and second one is a sophomore is 11/320.

Answer:

61 degrees

Step-by-step explanation:

Since one of the sides is 102, the opposite one will be the same.

so,

Answer:

2 kittens per crate

Step-by-step explanation:

The kittens in a room at an animal shelter are arranged in five crates, as shown.

The manager of the shelter wants the kittens distributed equally among the crates. How might that be done? How many kittens will end up in each crate?

Crate 1 = 2 kittens

Crate 2 = 1 kitten

Crate 3 = 4 kittens

Crate 4 = 3 kittens

Crate 5 = 0 kitten

Total kittens = 2 + 1 + 4 + 3 + 0

= 10 kittens

To distribute them equally among the crates, divide the number of kittens by the number of crates

Kitten per crate = number of kittens / number of crates

= 10 kittens / 5 crates

= 2 kittens per crate

Kitten per crate = 2 kittens per crate

Answer:

The measure of angle ABC is 36° ⇒ 1st answer

Step-by-step explanation:

Let us revise some important facts in the circle

The measure of the center angle is equal to the measure of its subtended arc

The measure of the inscribed angle is equal to half the measure of the central angle subtended by the same arc

The vertex of a central angle is the center of the circle and its sides are radii in the circle

The vertex of an inscribed angle is a point on the circle, and its sides are chords in the circle

In circle D

∵ D is the center of the circle

∵ A and C lie on the circle

- DA and DC are radii

∴ ∠ADC is a central angle subtended by arc AC

∴ m∠ADC = m of arc AC

∵ m∠ADC = (7x + 2)°

∵ m of arc AC = (8x - 8)°

- Equate them to find x

∴ 8x - 8 = 7x + 2

- subtract 7x from both sides

∴ x - 8 = 2

- Add 8 to both sides

∴ x = 10

Substitute the value of x in the measure of ∠ADC

∵ m∠ADC = 7(10) + 2 = 70 + 2

∴ m∠ADC = 72°

∵ AB and BC are two chords in circle D

∴ ∠ABC is an inscribed angle subtended by arc AC

∵ ∠ADC is a central angle subtended by arc AC

- By using the 2nd fact above

∴ m∠ABC =  m∠ADC

∴ m∠ABC =  × 72

∴ m∠ABC = 36°

The measure of angle ABC is 36 degrees

To get the required measure of m<ABC, we will use the theorem that states that the measure of the central angle is equal to the measure of its subtended arc and;

The vertex of a central angle is the center of the circle and its sides are radii in the circle

According to the given circle D

∠ADC is a central angle subtended by arc AC

m∠ADC = m of arc AC

m∠ADC = (7x + 2)°

m of arc AC = (8x - 8)°

Equate to find the value of x

8x - 8 = 7x + 2

x - 8 = 2

x = 10

Substitute the value of x in the measure of ∠ADC

m∠ADC = 7(10) + 2 = 70 + 2

m∠ADC = 72°

∠ADC is a central angle subtended by arc AC

m∠ABC =  0.5 × 72

m∠ABC = 36°

Hence the measure of angle ABC is 36 degrees
