Answer 1

Answer:

Multiply $55 by 0.15

Step-by-step explanation:

To find what 15% of the $55 makes we use the following expression:

55 ÷ 100 × 15

We can first divide 55 by 100.

55 ÷ 100 = 0.55

And then multiply it by 15.

0.55 × 15 = $8.25

Or, we can simply multiply $55 by 0.15 as given in the second option.

$55 × 0.15 = $.25

As we can see from the results, both ways works.

Answer 2

mutiply $55 by 0.15 bc its a 15 percent

in a game, if you roll a 1 on a 6-sided number cube, you lose a turn.
(a) What is the probability that you roll a 1? Explain your reasoning.
(b) What is the probability that you either roll a 1 or do not roll a one? Explain your reasoning.
(c) What is the probability that you don't roll a 1? Explain your reasoning.

Answer:

Answers

(a) The probability of rolling a 1 on a 6-sided number cube is 1/6. There is only one way to roll a 1, and there are six possible outcomes.
(b) The probability of rolling a 1 or not rolling a 1 is 1. There are only two possible outcomes, and one of them must occur.
(c) The probability of not rolling a 1 is 5/6. There are five ways to not roll a 1 (rolling a 2, 3, 4, 5, or 6), and there are six possible outcomes.

Answer:

(a) The probability of rolling a 1 on a 6-sided number cube is

1/6

. This is because there is 1 outcome that results in a 1 (rolling a 1) and there are 6 total possible outcomes.

(b) The probability that you either roll a 1 or do not roll a 1 is 1. This is because there are no other possible outcomes. You either roll a 1 or you don't.

. This is because there are 5 outcomes that do not result in a 1 (rolling a 2, 3, 4, 5, or 6) and there are 6 total possible outcomes.

Earl made a 1/2 pan of brownies using 2/3 cup of sugar how much. sugar will it take for a whole pan of brownies

Answers

If Earl made a 1/2 pan of brownies using 2/3 cup of sugar, we can use a proportion to find out how much sugar he will need for a whole pan of brownies.

Let's call the amount of sugar needed for a whole pan of brownies "x". Since a whole pan is twice the size of a half pan, we can set up the proportion:

1/2 pan / 2/3 cup sugar = 1 whole pan / x cups sugar

To solve for x, we can cross-multiply and simplify:

1/2 pan * x cups sugar = 2/3 cup sugar * 1 whole pan
x/2 = 2/3
x = (2/3) * 2
x = 4/3

Therefore, Earl will need 4/3 cups of sugar for a whole pan of brownies. This can be simplified to 1 and 1/3 cups of sugar

Answer:

4/3 Cups of Sugar

A salesperson uses a circle graph to represent shoe sales for one year. The central angle for the portion of the graph that represents running shoes measures 80°. If 200 running shoes were sold, how many shoes were sold?

Thanks! :)

Answers

Answer:

900. Give Braylist

Step-by-step explanation:

I'm right

To solve the problem, we can use proportions. Since the central angle for running shoes is 80 degrees, we know that the ratio of running shoes sold to total shoes sold is 80/360. This is because the total number of degrees in a circle is 360. Therefore, we can set up the proportion:

80/360 = 200/x

where x is the total number of shoes sold. Solving for x, we get:

x = (360 * 200)/80

x = 900

Therefore, the total number of shoes sold is 900.

Answer:

105 square inches

Step-by-step explanation:

area of a triangle = 1/2( base * height)

The base is 5 and the height is 8.

= 1/2 ( 5 *8)

= 1/2(40)

= 20

The area of each triangle = 20 sq inches

So 4 triangles x 20 sq inches each = 80 sq inches.

The area of the square is 5 x 5 = 25 sq inches.

Add them together.

80 + 25 = 105 square inches

Step-by-step explanation:

If E is the amount of energy that each full set of panels produces, then ...

3 of james's 5 panels produce 3/5E

4 of Ben's 6 panels produce 4/6E

We can compare these fractions when they have a common denominator.

3/5E = 18/30E . . . . energy from James's panels

4/6E = 20/30E . . . energy from Ben's panels

18/30 < 20/30 . . . . so Ben's panels are producing more energy

If James has 5 and and Ben has 6, that’s 12 then divide that by 3 and it’s 4. Ben

Answers

The area is 198.5cm sq

The shape can be divided into a circle of

5cm radius

as diameter is 10cm

radius = d/2

length is 22-( 2×5) 12cm

and breadth is 10cm

The area of the circle is pi(r square)

which is 3.14×25

From the question, we have the following parameters that can be used in our computation:

Description by county:

Land areas won by Republicans is greater than those won by Democrats.

Description by state:

Democrat winner = approximately half

Republican winner = approximately half

The above means that

The republican won the election

This is because;

When calculated by states, they have the same proportionWhen calculated by county, Republican hold more votes

Hence. The Republicans won the most electoral votes in the election.

Answers

Answer:

13/35

Step-by-step explanation:

Probability determines the likelihood of an event happening.

Since we are not looking at the 7th Graders list, let's focus on the list on 8th Graders.

Given:

8th grade

Guitar - 4 students

Bass - 13 students

Drums - 13 students

Keyboard - 5 students

Since we are trying to find the probability of an eighth grader chosen at random to play the drums, let's turn our attention to how many students actually play the drums.

13 students play the drums.

In order to find the probability of a student chosen at random who plays the drums, we have to find how many students play the drums (which we already found) out of the total amount of students there are in that grade/section. Summing up, probability = the amount of favorable cases divided by the amount of possible cases.

Let's use this formula:

P(A) = n/N

Where "P(A)" stands for the probability of the event "A". And "n" represents the # of favorable outcomes and "N" represents the # of total possible outcomes.

Let's find how many students are in 8th grade now by adding all the people who play the musical instruments together:

4 + 13 + 13 + 5

= 35 possible outcomes.

Now let's plug it into the formula:

P(A) = n/N

P(A) = 13/35

13/35 can simplify any further.

The probability of choosing a student who plays the drums at random is 13/35.
