Help ;/ 4.3 is 12.5% of what number?

Answers

Answer:

let x represent the number

12.5n/100=4.3

12.5n=4.3x100

12.5n=430

n= 430/12.5

n= 34.4

4.3 is 12.5% of 290.7
So...
X% times 4.3 equals 12.5
12.5 divided by 4.3 would give you 2.9069...
Now... it’s a percentage so multiply that by 100 and that would give you 290.69 or 290.7.

A circle is cut out of a piece of plywood that is 10in. square.Find the area of the circle and How many square inches of plywood are thrown away?

If you can solve this AND show your work you get brainlist.

Answers

Answer:

Area of the circle: 78.54in^2

Plywood thrown away: 21.46 in^2

Step-by-step explanation:

So the area of the square is 100 in. To find the area of a circle, you use the formula (pi)r^2 where r is the radius, in this instance it is 1/2 of ten which is 5. Then, plug it into the formula which will get you (rounded to the nearest hundred) 78.54in^2. Then, subtract from the total plywood area. Please mark brainliest :)

Two students are comparing scientific experiments to investigations. They came up with the following ideas.

Student A: Testing plant growth in different types of soils

Student B: Comparing the water level in a lake during different times of the year Which student gave an example of a scientific experiment? (5 points)

A: Student A because it requires experimental and control groups
B; Student B because it requires a hypothesis
C: Student A because it is preferably done in natural settings
D: Student B because it is preferably done across a long period of time

Answers

Answer:

A is the correct answer.

Step-by-step explanation:

In experiment we require a controlled variable which is the constant in example A that is the plant we intend to put into the soil. In example B there's no such thing as controlled variable, so we can't expect the position of the water level. the water level is so unpredictable since tides or tsunami might change the result.

Answer:

A

Step-by-step explanation:

Scientific experiments need to have an independent and a dependent variable. Scientists can manipulate the independent variable. A should be the correct answer because it mentions what I just said. All scientific experiments need to have a control and experimental group. Therefore, student A and the answer A are correct.

Four friends are told that the average (mean) of their grades for their favorite class is 83.75%.



Kevin got 94%, Elizabeth got 78%, and Katherine got 83%.

Tyler's grade was not revealed. What's Tylers grade?

Answers

Answer:

Tyler got 80%.

Step-by-step explanation:

Represent Tyler's average by t.

Then .94 + .78 + .83 + t

         -------------------------- = 83.75%

                         4

Multiplying both sides by 4, we get  2.55 + t = 3.35

                                                                       

so that t = 3.35 - 2.55 = 0.80

Tyler got 80%.

Kristen wants to ask the managers of the fast food restaurants in a large city "How do you retain employees?" What condition must be true to justify surveying only a sample of the managers instead of surveying the entire population of managers?

The population is small.

The population is diverse.

The population is not the target of the survey question.

The population is expensive and time-consuming to survey.​

Answers

I believe it is "The population is expensive and time-consuming to survey"

Answer:

Step-by-step explanation:

Surface area is the sum of the areas of all the sides.

The bottom side(the rectangle with dimensions 11.9 and 17.4): 11.9 * 17.4 = 207.06 * 1 = 207.06(because there is only one of this shape)

The rectangular sides(dimensions 10.5 and 14): 10.5 * 14 = 147 * 2 = 294 for both sides

The triangular sides(17.4 and 7): (17.4 * 7) / 2(because it a triangle) = 60.9 * 2 = 121.8(because there are two sides)
