How Do I Answer The Red Question?

Answer 1

Answer: who made this question I think you need to round 250 to the nearest whole number I’m not sure.

Step-by-step explanation:

Answer 2

Answer:

If I am reading this correctly, then the probability is \(\frac{6}{250}\), or in decimal form, 2.4%, which rounds to 2%.

Step-by-step explanation:

To solve probability problems, you need to make a fraction, with the denominator being the # of reinforcements (250) and the numerator being the # of soldiers with measles. (6, if I'm reading this correctly.) So, divide \(\frac{6}{250}\), which is 2.4%, and to the nearest whole number, that's 2%.

What is volume of a cylinder?

A cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases are normally circular in shape (like a circle) and the center of the two bases are joined by a line segment, which is called the axis.

The volume of a cylinder = πr²h

there are 7.48 liquid gallons in a cubic foot.

therefore in 1100 liquid gallons there will be 1300/7.48 = 173.7 ft³

147.1 = 3.14 × 2.6² ×h

147.1 = 21.2h

h = 173.7/21.2

h = 8.2ft(nearest tenth)

therefore the height of the tank is 8.2ft

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there

Answers

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

The price was $250. Now its 100 find the percentage change

Answers

Answer:

Step-by-step explanation:

The formula for percent change is

\(\frac{original-new}{original}*100\)

Therefore,

\(\frac{250-100}{250}*100=60\)%

Answer: 60%

Step-by-step explanation:250 - 100 = 150

150/250 = 60/100 = 60%

90° counterclockwise rotation
270° clockwise rotation
90° clockwise rotation
180° counterclockwise rotation

Determine the direction and degree of rotation used to create the image. 90 counterclockwise rotation

Answers

Answer:  90° clockwise rotation

Step-by-step explanation:

The rules for rotation are below:

90° clockwise rotation = (x, y)→(y, -x)

270° clockwise rotation = (x, y)→(-y, x)

180° counterclockwise rotation = (x, y)→(-x, -y)

90° counterclockwise rotation = (x, y)→(-y, x)

Let's take point B. Point B's coordinates are (3, -2). Point B' is (-2,-3). -x would be -3, and y stays the same.

Therefore, the answer is 90° clockwise rotation.

Give 1/2 a cup to a dog that weighs 25 lb

Answer: hope this helps ♡

\(\frac{5}{12}\) cups of dog food is recommended for a 25-pound adult dog.

Step-by-step explanation:

Unitary method: diving the number that you want to find out over the already known number. (just try to understand this lol)  :)

10 lb = ⅙ Or 0.1666666 cups

1 lb = ? cups

\(\frac{0.16}{10}\) = 0.01666666

1 lb = 0.01666666 cups

25 lb = 0.01666666 × 25 cups

25 lb = 0.416666667 Or \(\frac{5}{12}\) cups

(Or:      10lb= ⅙              20lb= ⅙+⅙ = \(\frac{2}{6}\)              5lb= ⅙ ÷ 2= \(\frac{1}{12}\) (10lb÷2)       25lb = \(\frac{1}{12}+\frac{2}{6}\) = \(\frac{5}{12}\) ≈ 0.416666667     (25=20+5)

the length of a basketball court is 94 feet by 50 feet. What would the dimensions be on a scale drawing using the scale 1in:5ft?

Answers

Answer: The width of the court needs to be 5.32 inches to maintain proper proportions.

Step-by-step explanation: We make the length of court 10 inches. Now let us convert 94 feet in the ratio of 10 inches. We can convert 94 feet into 10 inches by dividing the number 94 with 9.4

Therefore

Thus, divide 50 feet with 9.4 feet. So that you can maintain proper proportion in drawing.

Hence, the width of the court needs to be 5.32 inches to maintain proper proportions.
