Answer 2

Answer:

D. Yes, he has enough tiles. He needs only 4,256 tiles and will have 144 left over.

Step-by-step explanation

Multiply the width by the length 38x112= 4,256

He has 4,400 tiles and only needs 4,256

4,400- 4,256= 144 left over tiles

4x − 3/3=7

Solve for x.

Answers

In the case that this is (4x - 3)/3 = 7, we would solve it like:

4x - 3 = 21
4x = 24
x = 6

In the case this is 4x - (3/3) = 7, we would solve it like:

4x - 1 = 7
4x = 8
x = 2

Final answer:

To solve the equation 4x - 3/3 = 7 for x, follow the steps below: add 3/3 to both sides to eliminate the fraction, simplify the right side, and divide both sides by 4 to isolate x. The solution is x = 2.

Explanation:

To solve the equation 4x - 3/3 = 7 for x, we will follow the steps below:

Add 3/3 to both sides of the equation to eliminate the fraction. This gives us 4x = 7 + 3/3.Next, simplify the right side of the equation. 7 + 3/3 is equal to 7 + 1, which is 8.Now, divide both sides of the equation by 4 to isolate the variable x. This gives us x = 8/4, which simplifies to x = 2.

So, the solution to the equation 4x - 3/3 = 7 is x = 2.

Answers

Final answer:

To solve for y in the equation 6x = 7 - 4y, isolate the y-term by subtracting 7 and dividing by -4. When x = -2, y = 15/4.

Explanation:

To solve for y in the equation 6x = 7 - 4y, we can start by isolating the y-term. First, subtract 7 from both sides of the equation to get 6x - 7 = -4y. Then, divide both sides by -4 to isolate y and change the sign, giving us y = -6x/4 + 7/4. To find the value of y when x = -2, we substitute -2 into the equation:

y = -6(-2)/4 + 7/4 = 3 + 7/4 = 3 3/4 = 15/4

224 7/10 in decimal form

Answers

224 7/10

One way to change this into a decimal is first changing the mixed fraction into an improper fraction. This can be done by multiplying the whole number (224) by the denominator (10) and then adding the numerator (7) to that number, and make sure to keep the denominator (10) the same.
224 7/10 = 2247/10
Then all you do is division or input it into a calculator to get the answer.
2247/10 = 224.7

Another way to do it is first look at the fraction (7/10). 7 out of 10, this would look like 0.7. 1 out of 10 is 0.1, 10 out of 10 is 1.0, etc. So now that you know the fraction is 0.7, all you do is add the whole number (224) to it, and you get:
224 + 0.7 = 224.7

Either way, the answer will be 224.7.

The fraction 2247/10 can be expressed in decimal form as 224.7.

To express the fraction 2247/10 in decimal form, we perform long division to divide the numerator by the denominator.

Dividing 2247 by 10, we obtain a quotient of 224 with a remainder of 7, The quotient represents the whole number part of the decimal, while the remainder becomes the decimal part.

Adding the decimal point, we can write the result as 224.7. So, 2247/10 as a decimal is 224.7,

This means that if we divide 2247 into 10 equal parts, each part represents 224.7 units,

Therefore, the decimal representation of 2247/10 is 224.7.

The ratio of free throws made to free throws tried is 0.75 for a professional basketball player. Last year, the player tried 16 free throws. Use pencil and paper. Explain how you can find the number of free throws the player made. Then answer the question below.

Answers

.75 is 75% which is also 3/4 or three-quarters. They all mean the same thing. That means he makes 3 out of every 4 shots.
If he shot 16 times he made 12 shots because:
16 X (3/4) = 12

Final answer:

To find the number of free throws a professional basketball player made, multiply the total attempts by the success ratio. For example, attempting 16 free throws with a 0.75 success rate results in 12 made shots.

Explanation:

Ratio of free throws made to free throws tried: 0.75 for a professional basketball player.

To find the number of free throws made: Multiply the total number of free throws attempted by the ratio of successful shots. For example, if the player attempted 16 free throws, the number made would be 16 x 0.75 = 12.

Answer: The player made 12 free throws.
