I pretty sure it’s B because you have to undo what is being done to 4/5 which would be to divid it on both sides then all you have left is x + 20 so you should subtract it to get x by itself.

Answer:

I think it's 0.046

Step-by-step explanation:

Change the divisor 7.56 to a whole number by moving the decimal point 2 place to the right.Then move the decimal point in the dividend the same, 2 places to the right.

We then have the equations

35÷756=0.046

0.35÷7.56=0.046

Both calculated to 3 decimal places

The following linear equation represents the line of best fit for the following scatter plot

y=0.15x-1.5

Use the equation to answer the following questions. Predict the amount of home runs a player would have if they hit 200 times.

A) 25 home runs
B) 1,366 home runs
C) 28.5 home runs
D) 30 home runs

Answers

Answer:

C) 28.5 home runs

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

y = home runs

x = hits

[Best Line of Fit] y = 0.15x - 1.5

We can use this to predict the average of the scatter plot.

hits = x = 200 times

Step 2: Solve for y home runs

Substitute [BLF]:                     y = 0.15(200) - 1.5Multiply:                                  y = 30 - 1.5Subtract:                                 y = 28.5

Remember that this is only a prediction. Actual data can vary. The best line of fit tells us that if a player hits 200 times, we would get approximately 28.5 home runs.

Answer:

[tex]\huge\boxed{\text{(C) 28.5 home runs}}[/tex]

Step-by-step explanation:

If we are given the equation to this graph, we need to substitute a value in to get the output of the function.

Since the question is asking us how many home runs a player will earn if they hit 200 times, and we know that the x value is the number of hits, we can substitute 200 into the equation as x and find the value of y.

[tex]y =0.15x-1.5[/tex] [tex]y=0.15\cdot 200-1.5[/tex] [tex]y=30-1.5[/tex] [tex]y=28.5[/tex]

Therefore, 28.5 home runs would be scored with 200 hits.

Hope this helped!

A gift shop sells fruit baskets that each contain 4 apples and 3 oranges. If the shop owner orders 24
apples and 20 oranges, some fruit will be leftover. How should the owner adjust the order so there is no fruit left over? Explain.

Answers

6 baskets apples and 6 basket oranges.
Step-by-step explanation:
Divide 24 to 4
Divide 20 to 3 (remainder 2)

Owner should adjust the order in the equal multiple number of both 4 apples and 3 oranges so that there is no fruit leftover.

What is multiple of number?

The multiples of numbers are all the numbers that are the product of number and any other number.

A gift shops sells fruit baskets that each contain 4 apples and 3 oranges.

To adjust the order so that there is no fruit leftover, we have to order in multiples of  4 apples and 3 oranges.

e.g.  24 and 18 are the 6 multiples of 4 and 3 respectively.

If either of the numbers have different multiple or not have the same multiple fruits will be left.

Hence, Owner should adjust the order in the equal multiple number of both 4 apples and 3 oranges so that there is no fruit leftover.

when i solved i got -17/-1, but my calculator says it's 17! i tried searching and it said to divide the fraction to get 17, but why do i have to divide? can someone please help me, thank u!

Answers

Answer:

17

Step-by-step explanation:

The first thing to do is plug in the numbers for the equation. Starting with:

[-20-(-3)]/(19-20)

When you answer that you simplify the answer to

(-20+3)/(19-20)

You answer what is in the parenthesis first.

(-17)/(-1)

After this step you simplify.

17.

The answer is seventeen because any number over 1 is just the number. For example, 3/1=3. The answer is positive because the negative in the numerator and denominator cancel eachother out. leaving the answer as 17.

The answer would be 17 if I’m correct

Clare's recipe for banana bread won't fit in her favorite pan. The pan is 8 1/2 inches by 11 inches by 2 inches. The batter fills the pan to the very top, and when baking, the batter spills over the sides. To avoid spills, there should be about an inch between the top of the batter and the rim of the pan. Clare has another pan that is 9 inches by 9 inches by 2 1/2 inches. If she uses this pan, will the batter spill over during baking?

PLEASE ANSWER CORRECT

Answers

Answer:

Solution

In order to find out how high the batter will be in the second pan, we must first find out the total volume of the batter that the recipe makes. We know that the recipe fills a pan that is 8.5 inch by 11 inch by 1.75 inches. We can calculate the volume of the batter multiplying the length, the width, and the height:

VV=8.5 in×11 in×1.75 in=163.625 in3

We know that the batter will have the same volume when we pour it into the new pan. When the batter is poured into the new pan, we know that the volume will be 9×9×h where h is the height of the batter in the pan. We already know that V=163.625 in3, so:

V163.625 in3163.625 in3163.625 in381 in22.02 in=l×w×h=9 in×9 in×h=81 in2×h=h≈h

Therefore, the batter will fill the second pan about 2 inches high. Since the pan is 3 inches high, there is nearly an inch between the top of the batter and the rim of the pan, so it will probably work for the banana bread (assuming that Leo is right that that an inch of space is enough).
