3 =1

Answer:  In one baseball season, Peter hit twice the difference of the number of home runs Alice hit and 9. Altogether, they hit 27 home runs.

Step-by-step explanation:

Answer: C

Step-by-step explanation:

The equation that is correct is this one ⇒ (310 − 10) ÷ 15 = s

We know that there are 10 pieces left over, so we can subtract that from our total amount. (310-10)

Then, we know that the rest of the candy was given to s students, hence (310 − 10) ÷ 15 = s.

BONUS -To solve the equation:

(310 − 10) ÷ 15 = s

300 ÷ 15 = s

s=20

Good luck on your homework!

Answer:

Price of suit yesterday = $920

Step-by-step explanation:

We will assume the price yesterday was $P

The discount is 64%

64% as a decimal = 64/100 = 0.64

Discount amount in $ = 0.64 x P =0.64P

Sale price after discount = P - 0.64P = P(1-0.64) = P(0.36) = 0.36P

We are given that the sale price is $331.20

Equating the expression 0.36P we get

0.36P = 331.20

P = 331.20/0.36

P = 920

So the price yesterday was $920

Always good to have a check

If price yesterday was $920 and a discount of 64% is applied, the discount amount = 64% of $920

= 0.64 x $920

= $588.80

This is the amount of discount

Sale price = Marked Price - Discount amount

= 920 - 588.80

= $331.20

So everything tallies

Answer:

The sale price yesterday was $517.50

The problem states that the value of $331.20 is 64% of the price of yesterdays value. So we have to find out what multiplied by 0.64 is 331.20. To do this we can set up the equation:

331.20= %64 x p

331.20= 0.64 x p

We then have to divide both sides by 0.64

p= 331.20/0.64

p=517.50

The equation c = 0.6w is correctly represented by the graph.

Answer: 1/3

Step-by-step explanation:

(1,5) will be x1 (1) and y1 (5)

(4,6) wil be x2 (4) and y2(6)

knowing this, you plug in the numbers into the formula

6-5 = 1

4-1 = 3

m= 1/3

Answer: [tex]\frac{1}{3}[/tex]

Step-by-step explanation: It's actually pretty simple to find the slope. y2 is the second y point and y1 is the first y point (same goes for x). So in this case, y2 = 6, y1 = 5, x2 = 4, x1 = 1. So once you have that, you would do this: [tex]\frac{6-1}{4-1}[/tex] subtract both equations and you'd get: [tex]\frac{1}{3}[/tex]

Hope this helped you and use this for future reference!

Answer: H

Step-by-step explanation:

5packs each pack has 300. Each of those 300 weighs 9.9x[tex]10^{-3}[/tex]

so

5*300*9.9*[tex]10^{-3}[/tex]                I only multiplied the numbers

=14850*x[tex]10^{-3}[/tex]                  x[tex]10^{-3}[/tex] means to move the decimal of the number to the left 3 times. The number does not have a decimal so you start at end

=14.850

When you subtract a negative, the signs cancel and become addition, vice versa.

4-(-8) = 4+8

Answer: 12

Step-by-step explanation:

4-(-8)

= 4+8

=12

Answer:

To simplify the expression, we first need to perform the division before the addition.

6 x 10^-2 / (7 x 10^4) = 6/7 x 10^-2-4 = 0.000085714.... ≈ 8.57 x 10^-5

Now the expression becomes:

3 x 10^-3 + 8.57 x 10^-5

To add these two terms, we need to have them in the same power of 10. Therefore, we can rewrite 3 x 10^-3 as 0.003 x 10^-3.

0.003 x 10^-3 + 8.57 x 10^-5 = 0.0030857 x 10^-3

Now we can express the answer in scientific notation by moving the decimal point to the left until we have a number between 1 and 10, and taking note of how many places we moved the decimal point.

0.0030857 x 10^-3 = 3.0857 x 10^-6

Therefore, the simplified form of 3 x 10^-3 + 6 x 10^-2 / (7 x 10^4) (3 x 10^8) expressed in scientific notation is 3.0857 x 10^-6.

This means that the answer is a very small number, which makes sense given the small values of the original terms.

Answer:

154mm²

Step-by-step explanation:

The first step is to break down all the shapes.

- 4 triangles and one parallelogram

Lets find area of the upper triangles first

Formula: 1/2(b)(h)

A = 1/2 (7)(11)

A = 38.5mm²

Since there's two of those, multiply by 2

38.5mm² x 2 = 77mm²

Now, we move to the area of the bottom triangles

Same formula: 1/2(b)(h)

A = 1/2(7)(3)

A = 10.5mm²

Again, we multiply by 2 since there are two of those

10.5mm² x 2 = 21mm²

Lastly, we find the area of the parallelogram

Formula: b x h

For the base, we double the length of the base of the triangles

7 x 2 = 14

A = 14 x 4

A = 56mm²

Now we add all of them up

77mm² + 21mm² + 56mm²

= 154mm²

Answer:  $2, 3, $.50

Step-by-step explanation:

They want to know how much it is for each item.

So for the first one in order to make 2 grapes to 1 you would divide by 2 and if you divided the $4 by 2 you get $2

1.   $2

2.  3   you will divide both numbers by 3

3.  $.5  you will divide both numbers by 6

Answer:

1. $2

2. 3

3. .50 cents

Step-by-step explanation:

For each question you easily just divide! :)

For example:

1. $4 for 2 pounds of grapes- divide 4 by 2 and you get 2!

2. Latasha reads 9 pages in 3 minutes - divide 9 by 3 - you get 3!

3. A package of 6 pencils costs $3 - divide 3 by 6 - you get .50 cents!

i hope this helps!! :)

Answer:

[tex]\frac{8}{10}[/tex], or 80% probability

Step-by-step explanation:

To determine probability, we need to know how many "options" there are. There are 2 white spaces, and 8 red spaces, so we have a total of 10 spaces.

Of those 10 spaces, 8 of them are red. As a fraction, this is [tex]\frac{8}{10}[/tex], because 8 parts of the total ten are red.

To change this into a percent, we divide and then multiply by 100%.

[tex]\frac{8}{10}[/tex]= .8*100%= 80%

If you don't have a calculator, remember that percepts are just a way to show a portion of 100. If we need to multiply 10 by 10 to get the total 100, we must also multiply the top of the fraction, which gives 80.

Answer:

3.245

Step-by-step explanation:

You add all your values together and divide by the number of values there are.

The first step would be to plug in the given volume and solve for the radius, r:

64π = 4/3πr^3

Divide both sides by (4/3)π:

64π / (4/3)π = r^3

Simplify:

48 = r^3

Take the cube root of both sides:

∛48 = r

Simplify:

r ≈ 3.63

Therefore, the radius of the sphere with a volume of 64π is approximately 3.63 units.

Answer:

the value of r will be r =3.63

Answer:

105mins

Step-by-step explanation:

So if it takes them 2 miles in 30 mins. You have to find how much it takes them to hike for 1 mile. For that, you would have to do 30 divided by 2 which equals 15. So, if it takes him 15min to go for 1 mile you have to multiply 15 times 7. So it would take 105mins for him to hike for 7 miles.

Answer:
