Little league baseball bats have barrels that measure 2.625 inches in diameter. What is the diameter of a bat in millimeters (mm), to the nearest millimeter?

2.54 cm = 1 inch
10 mm = 1 cm

Answers

I don’t know the answer but you would have to first convert the 2.625 inches into cm and then convert the cm to mm to get your answer
Convert 2.625 inches into centimeters and then convert it again but in millimeters you will get 66.7mm
No need to find diameter because it was given there in inches just convert

2.625 inches = 6.67 centimeters
6.67cm = 66.7mm

A phone company advertises a new plan in which the customer pays a fixed amount of $ 25 per month for unlimited calls in the country and $ 0.10 per minute for international calls . Write an equation for the monthly payment a customer pays according to the new plan . Use y for monthly payment , and x for international minutes.

Type the equation in the form y=ax+b without using any spaces. Write any decimals in the form 0.00

Answers

Answer:

y = a(.10) + 25

Step-by-step explanation:

Using the equation y = ax + b.

"$25 per month for unlimited calls in the country and $0.10 per minute for international calls."

The word "per" indicating that you are multiplying this.

The only variables being multiplied are a and x.

Thus, a is the amount of minutes, x is the cost of international calls and b is the cost of unlimited calls.

Leroi and Sylvia both put $100 in a savings account. Leroi decides he will put in an additional $10 each week. Sylvia decides to put in an additional 10% of the amount in the account each week.

Who has more money after the first additional deposit? Explain.

Who has more money after the second additional deposit? Explain.

Answers

Leroi’s account

$100
After first deposit = $100+$10=$110
After second deposit= $110 + $10 = $120


Sylvia’s account

$100
10% of $100 is $10
After first deposit = $100+ $10 = $110
10% of $110 = $11
After second deposit = $110 + $11 = $121

Therefore after their first deposit, both will have the same value in their accounts.
But after the second deposit, Sylvia will have 1$ more in her account than Leroi.

Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?

Answers

Answer:

$1343

Step-by-step explanation:

Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?

You need to turn 15% into a decimal.

Move the decimal point to the left 2 spaces.

15 ---> 1.5 ---> 0.15

Now multiply 0.15 by $1,580.

0.15 × $1,580

Which is $237.

Now subtract $1580 - $237.

Which is $1343.

Answer:

$1580*15/100=$237that is discount rate.

$1580-237=$1343 actually pay

(219,379.01 - x) / x = .3321

Answers

Answer:x = 164686.592598

Step-by-step explanation:

219379.01−x/x = 0.3321

−x+219379.01/x = 0.3321

Step 1: Multiply both sides by x.

−x+219379.01≈0.3321x

−x+219379.01 − 0.3321x = 0.3321x−0.3321x (Subtract 0.3321x from both sides)

−1.3321x + 219379.01 = 0

−1.3321x + 219379.01 − 219379.01 = 0 − 219379.01 (Subtract 219379.01 from both sides)

−1.3321x = −219379.01

−1.3321x/−1.3321 = −219379.01/−1.3321

(Divide both sides by -1.3321)

x = 164686.592598

Answer:

  164,686.59

Step-by-step explanation:

Carry out the division, then solve for x.

  (219,379.01 - x) / x = .3321 . . . . . given

  219,379.01/x -1 = 0.3321

  219,379.01/x = 1.3321 . . . . add 1

  219,379.01/1.3321 = x ≈ 164,686.59 . . . . multiply by x/1.3321

Rounded to 8 significant digits, the value of x is 164,686.59.

A fruit market equally divided 80 red apples into 8 containers, and equally divided 54 green apples into 6 containers. Natalie bought 1 container of red apples and 1 container of green apples.

Which equation could be used to find n, the total number of apples Natalie bought?


80 ÷ 6 + 54 ÷ 8 = n

80 ÷ 8 + 54 ÷ 6 = n

(80+54)÷(8+6)=n

80 × 8 + 54 × 6 = n

Answers

Answer:

The second one

Step-by-step explanation:

80 / 8 tells how many red

+ 54 / 6 tells how many green

The second one.

80 red apples into 8 containers = 80/8
54 green apples into 6 containers = 54/6

1 container of red = 80/8
1 container of green = 54/6

If I want to find the total of the apples Natalie bought I add the two containers together

So 80/8+54/6=n
n=10 red+9 green
n=19
19 apples

2(3y + 7 + 5) = 196 - 16
what’s the value of y?
And tell me how you know this and why or Y ahahahahahaha

Answers

Answer:

y=60

Step-by-step explanation:

196 - 16 = 180

7 + 5 = 12

12 + 3y = 15y

2 * 15y = 30y

180 ÷ 30 = 60

y = 60

Answer:

y=26

Step-by-step explanation:

Let's solve your equation step-by-step.

2(3y+7+5)=196-16

Step 1: Simplify both sides of the equation.

2(3y+7+5)=196-16

(2)(3y)+(2)(7)+(2)(5)=196+-16 (Distribute)

6y+14+10=196+-16

(6y)+(14+10)=(196=-16) (Combine Like Terms)

6y+24=180

Step 2: Subtract 24 from both sides.

6y+24-24=180-24

6y=156

Step 3: Divide both sides by 6.

6y/6 = 156/6

y=26
