Maggie Is Using A D Sized Battery For Her Science Project. The Radius Of The Battery Is 16.5mm And It

Answers

Answer 1

Answer:

48,153.3 mm³

Step-by-step explanation:

the battery is a cylinder

Volume of a cylinder = πr²h = π(16.5)²(56.3) = 48,153.3 mm³

Answer 2
Volume = πr2h
= π×16.52×56.3
= 15327.675π
= 48153.311176612 millimeters3

Meg laid 15 tiles in 50 minutes.
Jessica worked for 85 minutes at a faster rate per tile than Meg.
Choose all the rates that could be Jessica’s rate.

20 tiles in 85 minutes

24 tiles in 85 minutes

28 tiles in 85 minutes

1 tile in 3 minutes

1 tile in 4 minutes

Answers

Answer:

The correct options are C and D

Important information:

Meg laid 15 tiles in 50 minutes.

Jessica worked for 85 minutes at a faster rate per tile than Meg.

Step-by-step explanation:

The rate per tile of Meg is:

Rate = time/no. of tiles

Rate = 50/15

Rate = 3.333333...etc

Calculate the rates per tile for each option.

85/20 = 4.25

85/24 = 3.54167...

85/28 = 3.0357

3/1 = 3

4/1 = 4

From the above calculation is clear that the time spent per tile is less than Meg's rate in options C and D.

Therefore, the correct options are C and D.

Please solve!

Answer:

x = 55°

Step-by-step explanation:

The angles are complementary.  That means that they add to 90.

x + x - 20 = 90  Combine like terms

2x - 20 = 90  Add 20 to both sides

2x - 20 + 20 = 90 + 20

2x = 110  Divide both sides by 2

x = 55

Helping in the name of Jesus.

Answer:

x = 55 degrees; the angles are complementary

Step-by-step explanation:

First of all, the angles are complementary. I say this because complementary angles add up to 90 degrees and the square symbol identifies the angle as being a 90-degree angle.

Next, you add [tex]x-20+x[/tex] and set it equal to 90. With some quick addition and some properties of equality, you get the answer of 55 degrees.

Which expression is equivalet to (3x-1)-2.75(x+2)

A. 0.25x - 6.50

B. 0.25 + 1.00

C.0.25 + 4.50

D.0.25 -3.00


I would love an explanation to help me understand how to solve the other problems like this one

Answers

I think is B but I’m not sure

it is A. 0.25x - 6.50

You use distributed property first so the equation will be 3x - 1 - 2.75x - 5.50

Then you combine like terms so 3x - 2.75 will equal 0.25x

The subtraction symbol will stick with 1 making it -1 so the second part will be -1 - 5.50 will equal 6.50

And finally, the expression will be 0.25x - 6.50

Carrie the chef has 10 orders she needs to finish In 24 hours. The orders: A cake which will take a hour,a box of cookies which will take 45 minutes,a dozen donuts which will take 34 minutes,5 loaves of bread which will take 3.4 hours each,and 2 boxes of candy which will take 13 mins. How many minutes or hours will she have left over to relax?

Answers

Answer: Carrie the chef will have 268 minutes left over to relax.

Step-by-step explanation: Add up how many minutes each pastry will take, and convert hours into minutes. So, you will add 45+34 which is already at 79 minutes, then you do 3.4x5 (3.4 hours for 5 loaves of bread) which is 17 hours, converted into minutes is 1020 (17x60), then add the 13 minutes for the 2 boxes of candy. You'll get 1172, then you subtract it from 1440 (how many minutes there are in 24 hours) and you get 268! Therefore, she gets 268 minutes left!

Hope this helps!

How do I graph y = -1 = 2x and y = -4 + 2x?

Answers

Answer:

Slope = Rise/Run

To graph, you first need the y-intercept.

In y = -1 + 2x, the y-intercept is -1. Start in -1 and then go two units up, and 1 unit to the right which will represent the slops, 2.

In y = -4 + 2x, the y-intercept is -4, so you'll start at -4, then go 2 u its up, and 1 to the right which will represent the slope, 2.

To find y-intercept:

y = mx + b            |      main things:      m = slope       b = y-intercept

Hope it helps!
