Answer:

∠ ABC = 87°

Step-by-step explanation:

∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so

2x - 17 + x + 32 = 180 , that is

3x + 15 = 180 ( subtract 15 from both sides )

3x = 165 ( divide both sides by 3 )

x = 55

Then

∠ DBE = x + 32 = 55 + 32 = 87° , thus

∠ ABC = ∠ DBE ( vertical angles )

∠ ABC = 87°

Answer:

$367.38 is the cost to stain the entire deck.

Step-by-step explanation:

Here is what you need to know beforehand:

Diameter is a line that goes through a circle. Radius is a line that goes from the edge of the circle all the way to the center/a line that goes halfway through the circle.

--------------------------------------------------------------------------------------------------------------

First, find the area of the circle. Here is the formula:

Area = 3.14 (Pi) x r²

Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m

So the formula will look like this:

Area = 3.14 x 6²

Then, you just do the math:

Area = 3.14 x 6²

Area = 3.14 x 36

Area = 113.04

The goal of the problem is to find the amount of money Emma needs. Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:

Answer = 113.04 x 3.25

Answer = 367.38

$367.38 is the cost to stain the entire deck.

Answers

Answer:

2/33

Step-by-step explanation:

1.Since a number cube has six sides, and the word mathematics has 11 letters, and there are four vowels in mathematics, the probability of rolling a 3 in a number cube is 1/6. The probability of choosing a letter that is a vowel in mathematics is 4/11.

2. You multiply them together. 1/6*4/11=2/33.

3. The answer is 2/33.

Any sequence of transformations that include a “dilation” changes the overall size of the shape, so your answer would actually be “B” since it’s only being rotated and reflected. In other words, the location of the shape is the only thing being changed.

Amanda has 227 worth of bills in her purse. she has 6 more $5 dollar bills than $10 bills. The number of $1 bills is three fewer than 25 times the number of $10 dollar bills. How many of each does amanda have?

Answers

I think it’s 20 I hope that works

Answer:

Step-by-step explanation:

x = $5 dollar bills

y = $10 dollar bills

x + y = 15

5x + 10y = 120

5x + 10(15-x) = 120

5x + 150 - 10x = 120

-5x = -30

x = 6, so y = 9

There are six $5 bills and nine $10 bills.

Luke and Pedro work for Crown Carpentry. On Thursday, they each hung the same amount of wooden trim, but Pedro finished first. On Friday, they will work for the same amount of time hanging trim in a new movie theater. Will Pedro likely hang more trim or less trim than Luke?

please help

Answers

I think he’ll hang more because on Thursday, they both hung the same amount but Pedro finished first meaning he can hang trim faster than Luke. So if they both worked for the same amounth of time, for example if Luke worked for as much time as it took Pedro to hang trim on Thurday, Luke wouldn’t have been finished. I hope that makes sense!

If Stefan has 1 bouncy ball, Hannah would have 20.

Formula.

Stephan's Amount + 19 = Hannah's Amount

Solving Your Problem.

We will do the same thing except replacing "1" with "b".

b = Stefan's Amount

b + 19 = Hannah's Amount

We are just adding 19 to his.
