Answer:

54.84 yd^2

Step-by-step explanation:

1/2BH

1/2(13)(8 7/16) = 54.84

Answer:

18.

Step-by-step explanation:

4yd is on the bottom.

9yd is on the left.

13yd is on the right.

The area for a triangle is [tex]\frac{1}{2} * b * h.[/tex] We add the numbers into the formula.

[tex]\frac{1}{2} *4*9 = 18.[/tex]

We do not use 13, because it is only going from one corner to the opposite corner. So, the answer is 18.

Hope this helped!

Answer:

the number of more people watched each screen on sunday is 103

Step-by-step explanation:

The computation of the number of more people watched each screen on sunday is shown below:

= Sunday - saturday

= (1576 ÷ 4) - (1164 ÷ 4)

= 394 - 291

= 103 more people

hence, the number of more people watched each screen on sunday is 103

Answer:

p(x)+Q(x)=(2x+3y)+(x+2)=2x+3y+x+2= 3x+3y+2

Answer:

3 bags

Step-by-step explanation:

Even though she will have extra she still will need 3 bags to get 12.

Answer:

3

Step-by-step explanation:

We know Ms.Smith is buying avocados and needs 12, we also are provided with the fact that she buys them in bags of 5.

If you take a look at the picture, we need to find a bag that fits 12 avocados in,  this would be 3. As in 3 bags that contain 15 avocados in total, though excessive amount, this is the bag that she would need to benefit her the most.

Answer:

the answer is that the graph represents something more than one

Step-by-step explanation:

Unfortunately, I do not have the question but the circle on the number represents that the answer cannot equal one but anything after one can be the answer.

So 1.0000000001 can be an answer but 1 cannot

the arrow pointed toward the right represents that the answer is continuous which means that any answer above one will be correct.

Answer:

Terry needs to buy 7 packages

Step-by-step explanation:

Terry has invited 31 people, meaning she needs 31 party favors

If they come in groups of five, we have to find how many packages(of 5) equal 31. Because 5 does not evenly multiply into 31, (it fits evenly inti 30) we have to add an extra package, meaning she will need 7 packages because 7×5 is 35, which is enough for each guest

Answer:

1) A

2) A

3) C

4) D

Step-by-step explanation:

Exponential decay is for 1) because as the years pass, the depth decreases.

2) if it decreases by 2%, this means 100%-2%= 98%=0.98.

3) same as 2).

4) The equation for this situation can be represented with y=30(0.98)^x. when x is between 5 and 6, the depth of the lake is approximately 26.7 meters. So, it takes around 5 to 6 years for the depth of the lake to decrease to 26.7 meters.

Answer:

9/32

Step-by-step explanation:

3 x 3 = 9. 8 x 4 = 32. 9/32

Step-by-step explanation:

First subtract 7 from both sides, so now you have 1/6x = -48 then divide both sides by 1/6

so x = -288

Sorry if its the wrong answer, thats what I got

Answer:

15x - 45 and -45 + 15x

Step-by-step explanation:

1. 15(x-3)

2. 15(3) = 45

3. 15x-45

4. -45 + 15x = 15x-45

5(3x - 9) and 3(5x - 15) are the other two expressions.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

15 (x - 3)

This can be written as:

1)

5 x 3 (x - 3)

5(3x - 9)

2)

3 (5x - 15)

Thus,

The other two expressions are:

5(3x - 9) and 3(5x - 15).

Answer:

poverty

Step-by-step explanation:

lack of workers makes no sense bcs the population was only increasing

limited recreational options don't make any sense either bcS that is not affected by population

and lack of transportation doesn't make any sense bcs it was the 1800's and people walked

Answer: B) Poverty

=====================================================

Explanation:

Unfortunately many people did not have much money to afford the basics such as a decent home and food to put on the table. Even if the person was working, they may be in a very dangerous job that provides little pay. An example could be a factory worker. So this is why choice B is the answer.

There were definitely plenty of able-bodied people, so there wasn't a shortage of workers. This allows us to rule out choice C. There also wasn't a lack of transportation since people either lived close and walked, or they had modes of transport such as rail or bike. Cars were starting to show up in the very late 1800s, but it wouldn't be until the early 1900s is when they became more commonplace. So we can rule out choice D.

Choice A can be ruled out since there were many recreation options such as going to the park or beach, or going to plays or classical music concerts, to name a few ways to have fun.

Answer:

Choice A.

Step-by-step explanation:

tan < ABC = 60/40

So m < ABC = 56.31 degrees.

This makes m < DBC = 56.31 / 2 =  28.15 degrees

tan 28.15 = DC / 40

DC = 40 tan 28.15

= 21.407 ft.

Answer:

1100 square inches

Step-by-step explanation:

Formula: LxW

Smallest rectangles area: 5*20=100= 1 rectangle

there are 2 smal  rectangles so= 100*2=200

Medium rectangles area: 5*30=150

There are 2 so= 150*2= 300

Biggest rectangle: 30*20= 600

Total Area: 200+300+600= 1100 square inches

Answer:

We gotta use Pythagorean theorem, fellas!

a^2 + b^2 = c^2

c^2 is the hypotenuse being squared.

a is a leg of a right triangle

b is another leg of a right triangle

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

we will use 61 for a

we will use 60 for b

a^2 + b^2 = c^2

61^2 + 60^2 = c^2

3721 + 3600 = c^2

7321 = c^2

[tex]\sqrt{7321}[/tex] = c (remember that c is hypotenuse)

c is rounded to 85.56 cm or 85.563 cm or 86 cm (depends on how the question wants the answer to look like)

ANSWER: 86 cm, 85.56 cm, or 85.563 cm

Answer:

The average amount of trail mix in each bag is [tex]\frac{1}{2}[/tex]lb

Step-by-step explanation:

First, we need to calculate the sum of all the trail mix

Sum of Trail Mix = [tex]\frac{1}{4}[/tex]lb +

Now count the numbers of trail mixes

Numbers of trail mixes = 12

Calculate the average amount of the trail mix using the following formula

Average Trail mix = Sum of Trail Mix / Numbers of trail mixes

Average Trail mix = 6 lb / 12

Average Trail mix = [tex]\frac{1}{2}[/tex]lb
