need help asap:(

Answer:

the answer is x<4

and the line is an open circle line going to the left from positive 4 onward

Answer:

Step-by-step explanation:

Using the same proportion as the previous question

11/x = x / 8                   Cross multiply

x^2 = 88                     Factor 88 into at least 1 perfect square and something

x^2 = 4 * 22                Take the square root of both sides    

x = sqrt(4 * 22)

x = 2*sqrt(22)

= 23.5

hope it helps

Given:

A figure of a triangular prism.

Height of triangular base = [tex]9\dfrac{2}{3}[/tex] yd

Base of triangular base = 4 yd

Height of prism = 4 yd.

To find:

The volume of the triangular prism.

Solution:

Volume of a triangular prism is:

[tex]V=Bh[/tex]              ...(i)

Where, B is the area of triangular base and h is the height of the prism.

Area of triangular base is:

[tex]B=\dfrac{1}{2}\times base\times height[/tex]

[tex]B=\dfrac{1}{2}\times 4\times 9\dfrac{2}{3}[/tex]

[tex]B=2\times \dfrac{29}{3}[/tex]

[tex]B=\dfrac{58}{3}[/tex]

Putting [tex]B=\dfrac{58}{3}[/tex] and h=4 in (i), we get

[tex]V=\dfrac{58}{3}\times 4[/tex]

[tex]V=\dfrac{232}{3}[/tex]

[tex]V=77.33...[/tex]

[tex]V\approx 77.3[/tex]

The volume of the triangular prism is 77.3 cubic yards. Therefore, the correct option is 2.

Step-by-step explanation:

cuz it is corresponding angle

Answer:

Much like when you divide by a negative number, the sign of the inequality must flip! ... When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side!

It switches sides

Substitute the values of angles P and Q in an equation that equals 90 degrees

62° + 4x = 90°

Then isolate the variable by first subtracting 62 from both sides

62 + 4x = 90           →    4x = 28

-62           -62

Then divide both sides by 4

4x = 28               →  x = 7

/4    /4  

Answer:Ok I This question can be solved using a system of equation, which requires translating the above word problem into something that can be algebraically

Let O=oranges and  Let G=Grapefruit

5O +8G=235

3O + 2G=85

To solve, you must isolate one of the variables and then work from there. To do that multiply both sides of the bottom or second equation by four and then subtract the bottom equation from the top.

Which would look like this

5O +8G=235

12O + 8G= 340

Then subtract the bottom from the top to get this

-7O=-105

Solving for O we divide both sides by -7, and end up with O=15

Plugging that value back into one of our original equations to solve for G we get this

3(15) + 2G= 85

45 +2G=85

2G=40

G=20

So 1 case of each altogether would equal 15+20, or $35.

1a.) -5.36

Franco is requesting a group of negative numbers, so in this case, -5.36 is negative and would fall under that category.

1b.) 4.6272727

Mai is requesting the group to have repeating decimals, in this case, 4.62727 would work.

Answer:

20c= 30(c-9)

Step-by-step explanation:

The first step in solving a word problem is always to organize the information you have, and put it into equations to solve.

Let c be the cost per student originally.

The cost of the bus has not changed, so the cost/student * the number of students has not changed:

Answer:

the probability of pulling a marble that is not green is 7/10

Answer:

- 7 / 10

- 70%

Step-by-step explanation:

4 red + 3 green + 2 yellow + 1 blue = 10 marbles

If you remove green marbles:

4 red + 2 yellow + 1 blue = 7 marbles

So the probability of not pulling a green marble is 7 out of 10.

Answer: Choice D

They should be blocked by pain resistance so the subjects are as similar as possible.

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

Explanation:

The process of blocking in statistics is where we group up people in blocks, and each block is determined by a characteristic of some sort. In this case, we're grouping people up by pain resistance level. Those very resistant to pain will be in one group, while those who easily feel pain will be in another block, and so on. It might be effective to have a pain scale and sort people by that.

Blocking is done so that we eliminate unwanted variability. We are testing the effectiveness of the itching cream, so all we care about is if the itch reduces or not. We aren't worried about the levels of pain. However, it says that "Previous studies have shown the effects of treatment may vary based on a subject's pain resistance". So we group up the people by pain tolerance to help eliminate the variability of pain tolerance levels.

This is why choice D is the final answer.

Extra info:

Answer:D

Step-by-step explanation:

This is due to the question explicitly stating how the previous studies have shown the effects of treatment may vary based on a subjects pain resistance. This leads to the only option that relates to the study's background, D

Answer:

The first one.

Step-by-step explanation:

solving for x:

5/2 = 7.5/x

cross multiply

2 ×7.5 =5x

x= 2×7.5/5

x= 3

solving for y:

values of the small triangle over the bigger triangle-

5/6 =7/y

cross multiply and solve for y

y= 8.4

therefore (x= 3; y= 8.4)
