Answer 1

Answer:

Step-by-step explanation:

18. x + 25 = 55

x = 30

19. 2x - 5 = 95

2x = 100

x = 50

20. 3x - 22 = 2x + 26

x - 22 = 26

x = 48

21. 3x - 18 + 105 = 180

3x + 87 = 180

3x = 93

x = 31

22. 19x + 17x = 180

36x = 180

x = 5

27(5) = 135

23. 5x + 40 + 2x = 180

7x + 40 = 140

7x = 140

x = 20

5(20) = 100

2(20) = 40

5(20) + 40 = 100 + 40 = 140

Find the area of each figure. Round to the nearest tenth if necessary

Answers

Answer:

59.3

Step-by-step explanation:

First find the area of the the right triangles

5 * 4 / 2 = 10

Multiply it by 2 since there are 2 right triangles that are the same

10 * 2= 20

Then find the area of a semi circle

The radius is 5

π5^2 / 2= 39.27

39.27 rounded to the nearest tenth is 39.3

Add them together

20 + 39.3 = 59.3

59.3 is your answer

roshaun has saved 150$ and continues to add 10$ each week. Keegan starts with 0$ and saves 25$ each week. In how many weeks will they have the same amount of money?

Answers

Answer:

10 weeks

Step-by-step explanation:

Create a system of equations demonstrating Roshaun and Keegan's savings.

Roshaun: 150 + 10x Keegan: 0 + 25x

Let x equal the number of weeks they save their money.

In order to calculate how many weeks they will have the same amount of money saved, we need to set their equations equal to each other and solve for x.

150 + 10x = 25x

Subtract 10x from both sides of the equation.

150 = 15x

Divide both sides of the equation by 15.

x = 10

In 10 weeks, Roshaun and Keegan will have the same amount of money.

Answers

Answer:

x= 43, y=215

Step-by-step explanation:

Let one number be x,

Let the other number be y.

x= 5y

x - y= 172

Putting value of x in equation 2.

5y - y = 172

4y = 172

y= 172/4

y= 43

Putting value of y in eq. 1

x= 5(43)

x=215.

Find the value of x.

Answers

Answer:

x=6,24

Step-by-step explanation:

Use the Theorem of Pythagoras.

H^2= S^2+ S^2

8^2= 5^2 + S^2

64-25 = S^2

39 = S^2

6,24= S

S is x therefore x = 6,24

y varies jointly as x and z. y = 75 when x = 5 and z = 5. Find y when x = 4 and z=6. y =

Answers

Answer:

y = 72

Step-by-step explanation:

Joint proportion is given by the expression;

y = kxz

Given the following values;

y = 75, x = 5 and z = 5

To find the constant, k;

75 = k*5*5

75 = 25k

k = 75/25

k = 3

Next, we find the value of y when x = 4 and z= 6

y = kxz

y = 3*4*6

y = 72

Which tissue system in plants is most similar to the Integumentary system in animals? explain your reasoning (DON'T USE G.O.O.G.L.E) Which of the following statements about savings accounts is FALSE? Savings accounts may Have you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.Which words from the text describe what our brains use to fill in gaps in memory?
