Jefferson Elementary has a rectangular playground. A scale drawing of the playground is shown below.
10.5 cm
4.2 cm
The shortest side of the playground has an actual length of 33.6 meters.
What is the actual area, in square meters, of the playground?

Answers

I'm sorry if I get this wrong, but there isn't enough evidence.

If we think about the shorter side being 4.2 cm, then just divide 33.6 by 4.2 to give it a ratio. 33.6 / 4.2 is 8. The ratio of the scale drawing to the actual playground would be 1 : 8.

The longer side is 10.5, so just multiply that by 8. You'd get 84 meters. The only part left is getting the area.

Multiply 84 x 33.6 and you'd get 2822.4

The answer would be 2,822.4 squared.

Can someone please help me with this

Answers

Answer: x = 40

The equation you would write would be 2x + x + 60 = 180.

This is because you have to add all the angles inside the triangle in order to get 180°. Then, you solve the equation.

2x + x + 60 = 180
Add all the like terms.
3x + 60 = 180
Subtract 60 on both sides.
3x = 120
Divide 3 on both sides.
x = 40

Vinnie is searching online for airline tickets. Two weeks ago, the cost to fly from Denver to Hartford
was $200. Now the cost is $310. What is the percent increase? What would be the percent increase il
the airline charges an additional $50 baggage fee with the new ticket price?
The percent increase of the airline ticket is 11%.
annandad

Answers

Answer:

The ticket increased 57% of its original price

The baggage price was 44.5 increased 0.11% and then became 50

Step-by-step explanation:

So if the amount was 200 and now is 350, we should use division.

200 ÷ 350 = 0.5714285714285714 which you can round to 0.57 or as many digits as the question asked for. In thise case I will use 0.57

0.57 converted to percentage is 57%

About the second question

now you know the amount after increase and the percentage. So all you have to do is reverse.

11% = 0.11

0.11  ✕ 50 = 5.5    

this means the price increased 5.5

50 - 5.5 = 44.5

Challenge The numbers of home runs a baseball player hits during spring training and during the regular season for four years are shown. Decide if the relationship between home runs hit in spring training and during the regular season is proportional. If the table represents a proportional relationship, find how many home runs are hit during the regular season if the player hit 3 during spring training​

Answers

Answer:

12

Step-by-step explanation:

Key word: Most likely

First try to find the constant of proportionality

8/2= 4

4/4= 1

20/5=4

24/6=4

Since it says most likely we would say the constant of proportionality is 4.

Since they are asking for 3 homes runs we will do 3 times 4

[tex]3[/tex]×[tex]4=12[/tex]

The player will hit 12 home runs are hit during the regular season if the player hit 3 during spring training.

What is constant of proportionality?

The constant of proportionality is the ratio between two directly proportional quantities.

Two quantities are directly proportional when they increase and decrease at the same rate.

The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

Finding the constant of proportionality :-

8/2= 4

4/16= 4

20/5=4

24/6=4

Since, the constant of proportionality is 4.

And, they are asking for 3 homes runs we will do 3 times 4

Therefore, 3 x 4 = 12

Hence, the player will hit 12 home runs are hit during the regular season if the player hit 3 during spring training.
