Answer 1

Answer & Step-by-step explanation:

37.

Linda walked 3/4 (or 75%) of a track which is 3.5 miles long

Multiply 0.75 by 3.5 to get 2.625 miles (or 2 and 5/8 miles)

38.

We need to multiply the 2 and 3/8 mile track by 2 and a half (2 and 0.5)

1/8 is 0.125

2/8 is 0.25

3/8 is 0.375

The track is 2.375 miles long.

Multiply 2.375 by 2.5

The track will be 5.9375 miles long after 5 years ( or 5 and 15/16 miles)

Answer 2

Step-by-step explanation:

37) ¾×7/2

21/8 miles = 2⅝miles .

38) (19/8×5/2)+19/8

= 95/16+19/8

= 133/16 = 8 5/16 miles .

hope this helps you.

The coldest day in ohio clocked in at 40 below zero. In one day though the temperature changed to 20 below zero How much temperature change was there that day

Answers

40 below 0 would be -40 and 20 below 0 would be -20°. So there’s a change of (increase of) 20° that day. It would also make sense if you drew a number line. You would see the interval between -40 and -20 is 20.

Hamish buvs a new car for $20000
The car depreciates in value by 19% each year.
Work out the value of the car at the end of 3 years.
Give your answer to the nearest $

Answers

Answer:

The correct answer is $10,629

Step-by-step explanation:

Here is how I got it!

First, you will have to borrow the 20,000 from the word problem.

Next, multiply 20,000 with 0.81 with the power of 3

[tex]20,000*0.81^3=n[/tex]

The 3 is the number of years, n is the nearest $ answer.

First, do [tex]0.81^3[/tex]

[tex]0.81*0.81*0.81=0.531441[/tex]

(Wow, that's a crazy number!)

With 0.531441, multiply it with 20,000

[tex]20,000*0.531441=10628.82[/tex]

10,628.82 is technically (in money) $10,628.82 (with .82 being eighty-two cents).

Finally, it states to answer to the nearest $.

Just round up the .82 to 1 dollar which will just add one more dollar to 10,628

[tex]10,628[/tex] ⇒ [tex]10,629[/tex]

Add you $ symbol

With the result being: $10,629

Answer:

$10629

Step-by-step explanation:

First you have to work otu the percentage decrease:

100 - 19 = 81

81/100 = 0.81 (/ means divide)

Then you have to work the amount after 3 years:

Long Method

20000 x 0.81 = 16200

16200 x 0.81 = 13122

13122 x 0.81 = 10628.82

or Short Method

20000 x 0.81³ = 10628.82

Finally you round it to the nearest $:

10628.82 ⇒ 10629
