Michelle and Natasha each had to repair their new iPhones. The initial cost of each repair is $100. Michelle and Natasha each have two discount coupons. Each of them uses both coupons toward the cost of the repair. One coupon is for $25 off the repair cost and the other coupon is for 20% off the repair cost. Michelle and Natasha use their coupons in a different order, as shown below.

Michelle uses the 20% off the repair cost coupon first. She then uses the $25 off the repair cost coupon on the remaining balance.

Natasha uses the $25 off the repair cost coupon first. She then uses the 20% off the repair cost coupon on the remaining balance.

The regular price of a pair of Rothy's (water bottle shoes) is $145. They are on sale for 38% off. What is the sale price?

Answers

Answer:

$89.90

Step-by-step explanation:

38% corresponds to the decimal fraction 0.38.  

The amount of the discount is 0.38($145), or $55.10.  Subtracting this amount from the regular price yields $145 - $55.10 = $89.90.

A faster way of doing this problem is to subtract 0.38 from 1.00, obtaining 0.62, and then multiplying $145 by this 0.62:  $89.90.

Step-by-step explanation:

The company charges $45 a day for the car
as well as charging a one-time $25 fee for
the car’s navigation system (GPS). Write an
equation for the cost in dollars, C, as a
function of the number of days, d, the car
was rented.

Answers

Answer:

I personally find it easier to put my equation in words before actually writing the equation, so for this particular situation, the equation would sound like this :

→ The cost (C) is equal to 45$ a day (d) plus 25$!

Now that your equation is put into words, all that you have to do is write down the equation without the words :

→ C = (45d) + 25

If you want to make sure that your equation is correct, you can try it out, say for instance you want to rent a car for a week, so for a total of 7 days, and you want to see how much it would cost :

d = 7 (in this particular situation)

C = (45 × 7) +25

C = 315 + 25

C = 340

→ So it would cost 340$ to rent a car for a week!

Option 3

Step-by-step explanation:

By applying Pythagoras theorem in the given triangle,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

x² = (9.5)² + (10.5)²

x² = 200.5

x = √(200.5)

x = 14.16

x ≈ 14.2

Therefore, measure of the unknown side is 14.2 in.

Option (3) will be the correct option.

You know you are in trouble when a question says approximately. How approximate is approximately. My guess, and it is a guess, is that this means the nearest degree. That would be 14 degrees. The more exact answer is 13.80 and that zero matters. It is a place holder.

Answers

Answer:

7/6 or 1 1/6

Step-by-step explanation:

Here's how you add them!

5 /6  + 2/6  

Step 1

Since our denominators match, we can add the numerators.

5 + 2 = 7

Answer:

7 /6

Step 2

Now, do we need to simplify this fraction?

First, we attempt to divide it by 2...

Nope. Try the next prime number, 3...

Nope. Try the next prime number, 5...

Nope. Try the next prime number, 7...

No good. 7 is larger than 6. So we're done reducing.

Congratulations! Here's your final answer to 5/6 + 2/6

Answer:

[tex]\frac{5}{18}[/tex]

Step-by-step explanation:

To calculate the amount of acres planted in strawberries, all you need to do is  simple multiplication.

[tex]\frac{5}{6}[/tex] × [tex]\frac{1}{3}[/tex]

multiply the numerators by each other

[tex]5[/tex] × [tex]1[/tex] [tex]= 5[/tex]

the numerator of the new fraction is 5

multiply the denominators by each other

[tex]6[/tex] × [tex]3=18[/tex]

the new denominator is 18

the new fraction is [tex]\frac{5}{18}[/tex]
