90 minutes in fraction hour?​

Answers

Answer 1

Answer:

1.5 Hours

Step-by-step explanation:

So, 90 minutes is between 1 hour and 2 hours (2 x 60 = 120 minutes). It is exactly half way between, hence 90 minutes is 1 and 1 half hours (or less formally, 1 and a half hours).

or  

90 Minutes = 1.5 Hours = 1 Hour and 30 Minutes. Minutes to hours Time Converter 90 hours to minutes. This conversion of 90 minutes to hours has been calculated by multiplying 90 minutes by 0.0166 and the result is 1.5 hours.

Answer:

x = 15

Step-by-step explanation:

x + 2y = 37

x - y = 4

x + 2y = 37

2x - 2y = 8

3x = 45

x = 15

Answer: (4) x = 15

Steps:
1. Isolate y in the equation x - y = 4
x - y = 4
-y = 4 - x
y = 4 - x / -1
2. Substitute value of x (15) into the new equation y = 4 - x / -1
y = 4 - 15 / -1
y = -11 / -1
y = 11
3. Plug in your y value (11) and x value (15) into the equation x + 2y = 37
15 + 2(11) = 37
15 + 22 = 37
37 = 37 ✅
4. Plug in your y value (11) and x value (15) into the equation x - y = 4
15 - 11 = 4
4 = 4 ✅

both equations are true with the value of x being 15 therefore your answer is
(4) x = 15

have a great day!!!

If two ratios are similar we called the ratios to be in proportion.

The length of side x is 6 cm.

What is proportion?

If two ratios are similar we called the ratios to be in proportion

We have,

Two shapes:

Consider the bigger shape width = 15 cm and length = 10 cm.

Consider the smaller shape width = 9 cm and length = x cm.

Let the ratio of bigger shape:

= Width / length

= 15/10

Let the ratio of smaller shape:

= Width / length

= 9/x

If the two figures are mathematically similar we can say that the two figures are in proportion.

We can write it as:

15/10 = 9/x

3/2 = 9/x

x = 6

Thus the length of side x is 6 cm.

Sra bought a pair of shoes that were on sale for 30 percent off. If the oringal prices was 29 what is the sale price on the shoes?

Answers

Answer:

$20.30

Step-by-step explanation:

Original price = 100% of the price

100% = $29

1% = 29 ÷ 100 = 0.29

Sale percentage = 30%

30% = 0.29 x 30 = 8.70

Since they are asking for the sale price of the shoes, it means the price of the shoes after the discount of the sale percentage.

29 - 8.70 = 20.3
