−2 1/4=r−4/5

Help

Plz

Answers

Answer 1

Answer:

r=-29/20

Step-by-step explanation:

because

-2 1/4 will be -9/4=r-2/5 now you add 2/5 to both sides

witch means you have to increase the denominator to the greatest common denominator of 4 and 5 witch is 20 multiply the number used to combine with the denominator to get 20 to the numerator so itll be -45/20+16/20 witch will be -29/20 so there fore r=-29/20 or 1 9/20.

A shoe store is having an After Holiday sale and everything must go! If all the shoes are marked 60% off, how much do you pay for 2 pairs of shoes that cost $45 and $75?

Answers

Answer:

$48

Step-by-step explanation:

Find 1% of each pair of shoe first.

1 pair of shoe which cost $45:

100% = 45

1% = 45 ÷ 100 = 0.45

Other pair of shoe which cost $75:

100% = 75

1% = 75 ÷ 100 = 0.75

Now find 60% of each pair, the sale percentage.

1 pair of shoe which cost $45:

60% = 0.45 x 60 = $27

Other pair of shoe which cost $75:

60% = 0.75 x 60 = $45

Now, do full price - 60% of it.

$45 - $27 = $18

$75 - $45 = $30

Now add them up.

$18 + $30 = $48

Simon earns $8.50 per hour for up to 30 hours of work
in a given week. For each hour Simon works over 30
hours in a week, he earns 1.5 times his regular hourly
rate. How much does Simon earn for a week in which
he works 35 hours?

Answers

Answer:

$318.75 for a 35 hour work week.

Step-by-step explanation:

8.50 x 1.5 = 12.75 for every hour extra

8.50 x 30 = 255

12.75 x 5 = 63.75

255 + 63.75 = 318.75

The required earnings for Simon for the 35 hours is $318.75.

Simon earns $8.50 per hour for up to 30 hours of work in a given week. For each hour Simon works over 30 hours in a week, he earns 1.5 times his regular hourly rate. How much does Simon earn for a week in which he works 35 hours is to be determined.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

here,
The hourly rate for 30 hours is $8.50 per hour.
Total earning for 30 hours = 8.50 × 30 = $255
For hourly earnings increase by 1.5 times post 30 hours,
So the required hourly income after 30 hours = 8.5×1.5 = 12.75
According to the question,
Simons earning for 35 hours = 8.5 × 30 + 12.75 × 5  = $318.75

Thus, the required earnings for Simon for the 35 hours is $318.75.

Given the lengths of sides XY and XZ as shown in triangle XYZ below, what is the length of side YZ?

a. 5√13

b. 12

c. √194

d. 18

e. 5√5

Answers

Answer:

YZ = 12

Step-by-step explanation:

From the question given above, the following data were obtained:

Length of XZ = 13

Lenght of XY = 5

Lenght of YZ =?

The length of YZ can be obtained by using pythagoras theory since the figure is a right angle triangle. This can be obtained as follow:

XZ² = XY² + YZ²

13² = 5² + YZ²

169 = 25 + YZ²

Collect like terms

169 – 25 = YZ²

144 = YZ²

Take the square root of both side.

YZ = √144

YZ = 12

Therefore, the length of YZ is 12

Answers

Answer:

d = √389

Step-by-step explanation:

to find c we use 15 and 8 into the formula of "a^2 + b^2 = c^2" which is 17. Now we use 17 and 10 as a and b to find c in the formula which is d.

a^2 + b^2 = c^2

10^2 + 17^2 = x^2

100 + 289 = x^2

389 = x^2

√389 = √x^2

√389 = x
