Answer:

30 blocks

Step-by-step explanation:

60 minutes = 1 hour

For one hour, she will walk 7.5 blocks.

The rate is 7.5blocks per hour.

Multiply this by 4 hours, and you will get 30 blocks.

(7.5)4 = 30

Answer:

Greta will be earning 3.6/h more at her new job.

Step-by-step explanation:

To find the difference subract Greta‘s salary from her current job from Greta’s salary from her future job.

To find Greta’s salary (numerator) at her future job divide her current weekly salary ($729) by 45h then multiply that answer (16.2) by the increase in salary 10% or 1.1. You should end up with $17.82- this is your numerator. To find the denominator divide her current hours (45h) by 45 then multiply that answer (1) by 0.9 which is the 10% decrease in hours. Now you have a fraction ($17.82/0.9) then multiply that fraction by 1.1/1.1 to get the denominator to 1 hour so you can subtract the fractions. You should end up with $19.8/h.

Now subtract Greta’s current salary ($16.2/h)- you just take the numbers from the first part before you increase or decrease- from her future salary ($19.8/h), you will end up with 3.6/h.

I was challenged to write this in a single equation:

[((($729\45h)x1.1)/((45h\45)x0.9))x1.1/1.1]-[($729\45h)/(45h\45)]

=$3.6/h

/ means a fraction bar

\ means division

Also I am just a student so please tell me if you find any mistakes I could fix or any suggestions to make this a better explanation, and if you have any questions ask away.

Answer:

per year: $47,760 per year

per week: $918.46 per week

Step-by-step explanation:

$3980 per month x 12 months = $47,760 per year

$47,760 per year divided by 52 weeks = $918.4615384615

Since we're talking money, let's round off our answer to the hundredths place ($918.46 per week)

Double check our answer (918.46 x 52 = 47,760) great!

Answer:

47760 per year

918.46154 per week

Step-by-step explanation:

$3,980 x 12= $47760

$47760/52= $918.46154

Answer:

4/5

Step-by-step explanation:

1/2=5/10

5/10+3/10=8/10

simplified or  8/10 divided by 2 =4/5 and u cant simplify it anymore

Answer:

4/5

Step-by-step explanation:

convert 1/2 to 5/10 then and 3/10 then simplify and you get 4/5

Answer:

y=6

Step-by-step explanation:

y= -3/2(-4) : y=4

y=-2 3/4(-4)

y=3/2. 4

y= 3×4/2

y =12/2

12/2 =6

y =6

Answer:

[tex]p-value = 0.9953[/tex]

Step-by-step explanation:

Given

[tex]P = 40\%[/tex] --- proportion of population

[tex]n = 200[/tex] -- samples

[tex]p = 31\%[/tex] -- proportion of samples

Required

Determine the p value

First, calculate the standard deviation ([tex]\sigma[/tex])

[tex]\sigma = \sqrt{\frac{P*(1 - P)}{n}}[/tex]

[tex]\sigma = \sqrt{\frac{40\%*(1 - 40\%)}{200}}[/tex]

[tex]\sigma = \sqrt{\frac{0.40*(1 - 0.40)}{200}}[/tex]

[tex]\sigma = \sqrt{\frac{0.40*0.60}{200}}[/tex]

[tex]\sigma = \sqrt{\frac{0.24}{200}}[/tex]

[tex]\sigma = \sqrt{0.0012}[/tex]

[tex]\sigma = 0.0346[/tex]

Next, we calculate the z score

[tex]z = \frac{p - P}{\sigma}[/tex]

[tex]z = \frac{40\% - 31\%}{0.0346}[/tex]

[tex]z = \frac{9\%}{0.0346}[/tex]

[tex]z = \frac{0.09}{0.0346}[/tex]

[tex]z = 2.6012[/tex]

[tex]z \approx 2.60[/tex]

From the z table, the p value of [tex]z = 2.60[/tex] is: 0.9953

Hence:

[tex]p-value = 0.9953[/tex]

Answer:22%

Step-by-step explanation:

The simplest form of the total of 75/6 would be 432 / 7500.

A percentage is a minimum number or ratio that is measured by a fraction of 100. Suppose the value of which a thing is expressed in percentage is "a' Suppose the percent that considered thing is of "a" is b%

Then the percent; per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Given that out of 75/6 is 72%.

Therefore, it will be written as;

x of 75/6 = 72%.

We need to find the value of total x.

x of 75/6 = 72%.

x × 75/6 = 72%

x × 75/6 = 72/100

Cross multiplication;

x = 72/100  ×  6/75

x = 432 / 7500

x = 0.0576

Hence, the simplest form of the total of 75/6 would be 432 / 7500.

Answer:

y = (7w - 3m) / 3a

Step-by-step explanation:

w = 3/7ay + 3/7m

multiply each side by 7 to eliminate fractions

7w = 3ay + 3m

3ay = 7w - 3m

y = (7w - 3m) / 3a
