Will works 7 hours a day, 6 days a week.

exis [7]

A day
= £9.20x7
= £64.40

6 days
£64.40x6= £386.40

The wages he has after he shared it with his mom
£386.40/7x5
= 55.20x5
= £276

£1932/£276= 7

It will take him 7 weeks to afford a car worth £1932.

Addie walked 2 1 2 miles in 45 minutes. Suzie covered 2 2 5 miles in 2 3 of an hour. Which girl walked faster? By how much?

kobusy [5.1K]

Answer:

Suzie walks faster by 0.27 miles per hour.

Step-by-step explanation:

Addie walked $2\frac{1}{2}$ miles in 45 minutes and Suzie covered $2\frac{2}{5}$ miles in $\frac{2}{3}$ of an hour.

So, Addie walked 2.5 miles in 45 minutes i.e. $\frac{45}{60} = 0.75$ hours.

Therefore, the walking speed of Addie is $\frac{2.5}{0.75} = 3.33$ miles per hour.

Again, Suzie covered $2\frac{2}{5}$ i.e. 2.4 miles in $\frac{2}{3}$ i.e. 0.67 hours.

So, the walking speed of Suzie is $\frac{2.4}{0.67} = 3.6$ miles per hour.

Hence, Suzie walks faster by (3.6 - 3.33) = 0.27 miles per hour. (Answer)

the population at Saint Maria High increased from 1800 students ten years ago to 1926 students last year. What was the percent i

Ket [755]

It’s a 7% increase. When you want to find percent increase/decrease, you want to subtract the numbers of the before and after. In this case, subtract 1926 and 1800, which will equal 126. Then, percent over 100 would be the first fraction, but since you don’t know the percent, put x. The second fraction is the amount of change over the original number. In this case, the amount of change will be 126 and the original is 1800. x/100=126/1800 now you just cross multiply and solve. You will end up with 7

Bernardo and Ogechi were asked to find an explicit formula for the sequence 1\,,\,8\,,\,64\,,\,512,...1,8,64,512,...1, comma, 8,

MatroZZZ [7]

Answer:

$h_{n}=1.(8)^{n-1}$ will be the correct formula for the given sequence.

Step-by-step explanation:

The given sequence is 1, 8, 64, 512...........

The given sequence is a geometric sequence having a common ratio (r) of

r = $\frac{\text{Second term}}{\text{First term}}$

r = $\frac{8}{1}=8$

Since explicit formula of a geometric sequence is given by

$T_{n}=a(r)^{n-1}$

where $T_{n}$ = nth term of the sequence

a = first term of the sequence

r = common ratio of the successive term to the previous term

Now we plug values of a and r in the formula to get the explicit formula for the given sequence.

$T_{n}=1.(8)^{n-1}$

Therefore, if Bernardo is saying that the formula of the sequence is

h(n) = $1.(8)^{n-1}$ then he is correct.

Cindy’s parking garage charges $3.50 for weekday parking, and weekends are half price. If Cindy parked in the garage 20 times pe

Pachacha [2.7K]

Answer: $\$64.75$

Step-by-step explanation:

You know that for weekdays parking the price is $3.50 and weekends are half price. Then for weekends, the price is the following:

$\frac{\$3.50}{2}=\$1.75$

You know that Cindy parked in the garage 20 times per month, and three of these days were weekend days. This means that she parked 17 times in week days and 3 times in weekends days.

Therefore, the total amount of money she would spend on parking per month can be calculated with:

$Total\ per\ month=17(\$3.50)+3(\$1.75)\\\\Total\ per\ month=\$59.5+\$5.25\\\\Total\ per\ month=\$64.75$
