For his reading goal this nine weeks, Jeonhee wants to read 1,000 pages. The first week he read 10 pages per day. The second week he read 15 pages per day. The third week he read 20 pages per day. How many more pages does he need to read to reach his goal?

Answers

Answer:

955

Step-by-step explanation:

Ok, so his goal is to read 1,000 pages in 9 weeks. We know 1 week has seven days.

So let’s start with the first one. He reads 10 pages per day on the first week. That’s 10 x 7, which he read 70 pages for the first week.

As for the second week, it’s the same: 15 x 7 = 105 pages read.

Third week: 20 x 7 = 140 pages read.

Add: 70 + 105 + 140 = 175 + 140 = 315 pages read.

Subtract: 1,000 - 315 = 685.

That’s 685 pages he still needs to read until he hits his goal. Hope this helped! :D

A dinner cost $28.50 which included a 15% tip. How much was the tip?
Explain the answer please

Answers

I think it’s $1.60. Just the dinner was 26.60

Answer:

Tip: $4.275 = $4.28

Step-by-step explanation:

Use the formula: Tip = Tip% x Bill Total

In this case, the tip is 15% and the total bill is $28.50.

15% = 0.15

28.50 x 0.15 = 4.275

Round 4.275 to the hundredths, which equals 4.27

Braxton puts $1,275 into a savings account that earns 3% simple interest per year. How much total money will be in his account after 5 years?

A) $191.25
B) $1,466.25
C) $19,125.00
D) $20,400.00

Answers

Answer:

The answer would be B) 1,466.25

Step-by-step explanation:

The formula we'll use for this is the simple interest formula, or:

I= P x r x t

Where:

P is the principal amount, $1275.00.

r is the interest rate, 3% per year, or in decimal form, 3/100=0.03.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 1275 × 0.03 × 5 to get that:

The interest is: $191.25

Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),

or 1275.00 + 191.25 = 1466.25.

the answer is 1,466.25

Given the speeds of each runner below, determine who runs the fastest.

Stephanie runs 12 feet per second.
Liz runs 306 feet in 38 seconds.
Will runs 1 mile in 491 seconds.
Brooke runs 851 feet in 1 minute.

Answers

Answer:

Brooke

Step-by-step explanation:

We can solve this by figuring out how far each person runs a second

Stephanie runs 12 feet a second so nothing needs to be done here

Liz runs 306 feet in 38 seconds. To solve for the distance ran in 1 second we can divide (306/38)= around 8 feet

Will runes 1 mile in 491 seconds. A quick search will tell use that 1 mile is equal to 5280 feet and 5280/491 = 10.75

Brooke runs 851 feet in 1 minute or 60 seconds. 851/60 =14.18

Brooke obviously runs the furthest in one second and therefore she's the fastest runner

Eleanor and Max used two rectangular pieces of plywood, placed end-to-end, to make a long rectangular stage for the school play. One board was 6 feet long, and the other was 6 1/2

feet long. The two pieces of plywood had equal widths. The total area of the stage was 59 3/8
square feet. What was the width of the plywood?

Answers

The area is the product of length and width.

.. area = length * width

.. 61 5/8 = (7 +7 1/2) * width

.. (61 5/8)/(14 1/2) = width = 4 1/4 . . . . feet

The plywood was 4 feet 3 inches wide.

_____

A calculator that works with fractions figures this nicely. By hand, you might compute it as

.. 61 5/8 = (8*61 +5)/8 = 493/8

.. 14 1/2 = (2*14 +1)/2 = 29/2

.. (61 5/8)/(14 1/2) = (493/8)/(29/2) = (493/8)*(2/29) = 493/(4*29) = 493/116

.. 493/116 = 4 +29/116 = 4 +29/(4*29) = 4 1/4

Answers

Answer: 40 pi cm^2

Step-by-step explanation: the area of a circle is pi*r^2. the shaded region is the area of the large circle minus the area of the small circle. the larger circle has an area of 49pi and the smaller circle has an area of 9pi. 49pi-9pi is 40pi cm^2
