Step-by-step explanation: 115 because the remain angle in that triangle is 65. 180-65 is 115. 45 because vertical angles are equal. 115 because 180-65 is 115. 110 because vertical angles are equal. 115 because vertical angles are equal.
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.

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:
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

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

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
