Answer:
add
(a+10)+2a+44=180
Subtract 44 first so now our equation is
a+10+2a=136
3a+10=136
3a=126
a=42
plug it into 2a since this is our exterior angle
2(42)
=84 degrees

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.

Answer:
Step-by-step explanation:
Note the following: 2^4 = 16; (x^3)^4 = x^12; and (y^4)^4 = y^16
Then your 4(2x^3y^4)^4 becomes 4*16*x^12*y^16

41pi cm2
8pi cm
80pi cm
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
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
