Justine earned $28,000 during the first year of her job at city hall. After each year she received a 6% raise. Find her total earnings during the first five years on the job.
Answer:
$ 157838.60 in 5 years
Step-by-step explanation:
r = 1.06
sum of geometric seq = a1 ( 1-r^n)/(1-r) n = 5
28000 ( 1 - 1.06^5) / ( 1-1.06) = 157838.60
Find the measure of a, b, c, d, e
Answer:
a:90 b:90 c:42 d:48 e:132
Step-by-step explanation:
assuming the picture is accurate^^^
a = 90°
b = 90°
c = 42°
d = 48°
e = 132°
Step-by-step explanation:
Here as you can see c and 132° is vertically opposite to each other so it can be name as vertically opposite angle....
Vertically opposite angle are always equal to each other....e = 132°
Now....
here c and d are supplementary angle...
c + d = 180°
132° + d = 180°
d = 180° - 132°
d = 48°
Now...
b = 90° ( being vertically opposite angle )
Here a and b are supplementary angle ....
a + b = 180°
a = 180° - 90°
a = 90°
Now...
c + 138° = 180° ( supplementary angle )
c = 180° - 138°
c = 42°..

the length of a rectangle plus its width is 35 cm the area 306 what are the length and width of the rectangle
Step-by-step explanation:
Let width be w, length be l
l + w = 35, so w = 35 - l
lw = 306
l(35-l) = 306
35l - l^2 = 306
l^2 - 35l + 306 = 0
(l - 17)(l - 18) = 0
l = 17 or 18
When length = 17, width = 35-17 = 18
When length = 18, width = 35-18 = 17
A loaf of bread can be modeled by a rectangular prism topped with half a right cylinder. David measures the dimensions of the prism as 5 in by 5 in by 13 in. Using those dimensions, find the volume of the loaf. Round your answer to the nearest tenth if necessary. (Note: diagram is not drawn to scale.)

What is Rectangular prism? A rectangular prism is a three-dimensional object that uses rectangles as parallel bases. The volume of rectangular prism is Length x width x heightHow to Solve the Problem?The dimension of the prism given are 5in , 5 in , 13in
We need to find the volume of the loaf of the bread
So ,
The volume of rectangular prism is Length x width x height
V1 = 5*5*13
∴ V1 = 325[tex]in^3[/tex]
The volume of half a right cylinder
V2= ([tex]\frac{1}{2}\pi r^{2}h[/tex])
∴ V2 = ([tex]\frac{1}{2}*(5)^{2}* 13[/tex])
∴ V2= 162.5 [tex]in^3[/tex]
∴ Volume of loaf of bread is V = V1+V2

A book has 180 pages. Haley read 12 pages each day.after a certain number of days there are 60 pages left,which equation and solve for X gives the number of days he read
Answer: She read for 10 Days, equation below
Step-by-step explanation:
Number of pages = 180
Rate = 12pages Per day
Number of days read = (180-60) /12
Days read = (total no of page - page left)/page read per day
= 120/ 12 = 10 days
Days remaining = pages left /page per day
=60/ 12 = 5

Step-by-step explanation:
(1,1/2)(2, 1/4), (3, 1/9), (4, 1/16) are the ordered pairs which could be generated by an exponential function.
What is a function?A relation is a function if it has only One y-value for each x-value.
An exponential function is a Mathematical function in the form f (x) = aˣ, where “x” is a variable and
a is a constant which is called the base of the function and it should be greater than 0.
We have to find the set of ordered pairs could be generated by an exponential function.
(1,1/2)(2, 1/4), (3, 1/9), (4, 1/16) represents the exponential function.
y=1/2ˣ
y=2⁻ˣ
Hence, (1,1/2)(2, 1/4), (3, 1/9), (4, 1/16) are the ordered pairs which could be generated by an exponential function.

Howie wants to get a car loan with 4% simple interest rate. If the car
costs $25,000, how much would Howie need to pay back at the end of
one year, including the interest?
Answer: $26,000
Explanation:
i = simple interest
P = 25,000 = amount loaned
r = interest rate in decimal form = 0.04
t = number of years = 1
So,
i = P*r*t
i = 25000*0.04*1
i = 1000
Howie needs to pay $1,000 in interest on top of the $25,000 loaned to him. In total, he needs to pay back 1,000+25,000 = 26,000 dollars.

48 : 1 or 48 to 1
Step-by-step explanation:
to find out the answer we have to first find out what 8 feet is in inches as shown below
8 * 12 = 96
then we apply the inch value to a scale factor setup where 96 is the larger set and 2 is the smaller image
96 : 2
find the least common denominator...
96 / 2 : 2 / 2

When Adam sights the top of a 10-ft-high statue from 100 ft away, he finds an angle of elevation of 2.3°. When his friend Mark stands in the same location and sights the top of the same statue, he finds an angle of elevation of 2.6°. Assuming both boys measured correctly, which boy is taller? By how much?
Answer:
Adam's height - Mark's height =
[10 - 100tan (2.3)] - [10 - 100tan(2.6) ] =
≈ [5.96ft - 5.46 ft] =

a town is 61km north of 23km east of town B.bCalculate the bearing of A from B
Answer:
20.7°
Step-by-step explanation:
Bearing angle is measured clockwise from north. The geometry can be modeled by a right triangle with the sides equal to the distances north and east of town B. The tangent relation can be used to find the angle.
__
The attachment shows the geometry. The relevant angle relation is ...
Tan = Opposite/Adjacent
tanIβ) = 23/61 . . . . . where β is the bearing angle
The angle value can be found using the arctangent function.
β = arctan(23/61) ≈ 20.659°
The bearing of A from B is about 20.7°.
