If employment is expected to increase by 14.8% between 01/2009 and 01/2016 and the employees number 19, 100 in 01/2009, how many total employees will there be in 01/2016?
Based on the rate of increase, the number of employees that will be there in 2016 is 21,927 people.
Number of employees in 2016This can be calculated by the formula:
= Employees in 2009 x ( 1 + rate of increase)
Solving gives
= 19,100 x (1 + 14.8%)
= 21,926.8
= 21,927 people
In conclusion, there will be 21,927 people in 2016.

The smaller triangle is a dilation of the larger triangle with a center of dilation at (2, -1),
What is the scale factor of the dilation?
A) 1/3
B) 1/2
C) 2
D) 3
Answer:
The answer is C.
Answer: B) 1/2
How to get that answer:
The larger triangle (preimage) has its vertical side of 6 units.
For the smaller triangle (image), the vertical side is 3 units.
The scale factor is image/preimage = 3/6 = 1/2
Meaning that the smaller triangle's side lengths are 1/2 of the larger triangle's side lengths.
You can use this trick to compare the horizontal sides as well.

Brainlyest for the first and quickest!
Answer:
10% of 45 is 4.5
30% of 45 is 13.5
Step-by-step explanation:
10% of 45 is 4.5 because you can multiply 4.5 10 times to get 45. Because 30% is 3 times the amount as 10%, you can multiply 4.5 x 3 to get 13.5
The accurate answer to the list of percentages given is you can multiply 4.5 x 3 to get 13.5.
What is a PercentageThis refers to the unit that is used to represent a whole and is denoted with the % sign and is a total over 100.
Hence, because
10% of 45 is 4.530% of 45 is 13.5If we expand, we would see that 10% of 45 is 4.5, 30% of 45 is 13.5 and because 30% is x3 the amount of 10%, you can multiply 4.5 x 3 to get 13.5

Jose's monthly bank statement showed the following deposits and withdrawals:
-$32.50, $46.25,-$16.04,-$7.50, $98.16
If Jose's balance in the account was $58.64 at the beginning of the month, what was the account
balance at the end of the month?
(HELP PLEASEEE)
Answer:
$147.01
Step-by-step explanation:
$58.64 - $32.50 is $26.14
$26.14 + 46.25 is $72.39
$72.39 - ($16.04+$7.50) is $48.85

The basement for a house is being excavated and the rectangular hole measures 11m by 14,5m by 4m. The soil is being hauled away in a dump truck which has an open-box bed of 4m by 3m by 200 cm . The truck Cant be overloaded at any time. How many trips will the dump truck have to make a haul away all of the soil.
Using volume of a rectangular prism, it is found that the dump truck will have to make 266 trips to haul away all of the soil.
What is the volume of a rectangular prism?The volume of a rectangular prism of length l, width w and height h is given by:
[tex]V = lwh[/tex]
In this problem, both the hole and the open-box bed are rectangular, hence the number of trips is the ratio between the volumes of the hole and of the open-box bed.
What is the volume of the volume of the hole?The dimensions in meters are [tex]l = 11, w = 14.5, h = 4[/tex], hence:
[tex]V_h = 11(14.5)(4) = 638[/tex]
What is the volume of the volume of the open-box?The dimensions in meters are [tex]l = 4, w = 3, h = 0.2[/tex], hence:
[tex]V_b = 4(3)(0.2) = 2.4[/tex]
What is the ratio of the volumes?It's their division, hence:
[tex]r = \frac{V_h}{V_b} = \frac{638}{2.4} = 265.8[/tex]

Carly’s bake shop requires 3.5 hours of labor to produce one cake and 2 hours of labor to produce one pie, and the shop has a maximum of 70 total labor hours available. If X1 represents number of cakes and X2 represents number of pies, how would this constraint be written?
Step-by-step explanation:
3.5 hours for 1 cake means 3.5 hours per cake.
similar : 2 hours for 1 pie means 2 hours per pie.
so, if there are e.g. 3 pies, they take 3×2 = 6 hours.
therefore the general constraint is
3.5x1 + 2x2 <= 70
I think the names "x1" and "x2" are confusing when writing this inequality.
I prefer to use x and y.
and then it would look like
3.5x + 2y <= 70

What is the approximate value of x in -2 In (x + 1)-3 = 7?
x = -0.993
x = 0.0067
x = -5
x = -6
Answer:
-0.993
Step-by-step explanation:
ADD 3 and DIVIDE by -2 to get the natural log expression by itself on the left.
Then convert to an exponential equation. Ln means that the base is e (e is a special number,but in fact, just a number)
e^(-5) -1 can be calculated on a calculator. There is usually an e^x button, then enter -5 exponent. Lastly subtract one.

How to find the solid of revolution enclosed by two functions
Let be [tex]f(x) = e^{\frac{x}{6} }[/tex] and [tex]g(x) = e^{\frac{35}{6} }[/tex], whose points of intersection are [tex](x_{1},y_{1}) =(0,1)[/tex], [tex](x_{2}, y_{2}) = (35, e^{35/6})[/tex], respectively. The formula for the solid of revolution generated about the y-axis is:
[tex]V = \pi \int\limits^{e^{35/6}}_{1} {f(y)} \, dy[/tex] (1)
Now we proceed to solve the integral: [tex]f(y) = 6\cdot \ln y[/tex]
[tex]V = \pi \int\limits^{e^{35/6}}_{1} {6\cdot \ln y} \, dy[/tex] (2)
[tex]V = 6\pi \int\limits^{e^{35/6}}_{1} {\ln y} \, dy[/tex]
[tex]V = 6\pi \left[(y-1)\cdot \ln y\right]\right|_{1}^{e^{35/6}}[/tex]
[tex]V = 6\pi \cdot \left[(e^{35/6}-1)\cdot \left(\frac{35}{6} \right)-(1-1)\cdot 0\right][/tex]

Explanation:
The adjacent angles of a parallelogram always add to 180
D+E = 180
(9x+15)+(6x) = 180
15x+15 = 180
15x = 180-15
15x = 165
x = 165/15
x = 11
Then we use this to find angle D
D = 9x+15 = 9*11+15 = 99+15 = 114
note that
E = 6x = 6*11 = 66
and
D+E = 114+66 = 180
to help confirm our answer.
Answer:
114
Angles in Quadrilateral adds to 360
2 x (9x+15) + 2 x (6x) = 360
18x + 30 +12x =360
30x + 30 = 360
-30
30x =330
÷30
x=11
Substitute value of x into Angle D
9x+15 will be 9 x 11 + 15 = 114
Thus, the answer is 114
