if i got paid 10 dollars an hours and wrk for 7 hours a day how much would i make a week including mon-fri. but got in a car crash and died how much would my bill be to pay.
So first, lets caculate how much you get in one day
-------------------------------------------------------------------------------------------
In one day..
10x7= 70$
So, in one day you make 70$.
-------------------------------------------------------------------------------------------Since we make 70$ in one day, we need to find out if we worked all week.
70x7 = 490$
So in one week,we make $490.

The function h(x) = x2 +3 and g(x) = x2 – 6. If g(x) = h(x) + k, what is the value of k?
Answer:
g(x) = x² - 6
h(x) = x² + 3
g(x) = h(x) + k
x² - 6 = (x² + 3) + k
x² - 6 = x² + 3 + k
- x² - x²
-6 = 3 + k
- 3 - 3
-9 = k
The value of k is -9.

Mary made $144 for 8 hours of work.
At the same rate, how much would she make for 12 hours of work?
Answer:
$216
Step-by-step explanation:
Find how much Mary made per hour by dividing 144 by 8 to get 18. Then, multiply that number by 12 which $216
Answer:
$216
Step-by-step explanation:
First, find out what Mary makes every hour. To find this, we divide 144 by 8.
144/8 = $18
This means that Mary makes $18 per hour.
Now, we find out how much Mary would make if she worked for 12 hours:
x = # of hours worked
18n
18(12)
$216
Therefore, Mary would make $216 in 12 hours.

Triangle EFG has an area of 70 m².
EF: FG= 1:2 and angle EFG = 40°.
(a) Calculate EF.
The measure of length EF is the triangle EFG has an area of 70 m² is 7.38m
How to calculate the area of a triangle?A triangle is a 2-dimensional shape with 3 sides and angles. The formula for calculating the area of a triangle is expressed as:
A = (EF)(FG) sin theta
If the ratio of EF to FG is 1:2, then FG = 2EF
A = (EF)(2EF) sin theta
70 = 2EF²sin40
70 = 1.2856EF²
EF² = 54.474
EF = 7.38m
Hence the measure of length EF is the triangle EFG has an area of 70 m² is 7.38m

Step-by-step explanation:
Miguel cabrera has had 369 at bats, and he has 127 hits and 21 home runs. (note: the home runs are included in the hits data.) if he is challenged to a batting battle, what is the expected score of each at bat if he earns 1 point for each hit that is not a home run and 5 points for each home run?
The expected score of each at bat if he earns 1 point for each hit that is not a home run and 5 points for each home run is 0.57
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
Number of bats = 369
Number of hits = 127
Number of home runs = 21
The probability of a hit:
[tex]=\frac{127}{369}[/tex] (includes home run)
The probability of home run:
[tex]=\frac{21}{369}[/tex]
The probability of hit run(without home run)
[tex]=\frac{127}{369}-\frac{21}{369}[/tex]
[tex]=\frac{106}{369}[/tex]
The probability of no hit:
[tex]=\frac{369-127}{369}[/tex]
[tex]=\frac{242}{369}[/tex]
For home run, the score will be 5 points.
If not, a home run score will be 1 points.
If Miguel does not get hit, score will be zero point.
Expected value of Miguel hit at each bat is (without home run):
For 5 hit:
[tex]=\frac{106}{369}[/tex]
For 21 home runs, the points will be 21×5 = 105 (5 points for each home run)
The expected value for this:
[tex]\frac{105}{369}[/tex]
Adding both expected hits, we get:
[tex]=\frac{106}{369}+\frac{105}{369}[/tex]
[tex]=\frac{211}{369}[/tex]
= 0.571 ≈ 0.57
Thus, the expected score of each at bat if he earns 1 point for each hit that is not a home run and 5 points for each home run is 0.57

A cylinder has a height of $10$ and a radius of $3.$ Determine the total surface area, including the two ends, of the cylinder.
Check the picture below.
[tex]\textit{surface area of a cylinder}\\\\ SA=2\pi r(h+r)~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=3\\ h=10 \end{cases}\implies \begin{array}{llll} SA=2\pi (3)(10+3) \\\\\\ SA=6\pi (13)\implies SA=78\pi \\\\\\ SA\approx 245.04 \end{array}[/tex]
Answer:
[tex]78\, \pi[/tex].
Step-by-step explanation:
A cylinder of height [tex]h[/tex] and radius [tex]r[/tex] could be unrolled into:
two identical circles, one for the top and one for the bottom, andone rectangle, for the side.The radius of each circle is the same as the radius of the cylinder, [tex]r[/tex].
The height of the rectangle is the same as the height of the cylinder, [tex]h[/tex].
The width of this rectangle would be [tex](2\, \pi\, r)[/tex], same as the circumferences of the two circles. The reason is that when this rectangle is rolled to build the cylinder, the top and bottom edges of the rectangle would wrap around the circumference of the two circles.
The area of each circle would be [tex]\pi\, r^{2}[/tex]. Note that there are two such circles, one at the top of the cylinder and one at the bottom.
With a height of [tex]h[/tex] and a width of [tex](2\, \pi\, r)[/tex], the area of the rectangle on the side would be [tex](2\, \pi\, r)\, h[/tex]. Add these areas up to find the total surface area of this cylinder:
[tex]\begin{aligned}& \text{(Surface Area of the Cylinder)} \\ =\; & (\text{Surface area of circle on the top}) \\ & + (\text{Surface area of circle at the bottom}) \\ & + (\text{Surface area of rectangle on the side}) \\ =\; & \pi\, r^{2} + \pi\, r^{2} + (2\, \pi\, r)\, h \\ =\; & 2\, \pi\, r^{2} + (2\, \pi\, r)\, h \end{aligned}[/tex].
For the cylinder in this question, [tex]h = 10[/tex] whereas [tex]r = 3[/tex]. The surface area of this cylinder would be:
[tex]\begin{aligned}& 2\, \pi\, r^{2} + (2\, \pi\, r) \, h \\ =\; & 2 \,\pi \times 3^{2} + (2\, \pi\times 3) \times 10 \\ =\; & 78\, \pi\end{aligned}[/tex].

x is directly proportional to the square of y.
.
y is directly proportional to the cube of z.
z= 2 when x = 32
Find a formula for r in terms of z.
The direct variation of x to y implies that x and y increases at the same time, and the formula of x in terms of z is [tex]x = 4z^3[/tex]
How to determine the formula for x?The direct proportion of x to y is represented as:
[tex]x\ \alpha\ y^2[/tex]
As an equation, we have:
[tex]x\ =\ ky^2[/tex]
The direct proportion of y to z is represented as:
[tex]y\ \alpha\ z^3[/tex]
As an equation, we have:
[tex]y\ =\ kz^3[/tex]
Square both sides
[tex]y^2 = k^2z^3[/tex]
Substitute [tex]y^2 = k^2z^3[/tex] in [tex]x\ =\ ky^2[/tex]
[tex]x =k^3z^3[/tex]
When z = 2, x = 32.
So, we have:
[tex]32 =k^3 * 2^3[/tex]
Evaluate
[tex]32 =k^3 * 8[/tex]
Divide both sides by 8
[tex]k^3 =4[/tex]
Substitute [tex]k^3 =4[/tex] in [tex]x =k^3z^3[/tex]
[tex]x = 4z^3[/tex]
Hence, the formula of x in terms of z is [tex]x = 4z^3[/tex]

[tex]\mathrm{Slope = \dfrac{1}{2}}[/tex]
Step-by-step explanation:
To find the slope of a graph, we use the formula below:
[tex]\mathrm{m =\dfrac{y\x_{2}-y\x_{1}}{x\y_{2}-x\y_{1}}}[/tex]
m = slope
(x1, y1) = coordinates of first point in the line
(x2, y2) = coordinates of second point in the line
Step 1: Find any two points on the line
Lets choose: (0, 3) and (2, 4)
Step 2: Put these points into the slope formula
[tex]\mathrm{m =\dfrac{y\x_{2}-y\x_{1}}{x\y_{2}-x\y_{1}}}[/tex]
Step 3: Substitute points into formula
[tex]\mathrm{m =\dfrac{4-3}{2-0}}[/tex]
Step 4: Subtract 3 from 4 and 0 from 2
[tex]\mathrm{m =\dfrac{1}{2}}[/tex]
----------------------------------------------------------------------------------------------------------
Another way you could easily do this is:
Step 1: Find two ponts on the line
For this problem, let's use (0, 3) and (2, 4)
Step 2: Then from the first point, how much do you need to go up and to the left or right to get to the second point
For this problem, we start on the on the point (0, 4) and go up by 1 and then to the right by 2
Step 3: Then you do rise over run to get the slope
The slope is rise over run:
Rise = 1
Run = 2
So, the slope is 1/2
