Find the area of the shaded region
Answer:
12 sq. units
Step-by-step explanation:
The formula for finding the area of a triangle is a = 1/2bh, or 1/2 times base times height.
To do this, multiply the base (6) and height lengths (4). This gets you 24.
But we're not done. You must then multiply by 1/2, which is the same a dividing by 2/1 or 2. 24/2 = 12. Slap on the unit of measurement and you've got your answer.
I NEED HELP ASAP!!!PLEASE EXPLAIN THE ANSWER
Answer:
Below
Step-by-step explanation:
To find surface area, you can just find the area of each side and add them up!
11 ft x 9 ft x 2 = 198 ft^2 (this is the surface area of the front and back)
12 ft x 9 ft x 2 = 216 ft^2 (this is the surface area of the sides)
12 ft x 11 ft x 2 = 264 ft^2 (this is the surface area of the top and bottom)
Surface area = 198 + 216 + 264
= 678 ft^2
Hope this helps! Best of luck <3

Answer:
3744.64
Step-by-step explanation:
To know the answer to this question you need to know the formulas to find the volume of the cylinder and the rectangular prism. The volume of a cylinder is pi*r^2*h while the volume of the rectangular prism is l*w*h. The cylinder is 1808.64 cubic in while the rectangular prism is 1936 cubic. Together, they are 3744.64 cubic in.
Answer:
cylinder= A=πr²h
=3.14×4²×9
=452.16
rectangle=A=l×w×h
=19×11×11

You invested $8,307 into stocks of a company which
were priced at $13.71/sh. How many shares did you
purchase?
Answer:
606 shares
Step-by-step explanation:
Number of shares= (Total money spent)/(Each share price)
Number of share=(8307)/13.71=605.9≈606
1.) You plan to cut a board into 3 pieces to repair part of a railing. You are going to cut the two ends of the board off into two equal pieces that are 1.4 feet long, if the remaining piece needs to be 1.17 times longer than the each of the first two cuts what length board should you buy? Round to the nearest tenth.
2.) You are looking at your power bill for the month, you pay 13 cents per kilowatt-hour. Your power bill came out to $83.96 homes many KWH of energy were used in your house this month?
3.) you were looking at your power bill for the month, you pay nine cents per kilowatt hour. Running a 60 W lightbulb for one hour is .0 6 KWH, if you leave a light on all the time that has 5 lightbulbs in it how much would that cost in a 30 day month? answer in the form of $2.54 without the dollar sign
Here we have 3 general algebraic problems that we need to solve. Using simple reasoning we can solve these.
1) L = 4.4 ft
2) This month you used 645.85 KW-h in your home.
3)Cost = $19.44
1) You will buy a board of length L.
You will cut two pieces that are 1.4 ft long.
So at this point, the length of the board piece is:
L - 1.4ft - 1.4ft = L - 2.8ft.
Now, you want this to be 1.17 times longer than 1.4ft, then we need to solve:
L - 2.8ft. = 1.17*(1.4ft) = 1.638ft
L = 1.638ft + 2.8ft = 4.438ft
Rounding to the nearest tenth, we get:
L = 4.4 ft
This is the length of board you should buy.
2) Here we know:
You pay $0.13 per KW-h
This month, you pay a total of $83.96
The total number of KW-h you used is equal to the quotient between the total amount you paid and the price of a single KW-h, this is:
N = $83.96/$0.13 = 645.85
This month you used 645.85 KW-h in your home.
3) Here we know:
You pay $0.09 per KW-h.
Running the bulb for one hour consumes 0.06 KW-h
So, if you leave one of these lights on all day (24 hours) it would consume:
24*0.06 KW-h = 1.44 KW-h
If you instead leave 5 of these bulbs, you will consume 5 times that amount:
5*1.44 KW-h = 7.2 KW-h
This is in one single day, if you do this for 30 days, the total consumption is:
30* 7.2 KW-h = 216 KW-h
And you pay $0.09 for each one of these, then the cost is 216 times $0.09
Cost = 216*$0.09 = $19.44

Answer:
x = 57.2
Step-by-step explanation:
first : the third angle is (the sum of all angles in a triangle is always 180 degrees) : 180 - 90 - 40 = 50 degrees.
law of sines :
x/sin(50) = 48/sin(40)
x = 48 × (sin(50)/sin(40)) = 57.2

Use the parabola tool to graph the quadratic function f(x)=(x−5)2+1 . Graph the parabola by first plotting its vertex and then plotting a second point on the parabola.
Answer:
Vertex (5, 1)
Example of second point (4, 2)
Step-by-step explanation:
THe equation given is in vertex form so it will be easy to find the vertex
(x-5)^2+1
Vertex is at h,k and vertex form is y = a(x−h)^2 + k
x coordinate will be 5
y coordinate will be 1
vertex - (5, 1)
You can plot a second point by plugging in any number into the x or y
For example, if you set x to be 4,

A. 40°
B. 70°
C.80°
D. 120°

Answer: x = 150
Step-by-step explanation:
See the liner pair of angle 70 will be 110 degrees.
Then using angle sum property third angle will be
Third angle = 180 - 150
Third angle of the triangle = 30
Now linear pair of the 30 degree angle
30+x = 180
x = 180-30
x = 150

What is the linear pair of angles?Linear pair of angles are formed when two lines intersect each other at a single point.
The angles are said to be linear if they are adjacent to each other after the intersection of the two lines.
BY applying linear pair angles;
[tex]\rm \angle 1+\angle 2=180\\\\70 +\angle 2=180\\\\ \angle 2=180-70\\\\ \angle 2=110\\\\[/tex]
The sum of the three angles is 180.
[tex]\rm \angle 1+\angle 2+ \angle 3=180\\\\ 110+40 +\angle 3=180\\\\150+\angle 3= 180\\\\\angle 3=180-130\\\\\angle 3=30[/tex]
The measure of the value of angle x is;
[tex]\rm 30+x = 180\\\\x = 180-30\\\\x = 150[/tex]

Answer:
the slope is -1/4 throughout the line.
Step-by-step explanation:
the slope of a line never changes anywhere on the line. otherwise it would not be a line.
the slope is expressed by the ratio y/x indicating how many units y changes, when x changes by a certain number of units.
and in this graphic, when x changes 4 units to the right (positive), y changes 1 unit down (negative).
therefore -1/4
Answer:
3rd option
Step-by-step explanation:
The line has the same slope over the whole line
Calculate slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = O (0, 0) and (x₂, y₂ ) = B (- 12, 3)
m = [tex]\frac{3-0}{-12-0}[/tex] = [tex]\frac{3}{-12}[/tex] = - [tex]\frac{1}{4}[/tex]
The slope is - [tex]\frac{1}{4}[/tex] throughout the line

the absolute value simply removes a negative sign, if there is one. if there is no negative sign, it leaves the argument untouched.

Step-by-step explanation:
Y=
[tex]y = 10 - 8x \\ put \: this \: in \: the \: second \: equation \\ 2(10 - 8x) - 4x = 40 \\ 20 - 16x - 4x = 40 \\ 20 - 20x = 40 \\ - 20 = 20x \\ x = - 1 \\ put \: the \: value \: of \: x \: in \: th \: first \: equation \\ y = 10 - 8( - 1) \\ y = 10 + 8 \\ y = 18[/tex]
Hence, x=-1 and y=18
Answer:
(- 1, 18 )
Step-by-step explanation:
Given the equations
y + 8x = 10 ( subtract 8x from both sides )
y = 10 - 8x → (1)
2y - 4x = 40 → (2)
Substitute y = 10 - 8x into (2)
2(10 - 8x) - 4x = 40 ← distribute and simplify left side
20 - 16x - 4x = 40
20 - 20x = 40 ( subtract 20 from both sides )
- 20x = 20 ( divide both sides by - 20 )
x = - 1
Substitute x = - 1 into (1) for corresponding value of y
y = 10 - 8(- 1) = 10 + 8 = 18
solution is (- 1, 18 )

The answer to this problem
Answer:
x = 12°
y = 1.4 cm
Step-by-step explanation:
1. Because the two triangles are similar, their corresponding angles are congruent.
so
3x + 14 = 50
Subtract 14 from both sides
3x = 36
Divide both sides by 3
x = 12
x = 12° (remember units)
Check work:
3(12) + 14 = 50
36 + 14 = 50
50 = 50
2. Because the two triangles are similar, their corresponding sides are in equal proportion.
Two sides of triangle ABE are
5.6 and 4
And two corresponding sides of triangle ACD are
5.6 + y and 5
So
5.6 / 4 = (5.6 + y) / 5
Cross multiply
5.6 * 5 = 4(5.6 + y)
Multiply 5.6 * 5 on the left
28 = 4(5.6 + y)
Distribute the 4 to each term
28 = 4*5.6 + 4*y
Simplify the right side
28 = 22.4 + 4y
Subtract 22.4 from both sides
5.6 = 4y
Divide by 4 on both sides
1.4 = y
y = 1.4 cm (remember units)
Check our work:
5.6/4 = (5.6 + 1.4)/5
1.4 = 7/5
1.4 = 1.4
