A sheet of bad paper is cut into 12 equal parts. What percent of the whole is 3 parts? This is easy, dont be afraid to ask for help
Answers
Answer: 25percent
Step-by-step explanation: Divide 12 by 3 and you'll get 4.
That means 1/4 or a quarter of the 12 is 3.
(Convert the fraction to its percentage form)
1/4 or 1 divided by 4 equals 0.25
Multiply 0.25 by 100 and you'll get 25%
Note: you can convert easier from decimal form to percentage form by moving the decimal place two spaces to the right

Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers
cost $0.05 each. How much would Mrs. Algebra's single order be? Use the expression below
to calculate the total.
Answers
Given :
Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers cost $0.05 each.
To Find :
How much would Mrs. Algebra's single order be.
Solution :
Total price paid by Mrs. Algebra = Price of pencil + price of ruler + price of calculator + price of eraser.
T = $(0.10 + 0.49 + 12.99 + 0.05)
T = $13.63
Therefore, Mrs. Algebra's single order cost is $13.63 .
Hence, this is the required solution.

Solve for the value of x in this equation: 146=2+7x+5x
Answers
Answer:
x=12
Step-by-step explanation:
First combine like terms
146=2+12x
Then I like to put it into y=mx+b form.
146=12x+2
Next you subtract 2 from both sides.
146-2=12x+2-2
144=12x
Finally you divide 12 on both sides and in the end you get x=12. Hope this helps.

[tex](9s + 8)° + 37° = 180°[/tex]
Because they make straight line.

[tex]9s + 45 = 180[/tex]
Subtract sides 45
[tex]9s + 45 - 45 = 180 - 45[/tex]
[tex]9s = 135[/tex]
Divide sides by 9

The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 31 m. Find the height of the building. If
necessary, round your answer to the nearest tenth.
Answers
Answer:
16.9 m
Step-by-step explanation:
The diagram given that represents this situation is a right triangle.
The height of the building can be found using the pythagorean theorem, a² + b² = c².
Where,
a = 26 m
b = height of the building = h
c = 31 m
Plug in the values into the formula
Thus:
[tex] 26^2 + b^2 = 31^2 [/tex]
[tex] 676 + b^2 = 961 [/tex]
Subtract 676 from each side
[tex] b^2 = 961 - 676 [/tex]
[tex] b^2 = 285 [/tex]
Square both sides
[tex] b = \sqrt{285} [/tex]
[tex] b = 16.9 m [/tex] (nearest tenth)

A bowling ball is dropped from a height of 50 feet

h(t)=
b. Find the height of the bowling ball after 1 second.
c. How long does the bowling ball take to hit the ground? Round your answer to the nearest hundredth of a second.
Answers
Answer:
A. The function that gives the height of the bowling ball after t seconds is [tex]h(t) = 50-16.087\cdot t^{2}\,\,\,[ft][/tex].
B. The height of the bowling ball after 1 second is 33.913 feet.
C. The bowling ball will take approximately 1.763 seconds to hit the ground.
Step-by-step explanation:
A. From Physics we notice that ball experiments a free-fall, which is an uniform accelerated motion due to gravity and where air friction and effects of the Earth's rotation are neglected. The height of the ball is described by the following kinematic equation:
[tex]h(t) = h_{o}+v_{o}\cdot t +\frac{1}{2}\cdot g \cdot t^{2}[/tex] (1)
Where:
[tex]h_{o}[/tex] - Initial height of the ball, measured in feet.
[tex]v_{o}[/tex] - Initial velocity of the ball, measured in feet per second.
[tex]t[/tex] - Time, measured in seconds.
[tex]g[/tex] - Gravitational acceleration, measured in feet per square second.
If we know that [tex]h_{o} = 50\,ft[/tex], [tex]v_{o} = 0\,\frac{ft}{s}[/tex] and [tex]g = -32.174\,\frac{ft}{s^{2}}[/tex], then the function that gives the height of the bowling ball after t seconds is:
[tex]h(t) = 50-16.087\cdot t^{2}\,\,\,[ft][/tex] (2)
The function that gives the height of the bowling ball after t seconds is [tex]h(t) = 50-16.087\cdot t^{2}\,\,\,[ft][/tex].
B. If we know that [tex]t = 1\,s[/tex], then the height of the bowling ball is:
[tex]h(1) = 50-16.087\cdot (1)^{2}[/tex]
[tex]h(1) = 33.913\,ft[/tex]
The height of the bowling ball after 1 second is 33.913 feet.
C. The bowling ball hits the ground when height is zero. Let equalize (1) to zero and solve the resulting expression:
[tex]50-16.087\cdot t^{2} = 0[/tex]
[tex]16.087\cdot t^{2} = 50[/tex]
[tex]t \approx 1.763\,s[/tex]
The bowling ball will take approximately 1.763 seconds to hit the ground.

Slope = 2/7; y intercept = 0 and they want me to write it in slope intercept form
Answers
m is the slope and b is the variable for the y-intercept. All you have to do is to substitute the numbers to the corresponding variables.
So the answer would be: y = 2/7x + 0 or y = 2/7x
Hello again! To do this you must remember that slope intercept form is y=mx+b. m equals slope while b equals y intercept. Our slope is 2/7 while our y intercept is zero. Now, plug them in and you should get the equation y=2/7x+0. We have a zero at the end so we remove the + and zero and get y=2/7x.

how do you figure out the square root of z^2+8z+16?
Answers
Step-by-step explanation:
Hey there!
Given;
[tex] = \sqrt{ {z}^{2} + 8z + 16} [/tex]
Looking through question, we can bring it to perfect square to remove the (√) sqrt.
[tex] \sqrt{( {z)}^{2} + 2.4x + {4}^{2} } [/tex]
We made this to bring it in the form of (a+b)^2. As (a+b)^2 = a^2 + 2.a.b + b^2.
Now, our question looks like similar to the formula.
So, We can write it as:
[tex] \sqrt{( {z + 4)}^{2} } [/tex]
Now, we can cancel (√) and (^2). And we get
= z + 4

A long-distance telephone company charges a rate of cents per minute or a -cent minimum charge per completed call, whichever is greater. Find the cost, in cents per minute, for a -minute call.
Answers
Answer: 50 cents
Step-by-step explanation:
Company charges 8 cents per call and the call in question is 3 minutes. Cost is;
= 3 * 8
= 24 cents
Company however stipulates that a call is 8 cents per minute or a 50-cent minimum charge per completed call, whichever is greater.
50 cents is greater than the per minute total charge of 24 cents so the cost will be 50 cents.
