Answer:
8/2
Step-by-step explanation:
So you'll want to multiply the number of keys for each by the number below them. So 2/8 has 4 "x"s, so you'll want to multiply (2/8)*4 and so on.
4*(2/8)=1
4*(3/8)=12/8=>1.5
1*(4/8)=1/2
Add those all up to get 4, which is also 8/2.

What is a triangle?A triangle is a two - dimensional figure with three sides and three angles.The sum of the angles of the triangle is equal to 180 degrees.∠A + ∠B + ∠C = 180°Given is to find the length of the altitude of the equilateral triangle.
An equilateral triangle is a triangle whose all sides are equal. All the angles of a given equilateral triangle are 60 degrees.
The length of the altitude of the equilateral triangle can be found out using the Pythagoras theorem.
Draw a median from one vertex on the opposite side to that vertex and apply Pythagoras theorem to one of the right triangle.
We can find the length of the altitude to be -
L = a√3/4
Therefore, the length of the altitude of the equilateral triangle is a√3/4 units.

Answer:
1. VW = 22
2. x = 87
Step-by-step explanation:
Question 1:
SU = 11 (given)
SU = ½(VW) => midsegment theorem
11 = ½(VW) => Substitution
Multiply both sides by 2
2*11 = VW
VW = 22
Question 2:
UV = x + 13
RT = x - 37
RT = ½(UV) => Midsegment Theorem
x - 37 = ½(x + 13) => Substitution
Multiply both sides by 2
2(x - 37) = x + 13
2x - 74 = x + 13
2x - 74 + 74 = x + 13 + 74
2x = x + 87
2x - x = x + 87 - x
x = 87

Explain how to find the area of the composite figure above in your explanation be sure to include the formulas you will need to solve the problem
Answers
9514 1404 393
Answer:
40.5 square inches
Step-by-step explanation:
The figure appears to be a trapezoid with bases 15 inches and 12 inches, and a height of 3 inches. The formula for the area of a trapezoid is useful in this case:
A = 1/2(b1 +b2)h
A = (1/2)(15 in +12 in)(3 in) = (1/2)(27 in)(3 in) = 40.5 in²
The area of the composite figure is 40.5 square inches.
__
Additional comment
You get the same answer if you divide the figure into a rectangle and a triangle. The rectangle is 3 in high by 12 in long, so has an area of ...
A = bh = (12 in)(3 h) = 36 in²
The triangle has a base of (15 -12) = 3 in, and a height of 3 in. It has an area of ...
A = 1/2bh = 1/2(3 in)(3 in) = 4.5 in²
Then the total area is the sum of the rectangle and triangle areas:
figure area = 36 in² +4.5 in² = 40.5 in²
What is the fewest number of quarters, nickels, and pennies that can be fairly exchanged for 2 quarters, 6 nickels, and 9 pennies?
Answers
Answer:
Your answer is 3 quarters, 2 nickels, and 4 pennies
Step-by-step explanation:
2 quarters plus 6 nickels plus 9 pennies is equal to 89 cents. So if we subtract 75(3 quarters) we get 14 which is less than 25 therefore we must only use nickels and pennies from now on. If we take 14 and subtract 10(2 nickels) we get 4 which less than 5 leaving us only to use pennies, which one a piece so it must be 4 pennies. Hope this helps!

Find the work W done by a force of 3 pounds acting in the direction 60° to the horizontal in moving an object 4ft (0,0) to (4,0)
Answers
Answer:
[tex]\frac{3}{2}i + \frac{3\sqrt{3} }{2}[/tex]j
Step-by-step explanation:
The work done by the force in moving the object is 10 ft-lb.
What is force?Force is an influence or interaction that can change the motion or shape of an object with mass.
It can be described as a push or a pull that has both magnitude and direction.
Force is equal to the product of the mass of the object and its acceleration.
Given,
F = 3 p
d = 4 ft
The work formula:
W = F x d
W = 4 p x cos 60° x 5 ft
= 10 ft lb.
Hence, the work done by the force in moving the object is 10 ft-lb.

Answer:
Mexican Gulf Output of a Oil-Rig
Based on 57% red flag days, Joe, the retired statistician, who watches from the shore for the red flag every day, cannot conclude that the oil-rig is operating at a non-ideal condition most of the time, but more of the time.
Step-by-step explanation:
Ideal output of a particular oil-rig, at least = 2,000 barrels per day
When output is lesser than 2,000, a red flag is raised by the foreman
Number of days counted = 28
Number of days when red flag was raised = 16
Proportion of days when the red flag was raised = 16/28
= 0.57

Sully is having a party and wants to fill his swimming pool. If he only uses his hose, it takes 3 hours more than if he only uses his neighbor's hose. If he uses both hoses together, the pool fills in 5 hours. How long does it take for each hose to fill the pool (in hr)?
Answers
Answer:
It takes the neighor's hose 3 hours to fill the pool and it takes Sully's hose 6 hours to fill the pool if each filled alone.
Step-by-step explanation:
This is a work problem, and the way these are done is to figure the amount that each can do based on how much can get done in a single hour.
First thing, in order to have only one variable, we have to put one hose in terms of the other hose.
We know that it takes the neighbor's hose a certain amount of time (there's our unknown) to fill the pool and that it takes Sully's hose that same time plus 3 hours.
neighbor's hose can get the job done in x time
Sully's hose can get the job done in x + 3 time
Now we will figure out how much each can do in a single hour.
If the neighbor's hose takes x hours to fill the pool, then it can get
of the pool filled in 1 hour.
If Sully's hose takes x + 3 hours to fill the pool, then it can get
of the pool filled in 1 hour.
The sum of these takes 2 hours total and 1/2 of the pool gets filled in 1 hour.
Our equation then is:
This equation states in words:
"the amount of the pool that the neighbor's hose can fill in an hour plus the amount of the pool that Sully's hose can fill in an hour will fill half the pool".
Solving for x will give us that time.
Begin to solve this by finding the LCM of those denominators and getting rid of the fractions by reducing. The LCM will be 2x(x + 3). Multiplying each term by that LCD looks like this:
In the first term the x's cancel out, in the second term the (x + 3) cancels out, and in the last term the 2's cancel out leaving us with:
and simplifying gives us:
This is a quadratic that will have to be factored to solve for those values of x. Combine like terms and get everything on one side to get:
Factor this however you find easiest to get the values:
x = 3 hours and x = -2 hours
We all know that the 2 things in math that will never EVER be negative are times and distances/measures, so we can disregard the -2 and say that
x = 3 hours.
To answer our question, then;
It takes the neighbor's hose 3 hours to fill the pool; it takes Sully's hose 3+3 hours = 6 hours to fill the pool.
