Answer
$150
Step-by-step explanation:
Since there are 12 months in year, you multiply 25 times 24 to get 600. 75% of 600 is 450, so then you do 600-450. The answer to that is 150.

Use the provided ruler to measure the length of the segment. What is the length of the segment to the nearest tenth of a centimeter?
The length of the segment is {Blank} centimeters.
The length of the segment to the nearest tenth of a centimeter is 105.0 cm
What is the length of the segment to the nearest tenth of a centimeter?The given parameter is the line segment
When the line segment is measured by a meter rule, we have the length to be
Length = 105 cm
When approximated to the nearest tenth, we have:
Length = 105.0 cm
Hence, the length of the segment to the nearest tenth of a centimeter is 105.0 cm

Find the equation of the quadratic function in vertex form, with vertex (-1, 8) that has a y-
intercept of 4 (which means it passes through the point (0,4)).
Answer:
The equation of the quadratic function is y = -4(x + 1)² + 8
Step-by-step explanation:
The vertex form of the quadratic function is y = a(x - h)² + k, where
a is constant(h, k) are the coordinates of the vertex of its graph∵ The vertex of the graph of the quadratic function is (-1, 8)
∴ h = -1 and k = 8
→ Substitute the values of h, k in the form of the equation above
∵ y = a(x - -1)² + 8
∴ y = a(x + 1)² + 8
→ To find a substitute x and y of the equation by the coordinates
of a point lies on the graph of the function
∵ The y-intercept is 4
→ That means the graph intersect the y-axis at point (0, 4)
∴ x = 0 and y = 4
∵ 4 = a(0 + 1)² + 8
∴ 4 = a(1)² + 8
∴ 4 = a(1) + 8
∴ 4 = a + 8
→ Subtract 8 from both sides
∵ 4 - 8 = a + 8 - 8
∴ -4 = a
→ Substitute the value of a in the equation
∴ y = -4(x + 1)² + 8
∴ The equation of the quadratic function is y = -4(x + 1)² + 8

A triangle has sides of lengths 12, 14, and 19. Is it a right triangle?
Answer:
a^2 + b^2 = c^2
C should equal to the longer side, which would be 19.
Plug in other two numbers for A and B.
12^2 + 14^2 = 19^2
Now see if it's correct. If it is, then it's a right triangle, if it's not then it isn't a right triangle.
144 + 196 = 361
340 = 361
It's not a right triangle.

geometry help please
=======================================================
Explanation:
Recall that midsegments are half as long as the side they are parallel to. In this case, midsegment PQ is parallel to segment GJ. This means PQ is half as long as GJ. Phrased another way, we can say GJ is twice as long as PQ.
So,
GJ = 2*PQ
Also, we can see that GR = RJ due to the triple tickmarks they share. This leads to GJ = GR+RJ = RJ+RJ = 2*RJ
Or in short,
GJ = 2*RJ
---------
In summary we can see that
GJ = 2RJGJ = 2PQequating both right hand sides leads to
2RJ = 2PQ
RJ = PQ
Because PQ is 10 units, this means RJ is also 10 units.
--------------------
Another way to see why PQ = RJ is to notice how triangles HPQ and QRJ are congruent triangles (use SAS to prove this). The corresponding pieces PQ and RJ are the same length, so PQ = RJ = 10.

One number is 4 times as large as another. The sum of their reciprocals is ½. What is the sum of the numbers? i need asap answer plssss
Answer:
The sum of the two numbers is 12.5
Step-by-step explanation:
First we write a system of equations.
One number is 4 times larger than the other.
y = 4x
The sum of their reciprocals is 1/2
1/x + 1/y = 1/2
Substitute
1/x + 1/4x = 1/2
1 + 1/4 = 1/2x
x = 2.5
Solve for other number
y = 4(2.5)
y = 10
The inverse of x is 2/5 or 4/10, and the inverse of y is 1/10. When added the sum is 5/10 or 1/2.

Find the value of the variable p and YZ if Y is between X and Z, XY=3p, YZ=2p-1, and XZ=6p-6
Using the segment addition postulate, the value of p = 5, and YZ = 9 units.
How to Apply the Segment Addition Postulate?Since point Y lies between points X and Z, the three points are collinear, therefore, based on the segment addition postulate, XY + YZ = XZ.
Given the following:
XY = 3p
YZ = 2p - 1
XZ = 6p - 6
Substitute
3p + 2p - 1 = 6p - 6
Add like terms
5p - 1 = 6p - 6
5p - 6p = 1 - 6
-p = -5
p = 5
YZ = 2p - 1
Plug in the value of x
YZ = 2(5) - 1
YZ = 9 units.

A carpenter wishes to make a rain gutter with a rectangular cross-section by bending up a flat piece of metal that is 18 feet long and 44 inches wide. The top of the gutter is open. What values of x, length of metal bent up, will give a cross-sectional area of at most 50 square inches? Round your answer to three decimal places.
Answer:
x = 20.996 , 1.002 square inches.
Step-by-step explanation:
We assume that the sides are bent at right angles
Dimensions of the given metal sheet are
Length = 18feet = 216 inches
Width = 44 inches
When we will bend the width part of the given metal sheet
let the bent length be x
so the cross sectional dimensions will be
width = 44-2x
length = x
Area = x(44-2x)
The given are should be at most 50 square inches
so the equation becomes
x(44-2x)[tex]\leq 50[/tex]
-2x^2 + 44x [tex]\leq 50[/tex]
[tex]2x^2 -44x +50\geq 0[/tex]
[tex]x^2 -22x +25\geq 0[/tex] (dividing the equation by 2)
upon solving the above quadratic equation we get
x = 20.996 , 1.002
both the solutions are possible.
Therefore we have the are using the values of x as 20.996 and 1.002 are
42.159968 and 42.079992 which is less than 50 square inches.

Laura's yard is in the shape of a square and a half-circle. She just got a puppy named Sprinkles for her birthday. In order to keep him safe, she wants to line the perimeter of her yard with a fence. How much fencing will she need to enclose the entire yard and keep Sprinkles from running away?
Answer:
The total perimeter she would need to fence would be:
4L + πr
Step-by-step explanation:
Since her yard is a square and half a circle, and she wants to fence the whole distance around the square and the half circle, then she needs to know the perimeter of a square and semicircle.
The perimeter of a square which is the distance around the square is given by 4L where L is the side length.
The perimeter of a circle, which is the circumference of a circle is 2πr, where r is the radius of the circle Therefore, half a circle would be 2πr/2 = πr.
The total perimeter she would need to fence would be:
4L + πr.

At King Kong High School, the average weight of senior boys is 168 lbs. with a standard deviation of 7 lbs. The average weight for senior girls is 117 lbs. with a standard deviation of 5 lbs. Suppose a new distribution is created by adding the boys' weights and the girls' weights together. Assuming that the weights for boys and girls are independent, which of the following is true?
I. The mean of this new distribution is 168 + 117.
II. The standard deviation of this new distribution is 5+ 7.
III. The variance of this new distribution is 52 + 72
A) I only
B) II only
C) I and II only
D) I and III only
E) I, II, and III
Answer:
I and III only. Got it correct on Stats test.
Thus, the mean of this new distribution is 168 + 117 and the standard deviation of this new distribution is 5+7. Therefore, option C is the correct answer.
Given that, at King Kong High School, the average weight of senior boys is 168 lbs.
What is standard deviation?Standard deviation is the positive square root of the variance. Standard deviation is one of the basic methods of statistical analysis. Standard deviation is commonly abbreviated as SD and denoted by 'σ’ and it tells about the value that how much it has deviated from the mean value.
Here, a new distribution is created by adding the boys' weights and the girls' weights together.
So, the new average weight of senior boys and girls
= 168+117
= 285 lbs
The new standard deviation is 5+7
= 12 lbs
Thus, the mean of this new distribution is 168 + 117 and the standard deviation of this new distribution is 5+7. Therefore, option C is the correct answer.
