find the area of triangle qpm. round the answer to the nearest tenth. a. 5.2 square units b. 6.3 square units c. 6.5 square units d. 12.6 square units

We need to solve for the angles of the smaller triangle in order to solve for the angle of the larger triangle which would help us solve the missing measurement of a side.
Given:
51 degrees.
Cut the triangle into two equal sides and it forms a right triangle. All interior angles of a triangle sums up to 180 degrees.
180 – 51 – 90 = 39 degrees
39 degrees * 2 = 78 degrees.
Angle Q is 78 degrees.
In the bigger triangle, 4.3 is the hypotenuse. We need to solve for the measurement of the long leg which is the opposite of the 78 degree angle.
We will use the formula:
Sine theta = opposite / hypotenuse
Sin(78 deg) = opposite / 4.3
Sin(78 deg) * 4.3 = opposite
4.21 = opposite. This is also the height of the triangle.
Area of a triangle = ½ * base * height
A = ½ * 3units * 4.21units
A = 6.315 square units.

Answer: [tex]\frac{3y(2x-1)}{x(x-2)}[/tex]
Step-by-step explanation:
Given problem to simplify is [tex]\frac{\frac{15xy^2}{x^2-5x+6} }{\frac{5x^2y}{2x^2-7x+3} } \\\\=\frac{15xy^2}{x^2-5x+6}\cdot\ \frac{2x^2-7x+3} {5x^2y}............\text{(by fractional division property,the denominator invert and its reciprocal multiply to numerator)}\\\\=\frac{15xy^2}{(x-3)(x-2)}\cdot\frac{(x-3)(2x-1)} {5x^2y}.........\ \text{(factorizing quadratic equation)}[/tex]
[tex]=\frac{3y(2x-1)}{x(x-2)}........\text{(cancelling like terms with same degree and coefficients from numerator and denominator)}[/tex]
so the simplified form of the given problem is [tex]\frac{3y(2x-1)}{x(x-2)}[/tex]
Find the slope and y-intercept of the line. y = 7/5x – 3
Answers
m = slope
b = y intercept
m = 7/5
b = -3 or (0,-3).
Answer:
Slope is [tex]\frac{7}{5}[/tex]
y-intercept is -3
Step-by-step explanation:
Given equation of line,
[tex]y=\frac{7}{5}x-3[/tex]
Since, the slope intercept form of a line is y = mx + c
Where, m is the slope of the line,
By comparing,
[tex]m = \frac{7}{5}[/tex]
Hence, the slope of the given line is [tex]\frac{7}{5}[/tex]
Now, for y-intercept,
x = 0,
[tex]y=\frac{7}{5}(0) - 3 = -3[/tex]
Hence, the y-intercept of the line is -3.

D)2n+5
Answers
n*2 = 2n [and n packages containing two pens each]
So the total number of pens that he bought is 2n+5
This is because you know how many packages of 5 pens he bought which is 1. So that stays the same. you are trying to figure out how many packages of 2 pens he bought so that is a variable. so to find the total number of pens it is 2n+5.

What is the solution to the equation x + 8.5 = 64.5? 7.6 48 56 73
Answers
x + 8.5 = 64.5
- 8.5 - 8.5
---------------------------
x = 56
x + 8.5 = 64.5
Reorder the terms:
8.5 + x = 64.5
Solving
8.5 + x = 64.5
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8.5' to each side of the equation.
8.5 + -8.5 + x = 64.5 + -8.5
Combine like terms:
8.5 + -8.5 = 0.0
0.0 + x = 64.5 + -8.5
x = 64.5 + -8.5
Combine like terms: 64.5 + -8.5 = 56
x = 56
Simplifying x = 56

Answers
For this problem,let's divide each row of values to get the ratio. The ratio for all of this pair of values must coincide with each other. The solution is as followsL
Hot Popcorn Corn/Caramel Corn
5/8 = 5/8
10/16 = 5/8
15/24 = 5/8
Therefore, the ratio is 5/8. It can also be in decimal form which is equal to 0.625.

Answers
Part A:(This table is a three by three table, with the first top two sections being liked apple juice and didn't like apple juice, and the first left two sections being liked orange juice and didn't like orange juice. The end sections are totals.)
No 27 45 72
Total 35 55 100
Part B:(What percentage of the total people did not like either apple or orange juice?)
25 people did not like either apple or orange juice so 25/100 is 25%.
Part C:(Do the people surveyed have more dislike for apple juice than orange juice? Justify your answer.)
There were a total of 28 people that liked orange juice against a total of 35 people that liked apple juice, so it is safe to say that out of the 100 surveyed there was more dislike for orange juice than apple juice.
Answer:
Part A: A = 8
B = 20
C = 28
D = 35
E = 37
F = 72
G = 43
H = 57
I = 200
Part B: 18.5%
Part C:
D = People who do not like Orange Juice
B = People who do not like Apple Juice
I use the values of B and D because these are the values that represent dislike for that juice, and also because adding them together creates a value for not liking either juice.
D = 35
B = 20
So there is a greater dislike for Orange Juice.

If f(x)=2x-4, find f(q+1)
please show your work!
Answers
If the function f(x) = 2x-4, the function f(q + 1) = 2q - 2
What is a function?A function is a mathematical equation that shows the relationship between two variables.
Since if f(x)=2x-4, to find f(q+1), we proceed as follows.
Since we have the function f(x) = 2x - 4, and we want to find f(q + 1). To find the function f(q + 1), we substitute x = q + 1 into the equation. so, we have that
f(x) = 2x - 4
When x = q + 1, we have that
f(x) = 2x - 4
f(q + 1) = 2(q + 1) - 4
Expanding the brackets, we have that
f(q + 1) = 2q + 2 - 4
= 2q - 2
So, f(q + 1) = 2q - 2

A wire that is 22 feet long connects the top of a pole to the ground. The wire is attached to the ground at a point that is 10 feet from the base of the pole.
What is the height of the pole? Round to the nearest hundredth.
12.00 feet
19.60 feet
24.17 feet
38.40 feet
Answers
Solution:
Length of wire = 22 feet =AB
Distance between the point where wire is attached to the ground from the point on the ground where pole is fixed= 10 feet=OB
In Right Δ O A B
By Using pythagoras theorem
O A² + OB² = AB²
O A² +10²= 22²
O A²= 484 - 100
O A²= 384
O A= √384= 19.60 (Approximately)
So, the height of pole to nearest hundredth = 19.60 feet
The height of the pole is 19.60 ft
The situation forms a right angle triangle.
Right angle triangleRight angle triangle have one of its sides as 90 degree.
The length of the wire is the hypotenuse of the triangle formed.
The distance of the wire attached to the ground to the base of the pole is the adjacent side of the triangle.
The height of the pole can be found using Pythagoras theorem.
c² = a² + b²
22² - 10² = b²
b² = 484 - 100
b = √384
b = 19.5959179423
b = 19.60 ft

A researcher is interested in estimating the average salary of police officers in a large city. She wants to be 99% confident that her estimate is correct. If the standard deviation is $1050, how large a sample is needed to get the desired information and to be accurate within $200?
Answers
σ = $1050, ppulatin standard deviation
99% confidence interval
Accuracy = +/- $200
The accuracy is given by
z*(σ/√n)
where
z* = 2.576 for 99% confidence level (from tables)
n = sample size
Therefore
2.576(1050/√n) = 200
√n = (2.576*1050)/200 = 13.524
n = 182.9
Answer: The sample size is 183
