Use the figure at the right to answer questions 9-12.
Answer:
9.) 5x - 18 = 4x + 7 10.) x = 25 11.) m∠MNQ = 107° 12.) m∠MNR = 73°
Step-by-step explanation:
9. & 10.)
∠MNQ and ∠RNP are vertical angles meaning they are equivalent to each other. Knowing that, we can set their values equal to each other and solve for x.
5x - 18 = 4x + 7 (Given)
x - 18 = 7 (Subtract 4x on both sides)
x = 25 (Add 18 on both sides)
Therefore, we know the equation is 5x - 18 = 4x + 7 and we know that x = 25.
Now we can solve for the angles.
11.)
5(25) - 18
125 - 18 = 107
Therefore, m∠MNQ = 107°.
12.)
∠MNR and ∠MNQ are supplementary angles meaning their angles will add up to 180°
∠MNR + 107 = 180
∠MNR = 73
Therefore, m∠MNR = 73°.

Emelina loaded 96 trucks in 8 hours. At that rate, how many trucks
would she load in 15 minutes?
Answer:
3
Step-by-step explanation:
60 × 8 = 480 (mins)
96 (trucks) = 480 (mins)
÷32 (I got this number by dividing 480 by the desired amount of mins which was 15)
3 = 15
So 3 trucks would have been loaded in 15 mins

solve: x2 + 8x - 9 = 0
please i need it urgently
Answer:
x = 1 or x = -9
Step-by-step explanation:
Solve for x over the real numbers:
x^2 + 8 x - 9 = 0
Hint: | Solve the quadratic equation by completing the square.
Add 9 to both sides:
x^2 + 8 x = 9
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 16 to both sides:
x^2 + 8 x + 16 = 25
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x + 4)^2 = 25
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x + 4 = 5 or x + 4 = -5
Hint: | Look at the first equation: Solve for x.
Subtract 4 from both sides:
x = 1 or x + 4 = -5
Hint: | Look at the second equation: Solve for x.
Subtract 4 from both sides:
Answer: x = 1 or x = -9

csc(0)=
sec(0)=
cot(0)=
Answer:
Step-by-step explanation:
we need that theta angle .. soooo.... use SOH CAH TOA to remind yourself how the trig functions fit on the triangle.....
since we have all 3 side any one of the above trig functions would work. as a side note.. Tan is limited to the 1st quadrant on a calculator.. so maybe Cos is a good choice. although it would work in this case....
sooo ....
Cos(Ф) = Adj / Hyp
Ф = arcCos( 24 /25)
Ф ≈16.26°
I don't have csc on my calculator but I know that 1/sin = csc sooo
csc(16.26)=1/sin(16.26) ≈ 3.57
sec(16.26)= 1/cos(26.26) ≈ 1.041
cot(16.26) = cos(16.26) / sin(16.26) ≈3.476
Answer:
csc(0)= 25/7
sec(0)= 25/24
cot(0)= 24/7

A function rule takes an input(x) and coverts into an output(y), by increasing 4 times the inpuy by 36. Write an equation for the rule and determine the output for this rule when the input is 3
Answer:
[tex]y = 4x + 36[/tex]
[tex]y = 48[/tex] when [tex]x = 3[/tex]
Step-by-step explanation:
Given
x = input
y = output
Required
Determine the equation of y
The process to get y is as follows:
Multiply x by 4: x * 4
Increase the result by 36: x * 4 + 36
Hence:
[tex]y = x * 4 + 36[/tex]
[tex]y = 4x + 36[/tex]
Solving y when x = 3
Substitute 3 for x in [tex]y = 4x + 36[/tex]
[tex]y = 4 * 3 + 36[/tex]
[tex]y = 12 + 36[/tex]
[tex]y = 48[/tex]

Residents of three counties were polled to find the percentage of residents who are Republican or Democrat. A 4-column table with 4 rows. The first column has no label with entries county 1, county 2, county 3, total. The second column is labeled Democrat with entries 4,050; 3,925; 2,100; 10,075. The third column is labeled Republican with entries 2,470; 6,010; 5,950; 14,430. The fourth column is labeled total with entries 6,520; 9,935; 8,050; 24,505. Find the following relative frequencies to the nearest tenth of a percent. Republican residents of County 1: % Democratic residents of County 1: % Total Republican residents: % Total Democratic residents: %
Using the concept of relative frequency, it is found that:
Republican residents of County 1: 37.9%.Democratic residents of County 1: 62.1%.Total Republican residents: 58.9%.Total Democratic residents: 41.1%.----------------------------------
A relative frequency is the number of desired outcomes divided by the number of total outcomes.
To find it as a percentage, we multiply by 100%.
----------------------------------
The table used is the image at the end.
----------------------------------
County 1 has 6,520 residents, out of which 2,470 are Republican.
2470*100%/6520 = 37.9%
Thus:
Republican residents of County 1: 37.9%.
----------------------------------
County 1 has 6,520 residents, out of which 4,050 are Democratic.
4050*100%/6520 = 62.1%
Thus:
Democratic residents of County 1: 62.1%.
----------------------------------
Total of 24,505 Residents, 10,075 Democrats and 14,430 Republicans.
10075*100%/24505 = 41.1%
14430*100%/24505 = 58.9%
Thus:
Total Republican residents: 58.9%.
Total Democratic residents: 41.1%.

The Mallards pay their two quarterbacks $7.2 million and $1.4 million. If the team salary is $33 million a year and their budget for quarterbacks is 25% of total salaries. Are they over budget? a) Yes b) No
Answer:
a) Yes
Step-by-step explanation:
The computation is shown below:
Given that
Their two quarterbacks is $7.2 million and $1.4 million
Its total is
= $7.2 million + $1.4 million
= $8.6 million
Now if the team salary is $33 million
And their budget is 25% of total salaries
i.e.
= $33 million × 25%
= $8.25 million
So as we can see that it it overbudget as the target is $8.25 million but it is $8.6 million
SO, the correct option is a.

You can paint 75 square feet of a surface every 45 minutes. Determine how long it takes you to paint a wall with the given dimensions. 8 ft $\times$ 5 ft
Answer:
24 minutes
Step-by-step explanation:
The Dimensions of the wall are given as:
8ft × 5ft = 40ft² or 40 square feet
We are told that: You can paint 75 square feet of a surface every 45 minutes.
Hence:
75 ft² = 45 minutes
40 ft² = x minutes
Cross Multiply
75 ft² × x = 40 ft² × 45 minutes
x = 40 ft² × 45 minutes/75 ft²
x = 24 minutes
Therefore, It will takes you 24 minutes to paint a wall with dimensions 8ft × 5 ft
