In degrees, what is the measure of MFE?
Answer:
30°
Step-by-step explanation:
It tells us that MFE is equal to (x + 6)° so we need to find x
The angle accross from MFE is RFT. These angles are congruent, because they are a vertical pair. So RFT is also equal to (x + 6)°
The angle RFT and PFR combined form a right angle. This means that RFT + PFR = 90°.
They told us that PFR = (3x - 4)°
so that means that (x + 6) + (3x - 4) = 90°
Knowing that we can just solve the equation by combining like terms
4x + 2 = 90
Subtract two from both sides
4x = 88
And then divide by 4
x = 22
Now we can plug in 22 in the original equation to find MFE
22 + 6 = 30
so MFE = 30°

help please I have too many points and I also need help on my math
Answer:
Complementary
x = 55
Step-by-step explanation:
Complementary angles add up to 90°, while supplementary angles add up to 180°.
In this situation, the two angles add up to 90° (the little box means that an angle is a 90° angle) So, the angles are complementary.
Now, we can write this equation.
x + x - 20 = 90
Simplify.
2x - 20 = 90
2x = 110
x = 55
Just in case, let's check the answer.
Substitute x = 55 into (x + x - 20 = 90)
55 + 55 - 20 = 90
110 - 20 = 90
90 = 90
This is true, so x = 55 is correct.
I hope this helps! Feel free to ask any questions!
Solve for X and round to the nearest hundredth
Answer:
Pretty sure it's 20.24.
Step-by-step explanation:
Since you know the side adjacent to the reference angle and you want to find the side opposite, you're going to need to use tangent, which is opp/adj.
tan(39) = [tex]\frac{x}{25}[/tex]
Find the tangent of 39...
0.8097 is the approximate value. So...
0.8097 = [tex]\frac{x}{25}[/tex]
Now, switch the sides to make it easier.
[tex]\frac{x}{25}[/tex] = 0.8097
Multiply both sides by 25.
x = 20.24
What is the equation of the coordinate A and B if they are (4,7), (6,3) respectively. What is the equation of the straight line.
Answer: y+2x=15
Step-by-step explanation:
Given
Two points A and B are (4,7) and (6,3) respectively
Using two-point form
[tex]\Rightarrow \dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Putting values
[tex]\Rightarrow \dfrac{y-7}{x-4}=\dfrac{3-7}{6-4}\\\\\Rightarrow \dfrac{y-7}{x-4}=\dfrac{-4}{2}=-2\\\\\Rightarrow y-7=-2x+8\\\\\Rightarrow y+2x=15[/tex]

The City of Killeen utilities charges for water usage per gallon on a monthly basis as listed below.
Up to 500 gallons ($0.15/gallon)
More than 500 gallons - 1000 gallons ($0.33/gallon)
How much will Mrs Lapid pay if she uses 795 gallons in a particular month?
Answer:
$262.35
Step-by-step explanation:
From the above question we are given the cost for a given range of gallons
Mrs Lapis uses 795 gallons, hence this falls into the range of:
More than 500 gallons - 1000 gallons ($0.33/gallon)
Hence:
1 gallon = $0.33
795 gallons = $x
Cross Multiply
1 gallon × $x = $0.33 × 795 gallons
$x = 795 × $0.33
x =$ 262.35
Therefore, Mrs Lapis would pay $262.35 every month
WHAT IS EQUIVALENT TO THE INEQUALITY 2X>6?
Answer:
x > 3
Step-by-step explanation:
Simply isolate the inequality to get a equivalent inequality. Treat the sign > like an equal sign, what you do to one side, you do to the other side of the inequality.
Isolate the variable, x. Divide 2 from both sides of the equation:
(2x)/2 > (6)/2
x > 6/2
x > 3
x > 3 is your equivalent inequality.

HURRYYY A company is introducing a new product. The equation y = –0.001(x – 600)2 + 90 predicts the expected profit, in thousands of dollars, where x represents the number of thousands of units of the product sold by the company. How many units must be sold to yield a maximum profit? 90 600 90,000 600,000
Answer:
d
Step-by-step explanation:
^u^
The amount of units that must be sold to a number yields a maximum profit is 600. Hence 600 units will be the correct option.
How to find maxima?To find the maxima of any function it needs to differentiate with respect to the dependent variable and equate with zero to get stationary points.
After achieving the stationary points it needs to put on the double derivative of that function to check whether it's maxima or minima.
If the double derivative got negative then it will be maxima.
Given that function
f(x) = -0.001(x-600)² + 90
By differentiation
[tex]$f'(x)$[/tex] = -0.002(x - 600) + 90
Now equate with zero
-0.002(x - 600) + 90 = 0
x - 600 = 0
x = 600
Now checking the x at double derivative
[tex]$f''(x)$[/tex] at x = 600 it is coming out to -0.002 which is negative Hence, the 600 units will be the correct answer.

Calculate the value of p and the value of q
Answer:
q= 20 p= 56
Step-by-step explanation:
A angle is also 62°
Answer:
q = 20 degrees
p = 59 degrees
Step-by-step explanation:
to find q, find all the other interior angles within that shape and subtract it from 360
angle E = 180 - 62 = 118
angle b = 90
angle c = 132
360 - (118 + 90 + 132) = 20
angle q = 20 degrees
to find p, add all the other interior angles within that shape and subtract it from 180
angle e = 62 degrees
angle a and b are the same so, take 62 and subtract it from 180 then divide the answer by 2
180 - 62 = 118
118 / 2 = 59
angle a = 59 degrees
angle p = 59 degrees

a) what is the area of a square park whose perimeter is 2000m.
b)what is the simplified form of 2² X 2⁵ (with explanation please)
Answer:
Step-by-step explanation:
Perimeter of square park = 2000 m
4*side = 2000
side = 2000 ÷ 4
side = 500 m
Area of square park = side * side
= 500 * 500
= 250000 m²
