Find m CF
44
D
5
-52
Answer:
Step-by-step explanation:
Answer:
148°
Step-by-step explanation:
The external angle at E is half the difference of the measures of arcs FD and FC.
(CF -44°)/2 = 52°
CF -44° = 104° . . . . multiply by 2
CF = 148° . . . . . . . . add 44°
The measure of arc CF is 148°.
Pls answer this I need it
Answer:
f = 42 , q = 127
Step-by-step explanation:
3f + 1 and 127 are alternate angles and are congruent , so
3f + 1 = 127 ( subtract 1 from both sides )
3f = 126 ( divide both sides by 3 )
f = 42
q and 127 are corresponding angles and are congruent , so
q = 127

When a figure rotates around a point, this point is called the
Answer:
A image
B. origin
C. graph
D. center of rotation
Answer:
Your answer is D. center of rotation!
Step-by-step explanation:
A rotation is a transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point. The fixed point is called the center of rotation . The amount of rotation is called the angle of rotation and it is measured in degrees.
How much paneling needs to be removed?
I'll draw it for you cause im nice. (Blue bit is the part we dont have paneling on).
So the the total surface area of panelling needed to remove will be (8 x 6 1/2) x 2 = 104. And also 3 x 8 x 2 = 48. So total surface area = 152. So its 152ft^2

approximate the square root of 110
Answer:
10.4880885 or 10.5
Step-by-step explanation:
The square root of 110 is a decimal ... 10.4880885
If we round up it will be 10.5
Answer:
10.488 to nearest thousandths
Step-by-step explanation:
If you mean using a calculator, sqrt(110) is approximately 10.488.
If you mean by hand (unlikely), there are methods such as Newton-Raphson method that converge quite quickly (after around 10 iterations it's basically no different than your calculator)
X+4,x+12,x-1 and x+5 are in proportion.find the value of x
Answer:
Step-by-step explanation:
As they are in proportion,
x +4 : x +12 :: x -1 : x + 5
Product of means = Product of extremes
(x + 12)(x -1) = (x +4)(x+5)
Use FOIL method for polynomial multiplication
x*x + x*(-1) + 12*x + 12*(-1) = x*x + x*5 + 4*x + 4*5
x² - x + 12x - 12 = x² + 5x + 4x + 20
Combine like terms
x² + 11x - 12 = x² + 9x + 20
x² + 11x - 12 - x² - 9x - 20 = 0
Combine like terms
x² - x² + 11x -9x -12 -20 = 0
2x - 32 = 0
2x = 32
x = 32/2
x = 16

What is the equation of the line?
Answer: 5x + 4y - 6 = 0
Step-by-step explanation:
Find the slope of the line by finding 2 points that are on the line
(-2,4) and (2,-1)
(4--1)/(-2-2) = 5/-4
y = -5x/4 + c
Substitute (2,-1)
-1 = -10/4 + c
6/4 = c
So the equation is y = (6-5x)/4
4y = 6-5x
5x + 4y - 6 = 0
(Side note: So many people are asking about line equations)

Solve the system of linear equations BY ELIMINATION. Show a step-by-step process.
3x - 2y = -2
5x - 3y = -4

[tex]\\ \tt\hookrightarrow 15x-9y=-12--(4)[/tex]
Subtracting
[tex]\\ \tt\hookrightarrow -y=+2[/tex]
[tex]\\ \tt\hookrightarrow y=-2[/tex]
Put in eq(1)
[tex]\\ \tt\hookrightarrow 3x+4=-2[/tex]
[tex]\\ \tt\hookrightarrow x=-2[/tex]
Answer:
x = -2 and y = -2
Explanation:
Given equations:
3x - 2y = -2
5x - 3y = -4
---------------------
Make the value before y equal:
( 3x - 2y = -2 ) * 3
9x - 6y = -6 .........equation 1
( 5x - 3y = -4 ) * 2
10x - 6y = -8 ...........equation 2
solve them by elimination:
10x - 6y = -8
-9x + 6y = +6
----------------------
x = -2
If x is -2
Then y:
10x - 6y = -8 .................from equation 2
-6y = -8-10x
y = [-8 - 10(-2)]/-6
y = -2
Members of a lacrosse team raised $1793.50 to go to a tournament. They rented a bus for $757.50 and budgeted $64.75 per player for meals. Write and solve an equation which can be used to determine
x
x, the number of players the team can bring to the tournament.
Answer:
They can bring 16 students to the tournament
Step-by-step explanation:
$1793.50 - $757.50 = 1063
$1063 / $64.75 = 16
Answer:
16 students
Step-by-step explanation:
Hello :)
This question gave us a flat charge of 757.50 dollars for the bus, which means it does not depend how many members of the lacrosse team ride the bus.
However, the meals cost 64.75 per member.
So to make an equation, the bus charge would be the y-intercept (If no member went, they still paid for the bus fee) and the meals would be the slope (since it is dependent on how many members ride the bus.)
The total would add up to be 1783.50, so the equation would be:
1793.50=64.75x+757.50 where x=the number of players the team can bring to the tournament without going outside of their budget
Let's solve now.
1793.50=64.75x+757.50
-757.50 -757.50
1036=64.75x
x=16

#CARRYONLEARNING
NEED HELP ASAP DUE SOON!!!!
Answer:
Step-by-step explanation:
We can easily get 'a' in the equation by setting x to zero which will get rid of the b variable leaving us with:
a = 2
Now for b, we know the second point is (1,6), so let's plug it into the function
6 = 2 * b^1
b = 3
Thus the function is [tex]y = 2*3^{x}[/tex]
Hope that helps!
