Answer:
Trevor must score a 73.
Set UpWe will create an equation that has four values (three knowns, one unknown) that will divide by 4 to find the average.
Our equation will look like this:
[tex]\displaystyle \frac{86+83+78+x}{4}=80[/tex]
SolveFirst, combine all like terms.
[tex]\displaystyle \frac{247+x}{4}=80[/tex]
Then, divide the fraction.
[tex]\displaystyle \frac{247}{4} + \frac{x}{4} = 80[/tex]
Subtract 247/4 from both sides of the equation.
[tex]\displaystyle \frac{247}{4} - \frac{247}{4} + \frac{x}{4} = 80 - \frac{247}{4}[/tex]
[tex]\displaystyle \frac{x}{4} = \frac{73}{4}[/tex]
Then, multiply both sides of the equation by 4 to get rid of the denominator and isolate the variable.
[tex]4\times\displaystyle \frac{x}{4} = 4\times\frac{73}{4}[/tex]
[tex]x=73[/tex]
Final Answer[tex]\boxed{\bold{x=73}}[/tex]

What is the measure of angle A? HELP QUICK I WILL GIVE BRAINLIEST ANSWER!
Answer:
118
Step-by-step explanation:
you can look at the 62° it is straight line to (2y).
And the left angle of 62°, let it be 'x' . Can be measured by [ x + 62° = 180°]
[x = 180° - 62° ]
( x = 118° )
Then, A is the alternate angle of x . so, the value of A is 118.. The reason is being alternate angle.
Which equation would be used to find the cost C of a ticket after L losses? PLS HELPP
Answer:
Choice C
Step-by-step explanation:
If L represents the number of losses, and each loss decreases the total ticket price ($47.48) by $0.29, then the equation can be written as the following
47.48 - 0.29L
If you plug in any value, larger than 0, you will see that the price decreases by a constant rate of $0.29
Hope this helps!!
Answer:
47.48/0.29=163.7241379
Which trigonometric functions are undefined when x = 0?
The trigonometric functions that are undefined when x = 0:
cot(x) and cosec(x)
We need to write the trigonometric functions are undefined when x = 0.
We know that the trigonometric functions are : sine, cosine, tangent, cotangent, secant and cosecant.
For angle x the trigonometric functions would be,
sin(x), cos(x), tan(x), cot(x), sec(x), cosec(x)
We know that, when x = 0,
sin(0) = 0 and cos(0) = 1
tan(x) = sin(x) / cos(x)
So, tan(0) = 0
cot(x) = cos(x)/sin(x)
cot(0) = 1 / 0
cot(0) = undefined
Also, sec(x) = 1/cos(x)
so, sec(0) = 1
And cosec(x) = 1/sin(x)
so, cosec(0) = 1/sin(0)
cosec(0) = 1 / 0
i.e., cosec(0) = undefined
Therefore, the trigonometric functions that are undefined when x = 0:
cot(x) and cosec(x)

Answer:
Infinitely many solutions.
Step-by-step explanation:
x-2(x-6)= -x+12
x - 2x + 12 = -x + 12
x - 2x + x = 12 - 12
0 = 0.

A diver jumps from a cliff that is 48.5 feet above the surface of the water. She stops descending 12.5 feet under the water. What was the total distance of her jump?
Answer:
61 ft
Step-by-step explanation:
I'm assuming that the diver simply walked off the cliff since we were not given any information about the jump itself.
If the distance between the cliff and the surface of the water is 48.5 feet, and if the distance between the surface of the water and the place where the diver stopped descending is 12.5 feet, you would add those two distances up.
48.5 ft + 12.5 ft = 61 ft
The total distance of her jump from her was 61 feet.
Given that a diver jumps from a cliff that is 48.5 feet above the surface of the water, and she stops descending 12.5 feet under the water, to determine what was the total distance of her jump, the following calculation must be performed:
The height of the cliff and the depth at which it reached under the water must be added.
48.5 + 12.5 = X 61 = X
Therefore, the total distance of her jump from her was 61 feet.

xz Is the prependicualr disector of segment WY. WY=66. Solve for k. Enter a number only.
Answer:
k = 4
Step-by-step explanation:
A perpendicular bisector is defined as a line or a line segment that divides a given line segment into two parts of equal measurement.
So WX = XY or WX = 1/2 WY
using WX = 7k + 5 and WY = 66
7k + 5 = 66/2
7k = 33 - 5
7k = 28
k = 4

Cost of 40 pounds of apples at David's apple is $50.
Cost of 40 pounds of apples at Pam's orchards is $37.5.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Anna want to pick 40 pounds of apples,
Now, At David's apple orchard cost of first 10 pounds = $2 per pound
And, Each additional pounds $1 per pound.
So, Cost of 40 pounds of apples at David's apple is calculated as;
Cost of first 10 pounds = 10 * 2 = $20
And, Cost of 30 pounds of additional apples = 30 * 1 = $30
Hence, Cost of 40 pounds of apples at David's apple = $20 + $30
= $50
At Pam's orchards first cost of first 10 pounds = $1.50
And, Each additional pounds $0.75 per pound.
So, Cost of 40 pounds of apples at Pam's orchards is calculated as;
Cost of first 10 pounds = 10 * 1.50 = $15
And, Cost of 30 pounds of additional apples = 30 * 0.75 = $22.5
Hence, Cost of 40 pounds of apples at Pam's orchards = $15 + $22.5
= $37.5
Therefore,
Cost of 40 pounds of apples at David's apple is $50.
Cost of 40 pounds of apples at Pam's orchards is $37.5.

Answer:
The interior angles of any triangle equal 180. Triangle CDF is an equilateral triangle meaning all of its angles are the same. 180/3=60
Each angle of triangle CDF is 60
1.m<CDF=60
____________________________________________________________
Isosceles triangles have the 2 base angles the same value while the other angle is another value. IN that instance, the m<a = m<f and the m<a + m<f + m<b=180°
If we find one of the angles of ABF then we can find all of them.
the m<AFB + 35° + m<CFD + m<DFE=180°
we know that the m<CFD is 60
35+60+m<AFB + m<DFE=180
95+m<AFB + m<DFE=180
LEts look at the angle AFD
AFD is 150° and since m<AFD and the m<DFE are supplementary, the angle of DFE is 30
lets test it:
if m<DFE is 30 then
95+m<AFB + 30=180
125+m<AFB=180
m<AFB=55
therefore the m<BAF would also be 55 and the m<ABF would be 70
m<ABF=70
This is because the interior angles of any triangle add up to 180°

Give your answers to 2 decimal places.
Answer:
x= 1.13 or x= -1.45
Step-by-step explanation:
use the quadratic square root formula (-b±√(b²-4ac))/(2a) .
a= 3
b=1
c= -5
replace the variables with the numbers listed above and just work out.
x= 1.13 or x= -1.45
Answer:
x = -1/6 + 1/6√61 or x = -1/6 + -1/6 √61
Step-by-step explanation:
3x^2+x-5=0
Using quadratic formula a=3, b=1, c=-5
x = -b ± √b^2 - 4ac / 2a
x = -(1) ± √(1)^2 - 4(3)(-5) / 2(3)
x = -1 ± √61 / 6
x = -1/6 + 1/6√61 or x = -1/6 + -1/6 √61

Step-by-step explanation:
If its a right angle it is 90 degrees
Answer:
x=16
y=27.7
Step-by-step explanation:
In a 30-60 right triangle the side opposite the 30 degree angle is half the length of the hypotenuse.
x is the side opposite the 30 degree
so x=32/2=16
let's use pythagorean theorem to find y
x^2+y^2=32^2
y^2=32^2-x^2
y^2=1024-16^2
y^2=1024-256
y^2=768
y=√768
y=27.7

The illustration below is an example of a semi-regular tessellation.
A. True
B. False
The illustration below is a semi-regular tessellation is a false statement.
What is Tessellation?Tessellation is defined as the process of covering of a surface or a plane using the geometric shapes.
One geometric shape will not overlap with the other and there will not be any gaps in between.
There are regular tessellations as well as semi-regular tessellations.
Regular tessellations are the tessellations which are made using only a single type of the polygon to cover the entire surface.
Whereas in semi-regular tessellations, two or more regular polygons are used such that each vertex is the same to cover the surface.
Here, the illustration contains only one type of polygon which are tiled to each other with out any gaps.
It is actually regular tessellation.
Hence the statement that the illustration is semi-regular tessellation is incorrect.

25 families live in the squares of a 5 × 5 chessboard, each occupying a square. As it often happens, each family thinks that their neighbors (i.e. those families living in the squares with which their square shares a side) have better living units. At a town hall meeting it is resolved to make everyone happier by moving the 25 families around so that each ends up in a square of one of their former neighbors. Unfortunately try as they might, the families cannot figure out any relocation scheme to carry out this resolution. Give a very simple reason explaining why they were doomed to fail. (Hint: 25 is odd).

Find all solutions to the equation $x^2 - 8x = -16$.
Answer:
x = 4
Step-by-step explanation:
x^2 - 8x = -16
Add 16 to both sides.
x^2 8x + 16 = 0
This may be the square of a binomial.
x^2 is the square of x
16 is the square of 4 and -4.
Let's check the middle term:
2ab = 2(x)(-4) = -8x
Yes, it is the square of a binomial.
x^2 - 8x + 16 = 0
(x - 4)^2 = 0
x - 4 = 0 or x - 4 = 0
x = 4 or x = 4
Answer: x = 4
