Describe two different ways you could find measure of CFD. What is the measure of
this angle?
Answers
Answer:
∠CFD = 60°
Step-by-step explanation:
Along line CE:
∠AFE + ∠AFB + ∠BFC = 180° (sum of angles on a straight line)
(7x + 4) + (8x + 6) + (6x + 2) = 180
collecting alike terms:
7x + 8x + 6x + 4 + 6 + 2 = 180
21x + 12 = 180
21x = 168
x = 8°
We could find the measure of CFD using:
a) Along line AD:
∠AFB + ∠BFC + ∠CFD = 180° (sum of angles on a straight line).
(8x + 6) + (6x + 2) + ∠CFD = 180
14x + 8 + ∠CFD = 180
∠CFD = `180 - (14x + 8)
∠CFD = 172 - 14x
b) ∠CFD = ∠AFE (vertical opposite angles are equal)
∠CFD = 7x + 4
To find value of ∠CFD, substitute x = 8
∠CFD = 7(8) + 4
∠CFD = 60°

The deductions from Jennifer Miller's monthly pay are federal income tax (FIT) of $87, state income tax (SIT) of 2.5% of gross, (CIT) city income tax of 1.2% of gross, social security, and medicare. Her next monthly pay is $3,981.22. Find Jennifer's monthly gross pay.
A) $4,529.05
B) $4,551.23
C) $4,576.58
D) $4,589.08
Answers
Answer:
$4,711.31
Step-by-step explanation:
Calculation for Jennifer's monthly gross pay
First step is to calculate The total tax percentage deductions
Using this formula
Total tax percentage deductions =State tax + City tax + Social security + Medicare
Let plug in the formula
Total tax percentage deductions = 3.5% +2.5% +6.2% +1.45%
Total tax percentage deductions = 13.65%
Now let calculate the monthly gross pay
Monthly gross pay= ($3,981.22 +87)/(1-13.65%)
Monthly gross pay= ($3,981.22 +87)/0.8635
Monthly gross pay=$4,068.22/0.8635
Monthly gross pay= $4,711.31

Answer:
A. if table is extendedD. if only the values in the table considered.Step-by-step explanation:
We can see on the graph of g(x) that y-intercept is (0, 2)
The table doesn't have the value for x = 0 but we can observe that it is exponential function and has the formula:
f(x) = 3^xWe can find its y-intercept:
f(0) = 3^0 = 1We can compare and see that:
f(0) = 1 < g(0) = 2So the function g(x) has a greater y-intercept. This is option A.
====
Note: If only the values in the table considered, then correct option is D.

1. 20 squared+ 21 squared = 841
Answer to number 1
2)Same for this. 4^2+5^2= 9^2
3)a^2+b^2 = ab^2 because since a and b are different letters/variables you cannot combine them therefore it is just ab.
4) (-1)^2 = 1 because -1 multiply by -1 again you would get positive 1. Next you do 1+0^2 = 1. Because 0^2 is just 0 because 0times 0 =0 so 1+0 = 1

Each of three friends—Lin, Jada, and Andre—had the goal of raising $40. How much money did each person raise?
Lin raised 100% of her goal.
Jada raised 50% of her goal.
Andre raised 150% of his goal.
Answers
Answer:
Down Below
Step-by-step explanation:
Lin: 100% of 40 = $40
Jada: 50% of 40 = $20
Andre: 150% of 40 = $60
The money raised by three friends is given below,
Lin raised 100% of her goal = $40
Jada raised 50% of her goal = $20
Andre raised 150% of his goal = $60
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Each of the three friends—Lin, Jada, and Andre—had the goal of raising $40.
The amount raised by all three friends will be calculated as,
Lin: 100% of 40 =40 x 1 = $40
Jada: 50% of 40 = 40 x 0.5 = $20
Andre: 150% of 40 =40 x 1.5 = $60
Therefore, Lin raised 100% of her goal which is $40 Jada raised 50% of her goal which is $20 and Andre raised 150% of his goal which is $60.

Identify the zeros of each function. y=(x-7)^2

Answer:
x = 7 (multiplicity 2)
Step-by-step explanation:
When the function is written in factored form, the zeros are the values of the variable that make the factors zero.
y = (x -7)(x -7)
The values x = 7 and x = 7 will make the factors zero. The zero is said to be x=7 with multiplicity 2.
__
On the graph, the zeros are the x-intercepts (where y=0). The graph only touches the x-axis, but does not cross. With some experience, you can recognize that this is a zero with even multiplicity (2).

Answer:
cosC = 30/50
Step-by-step explanation:
Before you find cosC, you should know that:
tangent = opposite side/adjacent side
sine = opposite side/hypotenuse
cosine = adjacent side/hypotenuse
You should also know that trigonometric ratios work for only right triangles.
If cosine = adjacent side/hypotenuse, then:
cosC = 30/50
cosC = 0.6
If rounding to the nearest four decimals, it should be 0.6000.

On the playground, 1/4 of the students are on the jungle gym, and 1/3 f the students are playing kickball. What part of all the students on the playground is on the jungle gym or playing kickball?
Answers
Answer:
7/12 of the students
Step-by-step explanation:
So first you would need to get your fractions to have the same denominator. When your trying to get your fractions to get the same denominato. You must multiply both the numerator and denominator.
The most common denominator from 1/4 and 1/3 is 12. So you multiply both the numerator and denominator of 1/4 by 3. So then your new fraction is 3/12. Now you multiply 1/3, both numerator and your denominator by 4. Then your new fraction is 4/12. So The last step is to add both of your numerators. Never add the denominators together. And at last you have your answer. 7/12.
