Answer:
measure of <DFH=56
Step-by-step explanation:
The two triangles are similar, so their angles are the same, but their lengths are different.
If their angles are the same, then 98-6x=63-x.
98-6x=63-x (subtract: 98-63)
35-6x=-x (add 6x-x)
35=5x (divide by 5)
7=x (Then make sure you answer the question and put x in 63-x.)
63-(7)=56

Select all equations that have at least one integer solution.
Answers
Answer:
b and d
Step-by-step explanation:
The equations have at least one integer solution are equation B: √(3x) = 75 and equation D:√x = x - 12.
What is the solution to the given equations?The value of x is known as the solution.
A. √(4x) = 5
On squaring, we have
4x = 25
x = 6.25
The value is not an integer.
B. √(3x) = 75
On squaring, we have
3x = 5625
x = 1875
The value is an integer.
C. 8√x = √16
On squaring, we have
64x = 16
x = 0.25
The value is not an integer.
D. √x = x - 12
On squaring, we have
(x - 12)² = x
x² - 24x + 144 = x
x² - 25x + 144 = 0
(x - 16)(x - 9) = 0
x = 9, 16
The value is an integer.
E. √(10 - x) = x - 2
On squaring, we have
(x - 2)² = 10 - x
x² - 4x + 4 = 10 - x
x² - 3x - 6 = 0
(x - 4.37)(x + 1.37) = 0
x = -1.37, 4.37
The value is not an integer.

Answers
Answer: $270
Step-by-step explanation:
1. calculate how much he's getting paid per hour
- 360 / 12 = $30
2. calculate how much he's getting paid for 9 hours
- 30 * 9 = $270
The amount he would be paid for 9 hours of work is 270.
How much would the painter be paid for 9 hours of work?The first step is to determin1 be how much the painter would be paid for 1 hour of work.
Pay for working for 1 hour = 360 / 12 = 30
The pay for 9 hours = 30 x 9 = 270

For f(x) = 5x – 3 and g(x) = 2x2 - 5, find the following functions.
a. (fog)(x); b. (gof)(x); c. (fog)(2); d. (gof)(2)
Answers
Answer:
See answer below
Step-by-step explanation:
Given the functions f(x) = 5x – 3 and g(x) = 2x2 - 5, find the following functions.
a)(fog)(x) = f(g(x))
f(g(x)) = f(2x^2-5)
f(g(x)) = 5(2x^2-5) - 3
f(g(x)) = 10x²-25-3
f(g(x)) = 10x² - 28
b) g(f(x)) = g(5x-3)
g(f(x)) = 2(5x-3)²-5
g(f(x)) = 2(25x²-30x+9)-5
g(f(x)) = 50x²-60x+18-5
g(f(x)) = 50x²-60x+13
c)(fog)(2) = f(g(2))
f(g(x)) = f(2x^2-5)
f(g(2)) = 10(2)² - 28
f(g(2)) = 10(4)-28
f(g(2)) = 12
d) g(f(x)) = g(5x-3)
g(f(x)) = 2(5x-3)²-5
g(f(x)) = 50x²-60x+13
g(f(2)) = 50(2)²-60(2)+13
g(f(2)) = 200-120+12
g(f(2)) =80+12
g(f(2)) = 92

Given:
A figure of a circle. [tex]KJ=6,KL=x-2,ML=4[/tex].
To find:
The length of KJ.
Solution:
From the given figure it is clear that the number 6 is marked between K and J it means the number 6 represents the distance between the points K and j.
Therefore, the length of KJ is 6 units.
Note: In the given question we need to find KL instead of KJ because KJ is already given.
According to the tangent secant theorem:
[tex]a^2=bc[/tex]
Where,
a is the length of the tangent.b is the length of the external segment of the secant.c is the measure of the secant.Using the tangent secant theorem, we get
[tex]ML^2=KL\times JL[/tex]
[tex](4)^2=(x-2)\times (6+x-2)[/tex]
[tex]16=(x-2)\times (4+x)[/tex]
[tex]16=4x+x^2-8-2x[/tex]
On further simplification, we get
[tex]16=x^2+2x-8[/tex]
[tex]0=x^2+2x-8-16[/tex]
[tex]0=x^2+2x-24[/tex]
Splitting the middle term, we get
[tex]x^2+6x-4x-24=0[/tex]
[tex]x(x+6)-4(x+6)=0[/tex]
[tex](x+6)(x-4)=0[/tex]
[tex]x=-6,4[/tex]
For [tex]x=-6[/tex],
[tex]KJ=-6-2[/tex]
[tex]KJ=-8[/tex], which is not possible because side cannot be negative.
For [tex]x=4[/tex],
[tex]KJ=4-2[/tex]
[tex]KJ=2[/tex]
Therefore, the measure of KL is 2 units.

During a sale of computers, one-fourth of
the inventory was sold the first day. The next
day two-thirds of the remaining inventory was
sold. What percent of the total inventory was
sold during the second day?
Answers
Answer:
On the second day, 50% of the total computer inventory was sold.
Step-by-step explanation:
Since during a sale of computers, one-fourth of the inventory was sold the first day, while the next day two-thirds of the remaining inventory was sold, to determine what percent of the total inventory was sold during the second day, we must perform the following calculations:
1/4 = 0.25 = 25%
Remaining = 100 - 25 = 75%
75/3 = 25 x 2 = 50
Thus, on the second day, 50% of the total computer inventory was sold.

Part B
How many total miles would Ted jog if he continued to jog the same number of miles each day for 6 days? Enter your answer in the box
Answers
Answer:
Part A: 2.8 miles
Part B: 16.8 miles
Step-by-step explanation:
First, solve for how many miles Ted jogged in 1 day:
Variable x = number of miles
11.2/4 = x/1
Cross multiply
11.2 × 1 = 4 × x
11.2 = 4x
Divide both sides by 4
2.8 = x
He jogged 2.8 miles every day.
To find how many miles Ted would jog in 6 days, simply multiply his miles per day by the number of days he will jog:
2.8 miles × 6 days = 16.8 miles in 6 days
