charges customers a fee of $150 just to come to their house
and then $75 per hour that he is there. Darnel charges a fee
of $50 for a home visit, plus an additional $125 per hour. How
long do they work to earn the same amount?

Answer:
2 hoursStep-by-step explanation:
Equations for each
Johnny:
J(x) = 75x + 150Darnel:
D(x) = 125x + 50In order to get J(x) = D(x) we need to make right sides equal and solve for x:
75x + 150 = 125x + 50 125x - 75x = 150 - 50 50x = 100 x = 2what is the 6th term for 16,48,144
Answer:
Step-by-step explanation:
16, 48 , 144 ...... is a geometric sequence.
first term = a = 16
common ratio = r = 2 term ÷ first term = 48 ÷ 16 = 3
nth term = [tex]ar^{n-1}[/tex]
[tex]6th \ term = 16 * (3)^{6-1}\\\\\\= 16 * 3^{5}\\\\= 16 * 243\\\\= 3888[/tex]

a pair of jeans is only $12 after a 60% discount what is the original price
Answer:
20
Step-by-step explanation:
I did this test is 20
60 percent of 20 is 12 dollars
The original price of a pair of jeans would be; 30 dollar.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b% Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Given that a pair of jeans is only $12 after a 60% discount.
The original price in percentage terms = 100%
After the first discount, the price is : 100- 60% = 40%
The equation can be used to represent the price;
40% x original price = $12
0.40 x p = 12
where p = original price
Divide both sides of the equation by 0.40;
p= $30
Hence, The original price of a pair of jeans would be; 30 dollar.

a line has a y-intercept on -11 and a slope of .25. Write it's equation in slope intercept form
Answer:
[tex]y = \frac{1}{4} x - 11[/tex]
Step-by-step explanation:
Slope- intercept form
y= mx +c, where m is the slope and c is the y-intercept.
Slope
= 0.25
= ¼
Substitute m= ¼ into the equation:
y= ¼x +c
Given that the y-intercept is -11, c= -11.
Thus, the equation of the line is y= ¼x -11.

2y - 4x + 6 = 0
(If u don’t know DONT answer and correct answer gets BRAINLIEST
Step-by-step explanation:
2y - 4x + 6 = 0
2y = 4x - 6
y = 4x/2 - 6/2
y = 2x - 3
Answer:
[tex]y = 2x - 3[/tex]
Step-by-step explanation:
Simply make the y as the subject
[tex]2y - 4x + 6 = 0 \\ 2y - 4x = - 6 \\ 2y = - 6 + 4x \\ \frac{2y}{2} = \frac{ - 6 + 4x}{2} \\ y = - 3 + 2x \\ y = 2x - 3[/tex]
So,
[tex]y = mx + b \\ y = 2x - 3[/tex]

Which proportion can be used to find 65% of 90?
Answer:
The proportion which represents the 65% of 90 is:
Step-by-step explanation:
Given information:
We need to find the proportion that can be used to find
65% of 90
Let us take :
% of
So,
Hence , the proportion which represents the 65% of 90 is
Answer:
The proportion [tex]\frac{65}{100} = \frac{x}{90}[/tex]
Step-by-step explanation:
[tex]\frac{65}{100} = \frac{x}{90}[/tex]
(65)(90) = 100x
5850/100 = x = 58.5
58.5 = 65% of 90
Alternatively, you can use the more direct approach:
[tex]\frac{65}{100} (90)[/tex]
= [tex]\frac{65 * 9}{10}[/tex] = 585/10 = 58.5
what is the value of x?
Answer:
x = 51°
Step-by-step explanation:
The image of the triangle is an isosceles triangle. Since it is an isosceles triangle, ∠DFE = ∠FDE.
78 + x + x = 180
=> 2x = 102
=> x = 51°

The law of sines can only be applied to right triangles.
A. True
B. False
The law of sines can't only be applied to right triangles. Therefore, it's B. False.
What is the law of sines?The Law of Sines says that in any given triangle, the ratio of any side length to the sine of its opposite angle is the same for all the three sides of the triangle.
The law of sines is used to solve any triangle, when we know two angles and one side or two angles and one included side. So, it can be used on non-right triangle and right triangle as the case may be.
The sine law states that the ratio of a triangle's side length to the sine of the opposite angle is the same for all three sides. When we are given a) two angles and one side, or b) two sides and a non-included angle, we use the sine rule.

A. (-1,0)
B. (1,0)
C. (1,-1)
D. None of these choices are correct
Answer:
C
Step-by-step explanation:
To find which of the given choices are solutions for the system of equations, we need to:
-substitute x, and y with the given coordinates and
-check if they are solutions for both equations.
7x+y= 6
x+ 2y = -1
A. (x = -1, y = 0) ❌
7(-1)+0= 6; -7 =6 FALSE

Choose one logarithmic property.
Use an exponential property to defend the validity of that specific logarithmic property. Show all work.
The logarithmic property chosen here is:
[tex]log_{a}[/tex] m - [tex]log_{a}[/tex] n = [tex]log_{a}[/tex] [tex]\frac{m}{n}[/tex], and its validity is proven below:
The logarithmic properties are up to six, but one of it that is applicable here is:
[tex]log_{a}[/tex] m - [tex]log_{a}[/tex] n = [tex]log_{a}[/tex] [tex]\frac{m}{n}[/tex]
In the above expression, both the numerator and denominator have the same base number, but different powers. So in this case, dividing a number of power m by the same number but of power n would given an answer that is the same as the number to the power of the difference between m and n.
For example: Solve;
a. [tex]log_{10}[/tex] 6 - [tex]log_{10}[/tex] 3
b. [tex]log_{10}[/tex] 8 - [tex]log_{10}[/tex] 5
c. [tex]log_{b}[/tex] 6 - [tex]log_{b}[/tex] 2
Solutions:
a. [tex]log_{10}[/tex] 6 - [tex]log_{10}[/tex] 3 = [tex]log_{10}[/tex] [tex]\frac{6}{2}[/tex]
= [tex]log_{10}[/tex] 2
= 0.3010
b. [tex]log_{10}[/tex] 8 - [tex]log_{10}[/tex] 5 = [tex]log_{10}[/tex] [tex]\frac{8}{5}[/tex]
= [tex]log_{10}[/tex] 1.6
= 0.2041
c. [tex]log_{b}[/tex] 6 - [tex]log_{b}[/tex] 2 = [tex]log_{b}[/tex] [tex]\frac{6}{2}[/tex]
= [tex]log_{b}[/tex] 3

A balloon with a 50 ft string makes an angle of 39 degrees with the ground. How high above the ground is the balloon if the land of the person holding the balloon is 5 ft above the ground?
Answer:
Step-by-step explanation:
This is late but the other is not an answer at all.
The 50 ft string makes an angle of 39 degrees with the ground so the stromg and balloon form a right-angle triangle to the ground.
The height of balloon from string = 50*sin(39degrees)
= 31.47 ft
As the string is held by a person 5 ft above ground, the balloon is above ground at 31.47 + 5
= 36.47 ft.

Find the values of a and b that make each equation true.
1) 3 – 36i = 9a + 4bi
2) a – 15i = -7 – (2b-3)i
Step-by-step explanation:
1) 3 – 36i = 9a + 4bi
3 = 9a => a = 3/9 = ⅓
-36 = 4b => b = -36/4 = -9
2) a – 15i = -7 – (2b-3)i
a = -7
-15 = -(2b-3)
2b-3 = 15
2b = 18
b = 18/2= 9
