wo mechanics worked on a car. The first mechanic charged $95 per hour, and the second mechanic charged $75per hour. The mechanics worked for a combined total of 20 hours, and together they charged a total of $1800. How long did each mechanic work?
Answer:
he first one worked 15 hours, the second one worked 5 hours.
Step-by-step explanation:
First mechanic worked x hours, then second one worked 20 - x hours
First one charged $95*x, second one charged $75*(20-x)
Total charge = 95x + 75(20 - x) = 1800
95x + 1500 - 75x = 1800
20x = 300
x = 15, 20 - x = 5
So the first one worked 15 hours, the second one worked 5 hours.

A triangle has vertices at R(1, 1), S(–2, –4), and T(–3, –3). The triangle is transformed according to the rule R0, 270°. What are the coordinates of S'?
(–4, 2)
(–2, 4)
(2, 4)
(4, –2)
Answer:
(-4,2)
Step-by-step explanation:
Knowing that/Given that:
The vertices of the triangle are rotated about the origin by 270° counter-clockwise.
In Addition, This transformation changes the co-ordinate (x,y) to (y,-x).
Before (x,y) After ( y, - x)
Vertices New vertices after 270° rotation
R= (1,1) R' = (1,-1)
S= (-2,-4) S' = (-4,2)
T= (-3,-3) T' = (-3,3)
Hence, the answer is (-4,2)

what are complex numbers ??? please gyus itz urgent .....!
Explanation:
Complex numbers are numbers that have both imaginary and real number parts. Imaginary numbers occur when you take the square root of negative numbers. Here are some examples of imaginary numbers:
[tex]\sqrt{-1} = i[/tex] and [tex]\sqrt{-16} = 4i[/tex]
Real numbers are just normal numbers.
Complex numbers can be expressed generally in the form:

In 2017, it was estimated that the average amount spent on winter holiday gifts in the United States was $906. Based on the estimate from the Waldfogel study, how much of this would be deadweight loss
Based on the estimate from the Waldfogel study, 10[tex]\%[/tex] of this would be a deadweight loss, i.e., [tex]\[/tex]90.6 would be the deadweight loss.
Deadweight loss means the economic inefficiency that takes place when the allotment of resources in a market isn't at the optimal position.
The study suggested that the average recipient's valuation of the gift received was approximately 90[tex]\%[/tex] of the actual purchase price of the gift.
This means that 10[tex]\%[/tex] of the value of the gift gets lost in between.
This loss of 10[tex]\%[/tex] in value constitutes the deadweight loss.
The average amount spent on gifts = $906
Percentage loss in value = 10[tex]\%[/tex] or 0.10
Calculation of the deadweight loss,
DWL = Average amount spent on gifts × Percentage loss in value
DWL = [tex]\[/tex]906 × 0.10
Thus, the deadweight loss would be [tex]\[/tex]90.6.

The total distance an ant crawls varies directly with the time in seconds. The ant crawls a total distance of 160 centimeters in 20 seconds.
What is the time in seconds the ant crawls when the total distance is 216 centimeters?
8 s
11 s
25 s
27 s
Answer:
27sStep-by-step explanation:
Given data
total distance=160 cm
time taken =20seconds
We know that speed =distance/time
So let us solve for the speed of the ant
speed=160/20
speed= 8cm/s
Also when the distance is 216,and the ant uses the same speed,it will take the ant
time=distance/speed
time=216/8
time= 27seconds

Find the length of cable 1 in the diagram below
Answer:
cable 1 ≈ 54.63 ft
Step-by-step explanation:
using Pythagoras' identity in the right triangle having cable 1 as its hypotenuse.
let cable 1 be x , then
x² = 22² + 50² = 484 + 2500 = 2984 ( take square root of both sides )
x = [tex]\sqrt{2984}[/tex] ≈ 54.63 ft ( to 2 dec. places )

Liner or non linear and why
If a function is non-linear, there must be an exponent in the equation. For example, [tex]x^{2}[/tex] or [tex]x^{3}[/tex].
Since this function has no exponent attached to the x-variable, we can assume this function is linear.

[tex]\int{[sin(9x)cos(9x)]} \, dx[/tex]
Recall the double angle identity,
sin(2x) = 2 sin(x) cos(x)
Then we can write
sin(9x) cos(9x) = 1/2 sin(2 • 9x) = 1/2 sin(18x)
Then
∫ sin(9x) cos(9x) dx
= 1/2 ∫ sin(18x) dx
= -1/2 • 1/18 cos(18x) + C
= -1/36 cos(18x) + C
though you could continue with another double angle identity,
cos(2x) = cos²(x) - sin²(x)
to rewrite the antiderivative as
= -1/36 (cos²(9x) - sin²(9x)) + C
= 1/36 (sin²(9x) - cos²(9x)) + C
