the situation.
An electrician charges $75 for a service call and $25 for each hour they are on the job. If the electrician spends x hours at a house, what will the total charge, C(x) be?
Answer:
x=number of hours
c(x)= 25x+75
y-intercept= (0, 75)
Equation= y=25x+75
Slope= 25
Step-by-step explanation:
75 would be the y intercept(constant) because that's the initial charge for a call.
25 would be the coefficient for x because the hour you spend on the call varies.
The slope is how steep the line is, in this case it is 25.
x is the number of hours because that is the time that varies.

Find the lateral surface area of a cylinder with a diameter of 21 inches and a height of 15 inches.
Answer:
989.6inches^2
Step-by-step explanation:
A) Radius = You half the diameter so... 21/2
Radius = 10.5
Height = 15
A = 2 x pi x d/2 x h
B) 2 x pi x 21/2 x 15
A = 989.6inches^2

A rectangle has vertices at P (16,16), Q(16,-16), R(-16,-16) and S(-16,16). The origin is the center of dilation and the rule of a dilation is (x,y)→(1/4x, 1/4y) What is P' of the dilated image, PQ’R’S’?
Answer:
(4, 4)
Step-by-step explanation:
So you're trying to find what P' is, and P' would be the dilation of P. This means that you apply the rule (x, y) --> (1/4x, 1/4y) with the coordinate point (16, 16). This would be:
(16, 16) --> (1/4 * 16, 1/4 * 16) = (4, 4)

Answer:
[tex]\theta \approx 1.23^\circ[/tex]
Step-by-step explanation:
The expression has been given as:
[tex]tan(\theta) = \frac{50}{18}[/tex]
Required: Find [tex]\theta[/tex]
Simplify the fraction
[tex]tan(\theta) = 2.7778[/tex]
Take arc tan of both sides
[tex]\theta = tan^{-1}(2.7778)[/tex]
[tex]\theta \approx 1.23^\circ[/tex]

Answer:
-4.24264 -4.24264i
Step-by-step explanation:
Evaluate the sine and cosine terms and multiply.
6(cos(225°) +i·sin(225°)) = 6(-√2/2 -i·√2/2)
= -3√2 -i·3√2 ≈ -4.24264 -4.24264i

Step-by-step explanation:
Given
The attached triangle
Required
Number of square feet materials needed
This simply means that we calculate area;
[tex]Area = 0.5 * base * height[/tex]
[tex]Area = 0.5 * (14ft\ 2in) * (8ft\ 6in)[/tex]
Convert to ft [divide by 12]
[tex]Area = 0.5 * (14+ 2/12) * (8+ 6/12)[/tex]
[tex]Area = 0.5 * (14.17) * (8.5)[/tex]
[tex]Area = 60.23ft^2[/tex]
(B) is correct

Answer:
245 ft sq
Step-by-step explanation:
Find the are of the triangle and the square seperatly.
Area of a square is A = s * s
A = 14 * 14 = 196 ft sq
Focusing on the triangle, the dotted line is the same length as the bottom of the square. 14 ft
Area of a triangle is A = 1/2 * b * h
A = 1/2 * 14 * 7
A = 7 * 7
A = 49 ft sq
So, 196 + 49 = 245

Sasha is the manager at a factory.
Last weekend 15 employees assembled 390 identical wardrobes.
Sasha wants 1200 of these wardrobes to be assembled next weekend.
How many employees does Sasha need next weekend?
You must show your working.
The number of employees Sasha would need next weekend are = 46
Calculation of total employeesFor a weekend, 15 employees = 390 wardrobes
The number of wardrobes to be assembled next weekend= 1200
If 390 wardrobes = 15 employees
1200 wardrobes = X employees
Make x the subject of formula,
X = 1200 × 15/390
X = 18000/390
X = 46
Therefore, the number of employees Sasha would need next weekend are = 46

Step-by-step explanation:
a Carver begins work on the following block of granite that weighs 2700g what is the density of the granite
Density" of the given granite block is 2.7g/cm
3
.
Explanation:
Density of an object is defined as the mass occupied per unit volume. “Density” is represented by “ρ”. Mathematically, \rho=\frac{m}{v}ρ=
v
m
where, “m" mass of an object and "v" is volume of an object.
Given that,
Dimensions of the block are 20 cm, 5 cm and 10 cm.
\text { Volume of the block is } l \times b \times h Volume of the block is l×b×h
\text { Volume of the block is } 20 \times 5 \times 10 Volume of the block is 20×5×10
\text { Volume of the block is } 1000 \mathrm{cm}^{3} \text { . } Volume of the block is 1000cm
3
.
Mass of the block is 2700 g.
Substitute the given values in \rho=\frac{m}{v}ρ=
v
m
to find density of a block.
\rho=\frac{2700}{1000}ρ=
1000
2700
\rho=2.7 \mathrm{g} / \mathrm{cm}^{3}ρ=2.7g/cm
3
\text { "Density" of the given granite block is } 2.7 \mathrm{g} / \mathrm{cm}^{3} "Density" of the given granite block is 2.7g/cm
