The cost of labor for servicing cars at B&B Automotive is $50 for each whole hour or for any fraction of an hour. There is a $25 additional charge to get the oil changed & fluid checked. What would be the cost of servicing a car that required 3.45 hours of labor if the owner requested that the oil be changed and the fluids be checked? a. $100 c. $225 b. $175 d. $250
Answer:
d. $250Step-by-step explanation:
We can use the equation of a straight line to model the cost of servicing the car.
let the cost be y and the number of hours be x
and the charge per hour is m
y=mx+c
y=50x+25
given that the time is 3.45 hours it is assumed that the charge is for 4 hours since for a fraction of 0.45 hours we are charged $50
y=50(4)+25
y=200+25
y=$225
Help please! Thank you!
Answer:
The answer would be x = 20. First, you must set up a proportion, since you know that the two polygons are similar: 12/48 • 5/x. Then, you have to do cross multiplication which would result in 12x = 240. Afterwards, you must divide both sides by 12, giving you x = 20.
Which is equivalent to represent by the table
A dessert has both fruit and yogurt inside.
Altogether, the mass of the dessert is 185g.
The ratio of the mass is 2:3.
What is the mass of the yoghurt?
Answer:
74g:148g
Step-by-step explanation:
If the yogurt portion is 3, then your answer is 148g.
You have a total of 5 portions (2+3=5). Since all portions must be equal, you can divide the total (185g) by 5. That means each portion is 37g each. To find the total weight of the yogurt, we multiply by the number of portions, either 2 or 3. That would be your result.

Answer:
x = 24
Step-by-step explanation:
First, substitute x = -6y into the top equation:
-6y + 3y = 12
-3y = 12
Divide both sides by -3, and you get:
y = -4
Now, you plug in the y value to the second equation:
x = -6(-4)
x =24
Given :
[tex]{ \longrightarrow\qquad \sf x + 3y = 12 \: –––– \sf \: (i)}[/tex]
⠀
[tex]{ \longrightarrow\qquad \sf x = - 6y \: –––– \sf \: (ii)}[/tex]
⠀
(i) – (ii) we get :
⠀
[tex]{ \longrightarrow \qquad \sf \: {x + 3y -x = 12 - ( - 6y)}}[/tex]
⠀
[tex]{ \longrightarrow \qquad \sf \: { \cancel{x} + 3y \: \cancel{ - \: x }= 12 + 6y}}[/tex]
⠀
[tex]{ \longrightarrow \qquad \sf \: { 3y - 6y = 12 }}[/tex]
⠀
[tex]{ \longrightarrow \qquad \sf \: { - \: 3y = 12 }}[/tex]
⠀
[tex]{ \longrightarrow \qquad \sf {- \: y = \dfrac{12}{3} }}[/tex]
⠀
[tex]{ \longrightarrow \qquad \bf \: { y = - \: 4 }}[/tex]
⠀
Now, Substituing the value of y in equation (i) :
⠀
[tex] \longrightarrow \qquad \sf{x + 3( - 4)= 12}[/tex]
⠀
[tex] \longrightarrow \qquad \sf{x - 12= 12}[/tex]
⠀
[tex] \longrightarrow \qquad \sf{x = 12 + 12}[/tex]
⠀
[tex]\longrightarrow \qquad \bf{x = 24}[/tex]
⠀

find x with reason(s)
Answer:
Well we know this is a parallelogram
-A theorem states that if both opposite side of a quadrilateral (4 sided shape) are congruent then it’s a parrlelogram.
-We also know this is a rhombus becuase all sides are congruent and has no right angle present. A theorem to support this is, If two consecutive sides of a parallelogram are congruent, then the parallelogram is a a rhombus.
So we’re trying to find x.
A theorem states that “The diagonals of a rhombus bisects two angles of the rhombus.”
Bisect means cut in a way that both angles are equal.
That means the two angles given have to be equal to each other.
We can make an equation.
110-x = x
Now solve
2x= 110
X= 55
X would equal 55
x=55

In the adjoining equilateral [tex] \triangle[/tex] ABC , AD ⊥ BC and AC = 2a units. Prove that sin 60° = [tex] \sf{ \frac{ \sqrt{ 3} }{2} }[/tex] .
Answer:
See Below.
Step-by-step explanation:
Since ΔABC is an equilateral triangle, this means that ∠A, ∠B, and ∠C all measure 60°.
Furthermore, all sides of the triangle measure 2a.
We know that AD⊥BC. Since this is an equilateral triangle, any altitude will be a perpendicular bisector. Therefore, BD = DC, ∠CAD = 30° and ∠C = 60°.
Additionally, the measures of the segments are: BD = DC = (2a) / 2 = a.
Let’s use the right triangle on the right. Here, we have that DC = a and AC = 2a.
Recall that sine is the ratio of the opposite side to the hypotenuse. Therefore, sin(C) or sin(60°) will be AD / AC. We can find AD using the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
a is DC, b is AD, and c is AC.
Substitute in appropriate values:
[tex]a^2+(AD)^2=(2a)^2[/tex]
Solve for AD:
[tex]\displaystyle \begin{aligned} a^2+(AD)^2&=4a^2\\(AD)^2&=3a^2\\AD&=\sqrt{3a^2}=a\sqrt{3}\end{aligned}[/tex]
Sine is the ratio of the opposite to the hypotenuse:
[tex]\displaystyle \sin(C)=\sin(60\textdegree)=\frac{\text{opposite}}{\text{hypotenuse}}[/tex]
Substitute:
[tex]\displaystyle \sin(60\textdegree)=\frac{AD}{AC} = \frac{a\sqrt{3}}{2a}[/tex]
Simplify. Hence, regardless of the value of a:
[tex]\displaystyle \sin(60^\circ)=\frac{\sqrt3}{2}[/tex]

The town of KnowWearSpatial, U.S.A. Operates a rubbish waste disposal facility that is overloaded if its 4749 households discard waste with weights having a mean that exceeds 27.21 lb/wk. For many different weeks, it is found that the samples of 4749 households have weights that are normally distributed with a mean of 26.86 lb and a standard deviation of 12.82 lb. What is the proportion of weeks in which the waste disposal facility is overloaded? P(M > 27.21) =
Answer:
0.48911
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score, = 27.21 Ib
μ is the population mean = 26.86 lb
σ is the population standard deviation. = 12.82 lb
z = 0.027301
Probability value from Z-Table:
P(x<27.21) = 0.51089
P(x>27.21) = 1 - P(x<27.21) = 0.48911
The proportion of weeks in which the waste disposal facility is overloaded is
0.48911

How many gallons of paint will you need in order to paint a wall that is 42 feet wide and 27 feet high if one gallon will cover 200 square feet?
Answer:42 x27
Step-by-step explanation:Calculate how much paint and primer you need by entering the dimensions of your room below. Estimate how many gallons are needed based on average paint/primer coverage. Optionally, include ceiling paint in your estimate.
The number of gallons that are needed will be 6 gallons.
The number of gallons of paint that will be needed in order to paint a wall that is 42 feet wide and 27 feet high if one gallon will cover 200 square feet will be:
= (27 × 42) / 200
= 1134 / 200
