Answer:
The relation is c = 3.519g.
Step-by-step explanation:
This is direct variation.
c = kg where k is the constant of variation.
Substituting the given values:
190 = k * 54
so the constant of variation is:
k = 190/54 = 3.519 to nearest thousandth,
and the equation is:
c = 3.519g.

A motor center carries out servicing of cars, which includes the replacement of parts.
Three service technicians can each do 5 services per day . Normally they work Monday to Friday, but
sometimes one technician will also work on Saturday.
Each car requires 1 air filter, 1 oil filter, 1 quantity of engine oil and 4 spark plugs.
The parts are purchased in bulk, and come in boxes containing the quantities shown below.
Air filter............. 8 per box
Oil filter ............ 20 per box
Engine oil ......... 4 per box
Spark plugs ...... 80 per box
How many boxes of each item is it necessary to buy each week, if the motor center is to carry out the maximum possible number of services?
Answer:
1 box of spark plugs, 3 air filter boxes, 1 oil filter box, and 5 boxes of engine oil
Step-by-step explanation:
the max amount of services that can be done is about 20 per week, including the one on Saturday. so u just multiply the amount needed by the 20 possible services and check to see the amount that comes in each box, then get as many as needed

Isosceles triangle ABC contains angle bisectors segment BF, segment AD, and segment CE that intersect at X.
If segment BA is congruent to segment BC and m∠BCA = 48°, what is m∠CXA?
132°
96°
66°
24°
Answer:
The measure of angle CXA is 134°
Step-by-step explanation:
* Lets explain how to solve the problem
- Triangle ABC is an isosceles triangle where AB = BC
∵ AB = BC
- The base angles in the isosceles triangle are congruent
∴ m∠BAC = m∠BCA
∵ m∠ BCA = 46° ⇒ given
∴ m∠ BAC = 46°
- The sum of the measures of the interior angles in any triangle is 180°
∵ m∠BAC + m∠BCA + m∠ABC = 180°
- Substitute the values of angle BAC and BCA in the equation above
∴ 46 + 46 + m∠ABC = 180
∴ 92 + m∠ABC = 180
- Subtract 92 from both sides
∴ m∠ABC = 88°
- BF , AD , CE are bisectors segments of angles B , A , C and they are
intersected at point X
∵ CE bisects ∠BCA
∵ X ∈ CE
∴ m∠XCA = 1/2 m∠BCA
∴ m∠XCA = 1/2 (46) = 23°
∵ AD bisects ∠BAC
∵ X ∈ AD
∴ m∠XAC = 1/2 m∠BAC
∴ m∠XAC = 1/2 (46) = 23°
- In Δ AXC
∵ m∠XAC = 23° ⇒ proved
∵ m∠XCA = 23° ⇒ proved
∵ m∠CXA + m∠XAC + m∠XCA = 180° ⇒ interior angles of Δ
Substitute the values of angles XAC and XCA
∴ m∠AXC + 23 + 23 = 180
∴ m∠CXA + 46 = 180
- Subtract 46 from both sides
∴ m∠CXA = 134°
* The measure of angle CXA is 134°
Answer: I also have this question and because everybody is saying 134 I believe it is 132. So I hope this helps.

your answer as a fraction in simplest terms. Then, express the labeled angle in radian
measure,
100'
Let's consider what the problem wants us to find:
fractional part covered by the labeled angleangle in radiansLet's find the fractional part:
⇒ the fractional part is equal:
[tex]\frac{degree-covered-by-angle}{total-angle} =\frac{100}{180} =\frac{2*2*5*5}{2*2*3*3*5} =\frac{5}{3*3} =\frac{5}{9}[/tex]
Answer: The angle 100 degrees covers 5/9 of a semicircle.
Let's find the angle measure in radians:
⇒ we know that [tex]2\pi[/tex] radians are equal to 360 degrees
⇒ to convert any degree to radians, you must multiply [tex]\frac{\pi }{180}[/tex]
so [tex]100*\frac{\pi }{180} =\frac{100\pi }{180} =\frac{10}{18} \pi =\frac{5}{9} \pi[/tex]
Answer: The angle 100 degrees in radians is [tex]\frac{5}{9} \pi[/tex] which in terms of [tex]\pi[/tex] is

The equation of line is y = ( 1/2 ) mv² , where m is the mass of the student and y is the kinetic energy
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let y represent the kinetic energy and mass is m
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
The equation for kinetic energy is K = ( 1/2 )mv²
The constant speed v = 3 m/s
So , the linear equation is
y = { 121.5 , 162 , 202.5 , 243 , 288 , 328.5 }
x = { 27 , 36 , 45 , 54 , 64 , 73 }
The slope m = y / x
On simplifying , we get
m = 121.5 / 27 = 4.5
And , the equation of line is
y - 121.5 = 4.5 ( x - 27 )
Adding 121.5 on both sides , we get
y = 4.5x
Now , plotting the points on the graph , we get a straight line
Hence , the equation of line is solved and the graph is plotted

find the values of a and b such that x squared-4x+9= (x+a) squared+b
Answer:
a = - 2, b = 5
Step-by-step explanation:
expand the right side using FOIL and compare the coefficients of like terms on both sides.
(x + a)² + b
= x² + 2ax + a² + b
compare terms with x² - 4x + 9
coefficients of x- term
- 2a = 4 ( divide both sides by - 2 )
a = - 2
compare constant terms
a² + b = 9
(- 2)² + b = 9
4 + b = 9 ( subtract 4 from both sides )
b = 5
