Lax varies directly with y. When x=32,y=8. If y=44, what does x equal?

1 answer:

8 0

X varies directly with y means x=ky

k is the constant of variation

given when x=32 and y=8
32=8k
divide by 8
4=k

so
x=4y

when y=44

x=4(44)
x=176

x=176 when y=44

Robert and his coworkers brought 11 work trucks to a service station for oil changes. While there they also put 6 gallons of gas

Free_Kalibri [48]

Answer:

The cost of an oil change for 1 truck was $42

Step-by-step explanation:

Let

x -----> the cost of an oil change for 1 truck

y -----> the cost of gas for 1 truck

z ----> the total bill

we know that

$z=11[x+y]$

we have

$z=\$694.32$

$y=(6)(3.52)=\$21.12$

substitute and solve for x

$694.32=11[x+21.12]$

$x=(694.32/11)-21.12$

$x=\$42$

I need help with this math question. What is the Area of this shape?

zubka84 [21]

Answer:

A=174

Step-by-step explanation:

Step 1: Separate the figure into two separate shapes, a triangle and a square

Step 2: Find the dimensions of the triangle and square.

Square - l=12 w=12

Triangle - h=5, b=12. (The height was found by subtracting the length of the square (12) from the total length (17).

Step 3: Solve by using formulas

A=(5)(12)/2=30

A=12*12=144

Step 4: Add the parts together

144+30=174

A=174
