An auto mechanic charges (C) an initial fee of $50 and then $40 per hour. If (h) represents hours, how much will the mechanic ch

liraira [26]

The charging rate equation for the auto mechanic is C = 50 + 40h(50 for the initial fee and 40 times h for every hour). If he works 10 hours in one day we have to plug in 10 into the hours spot, h.

C = 50 + 40(10)

Now we solve for C

C = 50 + 400

C = 450

The auto mechanic charges $450 for 10 hours.

Alex

Answer:

(5,4)

Step-by-step explanation:

We have that the longer base of an isosceles trapezoid joins points (-3, -2) and (7, -2), and one endpoint of the shorter base is (-1, 4).

The best way to find the coordinates of the other endpoint is to draw or sketch the figure on a coordinate grid.

From the graph in the attachment the coordinates of the other endpoints is (5,4).

Answer:

$5,811.95\ m^2$ of fabric.

Step-by-step explanation:

-The amount of fabric needed is equivalent to the area of the two gardens.

-We calculate the combined areas as:

$A=A_s+A_b\\\\=\pi r^2+\pi R^2\\\\=\pi(25^2+35^2)\\\\=1850\pi \ m^2\\\\=5811.95\ m^2$

Hence, 5811.95 sq meters of fabric will be needed to cover the area of both gardens.

Two-thirds a number x plus 6 is 10 written as a equation

mestny [16]

Answer:

$\frac{2}{3}x + 6 = 10$

Step-by-step explanation:

Required

Write as equation

Taking the statement one at a time, we have

Two third of x: $\frac{2}{3}x$

Plus 6: $\frac{2}{3}x + 6$

is 10: $\frac{2}{3}x + 6 = 10$

Hence, the equivalent of the given statement is $\frac{2}{3}x + 6 = 10$
