a piece of metal is 1.167 inch thick. how thick would it be if someone milled 0.012 off one side and 0.065 off the other side?

Soloha48 [4]

Answer:
Remaining thickness = 1.09 in

Explanation:
1- getting the value of the milled thickness:
We are given that:
0.012 in was milled off one side
0.065 in was milled off the other sides
This means that:
Total milled thickness = 0.012 + 0.065 = 0.077 in

2- getting the remaining thickness:
Remaining thickness = original thickness - milled thickness
We have:
original thickness = 1.167 in
milled thickness = 0.077 in
Therefore:
Remaining thickness = 1.167 - 0.077 = 1.09 in

Hope this helps :)

HELP! Consider the function represented by the graph. On a coordinate plane, a straight line with a negative slope begins on the

ch4aika [34]

Answer:

{ x | x ≥ 0 }

Step-by-step explanation:

Given,

There is a straight line started from (0, 9) and passes through (8, 1),

∵ In the coordinate plan, the values of x are arranged in increasing order to the right side of the y-axis,

Thus, the line is defined for all real values of x greater than 0,

Hence, Domain of the line = All real numbers greater than equal to 0,

i.e. { x | x ≥ 0 }

Thus, FIRST OPTION is correct.

Anestetic [448]

Answer:

The number of small mowers are 19 and the large mowers are 11.

Step-by-step explanation:

Given:

A garden supply store sells two types of lawn mowers. Total sales of mowers for the year were $8379.70. The total number of mowers sold the 30. The small mower cost $249.99 and the large mower costs $329.99.

Now, to find the number of each type of mower sold.

Let the number of small mower be $x.$

And the number of large mower be $y.$

So, total number of mowers are:

$x+y=30$

$x=30-y\ \ \ ....(1)$

Now, the total sales of mowers are:

$249.99(x)+329.99(y)=8379.70$

Substituting the value of $x$ from equation (1) we get:

$249.99(30-y)+329.99y=8379.70$

$7499.7-249.99y+329.99y=8379.70$

$7499.7+80y=8379.70$

Subtracting both sides by 7499.7 we get:

$80y=880$

Dividing both sides by 80 we get:

$y=11.$

The number of large mower = 11.

Now, to get the number of small mowers we substitute the value of $y$ in equation ( 1 ):

$x=30-y\\x=30-11\\x=19.$

The number of small mower = 19.

Therefore, the number of small mowers are 19 and the large mowers are 11.
