Step-by-step explanation:
A contractor bought 12.6 ft? of sheet metal. He has used 2.1 ft? so far and has $210 worth of sheet metal remaining. The equation 12.6x-2.1x = 210 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?
Answer:
$20
Step-by-step explanation:
12.6x-2.1x=210
10.5x=210
x=210/10.5
x=20
suppose that 11 inches of wire costs 55 cents how many inches of wire can be bought for 25 cents
Answer:
5 inches of wire costs 25 cents.
Step-by-step explanation:
To answer this question, we want to find the unit price per inch of wire. Therefore, we need to divide the cost of the 11 inches (55) by the length of the wire (11):
55 / 11 = 5
So, 1 inch of wire costs 5 cents.
Now, to see how many inches can be bought with 25 cents, multiply 5 times both the 1 inch and 5 cents, which are the unit price to get:
5 inches of wire costs 25 cents.

The heights of Karina, Miya and Clint were 155cm, 158cm, and 161cm respectively. What is the height of Roger if the mean of all of them is 158cm?
Answer:
The height of Roger is 158cm
Step-by-step explanation:
All of them=158cm
They are 4.So,158^4=632cm
Height of 3 persons=155cm+158cm+161cm=474cm
Therefore the height of Roger is 632cm-474cm=158cm
The height of Roger with the mean of all of them is given is 158 cm.
Given that, the heights of Karina, Miya and Clint were 155cm, 158cm, and 161cm respectively.
What is mean?In statistics, the mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations).
Let the height of Roger be R.
Mean= 158 cm
We know that, mean =Sum of all the observations/Number of observations
⇒ (155+158+161+R)/4 =158
⇒ 474+R=632
⇒ R=632-474
⇒ R=158 cm
Hence, the height of Roger with the mean of all of them is given is 158 cm.

Answer:
Last one hard to explain
can someone help me?
Step-by-step explanation:
a)
a whole circle represents always 360 degrees.
we see the angle J is 72 degrees. the angle K is 90 degrees.
that leaves us for M and L together :
360 - 72 - 90 = 198 degrees.
we now know that twice as many people voted for L as for M. that means the angle L is twice as big as the angle M
on other words : L = 2M
and when we now say
198 = L + M
this means
198 = 2M + M = 3M
M = 66 degrees
and L is then 2M = 2×66 = 132 degrees
b)
again, the whole circle is 360 degrees.
J covers 72 of these 360 degrees.
that is 72/360 of all voting people.
72/360 = 1/5
the total of all voting people was 15840.
so, 1/5 of 15840 is
15840/5 = 3168
that means 3168 people voted for J.

The modal represent the division is 6 ÷ 6/9 = 9.
What is division?One of the most fundamental operations in arithmetic is division, in which a larger number is divided into smaller groups with the same number of items. Dividing a large group into smaller groups so that each group has the same number of items is called division. In math, it is an operation that equalizes sharing and grouping.
Given the number line in figure,
shows the number is divided in 9 equal parts
1/9, 2/9, 3/9, ..........9/9
and from 0 to 6/9 parts are marked,
there are 6 parts in 0 to 6/9
the division model for equation is
6 ÷ 6/9
and division is 6 ÷ 6/9 = 9

If l is parallel to m find the value of X (x+72)=(3x)
Answer:
x = 27°
Step-by-step explanation:
Given the lines are parallel you have a pair of same-side interior angles and these angles = 180°
x + 72 + 3x = 180
4x + 72 = 180
4x = 108
x = 108/4
x = 27°
The value of x will be 27 degree
The solution to the above problemGiven the lines are parallel you have a pair of same-side interior angles and these angles = 180°
x + 72 + 3x = 180

What is the slope of a line perpendicular to the line represented by the equation 2y=-6x+8
Answer:
First we need to solve the linear equation for y because we need to get the slope. Once we have the slope we need to convert it to its negative reciprocal, this means to just change the sign of the slope and flip it. The negative reciprocal is always perpendicular to the original slope.
2y = - 6x + 8
y = (-6x/2) + 8/2
y = - 3x + 4
The current slope is -3 or -3/1
The negative reciprocal is 1/3

Please answer for
m∠1 AND m∠2
Answer choices for m∠1:
50, 110, 70, 90
Answer choices for m∠2:
70, 110, 40, 140
Answer:
70°, 140°, 50°
Step-by-step explanation:
110° and the angle inside the triangle are adjacent angles and sum to 180°, so
angle inside triangle = 180° - 110° = 70°
The triangle on the left is isosceles ( 2 congruent sides ) then base angles are congruent
∠ 1 = angle inside triangle = 70°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 2 is an exterior angle of the triangle on the left, so
∠ 2 = 70° + 70° = 140°
∠ 2 is also an exterior angle of the triangle on the right, so
∠ 3 + 90° = 140° ( subtract 90° from both sides )
∠ 3 = 50°

−3
−1
1
3
Work Shown:
4x - 8 = -4
4x = -4+8
4x = 4
x = 4/4
x = 1
To check the answer, we replace x with 1 in the original equation. After simplifying, we should get the same thing on both sides
4x - 8 = -4
4(1) - 8 = -4
4 - 8 = -4
-4 = -4
The answer is confirmed.
true? I believe due to how it starts with positive 4 and is subtracted by -8 this conceding a negative number.
