Answer:
Area of carpet = 177.625 ft²
Step-by-step explanation:
Given:
Length of room = [tex]14\frac{1}{2}[/tex] = 14.5 ft
Width of room = [tex]12\frac{1}{4}[/tex] = 12.25 ft
Find:
Area of carpet
Computation:
Area of carpet = lb
Area of carpet = (14.5)(12.25)
Area of carpet = 177.625 ft²
Micheal estimation = 15.5 x 12.25 = 189.875
Tracy estimation = 12.25 x 15.5 = 189.875
Both wrong.

what is the solution 2x-y=4 -4+2y=-8
Answer:
x= −1 /2 , y−4
Step-by-step explanation:
write a two-step equation that can be solved using the addition property of equality and the division property of equality.
Answer:
8x-14=26
Step-by-step explanation:
To solve this equation you first have to add 14 to both sides to cancel the -14 from the left side. Then you have to divide both sides by 8 to cancel out the 8 in front of the x and to get x alone. Then you have your answer. The answer to 8x-14=26 is x=5.
Line a and b are perpendicular lines.If line a is represented by y=s/t x+10 and line b is represented by y=q/r -4 where s,t,q and r are integers and t and r are not equal to zero which statement is always true
Answer:
The options are not shown, so i will answer in a general way.
First, for a line of the form:
y = a*x + b
All the perpendicular lines will have a slope of -(1/a), then we can write a general perpendicular line as:
y = -(1/a)*x + c.
In this problem we have the perpendicular lines:
y=(s/t)*x+10
y = (q/r)*x - 4
Because those lines are perpendicular, we must have that:
(q/r) = -(1/(s/t)) = -(t/s)
q/r = -t/s
and we knew that s, t, q and r are integers (where t and r can not be equal to zero), and because of this relation, where we can see that in the denominator at the right we have the integer s, we can conclude that s can not be zero (we can not divide by zero).
And we know that t and s are both different than zero, then:
-t/s ≠ 0.
This means that:
q/r ≠ 0
And from this, we can conclude that q is different than zero.

sec 16° cosec 74° - cot 74° tan 16°
Answer:
1.
Step-by-step explanation:
sec 16° cosec 74° - cot 74° tan 16°
= 1/ cos 16 * 1/ sin 74 - 1/tan 74 * tan16
= 1/ cos16 sin 74 - cos74/ sin74 * sin 16 / cos 16
Now cos 16 = sin 74 and sin 16 = cos 74 (supplementary angles) so:
= 1 / cos^2 16 - sin 16/cos 16 * sin 16 / cos 16
=( 1 - sin ^2 16 )/ cos^2 16
= cos^2 16 / cos^2 16
= 1.
Add 2x4 - 6x3 + 5x to the difference between 9x3 + 8x2 - 2 and 4x4 - 2x2 + 8x - 5.
Simplify (x3 + 3x2 + 5x – 4) – (3x3 – 8x2 – 5x + 6)
The first thing I have to do is take that "minus" sign through the parentheses containing the second polynomial. Some students find it helpful to put a "1" in front of the parentheses, to help them keep track of the minus sign.
Here's what the subtraction looks like, when working horizontally:
(x3 + 3x2 + 5x – 4) – (3x3 – 8x2 – 5x + 6)
(x3 + 3x2 + 5x – 4) – 1(3x3 – 8x2 – 5x + 6)
(x3 + 3x2 + 5x – 4) – 1(3x3) – 1 (–8x2) – 1(–5x) – 1(6)
x3 + 3x2 + 5x – 4 – 3x3 + 8x2 + 5x – 6
x3 – 3x3 + 3x2 + 8x2 + 5x + 5x – 4 – 6
–2x3 + 11x2 + 10x –10
And here's what the subtraction looks like, when going vertically:
x
3
−(3x
3
+3x
2
−8x
2
+5x
−5x
−4
+6)
In the horizontal addition (above), you may have noticed that running the negative through the parentheses changed the sign on each and every term inside those parentheses. The shortcut when working vertically is to not bother writing in the subtaction sign or the parentheses; instead, write the second polynomial in the second row, and then just flip all the signs in that row, "plus" to "minus" and "minus" to "plus".

please answer fast!!! drag each figure to show if it is similar to the figure shown or why it is not similar
Answer:
The similar figures are shown in the attached drawing created with Microsoft Visio;
The similar figures are the rectangles in figures 2, and 5
Step-by-step explanation:
The given figure is a rectangle with dimensions of 3 yd. by 9 yd., therefore the length = 3 × The width of the rectangle
1) The 9 yd. by 18 yd. figure is a rectangle with the length = 2 × The width of the rectangle, therefore, the figure is not similar to the given rectangle
2) The 3 yd. by 1 yd. figure is a rectangle with the width = 3 × The length of the rectangle, therefore, the figure is similar to the given rectangle
3) The figure is a trapezium, while the given figure is a rectangle, therefore, they are not similar
4) The 6 yd. by 3 yd. figure is a rectangle with the width = 2 × The length of the rectangle, therefore, the figure is not similar to the given rectangle
5) The 6 yd. by 18 yd. figure is a rectangle with the length = 3 × The width of the rectangle, therefore, the figure is similar to the given rectangle
6) The 2 yd. by 8 yd. figure is a rectangle with the length = 4 × The width of the rectangle, therefore, the figure is not similar to the given rectangle

A salesman's commission is directly proportional to his total sales. If the commission is $100 for $1000 in sales, find the commission for $1750 in sales.
The commission of the salesmen with the given ratio will be $175.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
The commission is $100 for $1000 in sales.
Ratio of commission to sales = 100/1000 = 0.1
With the same ratio,
Commission/1750 = 0.1
Commission = 1750 x 0.1 = $175
Hence "The commission of the salesmen with the given ratio will be $175".

The second hand of a clock is 10 inches long. Find the linear velocity of the tip of the second hand
Answer:
10 inches/hour
Step-by-step explanation:
The tip moves clockwise in a circle of radius 10 inches. The linear velocity is v = rω, where r is the radius and ω the angular velocity.
This comes out to v = (10 inches)(1 revolution per hour) = 10 inches/hour
