How many degrees are there in the "Department Store" angle? *
How many degrees are there in the "Gas Station" angle? *
Answers
Answer:
Department Store:
7(18.75)+8= 139.25
Gas Station:
18.75+22= 40.75
Step-by-step explanation:
The mistake is 7x+8+x+22 should not equal 90. It should equal 180 degrees because the two angles are supplementary angles. (It forms a straight line)
Correct equation and how to solve for X:
7x+8+x+22=180
8x+30= 180
8x= 150
x=18.75
Department Store:
7(18.75)+8= 139.25
Gas Station:
18.75+22= 40.75

In trapezoid MNPQ shown below, MN || QP, m&M = 108°, m&P = 4x - 5, and
mxQ = 3x + 21. What is the number of degrees in m«N.
Answers
Answer:
Answer:
The answer is below
Step-by-step explanation:
A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base. Also, the angles on the same leg of a trapezoid (adjacent angles) are supplementary (add up to 180°).
In trapezoid MNPQ:
∠M + ∠Q = 180° (angles on the same leg are supplementary)
108 + (3x + 21) = 180
3x + 129 = 180
3x = 51
x = 17
Also:
∠N + ∠P = 180° (angles on the same leg are supplementary)
∠N + (4x - 15) = 180
∠N = 180 - (4x - 15)
∠N = 180 - 4x + 15
∠N = 195 - 4x
substitute x = 17°:
∠N = 195 - 4(17)
∠N = 127°

The length of a rectangle is 5 inches longer than it is wide. If the perimeter is 38 inches, what are the dimensions of the rectangle?
The width, or shorter side is ______
inches.
The length, or longer side is _____
inches.
Answers
Answer:
shorter side = 7 in
longer side = 12 in
Step-by-step explanation:
Let w = width
then w + 5 = length
The perimeter of the rectangle = 2 widths + 2 lengths.
So, w + w + w + 5 + w + 5 = 38 or 2w +2(w + 5) = 38 are two ways to write the equation to solve the problem.
Now 4w + 10 = 38
4w = 28
w = 7
w + 5 = 7 + 5 = 12
shorter side = 7 in
longer side = 12 in
Check: 7 + 7 + 12 + 12 = 38 = perimeter

Answer:
12. median: AD; altitude: CE; midsegment: none
13. x = 2
Step-by-step explanation:
12. The median joins a vertex with the midpoint of the opposite side. Point D is identified as the midpoint of BC, so AD is the median.
An altitude is a segment from a vertex that is perpendicular to the opposite side. CE is an altitude of this triangle.
A midsegment joins midpoints of adjacent sides of the triangle. Only one midpoint (D) is identified in this triangle, so no midsegment can be named.
Additional comment: BF is an angle bisector. Perhaps that is what is intended in part (c). You may want to report this question to your teacher.

O bicicleta costa 420 de lei. Pretul ei se reduce cu 15%. Cat va costa bicicleta dupa reducere.
Answers
Answer:
The price of the bicycle after the discount is 357 lei
Step-by-step explanation:
The given question says, "The bicycle costs 420 lei. Its price is reduced by 15%. How much will the bike cost after the discount."
Cost price of the bicycle = 420 lei
Discount = 15%
We need to find the price of the bicycle after the discount. It can be calculated as follows :
[tex]P=420\times \dfrac{15}{100}\\\\=63[/tex]
Price = 420 -63
= 357 lei
Hence, the price of the bicycle after the discount is 357 lei.

1/10 of the counters in a bag are blue. 1/2 of the counters are red. 2/5 of the counters are yellow. Which of the ratios below shows the ratio of blue to red to yellow?
Answers
Answer:
well 1/10 are blue, 5/10 are red, and 4/10 are yellow.
1/10 blue
5/10 red
4/10 yellow
I don't really know how to answer this question but I hope me converting the ratios helps :)
Step-by-step explanation:
1/2 red
2/5 yellow
First, make it so that each if their whole (denominator, or the right side) is equal.
We already know that 2 and 5 are common factors of 10, so we get them to the number 10 by equal multiplication.
1/10 - blue
1/2(5) = 5/10 - red
2/5(2) = 4/10 - yellow
Now just take their numbers in order.

If a man walks at the rate of 3 feet per second, how many minutes will it take him to walk 5760 feet?
Answers
Answer:
32 minutes
Step-by-step explanation:
There are 60 seconds in a minute
That means we will need to know how many feet he walks in a minute
So we would do 3 x 60 which equals 180 so he walks 180 ft per miute
Now we need to figure out how many minutes it took for him to walk 5760 ft.
So we would do 5760 ÷ 180 which equals 32
So the aswer is 32 minutes for him to walk 5760 ft.

Answers
Answer:
the 9 in the tenths place is 10 times bigger than the one in the hundredths place
Step-by-step explanation:
The value of the 9 in the tenth place is "10 times" the value of the 9 in the hundredth place.
What is the place value strategy?Place value strategies are defined as math strategies that use to assist you in resolving your elementary math problems, using your place values, such as tens and hundreds.
The decimal we are examining is 3.9928.
The 9 in tenth place has a value of 0.9.
The value of 9 in the hundredth place is 0.09
The fraction of the 9 in the tenth place is now the 9 in the hundredth place.
To get this, simply multiply the value of 9 in the hundredth place by the value of 9 in the tenth place.
Mathematically, that would be;
0.09/0.9 = 0.1 = 1/10
This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place
So you can complete the statement by dragging and dropping "10 times" into the response area.

Answers
Answer:
5
Step-by-step explanation:
First, find the equation of the line:
put it in the form y = mx + b where m is the slope and b is the y-intercept
You already have m = 2, so y = 2x + b.
Then, since you know (1, 3) is a solution so you can plug x = 1 and y = 3 into the equation to find out what b is.
3 = 2 * 1 + b
3 = 2 + b
1 = b
This means the equation of the line is y = 2x + 1.
Then, since you're trying to find out what y is when x = 2, you can plug in x = 2 into the equation:
y = 2 * 2 + 1
y = 4 + 1
y = 5
5 is the answer
