Answer:
x = - 20, h = 34
Step-by-step explanation:
i can't tell ypou what the class period is, but for -x = 20, multiply each side by -1, then you get x = -20
-32 = 2-h
+32 . +32
0=34-h
+h . +h
34=h
flip

To find the area of a rectangle do A = bh
When you substitute 4/6 for base and 3/5 for height it will be A = 4/6 x 3/5
This means the area is 2/5
Answer:
2/5 cm^2
Step-by-step explanation:
The area of a rectangle is found by
A = l*w
A = 4/6 * 3/5
Rewriting
=4/5 * 3/6
= 4/5 *1/2
= 2/5 cm^2
What is the area of the polygon shown below? (in the image). A. 322 mm^2 B. 364 mm^2 C. 520 mm^2 D. 584 mm^2 Show all work please!
Answer:
A.
Step-by-step explanation:
Find the area of the triangle: 26-20=6. 14x6=84/2=42. Now that we calculated the triangle's area, we need to find out the rectangle's. 20x14=280. Add them up: 280+42=322 mm^2. Triangle: b x h/2. Rectangle: l x h.
The area of a 2D form is the amount of space within its perimeter. The area of the given figure is 322 mm². The correct option is A.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The given figure can be broken into a rectangle and a right-angle triangle, in order to calculate the area of the given polygon.
The area of the rectangle with a length of 20mm and height of 14 mm is,
Area of the rectangle = 20mm × 14mm
= 280 mm²
The area of the right-angled triangle with a base length of 6mm and height of 14 mm is,
Area of the triangle = (1/2) × 6mm × 14mm
= 42 mm²
Now, the total area of the given figure can be written as,
The total area of the given figure
= Area of the rectangle + Area of the triangle
= 280 mm² + 42 mm²
= 322 mm²
Hence, the area of the given figure is 322 mm².

m∠1=36°, m∠4=49°, m∠6=131°. Find m∠9. A. 144 B. 242 C. 216 D. 36
Answer:
<9 =144
Step-by-step explanation:
<1 + <4 + < 6 + <9 = 360
36+ 49+ 131 + <9 = 360
216 + < 9 = 360
< 9 = 360-216
<9 =144
Answer:
A. 144
Step-by-step explanation:
Since m<6 + m<4 = 131 + 49 = 180, then FE is a line.
Angles 1 and 9 are a linear pair, so they are supplementary.
m<9 + m<1 = 180
m<9 + 36 = 180
m<9 = 144
At the same time, Sam and Fred who are 168 miles apart begin moving toward each other. Find the number of hours before they meet if Sam runs 12 mph and Fred runs 9 mph.
Answer: 8 hours
Step-by-step explanation:
Let x be the time before they meet ( in hours)
Speed of Sam = 12 mph
Sped of Fred = 9 mph
Distance = Speed × time
Distance covered by Sam in x hours = 12x
Distance covered by Fred in x hours = 9x
(Distance) (rate1) (time1) (rate2) (time2)
Total distance between them: 168 = 12 x + 9 x
[tex]\Rightarrow\ 168= 21x\\\\\Rightarrow\ x=\dfrac{168}{21}=8[/tex]
Hence, the number of hours before they meet if Sam runs 12 mph and Fred runs 9 mph. = 8

Answer:
Angle MON is equal to 130 degrees.
Step-by-step explanation:
We are told LON is 180 degrees.
Angles LOM and MON are supplementary meaning they add to 180 degrees.
Using this information we know 12x+120=180.
We can use the subtractive property of equality to subtract 120 from both sides.
Do thins we get 12x=60.
Using the division property of equality we can divide both sides by 12 to get x=5.
We can then use the substitution property of equality to get MNO=8(5)+90.
We can then simplify to get MNO=130.

b) What percentage were *not* children
Answer: A) 67[tex]\frac{11}{117}[/tex] (or) 67.09
B) No. of people neither children nor women
= 468-(314+75)
= 79
= [tex]\frac{79}{468}[/tex]*100
= 16[tex]\frac{103}{117}[/tex] (or) 16.88
I hope it helps. Have a great day :)
Answer:
a) = 67.10 % or 67.09%
b) = 84.10% or 83.97%
Step-by-step explanation:
a = (314/468)*100 = 67.094017094 %
b = (393/468)*100 = 83.9743589744 % (edited 393)
To find b we have to can use simple subtraction to find Men = m = ?
If Women = w = 314 and Children = c = 75
Eliminate the (w = 314) with (c=75) from total to find (m=?)
w+c+m= 468
c+m = 468-w = 468-314 = 154
m = 154-c = 154-75 = 79
m = 79
b) Total sum that were not children = w+m = 314 + 79 = 393
or = 468-314 = 154
then 154 - 79 = 75
with = 468-75 = 393
then find percentage;
(393/468) * 100 = 83.9743589744

Solve for x. Show work plz
Step-by-step explanation:
Given,
RSTU is a parallelogram,
so, we need to find the value of x,
let's find it,
2x+15 = x+15 (opposite side of parallelogram are equal and parallel)
2x - x = 15-15
x=0
Therefore, the value of x is 0.
If you have doubt. then let's clear it by putting the value of x.
so, 2×0+15 = 0+15
15=15 {as already said that the sides are equal}
proved..
so, the value of x is 0.
Hope it helps.....
Answer:
x=0
Step-by-step explanation:
Assuming the two sides are equal length
2x+15 =x+15
Subtract 15 from each side
2x =x
Subtract x from each side
2x-x = x-x

During a certain 25-year period, the consumer price index (CPI) increased by 99%,but during the
next 25-year period, it increased by only 1%. Which of these conditions must have existed during the
second 25-year period?
A. Conflation
B. Deflation
C. Inflation
D. Stagnation
For the next 25-year period,(CPI) is increased by only 1% due to Inflation and Stagnation.
What is Stagnation ?
Stagnation is a situation of slow economic growth and relatively high unemployment (which basically means that aggregate production is reducing and some of the inputs of the economy, such capital or labor, are unemployed) , accompanied by rising prices, or inflation.
In terms of national accounting, it means a reduction in gross domestic product (GDP), with inflation (rise in all prices in the economy).
In terms of aggregate demand and supply models, stagnation is the result of a contraction of aggregate supply, which ceteris paribus, results in lower levels of production and higher prices.
Many theories have tried to explain this phenomena. Common interpretations link stagnation with and increase of the cost of production in the economy (that might be generated by an increase of gasoline for example), and its implications in the production (lower production because of higher costs), consequently unemployment and a rise of prices due to the increase of cost.
Here, During a certain 25-year period, the consumer price index (CPI) increased by 99% and during the next 25-year period, it increased by only 1% which shows slow economic growth which can be due to Inflation and Stagnation.

Answer:

Step-by-step explanation:
If US bisects the angle then
BUS = SUL
2x+10 = 3x-18
Subtract 2x from each side
2x+10 -2x = 3x-18-2x
10 = x-18
Add 18 to each side
10+18 =x
28 =x
We want to find BUL
BUL = BUS + SUL
2x+10 + 3x-18
5x-8
5*28 -8
140-8
132
Answer:
m<BUL=132
Step-by-step explanation:
Since US bisects <BUL, we know that <BUS ≅ <SUL
This is based on the angle bisector definition.
Hence, we can set up an equation to solve for x.
<BUS≅<SUL
2x+10=3x-18
Subtract 10 from both sides
2x+10-10=3x-18-10
2x=3x-28
Subtract 3x from both sides
2x-3x=3x-3x-28
-x=-28
Divide both sides by -1
x=28
m<BUL is the sum of m<BUS and m<SUL
m<BUL=m<BUS+m<SUL
m<BUS=2x+10
m<SUL=3x-18
Plug it in
m<BUL=2x+10+3x-18
Combine like terms
m<BUL=5x-8
Plug in 28 for x
m<BUL=5(28)-8
m<BUL=140-8
m<BUL=132

kristen and melissa spent 35% of their $32 on movie tickets. how much money did they spend
Answer:
11.2$
Step-by-step explanation:
Kristina and Melissa had 32$ at total
● 32$ => 100%
They have spent 35%
Let x be that amount
● x => 35%
●32 => 100
● x => 35
● x = (35×32)/100 = 11.2$
They have spent 11.2$
Answer:
They spent $20.80
Step-by-step explanation:
Since they had $32 and spent 35% of it you would do 32 * 35%
then you would get 11.2
now that is not the answer because that is just what 35% of 32 is
to get the answer you would then subtract 11.2 from 32 to get 20.8
and since this is a matter of money you would write 20.8 as $20.80.
