Find the length of the unknown side. Round your answer to the nearest whole number.
A).7 m
B).9 m
C).10 m
D).12 m
Answers
Answer:
C). 10
Step-by-step explanation:
Using the Pythagorean theorem, a^2+b^2=c^2
We know the two sides (a and b) and are trying to find the hypotenuse (c).
Substitute the known values:
7^2+7^2=c^2
Simplify and solve:
49+49=c^2
98=c^2
sqrt(98)=c
c=9.899
Rounded to the nearest whole number would be 10

Answer:
The explanation on how to do them is down below. If you have anymore questions pls feel free to ask
Step-by-step explanation:
So for number one you just need to state the sentence under the lines back wards but starting Lines m and n......
For number two name two angles that are inside the parallel lines and for three the opposite name two that are basically verticle outside of the parallel lines.
For number four they are across from each so they are verticle and since they are verticle they are concurrent so the m of 2 is 125.
In number 5,4 and 7 are corresponding so the are equal.
In number 6 the angles are alternate interior so they are congruent.
In number 7, the angles are corresponding so they are congruent.
In number 8, the angles are alternate exterior so they are congruent.
In number 9, the angles are are verticle so the are congruent.
In number 10, the answer is supplementary because on the top and bottom they add up to 180 degrees. And it part b 2 and 3 are adjacent and supplementary, so you subtract 119 from 180 and you get 61.

Answer:
new answer with estimate= 10 old answer= [tex]9.24[/tex]
Step-by-step explanation:
Use this method percent proportion
[tex]\frac{Percent}{100} = \frac{Part}{Whole}[/tex] or [tex]\frac{Percent}{100} = \frac{is}{of}[/tex]
Answer:
12% of 77
[tex]\frac{12}{100} = \frac{x}{77} = \frac{100x}{100} = \frac{924}{100} x = 9.24[/tex]
Steps:
1. Make a proportion with the method percent proportion.
2. After setting up numbers in proportion cross-multiply.
3. Make 100x because we don't know the value of x.
4. After multiplying 12 x 77 you should've gotten 924.
5. After cross-multiplying divide your new proportion.
6. [tex]x= 9.24[/tex] estimate = 10
now I'm not sure if those number in your question is your new estimate answer but since 9.24 is close to 10 your answer will be 10

Answers
Answer:
22ft^3
Step-by-step explanation:
Find the volume of one wooden cube block. Each of the edge length is 1/2
Volume of cube = l x w x h
l = 1/2 w = 1/2 h = 1/2
1/2 x 1/2 x 1/2 = 1/8
Then find the volume of the total box with how much total wooden blocks there are.
They are 176 wooden blocks.
Volume of one wooden cube block x the total number of wooden cube blocks = total volume of box.
So you do 1/8 x 176 and with that, the volume is 22ft^3.

1. Add 28 to both sides:

[tex]5x - 28 + 28 = 232 + 28[/tex]
2. Simplify:
[tex](adding, add again) = 5x =260[/tex]
3. Divide both sides by the same factor
[tex]5x = 260[/tex]
[tex]\frac{5x}{5} = \frac{260}{5}[/tex]

4: 321.5cm²
5: Length of fencing = 62.46cm, Area of Yard: 232cm²
6: Area of 1 sign: 3950cm². Paint cans needed: 237
Step-by-step explanation:
4:
Area of Machine = Area of Square - 1/4 Area of Circle taken away
Area of Machine = (20x20) - 1/4(π10²)
Area of Machine = 400 - 1/4(3.14 x 100)
Area of Machine = 400 - 1/4(314)
Area of Machine = 400 - 78.5 = 321.5cm²
5: The perimeter of this figure is the length of fencing needed. The area of the yard can be figured out:
Perimeter: We're missing one side. So what we need to see here, is that the figure has a hidden triangle. Do you see it? its a missing right angle triangle, and we can use the Pythagorean theorem to find the hypotenuse, which is the missing side:
a² + b² = c²
16² + 7² = c²
256 + 49 = c²
305 = c²
c ≅ 17.46cm
now that we know the last dimension of the trapezoid, the Perimeter is known to be 11 + 16 + 18 + 17.46 = 62.46cm
Area = 1/2(b1+b2) x h
Area = 1/2(11 + 18) x 16
Area = 14.5 x 16 = 232cm²
6:
Area of 1 Sign = Area of rectangle + Area of Triangle
Area of 1 Sign = (90x30) + 1/2(50 x 50)
Area of 1 Sign = 2700 + 25x50
Area of 1 Sign = 2700 + 1250 = 3950cm²
.: area of 6 signs will be 6 x 3950 = 23,700cm²
If one can of paint covers 1 squared meter, then it covers 100 squares cm. So it will take 23700/100 = 237 paint cans to cover all 6 signs :)

Margaret and Donovan are twins. They have each kept track of their heights every year since they were 5.
Donovan wrote an equation to track his height: h = 105 + 4.25(a - 5)
Based on the evidence shown, which statement correctly compares the twins' rates of growth?
Answers
Don’t even know I need help
Myself
Answer: B
Explanation:What we know:
Donovan's height can be expressed through the equation H = 105 + 4.25(a - 5) where H is height and a is ageMargaret's height is expressed through a given tableHow to solve:
We need to create a table for Donovan's height, compare it to Margaret's table, and then choose the appropriate statement. H will represent height, and a will represent age. B and c are constant values, and x is a coefficient to a-c
Process:Part 1 - DataSimplifying equation
Set up equation H = 105 + 4.25(a - 5)
Distribute H = 105 + (4.25a - 21.25)
Age 5
Set up equation H = 105 + (4.25a - 21.25)
Substitute H = 105 + [(4.25*5) - 21.25]
Simplify H = 105 + (21.25 - 21.25)
Simplify H = 105
Age 6
Set up equation H = 105 + (4.25a - 21.25)
Substitute H = 105 + [(4.25*6) - 21.25]
Simplify H = 105 + (25.5 - 21.25 )
Subtract H = 105 + 4.25
Solve H = 109.25
Age 7
Set up equation H = 105 + (4.25a - 21.25)
Substitute H = 105 + [(4.25*7) - 21.25]
Simplify H = 105 + (29.75 - 21.25)
Subtract H = 105 + 8.5
Solve H = 113.5
Continue for the following ages (8-10)
Part 2 - Table Comparison1. Create a table for both sets of data. Example:
______________________________________________
Age | 5 | 6 | 7 | 8 | 9 | 10 |
Mar. height (cm) | 101 | 105 | 109 | 113 | 117 | 121 |
Don. height (cm) | 105 | 109.25 | 113.5 | 117.75 | 122 | 126. 25 |
______________________________________________
2. Find which statement applies
2a. Margaret did not grow faster than Donovan
2b. Donovan did grow faster than Margaret
2c. Margaret and Donovan did not grow at the same rate
2d. There is enough data to draw a conclusion
Solution: BCheck:
We came to this conclusion by putting Donovan's data into a chart. We can check by writing an equation for Margaret's height. Then, use that equation with Donovan's to see the difference
Margaret's equation:
H = 4a + 81
Comparison (using ages 8 & 9):
8:
H= 4a + 81 | H = 105 + (4.25a - 21.25)
H = (4*8) + 81 | H = 105 + [(4.25*8) - 21.25)
H = 32 + 81 | H = 105 + 12.75
H = 113 | H = 117.75
9:
H = 117 | H = 122
________________________
113 < 117.75
117 < 122
Because the statement still holds true, answer B is correct.
In 2016, a maglev train in Japan traveled 1.1 miles in 1045 seconds.
A picture of a Maglev train is shown. The caption reads Maglev trains use magnets to hover above the tracks. This helps them reach extraordinary speeds.
Question 1
Part A
Find the speed of the train in miles per hour.+
Answers
Answer: ~3.8 mph (see below)
Explanation:What we know:
We need to find the speed of the train in miles per hour (mph)The train is traveling 1.1 miles per 1045 secondsThere are 3600 seconds in 1 hourHow to solve:
We need to find what number when multiplied with 1045, will equal 3600. The unknown will be a variable x, and the seconds will be represented with s. Then, we need to multiply this number with the value of the miles (m) to find how many miles are traveled in that hour (h).
Process:Finding X (in seconds)
Set up equation H = sx
Substitute 3600 = 1045x
Divide /1045 /1045
Solution 3.44497608 = x
Finding Miles
Set up equation mph = x(m/s)
Substitute mph = 3.44497608(1.1/1045)
Simplify mph = ~3.79/3600
Convert mph = ~3.8 miles per hour
Solution: ~3.8 mph (3.78947369 miles per 3600 seconds)
