Answer: x = 54
Step-by-step explanation:
Supplementary: two angles or arcs whose sum is 180 degrees.
One angle: x + 15 degrees
Second angle: 2x + 3 degrees.
180 degrees = 3x + 18
180 minus 18 = 162
162 divided by 3 = 54
x = 54
Hey there!
=> x + 15 + 2x + 3 = 90°
=> x + 2x + 3 - 15 = 90°
=> 3x - 12 = 90°
=> 3x = 90° + 12
=> 3x = 102°
=> [tex] \frac{3x}{3} = \frac{102}{3} [/tex]
=> [tex]x = \frac{102}{3} [/tex]
=> x = 34
Then,
=> x + 15 , 2x + 3 {add the value of x}
=> (34) + 15, 2(34) + 3
=> 34 + 15, 68 + 3
=> 49,71
∴ the angles are 49 and 71

HELP with this math problem please
Answer:
-1/4
Step-by-step explanation:
Since there is a positive and negative sign next to each other it would automatically become a negative sign so then your equation should be 1/2-3/4 now you would need to find the common denominator since 2 can go into 4 2x the equation would be 2/4-3/4 now you would subtract that to get -1/4

Q6: What is the measure of 2 if 1 is (2x - 3) and 2 is (8x)?
Answer:
168 degrees
Step-by-step explanation: first you would do (2x-3)+8x so you would have 10x-3 and that equals 180 degrees since its a straight angle. so you would do 10x-3=180 divide by 10, x-3=18 and add 3 so x=21 then since 2 is 8x you would multiply 8 by 21 which is 168.

The formula for circumfrence is C=pi x 2r or C= pi x r
In this case its C= 3.14 x 9 which is 28.26 rounded to 28.3
Answer:
Answer A is correct.
Step-by-step explanation:
Formula to find the circumference of a circle is :
C = π × d
Here,
d ⇒ diameter ⇒ 9m
First, let us find the circumference in terms of π.
C = π × d
= π × 9
= (9π)m
And now let us find the circumference to the nearest 10th.
Given that,
π = 3.14
Let us find now.
C = 9π m
= 9 × 3.14 m
= 28.26 m
≈ 28.3m

Each question is a division, and they want to know which mixed number is equivalent. I can help.
Answer:
28 ÷ 20 = 1.4 [tex]1\frac{2}{5} = \frac{7}{5} = 1.4[/tex]
18 ÷ 4 = 4.5 [tex]4\frac{1}{2}[/tex] [tex]= \frac{9}{2}[/tex] [tex]= 4.5[/tex]
9 ÷ 8 = 1.125 [tex]1\frac{1}{8}[/tex] [tex]= \frac{9}{8}[/tex] [tex]= 1.125[/tex]
11 ÷ 6 = 1.8333... [tex]1\frac{5}{6}[/tex] [tex]= \frac{11}{6} = 1.8333...[/tex]
12 ÷ 17 = 0.70588235 [tex]\frac{12}{17} = 0.70588235[/tex]
Steps:
1. In order to find your equivalent fraction you need to divide your equations. The dividing goes for the fractions too.
2. If you don't know how to divide mixed numbers I can show you one of the fractions.
Example:
4[tex]\frac{1}{2}[/tex]
multiply 4 x 2 4 x 2 = 8 add 8 + 1 8 + 1 = 9 convert into improper fraction [tex]\frac{9}{2}[/tex] denominator always stays the same. divide [tex]\frac{9}{2}[/tex] [tex]\frac{9}{2} = 4.5[/tex]3. now after dividing your fraction and equation it should turn out as a decimal.
4. check if the equation has the same decimal if they do they're equivalent.
I hope this helped you have a great day
The area of a circle is approximately 28.27 square feet. What is the length of the diameter?

Answer:
-1/3
Step-by-step explanation:
Answer:
-0.33
Step-by-step explanation:
The slope is -0.33 bc first, the line is going down so its negative. Second, use rise/run which is the Hight from each point / the length from each of the points. you can see that the rise is one, and the run is three so do 1/3 which equals -0.33

easy question: A train travels 30 miles in 1/3 of an hour. Whats is the trains average speed
Answer:
90 MPH
30 / (1/3) = 90
Answer:
90mph
Step-by-step explanation;
if an object travels 30 miles in the first part of an hour, and the speed is constant, then we can assume 30*3=90
in the first third, it went 30 mi, in the second it went 30mi, and in the last part it went 30 mi
30+30+30=90
or you could do 30* the denominator (in this case its 3), so 30*3=90

find the LCM of 8 and 9
Hey there!
Answer:
LCM = 72
Solution by Division Method
Write your numbers in the top row.
Divide your numbers by prime numbers as long as at least one of your numbers is evenly divisible by a prime number.
Division Table
2 |8|9
2 |4|9
2 |2|9
3. |1 |9
3 |1|3
| 1 |1
Bring down any numbers that are not evenly divisible by the prime number.
When the last row of results is all 1's you are done.
Find the product of the prime numbers in the first column to get the LCM:
LCM = 2 x 2 x 2 x 3 x 3
LCM = 72
Therefore,
LCM(8, 9) = 72
The volume of this right prism is 240.5 ft³.
What is the height, x, of the prism?
Enter your answer as a decimal in the box.
x = (Answer) ft
Answer:
x = 7.4 ft.
Step-by-step explanation:
Find the area of the base (32.5ft^2) and divide the area by that to find the height (240.5/32.5= 7.4ft)
The height of the prism is 7.4 feet.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given is a right trapezoidal prism.
Area of the prism = Base area × Height of the prism
Base is trapezoid.
Base area = [tex]\frac{1}{2}[/tex] (8 + 5) 5
= 32.5 feet²
Height of the prism = Length between the bases = x feet
So we have,
32.5 x = 240.5
x = 240.5 / 32.5
x = 7.4 feet
Hence the height of the prism is 7.4 feet.
