Answer:
Step-by-step explanation:
1. Make 1 2/7 an improper fraction = 9/7
2. Multiply 7 on both numerator and denominator for 2/3 to make 14/21, and multiply 3 for both numerator and denominator for 9/7 to make 27/21.
3. Add them together. 14/21+27/21=41/21.
4. (Optional) If the question is asking for mixed numbers, 41/21 = 1 20/21.
Answer:diameter=9.92m
Step-by-step explanation:
Area=77.28
π=3.14
Area=π x (d/2)^2
77.28=3.14 x (d/2)^2
Divide both sides by 3.14
77.28/3.14=(3.14x(d/2)^2)/3.14
24.6=(d/2)^2
Take them square root of both sides we get
d/2=√(24.6)
d/2=4.96
d=4.96 x 2
d=9.92
There would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers
Answer:
<1 = 100
<2 = 80
Step-by-step explanation:
Angle 1 and angle 2 are supplementary
Supplementary angles add to 180 degrees
<1 + <2 = 180
The angles are in a ratio of 5 to 4
Multiply by x to get the measure of each angle
<1 = 5x <2 = 4x
5x+4x = 180
Combine like terms
9x = 180
Divide by 9
9x/9 =180/9
x =20
<1 = 5x = 5*20 = 100
<2 = 4x = 4*20 = 80
