Answer: 40 kilometers
Step-by-step explanation: Since the word ratio is cm/km (centimeter/kilometer), and the number ratio is 2/5, you will have to create another set and put the 16 cm next to the 2 cm. So it would be 2/5=16/X. Now you have to find the value of x. First, you have to multiply 5 by 16, which is equal to 80. Now you divide it by 2 and you will get 40 kilometers as your final answer.
Answer:
13 ft
Step-by-step explanation:
(Given)
(Given)
- Perpendicular dropped from the center of the circle to the chord bisects the chord.
- Let the
be r ft.
- Radius of the circle, perpendicular to the chord and half of chord forms a right triangle where r represents the hypotenuse. Thus, by Pythagoras Theorem:
Answer:
6.0 hours
Step-by-step explanation:
1 hour is the same as 60 minutes.
"Mary peels 8 oranges in 10 minutes"
1 hour = 60 minutes = 6 * 10 minutes
In 1 hour, she peels 6 times as many oranges, so Mary peels 48 oranges in 1 hour.
"Jane peels 3 oranges in 5 minutes"
1 hour = 60 minutes = 12 * 5 minutes
In 1 hour, she peels 12 times as many oranges, so Jane peels 36 oranges in 1 hour.
Combined, the peel 48 + 36 = 84 oranges in 1 hour.
(500 oranges)/(84 oranges/hour) = 5.952 hours
Answer: 6.0 hours
Answer:
21 + 7b
Step-by-step explanation:
We have the expression 7(3 + b) and are being asked the answer.
Our expression has a number out of a certain parenthesis, when this occurs, this means that we must distribute the number outside the parenthesis to the numbers inside. Do as following :
7(3 + b)
(7(3) + 7(b))
21 + 7b
(I am unsure on whether you forgot the "= 0" at the end, if you did please tell me in the comment section and I will change my answer.)
