Answer:
The answers to each part are:
Part A.
- <u>The quantity of apples is one-third of the quantity of grapes</u>.
Part B.
- <u>The quantity of apples is a quarter of the quantity of strawberries</u>.
Part C.
- <u>The number of cherries is two-elevenths of the total fruit</u>.
Step-by-step explanation:
To identify the answer in each case, you must remember that all the parts are equal, then:
Part A.
The parts of apples are 1 and the parts grapes are 3, so if you divide the first quantity with the second quantity you obtain:
So, <u>the quantity of apples is one-third of the quantity of grapes</u> or the quantity of apples is three times smaller than the quantity of grapes.
Part B.
The parts of apples are 1 and the parts of strawberries are 4, then you must divide the first quantity with the second quantity:
In this case, <u>the quantity of apples is a quarter of the quantity of strawberries</u> or the quantity of apples is four times smaller than the quantity of strawberries.
Part C.
First, you must add all the part of fruit:
- <em>1 part apple</em>
- <em>1 part orange</em>
- <em>4 parts strawberry</em>
- <em>2 parts cherry </em>
- <em>3 parts grape</em>
The total of fruits is 11 parts, taking into account the quantity of cherries is 2, now you can divide the number of cherries with the total parts of fruit:
- 2 / 11 = 2/11 (two-elevenths)
Now, you can see <u>the number of cherries is two-elevenths of the total fruit</u>.
Answer:
The average speed of Marshall is 29.7 mph
Step-by-step explanation:
Given;
distance traveled to work, d₁ = 27 miles
distance traveled back home, d₂ = 27 miles
initial time taken, t₁ = 1 hour and 20 minutes
final time taken, t₂ = 29 minutes
Total distance traveled, d = d₁ + d₂ = 27 miles + 27 miles = 54 miles
Total time taken for the journey, t = t₁ + t₂ = 1 hour + ( 20 mins + 29 mins)
t = 1 hour + 49 mins = 1 hour + 0.817 hour = 1.817 hour
The average speed is given by;
v = total distance / total time
v = 54 miles / 1.817 hour
v = 29.7 mph
Therefore, the average speed of Marshall is 29.7 mph
divide both sides by 7 to get x alone
84/7 = 12
