Let x = the amount of grapes that can be bought for 0.40.
Note: By 90 I assume you mean 90 cents. The same for 40.
12/x = 0.90/0.40
0.90x = 12(0.40)
0.90x = 4.80
x = 4.80 ÷ 0.90
x = 5.33333
We can round the decimal to the ones place to get 5 grapes.

Answer:
Hello! answer: 268 square meters
Step-by-step explanation:
To find the total surface area you find the area of each face then add them up so...
10 × 3 = 30
10 × 3 = 30
8 × 3 = 24
8 × 3 = 24
10 × 8 = 80
10 × 8 = 80
Now that I found the area for each face I will just add them up so...
30 + 30 + 24 + 24 + 80 + 80 = 268 therefore the area is 268 square meters Hope that helps!
The time it will take before Diego catches up with Linh will be after 8 hours
Let :
<u>Diego</u> :
- Travel speed = 75 mph
- Travel time = t
<u>Linh</u>:
- Travel speed = 60 mph
- Travel time = t + 2
Recall :
- Distance covered = speed × time
- Distance covered by Linh = 60(t + 2)
- Distance covered by Diego = 75t
<u>Time</u><u> when Diego catches up with Linh</u> :
Diego's distance = Linh's distance
75t = 60(t + 2)
Solve for t ;
75t = 60t + 120
Collect like terms
75t - 60t = 120
15t = 120
Divide both sides by 15 to isolate t
t = (120 / 15)
t = 8
Hence, Diego will catch up with Linh after 8 hours.
