Answer:
<h2>18mins</h2>
Step-by-step explanation:
This problem is on combined work rate
given that
Marta can vacuum the house in 30 min
then her rate= 1/30
Also, her daughter will take 45 min to vacuum the house
her daughter's rate will be = 1/45
then the combined work rate is
1/30+1/45=1/T
30+45/30*45=1/T
75/1350= 1/T
1/18=1/T
This means that they will both take 18 minutes working together to vacum a house

Answer:
The answer is A (Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit rate)
Step-by-step explanation:
Because the proportional relation is defined by k = 
. If ratio is 
then it is a rate. Unit rate means per 1 unit such as 
or 
thus the correct answer is A.
Okay so i am no math genius but i did it like this, 30 strawberries and 50 grapes would be 80 fruits. say all 5 people got an equal amount so 80/5=16. so 16 pieces would be 8 each so 8 strawberries(sb) and 8 grapes(g). sb= 6 calories and g=3 calories. 48 calories for sb and 24 for g. 72 calories each. unless i did this totally wrong
