</span>5/8 square foot in ¼ hour. Find the unit rate.
Since the given numbers are fraction, let’s convert these into decimals to be
able to get the correct unit rate.
=> 5/8 = 0.625 or 0.63 square foot.
=> ¼ = 0.25 hour or 15 minutes.
=> 0.625
now, let’s show the unit rate of 5/8 square foot in ¼ hour.
=> 0.63 square feet / 15 minutes
Divide the square feet value by 15
=> 0.042 square feet / minute</span>
So basically you want to find the total percentage of cakes that weren't sponge cakes first.
You already have the 50% of party cakes. For the 1/5 percent of fruit cakes, you can multiply it by 20/20, to get 20/100, and then just take the 20 to get 20% that were fruit cakes.
Now you can just add the percentages together.
50% + 20% = 70%
So now you know 70% weren't sponge cakes, out of 100%.
So here you can just subtract 70% from 100% to figure out the remaining part of 100%, which must be sponge cakes.
100% - 70% = 30%
So 30% of the cakes were sponge cakes.
If you’re trying to find f(-1) it would be -20

Answer:
6 cups of flour
Step-by-step explanation:
we know that
the ratio of the recipe=(1 1/2)/(3/4)
1 1/2=1.5 cups of flour
3/4 stick of butter-------> 0.75 stick of butter
by proportion
1.5/0.75=x/3---------> 3*1.5=0.75*x
x=3*1.5/0.75----------> x=6 cups of flour
