Answer:
Grandma baked 72 cakes
Step-by-step explanation:
Let x=biscuits cake baked by grandma
1/4x=chocolate
1/3x=nuts
1/4+1/3=3+4/12
=7/12x
Remaining
X-7/12x
=12-7x/12
=5/12x
1/2 of 5/12x=fruit
5/24x =fruit
Remaining
5/12x-5/24x=15
10-5/24x=15
5/24x=15
x=15÷5/24
=15*24/5
=360/5
=72
x=72 cakes

You have to change the variable, u=3x and from this can derivate u and get du=3, so the derivate for e^u is u'*e^u so the answers is 3e^3x
Answer:
20:100
Step-by-step explanation:
We know that percentages are out of 100. The rose garden is 20 percent of the garden. Which is 20 percent/100 percent. A ratio says how much of one thing there is compared to another thing. Therefore we are comparing 20:100. You can also simplify this ratio to 1:5
