A box of donuts would cost: b = 3.84 + 0.18f
First, we have to find the total cost of the donuts.
12 x 0.32 = 3.84
Next, we need to determine the cost of the box. However, we don't know the surface area, just the cost per foot. We can multiply the number of square feet of the box by $0.18 to find the cost.
So our equation could be: b = 3.84 + 0.18f (where f is the surface area of the box in square feet)
Answer:

Step-by-step explanation:

Taking square root both sides, we get

Therefore, the values of
are:

Answer:
11. a)50 12. a)40
Step-by-step explanation:
sum of all three angles of trinagle=180
so
111.
80+50+x=180
130+x=180
x=180-130
x=50
12.
60+90+x=180
150+x=180
x=190-150
x=40
Answer:
which class of question is this
Answer:
7x+ 5y <= 10
Step-by-step explanation:
As the x represents the number of pounds of almonds and the price of the almonds is $7/lb, we need to look for an inequality where the x is multiplied by $7 and the same with the y and $5.
It's useless to multiply the x by $5 or the y by $7 because we are mixing the prices of the nuts.
On the other hand, we don't want to spend more than 10. That means we can spend 10 or less.
Therefore, the inequality we can use to find how much of each type of nut we can buy without spending more than $10 is
7x+ 5y <= 10
