Answer:

8 3/4 cups of sugar

Step-by-step explanation:

1 batch of chocolate chip cookies ↔ 2 1/2 cups of sugar

3 1/2 batch of chocolate chip cookies ↔ 3 1/2 * 2 1/2 cups of sugar

3 1/2 * 2 1/2 = 7/2 * 5/2 = 35/4 = 8 3/4 = 8.75

Tony bowled 135 and 145 in his first two games. write and solve a compound inequality to find the possible values for a third ga
stira [4]
The average has to be at least 120 and at most 130
To calculate the average we need the sum of all values divided by the number of values, in this case, three (135, 145 and the third result).
120 ≤ (135 + 145 + n)/3 ≤ 130

In inequalities like this, what we change in one side, must be changed in the othe rside as well.
360 ≤ 280 + n ≤ 390
80 ≤ n ≤ 110

Law of cosines: a2 = b2 + c2 – 2bccos(A) What is the value of n to the nearest whole number? 18 22 29 41
nalin [4]
We know that
applying the law of cosines
a² = b²+ c²<span> – 2*b*c*cos(A)
</span>
in this problem
a=?
b=20
c=9
A=90°
so
a² = b²+ c² – 2*b*c*cos(A)
but
cos (A)=0
a² = b²+ c²-----> 20²+9²----> a²=400+81----> a²=481-----> a=√481
a=21.93-----> a=22

the answer is
22
