Answer:
They will need between 2520 to 2680 pounds of cookie dough.
Step-by-step explanation:
In order to figure out how many pounds of cookie dough the math club will need, we first need to know how many pounds of dough are sold per person.
Last year, the club sold 2,080 pounds of cookie dough to 520 people, this means the amount sold to per person is:
Thus for 630 people the amount of dough needed is
and for 670 people
Thus the amount of dough the club will need is between 2520 to 2680 pounds.
23. because there is a 90 degree angle and then the 67 degree angle, and triangle law says that all angles add up to 180.
Answer:
20
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x) = 3x² - 2 + 4x + 2 = 3x² + 4x
Substitute x = 2 into f(x) + g(x)
(f + g)(2) = 3(2)² + 4(2) = (3 × 4) + 8 = 12 + 8 = 20
Answer:
A
Step-by-step explanation:
Cosine is the ratio of "adjacent" to "hypotenuse"
With respect to the Angle E, the adjacent side is FE and the hypotenuse (always opposite side to 90 degree angle) is DE.
We are given DE = 26, but we need FE. We will solve for FE using Pythagorean Theorem, which tells us:
leg^2 + another leg^2 = hypotenuse^2
So, we will have:
10^2 + FE^2 = 26^2
Now, we solve for FE:
So,
Cos(E) = adj/hyp = 24/26
Correct answer is A
