Turn 2 1/2 into an improper fraction by multiplying 2 by 2, then adding 1 to that number and using 2 as the new denominator. You get 5/2. Then make it the same denominator as the serving size by multiplying it by 2, or 2/1. You get 10/4. After that, see how many times 3 goes into 10. It’s 3, with 1 remaining. Therefore, he can make 3 1/4 servings, or 3, if you need an exact answer.
Answer:
-6
Step-by-step explanation:
f(x)=2x^2+5x-4
Let x= -2
f(-2)=2*(-2)^2+5(-2)-4
= 2 (4)+5(-2)-4
= 8 -10 -4
= -6
Answer:
y = 2/5x+1
Step-by-step explanation:
When you're translating up or down, the number goes all the way to the right. Because the graph was being translated down 4 already (-4), we add the 5 (up 5) to it. Therefore, -4 + 5 is 1.
Suppose we have a cylinder with radius r1 and height h1. The volume of this cyliner would be calculated as:
V1 = pi(r1^2)h1
If the measurements are being doubled then r2=2r1 and h2=2h1. The volume would change as follows:
V2 = pi(r2^2)h2
V2 = pi((2r1)^2)2h1
V2 = pi(4)(r1)^2)2h1
V2 =8 pi(r1)^2)h1
V2 = 8 V1
Answer:
C
Step-by-step explanation:
The inequality says greater than or equal to 8, which means the first two are automatically ruled out because they are both less than/equal to.
Then look at C and D, D starts at 3 and C starts at 8 so the answer should be C
