Answer: The Ferris wheel’s speed in feet per hour.
Step-by-step explanation:
Answer:
i would say B is the answer
Step-by-step explanation:
Part A: About 0.21
We will put the wanted outcome (yellow pieces of candy) over the total number of possible outcomes (total pieces of candy).
About 0.21
Part B: About 50
First we will do the same as we did with the yellow pieces of candy, wanted outcomes over possible outcomes.
0.25
Now, we will multiply the total 200 pieces by 0.25 since 0.25 of them are estimated to be green.
200 * 0.25 = 50
I estimate about 50 of the pieces to be green.
Answer:
(x+1)(2x+5)
Step-by-step explanation:
f(x) = 2x² + 7x + 5
Factor the expression by grouping. First, the expression needs to be rewritten as 2x²+ax+bx+5. To find a and b, set up a system to be solved.
a+b=7
ab=2×5=10
Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 10.
1,10
2,5
Calculate the sum for each pair.
1+10=11
2+5=7
The solution is the pair that gives sum 7.
a=2
b=5
2x²+7x+5 as (2x²+2x)+(5x+5).
(2x²+2x)+(5x+5)
Factor out 2x in the first and 5 in the second group.
2x(x+1)+5(x+1)
Factor out common term x+1 by using distributive property.
(x+1)(2x+5)
