Answer:
1. 3x + 6
2. 
or 7.071
3. 
Step-by-step explanation:
1. 3 consecutive even integers
If the first is x, the 2nd is x+2, and the 3rd is x+4
x + (x+2) + (x+4)
= 3x + 6
2. The equation for circumference is
If the diameter is 
The the radius is half of that.
So the circumference is
3. To divide we multiply by the reciprocal. So flip the fraction that we are dividing by.
Answer:
2n + n² -1
Step-by-step explanation:
2n + 2 + n² - 3
2n + n² -1
Lemme know if I read the equation wrong :)
Answer:
1/770
Step-by-step explanation:
7x10x11=770 he is sitting in one seat so 1/770 she will win.
4 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 4 4/4 = 5
6 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 6 6/4 = 7 1/2
7 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 7 7/4 = 8 3/4
8 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 8 8/4 = 10
The answer is C because 8 batches needs 10 cups of flour, and 7 batches is closest to 9 cups than 6 batches.
You can also look at it like this:
1 1/4c ≤ 9 (c is # of cups)
Or you could have multiplied 4, 6, 7, 8 to 1 1/4 or 1.25
Answer: Approximately 6573481.358 Hispanic businesses
Step-by-step explanation:
In 2009, the number of Hispanic owned businesses was 1.15 million
In 2013, the number of Hispanic owned businesses was 1.52 million
Since the growth is exponential, we would apply
Tt = ar^t-1
Where Tt is the number of Hispanic owned businesses after t years
a is the number of Hispanic owned businesses in 2009
r is the common ratio or exponential growth rate of the number of Hispanic owned business
at 2013 , t = 5(t= 0 in 2009 to t= 5 in 2013)
1520000 = 1150000 × r^5-1
1520000 / 1150000 = r^4
152/115 = r^4
1.32174 = r^4
Taking 4th root of both sides,
r = 1.07222
We want to determine the number of Hispanic owned business that would be there in 2034. It becomes
T2034 = 1150000 × 1.07222^25
T2034 = 1150000 × 5.7160
T2034 = 6573481.3579901
Approximately 6573481.358 Hispanic businesses
