Answer:
13
Step-by-step explanation:
144 = pie radio square
144 divided by pie = 45.83662361
45.83662361 square root = 6.770275003
6.770275003 multiply by 2 = 13.54055001
13.54055001 = diameter
Answer:
y=7600(5^(t/22))
Step-by-step explanation:
This is going to be an exponential function as it grows rapidly.
This type of question can be solved using the formula y=a(r^x), where a is the inital amount, r the factor by which the amount increases and x is the unit of time after which the amount increases.
x=t/22
a=7600
r=5
∴y=7600(5^(t/22))
Answer:20
Step-by-step explanation:
25% is 1/4 so multiply 5 times 4
Answer:
7
Step-by-step explanation:
You can estimate the number as being ...
(100 -50)/7 = 50/7 = 7 r 1
That is, there are likely to be 7 multiples of 7 between 50 and 100. This is a small enough number of them that we can count them:
56, 63, 70, 77, 84, 91, 98 . . . . 7 multiples of 7
_____
In general, you want to make sure that you don't overlook one at the beginning or end of the range. One way to ensure that you get a correct count is to write an equation for the n-th multiple of 7 in the range. Here, that would be 49+7n. We would want to find n such that ...
49 +7n ≤ 100
7n ≤ 51
n ≤ 51/7 = 7 2/7
The largest integer n less than 7 2/7 is 7, so there are 7 multiples of 7 between 50 and 100.
Answer:
Region 1 : 3
Region 2: 2
Step-by-step explanation:
Given the inequalities :
2x - 1 > 3 and 3(x-3)<0
To obtain a value inneachbregionwhicj makes the inequality or inequalities true, we solve for x
Inequality 1 :
2x - 1 > 3
Add 1 to both sides
2x - 1 + 1 > 3 + 1
2x > 4
Divide both sides by 2
2x/2 > 4/2
x > 2
(3, 4,..)
Inequality 2:
3(x-3)<0
3x - 9 < 0
Add 9 to both sides
3x - 9 + 9 < 0 + 9
3x < 9
Divide both sides by 3
3x/3 < 9/3
x < 3
