Answer:
A. 2/20
Step-by-step explanation:
2/20 = 1/10
2/15 = 2/15
2/10 = 1/5
Answer:
6x^2 + 8x + 28
Step-by-step explanation:
2 times the length plus 2 times the width gives the perimeter
2(3x^2 + 3x + 6) + 2(x + 8)
6x^2 + 6x + 12 + 2x + 16
6x^2 + 8x + 28
Cosα=adjacent/hypotenuse
In this case you have:
cosα=FE/DF
DF=FE/cosα, we are told that FE=13 and α=34 so
DF=13/cos34
DF≈15.68 which is
DF≈15.7 (to nearest tenth)
Next term = 10
You add 3 to each term to get the next
1+3 = 4
4+3 = 7
7+3 = 10
etc etc
The domain of the sequence is 1,2,3,4,... basically the set of positive whole numbers. This is known as the set of natural numbers or counting numbers. We don't include 0. The domain is the set of possible inputs for 'n' in the formula mentioned below.
The range is the sequence of values shown.
The formula to generate the sequence is
an = 3n-2
as shown by these steps below
an = a1 + d(n-1)
an = 1 + 3(n-1)
an = 1+3n-3
an = 3n-2
To get any term you want, plug in a whole number for n. For example, plug in n = 4 to get...
an = 3n-2
a4 = 3*4-2
a4 = 12-2
a4 = 10
Showing that the fourth term is 10 as found earlier above.
Answer: 110
Step-by-step explanation:
Given;
Total cost C = $151
Enrollment fee E = $30
Charge per 10 test t = $11
n is the number of packet of test taken.
The questions can be represented by the equation below;
30 + 11n = 151
Substracting 30 from both sides.
11n = 151-30 = 121
n = 121/11
n = 11
Since the number of packet of test is 11 and each packet contains 10 tests. The number of test N is given by;
N = 10 n = 10 ×11 = 110
N = 110
