First find the formula which is A(N)=A+(N-1)D then fill in what you know
N=term your looking for
A=first term
D= common diffrence

Once filled in you will get this 18(18)=18+(18-1)-6
then solve to get 324= -84

Your final answer is that the 18th term is -84

Write and solve the system of linear equations described by the application and then answer the question. One hundred sixty feet

Lena [83]

Answer:

80 ft x 40 ft

Step-by-step explanation:

Let 'L' be the length of the longer side and 'W' be the length of the shorter side (or the width).

The equations that compose the linear system are:

$L+2W=160\\L=2W$

Solving the system:

$L+L=160\\L=80\\W=\frac{L}{2}\\W=40$

The garden is a rectangle with dimensions 80 ft x 40 ft.

AURORKA [14]

ratio of the diagonal to the side of the rectangle is 17/8 or 17:8

Step-by-step explanation:

Length of Diagonal = 34 inches

Length of side = 16 inches

Base= 30 inches

We need to find the ratio of the diagonal to the side of the rectangle.

ratio of the diagonal to the side of the rectangle = $\frac{length of diagonal}{length of side}$

Putting values:

$Ratio=\frac{34}{16} \\Simplifying:\\Ratio=\frac{17}{8}$

So, ratio of the diagonal to the side of the rectangle is 17/8 or 17:8

lord [1]

Answer:

the 90th percentile is 145

Step-by-step explanation:

Data provided:

152 121 130 143 122 101 137 98 138 127 145 117

Number of students considered, n = 12

To find:

90th percentile

Now,

Step 1 : Arrange the data in ascending order

98, 101, 117, 121, 122, 127, 130, 137, 138, 143, 145, 152

Step 2 : Compute the position of the 90th percentile

position of the 90th percentile, i = (90% × n)

Thus,

i = 0.90 × 12

i = 10.8

Now,

Step 3 : Since, the index i is not an integer, round up to the nearest integer

i.e i = 11

Therefore,

The 90th percentile is the value in 11th position,

i.e 145
