The length of a rectangle is 5 more than 4 times its width. The perimeter is 90 meters. Find the dimensions of the rectangle.

So the width is 8 and the length is 37 :)

Step-by-step explanation:

Let's call the width "x." The length is then 5 + 4x

The perimeter, which is 90, is calculated by 2(length + width)

In our case, 90 = 2(x + 5 + 4x)

90 = 2(5x + 5)

90 = 10x + 10

80 = 10x

x = 8

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
