A baby weighed 3.2 kg at birth. She gained 0.17 kg per week. She now weighs 5.75 kg. How old is she now?

Answers

5.75 (weight now) - 3.2 (weight at birth) = 2.55 (how much weight she has gained)

2.55 (how much weight she has gained) / 0.17 (weight gained per week) = 15 weeks

The baby is 15 weeks old.

the perimeter of the rectangle is 86 inches. if the length is 3 inches longer that the width, find the width of a rectangle.

Answers

Answer:

Width = 20 inches

Step-by-step explanation:

Perimeter = 86 inches

Width = W

Length = 3 + W

Use the formula 2L + 2W = P to solve

Substitute new value for length (3 + w) into the formula

2(3 + W) + 2W = P

Change perimeter into the equation to 86 inches (Given)

2(3 + W) + 2W = 86

Multiply

6 + 2W + 2W = 86

Add the W's

6 + 4W = 86

Subtract 6 from both sides of the equation

4W = 80

Divide both sides of the equation by 4

W = 20 inches

Hope this helps :)

The length is 23in and the width is 20 inches

The city of Houston, Texas typically has 90 clear days out of the 365 days in a year. Houston's clear days represent what fraction of a year? Write your answer in simplest form.

Answers

(90/365)=(18/73)

5 goes into both 90 and 365 evenly: (90/5)=18 & (365/5)=73
There are no other numbers that go into both 18 and 73 evenly.

Final answer:

90 clear days out of 365 days a year in Houston, Texas represents the fraction 18/73 of a year.

Explanation:

The city of Houston, Texas typically has 90 clear days out of approximately 365 days in 1 year. To answer this mathematics problem, we need to determine the fraction that represents Houston's clear days in a year. The fraction would be the number of clear days divided by the total number of days in a year, that is, 90/365. This fractions needs to be simplified to its simplest form. The greatest common divisor of 90 and 365 is 5. So divide both the numerator (90) and the denominator (365) by 5. This gives us 18/73. Therefore, the clear days in Houston represent 18/73 of a year.
