1. Simplify. 9 qt 9 pt?

Question

2.Choose the most reasonable measure. The thickness of a piece of cardboard. 0.3cm, 0.03km, or 3cm
3. Complete the statement, using a metric unit of weight.
A television weighs 30 ________.
4. Identify the rate in the following statement: 27% of 500 is 135
5. Is the following set of numbers a perfect triple? 13, 15, 18

Answer 1

1. 9qt / 9pt 4 quarts in a gallon, 1 quart is 2 pints,

So 9 qt is 1 gallon, 1 quart
9 pts is 1 gallon, 1 pint

So you have: 2 gals, 1 quart, 1 pint

Or, as a decimal: 3.375 gallons

2) .3cm

3) A television weighs 30 kgs

4) The rate is 27%

5) Yes. 13^2 + 15^2 = 18^2

Answer 2

remember that: sin²(x) + cos²(x) = one million by factoring the GCF of the expression, we've: one million/9 * (one million - 2sin²(x) + sin^4(x)) Then, by suitable sq. trinomial: ==> one million/9 (one million - 2sin²(x) + (sin²(x))²) ==> one million/9 (one million - sin²(x))² ultimately, rework one million - sin²(x) into cos²(x). for this reason, we acquire: ==> one million/9 * (cos²(x))² ==> cos^4(x)/9 i'm hoping this facilitates!
