Magazine Problem 4
Name all of the sets of numbers to which each real number belongs. Let \(\mathbf{N}=\) natural numbers, \(\mathbf{W}=\) whole numbers, \(\mathbf{Z}=\) integers, \(\mathbf{Q}=\) rational numbers, and I = irrational numbers. $$\sqrt{12}$$
Problem 4
If \(c\) is the measure of the hypotenuse, find each missing measure. Round to the nearest tenth, if necessary. $$a=?, b=24, c=25$$
Problem 5
Use a calculator to find each square root to the nearest tenth. \(-\sqrt{32}\)
Problem 6
Estimate each square root to the nearest integer. Do not use a calculator. $$\sqrt{66}$$
Problem 9
Find the distance between each pair of points. Round to the nearest tenth, if necessary. $$S(-9,0), T(6,-7)$$
Problem 9
Find each square root. $$\sqrt{16}$$
Problem 10
Find each square root. $$\sqrt{49}$$
Problem 10
Solve each equation. Round to the nearest tenth, if necessary. $$3 m^{2}=222$$
Problem 11
LANDSCAPING A sprinkler waters a circular area of the lawn as shown. The formula \(A=3.14 r^{2}\) measures the distance \(r\) the sprinkler shoots water within a circular area \(A .\) How far is the sprinkler shooting water if it waters an area of 572.6 square feet? Round to the nearest tenth. (figure can't copy)
Problem 12
Find each square root. $$-\sqrt{25}$$
