Solve for x.<br> 7 inches<br> Х<br> 11 inches

jonny [76]

Answer:

8.49 inches

Step-by-step explanation:

x^2 + 7^2 = 11^2

x^2 + 49 = 121

X^2 = 121 - 49

x^2 = 72 (then take square root on both sides)

x = 8.49 inches

The California Tiger Salamander is an endangered species, which decreases at the rate of 4.6% per year in a habitat that current

stellarik [79]

Answer:

Population after 4 years = 49 (nearest unit)

Population after 5 years = 47 (nearest unit)

Step-by-step explanation:

Yearly decrease = 4.6%

Decrease factor (what's left) = (100-4.6)% = 0.954

Current population, P = 60

population after n years = P(0.954)^n (to the nearest unit)

Population after 4 years = 60(0.954)^4 = 49.7 = 49 (nearest unit)

Population after 5 years = 60(0.954)^5 = 47.4 = 47 (nearest unit)

A circle with radius 3 has a sector with a central angle of 1/9 pi radians

marissa [1.9K]

Complete question:

A circle with radius 3 has a sector with a central angle of 1/9 pi radians

what is the area of the sector?

Answer:

The area of the sector = $\frac{\pi}{2}$ square units

Step-by-step explanation:

To find the area of the sector of a circle, let's use the formula:

$A = \frac{1}{2} r^2 \theta$

Where, A = area

r = radius = 3

$\theta = \frac{1}{9}\pi$

Substituting values in the formula, we have:

$A = \frac{1}{2}*3^2* \frac{1}{9}\pi$

$A = \frac{1}{2}*9* \frac{1}{9}\pi$

$A = 4.5 * \frac{1}{9}\pi$

$A = \frac{\pi}{2}$

The area of the sector = $\frac{\pi}{2}$ square units
