For the right triangle shown, the lengths of two sides are given. find the third side. leave your answer in simplified, radical
lisov135 [29]
If c is the hypotenuse and b is the leg, then the third side (a):
a= \sqrt{c^2-b^2}= \sqrt{16^2-9^2}= \sqrt{256-81}= \sqrt{175}=5 \sqrt{7}

If b and с are legs, then hypotenuse (a):
a= \sqrt{b^2+c^2}= \sqrt{9^2+16^2}= \sqrt{81+256}= \sqrt{337}

Rafael races his bicycle for
pychu [463]
Distance traveled = 70 m
Number of rotations = 29

We know, Circumference * Number of rotations = Distance traveled
So, C = 70 / 29
C = 2.41 m

Now, we know, diameter = C / π
So, d = 2.41/3.14 = 0.768

In short, Your Answer would be: 0.8 m

Hope this helps!

Given the area of circular base and the area of curved surface of the cone are 98.56 cm² and 264 cm² respectively. Find the heig
____ [38]

Answer: height = 13.9 cm

Step-by-step explanation:

The base area of a cone is the area of a circle. Given that base area = 98.56 cm^2

Base area = πr^2

Substitutes the value into the formula

98.56 = 22/7 × r^2

Cross multiply

689.92 = 22r^2

r^2 = 689.92/22

r = sqrt ( 31.36 )

r = 5.6 cm

Also, the curved surface area of a cone is πrL

Where the given value is 264 cm^2

Substitutes the value into the formula

264 = 22/7 × 5.6 × L

Where L = slant height

Cross multiply

123.2L = 1848

L = 1848 /123.2

L = 15 cm.

Using pythagorean theorem to find the height H of the cone.

H^2 = L^2 - r^2

H^2 = 15^2 - 5.6^2

H = sqrt( 193.64 )

H = 13.9 cm

You work at Initech for a year. Your annual salary income is $38,000. You received a 3% salary increase. What is your NEW salary
sdas [7]

$49,400. If you multiply the income (38,000) by the salary increase (3%=0.3), then you get 49,400. Good Luck!

I just need these three questions fine, they should be easy, 7th grade level
muminat

1) A graph is linear when the line on a graph is a straight line with no curves.

2) A proportional graph means that as x increases, y increases and when x decreases, y decreases and their ratio always stays the same.

3) (I don't know what type of equation you mean but this is my guess)

Division is the last step of an equation.
