y

using the ' law of exponents '

a^ m/a^ n = a^ (m - n)

so y^ 9/y^ 8 = y^ (9-8) = y^1 = y

Simon's dog jumped into a stream at a 68° angle from the corner of a bridge. simon crossed the bridge and walked downstream to m
artcher [175]

The length of the bridge is 12.12 feet.

The length the dog swam is 32.36 feet.

The situation forms a right angle triangle.

<h3>What is a right angle triangle?</h3>

A right angle triangle has one of its angles as 90 degrees. Therefore, the sides and angle can be found using trigonometric ratios.

The length of the bridge is the opposite side of the triangle and the length the dog swim is the hypotenuse side of the triangle.

Therefore,

Let's find the length of the bridge as follows:

tan 68° = opposite / adjacent

tan 68° = 30 / l

cross multiply

l = 30 / tan 68

l = 12.1212121212

length of the bridge = 12.12 ft

The length the dog swim is as follows:

sin 68°= opposite / hypotenuse

sin 68° = 30 / h

h = 30 / sin 68

h = 32.3561767942

The distance the dog swimmed = 32.36 ft

A combination lock has numbers 0-49 on it. How many different 3-digit lock
Harman [31]

Answer:

19,600

Step-by-step explanation:

0-49=50 numbers

n=50

r=3

C(n,r)=n!/(r!(n-r)!)

=50!/(47!)(3!)

C(n,r)=C(50,3)

=50!/(3!(50−3)!)

= 19600

Adding or subtracting fractions with different denominators
Bas_tet [7]

Step-by-step explanation: You can't continue on with the problem until the denominators are the same. So you need to find the LCD (Least Common Denominator). For example...

\frac{1}{2} +\frac{1}{3}  The LCD is six

\frac{1*3}{2*3}=\frac{3}{6} =\frac{1}{3}

\frac{1}{2}+ \frac{1}{3}= \frac{3}{6} +\frac{2}{6}

\frac{3+2}{6}= \frac{5}{6}

Hope this helps, have a BLESSED and wonderful day! :-)
