To find "s", you can use the Pythagorean theorem(which you can only use for right triangles):

a² + b² = c²               (c is the hypotenuse/the longest side of the triangle)


t = 18  (hypotenuse)

r = 12

s = ?

Plug in the numbers into the equation

a² + b² = c²

(12)² + b² = (18)²

144 + b² = 324        Subtract 144 on both sides

b² = 180           Square root both sides

b = √180  or  13.4

Marisol receives total employee benefits that are 14.5% of her gross annual pay. If Marisol has a gross annual pay of $50,000, h
JulijaS [17]
If you would like to know how much in total employee benefits does Marisol receive, you can calculate this using the following steps:

14.5% of $50,000 = 14.5% * 50,000 = 14.5/100 * 50,000 = $7,250

The correct result would be c. $7,250.

Rewrite the following multiplication problem using the associative property and then show that both results will be the same.
densk [106]

<u>Answer:</u>

The answer is the same i. e., 4.375 in all the cases as shown below.

<u>Step-by-step explanation:</u>

\frac {3}{7} \times \frac {5}{6} \times \frac {1}{4}

= \frac {35}{8}

= \frac {3}{7} \times \frac {1}{4} \times \frac {5}{6}

= \frac {5}{6} \times \frac {1}{4} \times \frac {3}{7}

= \frac {5}{6} \times \frac {3}{7} \times \frac {1}{4}

= \frac {1}{4} \times \frac {5}{6} \times \frac {3}{7}

= \frac {1}{4} \times \frac {3}{7} \times {5}{6}

= 4.375 (answer)

Find the slope of the line containing the points (1, 4) and (3, 7).
irina1246 [14]

Answer: 3/2

Step-by-step explanation:

the formula to find slope is:

m = rise/run = \frac{y2-y1}{x2-x1}

In this case:

m = 3/2 = \frac{7-4}{3-1}

Help me with (-6,-7);y=-4x+1
Morgarella [4.7K]

Answer: y=-4x-31

Step-by-step explanation:

To find a ling that is parallel to the given line and passes through the given point, we need to use the given point. We know that the slope MUST stay the same because parallel lines NEVER touch. All we have to do is plug in the point and find the y-intercept.

-7=-4(-6)+b            [multiply]

-7=24+b                 [subtract both sides by 24]

b=-31

Now, we know that y=-4x-31 is the equation.

The equation for the circle below is the x2 + y2=81. what is the length of the circles radius
larisa [96]

Answer:

9

Step-by-step explanation:

Compare your x2 + y2=81 to the following:

                       x^2 + y^2 = 81

The " ^ " symbol indicates exponentiation.

Now compare  x^2 + y^2 = 81 to

                         x^2 + y^2 = r^2.  

This is the standard equation of a circle of radius r centered at the origin, (0,0).  You can see for yourself that 81 must equal r^2.


Taking the square root of 81, we get plus or minus 9.

But the radius must be positive, so we reject the -9 and take +9.

The radius is 9.
