Find the length of side AB in the right triangle shown.

Bogdan [553]

Side AB is 72 cm long.

Explanation:

To find the length of side AB you have to use this formula:

${a}^{2} + {b}^{2} = {c}^{2}$

*Remember there are two legs (a and b) and a hypotenuse (c) on a triangle. The longest side will be the hypotenuse and the other two will be the legs. For this triangle the hypotenuse is side BC while the legs are sides CA and side AB.

Plug in the numbers into the equation.

${65}^{2} + {b}^{2} = {97}^{2}$
For this triangle, you were given the hypotenuse (c) and one leg (a). To find the last length solve the equation and balance it so only b is left, like this:

$4225 + {b}^{2} = 9409$

$9409 - 4225 = 5184$

Soo...

${b}^{2} = 5184$

Then to get the side length, square root 5184.

$\sqrt{5184} = 72$

So the length of the last side is 72 cm.

pentagon [3]

Answer:

x= -2 and x = 6

Step-by-step explanation:

The solutions are where the two graphs intersect

x=6, y= 10 is one point

x=-2 and y = -6 is the other point

There's no need to get into an ethical morass over math homework.

M is 20% less than N means

M is 100-20=80% of N

M=0.80 N

M/N = 0.8 = 4/5

Ratio: 4/5

When we know a, the average, and n, how many numbers there are, we know the sum s, because a=s/n so s=na.

So the sum of our six numbers is 6(3.5)=21 so the sum of the seven numbers is 21+4.2=25.2 so the average is 25.2/7 = 3.6

Answer: 3.6

|2p + 4 | < 3

At p=-2 the absolute value is zero. As p gets more negative the absolute value argument (inside part) gets negative and the absolute value gets bigger, more positive. Eventually the inside will be exactly -3, when

2p +4 = -3

2p = -7

p = -7/2 = -3 1/2

So p=-4 will make the inequality false, and p=-3 is the smallest integer that makes the inequality true.

Answer: -3

A car rental agency advertised renting a car for $26.95 per day and $0.27 per mile. If David rents this car for 3 days, how many

Lapatulllka [165]

Step-by-step explanation:

1 day = $ 26.95

3 days = 26.95 × 3

= $80.85

Remainder = $100 - $80.85

= $19.15

1 mile = $ 0.27

= $19.15 ÷ $0.27

= 71 miles
