To solve this problem you must apply the proccedure shown below:

1- If the triangle is a rigth triangle, you must apply the Pythagorean Theorem. Taking the length 3 inches as the hypotenuse, which is the longest side of the triangle, you have:

a^2=b^2+c^2
c=√(a^2-b^2)

b=3/4 inches
a=3 inches

2- When you susbtitute the values, you obtain:

c=√(3 inches)^2-(3/4 inches)^2
c=2.90 inches

The answer is: 2.90 inches.

Find the sum of the equation

stealth61 [152]

Answer:

$\frac{{y}^{2}+13y-6}{{(y-1)}^{2}(y+7)}$

Step-by-step explanation:

1) Rewrite ${y}^{2}-2y+1y$ in the form ${a}^{2}-2ab+{b}^{2}$ , where a = y and b = 1.

$\frac{y}{{y}^{2}-2(y)(1)+{1}^{2}}+\frac{6}{{y}^{2}+6y-7}$

2) Use Square of Difference: ${(a-b)}^{2}={a}^{2}-2ab+{b}^{2}$ .

$\frac{y}{{(y-1)}^{2}}+\frac{6}{{y}^{2}+6y-7}$

3) Factor ${y}^{2}+6y-7$ .

1 - Ask: Which two numbers add up to 6 and multiply to -7?

-1 and 7

2 - Rewrite the expression using the above.

$(y-1)(y-7)$

Outcome/Result: $\frac{y}{(y-1)^2} +\frac{6}{(y-1)(y+7)}$

4) Rewrite the expression with a common denominator.

$\frac{y(y+7)+6(y-1)}{{(y-1)}^{2}(y+7)}$

5) Expand.

$\frac{{y}^{2}+7y+6y-6}{{(y-1)}^{2}(y+7)}$

6) Collect like terms.

$\frac{{y}^{2}+(7y+6y)-6}{{(y-1)}^{2}(y+7)}$

7) Simplify ${y}^{2}+(7y+6y)-6y$ to ${y}^{2}+13y-6y$

$\frac{{y}^{2}+13y-6}{{(y-1)}^{2}(y+7)}$

A 12 year old blinks about 150 times in 15 minutes. How many times does a 12 year old bink in 1 day?

shepuryov [24]

Answer:

14400 blinks per day

Step-by-step explanation:

We need to convert minutes to days

60 minutes = 1 hour

24 hours = 1 day

The units will cancel leaving blinks per day.

150 blinks 60 minutes 24 hour 216000

---------------- * ---------------------- * ------------ = --------------- blinks/day

15 minutes 1 hour 1 day 15

14400 blinks per day
