Step-by-step explanation:

9\left(x-6\right)+41=75\\ x=\frac{88}{9}

Step 1: Subtract 41 from both sides

9\left(x-6\right)+41-41=75-41

9\left(x-6\right)=34

Step 2: Divide both sides by 9

\frac{9\left(x-6\right)}{9}=\frac{34}{9}

x-6=\frac{34}{9}

Step 3: Add 6 to both sides

x-6+6=\frac{34}{9}+6

x=\frac{88}{9}

In the triangle below, what is the length of the hypotenuse?
aliina [53]

Answer:

<h2>B. 6</h2>

Step-by-step explanation:

I'd like to begin by apologizing for the late reply.

PROCESS:

1) Begin by analyzing the triangle

2) Notice how you can take the sin of 30 to find the hypotenuse

3) sin30= 3/x

4) If you don't see how I did that, a fun trig word play for functions, is

S O/H

C A/H

T O/A

where

S= Sine

C= Cosine

T= Tangent

O= Opposite

H= Hypotenuse

A= Adjacent

so side opposite of 30 is side 3, and the hypotenuse is x.

5) sin30= 3/x = 6

6) Your answer, hypotenuse is 6

BONUS: If you want to find the base length, use Pythagorean theorem.

c=√a2+b2

b=√c2-a2= √6^2 - 3^2= 5.19 or 5.2

Sarah rides her horse for 2 1/6 hrs with a constant speed of 6 km/hr and then for another 2 hours and 5 minutes with a constant
yan [13]
We know that
speed=distance/time

1) <span>Sarah rides her horse for 2 1/6 hrs with a constant speed of 6 km/hr
time=2 1/6 hrs----> 13/6 hrs
speed=6 km/h
distance=speed*time----> 6*(13/6)---> 13 km

2)</span><span>for another 2 hours and 5 minutes with a constant speed of 12 km/hr
time=2hrs+5 minutes----> 2+(5/60)--> 125/60 hrs
speed=12 km/hrs
distance=speed*time----> 12*(125/60)---> 25 km

3) find the </span><span>average speed for the total trip
total distance=13 km+25 km----> 38 km
total time=(13/6)+(125/60)----> (10*13+125)/60----> 4.25 hours
speed=38/4.25----> 8.94 km/hrs

the answer is
8.94 km/hrs</span>

A 13 foot ladder is placed 5 feet away from my wall .The distance from the ground straight up to the top of the wall is 13 foot
zysi [14]

Answer:

  no

Step-by-step explanation:

Assuming the wall makes a 90-degree angle with the ground, the ladder is the hypotenuse of a right triangle whose legs are the ground distance, the wall height, and whose hypotenuse is the ladder length.

The hypotenuse of a right triangle must be longer than either side. If one side is length 13 and one side is length 5, the hypotenuse must be about 13.93. A 13-ft ladder will not do.
