The triangle that has side lengths of 7, 10, and 12 is not a right triangle. The correct answer is B. No.
The reason for this can be found in the Pythagorean theorem, which is a2 + b2 = c2 (this number 2 means square)
So, let's test this.
7*7 + 10*10 = 12*12
49+100 = 144
149 = 144
Since this is not equal, this isn't a right triangle.

Answer:
See below
Step-by-step explanation:
a) 47/100
b) .4777777..... =x
then 10x = 4.77777....
100x = 47.777777 .... now subtract 10x to get
90x = 43
x = 43/90
c) .4747474747...... = x
100x = 47.474747 now subtract x to get
99x = 47
x = 47/99
Points are (T,S) = (time, pounds), so you have (3.5, 605) and (10, 2100). Slope is (2100-605) / (10-3.5) = 1495/6.5 = 230. T is the independent variable (like x normally is in linear equations), so that narrows it down to choice A or choice D due to the slope. You can solve for b in y=mx+b or S = mT + b by plugging in one of the points: 2100 = 230(10) + b ===> b = -200. Therefore S = 230T - 200; S(12) = 230*12 - 200 = 2560 lbs [B]
<span>2) (a) Plug in 10 for x </span>
<span>(b) 10000 = 298.94x + 3215.48 </span>
<span>6784.52 = 298.94x </span>
<span>x = 6784.52/298.94 = 22.7 ===> in year 2023</span>
A cube is a 3 dimensional object with 6 square faces. All its sides are the same length, there fore the volume is equal to
where s is the side length.
To solve for s, take the cube root of both sides.
