Number 21 is the first answer a.) 8
Answer:
The rate of decay is 0.08
Step-by-step explanation:
we have

Let
r-----> the rate of decay
we know that
In this problem

Solve for r

Let's solve your equation step-by-step.<span><span>
98−<span>x2</span></span>=0</span>
Step 1: Simplify both sides of the equation.<span><span><span>
−<span>x2</span></span>+98</span>=0</span>
Step 2: Subtract 98 from both sides.<span><span><span><span>
−<span>x2</span></span>+98</span>−98</span>=<span>0−98</span></span><span><span>
−<span>x2</span></span>=<span>−98</span></span>
Step 3: Divide both sides by -1.<span><span><span>
−<span>x^2/</span></span><span>1</span></span>=<span><span>−98/</span><span>1</span></span></span><span><span>
x^2</span>=98</span>
Step 4: Take square root.<span>
x=<span>±<span>√98</span></span></span><span><span>
x=<span><span><span>7<span>√2</span></span><span> or </span></span>x</span></span>=<span>−<span>7<span>√2</span></span></span></span>
Answer:<span><span>
x=<span><span><span>7<span>√2</span></span><span> or </span></span>x</span></span>=<span>−<span>7<span>√<span>2

Answer:
The length of the triangle is 3x given
The no of sides is 3x 3x 3x so 3x+3x+3x= 180
9x=180 x= 20
3x =3*20=60
3x=3*20=60
3x=3*20=60
Answer:
Hello there, the answer would be
Step-by-step explanation:
We cut the figure into two different shapes.
Since on one side it is 4 feet and the height is seven, we cut right there.
So the bottom figure is now 4 x 5 = 20
The top figure is cut with 3 height left, So all we do is just multiply.
8 x 3 = 24.
20+24=44.
