Use the Pythagorean theorem to solve this problem. So, 81+x^2=1681. ( Pythagorean theorem: a^2+b^2=c^2). x^2=1600. x=40.
Answer:
0.421
Step-by-step explanation:
There are two diagrams, one for 0.137, and one for 0.284.
I'll go place by place from least to greatest.
First, add 7 thousandths and 4 thousandths.
That will equal 11 thousands. That's greater than 9, so add 1 hundredth to the equation.
(0.1 + 0.2) + (0.03 + 0.08 + 0.01) + 0.001
Now, add 3 hundredths and 8 hundredths.
That will equal 11 hundredths. Add the other hundredth from the regrouping of the thousands for 12 hundredths. That is also greater than 9, so add 1 tenth to the quation
(0.1 + 0.2 + 0.1) + 0.02 + 0.001
Then, add 1 tenth and 2 tenths.
That will equal 3 tenths. Add the other tenth from the regrouping of the hundredths to get 4 tenths.
0.4 + 0.02 + 0.001
Now add 0.4, 0.02, and 0.001.
0.42 + 0.001
0.421
The answer to 0.137 + 0.284 equals 0.421.
The height is 52 feet.
Using t=3, we have:
-3² + 15(3) + 16 = -9 + 45 + 16 = 52
Answer:
-7, 1
Step-by-step explanation:
The roots of an equation are the answers to the equation, where the graph of the equation intersects the x-axis. One can see that the points at which the graph intersect the x-axis are the following,
(-7, 0) and (1, 0), therefore the roots to the equation are the following;
-7, 1
Answer:
11
Step-by-step explanation:
7/8 divided by 1/8 = 7 & 2^2 = 4. Simplified, you would have 7 + 4, or 11
