A number,M, is rounded to 1 decimal place. the result is 9.4 complete the error interval for M​
ivann1987 [24]

Answer:

9.35 \le M \le 9.45

Step-by-step explanation:

Given

M = 9.4 to 1 d p

Required

The error interval

The error interval is represented as:

Lower \le M \le Upper

Where

Lower = M - 0.05

Upper = M + 0.05

So, we have:

Lower = M - 0.05

Lower = 9.4 - 0.05

Lower = 9.35

Upper = M + 0.05

Upper = 9.4 + 0.05

Upper = 9.45

Hence, the error interval: Lower \le M \le Upper is:

9.35 \le M \le 9.45

the length of one leg of a right triangle is 6 feet. the length of the hypotenuse is 2 ft longer than the other leg. Find the le
Minchanka [31]

Answer:

The missing leg is 8 feet and the hypotenuse is 10 feet.

Step-by-step explanation:

Use the Pythagorean theorem which is A²+B²=C².

So we know the first side is 6 so plug that into the equation which would now be 6²+B²=C².

Because the hypotenuse is 2 feet longer than the missing leg we can plug in C=B+2 which would now make it 6²+B²=(B+2)².

Now we solve what we have so far which would now make the equation 36+B²=B²+4B+ 4.

Now we can figure out that 4B=32.

Now isolate the variable, B, by divide both side of 4B=32 by 4.

This gives us B=8.

So the other side is 8 feet.

Since we know that the hypotenuse is 2 feet longer than the leg we just add 2 feet to the original 8 feet to find the hypotenuse to be 10 feet.
