Answer:
Square Root of 40 to the Nearest Tenth
Square Root to the nearest tenth
Square Root of 40 to the nearest tenth, means to calculate the square root of 40 where the answer should only have one number after the decimal point.
Here are step-by-step instructions for how to get the square root of 40 to the nearest tenth:
Step 1: Calculate
We calculate the square root of 40 to be:
√40 = 6.32455532033676
Step 2: Reduce
Reduce the tail of the answer above to two numbers after the decimal point:
6.32
Step 3: Round
Round 6.32 so you only have one digit after the decimal point to get the answer:
6.3
To check that the answer is correct, use your calculator to confirm that 6.32 is about 40.

Answer:
1800(5/6)^t
Step-by-step explanation:
I don't see any answer choices, but this would be another form if it is listed. The negative exponent means that you get the reciprocal of the fraction (in this case 1.2). This turns 1.2 into (1/1.2), which is equivalent to 5/6.
Answer:
<u><em>(-1,1)</em></u>
Step-by-step explanation:
We can solve this by either graphing and finding ther point the lines intersect, or mathematically, I'll do both.
<u>Graphing:</u>
<u>Mathematically:</u>
−2x + 4y = 6
y = 2x + 3
See the attached graph. The lines intersect at (-1,1)
--------------------
I'll rearrange the first equation (to make it easier for me):
−2x + 4y = 6
4y = 2x + 6
y = (1/2)x + 1.5
Now lets substitute the second equation into the first so that we can eliminate y:
y = 2x + 3
[(1/2)x + 1.5] = 2x + 3
- (3/2)x = (3/2)
x = -1
If x = -1:
y = 2(-1) + 3
y = 1
The solution is x = -1 and y = 1, or (-1,1)
=================
Both approaches give us (-1,1), the solution to the system of equations. It is the only point that satisfies both equations.
Answer:
x = 5
Step-by-step explanation:
6/18 = x/(20-x)
1/3 = x/(20-x) Multiply both sides by 20-x
(20-x)/3 = x Multiply both sides by 3
20-x = 3x Add x in both sides
20 = 4x Divide both sides by 4
5 = x
