The square root of 81 equals 9. This can be known through understanding the roots of perfect squares. After this, you multiply 8 x 9 to get a final answer of 72.
Answer:
12.5 minutes
Step-by-step explanation:
When working together,It takes two computers 10 minutes to send out an email
It takes the slower computer 50 minutes to send out an email
Let x represent the time taken by the faster computer to do the job in its own
Therefore, the time required by the faster computer can be calculated as follows
1/x + 1/50= 1/10
Collect the like terms
1/x= 1/10-1/50
1/x= 4/50
Cross multiply both sides
4 × x = 50×1
4x=50
Divide both sides by the coefficient of x which is 4
4x/4=50/4
x= 12.5
Hence the time taken by the faster computer to finish the job on its own is 12.5 minutes
Name if a b and c are opposite adjacent or hypotenuse
Answer:
OPTION C: h(x) = x - 3
Step-by-step explanation:
To find the inverse of the function y = x + 3.
Swap 'x' and 'y'.
We get x = y + 3.
Solve for 'y' now.
We get y = x - 3
Therefore, the inverse function becomes h(x) = x - 3.
<u><em>Answer:</em></u>
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
