Answer:
Increasing a number by 5% and then by 20% is the same as increasing the original number by 26%.
Step-by-step explanation:
Take a number, x.
Now increase it by 5%.
1.05x
Now increase it by 20%.
1.2 * 1.05x = 1.26x
1.26x = 126% of x = 100% of x + 26% of x
100% of x is the same as x, so it is the same as the original x.
The increase is 26% of the original number.
Increasing a number by 5% and then by 20% is the same as increasing the original number by 26%.
<span>miles per gallon uses ratios. Say your car was doing 80 miles for 4 hours. You would have the ratio 80;4 and you need to find the miles per 1 hour</span>
Answer:
Yes
Step-by-step explanation:
In right-angled triangles, the Theorem of Pythagoras can be applied. (The hypotenuse squared is equal to the sum of the other two sides squared).
The hypotenuse is always the longest side, therefore if it's a right-angled triangle:
15²+35² should equal to 38² and in this case it does.
Answer:
The limit of the function as x approaches -2 is 6.
Step-by-step explanation:
The first step is to graph the function using a graphing utility and later determine the limit from the graph.
The graph of the function is shown in the attachment below.
The limit of the function as x approaches -2 is 6, as indicated on the graph
