Answer:
$276
Step-by-step explanation:
Create a proportion where x is the cost to refinish the larger wood floor:
= 
Cross multiply and solve for x:
3x = 828
x = 276
So, to refinish the larger wood floor, it would cost $276
Answer:
Step-by-step explanation:
Exponential equations have the form of a geometric sequence
(x + 3)^2 + (x + 4)^2
= x^2 + 6x + 9 + x^2 + 8x + 16
= 2x^2 + 14x + 25
= 2(x^2 + 7x) + 25
= 2[(x + 7/2)^2 - 49/4] + 25
= 2(x + 7/2)^2 - 98/4 + 25
= 2(x + 7/2)^2 + 1/2
Its B
The plumber worked for 5 hours because 450-200=250 which gets rid of the initial fee so 250 divided by 50 is 5
Answer:
Mean: 33.454545 Median: 34.5 Mode: 25
Step-by-step explanation:
By putting all of the numbers in numerical order, then adding them and dividing them by 11 (the number of numbers in the list), you get 33.45 repeating as the mean. With the organized list of numbers find the middle number, which is 35, and that is the median. The mode, the most common number in the sequence, is 37 and 25.
25+25+27+28+32+35+37+37+39+41+42=368
368/11=33.45454545
