Answer:
30m + 75
$255
Step-by-step explanation:
Since John has to pay a monthly fee of 0, you can let m represent the number of months and then add the one time membership fee of $75.
30 multiplied by 6 is 180 and 180 plus 75 is 255.
Equation format for a slope, m and a point (x1, y1)
y - y1 = m(x - x1) (Try and memorize this formula)
8) for (3,-4), m = 6. x1 = 3, y1 = -4, Substituting
y - y1 = m(x - x1)
y - (-4) = 6(x - 3)
y + 4 = 6x - 18
y = 6x - 18 - 4
y = 6x - 22
10) for (-2,-7), m = 4/5. x1 = -2, y1 = -7, Substituting
y - y1 = m(x - x1)
y - (-7) = (4/5)*(x - (-2))
y + 7 = (4/5) *(x +2) 4/5 = 0.8
y + 7 = 0.8x + 1.6
y = 0.8x + 1.6-7
y = 0.8x - 6.4
y = (4/5)x - (64/10)
y = (4/5)x - (32/5)
So same approach to solve others. Cheers.
Yolanda won the race. By 1 yd.
Because every time she runs 10yd, Yoko runs 9 yards. So even if you give her an extra 10yd, she will run them faster than Yoko runs the 10 remaining yards.
Answer:
When you multiply decimals, do not align the decimal points. Simply line up the numbers along the right hand side of the problem. Then multiply just as you would if the numbers were all whole numbers and add at the end.
Step-by-step explanation:
6.2 × 3.2= 19.84
62 × 32= 1984
Hope this helps:)
Answer:
<em>It can be said that 21.34% of the adults were taking the supplement and had a cold</em>
Step-by-step explanation:
<u>General Statistics</u>
The results of field studies usually come in the form of a set of numbers that must be organized and analyzed to take useful information out of them. The data provided in the question comes in a two-way frequency table, which we'll reproduce in a more readable format in the figure below.
We are required to calculate the percentage of adults that were taking the supplement and had a cold. By crossing the second row and the second column we get 108 adults were simultaneously taking the supplements and having a cold, thus the required percentage is computed by dividing that quantity by the total of the adults under study:
It can be said that 21.34% of the adults were taking the supplement and had a cold
