Find how fast she runs 1 km:
18/2 = 9 minutes.
So we know have K = 9t
Subtract 18 from both sides:
K-18 = 9t -18
Rewrite the right side:
K-18 = 9(t-2)
Is there a b ok but it’s A
Answer:
x = 3/2 or x = -5/4
Step-by-step explanation:
Solve for x over the real numbers:
8 x^2 - 2 x - 15 = 0
Using the quadratic formula, solve for x.
x = (2 ± sqrt((-2)^2 - 4×8 (-15)))/(2×8) = (2 ± sqrt(4 + 480))/16 = (2 ± sqrt(484))/16:
x = (2 + sqrt(484))/16 or x = (2 - sqrt(484))/16
Simplify radicals.
sqrt(484) = sqrt(4×121) = sqrt(2^2×11^2) = 2×11 = 22:
x = (2 + 22)/16 or x = (2 - 22)/16
Evaluate (2 + 22)/16.
(2 + 22)/16 = 24/16 = 3/2:
x = 3/2 or x = (2 - 22)/16
Evaluate (2 - 22)/16.
(2 - 22)/16 = -20/16 = -5/4:
Answer: x = 3/2 or x = -5/4
Answer:
5
Step-by-step explanation:
1) origin point is (0;0);
2) the required distance is:
<u><em>You want to leave a 18% tip on a meal that cost $150.</em></u>
<u><em>First, convert the 18% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 18%) by 100%.So, the conversational term "18%" becomes 18% / 100% = 0.18 in terms of a real mathematical number.</em></u>
<u><em>Second, you need to find out what 18% of your $150 meal cost is.This is always done by multiplying 0.18 by $150.00, or</em></u>
<u><em></em></u>
<u><em>0.18 x $150.00=$27.00.</em></u>
<u><em>So, the amount of tip you are going to leave is $27.00.</em></u>
<u><em></em></u>
<u><em>This makes the total cost of your meal (to write on your charge slip or other payment)</em></u>
<u><em></em></u>
<u><em>$150.00 + $27.00 = $177.00. </em></u>
