Answer:
a). 18 minutes
b). 8.4 miles
Step-by-step explanation:
a). Let Luis meet Kristina after the time = h hours
So the distance traveled by Luis in h hours = Speed × time
= 8×h
= 8h miles
If Kristin started after 45 minutes of 
hours then the distance traveled by her
= Speed × time
= 
miles
Since after h hours distances traveled by Luis and Kristin are same so,
28h - 8h = 
20h = 21
h = 1.05 hours
So the time taken by Kristin = (h - 0.75)
= 1.05 - 0.75
= 0.30 hours ≈ 18 minutes
b). Distance traveled by Luis before Kristin catches Luis = 8×1.05
= 8.4 miles
It’s 25.5 because since 25 off of 100 equals 75, you times the 34 by .75
Answer:
<h2>1.326 ......</h2>
Step-by-step explanation:
³√81 = 4.326
³√216 = 6
⁴√16 = 2
√225 = 15
<h3> X = ³√81 - 8 ³√216 + 15 ⁴√16 + √225 </h3>
X = 4.326 - (8×6) + (15×2) + 15
X = 4.326 - 48 + 30 + 15
X = 49.326 - 48
X = 1.326 ............
A direct variation is a linear equation. It describes a simple relationship between two variables.
Example: if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3.

Answer:
2750 chocolates
Step-by-step explanation:
Find how much she has bought already:
1,125(2)
= 2,250
Then, subtract this from 5,000
5000 - 2250
= 2750
So, she still needs 2750
