Answer:
Robin= 750
Sharon= 720
Step-by-step explanation:
let the total marks obtained be X
from question, Robin = 5X/6
Shaon= 4X/5
then, 5X/6= 4X/5+30
or, 5X/6= 4X+150/5
or 25X=24x+900
or,X= 900
therefore robin=750
Shaon = 720
How fast the distance between them decrease is 16mph
<h3>How to calculate the speed of an object?</h3>
Given the following parameters
Speed of the hiker = 6mph
If is it 3/11 the rate of a cyclist, then the rate of the cyclist will be:
6 = 3x/11
3x = 66
x = 22mph
Distance between them = 22 - 6
Distance between them = 16mph
Hence how fast the distance between them decreases is 16mph

Step-by-step explanation:
The picture in the attached figure
the question is
What is the surface area of the ramp?
we know that
surface area=2*[(36+12)*5/2]+2*[15*13]+[12*15]+[36*15]
surface area=240+390+180+540
surface area=1350 in²
the answer is1350 in²
Answer:
False, becasue 8*1/2 is 4 and 4 doesn't equal 16
