Answer:
1.67 hours
Step-by-step explanation:
Let the original speed of Jonathan = 
units/hr
Let the original time taken by Jonathan = 
hours
Let the distance = 
units
Formula for distance is given as:
Given that half the distance is covered by original speed.
Half the distance is covered by increasing the rate by 25%.
i.e. increased speed:
Hence, Time taken:
Distance traveled is half of the total distance:
Dividing (1) by (2):
Answer:
because x^n+1 =
the number which is n and n is an odd number and my odd number is 3 so
x^3+1= 4
= x^4
Answer:
Step-by-step explanation:
number of side = n =7
Sum of all the angles of given polygon = (n -2)*180 = 5 *180 = 900
x + 140 +133 +145 + 117 + 119 + 125 = 900
x + 779 = 900
x = 900 - 779
x = 121
Answer:
yes, the volume = 16 ft^3
Answer:
31.5 units^2
Step-by-step explanation:
Rectangle area (RA) = l × w
Triangle area (TA) = (bh)/2
RA = 3 × 7
RA = 21
TA = (7 × 3)/2
TA = 21/2
TA = 10.5
(Triangles are congruent as shown by the lines on each side of the triangle so I can calculate area of both of them together as I just did)
Add areas together
21 + 10.5 = 31.5
