Answer:
48.7 cube inches
Step-by-step explanation:
Let us assume that the ice cream filled the entire volume of the cone.
Diameter of cone = 4 inches
height of cone = 7 inches
diameter of a sphere of ice cream = 5 inches
Total amount of ice cream = volume of cone + volume of sphere
volume of cone = 
h
r = 
= 
= 2 inches
volume of the cone = x 
x 
x 7
= x x 4 x 7
= 29.3333 cube inches
volume of sphere = 
r =
= 
= 2.5 inches
volume of sphere ice cream = x x 
= x x 
= 19.40 cube inches
So that,
Total amount of ice cream = 29.33 + 19.40
= 48.7 cube inches
Answer = 36.0 mph
As per the question,
Actual speed of the car = 40 mph.
Speedometer has a percent error of 10%.
The error can be negative as well as positive.
If the error is negative, it means speedometer is showing less speed than actual speed= - 10%
10 % of 40 = 4
speed shown by speedometer = 40 - (10% of 40) = 36 mph
If the error is positive, it means speedometer is showing more speed than actual speed = +10%
speed shown by speedometer = 40 + ( 10% of 40) = 44 mph
as per the given options, correct option is 36.0 mph
Answer:
D
Step-by-step explanation:
Since it’s asking for numbers between -1 and 8 the equation cannot contain a equal symbol therefore it must be D
Answer:
Amount invested at 8 % rate = x = $ 15000
Amount invested at 9 % rate = 34000 - x = 34000 - 15000 = $ 19000
Step-by-step explanation:
Total Amount = $ 34000
Let amount invested at 8 % rate = x
Amount invested at 9 % rate = $ 34000 - x
Total interest = $ 2910
291000 = 8 x + 306000 - 9 x
x = 306000 - 291000
x = 15000
So amount invested at 8 % rate = x = $ 15000
Amount invested at 9 % rate = 34000 - x = 34000 - 15000 = $ 19000
