Answer:
10,120cm³
Step-by-step explanation:
Volume of pyramid formula:
l = length
w = width
h = height
Plug in the numbers:
V = 46*20*33/3
V = 10120
I think you mean mixed number fractions. So what you do is just subtract, both the fraction and also the number. So for example 1 2/3 - 1 1/3 is just 1/3 because you subtracted both of them
Answer:
Average Speed is 65 km/hr
Step-by-step explanation:
To get the average speed, first we have to calculate the time spent in the round trip .
Speed= Distance/ time
So, Time= Distance/Speed
Time Outgoing= 300km/ 97km/hr
Time Outgoing=3.0927 hr
Time lunch break =1 hr
Time return= 300km/ 58km/hr
Time Outgoing=5.1724 hr
Total= 3.0927 hr+1 hr+5.1724 hr=9.2651
To get average speed, we have to divide all the distance by the time it took al the trip.
Average Speed= Distance/ time
Average Speed= 600km/9.2651 hr= 64,76 km/hr
Average Speed=64,76 km/hr ≅ 65km/hr
Answer:
x=2.2582, y=19.91/9. (2.2582, 19.91/9).
Step-by-step explanation:
5x+4y=20.14
6x+7y=28.15
-------------------
6(5x+4y)=6(20.14)
-5(6x+7y)=-5(28.15)
------------------------------
30x+24y=120.84
-30x-35y=-140.75
--------------------------
-9y=-19.91
9y=19.91
y=19.91/9
5x+4(19.91/9)=20.14
5x+79.64/9=20.14
5x=20.14-79.64/9
5x=11.291
x=11.291/5
x=2.2582
Answer:
y= 40
Step-by-step explanation:
The sum of the angle of a triangle is 180
2y+ 50 + y+10 = 180
Combine like terms
3y + 60 =180
Subtract 60 from each side
3y +60-60 = 180-60
3y = 120
Divide by 3
3y/3 = 120/3
y= 40
