Answer:
m = 90 - 6d
Step-by-step explanation:
Harita is to memorize 90 measure of music for the concert.
If she plans on memorizing 18 measures for 3 days, it means per day she would memorize 18/3
= 6 measures
m = 90 - 6d (where d = days)
Answer:
11n
Step-by-step explanation:
7+4 =11
so then 7n+4n=11n
Answer:
1.5 minutes.
Step-by-step explanation:
The relative speed at which the car behind travels compared to the other car is 90 - 70 = 20 km/hr.
The time taken to travel 500 m ( =0.5 km) is 0.5 / 20 = 0.025 hours.
= 0.025 * 60 = 1.5 minutes.
Answer:
b pick 3 marbles form a bag of 10 different colored marbles
Step-by-step explanation:
Ok so
surface area=area around+2(area of top)
are of top=circle=pir^2
area around=hiehg times circumference=h2pir or hpid
surfacea rea=2hpir+2pir^2
h=9
r=4
SA=2(9)(3.14)(2)+2(3.14)(2^2)
SA=36(3.14)+8(3.14)
SA=113.04+25.12
SA=138.16
tahat is 1
multiply y 1500 since you want 1500 boxes
138.16 times 1500=207240 in^2
surface area=138.16 in^2
number of square feet of cardboard=207,240 in^2
triangular prism formula=1/3(LWH)
trippleing would be
TPA=1/3(3L3W3H)
TPA=1/3(27LWH)
TPA=27(1/3(LWH))
the result is a volume that is 27 times as large as the original
if both height and base are tripled, then
area of base=1/2(bh)
new is 1/2(3b3h)
1/2(9bh)
9(1/2(bh))
9 times as lage
tripling the other height means the previous one times 3 which is 27
answers are
138.16 in^2
207,240 in^2
9
27
