Answer:
Step-by-step explanation:
d=20t+1/3, b=30t
20t+1/3=30t
10t=1/3
t=1/30 hr
t=(1/30)60=2 min

I just took the test
Answer:
Proven
Step-by-step explanation:
Let ABC be a triangle and D, E and F are midpoints of BC, CA and AB.
The sum of two sides of a triangle is greater than twice the median bisecting the third side,
Hence in ΔABD, AD is a median
⇒ AB + AC > 2(AD)
Hence, we get
BC + AC > 2 (CF
)
BC + AB > 2 (BE)
On adding the above inequalities, we get
(AB + AC) + (BC + AC) + (BC + AB )> 2 (AD) + 2 (CD) + 2 (BE
)
2(AB + BC + AC) > 2(AD + BE + CF)
AB + BC + AC > AD + BE + CF - Proven

Eh i tried answering this but i think i got the wrong answer. but i would put the cone’s volume at the beginning of the volume equation, the replace the R and H with x since they’re the same. Then solve for x.
So like, 3,532.5 = (pi)(r^2)(x/3)
1) The value of 6s in 36,621 are 6,000 and 600.
first 6 is in the thousands place value while the second 6 is in the hundreds place value.
6 x 1000 = 6,000 and 6 x 100 = 600
2) The first 4 is ten times greater than the second 4 is shown in 354,426
the first 4 is in the thousands place value while the second 4 is in the hundreds place value
4 x 1000 = 4000 and 4 x 100 = 400
based on the question the first 4, which is 4000, is ten times greater than the second 4, which is 400.
we can check if this statement is true either by dividing 4000 by ten or multiplying 400 by ten.
4000/10 = 400 ; 400 x 10 = 4000. therefor, out of the 4 numbers given, the correct one is 354,426
3) The relationship of the two 5s in 552 is shown in 500 ÷ 50 = 10
based on its place value, the first five is in the hundreds place and the second five is in the tens place.
500 ÷ 50 = 10. This equation states that 500 is ten times greater than 50.
4) In 2,077 the first 7 is greater than the second 7 by 10 times.
using place value, first 7 is in the tens place while second 7 is in the ones place.
first 7 is 70; second 7 is 7. we divide 70 by 7 to know how many number of times 70 is greater than 7.
70 ÷ 7 = 10 times.
