On seeing the place value of unit digits, we first multiply the unit digits.

If there is a carry over, we add it with the product of unit digit of the first number with the tenth digit of the second number. We accomplish this task by seeing the place values at the respective digits.

Then, we multiply the tenth digit of the first number with the unit digit of the second number by seeing their place values and repeat the process we did before.

By this way, place values are useful for multiplying two digit numbers.

The County Fair has to 2 ticket options.Option 1 has an entry fee of $5 and charges $0.65 per ride per ride. Option 2 has an ent

Ugo [173]

For 25 tickets total cost of option one and option two to be the same.

Step-by-step explanation:

Let us assume the total number of rides = m

for which BOTH options cost same.

Case: 1

The cost of entry fee = $5

The cost per ride = $0.65

So, the cost of m rides = m x ( Cost of 1 ride )

= m x ($0.65 ) = 0.65 m

Cost of purchasing m tickets in first ride = Entry Fee + Per ticket cost

= 5 +0.65 m ..... (1)

Case: 2

The cost of entry fee = $10

The cost per ride = $0.45

So, the cost of m rides = m x ( Cost of 1 ride )

= m x ($0.45 ) = 0.45 m

Cost of purchasing m tickets in second ride = Entry Fee + Per ticket cost

= 10 +0.45 m ..... (2)

Now, equating (1) and (2), we get:

5 +0.65 m = 10 +0.45 m

or, 0.20 m = 5

or, m = 5/0.20 = 25

or, m = 25

Hence, for 25 tickets total cost of option one and option two to be the same.

If the velocity of a bicycle is 10 m/s how long will it take to cover a distance of 18 km<br>

Sergeeva-Olga [200]

Answer:

time taken=1800 seconds

Step-by-step explanation:

velocity=v=10m/s

distance=S=18km=18×10³m=18000m

t=?

as we know that

velocity= $\frac{distance covered}{time taken}$

velocity×time taken=distance covered

now here we have to find time

time taken= $\frac{distance covered}{velocity}$

time taken= $\frac{18000m}{10m/s}$

time taken=1800seconds

Divide 28 cans of soda into two groups so the ratio is 3 to 4

kaheart [24]

First, you add the two ratio numbers to figure out what to divide your 28 cans of soda by.

3=4=7
Next, you divide this amount into your total amount of cans of soda.

28/7=4.

This means that for each one in the ratio, there is 4 cans. So you multiply both numbers in the ratio by 4.

3*4 = 12
4*4=16

So, your final answer is 12:16, or 12 cans of soda in one group, and 16 cans of soda in the other.
