A movie theater has n rows and m seats in each row. If each ticket costs $5.60, how much do all tickets to one movie cost?

docker41 [41]

Answer:

All Tickets to one movie cost $\$5.60 \times m\times n$

Step-by-step explanation:

Given:

Number of rows in theater = n

Number of seats in each row = m

Total number of seats in the theater = Number of rows in theater $\times$ Number of seats in each row= $m \times n$

Now given each ticket costs = $\$5.60$

So to find total of all tickets we need multiply each ticket cost by Total number of seats in the theater

Total tickets cost = each ticket cost $\times$ Total number of seats in the theater = $\$5.60 \times m \times n$

A pile of sand has a weight of 90kg.

ankoles [38]

Answer:

9Kg, 18Kg and 63 Kg

Step-by-step explanation:

Sum the parts of the ratio, 1 + 2 + 7 = 10 parts

Divide the weight of sand by 10 to find the value of one part of the ratio

90 Kg ÷ 10 = 9 Kg ← value of 1 part of the ratio, thus

2 parts = 2 × 9 Kg = 18 Kg

7 parts = 7 × 9 Kg = 63 Kg

Thus the weights of each bag are 9 Kg, 18 Kg and 63 Kg
