Answer:

LCD of 7 and 5 is 35

Step-by-step explanation:

In many cases, you can find the lowest common denominator by simply multiplying the two numbers together. This method works in your example.

7 x 5 = 35

The two fractions would become 15/35 and 28/35

There will be times when this will not get you straight to the answer, eg find the lowest common denominator of 8 and 12. For this you need to list some multiples of the numbers until you get a number which appears in both lists:

8: 8, 16, 24

12: 12, 24

So, the lowest common denominator of 8 and 12 is 24.

Tickets to a show cost $5.50 for adults and $4.25 for students. A family is purchasing 2 adult tickets and 3 student tickets.
jarptica [38.1K]

The exact cost is $23.75 for the show, and the exact change they should get is $1.25.

An adult ticket to the show costs $5.50

A student ticket to the show costs $4.25.

A family buys two adult tickets and three student tickets. This would imply that the total cost of two adult tickets would be

⇒ 2 × 5.5 = $11

It also implies that the total cost of three student tickets is

3 × 4.25 = $12.75

The total cost of two adult tickets and three student tickets is

⇒ 11 + 12.75 = $23.75

If the family pays $25, the exact change they should get is

⇒ 25 - 23.75 = $1.25

Thus, the exact cost is $23.75 for the show, and the exact change they should get is $1.25.

Find the area of each figure. Use 3.14
grigory [225]
<h3>Answer:  23.13 square meters</h3>

===============================================================

Explanation:

The top and bottom semicircles can be joined to form a full circle. The same can be said about the left and right semicircles. Each circle has diameter 3 and radius 1.5

The area of one circle is

A = pi*r^2

A = 3.14*(1.5)^2

A = 7.065

So two circles doubles to 2*7.065 = 14.13 square meters in area.

Then the last step is to add on the area of the 3 by 3 square (area 3*3 = 9) to get 14.13+9 = 23.13

This area is approximate because pi = 3.14 is approximate. Use more decimal digits in pi to get a more accurate area. However, your teacher wants you to use this specific value so it's best to stick with 23.13

A single document that ties together the frequently disparate interests of parties involved in a conflict is used in a single-text negotiating strategy, a type of mediation.
