Given:
Rectangular room is 10 feet; and
1 x 1 ft tiles
The expression for this problem would be:
If we know that the width is w, while the length is w + 10,
therefore the perimeter is 2w + 2 (w + 10), so you need 4w + 20 - 4, or 4w + 16
tiles. Since you do not want to count the corners, twice.
Answer:
The value could replace q is 108 - n ⇒ the last answer
Step-by-step explanation:
* Lets study the values of quarters and nickles
- One quarter = 25 cents
- One nickle = 5 cents
- The number of coins is 108
- The coins are nickles or quarters only
- The coins worth $ 21
* Lets solve the problem
∵ The number of coins is 108 coins
- Let the quarter is q and the nickel is n
∴ q + n = 108 ⇒ (1)
∵ The coins worth $21
∵ $ 1 = 100 cents
∴ $21 = 21 × 100 = 2100 cents
∵ The quarter = 25 cents
∵ The nickels = 5 cents
∴ 25q + 5n = 2100 ⇒ (2)
- To find the value which replace q use equation (1)
∵ q + n = 108 ⇒ subtract n from both sides
∴ q = 108 - n
* The value could replace q is 108 - n
Answer: See below
Step-by-step explanation:
From the figure attached below,
We know that by the SSS property, the two triangles are congruent
Using the property of congruence to find the measure of all these angles:
Therefore, the measure of the angles are:
