No because the opposite of a negative is positive
The problem is asking you to solve for the surface area of the triangular prism. You know that the prism is made up of two triangles and three square surfaces. Adding these surface together, will give you the surface area.
Solving for the surface area:
Surface area of 2 triangles (top and bottom) + Surface area of 3 rectangles (sides)
2 [1/2 (2.6)(3.9)] + [ (4.3)(3.9) + (4.3)(2.6) + (4.3)(5.2) ] = 60.45 cm^2 surface area
The number of cards is 3/8 of 48.
In math, "of" usually means "times."
3/8 of 48 = 3/8 * 48 = 3/8 * 48/1 = (3 * 48)/(8 * 1) = 144/8 = 18
Answer: 18 cards
Answer:
x= 27
Step-by-step explanation:
<em>A right angle has to equal 90 degrees, no matter what,</em>
<em>So what times 3, plus 9, will give you 90? 27.</em>
<em>So 27 x 3 + 9 equals 90!</em>

Since Tameka has 30% worth of a dollar. The total value of the coins in her purse = 0.30* $1 = $0.30 or 30 cents
Total worth of coins in Tameka's purse = 30 cents
The coins that are available are 1 cent coin, 5 cents coin (nickel), 10 cent coin (dime) or a 25 cent coin (quarter)
The only possible way for her to have 4 coins that add up to 30 cents is that she has two dimes and two nickels
2 dimes + 2 nickels = 2 *10 + 2* 5 = 20 + 10 = 30 cents
Answer: 2 dimes (10 cent coins) and 2 nickels ( 5 cent coins)
