Answer:
All units for volume are units cubed. units^3
Step-by-step explanation:
1. P(pen then pencil) = 15/25 × 10/25 = 3/5 × 2/5 = 6/25
2. P(pen then pencil) + P(pencil then pen) = 6/25 + 6/25 = 12/25
3. P(pencil then pencil) = 10/25 × 10/25 = 2/5 × 2/5 = 4/25
4. P(at least 1 pen) = 1 − P(no pen) = 1 − 4/25 = 21/25
425 / 50 = 8,5
There you go.
To find the volume of a square-based pyramid, use the formula V = A(h/3), where V is the volume and A is the area of the base.
$1.87
60 cents in pennies = $.60
Each quarter is $.25, each dime is $.10, and each nickel is $.05.
1.87=q*.25+d*.10+n*.05+.60
