36 square pieces of cake can be cut from the rectangular cake.
"A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles."
"A square is a shape that has four straight sides of the same length and four angles of 90 degrees"
It is given that the cake is a rectangle and squares are cut from it.
To find the area of the cake:
Area = 22.5 × 10
= 225
The area of each square piece cut from the cake:
Area = 2.5²
=6.25
To find the number of pieces cut, divide the area of the cake by the area of each piece.

Answer:Rates. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
Step-by-step explanation:
P(the king of diamonds) =
b.
Pla heart) =
P(a red three) =
d.
P(a red card) =
Answer:
Step-by-step explanation:
(King of Diamonds) = 1/52
(A Heart) = 1/4
(Red Three) = 1/26
(Red Card) = 1/2
B) What is the probability of Lydia rolling pairs of the same number?
C) What is the probability that at least one number will be a 3?
b) The probability of Lydia rolling pairs of the same number is 1/6.
c) The probability that at least one number will be a 3 is 11/36
Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
a) The Sample Space is
(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)
(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)
(3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6)
(4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)
(5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6)
(6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)
b) The probability of Lydia rolling pairs of the same number
= 6/36
= 1/6
c) The probability that at least one number will be a 3
= 11/36
