3 cakes in 2.5 hours
Divide 7.5 (hours you are solving for) by 2.5 (known hours for 3 cakes)
7.5/2.5=3
Multiply that answer, 3 * 3= approximately 9 cakes in 7.5 hours
1.

4 + 7 or 4 - 7 = 11 or -3

Answer:
Sample space: {Black, Red, Blue, Brown, Purple, Yellow, Green}
Simple event
Step-by-step explanation:
Sample space is a list of all the possible outcomes.
This is a simple event because you are only doing one event, such as choosing marbles from a bag.
A compound event would be multiple simple events, such as flipping a coin <em>and</em> rolling a dice.
Answer:
A and C
Step-by-step explanation:
- A right triangle consists of two legs and a hypotenuse.
- To find hypotenuse, we use The Pythagorean Theorem
- The Pythagorean Theorem =

- two legs meet at a 90° angle and the hypotenuse is the longest side
3 - 4 - 5
6 - 8 - 10
7 - 24 - 25
5 - 12 - 13
are some basic right triangle
(about more, look picture)
<em><u>Just use hypotenuse formula :</u></em>
3 x 3 = 9
4 x 3 = 12
5 x 3 = 15
Option C is correct

Option A is correct

But B isn't correct
Hope this helps ^-^
