Answer:
The area of the figure is 143 sq in
Step-by-step explanation:
10 in * 7 in = 70 sq in
12 in * 4 in = 48 sq in
5 in * 5 in = 25 sq in
A = 70 sq in + 48 sq in + 25 sq in
A = 143 sq in
To find this you can always use a calculator, if your teacher allows you to. Just remember to punch in the negative signs correctly and don't mistake them for subtraction signs. Also if you don't know what product means, that means the answer of a multiplication problem so for example 9 is the product of 3x3 or 5 is the product of 5x1. The answer to your question is 104. Maybe next time you can solve it on your own! :)
Try B, hope that helps :)
Answer:
64
Step-by-step explanation:
Let us consider E_abc to be the event that a, b and c appear on the first, second and third slot of the spin machine.
Now, we are told that each slot has 4 possibilities which are a cherry, a lemon, a star, or a bar when spun.
Thus, from mn rule in probability, the total number of simple events in the sample space is = 4³ = 64
