Answer:
P(rolling a 2) = 1/6
Step-by-step explanation:
A standard cube has 6 sides, numbered from 1 - 6.
You are solving for the:
P(rolling a 2).
There is only one side that is number 2, out of the 6 sides, so your answer is:
P(rolling a 2) = 1/6

Answer:
<h3>
m∠D = 80°</h3>
Step-by-step explanation:
In similar triangles corresponding angles have the same measure.
Let Q= the number of quarters and D= the number of dimes.
Q+D= 40 coins
0.25Q+0.1D= $7.75
Rewrite equation 1 as: D = 40-Q and substitute into equation 2
0.25Q+0.1(40-Q)= 7.75 Simplify the left side
0.25Q+4-0.1Q= 7.75 Subtract 4 from both sides
0.25Q-0.1Q= 3.75 Convime like terms on left side
0.15Q= 7.75 Divide both sides by 0.15
Q=25 and D= 40-Q
D= 40-25 which is 15
So Jenna had 25 quarters and 15 dimes.
<span>To check multiply 25 x 25 and 15x10 which equals 625 and 150 this equals 775 so this is 7.75</span>
