7 and 7/28 I think if I did that right
Answer:
y = 12
Step-by-step explanation:
Looking at the large triangle
tan 30 = opposite / adjacent
tan 30 = 4 sqrt(3)/ y
Multiply each side by y
y tan 30 = 4 sqrt (3)
We know tan 30 = sqrt(3)/3
y * sqrt(3)/3 = 4 sqrt(3)
Multiply each side by 3/ sqrt(3) to isolate y
y * sqrt(3)/3 * 3/ sqrt(3) = 4 sqrt(3) * 3 /sqrt(3)
y = 12
Answer: b. $22.75
Step-by-step explanation:
Given : A large pizza with no toppings costs $14.00. A large pizza with 2 toppings costs $17.50.
Let x denotes the number of toppings and y be the cost of that pizza.
Then, 
, m= cost per topping and c= cost of pizza without any topping.
From the given information.
c= $14
Function of cost becomes = 
For x= 2 and y= 17.50, we have
tex]3.50=m(2)[/tex] [Subtract 14 from both sides]
[Divide both sides by 2]
For c= 14 and m =1.75 , our function becomes.
Now, for x= 5
Hence, the cost of a pizza with 5 toppings = $22.75
Since we tossed 2 dice, the sample space : 6 x 6 = 36 outcomes:
{(1,1), (1,2),(1,3),(1,4),(1,5),(1,6)
{(1,2),(2,2),(3,2),(4,2),(5,2)),(6,2)
{------------------------------------------
-----------------------------------------
{(1,6),(2,6),(3,6),(4,6),(5,6),(6,6)}
What are the number that their sum is equal to 5:
1+4 =5
4+1 =5
2+3 =5
3+2 =5
Total favorable outcomes = 4:
So the probability of getting a sum of 5 is P(sum=5) = 4/36 = 1/9 = 0.111
