According to the diagram the answer is 36degree
Answer:
5.6x-16.9=-0.1
28x/5-16.9=-0.1
28x/5-16.9=-0.1
28x/5-16.9+16.9=-0.1+16.9
28x/5=16.8
x=3

Answer:
40 nickles
Step-by-step explanation:
Here is the correct question: Earl went to the store and realize he had 7 more Nickles in his pocket then he thought he had; If all the change in earl’s pocket is nickles, he had $2.35 in his pocket, how many more nickles did he think were in his pocket
?
Given: All Nickles in the Earl´s pocket is $2.35.
Remember, 1 Nickles = $.05
∴ Converting the dollar to nickels
$2.35= 
Earl had total 47 nickels in his pocket.
∴ Earl earlier had nickles = 
∵ we know Earl had realized that he had 7 more nickles in his pocket, which means he already had 40 nickles to make $2.35.
30 for 8 because for 2$ more you can have 10
Answer:
For a general quadratic equation like:
y = a*x^2 + b*x + c
a is the leading coefficient.
And we define the vertex of this as (h, k)
Where h is:
h = -b/(2*a)
and k is the y-value given when we use x = h.
Now, in this case we have:
f(x) = 5*x^2
We can see that the leading coefficient is 5, then a = 5.
To find the value of h we use:
h = -b/(2*a)
there is no lineal term, thus b = 0, then:
h = -0/(2*5) = -0/10 = 0
and k is given by
f(h) = f(0) = 5*0^2 = 0
then k = 0.
Concluding:
a = 5
h = 0
k = 0
