Answer:

80% of the people picked chocolate cake

Step-by-step explanation:

If you add the people (Not including her) up in the party, you will get 50 people in which both include chocolate cake and coconut cake. We can see that 40 people picked chocolate and 10 for coconut. 40 of 50 is 80% because 10% of 50 is 5 so 40/5 = 8, thus making it 80%. Hope this helps!

Help me please explain do not need work just explain THANK YOU I NEED HELP

Alright, 

you will need to solve for each variable to find if they got the equation correctly or not.. 

Let's start with h 
isolate h 
(1/2)h = A/(b1+b2)
Now we need to get rid of 1/2 we may do so by multiplying both sides by 2 

h = 2(A/(b1+b2))

And that's not how they did it for h so Option D doesn't apply 


Let's see C
Also doesn't apply since they multiplied 2 only by A rather than A/h

Let's see B
Also not correct they made the same mistake as with option C

Let's see A
again same mistake 
when multiplying both sides by 2 
the 2 should be as following 
2\frac{A}{h}

I believe you should contact your instructor and explain that non of the options is right.

Which function has zeros at x = 10 and x = 2? f(x) = x2 – 12x + 20 f(x) = x2 – 20x + 12 f(x) = 5x2 + 40x + 60 f(x) = 5x2 + 60x +

To find the correct function, just plug in 10 and 2 to see if the function equals zero with both numbers.

f(x)=x^2-12x+20
f(10)=100-120+20
f(10)=0         --> that's what we want, so let's check the other number

f(x)=x^2-12x+20
f(2)=4-24+20
f(2)=0          --> perfect. this function has zeros at both x=10 and x=2

The function that has zeros at both x=10 and x=2 is f(x)=x^2-12x+20.

10 is 20 degrees

11 is 180-145= 35 degrees

12, so the way you do it is by the fact that one opposite exterior angle is equal to two interior angles, so 40+46= 86 degrees.

8 is 86-35= 51 degrees

9 is 29 plus 62 equals 91 degrees.

Hope this helps! I tried to type this really fast
