1. 2.85 I'm dumb at math so I will just give the first answer.. xD
Answer:
5/8 are spelled incorrectly
Step-by-step explanation:
There are 16 words
He spelled 6 correctly
That means he spelled 16-6 = 10 incorrectly
The fraction spelled incorrectly is wrong/total
10/16
Simplify by dividing the top and bottom by 2
5/8
Answer:
That day 51 child tikets were sold
Step-by-step explanation:
To do this problem we have to make 2 equations, one that represents the number of entries and the other that represents the money
x = child tickets
y = adult tickets
x + y = 132
x * $5.20 + y * $9.00 = $994.20
First we have to solve for the x in the first equation
x + y = 132
x = 132 - y
Now we replace the x with (132 - y) in the second equation
x * $5.20 + y * $9.00 = $994.20
(132 - y) * 5.20 + y * 9.00 = 994.20
686.4 - 5.2y + 9y = 994.2
-5.2y + 9y = 994.2 - 686.4
3.8y = 307.8
y = 307.8/3.8
y = 81
We replace y with its value in the first equation
x = 132 - y
x = 132 - 81
x = 51
That day 51 child tikets were sold
So the formula you have to do is A= (pie)(radius)(squared)
divide 6.7 by 2 to find the radius which is 3.35
now do 3.35 * 3.35 ( we are squaring it) which = 11.225
now 11.225 times PIE is 35.264377537
so the answer is 35.264377537
hope that helped!
