We can't tell. Any certain letter doesn't have to mean the same thing wherever you see it. You can use any letter you want to represent any quantity you want when you write an expression or a formula, as long as you clearly tell what it stands for.
C = 2r This could mean anything.
It could mean that Julie has a great many pets. For every rat she has,
she also has two cats. Write a formula that tells how many cats she
needs for 16 rats.
It could mean that the Circumference of a circle is equal to 2 times
the length of the circle's radius.
It could mean that Rocko is baking oatmeal-raisin cookies. He is
cutting each raisin in half, and putting 1/2 of one raisin in each cookie.
Write a formula that tells how many cookies he can make with 16 raisins.
So if 6 out of 40 are incorrect, 40-6= 36 must be correct.
In order to gain percentage you do proportions.
36/40 = x/100.
Multiply 36 times 100 then divide by 40, which is 90.
The answer is 90%.
90% of the questions he got were correct.
Slope is 1.3
take your 2 points and make a triangle, then count the small boxes to the point in the middle where they met. ( REMEMBER THE X&Y RULES)
you should get 4/3, you need to divide and put it into decimal form.
GOOD LUCK! :))
hey, please be more descriptive or be in detail for your answer to get properly answered. Have a good day!
