The display got this answer because you forgot to put the decimal point on 42.8 and typed in 428 instead this is why the display shows the wrong answer. You can estimate the answer by seeing the numbers are really low and the answer can’t be that big.
Answer:
358.01
Step-by-step explanation:
3 x 10^2 +5 x 10^1 +8 x 10^0 +1 x 1/10^2
3 x 100 + 5 x 10 +8 x 1 +1 x 1/100
300 +5 x 10 +8 x1 +1 x 1/100
300 + 50 +8 x1 +1 x 1/100
300 +50 +8 +1 x1/100
300 +50 +8 +1/100
358 +1/100
35801/100
358.01
7 because there are 15 fruit in total but only 7 of them are apples
For this case we can make the following rule of three:
1507 ----> 100%
1213 ----> x
Clearing the value of x we have:
x = (1213/1507) * (100)
x = 80.4910418
Rounding off we have:
x = 80.5%
Answer:
this player has made 80.5% of free throws
Answer:
PEMDAS is a great way to figure this out!
P - Parenthesies
E - Exponents
M - Multiplcation
D - Division
A - Addition
S - Subtraction
Follow this order and you should be good to go! Here's how I would follow this in this equation.
11x-2-3(1-7x)^2+(x+1)
First, parentheses
The 3 directly next to the parenthesies shows that everything inside of the () needs to be multiplied by 3.
-3*1 and -3*-7x (don't forget the negative)
This gives us 11x-2+(-3+21x)^2+(x+1)
Now distribute the exponents to everything inside of the parentheses.
11x-2+-3^2+21x^2+(x+1)
now solve the numbers with exponents without a variable.
3^2 = 3*3 = 9
combine any numbers without a variable outside of parentheses
11x-2+9+21x^2+(x+1)
11x+7+21x^2+(x+1)
From here, what I would do is divide the whole equation by 2
5.5x+3.5+21x+(.5x+.5)
now combine x values outside of parentheses
3.5+26.5x+(.5x+.5)
I believe this would be the simplest form, but please do correct me if I'm wrong or made any errors
