Answer:
33
Step-by-step explanation:
3 plus 5 = 8
8 plus 9 = 17
17 plus 7 = 24
24 plus 9 = 33
this is just a multistep problem,
Hope this helps!
For y=x^2-6x-11
complete the square
so roots
set y=0
0=x^2-6x-11
group x terms
0=(x^2-6x)-11
take 1/2 of linear coefient (-6) and square it
-6/2=-3, (-3)^2=9
add positive and neative to inside of parenthasees
0=(x^2-6x+9-9)-11
complete square
0=((x-3)^2-9)-11
expand
0=(x-3)^2-9-11
0=(x-3)^2-20
add 20 to both sides
20=(x-3)^2
sqrt both sides
remember positive and negative roots
+/-2√5=x-3
add 3 to both sides
3+/-2√5=x
so
x=3+2√5 and 3-2√5
Given:
Chung has 6 trucks and 5 cars in his toy box.
Brian has 4 trucks and 5 cars in his toy box.
To find:
The correct comparison of their ratios of trucks to cars.
Solution:
The ratio of trucks to cars is defined as:
Chung has 6 trucks and 5 cars in his toy box. So, the ratio of trucks to cars is:
Brian has 4 trucks and 5 cars in his toy box.
We know that,
Therefore, the correct option is D.
20 nickels =1.00
4 quarters = 1.00
20:4
simplify. divide by 4
5:1
answer is C
Here is the one conversion we need to know:
1 yard = 3 feet
So we can now create a fraction to show what 26 feet is in yards:
26 / 3
The answer is in mixed numbers, though, so we need to convert 26/3 into a mixed number:
3 goes into 26 eight full times (3 x 8 = 24), leaving 2 left before you get to 26. So the mixed number is 8 2/3, so B is the correct answer.
