Answer:
781/1680
Step-by-step explanation:
Don't you have a calculator?
I assume that by (1 2/3 1/9), you mean (1+2/3)*(1/9)
Assuming that you put all necessary parentheses:
781/1680, approx. 0.4648809523809524
Answer:
Dividing a whole number by a fraction you would just multiply the bottom number of the fraction by the whole number.
Step-by-step explanation:
(here is how to divide a fraction by a whole number, if you need help on that also.)
1. Turn the whole number into a fraction. ( ex: 2=2/1)
2. Multiply the fraction by the whole number fraction.
3. Multiply the tops together and the bottoms together
Dividing A Fraction By A Fraction
1. Arrange the equation
2. Keep the first fraction
3. Change the sign
4. flip the fraction
5. Multiply the tops together and the bottoms together
Answer:
-11 =x
Step-by-step explanation:
-1 = (5+x) /6
multiply by 6
-6 = 5+x
-11= x
Answer:
$ 327.08
Step-by-step explanation:
Let x = width of the container,
Then Length of the container = 2x
Let h = height of the container,
volume of the container can be calculated as length × width × height
= 2x × x × h
= 2x² h
Then we can say Volume =
= 2x² h=10
If we simplify inorder to get h
We have h= 5/x²
Then the area= (2L×h) +(2xh)
Where L is lenght
x= wish
h= height
= 2× 2x × h+ x× h
= 4x× 5/x + 2x × 5/x
Area = 30/x
Now, the area of the base = length × width
But from question, for the base costs $20 per square meter. Material for the sides costs $12 per square meter
Then the cost C(x)= 2x²× 20+30/x ×12
C(x)= 40x²+35/x²
If we differenciate wrt x we have
C(x)= 80-360/x²
If we equate C(x)=0the
80=360/x²
x= 1.651
If substitute to C(x)= 40x²+35/x²
C(x) = 40(1.651)² + 35/(1.651)²
We have cost= 327.08
Answer:
P(both are red) = 5/18
Step-by-step explanation:
total counters = 9
red counters = 5
P(both red) = P(R1) n P(R2)
5/9 * 4/8 =5/18
5/9 because the red counters are 5 and the total number of counters are 9.
I multiplied by 4/8 because, after selecting the first red counter without replacement, the remaining is 4 and the total decreases to 8.
