Answer: C. 5.8 inches
Step-by-step explanation:
The formula for calculating the Surface area of a cube is give as :
surface area = 6
Where a is the length of an edge
That is :
200 = 6
divide through by 6
200/6 =
that is
= 33.33333333
take the square root of both sides
a = 5.773502692
Therefore the length of an edge ≈ 5.8 inches
Answer:
2520 ways
Step-by-step explanation:
We can solve this problem with 3 combinations:
First the teacher needs to give 3 fruit snacks to 10 students, so we have a combination of 10 choose 3: C(10,3) = 10! / (3! * 7!) = 120
Then, she needs to give 2 teddy grahams to 7 students (3 already got a snack), so a combination of 7 choose 2: C(7,2) = 7! / (2! * 5!) = 21
The, she gives the 5 granola bars to the other 5 students, so a combination of 5 choose 5: C(5,5) = 1.
Now we just need to multiply the combinations to find the result:
C(10,3) * C(7,2) * C(5,5) = 120 * 21 * 1 = 2520 ways
<span>perimeter = 2(a +b), where a = length and b = width
p = 68
a+b = 34
so
a = 34-b
.
diagonal = c = 26 cm
.
Pythagorean Theorem teaches us that:
.
c^2 = a^2 + b^2
.
Substitute for a = 34-b and c = 26
.
26^2 = (34-b)^2 + b^2
,
Collect terms.
.
676 = (b^2 -68b + 1156) + b^2
.
2b^2 -68b + 480 = 0
.
b^2 -34b +240 = 0</span>
Answer:
12
Step-by-step explanation:
When we divide fractions we multiply instead since it's the opposite of division and we do the reciprocal. Reciprocal means we flip the fraction from 1/3 to 3/1
So:
4÷1/3 would become 4×3/1
4×3/1 is the same as 4×3
So:
4×3=12
That's why the answer is 12.
Answer:
3/7 - 1/12 is equal to 29/84, which is less than 1/2, so no, it is not greater than 1/2.
