Answer:
7√2
Step-by-step explanation:
Thank to the give angle we can say that the two legs are congruent
b = 
98/2 = 49
49/7 = 7
7/7 = 1
98 = 7^2 x 2
√98 = 7√2
Answer:
It should be 905m3
Step-by-step explanation:
Result
Volume =
4 πr3
3
=
4 ×π×63
3
= 288π
= 904.77868423386 feet3
Even if it says feet, the measure doesn't really matter on this one.
Answer:
Options (3), (4) and (5)
Step-by-step explanation:
1). a² - 9a + 7ab + 63b
= a(a - 9) + 7b(a + 9)
Now we can not solve this problem further.
Therefore, can't be factored by grouping.
2). 3a + 4ab - b - 12
= a(3 + 4b) - 1(b - 12)
We can't solve it further.
Therefore, can't be factored by grouping.
3). ab + 6b - 2a - 12
= b(a + 6) - 2(a + 6)
= (b - 2)(a + 6)
We can be factored this expression by grouping.
4). x³ + 9x²+ 7x + 63
= x²(x + 9) + 7(x + 9)
= (x² + 7)(x + 9)
Therefore, the given expression can be factored by grouping.
5). ay² + a - y² - 1
= a(y² + 1) - 1(y² + 1)
= (a - 1)(y² + 1)
This expression can be factored by the grouping method.
Options (3), (4) and (5) are the correct answers.
Answer:
Yes because 1/2 is half of a circle and 3/6 is 3 of 6 of a colored circle to yes, it is equivalent.
