Answer:
the answer is 5.8
Step-by-step explanation:
divide numerator (8) by the denominator (10):
8 / 10 = 0.8
add this value to the integer part: 5 + 0.8 =
5.8 So,
5 8/10 = 5.8
Answer:
Kevin's estimate is incorrect. When x=4, the value of y is $116, which is not close to
$180.
Step-by-step explanation:
I'm pretty sure you are looking for factored forms as an equivalent equation, so here is how you do it.
This equation would be solved by difference of squares. 16, x^4, and 81 are all perfect squares ( which means that it is a number multiplied by itself, 16 is 4 x4 for example). So the first thing you want to do is recall the formula which is
(a^2 - b^2) = (a - b)*(a + b)
(16x^4 - 81)= 0
Find the sq. root of 16 which is 4, and of x^4 which is x^2, and 81 which is 9. Now re write it in the (a - b)*(a + b) format. ----> (4x^2 - 9)*(4x^2 + 9) = 0
Answer:
Ball Bearing Volume = (4 / 3) * PI * radius ^3
Volume = (4 / 3) * 3.14159265 * (.35)^3
Volume = (4 / 3) * 3.14159265 * 0.042875
Volume = 0.17959438 cc
1 cc of steel = 7.8 g
Volume of 1 kg of steel = 1,000 cc / 7.8 g per cc
1 kg = 128.205 cc
Number of ball bearings we can make = 128.205 / 0.17959438
Equals 713.86

Answer:
no
Step-by-step explanation:
to be a right triangle the smaller two sides squared & added together would equal the square of the longer side
does 5² + 6² = 8²?
25 + 36 = 61, not 64 so it is not a right triangle
