Answer would be 81.
you multiply 3 x 10 x 3, which is 90. then subtract 9 from that and you end up with 81
If i did the math right it would be (C)
Answer:
the fifth number is 11
Step-by-step explanation:
8,11,13 and 17, x
the mean is =12 ( which means the sum of the terms divided by the numbers of terms )
to find the mean :
(8+11+13+17+x)/5 =12
5*12=49+x
60-49=x
x=11
Answer:
<h2>x = 7</h2>
Step-by-step explanation:
The largest number is 5. Therefore x ≥ 6.
Convert numbers from x system to decimal system:
Solve the equation for x:
Answer:
10 sqrt(269) = c
164.0121947 = c
Step-by-step explanation:
The diagonal is the hypotenuse of the right triangle
The length and width are the legs of the right triangle
We can use the Pythagorean theorem
a^2 + b^2 =c^2
100^2 + 130^2 = c^2
10000+16900 = c^2
26900 = c^2
Take the square root of each side
sqrt(26900) = sqrt(c^2)
sqrt( 269) sqrt(100) = c
10 sqrt(269) = c
164.0121947 = c
