Answer:
the value of x is 17 cm
Step-by-step explanation:
The computation of x is shown below:
Here we applied the pythagoreans theorem
x^2 = a^2 + b^2
x^2 = 15^2 + 8^2
X^2 = 225 + 64
x^2 = 289
x = sqrt(289)
= 17
Hence, the value of x is 17 cm
Answer:
$525
Step-by-step explanation:
using the formula given to find the amount after 1 year
i=500*.05*1
i=25
25+500=525
Answer:
56
Step-by-step explanation:
Basically, 3 x 8 is equal to 24, and Zoe recieved £24. So, if 24/3 is equal to 8, and 3 x 8 is equal to 24, 7 x 8 is equal to 56, by checking, 56/8 is equal to 7.
Answer:
see explanation
Step-by-step explanation:
Given that z varies directly with y and x then the equation relating them is
z = kxy ← k is the constant of variation
To find k use the condition x = 6, y = 12 and z = 10
k = = = = , hence
z = xy ← equation of variation
