3 times a year for 2 years is equal to 3 x 2, or 6. So we know that she will have to pay her bill 6 times.
The cost for each trimester is $1450, but we still have to add the book costs ($350). So, 1450 + 350 = 1800.
Now we know that she has to pay $1800 six times. So the equation will be:
1800 x 6 = 10800.
It will cost Samantha $10,800 to get her degree.
I think you just add all the sides even the ones you don't see. The left side of the shape is 6m as well as the right. and the same with the 4s. The answer is 36.
14. 128
15.25
16.90
those should be right
Let the two numbers are x and y
Let larger number = x
and smaller number = y
it means
x-y = 0.77
Now it says larger number is increased 5 times
So it now becomes 5x
So second equation becomes
5x -y =77
Now we have to solve these two equations
x-y = 0.77 and 5x-y = 77
multiply first equation by -1 and then add both equations
-x+y = -0.77
Now on adding we get
-x+5x +y -y = 77-0.77
4x = 76.23
Divide both sides by 4
x=19.0575
We get the larger number , now subtract 0.77 from this , we will get the smaller number
y=19.0575-0.77=18.2875
y=18.2875
Hence the larger number = 19.0575
Smaller number = 18.2875
A² + b² = c²
Where a and b are the legs and c is the hypotenuse
So, plug in 10 for one of the legs and 24 for the other leg
c will be left blank because that is what you are trying to find, the hypotenuse
10² + 24² = c²
100 + 576 = c²
676 = c²
Take the square root of both sides of the equation to isolate c
√676 = √c²
Square of c and the square root cross out on the right
Take the square root of 676
c = 26
So, the length of the hypotenuse is 26 centimeters
