Answer:
127 inches
Step-by-step explanation:
A single yard is equal to 3 feet. So one yard 1 foot and 9 inches is:
and 9 inches.
each feet has 12 inches, so it goes something like this:
inches
multiply it out:
Thats the total number of inches, now we divide by 3 (use long division:
Hope this helps!
So, 10%-7%=3%=$294
$294/3%=$9800
Answer: The cost price of the necklace is $9800.
That would be a 120 Square Feet.
Use the length of one side of the ceiling, which is 12, and then use the other side that is 10. The ten feet comes from the floor. think of it in 2-Dimensional
Answer:
4r- 21
Step-by-step explanation:
4 - r= r and r+ 21/= R21 and Simplified Is -4 and R21
Remark
It's a right triangle so the Pythagorean Theorem applies. All you have to do is put the right things in the right places of the formula.
Givens
a = x
b = x + 4
c = 20
Formula and Substitution.
a^2 + b^2 = c^2
x^2 + (x + 4)^2 = 20^2
Solution
x^2 + x^2 + 8x + 16 = 20 Collect the like terms on the left.
2x^2 + 8x + 16 = 20 Subtract 20 from both sides.
2x^2 + 8x + 16 - 20 = 0
2x^2 + 8x - 4 = 0 Divide through by 2
x^2 + 4x - 2 = 0
Use the quadratic formula
a = 1
b = 4
c = - 2
From which x = (-4 +/- sqrt(24) ) / 2
x1 = (- 4 +/- sqrt(4*6) ) / 2
x1 = (- 4 +/- 2 sqrt(6) ) / 2
x1 = -2 + sqrt(6)
x2 = -2 - sqrt(6) This is an extraneous root. No line can be minus.
x1 = + 0.4495
x2 = x + 4 = 4.4495
