In order to figure this out you can divide 9 3/4 and 1/4 because you want to know how many sets of 1/4 fits into 9 3/4.
9 3/4 ÷ 1/4 = 9 3/4 · 4 = 39/4 · 4 = 39
SO the answer is 39.
He Needs 3 More Inches Because 16 Feet Converted Into Inches Is 192 Inches. If You Do 192 - 189 You Have 3 Left Over. Therefore He Needs 3 More Inches To Pull Vault Over A Bar That Is 16 Feet High
I know of two ways to solve quadratic equations. The first is through factoring. Let us take the example (x^2)+2x+1=0. We can factor this equation out and the factors would be (x+1)(x+1)=0. To solve for the roots, we equate each factor to 0, that is
x+1=0; x+1=0
In this case, the factors are the same so the root of the equation is
x=1.
The other way is to use the quadratic formula. The quadratic formula is given as [-b(+-)sqrt(b^2-4ac)]/2a where, using our sample equation above, a=1, b=2 and c=1. Substitute these to the formula, and you will get the same answer as the method above.
Answer:
126
Step-by-step explanation:
the number of cargo cars is represented by the 35 part of the ratio , then
105 ÷ 35 = 3 ← value of 1 part of the ratio , then
passenger cars = 7 × 3 = 21
total cars = 105 + 21 = 126
