Answer:
Step-by-step explanation:
16(1/4)^2 - 4(6)
16(1/16) - 24
1 - 24 = -23
1. A. 550 meters.
this is because 2.5 km = 2500 meters, since there are 1000 meters in one kilometer.
therefore, 2500 - 1950 = 550 meters.
2. B. 126 inches.
this is because there are 12 inches in one foot, so we multiply 12 by 10 since there are 10 full feet. this leaves us with 120. then, we add half a foot, which is 6 inches. therefore, it is 126 :)
Answer:
Part A. ![\frac{84.3y}{12} = 7 +\frac{0.1\cdot y}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B84.3y%7D%7B12%7D%20%3D%207%20%2B%5Cfrac%7B0.1%5Ccdot%20y%7D%7B4%7D)
Part B. The correct quotient is (3 × 4)
Step-by-step explanation:
Part A.
To divide 84.36 by 12 we look for the Highest Common Factor of the whole number and the decimal portions of the numerator and the denominator individually as follows;
![\frac{84.36}{12} = \frac{84+0.3636}{12} = \frac{2 \times 2 \times 3 \times 7+0.01\times 12\times 3}{12} = \frac{12 \times 7+0.03\times 12}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B84.36%7D%7B12%7D%20%3D%20%5Cfrac%7B84%2B0.3636%7D%7B12%7D%20%20%3D%20%20%5Cfrac%7B2%20%5Ctimes%202%20%5Ctimes%203%20%20%5Ctimes%207%2B0.01%5Ctimes%2012%5Ctimes%203%7D%7B12%7D%20%3D%20%20%5Cfrac%7B12%20%20%5Ctimes%207%2B0.03%5Ctimes%2012%7D%7B12%7D)
Therefore, dividing 84.36 by 12 gives
= 7.03
When dividing 84.3·y by 12, therefore, we have;
![\frac{12 \times 7+0.3\times y}{12} = 7 +\frac{0.1\cdot y}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B12%20%20%5Ctimes%207%2B0.3%5Ctimes%20y%7D%7B12%7D%20%3D%207%20%2B%5Cfrac%7B0.1%5Ccdot%20y%7D%7B4%7D)
Part B.
The correct quotient should have factors of the numerator
Therefore the divisor 12 should be represented as follows
![\frac{12 \times 7+0.3\times y}{12} =\frac{12 \times 7+0.3\times y}{3 \times 4}](https://tex.z-dn.net/?f=%5Cfrac%7B12%20%20%5Ctimes%207%2B0.3%5Ctimes%20y%7D%7B12%7D%20%3D%5Cfrac%7B12%20%20%5Ctimes%207%2B0.3%5Ctimes%20y%7D%7B3%20%5Ctimes%204%7D)
The correct quotient therefore = (3 × 4)
