The total cost is 15.75
explanation: 5 percent of 15 is .75 plus the initial cost of 15 equals 15.75
The area of triangle is 7 square units, which is mentioned in option B. It is obtained from the given diagram.
Step-by-step explanation:
The given is,
For above question diagram is missing, so i attach the diagram.
Step:1
Formula for area of triangle from the coordinates,
.............(1)
Where,
are coordinates
From the given,
A ( 1, 1 ) - ![(x_{1} , y_{1} )](https://tex.z-dn.net/?f=%28x_%7B1%7D%20%2C%20y_%7B1%7D%20%29)
B ( 4, 0 ) - ![(x_{2} , y_{2} )](https://tex.z-dn.net/?f=%28x_%7B2%7D%20%2C%20y_%7B2%7D%20%29)
C ( 3, 5 ) - ![(x_{3} , y_{3} )](https://tex.z-dn.net/?f=%28x_%7B3%7D%20%2C%20y_%7B3%7D%20%29)
Equation (1) becomes,
Area, ![A = \frac{1}{2} [1(0-5)+4(5-1)+3(1-0)]](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5B1%280-5%29%2B4%285-1%29%2B3%281-0%29%5D)
![= \frac{1}{2} [1(-5)+4(4)+3(1)]](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5B1%28-5%29%2B4%284%29%2B3%281%29%5D)
![= \frac{1}{2} [ -5 +16 + 3]](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5B%20-5%20%2B16%20%2B%203%5D)
![= \frac{1}{2} (14)](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2814%29)
= 7
Area of triangle, A = 7 square units
Result:
The area of triangle is 7 square units, which is mentioned in option B. It is obtained from the given diagram.
Answer:
Only 10 base units to learn
Step-by-step explanation:
The metric system is a decimal based system developed to be universally acceptable by making use of base units from obtained from nature and the use of prefixes for multiples and submultiples of the base units, decimal ratios, which allows easy representation of quantities, as well as having a coherent structure of base and derived units which are obtained from the base units
During conversion in the metric system, which is decimal based, it is only required to move the decimal point
The prefixes which are used to specify multiples and submultiples are the same through out
The decimal system is based on the powers of ten
The number of base units to learn are 7 including; 1. Meter (m), 2. Kilogram (kg), 3. Second (s), 4. Ampere (A), 5. Kelvin (k), 6. Candela (cd), and 7. mole (mol)
Therefore the metric system has several advantages that include all of the following except; Only 10 base units to learn
Anything withdrawn you subtract. Then, you know the total and you know what you had. Subtract total from what you had and you will see the change.
1735.97-100=1635.97
1668.71-1635.97=32.74
Answer:
