Write the decimal number as a fraction
(over 1)
19.79 = 19.79 / 1
Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's
Numerator = 19.79 × 10 × 10 = 1979
Denominator = 1 × 10 × 10 = 100
Numerator / Denominator = 1979 / 100
Simplifying our fraction
= 1979/100
= 1979/100
= 19 79/100
Answer:
36/4
simplified 9/1
Step-by-step explanation:
You foil for this one so it means that you multiply -3 with g, then multiply -3 with -f, you should get -3g+3f, but i'm not sure if i did it correctly if i did get it wrong then my bad
Answer:
a. 6 feet
b. The length of the angle bisector of angle A is approximately 7.81 feet
Step-by-step explanation:
a. The given parameters of the right triangle ABC are;
The length of the leg AC = 5 ft.
The length of the hypotenuse AB = 13 ft.
Therefore, the length of the side BC = √((AB)² - (AC)²) = √((13 ft.²) - (5 ft.²)) = 12 ft.
The length to the middle of the side BC = BC/2 = (12 ft.)/2 = 6 ft.
b. The length of the angle bisector of angle A = The the length of the median from A to the side BC = √((BC)/2)² + (AC)²)
BC = √(((12 ft.)/2)² + (5 ft.)²) = √61 ft. ≈ 7.81 ft.
