Answer:
40 feet
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as isosceles triangle, equilateral triangle, scalene triangle, right angled triangle.
The area of triangle ABC is given as:
Area = (1/2) * AC * BC * sin(C)
But C = 50°, Area = 65.1 ft², BC = 10 ft, AC = b, AB = 13 feet.
Substituting gives:
65.1 = (1/2) * b * 10 * sin(50)
3.83b = 65.1
b = 17 ft
Perimeter of ΔABC = AB + AC + BC = 17 + 13 + 10
Perimeter of ΔABC = 40 feet
Answer:
1 1/10
Step-by-step explanation:
2 1/5= 2 2/10
33/10- 22/10= 11/10 or 1 1/10 or 1.1
BTW you can use google!
Answer:
It depends on what digits repeat
Step-by-step explanation:
A decimal with repeating digits after the decimal point can be converted to a fraction depending on the digits after the decimal point.
For example, let’s have 4/3
When we evaluate this using a calculator, we can see that we have recurring 3 after the decimal point
So 4/3 is actually 1.3333333333333
We can see that based on the number after the decimal point we can convert this to 4/3
I say that it was 15 hours later. Because when he left the first hose in the pool at a rate of 5gph, after 10 hours it was filled with 50 gallons. But with the animals drinking from it the rte drops to 3gph. After 5 hours the pool is filled up with 65 gallons. And when the second hose is added the rate is bumped up to 7gph. And 35 gallons is ll that's left needed to fill the pool, so add 5 more hours to the 10 it took to fill the pool up with 35 more gallons of water.
