Answer:
Step-by-step explanation:
You can use the Pythagorean Theorem to find the length of the third side AB (Identified as "x" in the figure attached in the problem), which says that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the legs:
a² = b²+c²
As we can see the figure, the triangle does not have an angle of 90°, but it can be divided into two equal parts, leaving two triangles with a right angle. We already have the values of the hypotenuse and a leg in triangle "A" , so we can find the value of the other leg:
b = √(a²-c²) b = √(10²-4²) b = 9.16
With these values, we can find the hypotenuse in the triangle "B": x = √b²+c² x = √(9.16)²+(4)² x = 10
( 2 1 / 4 ) * ( 5 / 3 ) = ( 9 / 4 ) * ( 5 / 3 ) = 45 / 12 = 15 / 4 = 3.75 mile run in an hour
Answer: 36
Step-by-step explanation:
1.) You divide 180 by 20 to find out how many gallons their are
180÷20= 9
2.) Now you multiply the 9 by the cost of each gallon, which is $3.98
9×3.98= 35.82
3.) 35.82 is rounded to $36
