We will use the Unitary method to solve this question
304/4=76
Therefore The train travels 76 miles per hour
76*7.5=570
Therefore the train travels 570 miles in 7.5 hours
Answer:
25.6 feet to the nearest tenth.
Step-by-step explanation:
The fallen tree and the ground make a right-angled triangle with the side opposite the 40 degree angle = 10 ft and the hypotenuse is the length of the tree above 10 ft.
So sin 40° = 10 / x where x is the hypotenuse.
x = 10 / sin 40°
x = 15.56 ft
So the height of the tree was 10 + 15.56 = 25.56 feet (answer).
Answer:
c < 32/27
Step-by-step explanation:
−7−5(−4c+4)<−7c+8−3
Step 1: Simplify both sides of the inequality.
20c−27<−7c+5
Step 2: Add 7c to both sides.
20c−27+7c<−7c+5+7c
27c−27<5
Step 3: Add 27 to both sides.
27c−27+27<5+27
27c<32
Step 4: Divide both sides by 27.
27c/27 < 32/27
c < 32/27
