Answer: it took them 7 hours to travel 49 miles.
Step-by-step explanation:
The exploratory scouts travel 32 miles in eight hours.
Speed = distance/time
It means that the speed at which they travelled 32 miles is
32/8 = 4 miles per hour.
The next day they had traveled 49 miles so they increase the speed by 3 mph. It means that the speed at which they travelled 49 miles is
4 + 3 = 7 mph
Time = distance/speed
Therefore, the time it took them to travel the 49 miles is
49/7 = 7 hours
Answer:
6.6%
Step-by-step explanation:
First turn 6 3/5 into a improper fraction (33/5). Then divide 33 by 5 which gives you the percent (6.6)
Answer:
Step-by-step explanation:
The area of a circle is found using this formula:
We know the circle's diameter is 5 feet, but we don't know the radius. Remember the diameter passes through the center from one side to the other, while the radius connects the center and the side. Therefore, the radius is half the diameter.
We know the radius is 2.5 feet and we are using 3.14 for pi. Substitute the values into the formula.
Solve the exponent.
- (2.5 ft)²= 2.5 ft *2.5 ft=6.25 ft²
Multiply.
The area of the circle is <u>19.625 square feet.</u>
Let's solve your equation step-by-step.
<span><span><span><span>3v</span>+9</span>−<span>8v</span></span>=<span>−31
</span></span>Step 1: Simplify both sides of the equation.
<span><span><span>−<span>5v</span></span>+9</span>=<span>−31
</span></span>Step 2: Subtract 9 from both sides.
<span><span><span><span>−<span>5v</span></span>+9</span>−9</span>=<span><span>−31</span>−9</span></span><span><span>−<span>5v</span></span>=<span>−40
</span></span>Step 3: Divide both sides by -5.
<span><span><span>−<span>5v</span></span><span>−5</span></span>=<span><span>−40</span><span>−5
</span></span></span><span>v=<span>8</span></span>
Answer:
5 3/5 is already a mixed number
3 4/9 is also already a mixed number
43/9 = 36/9 + 7/9 = 4 7/9
32/5 = 30/5 + 2/5 = 6 2/5
