(7+6) + 9. That is the correct answer
Answer:3 17/24 feet
2 3/8+1 1/3=3 17/24
Step-by-step explanation:
The dragonfly traveled a distance of 87.5 miles at a rate of 35 miles per hour.
Explanation:
Distance traveled by butterfly at the rate of 34 miles per hour in 2.5 hours
=35 mi/hr × 2.5 hour
=<span><span>35mi</span><span>hour</span></span> ×2.5 <span>hour</span>
=<span>35mi⋅<span>2.51</span>⋅<span>1010</span></span>
=<span>35mi⋅<span>2510</span></span>
=<span>35mi⋅<span>52</span></span>
=<span>175m<span>i2</span></span>
=<span>87.5mi</span>
∴ It would travel a distance of 87.5 miles.
Here mi represents miles.
The answer is hollow sphere
Answer:
6 ounces
Step-by-step explanation:
Let x = the number of ounces of the 15% alcohol solution needed to be mixed with the 4 ounces of 20% alcohol solution to obtain the 17% alcohol solution.
After converting the percentages to their decimal equivalents, set up the necessary equation as follows:
0.15x+0.20(4) = (x+4)(0.17) Simplify and solve for x.
0.15x+0.8 = 0.17x+0.68 Subtract 0.15x from both sides.
0.8 = 0.02x+0.68 Now subtract 0.68 from both sides.
0.12 = 0.02x Finally, divide both sides by 0.02
x = 6
You need to mix 6 ounces of 15% alcohol solution with 4 ounces of 20% alcohol solution to obtain 10 (x+4)ounces of 17% alcohol solution.
