Answer:
B= 6
Step-by-step explanation:
pythagorean theorem formula is a² + b² = c²
so: 8² + b² = 10²
then: 64 + b² = 100
subtract 64 from both sides to get b²= 36
square root 36 and you get 6 for b
answer: B= 6
Answer: 96 cups
Step-by-step explanation: A gallon holds 128 ounces there were 6 gallons used to make the punch. 128x6= 768 ounces
A cup holds 8 ounces so you would do 768/8 and that would give you 96 cups
Answer:
D is correct
Step-by-step explanation:
A graph of that sort will make a perfectly mirrored "V" shape, and with no offset, the bottom point will be on the y axis. This means that the first equation will intercept the y axis at zero, the second will intercept the y-axis at -15.
"A" may seem correct also, as the second graph will intercept the x-axis at -15, but it is not complete, as it will intercept that axis at +15 as well.
Since the train travels at a rate of 70 miles/hour, the train will take 5 hours to have traveled a total of 350 miles. The missing information in the question you've proposed is the value of "H" or the number of hours (as the unit hours is indicated in the question). This can be determined with the formula <em>Distance = rate X time. </em>350 = 70 X H, in this case. To isolate the variable H, 70 (the rate) divides 350 (the total distance) into 5. 350 ÷ 70 = H. 5 = H, the amount of time spent traveling for 350 miles at a rate of 70 miles/hour.
