At one point during the hike, Noe is at an elevation of 453 feet. After descending at a rate of 50 feet per
minute, she reaches an elevation of 146 feet.
How long does the descent take?

Answers

Answer:

6.14 minutes   or   6 minutes & 8.4 seconds

Step-by-step explanation:

Initial elevation: 453 ft

Final elevation: 146 ft

Difference in elevation: 453 ft - 146 ft = 307 ft

speed = 50 ft/min

speed = distance/time

time * speed = distance

time = distance/speed

time = (307 ft)/(50 ft/min)

time = 6.14 minutes = 6 minutes + 0.14 * 60 seconds

time = 6.14 minutes = 6 minutes + 8.4 seconds

It was estimated that 650 people would attend bowling night, but 676 people actually attended.
What is the percent error, to the nearest percent of the estimate? Enter the answer in the box.

Answers

Simply divide 650/676=.9615 or 96.15%. So there was 3.85% error

The estimate's percent error is 4%, to the closest percentage.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Find the difference between the estimate and the actual value:

Actual value - Estimated value = 676 - 650 = 26

The absolute value of the difference is 26, indicating that the actual value exceeded the estimated value.

Next, we need to find the relative error, which is the difference divided by the estimated value:

Relative error = Difference / Estimated value = 26 / 650

Finally, we can convert the relative error to a percentage by multiplying it by 100:

Percent error = Relative error x 100 = 26 / 650 x 100 ≈ 4

Therefore, the percent error, to the nearest percent, of the estimate is 4%.

Please Help. Lateena solved the equation below. Is her solution correct? Explain why or why not?
I've attached the picture for the problem.

Answers

Answer:

Not correct

Step-by-step explanation:

Given:

x² - 6x - 7 = 0

The following equation can be solved correctly by factoring Thus,

x² - x + 7x - 7 = 0

x(x - 1) +7(x - 1) = 0

(x - 1)(x + 7) = 0

(x - 1) = 0

x - 1 = 0

x - 1 + 1 = 0 + 1

x = 1

Or

(x + 7) = 0

x + 7 = 0

x + 7 - 7 = 0 - 7

x = -7

Therefore, the solution would be x = 1 or x = -7

Lateena solution is therefore NOT CORRECT because she used a wrong method.

(Site 1) I need help ill give brainliest NO LINKS PLEASE HELLPPPP!!!!! Our highways, espressways, and streets become increasingly congested every day as our population increases and more new drivers enter the road. Distracted driving isn't justa problem for teenagers; it's also a problem for adults. However, today's problems are not the same as they once were. We now have laws prohibiting texting while driving, as well as statistics on the number of people who die as a result of texting while driving. Because of texting and driving, the number of people killed in car accidents has risen. People are nowengrossed in their modern gadgets such as phones, iPods, and other similar devices, rather than wasting time trying to locate a station on the radio. Texting while driving continues to be one of today's most serious distractions for drivers.Florida has enacted legislationprohibiting it, but the penalty is just $30. Although it was formerly a secondary offense and is now a $30 fine, I believe it should be increased. A teens's license can indeed be strippedaway if they are found testing and driving.If an adult is caught, I believe their driver'slicense should be revoked. If all you have to do is pay a thirty-dollar fee then that won't get anyone to stop distracted drivers. We need to do something to grab their attention more than their phones do In the year 2013, the state of Florida enacted legislation prohibiting texting while driving. Even though the legislation was passed, it stipulates that in order to be prosecuted for this crime and fined the $30, you must commit two crimes, which has sparked concerns among citizens about the law's effectiveness.Some residents were concerned that otherresidents (mostly teens and other young and reckless drivers) would be resistant to the new legislation. Furthermore, some residents may live in fear of someone violating the law, resulting in an accident, and innocent people dying as a result of a simple text message thatshould have been delayed. The issue is that some residents want to establish a more updated and stricter regulation, which is understandable, but Florida is currently doing the best itcan to help discourage texting and driving Forty-two states, which include Florida, have declared texting while driving illegal. These states, have taken steps to improve the way they are by making the amount of injuries less than they were in the state. As a result, this bright sunshine state will be able to provide highways with drivers who will not damage their surroundings. It's believed that people want a much better rule, but Florida is still working to make this wish a reality for residents. The feelings of the citizens about making this rule, or even a more powerful law, are reciprocal or much stronger.Can someone write at lest a 5 sentence conclusion for the writing above??
