Jayden is driving 390 miles to visit the Gateway Arch in St. Louis. He drives at an average rate of 65 miles per hour. Explain how you can find the amount of time it will take her to get to the arch

Answers

Using the relation between velocity, distance and time, it is found that it will take her 6 hours to get to the arch.

What is the relation between velocity, distance and time?

Velocity is distance divided by time, that is:

v = d/t.

For this problem, we have that:

She drives 390 miles, hence d = 390.Her velocity is of 65 miles per hour, hence v = 65.

We can solve the equation for t to find the time, hence:

65 = 390/t

65t = 390

t = 390/65

t = 6.

It will take her 6 hours to get to the arch.

~Direct Variation When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation. In simpler terms, that means if A is always twice as much as B, then they directly vary. If a gallon of milk costs $3, and I buy 1 gallon, the total cost is $3.~

When Brandon went bowling, it cost $4.95 per game, plus a one-time fee to rent the shoes. Brandon played 5 games and paid $32. Write and solve a linear equation to find the cost to rent the shoes. Enter just the equation in slope-intercept form on this question.


Use the equation from the previous question to find the cost of renting the shoes.​

Answers

Answer:

$7.25.

Step-by-step explanation:

Given that, when Brandon went bowling, it cost $ 4.95 per game, plus a one-time fee to rent the shoes, and knowing that Brandon played 5 games and paid $ 32, to find the cost to rent the shoes the following equation must be performed :

4.95 x 5 + X = 32

24.75 + X = 32

X = 32 - 24.75

X = 7.25

Thus, the cost of renting the shoes was $ 7.25.

An article claimed that only 38\88, percent of hotel visitors used the alarm clock provided. A hotel manager wanted to see whether that proportion applied to the hotel where she worked, so she took a random sample of 700700700 of the approximately 10{,}00010,00010, comma, 000 visitors to the hotel one month and checked whether they used their room alarm clock. Of the sampled visitors, only 35\55, percent used the alarm clock. Assuming that the article's 38\88, percent claim is also the true proportion for visitors to the hotel, what is the approximate probability that less than 35\55, percent of the sample used the alarm clock

Answers

Answer: P(p<0.35) = 0.05

Step-by-step explanation:

Khan told me

The approximate probability that less than 355 of the same used the alarm clock will be equal to 0.0485.

What is Probability?

Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.

As per the given information given in the question,

P = 0.38

Q = 1 - P = 1 - 0.38 = 0.62

n = 700 and sample proportion, p = 0.35

Use the formula given below,

z = (p - P)/√(PQ/n)

z = (0.35 - 0.38)/√(0.38 × 0.62)/700

z = -0.03/0.018

z = -1.666

Now,

For P(X < 35%) = P(Z < -1.66)

= P(-∞ < Z < 0) - P(-1.66 < Z < 0)

= 0.5 - 0.4515 = 0.0485

Here are the ingredients needed to make 8 pancakes
250ml milk
140 g flour
5 g butter
a) Simon makes 4 pancakes.

Answers

Answer: To make 4 pancakes, Simon will need 125 ml milk, 70 grams flour, and 2.5 grams of butter.

Step-by-step explanation:

If that is the recipe to make 8 pancakes, and Simon has 4 pancakes, then Simon needs to cut the recipe in half. So we can multiply each ingredient by 1/2.

250 x 1/2 = 125.

140 x 1/2 = 70.

5 x 1/2 = 2.5

In conclusion, to make 4 pancakes, Simon will need 125 ml milk, 70 grams of flour, and 2.5 grams of butter.
