Answer: 140 miles

Step-by-step explanation:

35 mph

4 hours

35 x 4 = 140 miles

Answer:

Let the first term and the common difference of the A.P are a and d respectively.

Since the A.P contains 37 terms. So, the middle most term is (37+1)/2 th term = 19th term.

Thus, three middle most terms of this A.P.are 18th, 19th and 20th terms.

Given a 18 + a 19 + a 20 = 225

⇒ (a + 17d) + (a + 18d) + (a + 19d) = 225

⇒ 3(a + 18d) = 225

⇒ a + 18d = 75

⇒ a = 75 – 18d … (1)

According to given information

a 35 + a 36 + a 37 = 429

⇒ (a + 34d) + (a + 35d) + (a + 36d) = 429

⇒ 3(a + 35d) = 429

⇒ (75 – 18d) + 35d = 143

⇒ 17d = 143 – 75 = 68

⇒ d = 4

Substituting the value of d in equation (1), it is obtained

a = 75 – 18 × 4 = 3

Thus, the A.P. is 3, 7, 11, 15 …

289 196 248 379 319 276 198 349

(in order) 196, 198, 248, 276, 289, 319, 349, 379  there are eight numbers.

--------------------------------------------------------------------------------------

196, 198, 248, 276

since the median is between 198 and 248, we must add both numbers together and divide them by two:

(198 + 248) ÷ 2

= 446/2

--------------------------------------------------------------------------------------

289, 319, 349, 379

since the median is between 319 and 349, we must add both numbers together and divide them by two:

(319 + 349) ÷ 2

= 668/2

Answer:

Step-by-step explanation:

Don't use 0 (or any other number) to replace θ. Use a letter variable such as x.

tan(x) = 7/24

sin(x)/cos(x) = 7/24

sin(x) = 7/√(7²+24²) = 7/√625 = 7/25

Step-by-step explanation:

P=11.25

Answer:

Step-by-step explanation:

25% of a hundred is one-fourth and because there are six students in a fourth of the whole we are multiplying four and six. 6x 4 is 24.

The percentage is calculated by dividing the required value by the total

value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

25% = 6 students

100% = 24 students

The total number of students in Mr. Foster's class is 24.

The percentage is calculated by dividing the required value by the total

value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of students who chose an amber background = 6

25% of Mr. Foster's class chose an amber background for their school picture.

This means,

25% = 6

The total number of students = 100%

Now,

25% = 6 students

Multiply 4 on both sides.

4 x 25% = 4 x 6 students

100% = 24 students

Thus,

The total number of students in Mr. Foster's class is 24.

Answer:

West.

Step-by-step explanation:

An old treasure map has the following instructions: stand next to the black rock and face west. Walk 20 yards and then turn 90 degrees clockwise. Walk another 10 yards and then turn 45 degrees anticlockwise. Walk another 15 yards, reverse your directions and walk 5 yards back. Turn 135 degrees clockwise and walk another 10 yards. To determine in which direction you are now facing, the following logical reasoning must be carried out:

You start by walking 20 yards west, then turning 90 degrees clockwise, turning south. Then you walk 10 yards and turn counterclockwise 45 degrees, to the southwest. Later, you walk another 15 yards, turn the direction to the northeast, and walk 5 more yards. From the northeast turn 135 degrees clockwise to the west and walk 10 yards. Thus, the final sense in which the person is walking is to the West.

Thus the approach above is correct.

Answer:

Noah takes 20 minutes to get to his house, that is, 10 minutes less than Charlotte.

Step-by-step explanation:

Since Charlotte walks home from school every day at a rate of 4 miles per hour and it takes her 30-minutes to reach home, while her brother, Noah, runs home from the same school every day at a rate of 6 miles per hour, to determine how many fewer minutes does it take Noah than Charlotte to reach home from school each day the following calculation must be performed:

Charlotte:

4 mph = 4/60 = 0.0666 miles per minute

0.0666 x 30 = 2 miles

So the distance from the school to her house is 2 miles

Noah:

6/60 = 0.1 mile per minute

2 / 0.1 = 20

Thus, Noah takes 20 minutes to get to his house, that is, 10 minutes less than Charlotte.

Step-by-step explanation:

The function which represents the graph is : D. y = 3sin(x)

"A function is an expression which assigns each element of X to exactly one element of Y from a set X to a set Y."

"The graph of a function f is the set of all points in the plane of the form (x, f(x))."

"The graph of y=sin(x) is like a wave that oscillates between -1 and 1, in a shape that repeats itself every 2π units.

Also, the graph of sine function passes though origin, as sin(0) = 0 ."

"The graph of y=cos(x) is like the graph of y=sin(x) but shifted horizontally by π units"

From given graph, we can observe that the graph must be of sine function.

Also, given graph represents the graph of y = sin(x) expanded 3 times.

So, the function which represents the graph is, y = 3sin(x).

Hence, the correct answer is option D. y = 3sin(x)
