Question:
2 people A and B travel from X to Y along different routes. Their journeys take the same amount of time. B's route is 100km at an average speed of 40km/hour A's route is 60km. What is A's average speed?
Answer:
Person A's average speed is 24km/hr
Step-by-step explanation:
Given
Person B
[tex]Distance = 100km[/tex]
[tex]Speed = 40km/hr[/tex]
Person A
[tex]Distance = 60km[/tex]
Required
Average speed of person A
Speed is calculated as:
[tex]Speed = \frac{Distance}{Time}[/tex]
For person B
[tex]40 = \frac{100}{Time}[/tex]
Make Time the subject
[tex]Time= \frac{100}{40}[/tex]
[tex]Time= 2.5hr[/tex]
For person A
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Speed = \frac{60}{Time}[/tex]
The journeys last for the same duration.
So;
[tex]Speed = \frac{60}{2.5}[/tex]
[tex]Speed = 24[/tex]
Person A's average speed is 24km/hr

Find the median of the data in the bar chart below 4 11 5 8
Answer:
The median is 6.5 :)
Step-by-step explanation:
Brainliest please?
The median of the data in the bar chart given is 6.5 kilometers.
What is Median?Median of a data set is the element in the middle if the data are arranged in increasing or decreasing order.
Given is a bar chart which shows the distance that each family member run in a relay race.
The data is given as :
4, 11, 5, 8
In order to find the median, first arrange the data in an increasing order.
4, 5, 8, 11
Since there are even number (4) of data points, median is the average of the middle two elements.
Median = (5 + 8) / 2 = 6.5 km
Hence the median of the given data is 6.5 kilometers.

Answer:
32.5 units²
Step-by-step explanation:
We can find the area by dividing the figure into two shapes. If we solve for the area of a square and a triangle, we can add them together.
First, we can solve for the area of the 5x5 square. To find the area, we can multiply the two dimensions.
5 · 5 = 25 units²
Next, we can find the area of the triangle. It has an equal height to the square, so the height of the triangle is 5 units. The width isn't specified. Instead, we are shown that the width of both the square and the triangle equals 8 units. If we subtract the width of the square from the total, we can find the width of the triangle, too.
8 - 5 = 3
So, the height and the width of the triangle are 5x3. To find the area we can multiply these together, and then divide the product by two.
5 · 3 = 15
[tex]\frac{15}{2}[/tex] = 7.5
The area of the triangle is 7.5 units².
Finally, we can add the area of the triangle and the square together.
25 + 7.5 = 32.5
The area of the figure, then, is 32.5 units².
The answer is the last option.

Sam and her brother Nate are collecting stamps together. Nate has collected 5 more than twice the number of stamps Sam has collected. In total they have 26 stamps. Let n be the number of stamps that Sam has collected. Which of the following equations models this situation?
1. 2n+5=26
2. n+2n+5=26
3. 2n+5-n=26
4. n+2(n+5)= 26
Answer:
2. n(2n+5)=26.
Step-by-step explanation:
If Sam has n stamps, and Nate has 5 more than twice that amount, the equation would be: 2. n(2n+5)=26.

Answer:
Ok first of all you start out splitting the shape into seperate rectangles, in this case 2. take those 2 rectangles and find the area of them. Say we start from the smaller rectangle. 2 x 4 = 8 so the area of the smaller rectangle is 8. Keep that in mind. Next we have to multiply 10 x 5 because that is the labeled number of meters and that equals 50. So add 50 + 8 = 58
Step-by-step explanation:
Your answer is 58 meters
Really hope i helped and have a wonderful day! :)
Answer:
58 m³
Step-by-step explanation:
To find the area of irregular shapes like this, it is easy to split the shape into 2 individual shapes, find the area of both, then add the areas to find the total.
Now, we'll split it into 2 rectangles with areas of:
2 x 4
10 x 5
To find area, you multiply the length of one side by the other. The first rectangle's area is (2 x 4) and the other rectangle's area is (10 x 5).
10 x 5 = 50
2 x 4 = 8
50 + 8 = 58
The area of the figure is 58 m³.
If 3 out of 4 people use a certain headache

112,800 use the headache medicine.
Answer:
option D
Step-by-step explanation:
Out of 4 , 3 use headache medicine . So the fraction is 3/4 .
Total number of people in city = 150,400 .
So ,
⇒ n = 3/4 × Population
⇒ n = 3/4 × 150,400

4h + 6 = 30
h =___?
Im in 7th grade and I really need help
Answer: h = 6
explanation:
first u get h by itself
4h + 6 = 30
subtract 6 from both sides
4h = 24
divide by 4 on both sides
h = 6
Answer:h=3/13
Step-by-step explanation: Subtract 6 from both sides of the equation 4h+6-6=30h-6 you simplify 4h=30h-6. Subtract 30h from both sides of the equation then you get -26h=-6 then you divide both sides of the equation by the same term -26h/-26=-6/-26 and your answer is 3/13.

3/10 inches apart
Step-by-step explanation:
total miles based on 2" equals 33 miles can be found by solving this proportion:
2/33 = 6/x
2x = 198
x = 99
99 miles divided by 11 rest stops means each stop is 9 miles apart
now use new ratio of 1" equals 30 miles
1/30 = x/9
30x = 9
x = 9/30 or 3/10 inches

The area of a circle is 4π in². What is the circumference, in inches? Express your answer in terms of π.
Answer:
C = 4π in
Step-by-step explanation:
We require to find the radius r of the circle
Given the area is 4π , then
πr² = 4π ( divide both sides by π )
r² = 4 ( take the square root of both sides )
r = [tex]\sqrt{4}[/tex] = 2
Then
C = 2πr = 2π × 2 = 4π inches
Answer:
4π in
Step-by-step explanation:
The formula for area is πr². We will work backwards from 4π. First, I will do √4 so I can find r.
√4 = 2
Now, I know that r = 2. Next, I will substitute r into the circumference formula which is 2πr.
2π(2) - I know r is 2 from my previous set.
Now, I will simplify.
2 · 2 π = 4π
Since the question is asking in terms of π, I will not simplify all the way, and leave pi as is.

At a high school soccer league, each team has m players. There are 20 teams in
the league. Write the expression of the total number of players at the league.
Answer:
20m
Step-by-step explanation:
Given:
Number of players per team = m
Number of teams in the league = 20
The number of players in the league is the product of the number of payers in each team and the number of teams in the league.
This the expression to obtain the total number of players goes thus :
Total number of players in the league = 20 * m
Total Numbr of players in the league = 20m
A box is filled with 9 yellow cards, 5 red cards, and 6 blue cards. A card is chosen at random from the box. What is the probability that it is a yellow or a blue card? Write your answer as a fraction in simplest form
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
9 + 5 + 6 = 20 (how many cards there are altogether)
9 yellow + 6 blue = 15 (how many cards are either yellow or blue)
so:
[tex]\frac{15}{20}[/tex]
simplified:
[tex]\frac{3}{4}[/tex]
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
There are 20 total cards ( 9 + 5 + 6). 15 of them are yellow or blue(9 + 6). So, the fraction is [tex]\frac{15}{20}[/tex]. [tex]\frac{15}{20}[/tex] simplifies to [tex]\frac{3}{4}[/tex].
