Jean climbed 2/3 of the distance to the top of the cliff as shown on the number line. Terry climbed 1/3 of the distance less than Jean. Steve climed 1/5 of the distance more than Jean. Drag the correct points to the correct locations on the number line.
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Jean = \frac{2}{3}[/tex]
[tex]Terry = \frac{1}{3}[/tex]
[tex]Steve = \frac{1}{5}[/tex]
Required
Represent them on number line
Start by getting the LCM of the denominators of the three fractions;
The denominator are: 3 and 5
[tex]LCM = 15[/tex]
This means that, the number line will be divided into 15 partitions;
Next, we get the position of each fraction as follows;
[tex]Jean = \frac{2}{3} * 15[/tex]
[tex]Jean = \frac{30}{3}[/tex]
[tex]Jean = 10[/tex]
Jean will be represented on the 10th point
[tex]Terry = \frac{1}{3} * 15[/tex]
[tex]Terry = \frac{15}{3}[/tex]
[tex]Terry = 5[/tex]
Terry will be represented on the 5th point
[tex]Steve = \frac{1}{5} * 15[/tex]
[tex]Steve = \frac{15}{5}[/tex]
[tex]Steve = 3[/tex]
Steve will be represented on the 3rd point
See Attachment for number line
Answer:
Jean climbed of the distance up the cliff. This is marked on the number line.
Terry climbed of the distance less than Jean. Use addition to find the height to where Terry climbed.
So, Terry climbed of the total distance.
Steve climbed of the total distance more than Jean. Use addition to find the point to where Steve climbed.
So, Steve climbed of the total distance.

Question 1
Which expression is equivalent to 16 + 36, rewritten as the product of the greatest common factor and the sum of the remaining numbers?
Question 2
An equation shown: 30 + 12 = _____(5 + 2). What factor is missing from the equation?
Question 3
What is the value of the expression 100.4 ÷ 0.25?
Answer:
Question 1
The equivalent expression of 16 + 36 is 4 × (4 + 9)
Question 2
The factor missing in the given equation is 6
Question 3
The value of the expression 100.4 ÷ 0.25 is 401.6
Step-by-step explanation:
Question 1
The given expression is 16 + 36
Which can be written in the greatest common factor form as 4 × 4 + 9 × 4
Therefore, the greatest common factor = 4
The expression 16 + 36, can therefore be written as 4 × 4 + 9 × 4 = 4 × (4 + 9)
The equivalent expression of 16 + 36 is 4 × (4 + 9)
Question 2
The given equation is 30 + 12 = ___(5 + 2)
Finding the greatest common factor of the terms 30 and 12, we get;
30 + 12 = 6 × 5 + 6 × 2
Therefore, by factorizing, we get;5
30 + 12 = 6 × 5 + 6 × 2 = 6 × (5 + 2)
30 + 12 = 6 × (5 + 2)
Comparing the above equation to the given equation, we get;
30 + 12 = 6 × (5 + 2)
30 + 12 = ___(5 + 2)
Therefore;
6 × (5 + 2) = ___× (5 + 2)
Therefore, the factor missing in the given equation is 6
Question 3
The given expression, 100.4 ÷ 0.25, can be expressed as follows;
(100 + 0.4)/0.25 = 100/0.25 + 0.4/0.25
Multiplying the expression by 100/100 gives;
100/100 × 100/0.25 + 100/100 × 0.4/0.25 = 10000/25 + 40/25
10000/25 + 40/25 = 400 + [tex]1\frac{15}{25}[/tex] = 400 + [tex]1\frac{3}{5}[/tex] = [tex]401\frac{3}{5}[/tex] = 401.6
100.4 ÷ 0.25 = 401.6
The value of the expression 100.4 ÷ 0.25 is 401.6.

Josie makes fruit punch by mixing fruit juice and lemonade in the ratio 3:4. She needs to make 49 liters of punch for the party. How much of each ingredient does she need
Answer:
juice = 21lemonade = 28Step-by-step explanation:
given:
ratio of juice and lemonade = 3:4
She needs to make 49 liters of punch for the party.
find:
How much of each ingredient does she need
solution:
add the ratio 3 + 4 = 7
total punch divide by the total ratio
49 / 7 = 7 (coefficient)
juice 3 x 7 = 21
lemonade 4 x 7 = 28
total = 49

The surface area of a cube is 1,350 m2. Find the volume of the cube.
Answer:
3375
Step-by-step explanation:
The surface area formula for a cube is:
A = 6 a^2
We know what the area is so plug it into the equation:
1350 = 6 a^2
225 = a^2
a = 15
Now plug a = 15 into the equation for volume of a cube:
V = a^3
V = 15^3
V = 3375
solve the following equation: x÷6-3=1
Answer:
x = 24
Step-by-step explanation:
1x / 6 - 3 = 1
+3 +3
1x / 6 = 4
x6 x6
1x = 24
/1 /1
x = 24
Answer:
x = 24
Step-by-step explanation:
Step 1: Write equation
x/6 - 3 = 1
Step 2: Solve for x
Add 3 to both sides: x/6 = 4
Multiply both sides by 6: x = 24
Step 3: Check
Plug in x to verify if it's a solution.
24/6 - 3 = 1
4 - 3 = 1
1 = 1
John took a 5 1/2 mile walk to his friend's house. He left at 11 a.M. And arrived at his friend's house at 12:45 p.M. Therefore it took him 1 3/4 hours to get to his friends house. If the return trip took 2 1/4 hours, what is the average speed on the return trip?
Answer:
The average speed on the return trip is 2.44 miles/h.
Step-by-step explanation:
To find the average speed we need to use the following equation:
[tex] \overline{v} = \frac{d}{t} [/tex]
Where:
d: is the distance
t: is the time
Since the question is to find the average speed on the return trip, we will take the data of the time and speed of only the return trip.
[tex]\overline{v} = \frac{d}{t} = \frac{5 + 1/2}{2 + 1/4} = 2.44 miles/h[/tex]
Therefore, the average speed on the return trip is 2.44 miles/h.

Which equation represents the linear function that is shown on the graph below?
On a coordinate plane, a line goes through points (4, 0), (6, 1), (8, 2), and (10, 3).
y = one-half x + 4
y = one-half x minus 2
y = 4 x minus 2
y = negative 2 x + 4
Answer:
It’s the second answer I just did it.
Step-by-step explanation:
The equation of line goes through points (4, 0) (6, 1), (8, 2), and (10, 3) is y = 1/2 x - 2
What is the Equation of line?The equation of the line with slope m and y-intercept at point b is given as;
y = MX + b
Given that On a coordinate plane, a line goes through points (4, 0), (6, 1), (8, 2), and (10, 3).
Now, Take two points and find the slope of the graph as,
Two points are (8, 2), and (10, 3)
Hence, Slope = (3 - 2) / (10- 8)
= 1/2
Thus, the Slope is 1/2.
The equation goes through points (4, 0) and is given as;
y - 0= 1/2(x - 4)
y = 1/2 x - 2
The equation of line goes through points (4, 0) (6, 1), (8, 2), and (10, 3) is y = 1/2 x - 2

Bonus Problem. Write equations of the following lines.
Line that is parallel to y=2x−4 and passes through the point (1,1).
Answer: y= 2x -1
Step-by-step explanation:
Parallel lines have the same slopes but different y-intercepts. In this case, we will just need to find the y-intercept for the line that is parallel to y=2x - 4.
To find the y intercept, we will need the point (1,1) by plotting in the x and y coordinate into the y intercept formula y=mx +b. m is the slope which will be 2 and b will be the y-intercept.
1 = 2(1) + b
1 = 2 + b
-2 -2
b = -1
The equation will be y= 2x -1
