A cyclist travels at 10 km/hr for 2 hrs and then at 20 km/hr for 1 hr. Find the average speed.
Answer:
12.5 km/hr
Step-by-step explanation:
You find the mean after making them both the same measurement.
You would divide 10 by 2 to get 5 km/hr
You would use the 20 km/hr
You would add them and get 25
Then divide by 2 to find the mean and get 12. 5

Chose the equation of the line in slope-intercept form.
Answer:
Third answer choice
Step-by-step explanation:
Y intercept of the graph is -3 so you can eliminate the first two choices.
Then you see the slop is going up so its positive so you can eliminate the negative slope answer choice.
You are then left with the third answer choice and that is your answer.

Answer:
the second, fourth, fifth, and sixth
Answer:
2 - (-4)
4 + (-2)
5 - (-5)
6 - (-1)
Step-by-step explanation:
- 1 + (-5) = -1 - 5 = -6
2 - (-4) = 2 + 4 = 6
-3 + 2 = -1
4 + (-2) = 4 - 2 = 2
5 - (-5) = 5 + 5 = 10
6 - (-1) = 6 + 1 = 7

A triangular park has a walkway that is perpendicular to one of the sides of the park and divides that side into two equal parts, as
represented by the diagram.
121 m
2x+1
3x
What is the perimeter of the park?
The perimeter of this park based on the x value is equal to 422 m.
How to calculate the perimeter?Add all the sides of the triangle. This step implies finding the value of x, which is necessary to know the length of two of the three sides.
How to find out x?Assuming both perpendicular sides are equal, x can be expressed as:
2x + 1 = 1212x = 121 - 12x = 120x = 120/ 2x = 60This means, the lengths of the sides are:
121 m + 121 m + 180 m (3x) = 422 mLearn more about triangles in: https://brainly.com/question/16886469

1/5x + 1/2 = 3 + 1/2x
Answer:
X=-25/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/5x+1/2-1/2x=1/2x+3-1/2x
-3/10x+1/2=3
Step 3: Subtract 1/2 from both sides.
-3/10x+1/2-1/2=3-1/2
-3/10x=5/2
Step 4: Multiply both sides by 10/(-3).
(10/-3)*(-3/10)=(10/-3)*(5/2)
X=-25/3

Directions: Use each graph below to write the equation of the line in slope-intercept form y=mx + b. Make sure to show your work.
Answer:
Step-by-step explanation:
Y=mx+b
Slope (m) is rise over run.
1. rise= 4 run=5 therefore, slope=4/5
y=4/5x+b
b= y intercept
b= 4
Y=4/5x+4
2. rise= 1 run= 2 slope = -1/2
b= -1
Y= -1/2x - 1

Answer:
We need 8 and 3/4 cups of blueberries to make 7 batches of pancakes.
Step-by-step explanation:
A proportion is basically a statement that says two fractions are equal to each other. It's usually used to state the equivalence of two ratios, and is often in problems such as these, where you need to prove that the ratio of the original two objects are the same as the new two objects.
Let us set x to be the new amount of cups of blueberries.
Hence, we have to find the original ratio first. Let's say we want to use the ratio of cups of blueberries to batches to be the measuring stick (a quick tip would be to see what information is provided for the new ratio and use that information as the denominator). That ratio would be:
[tex]\frac{1 \frac{1}{4}}{1}[/tex]
[tex]= \frac{\frac{5}{4}}{1}[/tex]
[tex]= \frac{5}{4}[/tex]
So, now that we know the ratio of cups of blueberries to batches, we can use that information to construct a proportion:
[tex]\frac{5}{4} = \frac{x}{7}[/tex]
Great! Now it's just a matter of solving this equation:
[tex]\frac{5}{4} = \frac{x}{7}[/tex]
[tex]4x = 5 \cdot 7[/tex]
[tex]x = \frac{35}{4}[/tex]
[tex]x = 8 \frac{3}{4}[/tex]
Finally, we can know that we need 8 and 3/4 cups of blueberries to make 7 batches of pancakes.

Answer:
20 PERCENT
Step-by-step explanation:
BECUASE 40 INTO 60 AND THAT MEAN WE PLUS 20
Answer:
It would go up by 50%

then change that to 50% because the extra 1 is the 60 and then change the 0.5 to 50%
Prove that the triangle with vertices D(2,3), E(5,5), and F(4,0) is an isosceles triangle.
Answer: The bisector of angle F is a line segment from vertex F to the midpoint of line DE.
Midpoint: x = (2+6)/2 = 4; y = (-5+-1)/2 = -3
The midpoint is at (4,-3).
The equation of the line follows the point-slope formula:
y - y₁ = [(y₂ - y₁)/(x₂ - x₁)](x - x₁)
Substituting using points (5,6) and (4,-3)
y - 6 = [(⁻3 - 6)/(4 - 6)](x - 5)
y - 6 = (9/2)(x - 5)
2(y - 6) = 9(x - 5)
2y - 12 = 9x - 45
2y - 9x = -33

Solve the following
equation for X.
3x - 15 = -30
Answer:
X = -5
Step-by-step explanation:
3x - 15 = -30 You want to isolate tha variable
3x= -30+15 Add 15 to -15 in order to get rid of it. All you do to one side you do to the other, so you add 15 to 30
3x= -15
x= -15÷3 Divide x by 3 in order to get rid of the 3. Do it to the other side
x=-5
