b is wrong it is c
hope it helped
Step-by-step explanation:
The distance is less than one kilometer, because one kilometer is equal to 100000 centimeters.
What is kilometer?A kilometer is a unit of the metric system that is used to measure length or distance. It is mainly used to express a distance as a unit of the International System of Units (SI units).
1 kilometer = 1000 meters.
1 meter = 100 centimeters
1 kilometer = 100000 centimeters
Hence, the distance is less than one kilometer.

Which graph represents y= 2/3x+3? Please explain
Answers
Answer:
The graph in the image is the correct one
Step-by-step explanation:
The slope intercept equation is y=mx+b, "m" is the slope and the "b" is the y-intercept
the y-intercept is the point where the lines crosses the y-axis and on the graph that point is 3, so our "b" would be 3, y=mx+3
Now, an easy way to get our slope is rise over run (rise/run) Start from any point where the line touches a point and count striaght up until you find another point and go to the left/right depending on where the point is. if we do that, we will get 2/3 as our slope/"m", y=2/3x+3
We can also find the slope using the slope formula, [tex]m=\frac{y2-y1}{x2-x1}[/tex]
just find 2 coordinates on the graph and plug them in. If you have a graph, then I would recommend rise over run (rise/run)
feel free to ask any questions or comments
The coordinates points to plot on graph are (0, 3), (3, 5), (6, 7) and (9, 9).
What is the graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.
The given equation is y= 2/3x+3.
Graph the line using the slope and y-intercept, or two points.
Slope: 2/3
y-intercept: (0, 3)
Put x=0, 1, 2, 3, 4,....
When x=0
y= 2/3x+3=3
When x=3
y=5
When x=6
y=7
When x=9
y=9
So, the coordinates are (0, 3), (3, 5), (6, 7) and (9, 9)
Therefore, option C is the correct answer.

A biker’s speed is 1.5 times faster than a walker’s speed. They start moving simultaneously in the same direction from the same point and, after 1.5 hours, the distance between them is 12.5 miles. What are their speeds?
Answers
Answer: Speed of walker and biker will be 16.67 miles per hour and 25 miles per hour respectively.
Step-by-Step explanation:
Leave the speed of a walker alone x
Let the speed of a biker be 1.5x
They are moving a similar way,
thus, their Relative speed will be
1.5x - x =0.5x
Time taken = 1.5 hours
Separation between them = 12.5 miles
As we probably am aware the equation for "Distance":
*Picture attached*
Consequently, the Speed of the walker be 16.67 miles every hour
Speed of biker be
1.5 times 16.67=25 miles per houe
The speed of the walker and the biker will be 16.67 miles per hour and 25 miles per hour.
What is speed?Speed is the distance that a particle or body travels in one hour. It has a scalar value. It is the time-to-distance ratio.
We know that the speed formula
Speed = Distance/Time
A biker’s speed is 1.5 times faster than a walker’s speed.
Let y be the speed of the biker and x be the speed of the walker. Then the equation is given as,
y = 1.5x
They begin going simultaneously from the same location in the same direction, and after 1.5 hours, there are 12.5 miles separating them.
y - x = 12.5 / 1.5
1.5x - x = 25/3
0.5x = 25/3
x = 16.67 miles per hour
Then the speed of the biker will be given as,
y = 1.5 (16.67)
y = 25 miles per hour
The speed of the walker and the biker will be 16.67 miles per hour and 25 miles per hour.

Anjali is putting a border around a right triangle and needs to figure out the triangle's height. If the triangle has a base length of 18 in. and a total area of 36 in.2, what is the height?
Answers
Answer:
4
Step-by-step explanation:
the formula for area of a triange is 1/2bh, so fill in the variables and set that equal to 36
Height of the right angled triangle is equals to 4in.
What is right angled triangle?" A right angled triangle is a two dimensional closed figure with three vertices and three angles, one of the angle should be of measure 90 degrees."
Formula used
Area of right angled triangle = ( 1 / 2) × base × height
According to the question,
Base of the right angled triangle = 18in.
Area of the right angled triangle = 36 in²
Let 'h' represents the height of the triangle
Substitute the value in the formula we have,
36 = ( 1 / 2) × 18 × h
⇒36 = 9h
⇒ h = 4in.
Hence, height of the right angled triangle is equals to 4in.

An elevator can hold less than 2700 pounds of extra weight. If an average person weighs 150 pounds, what is the maximum number of people (p) that can be on the elevator at one time?
(A) p ≤ 18
(B) p > 18
(C) p < 18
(D) p ≥ 18
Answers
Answer:
(A) p ≤ 18
Step-by-step explanation:
p = people obviously
If you divide 2700 and 150 you get 18
2700/150 = 18
So now this is where you have to think a little, if 18 people get on an elevator then they are at maximum weight capacity. But if 17 people or less get on then they don't exceed the weight limit for therefore p can be less than or equal to 18, which is why this sign (≤) is there, the little line under the less then sign means it can be less than or equal to.

whats the answer to 29-(2c+3)=2(c+3)+c
Answers
Answer:
29-(2c+3)=2(c+3)+c=
We move all terms to the left:
29-(2c+3)-(2(c+3)+c)=0
We get rid of parentheses
-2c-(2(c+3)+c)-3+29=0
Step-by-step explanation:
Answer:
Solution for 29-(2c+3)=2(c+3)+c equation:
Simplifying
29 + -1(2c + 3) = 2(c + 3) + c
Reorder the terms:
29 + -1(3 + 2c) = 2(c + 3) + c
29 + (3 * -1 + 2c * -1) = 2(c + 3) + c
29 + (-3 + -2c) = 2(c + 3) + c
Combine like terms: 29 + -3 = 26
26 + -2c = 2(c + 3) + c
Reorder the terms:
26 + -2c = 2(3 + c) + c
26 + -2c = (3 * 2 + c * 2) + c
26 + -2c = (6 + 2c) + c
Combine like terms: 2c + c = 3c
26 + -2c = 6 + 3c
Solving
26 + -2c = 6 + 3c
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-3c' to each side of the equation.
26 + -2c + -3c = 6 + 3c + -3c
Combine like terms: -2c + -3c = -5c
26 + -5c = 6 + 3c + -3c
Combine like terms: 3c + -3c = 0
26 + -5c = 6 + 0
26 + -5c = 6
Add '-26' to each side of the equation.
26 + -26 + -5c = 6 + -26
Combine like terms: 26 + -26 = 0
0 + -5c = 6 + -26
-5c = 6 + -26
Combine like terms: 6 + -26 = -20
-5c = -20
Divide each side by '-5'.
c = 4
Simplifying
c = 4

For two figures to be considered congruent, their corresponding sides and angles must all be the same. Congruence can occur in any geometric figures, from simple line segments to complicated shapes with many sides and angles. Here’s another way to think about congruence: if you cut two figures out of paper, you could place one cutout on top of the other cutout and it would disappear. Consider that geometric figures are made up of an infinite number of points. When superimposed on top of each other, all of the points in one figure would match up with all of the points in the other figure.
According to the passage, which of the following is not true?
A
Paper cutouts can be used to determine congruence.
B
Congruent figures have exactly the same size and shape.
C
Congruence only happens in three- or four-sided figures.
D
Two octagons can be congruent if their corresponding sides and angles match up.

Frank finds 9 coins on the floor of his car, and 3 of them are quarters. If he finds 15 more coins on the ground, at the same ratio as the coins found in the car, how many more coins will most likely be quarters?
Answers
3 is 1/3 of 9, meaning the probability of picking up a quarter is 1/3, if he finds 15 more,
15/3 is 5.
5 coins should be quarters
Answer: 5 coins
Step-by-step explanation:
Frank found 9 coins on the floor of his car, and 3 of them were quarters. This means that 3 out of the 9 coins, or [tex]\frac{3}{9}[/tex], were quarters.
Simplifying this fraction, we get [tex]\frac{1}{3}[/tex] of the coins found in the car were quarters.
If Frank finds 15 more coins on the ground at the same ratio, then [tex]\bold{\frac{1}{3}}[/tex] of these coins will also be quarters. To find out how many quarters he will most likely find, we need to find [tex]\bold{\frac{1}{3}}[/tex] of 15:
[tex]\large \frac{1}{3} \times 15 = 5[/tex]
Therefore, Frank will most likely find 5 more quarters on the ground, assuming he finds coins at the same ratio as he did in his car.
