A car travels 200 meters, then turns right and travels 80 meters and finally makes a U-turn and travels another 120 m. If this is all done in 200
seconds, what is the average speed ?
help pleaseeeee
Answer:
2 m/s
Step-by-step explanation:
Since speed is total distance over time, we first need to find the total distance the car traveled.
Total distance = 200 + 80 + 120 = 400 m
total time = 200 sec
speed = distance/time = 400/200 = 2 m/s

Point M is the midpoint of FG. Can the value of variable a be determined? Explain.
a
G(24,30+3)
M(3,5)
F[b+1 a+2)
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A. To determine the value of a, set up and solve a system of equations in two variables. The value of a is
B. To determine the value of a, set the x- and y-coordinates of G and Fequal to each other and solve for a The value of a is
C. To determine the value of a, divide each coordinate of M by 2. Then add each quotient to the x-and y-coordinates of M. The value of a is
D. Not enough information is given for the value of a to be determined.
Answer:
A. To determine the value of a, set up and solve a system of equations in two variables. The value of a is 2
Step-by-step explanation:
Given the coordinates F(b+1, a+2, M(3,5) and G(2a, 3b+3), if M is the midpoint of F and G then, to get the value of a and b we will use the formula for calculating the midpoint a shown;
M(X, Y) = (x₁+x₂/2, y₁+y₂/2)
X = x₁+x₂/2 and Y = y₁+y₂/2
From the given coordinates x₁ = b+1, y₁ = a+2, x₂ = 2a, y₂ = 3b+3, X = 3 and Y = 5
Substituting the given parameters into the formula, we can form up a simultaneous equation and get the value of a.
To determine the value of a, set up and solve a system of equations in two variables
For the X coordinates;
X = x₁+x₂/2
3 = b+1+2a/2
6 = 2a+b+1
2a+b = 5 ............... 1 * 1
For the Y coordinates;
5 = a+2+3b+3/2
cross multiply
10 = a+2+3b+3
collect like terms
a+3b = 10-2-3
a+3b = 5 ........ 2 * 2
Solving the resulting simultaneous equation to get the value of a
multiply equation 1 by 1 and 2 by 2 to have the resulting equations;
2a+b = 5 ...........3
2a +6b = 10.......... 4
subtract 3 from 4
(2a-2a)+(b - 6b) = 5-10
0-5b = -5
b = -5/-5
b = 1
substitute b =1 into equation 1 to get a;
2a + b = 5
2a + 1 = 5
2a = 5-1
2a = 4
a = 2
From the calculation above it is seen that the value of variable a can be determined and it is equivalent to 2
A farmer has some chickens and rabbits. There are 60 eyes and 100 legs altogether. How many chickens and how many rabbits are there?
Answer:
20 rabbits, 10 chickens
Step-by-step explanation:
Because chickens and rabbits each have 2 eyes, the number of animals is 60 ÷ 2 = 30.
Let's say that all of the 30 animals are chickens. There would be a total of 30 × 2 = 60 legs.
So the extra (100 – 60) = 40 legs must have come from the rabbits.
Every rabbit has (4 – 2) = 2 more legs than a chicken.
So there are 40 ÷ 2 = 20 rabbits and 30 – 20 = 10 chickens.
Answer:
20 rabbits and 10 chicks

A new car is available with standard or automatic transmission, two or four doors, and it is available in 10 exterior colors. What is the number of possible outcomes? a.14 b.40 c.44 d.104
Answer:
40
Step-by-step explanation:
Given that:
Number of options available for transmission = 2 (Standard or Automatic)
Number of options for doors = 2 (2 doors or 4 doors)
Number of exterior colors available = 10
To find:
Total number of outcomes = ?
Solution:
First of all, let us calculate the number of outcomes for the transmission mode and number of doors options.
1. Standard - 2 doors
2. Standard - 4 doors
3. Automatic - 2 doors
4. Automatic - 4 doors
Number of outcomes possible = 4 (which is equal to number of transmission mode available multiplied by number of doors options i.e. 2[tex]\times 2[/tex])
Now, these 4 will be mapped with 10 different exterior colors.
Therefore total number of outcomes possible :
Number of transmission modes [tex]\times[/tex] Number of doors options [tex]\times[/tex] Number of exterior colors
2 [tex]\times[/tex] 2 [tex]\times[/tex] 10 = 40
The number of possible outcomes of a new car will be 40. Then the correct option is B.
What is a sample?A sample is a collection of well-defined elements. A sample is represented by a capital letter symbol and the number of elements in the finite sample is shown as a curly bracket {..}.
A new car is available with standard or automatic transmission, two or four doors, and it is available in 10 exterior colors.

I still don't get how to do this: Solve for t then simplify your answer. -6/5t=9
Answer:
t= -15/2 or t= -7.5
Step-by-step explanation:
We are given the equation:
[tex]\frac{-6}{5}t=9[/tex]
and asked to solve for t. Therefore, we must isolate t on one side of the equation.
t is being multiplied by -6/5. The inverse of multiplication is division. We should divided both sides by -6/5, but we are dividing by a fraction. Instead, we can multiply by the reciprocal.
To find the reciprocal, flip the numerator (top number) and denominator (bottom number).
-6/5 ----> -5/6
Multiply both sides of the equation by -5/6
[tex]\frac{-5}{6} *\frac{-6}{5}t=9 *\frac{-5}{6}[/tex]
[tex]t=9 *\frac{-5}{6}[/tex]
[tex]t=\frac{9}1 *\frac{-5}{6}[/tex]
Multiply across the numerator and denominator.
[tex]t= \frac{9*-5}{1*6}[/tex]
[tex]t=\frac{-45}{6}[/tex]
Simplify the fraction. Both the numerator and denominator can be divided by 3.
[tex]t=\frac{-45/3}{6/3}[/tex]
[tex]t=\frac{-15}{2}[/tex]
[tex]t= -7.5[/tex]
t is equal to -15/2 or -7.5

Answer:
25π/6 yd
Step-by-step explanation:
∠DCE = 110°, so arc DFE = 360° − 110° = 250°.
In radians, that's 250° × π/180° = 25π/18.
Arc length is:
s = rθ
s = (3 yd) (25π/18)
s = 25π/6 yd

Answer:
The line that can be drawn through points D and E is contained in plane Y.
Step-by-step explanation:
Let's just go through all of these answer choices.
The first one says that "The line that can be drawn through points C and D is contained in plane Y." Is this true? If we drew a line connecting points C and D, it looks like it would cross through both planes X and Y, so it cannot be contained in only plane Y. This is false.
The second one says that "The line that can be drawn through points D and E is contained in plane Y." If we imagine a straight line going from point D to point E, it looks like it's just a line in plane Y; so this can be contained in plane Y. This seems true.
The third one says that "The only point that can lie in plane X is point F." This is false because plane X has a ton of points, but point F is just the only one that's labeled. This is false
The fourth one is similar, and says that "The only points that can lie in plane Y are points D and E." Again, this is false because points D and E just happen to be the only two labeled points, but there are infinitely many points on plane Y; points D and E are not all of them.
The second answer choice is true.

Jim was offered a job as a computer programmer making 65K per year. Another company offered Jim a position earning $1,800 a week. What job pays more?
Answer:
since second company salary, $93,600, is more than first company yearly salary of $65000
Second company pays more
Step-by-step explanation:
To check what job pays more we have to compare yearly salary of both the company offer.
_________________________________________________
Yearly salary from one company = 65k = 65000
Weekly salary from another company = $1800
there are 52 weeks in a year
to get yearly salary , we need to multiply weekly salary with 52.
Yearly salary from another company = Weekly salary*no of wees in a year
Yearly salary from another company = 52*$1800 = $93,600
since second company salary, $93,600, is more than first company yearly salary of $65000
Second company pays more

The medicinal thermometer commonly used in homes can be read to pm0.1°F, whereas those in the doctor's office may be accurate to pm0.1°C. In degrees Celsius, express the percent error expected from each of these thermometers in measuring a person's body temperature of 38.7°C.
Correct question is;
The medical thermometer commonly used in homes can be read +/-0.1 °F, whereas those in the doctor's office may be accurate to +/- 0.1 C in degrees Celsius, express the percent error expected from each of these thermometers in measuring a person's body temperature of 38.9 °C
Answer:
A) percent error in homes = 0.144 %
B) percent error in doctors office = 0.257 %
Step-by-step explanation:
A) Temperature is 38.9° C
Converting to Fahrenheit using the formula; (°C × 9/5) + 32
So;
(38.9°C × 9/5) + 32 = 102.02 °F
Since thermometer in homes can be read to +/-0.1 °F, then
Expected values = 102.02 +/- 0.1 = 102.12 °F or 101.92 °F
Since we want to find the error from °C, let's convert to °C.
We will use 101.92 °F.
Thus; 102.12 °F = (101.92 - 32) × 5/9 = 38.844 °C
Thus percent error = (38.9 - 38.844)/38.9) × 100% = 0.144 %
B) Temperature is 38.9 °C
Since thermometer in Doctors office can be +/- 0.1 °C, then;
Expected values = 38.9 +/- 0.1 = 38.8 °C or 39 °C.
We will use 38.8°C
Thus;
percent error = (38.9 - 38.8)/38.9) × 100% = 0.257 %

What is the equation for a straight line?A straight line can be written in the form of equation as, y = mx + c.
Two straight lines intersect each other only at one point.
When two straight lines are parallel to each other the angle between them is zero.
The equation of the straight line from the given graph can be formed as below,
Take any two coordinates from the graph as (1, 10) and (2, 25) respectively.
Suppose the cost be y and the number of pajamas be x.
Now, the equation for the slope can be written as,
(y - 10)/(x - 1) = (25 - 10)/(2 - 1)
⇒ (y - 10)/(x - 1) = 15
⇒ y = 15x - 5.
Then, the cost of 6th pajama can be calculated by substituting x = 6 in the above equation as,
y = 15 × 6 - 5
= 85
Hence, the cost of sixth pair of pajama is $85.
