HURRY!
The three vehicles shown below are driving down the street at a constant velocity of 5 m/s. The blue car has a mass of 700 kg. The red car has a mass of 1800 kg. The silver pickup truck has a mass of 3500 kg. Annie-Drew wants to make a line graph showing the relationship between the kinetic energy and mass of the cars traveling at a constant velocity. What would the graph look like?
Answers
Answer:
Step-by-step explanation:
As the change in speed of both cars is zero therefore tangential acceleration of both cars will be zero .
now centripetal acceleration is given by
a=v2/r
where, r= radius and v= linear velocity ,
for blue car ab=302/r
for grey van ag =152/r
radius is same for both as they round the same turn ,
So, ab /ag = 30 2/15
2 =4 or a
b =4a/g

Answer:
198
Step-by-step explanation:
length =11
width=18
Length times width = area
11 times 18 equals 198
i hope this helps! <3
168 cm
Explanation:
First we should find the area of the non-shaded parts
Length: 5cm
Width: 4cm
5x4=20
1st square= 20 cm
Length: 5cm
Width: 2cm
5x2= 10
2nd square= 10 cm
Now we add:
20+10=30
Shaded part:
11x18=198
We have to subtract the shaded part by the non shaded part:
198-30=168
Answer= 168cm
Page 2:
Answer 1:
Both are equal
Explanation:
Both are equal because:
A: 8+8+2+2
16+4=20
A=20cm
B: 5+5+5+5
5x4=20
B=20 cm
Answer 2:
16
Explanation:
Since we are already given the product we need to find the factors, square has 4 equal sides so we have to divide by 4:
64/4=16
Ans=16cm
Answer 3:
62cm
Explanation:
We need to divide the shape into 2.
Rectangle 1:
10+5+?+?
Since we already know what one side is it will be the same on the other side:
10+10+5+5
20+10=30
Rectangle 1=30cm
Rectangle 2:
Here we start to add and subtract:
Length: 10-5=5
Width: 6+5=11
5+5+11+11
10+22=32
32 cm
Total:
Now that we know both perimeters we add:
32+30=62
Total=62cm

Doira has a company that sells plants. She sells 34 for plants for $9,000 each her first day. The next couple days she sells 34 for $99,999 each. If she keeps selling them for $99,999 each for 100 weeks,how many plants will she have sold? How much money will she have made?
Answers
Answer:
1)23,800 plants.
2)$2,380,068,200
Step-by-step explanation:
1) if Doira sells 34 plants for $99,999 each for 100 weeks, she will have sold a total of 23,800 plants.
2.On the first day, Doira sold 34 plants for $9,000 each, so she made a total of 34 x $9,000 = $306,000.
In the following days, she sold 34 plants for $99,999 each, so her daily earnings were 34 x $99,999 = $3,399,966.
If she continues to sell 34 plants for $99,999 each for 100 weeks, she will sell a total of 34 x 100 x 7 = 23,800 plants.
Her total earnings from selling 34 plants for $99,999 each for 100 weeks will be 23,800 x $99,999 = $2,379,762,200.
Adding her earnings from the first day, her total earnings will be $2,379,762,200 + $306,000 = $2,380,068,200.
Answer: she would sell 340 plants and make $9,999,900
Step-by-step explanation:
34 x 100 =340
99, 999 x 100 = 9,999,900

Find the perimeter and area.
a. Rectangle, L=14m and B=9.5m
b. Square, side=14.5cm
c. Rectangle, L=25cm and B=16.8cm
Grade#8
Answers
Therefore, the perimeter and area of the given shapes are:
a. Perimeter = 47m, Area = 133m²
b. Perimeter = 58cm, Area = 210.25cm²
c. Perimeter = 83.6cm, Area = 420cm²
Step by step solved:
a. To find the perimeter of a rectangle with length L=14m and breadth B=9.5m, we use the formula:
Perimeter = 2(L+B)
Plugging in the values, we get:
Perimeter = 2(14m + 9.5m) = 2(23.5m) = 47m
To find the area of the rectangle, we use the formula:
Area = L x B
Plugging in the values, we get:
Area = 14m x 9.5m = 133m²
b. To find the perimeter of a square with side length=14.5cm, we use the formula:
Perimeter = 4 x side
Plugging in the value, we get:
Perimeter = 4 x 14.5cm = 58cm
To find the area of the square, we use the formula:
Area = side²
Plugging in the value, we get:
Area = 14.5cm x 14.5cm = 210.25cm²
c. To find the perimeter of a rectangle with length L=25cm and breadth B=16.8cm, we use the formula:
Perimeter = 2(L+B)
Plugging in the values, we get:
Perimeter = 2(25cm + 16.8cm) = 2(41.8cm) = 83.6cm
To find the area of the rectangle, we use the formula:
Area = L x B
Plugging in the values, we get:
Area = 25cm x 16.8cm = 420cm²
Answer:
Step-by-step explanation:
rectangle Perimeter = 2(l+b)
So, 2(14+9.5)
=> 46.5m
area = lb
So, 14*9.5
=> 133m^2
Square Perimeter = 14.5*4
= 58cm
Area = 14.5^2
= 210.25m^2
Rectangle #2
2(25+16.8)
=> 83.6 cm
Area = 420m^2

Answers
From my understanding and your lack of a picture:
The triangle CAT has rotated in 90 degrees clockwise direction about the origin or 270 degrees counterclockwise direction about the origin.
Step-by-step explanation:
From the given figure it is noticed that the coordinates of the vertices of the pre-image are C(-2,1), A(-3,3) and T(1,1). The coordinates of the vertices of the image are C'(1,2), A'(3,3) and T(1,-1).
From these coordinates, we can conclude that the relation between the preimage and image is
If a figure rotated 90 degrees clockwise direction about the origin, then
Therefore triangle CAT is rotated 90 degrees clockwise direction about the origin or 270 degrees counterclockwise direction about the origin.

Answers
Answer:
The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.
If (−6,4) satisfies the equations of two lines, (−6,4) is a point on both lines, so the lines will intersect at (−6,4).
This means that if two lines intersect at (−6,4), then (−6,4) is the solution to the system of equations.
This means that if you substitute −6 for x and 4 for y in the equations, both equations will be true. However, this information alone is not enough to determine whether a system of linear equations has a solution just by looking at the graph of the equations

The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.

If (−6,4) satisfies the equations of two lines, (−6,4) is a point on both lines, so the lines will intersect at (−6,4).

Step-by-step explanation:
Log of wood = (8x+12)
piece length = (4x+3)
So, (8x+12) - (4x+3)

What is 5/6 of 14 1/2?
PLEASE explain how it is!
please help its last question and i been on it for 15 minutes
Answers
Answer:
5/6 of 14 1/2 is 12.08333333
Step-by-step explanation:
14 1/2 = 14.5
14 = 14
and 1/2 = 0.5
now, you take 14.5 and divide by the denominator of the fraction that you have, which is 6
14.5 ÷ 6 = 2.416666667
and now you take 2.416666667 and multiply that by 5, because you are trying to find 5/6 of this number
2.416666667 × 5 = 12.08333333
So your answer is 12.08333333
You basically just multiply 5/6 and 14 1/2 which is 145/12 and that simplified is 12 1/12

Based on the information in the equation, which statements are true?
A. The cooler is meant to be used by only 24 players.
B. Before practice, there are 648 ounces of sports drink in the cooler.
C. If 24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink.
Answers
Answer:
Step-by-step explanation:
ounces of sports drink in the cooler.
C. Each player is expected to drink 24 ounces of sports drink during practice.
D. If no players take drinks from the cooler, there will be 648 ounces of sports drink in the cooler after practice.
Statement B is true: Before practice, there are 648 ounces of sports drink in the cooler, as the y-intercept of the equation is 648.
Statement C is not true: The coefficient of x, -24, does not represent the amount of sports drink each player is expected to drink. It represents the rate at which the amount of sports drink in the cooler decreases as players take drinks.
Statement D is not true: If no players take drinks from the cooler, x would be 0, and the amount of sports drink in the cooler after practice would be y = -24(0) + 648 = 648. However, this situation is not realistic, as players would normally take drinks from the cooler during practice.
Statement A is not true: The equation does not limit the number of players who can use the cooler. The equation only models the rate at which the amount of sports drink in the cooler decreases as players take drinks.
In mx+b, b is initial value meaning they started with 648 ounces

Factorize The Equation,
[tex] \frac{2x + 12}{(x + 6)(x - 6)} \\ = \frac{2(x + 6)}{(x + 6)(x - 6)} \\ = \frac{2}{x - 6} [/tex]
From the Given function,
x-6 ≠ 0
x ≠ 6
Thus x ≠ 6 is a restriction.
The solution is : x ≠ 6, is a restriction on the variables

=(2x+12)/(x-6) (x+6)
Factorize The Equation,
(2x+12)/(x-6) (x+6)
= 2(x+6) /(x-6) (x+6)
=2/ (x-6)
From the Given function,
x-6 ≠ 0
