Answer:

The kinetic energy of the car is 0.466 J

Correct Answer: A. 0.466 J Explanation: If there is no friction, all of the gravitational potential energy of the car at the top of the hill will be converted to kinetic energy at the bottom of the hill. The potential energy of the car is equal to the product of its mass, height, and gravitational acceleration.0.05 kg • 0.95 m • 9.81 m/s2 = 0.466 J.

Answer:

I'm going to say A

Step-by-step explanation:

For sure the next would be blue but this is just my guess.

The most likely next step in the series is Option A, where a blue ray is added 90 degrees to the left along with the existing rays.

It appears that the pattern involves adding a ray 90 degrees to the left and alternating colors between red and blue. The first figure is a 180 degrees line with arrows on both sides of red color.

Based on this pattern, the most likely next step would be to add a blue ray 90 degrees to the left, while keeping the existing rays and alternating colors. Therefore, the next step would be Option A, where the figure is blue in color with a ray added to the left along with the already present rays.

Answer:

Step-by-step explanation:

S = 2πr² + 2πrh

To solve for h move 2πr² to the other side of the equation

Answer/Step-by-step explanation:

Length of AC:

Given that AB = x + 2, and BC = 7x - 3, therefore,

[tex] (x + 2) + (7x - 3) = AC [/tex] (segment addition postulate)

Simply the expression for the length of segment AC

[tex] x + 2 + 7x - 3 = AC [/tex]

Collect like terms

[tex] x + 7x + 2 - 3 = AC [/tex]

[tex] 8x - 1 = AC [/tex]

Length of QR:

Given that PQ = 8y + 5, and PR = 13y + 25, therefore,

QR = (13y + 25) - (8y + 5) (PQ + QR = PR)

Simplify the expression to for the length of segment QR

QR = 13y + 25 - 8y - 5

Collect like terms

QR = 13y - 8y + 25 - 5

QR = 5y + 20

Answer:

12 (D)

Step-by-step explanation:

The first one is 2:1.2 so i did x10 on it to get 20:12.

The missing value in the table is 12 miles.

Option D is the correct answer.

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 hour = 60 minutes

1 km = 1000 m

1 minute = 60 seconds

We have,

Kilometer    Miles

2                     1.2

7                     4.2

20                  12

30                  18

We see that,

2 km = 1.2 miles

Multiply 7/2 on both sides.

7  km = 7/2 x 1.2 miles

7 km = 4.2 miles

Multiply 20/ 7 on both sides.

20 km = 12 miles

Thus,

20 km is 12 miles.

Answer:

They will meet in 1.8 hours.

Step-by-step explanation:

Given that, distance between trains = 306 miles

Let they take time [tex]'t'[/tex] to meet each other.

Speed of first train = 90 mph

Speed of second train = 80 mph

Let distance traveled by first train = [tex]D_1[/tex] miles

Formula for distance:

[tex]Distance = Speed \times Time[/tex]

Distance traveled by first train, [tex]D_1 = 90t[/tex]

Let distance traveled by first train = [tex]D_2[/tex] miles

Formula for distance:

[tex]Distance = Speed \times Time[/tex]

Distance traveled by first train, [tex]D_2 = 80t[/tex]

Total distance traveled is 306 miles.

i.e.

[tex]D_1+D_2=306\\\Rightarrow 90t +80t=306\\\Rightarrow 170t=306\\\Rightarrow t =\dfrac{306}{170}\\\Rightarrow \bold{t=1.8\ hr}[/tex]

Answer: Ray has 17 trucks .

Step-by-step explanation:

Let x = number of cars

y = number of trucks

As per given

x+y= 43    (i)

2y-8=x    (ii)

We can rewrite (ii) as

x-2y= -8      (iii)

Subtracting (iii) from  (i), we get

y- (-2y)= 43- (-8)

⇒ y+2y= 43+8

⇒ 3y=51

Divide both sides by 3

⇒ y = 17

Now, put this in (ii), we get

x= 2(17)-8=34-8 =26

Hence, Ray has 17 trucks and 26 cars.

Answer:

13

Step-by-step explanation:

9 more than a number y is

y + 9

If the number y is 4, then you have

4 + 9 = 13

The expression is y +9 and the evaluation is 13.

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Let y be the required number.

According to question,

the algebraic expression

y + 9

Here, y =4

Then y + 9

= 4 +9

= 13

Therefore, the expression is y +9 and the evaluation is 13.

Answer:

  any value other than 8

Step-by-step explanation:

If c = 8, the two sides of the equation say the same thing, so any value of x will satisfy the equation.

If c ≠ 8, there are no values of x that can make the equation true, hence no solutions.

There is no solution for any value of c that is not 8.

[tex]c=-3x+8+3x\\c=8[/tex]

If c = 8 then the solution is infinite. (because the equation is true)

[tex]-3x+7=-3x+8\\-3x+7+3x-8=0\\1=0[/tex]

If c < 8 then there're no solutions. (the equation is false)

[tex]-3x+9=-3x+8\\-3x+9+3x-8=0\\1=0[/tex]

If c > 8 then there're no solutions.

easy way. also if you look at the graph. It's literally impossible to have one intercept if the coefficient of x for both have the same operators and same absolute value like -2x+c = -2x + a or -3x+2 = -3x+5, we'll never get a single intercept. If we change like -3x+c = -5x+8, we might still get one solution.

I think C 130 probably wrong

Answer:

130 degrees

Step-by-step explanation:

Since there are vertical angles 2x and 3x-50 are the same. So you would do 2x=3x-50. The picture below shows how I got x=50. SO now you know x=50, it's important to remember that line AC equals 180 degrees. So what you nees to do is 180-50 to get what y equals. y should equal 130 degrees.

x < 0  , y > 0

Answer:

x < 0 and y > 0

Step-by-step explanation:

Quadrant II is the upper left quadrant.

In that quadrant, all x values are negative since it's to the left of the y-axis.

In that quadrant, all y values are positive since it's above the x-axis.

Answer: x < 0 and y > 0

Answer:

Solution : 3.6 miles

Step-by-step explanation:

The first step in solving this problem is to convert 15' to degrees --- (1) . 15' is represented as 15 minutes, so to convert to degrees we have 15 / 60 = 0.25°. Adding 20 + 15' we should get 20 + 0.25 = 20.25 (degrees).

Now remember that on the right side we have the football field, 62° 30'. Let's convert that 30' into degrees --- (2). 30 / 60 = 0.5, and 62 + 0.5 = 62.5.

Using both this information we can calculate the angle from the balloon to the horizontal. That would be 180 - 20.25 - 62.5 = 97.25°. Therefore the distance from the balloon to the soccer fields would be as follows,

distance / sin(62.5) = 4 / sin(97.25)

Let distance = x ...

x / sin(62.5) = 4 / sin(97.25),

x / 0.88701083317 = 4 / 0.99200494968,

x * 0.99200494968 = 4 * 0.88701083317,

x * 0.99200494968 = 3.548,

x = ( About ) 3.5766 miles

Given the options the distance from the balloon to the soccer fields would be 3.6 miles.
