Answer:

C. 19 cars; 19 motorcycles

Step-by-step explanation:

Let c represent the number of cars and m represent the number of motorcycles that participated this year.

This year a total of 38 vehicles participated. So, we can write the equation as:

c + m = 38                                                (Equation 1)

Each car has 4 tires, so number of tires in c cars will be 4c.

Each motorcycle has 2 tires, so number of tires in m motorcycles will be 2m.

In total there were 114 tires, so we can set up the equation as:

4c + 2m = 114                                          (Equation 2)

From equation 1, m = 38 - c. Using this value in Equation 2, we get:

4c + 2(38 - c) = 114

4c + 76 - 2c = 114

2c = 114 - 76

2c = 38

c = 19

Using this value in equation 1, we get:

19 + m = 38

m = 19

Thus, 19 cars and 19 motorcycles participated in the ride.

Answer:

[tex]13.19\ m[/tex]

Step-by-step explanation:

step 1

Divide the total height by the number of step leading

[tex]\frac{24}{91}=0.2637\frac{m}{step}[/tex]

step 2

Multiply [tex]0.2637\frac{m}{step}[/tex] by 50 step

[tex]0.2637(50)=13.19\ m[/tex]

If you were standing on the 50th step of the pyramid, you would be approximately 13.185 meters above the ground, calculated by finding the height per step and multiplying by the number of steps climbed.

The task is to calculate how high above the ground you would be if you were standing on the 50th step of a pyramid that has a temple approximately 24 meters above the ground with a total of 91 steps leading up to the temple. To solve this, we will assume that the height the steps cover (24 meters) is evenly distributed across the number of steps (91). So, each step represents 24 meters divided by 91 steps in height.

First, let's calculate the height of each step:

Height per step = Total height / Number of steps

Height per step = 24 meters / 91 steps ≈ 0.2637 meters per step

Next, we need to calculate the height at the 50th step:

Height at 50th step = Height per step * Number of steps climbed

Height at 50th step = 0.2637 meters per step * 50 steps ≈ 13.185 meters

Therefore, if you were standing on the 50th step, you would be approximately 13.185 meters above the ground.

8 more glasses

Step-by-step explanation:

12-4=8

Final answer:

After serving 4 glasses of the original 12 glasses of lemonade, Jasmine can serve 8 more glasses. We calculate this by subtracting the number of glasses already served from the total number of glasses the pitcher contains.

Explanation:

Jasmine made a pitcher of lemonade that contains 12 glasses. After she serves 4 glasses of lemonade, we can calculate how many more glasses, g, she can serve by subtracting the number of glasses served from the total number of glasses that the pitcher initially had. The equation then becomes: 12 glasses - 4 glasses = g.

To find the value of g, we subtract 4 from 12, which gives us:

g = 12 - 4 = 8

Therefore, Jasmine can serve 8 more glasses of lemonade from the pitcher.

Answer:

28 units

Step-by-step explanation:

The volume of the rectangular prism is 28 cubic units.

To find the volume of a rectangular prism, we use the formula:

Volume = Base Area * Height

The Base Area is 21/2 (21/2 = 10.5) and the Height is 8/3, we can calculate the volume as follows:

Volume = 10.5 * (8/3)

To multiply fractions, we simply multiply the numerators together and the denominators together:

Volume = (10.5 * 8) / 3

Volume = 84 / 3

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD), which is 3:

Volume = 28

So, the volume of the rectangular prism is 28 cubic units.

Final answer:

To calculate the radius of the cylindrical can, we use the volume of a cylinder formula, V = πr²h. After substituting the given values and solving for r, the radius of the can is found to be approximately 5.64 cm.

Explanation:

To find the radius of the cylindrical can that contains 1500 cm³ of coconut milk with a height of 15 cm, we can use the formula for the volume of a cylinder, V = πr²h, where V is the volume, r is the radius, and h is the height.

Given V = 1500 cm³ and h = 15 cm, we can rearrange the formula to solve for r (radius).

The rearranged formula is r = √(V/(πh))

Plug the values into the formula:

r = √(1500 cm³/(3.142 × 15 cm))

r = √(1500/47.13)

r = √(31.83)

r ≈ 5.64 cm

Therefore, the radius of the can is approximately 5.64 cm.

Answer:

rate of flow of hot water = 480 L/hour

and rate of flow of cold water = 720 L/hour

Step-by-step explanation:

Suppose rate of flow of hot water = x

and rate of flow of cold water = y

Given that,

Twice the water flow in the hot water pipe is equal to three times the water flow from the cold pipe.

Combined it equals 1200 L/hour.

According to the question

2x = 3y

x + y = 1200

x = 1200 - y

put this value of x in equation1

2(1200-y) = 3y

2400 - 2y = 3y

2400 = 5y

y = 480

x = 3(480)/2

x = 720

The flow rate in the hot water pipe is 720 L/hour, and the flow rate in the cold water pipe is 480 L/hour, solved through a system of linear equations.

The student's question involves solving a system of linear equations to find the flow rate in each pipe. The problem states that twice the flow in the hot water pipe is equal to three times the flow in the cold water pipe, and that combined, the flow is 1200 L/hour.

Let's define the flow in the hot water pipe as H liters per hour and the flow in the cold water pipe as C liters per hour. The two given conditions can be translated into the following equations:

To solve for H and C, we can use substitution or elimination method. First, we can solve Equation 1 for H to get:

H = 1.5C

Now, we substitute H in Equation 2 with 1.5C:

1.5C + C = 1200

Combining like terms, we get:

2.5C = 1200

Dividing both sides by 2.5, we find the flow rate of the cold pipe:

C = 1200 / 2.5

C = 480 L/hour

Now we can substitute C back into the equation for H to find the hot water flow:

H = 1.5 * 480

H = 720 L/hour

Therefore, the flow rate in the hot water pipe is 720 L/hour, and the flow rate in the cold pipe is 480 L/hour.

Scaling is the process in which the dimension of an object is multiplied or increased by the same ratio.  The actual area of the rectangular patio is 550 feet².

Scaling is the process in which the dimension of an object is multiplied or increased by the same ratio.

As it is given that the ratio by which the patio is scaled is 1 inch = 5 feet. Therefore, a single inch on the drawing is 5 feet in the real world.

Now, the dimensions of the patio on the scale drawing are 5.5 inches by inches, therefore, each of the dimensions will be scaled.

[tex]\text{Length of the Patio}= 5.5\rm \times 5 = 27.5\ feet[/tex]

[tex]\text{Width of the Patio} = 4 \times 5 = 20\rm\ feet[/tex]

Recall that you have to write complete question in order to get good and precise answers. I found a similar question and attached the options below. However, the question has missing graph, too. So let's face this problem in a general way.

1. It must be proportional because the points lie on the same line.

The points not not only must lie on the same line, but that line must pass through the origin because two quantities x and y are directly proportional if we can write an expression:

[tex]y=kx \\ \\ Being \ k \ the \ constant \ of \ proportionality[/tex]

That is, if x increases, y also increases at the same rate.

2. It must be proportional because each time x increases by 2, y stays the same.

In this case as x increases by 2, y stays the same, meaning that this relationship is constant. So in this case they aren't proportional, but we can write:

[tex]y=c \\ \\ Being \ a \ real \ constant[/tex]

3. It cannot be proportional because the y-values are not whole numbers:

This doesn't make sense. The only condition for a direct proportion is that the line must pass through the origin and for any constant of proportionality [tex]k[/tex]

4. It cannot be proportional because a straight line through the points does not go through the origin:

This is is true because the definition of direct proportion is that the line passes through the origin for some constant k:

Final answer is slope [tex]m=\frac{5}{2}[/tex]

Step-by-step explanation:

Given equation is [tex]5x-2y=7[/tex]

Now question says to find the slope.

Since given equation [tex]5x-2y=7[/tex] is a linear equation so we need to compare [tex]5x-2y=7[/tex] with slope intercept formula [tex]y=mx+b[/tex] to get the value of slope m.

Since [tex]5x-2y=7[/tex] is not in that form so first let's rewrite it in y=mx+b form

[tex]5x-2y=7[/tex]

[tex]-2y=-5x+7[/tex]

[tex]y=\frac{-5x+7}{-2}[/tex]

[tex]y=\frac{5}{2}x-\frac{7}{2}[/tex]

Now comparing with y=mx+b, we get [tex]m=\frac{5}{2}[/tex]

Hence final answer is slope [tex]m=\frac{5}{2}[/tex]

Answer:

Slope = 5/2

Step-by-step explanation:

It is given an equation of line  5x – 2y = 7

To find the slope of equation we have to rewrite this equation in y = mx + c form

To convert the given equation to y = mx + c

The given equation is

 5x – 2y = 7

⇒ 5x + 7 = 2y

⇒ 2y = 5x + 7

⇒ y = (5x + 7)/2

y = 5x/2 + 7/2

The above equation is of the form y = mx + c

Here slope = m = 5/2
