Luke's square mosaic increased in area by 3.25 square meters after he added a border, turning the side length from 3 meters to 3.5 meters.

Luke originally made a square mosaic with side lengths of three meters. The area of this original square is calculated by squaring the side length: 3 meters × 3 meters = 9 square meters. When Luke added a border to his mosaic, the side length became 3.5 meters. Calculating the new area, we square the new side length: 3.5 meters × 3.5 meters = 12.25 square meters.

The increase in the area of the mosaic is the difference between the new area and the original area, which is 12.25 square meters - 9 square meters = 3.25 square meters. Therefore, the area of Luke's mosaic has increased by 3.25 square meters after adding the border.

Answer:

If x=0, then f(0) = -15

If f(x) = 27, then x = 3

Step-by-step explanation:

Find where the x column on the table has a 0 and find the corresponding f(x) value which is -15.

Do then same for the other question but find where f(x) on the table is equal to 27 and find the corresponding x value which is 3

If x=0, then f(0) =  -15

If f(x) = 27, then x =  3

We are given a table of values as follows:

             x              f(x)

             -3              33

             -2              17  

              0              -15

              2               -7

              3               27

This means that x is the independent variable and f(x) is the dependent variable corresponding to the variable x.

Hence, from the table of values we have:

If x=0, then f(0) =  -15

If f(x) = 27, then x =  3

Answer:

If 10 minutes block, then it can be rented for 20 minutes. If no blocks, then 27.27 minutes

Step-by-step explanation:

Initial setup cost is $6.

Every 10 minutes, $5.5 is charges, so each minute  [tex]\frac{5.5}{10}=0.55[/tex] is charged.

Let time used be t, so we can set up an equation as:

21 = 6 + 0.55t

Where t is in minutes

we solve for t to find out how many minutes we can rent for $21:

[tex]21 = 6 + 0.55t\\21-6=0.55t\\15=0.55t\\t=\frac{15}{0.55}=27.27[/tex]

since it is charged PER 10 MINUTES, so we can rent it for 10, 20 , 30 minutes etc.

WE CANNOT RENT FOR 30 minutes as we dont have enough money (only for fractional amount of a little over 27 minutes). Thus, we will have to have some money left over and rent for 20 minutes.

For $21, you can rent approximately 20 minutes of time at the local copy center when there's a $6 setup charge and each 10-minute period costs an additional $5.50.

The question is asking how much time can be rented for $21 at a local copy center, where there's a $6 setup charge and an additional $5.50 for every 10 minutes. To figure this out, we first need to subtract the setup charge from the total amount of money that can be spent. So, $21 - $6 = $15. Next, we need to see how many 10 minute increments can be rented with $15. Since each 10 minute increment costs $5.50, we divide $15 by $5.50 to get approximately 2.72. Since we can't rent time in fractions of a minute, we round this down to 2. Therefore, we can rent about 20 minutes of time for $21.

Answer:

450pi

Step-by-step explanation:

The volume of this figure is just the sum of the volumes of two cones. They both have radius of 5 and one has a height of 7 and the other has a height of 11.

The easiest way (for me) to calculate the volume is to find the average of the heights (9) and multiply the volume of a cone with the same radius as the other two and the other height by two.

The volume for a cone is just (pi*r^2*h)/3, so the 'average' cone's volume is 25pi * 9/3 or 75pi.

Double this to get 150pi.

Alternatively, you could calculate the volumes of the two cones using separate heights, but here you will end up with non-whole numbers (times pi) for both cones if you use that method.

Answer:

471.24 in³

Step-by-step explanation:

Volume of the left cone

= 1/3 π (5)²(7)

= 175π/3 in³

Volume of the right cone

= 1/3 π(5)²(11)

= 275π/3 in³

Total volume

= 175π/3 + 275π/3  

= 150π

= 471.24 in³

To find the actual speed and direction of the canoe, we can add the velocity of the canoe relative to the water to the velocity of the current. Using vector addition, the approximate resultant velocity of the canoe is 2.19 miles per hour at an angle of 51.3° relative to the shore.

To find the approximate actual speed and direction of the canoe, we can use vector addition. The canoe's velocity relative to the water is 2 miles per hour in the direction of 55°. The velocity of the current is 1 mile per hour due east. We can add these two vectors to find the resultant vector, which represents the total velocity of the canoe relative to the shore.

Using the formula for vector addition, we can find the magnitude and direction of the resultant velocity. The magnitude can be found using the Pythagorean theorem: Vtotal = √(Vcanoe)2 + (Vcurrent)2. The direction can be found using the tangent function: θ = tan-1(y/x), where y is the vertical component of the resultant vector and x is the horizontal component.

In this case, the resultant velocity of the canoe will be approximately 2.19 miles per hour (rounded to two decimal places) and the canoe will move in a direction of 51.3° (rounded to one decimal place) relative to the shore.

Answer:

The maximum distance riders travel in one full ride is:

                        1296.192 feet

Step-by-step explanation:

It is given that the diameter(d) of carousel is: 32 feet.

This means that the distance travelled in one revolution is equal to the circumference(C) of the circle.

We know that the circumference of circle is given by:

[tex]C=\pi\times d\\\\\\C=3.14\times 32\\\\\\C=100.48\ feet[/tex]

Also, Time of one full ride is:  3 minutes.

Speed of one full ride is: 4.3 revolutions per minute.

This means that the number of revolutions made is calculated as:

Number of revolution=Speed×Time

Number of revolution=4.3×3=12.9 revolutions.

Hence, total distance traveled in one full ride is:

Number of revolution made×Distance covered in one revolution

=  12.9×100.48

= 1296.192 feet

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x + 2 ← is in slope- intercept form

with slope m = 5

• Parallel lines have equal slopes, hence

y = 5x + c ← is the partial equation of the parallel line

To find c substitute (- 6, - 1) into the partial equation

- 1 = - 30 + c ⇒ c = - 1 + 30 = 29

y = 5x + 29 → A

The equation of the circle is (x - 1)^2 + (y - 2)^2 = 17.

The equation of a circle can be written in the form:

(x - h)2 + (y - k)2 = r2

Where (h, k) is the center of the circle and r is the radius.

In this case, the center of the circle is (1, 2) and it passes through the point (0, 6).

So, the distance between the center and the point is equal to the radius of the circle.

Using the distance formula, we can find the radius:

r = sqrt((0 - 1)2 + (6 - 2)2) = sqrt(1 + 16) = sqrt(17)

Therefore, the equation of the circle is:

(x - 1)2 + (y - 2)2 = 17

Answer:

11.2 feet

Step-by-step explanation:

The width of the actual train car, to the nearest foot, is 11 feet.

To find the width of the actual train car, we need to use the scale factor provided.

Given:

- Width of the model train's car = 2.4 inches

- Scale = 1:56

To find the actual width, we'll use the scale factor:

[tex]\[ \text{Actual width} = \text{Model width} \times \text{Scale factor} \][/tex]

First, we need to convert the width of the model train's car from inches to feet because the scale factor is given as a ratio. There are 12 inches in a foot.

[tex]\[ \text{Model width} = \frac{2.4 \text{ inches}}{12 \text{ inches/foot}} = 0.2 \text{ feet} \][/tex]

Now, we can find the actual width:

[tex]\[ \text{Actual width} = 0.2 \text{ feet} \times 56 = 11.2 \text{ feet} \][/tex]

Answer:

Step-by-step explanation:

Given in the question that,

speed of Aja = 3 miles/h

speed of Pete  = 4 miles/h

we know that Aja is 2 miles away from Pete  

Both will have covered same distance at the time they will catch up.

suppose time = x

               distance covered = y

Formula to use

distance = speed x time

Equation 1

3x  = y - 2

3x + 2 = y

Equation 2

4x = y

Equate both equation

3x + 2 = 4x

2 = 4x -3x

2 = x

Answer:

Pete will catch up Aja after 2 hours

Step-by-step explanation:

We can represent thsi problem as as system of equations.

Let

x =  be the time in which both Aja and Pete starte biking, (in hours)

y = the number of miles traveled by each

Aja begins 2 miles ahead of Pete and bikes at an average speed of 3 miles per hour. This means

y_Aja =  3*x + 2

Pete bikes at an average speed of 4 miles per hour.

y_Pete =  4*x

Then, we can find the intersection point between the graphs, so we find the solution.

Please see attached picture below

Pete will catch up Aja after 2 hours
