The polygons in each pair are similar. Find the scale factor of the smaller figure to the larger figure

Answer:

First part: 0.35 miles per minute

Second part: 3.5 miles in 10 minutes

Step-by-step explanation:

Think about this as a fraction. Fractions can't be added nor subtracted unless they share the same denominator. So for this case, we have to turn hours into minutes. So 21 mph becomes 21 miles per 60 minutes. Then, we divide 60 from each side to find the speed per minute. 21/60 = 0.35, so the answer to the first part is 0.35 miles per minute.

Using what we got, we can answer the second part of the distance covered in 10 minutes. So, we just multiply 0.35 by 10 which is 3.5 miles covered in 10 minutes.

Answer:

-$0.26

Step-by-step explanation:

Calculation to determine the expected value of playing the game once

Expected value= [18/(18+18+2) x $5)]- [20/(18+18+2) x $5]

Expected value= ($18/38 x $5) - (20/38 x $5)

Expected value= ($2.37-$2.63)

Expected value= -$0.26

Therefore the expected value of playing the game once is -$0.26

Answer:

40 minutes

Step-by-step explanation:

360/60 = 6 degrees per minute

240/6 = 40 minutes

Answer:

40 minutes / 2400 seconds

Step-by-step explanation:

One full rotation of a circle is 360°

One hour (full rotation of minute hand) is 60 minutes

360° = 60min

Divide both sides by 60

6° = 1min

So every 6° is 1 minute.

240° / 6° = (x minutes) / 1 minute

x = 40 minutes

Alternatively:

1 hour = 60 minutes

1 minute = 60 seconds

So, 1 hour = 60×60 = 3600 seconds

3600 seconds / 360° = 10 sec/°

==> This means that every 1° is 10 seconds on the minute hand

240° × 10 sec/° = 2400 sec

(Divide by 60 for 40 minutes)

Answer:

$ 645.85

Step-by-step explanation:

First you would plug 6,500 into P. The plug 2.5% as 0.025 into i. And plug the years (5) into n.

A = 6500 (1 + 0.025)^5 = 7354.15

That is the amount that would be in the account at the end of the 5 years.

Then you take the cost of the car (8,000) and subtract the money left in the account (7,354.15).

8000 - 7354.15 = 645.85

Your final answer would be rounded to the nearest cent, or the hundredths place.

Answer:

5:3

Step-by-step explanation:

40% = 2/5

If the numbers are x and y, then

2/5 x = 2/3 y

Divide both sides by 2/5

x  = (2/3 * 5/2)y

x = 10/6 y

x = 5/3  y

So the required ratio is 5 : 3.

Checking this result:

10% of 5 = 2

2/3 of 3 = 2 also.

5 times.

1a + 7b + 9a = 10a + 7b

2a + 7b + 8a = 10a + 7b

3a + 7b + 7a = 10a + 7b

4a + 7b + 6a = 10a + 7b

5a + 7b + 5a = 10a + 7b

Answer:

[tex]f(x)=\begin{cases}x^2 + 3; & \text{ } x<1 \\ -2\cdot x+5; & \text{ } x\geq 1 \end{cases}[/tex]

Step-by-step explanation:

The y-intercept (when x = 0) on the quadratic graph is 3, the upper quadratic graph does not intersect the x-axis, and the endpoint of the function has an open circle that stops at x = 1. The starting point extends to the boundaries of the graph

Therefore, the piecewise function shown in the quadratic graph is given as follows;

f(x) = x² + 3; x < 1

The straight line graph has a negative slope and starts at x = 1, with a closed circle, extending to higher values of x to the boundaries of the graph

Two points on the straight line graph are (1, 3) and (5, -5), therefore, the slope is (-5 - 3)/(5 - 1) = -2

The equation of the function is y - 3 = -2·(x - 1)

∴ y = f(x)  -2·x + 2 + 3 = -2·x + 5

f(x) = -2·x + 5; x ≥ 1

Answer:

s=9

d=6

Step-by-step explanation:

s+d=15

3.s+5.d=57

⇒s=9 và  d=6

The sum of A, B, C, and E is 23. Let's set up a system of equations based on the given information: s: number of single-scoop cones

d: number of double-scoop cones

1. The coach bought 15 cones in total:

s + d = 15

2. The cost of a single-scoop cone was $3 and the cost of a double-scoop cone was $5, and the total payment was $57:

3s + 5d = 57

Now, let's find the values of s and d by solving the system of equations.

First, we can use the first equation to solve for s in terms of d:

s = 15 - d

Now, substitute this value of s into the second equation:

3(15 - d) + 5d = 57

Now, solve for d:

45 - 3d + 5d = 57

2d = 57 - 45

2d = 12

d = 6

Now that we have the value of d, we can find the value of s using the first equation:

s = 15 - d

s = 15 - 6

s = 9

So, the number of single-scoop cones (s) is 9, and the number of double-scoop cones (d) is 6.

Now, let's find the sum of A, B, C, and E:

A: The number of single-scoop cones (s) is 9.

B: The number of double-scoop cones (d) is 6.

C: The cost of a single-scoop cone is $3.

E: The cost of a double-scoop cone is $5.

A + B + C + E = 9 + 6 + 3 + 5 = 23

So, the sum of A, B, C, and E is 23.
