A running track design is composed of two half circles connected by two straight-line segments. Garrett is jogging on the inner lane (with radius r) while Devin is jogging on the outer (with radius R). If r= 30 meters and R= 33 meters, how much longer does Devin have to run to complete one lap?​

Answer:

i dont knoe

Step-by-step explanation:

Answer:

X Values

∑ = 53.5

Mean = 10.7

∑(X - Mx)2 = SSx = 151.086

Y Values

∑ = 6.9

Mean = 1.38

∑(Y - My)2 = SSy = 3.788

X and Y Combined

N = 5

∑(X - Mx)(Y - My) = 23.711

R Calculation

r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))

r = 23.711 / √((151.086)(3.788)) = 0.9911

So r= 0.9911 or 99.11%

Step-by-step explanation:

Total surface area is the sum of areas:

Correct choice is A

Answer:

Surface Area = (2)² + 4 × ½ × 2 × 3

Surface Area = 4 + 4 × ½ × 2 × 3

Surface Area = 4 + 2 × 2 × 3

Surface Area = 4 + 12

Surface Area = 16 in²

Step-by-step explanation:

y=kx

say that y is the original prince and x is the sale price

15=k(10)

15/10=k

3/2=k

you can check with the next problem to check if it is the same

25=k(20)

25/20=k

5/4=k

so you take 5/4-3/2=-1/4 so the constant is -1/4

Hope that helps :)

Answer:

( 2 4/5 * 1 3/10) * 1 1/2 = 5 23/50

Step-by-step explanation:

( 2 4/5 * 1 3/10) * 1 1/2 = 14/5 x 13/10 x 3/2 = 546/100 = 5 46/100 = 5 23/50

Answer:

7.5%

Step-by-step explanation:

86 - 80 / 80 = 0.075

so 7.5%

The percentage increase in wages of from last year to now is 7.5%.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, last year janes wages were $80 per week her wages are now $86 per week.

Now, the difference in wage =86-80

= 6

The percentage increase

= 6/80 ×100

= 7.5%

Therefore, the percentage increase in wages of from last year to now is 7.5%.

Answer:

Geometric sequence

[tex]a_{10} = 524288[/tex]

Step-by-step explanation:

Given

[tex]a: 2,8,32,128...[/tex]

Solving (1): The type of sequence

To check for arithmetic sequence:

[tex]d = a_2 - a_1[/tex] --- common difference

[tex]d = 8 - 2 = 6[/tex]

[tex]d =a_3 - a_2[/tex]

[tex]d =32-8=24[/tex]

Both values of d are not the same; Hence, the sequence is not arithmetic

To check for geometric sequence:

[tex]r = \frac{a_2}{a_1}[/tex] --- common ratio

[tex]r = \frac{8}{2}=4[/tex]

[tex]r = \frac{a_3}{a_2}[/tex]

[tex]r = \frac{32}{8} = 4[/tex]

[tex]r = \frac{a_4}{a_3}[/tex]

[tex]r = \frac{128}{32} = 4[/tex]

All values of r are the same.

Hence, it is a geometric sequence

Solving (2): Find [tex]a_{10[/tex]

For a geometric sequence;

[tex]a_n = a_1 * r^{n-1[/tex]

[tex]a_{10} = 2 * 4^{10-1[/tex]

[tex]a_{10} = 2 * 4^9[/tex]

[tex]a_{10} = 524288[/tex]

Answer:

x=1.033

Step-by-step explanation:

468=(240+225x)

228=225x

x=1.033

Answer:

468 = (16 + 15 X ) 15 ?

Step-by-step explanation:

468 = 240 + 225x

468-240=225 X

228=225x

228/225= X

1.01 = X

i think this is the. answer to ur question

Given:

The four table of values.

To find:

The table whose linear function has slope 2.

Solution:

Slope formula:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Consider any two points from each table and find the slope for each table.

For table 1, the two points are (2,1) and (6,-1). So, the slope of the linear function is:

[tex]m=\dfrac{-1-1}{6-2}[/tex]

[tex]m=\dfrac{-2}{4}[/tex]

[tex]m=\dfrac{-1}{2}[/tex]

For table 2, the two points are (0,8) and (2,4). So, the slope of the linear function is:

[tex]m=\dfrac{4-8}{2-0}[/tex]

[tex]m=\dfrac{-4}{2}[/tex]

[tex]m=2[/tex]

For table 3, the two points are (-4,4) and (-2,5). So, the slope of the linear function is:

[tex]m=\dfrac{5-4}{-2-(-4)}[/tex]

[tex]m=\dfrac{1}{-2+4}[/tex]

[tex]m=\dfrac{1}{2}[/tex]

For table 4, the two points are (-2,0) and (0,4). So, the slope of the linear function is:

[tex]m=\dfrac{4-0}{0-(-2)}[/tex]

[tex]m=\dfrac{4}{2}[/tex]

[tex]m=2[/tex]

Table 4 is the only table that represents a linear function whose slope is 2.

Therefore, the correct option is 4, Table 4.

Answer:

y = -12

Step-by-step explanation:

-4 (8+3y) = 112

-32 -12y = 112

-12y = 144

y = -12

Answer:

-4(8+3y)=112

-32-12y=112

-12y=112+32

-12y=144

y=144÷-12

y=12

Answer:

Based on the line plot picture that is attached below it can be calculated that a total of 15 students spent 5 or more hours last week reading. This can be easily calculated by adding all the x's on the marks of 5 hours or more. With both the boys and girl students combined the tally was the following

5 hours : 4 students

6 hours : 1 student

7 hours : 3 students

8 hours : 3 students

9 hours : 0 students

10 hours: 2 students

11 hours : 2 students

12 hours : 0 students

Step-by-step explanation:

Answer: B

its B because the line shows how much 5 were there and there was 2 dots

Answer:

37

Step-by-step explanation:

Pythagorean theorem

Answer: 37 (side AB)

Step-by-step explanation:

For this question you would have to use Pythagoras' theorem. Pythagoras' theorem states that c²=a²+b².

so when you put the numbers in the formula you get c²=12²+35²

12²=144

35²=1225

c²=144+1225

c²=1369

Then because you want c on it's own you square root 1369.

c=√1369

c=37

Hope this helps :)

Answer:

Step-by-step explanation:

The equation of a line with slope of m and y-intercept of b is: y = mx + b

b = 2 and line contains the point (4, -9), so:

-9 = m×4 + 2          {subtract 2 from both sides}

-11 = 4m                   {divide booth sides by 4

m = -¹¹/₄
