Answer:

C. 58.18 mph

Step-by-step explanation:

Answer:

C. 58.18

Step-by-step explanation:

The average speed means we will do miles per hour (mph). So if there are 640 miles for 11 hours the fraction would look like this:

640/11

We want to find the value for 1 hour so we need the bottom number(denominator) to be 1

Therefore we divide by 11 on the numerator and denominator by 11

58.181818(repeating)/1

This means we travel 58.181818... miles per hour.

If we round to the hundredths place we get 58.18 or option C.

Keep in mind that we can do this in ratio form and still get the same answer:

miles: hours

640:11

58.181818:1

Answer:

a. 10v/(v² - 16) b. 3 hours

Step-by-step explanation:

a. Write and simplify an equation for the amount of time t in hours it will take the cyclist to make the trip.

Let v be the speed of the cyclist without the wind. The speed of the cyclist with the 4 mile per hour wind in the direction of the wind is v' = v + 4. Since the distance travelled is 5 miles, and time, t = distance/speed, the time it takes to make this trip is t' = 5/(v + 4)

Let v be the speed of the cyclist. The speed of the cyclist with the 4 mile per hour wind against the direction of the wind is v" = v - 4. Since the distance travelled is 5 miles, and time, t = distance/speed, the time it takes to make this trip is t" = 5/(v - 4).

So, the total travel time, T = t' + t"

= 5/(v + 4) + 5/(v - 4)

= [5(v - 4) + 5(v + 4)]/[(v + 4)(v - 4)]

= [5v - 20 + 5v + 20)]/(v² - 4²)

= 10v/(v² - 16)

b. What is the cyclist's total travel time, if she travels an average of 6 miles per hour without the wind?

If v = 6 miles per hour, then

T = 10v/(v² - 16)

= 10(6)/(6² - 16)

= 60/(36 - 16)

= 60/20

= 3 hours

delta math said it lol

Answer:

yes I can

Step-by-step explanation:

1/9÷2/5

=0.011111111111

=1⁄90

Let x = 0.555…

Then 10x = 5.555…

Subtract one from the other to get

10x - x = 5.555… - 0.555…

Notice how the fractional parts on the right cancel. This leaves you with

9x = 5

and so

x = 5/9

Answer:

59

Step-by-step explanation:

Since this fraction repeats the same number it must have a denominator of 9 and a numerator of the repeating digit the repeating digit is 5 so the fraction is 59

Step-by-step explanation:

Answer:

Jan spent 3 months at the first gym and 9 months at the second gym.

Step-by-step explanation:

Given that:

1 year = 12 months

x = months at gym one

y = months at other gym

According to given statement;

x+y=12      Eqn 1

85x+50y=705     Eqn 2

Multiplying Eqn 1 by 50

50(x+y=12)

50x+50y=600     Eqn 3

Subtracting Eqn 3 from Eqn 2

(85x+50y)-(50x+50y)=705-600

85x+50y-50x-50y=105

35x=105

Dividing both sides by 35

[tex]\frac{35x}{35}=\frac{105}{35}\\x=3[/tex]

Putting x=3 in Eqn 1

3+y=12

y=12-3

y=9

Hence,

Jan spent 3 months at the first gym and 9 months at the second gym.

Answer:

  (d)  80y⁶ -10y³

Step-by-step explanation:

You only need to find the highest-degree term of the product to determine the correct answer choice.

That term is the product of the highest-degree terms of the factors:

  (-8y³)(-10y³) = 80y⁶

This matches choice D only.

Step-by-step explanation:

p = 2(L+W)

98 < 2(x-2cm + 3x+5cm)

98 < 2x - 4 + 6x + 10

98 < 2x + 6x -4 +10

98 < 8x + 6........the inequality

98 - 6 < 8x

92 < 8x

11.5 < x.......the value of x

Answer:

$82.5

Step-by-step explanation:

Step one:

Given that the percent of which is 10% amount to $8.25

We can estimate the of the Jeans as

Step two

Let the cost be x

10 percent of x= 8.25

10/100*x=8.25

0.1x=8.25

Divide both sides by 0.1 to get the value of x

x=8.25/0.1

x=$82.5

The cost of the jeans is

$82.5

Answer:

is it 42

Step-by-step explanation:

Answer:

increase = 59-50

increase = $9.00

Percent = (increase/whole value) x 100

Percent = (9/50) x 100

Percent  = 18%

Given:

The arithmetic sequence is −15, −33, −51, −69.

To find:

The nth term of the arithmetic sequence.

Solution:

We have,

−15, −33, −51, −69

Here,

First term: a = -15

Common difference is

[tex]d = -33-(-15)[/tex]

[tex]d = -33+15[/tex]

[tex]d = -18[/tex]

Now, nth term  of an arithmetic sequence is

[tex]a_n=a+(n-1)d[/tex]

Substitute a=-15 and d=-18.

[tex]a_n=-15+(n-1)(-18)[/tex]

[tex]a_n=-15-18n+18[/tex]

[tex]a_n=-18n+3[/tex]

Therefore, the nth term of the given arithmetic sequence is [tex]a_n=-18n+3[/tex].

Answer:

x=3.4

y=-6.75

Step-by-step explanation:

5x+4y=-10  (equation 1 )

-5x+3y=-17  (equation 2)

7y=-27

y=-6.75

substitution (equation 1 ) y=-6.75

5x-27=-10

5x=17

x=3.4

Answer:

B

Step-by-step explanation:

Answer:

2 wholes and 5/26

Step-by-step explanation:

convert the mixed number to improper fraction

= -19/6 / -13/9

since there is 2 negatives and (-)/ (-) means your answer is positve

to divide by a fraction multiply by the reciprocal of that fraction.

19/6 x 9/13

reduce 6 and 9 to 3 and 2 becuase both have a GCF of 3.

19/2 x 3/13

multiply 19/2 x 3/13

= 57/26

= 2 wholes and 5/26

= 2.1923076

Answer:

In a linear equation in x and y, x is called x is the independent variable and y depends on it. We call y the dependent variable. If the variables have other names, yet do have a dependent relationship, the independent variable is plotted along the horizontal axis

:)

Answer:

This should be considered a linear substitution because you can substitute this equation into y in another linear equation to find the answer or the solution to the linear equation
