Could someone help please? Thanks for your time!

Answer:

You can cross multiply for this problem. So:

[tex]\frac{6}{10}=\frac{21}{K}\\6K=210\\K=35[/tex]

So K=35!

Hope this helps! :)

Step-by-step explanation:

Flat rate is the y- intercept b = 11.2

Charge per mile is the slope m = 3.1

The equation is:

Answer:

x = 3.5

x = 0.1

x = 4

x = 20

(In order top to bottom)

Step-by-step explanation:

2(x) = 7

/2     /2

x = 3.5 (1st one)

60(x) = 6

/60    /60

x = 0.1 (2nd one)

12(x)=48

/12    /12

x = 4 (3rd one)

1/20(x)=1

x20    x20

x = 20 (4th one)

Equations:

1. 2 • x = 7

2. 60 • x = 6

3. 12 • x = 48

4. x • 1 over 20 = 1

Value of x (Answers):

1. 3.5

2. 0.1

3. 4

4. 20

Explanations:

For number 1;

7 ÷ 2 = 3.5

3.5 • 2 = 7

Therefore, 3.5 is your answer for number 1.

For number 2;

6 ÷ 60 = 0.1

0.1 • 60 = 6

Therefore, 0.1 is your answer for number 2.

For number 3;

48 ÷ 12 = 4

4 • 12 = 48

Therefore, 4 is your answer for number 3.

For number 4;

1 over 20 = 0.05

1 ÷ (1 over 20) = 20

20 • 1 over 20 = 1

Therefore, 20 is your answer for number 4.

Step-by-step explanation:

I think this is the only way to prove it in one reason

Answer:

(Go with the melon, tomato, or pumpkin)

Step-by-step explanation:

MELON: I chose the melon. The target is 40ft away, so the maximum height of the launch has to be 12 feet.

TOMATO: I chose the tomato (because the numbers are round and easy to manipulate) The target is 60ft away, so the maximum height of the launch has to be 45 feet.

PUMPKIN: I chose the pumpkin. The target is 50 ft away, so the maximum height is 62 feet.

Answer:

44

Step-by-step explanation:

Isosceles triangles have two angles that are equal.  If the two equal angles are 68

We have  68, 68, and an unknown angle x

They add to 180

68+68+x = 180

136+x=180

x =180-136

x =44

Since y is inversely proportional to [tex]x^2[/tex], the value of y, when x = 10 is 4.

Given the following data:

To find the value of y, when x = 10:

Mathematically, translating the inverse relationship between x and y, we have:

[tex]y \;\alpha\; \frac{1}{x^2} \\\\y \;= \frac{k}{x^2}[/tex]

Substituting the given parameters into the formula, we have;

[tex]16 = \frac{k}{5^2} \\\\k = 16 \times 25[/tex]

k = 400

Now, we can find the value of y, when x = 10:

[tex]y = \frac{400}{10^2} \\\\y = \frac{400}{100}[/tex]

y = 4

Answer:

233.4 Centimeters

Step-by-step explanation:

48 x 10 = 480

48 x 4 = 192

480 + 192 = 672

139 x 10 = 1390

139 x 2 = 272

1390 + 272 = 1662

1662 + 672 = 2334

2334mm = 233.4cm

Answer:

[tex]t=4.4594[/tex]

Step-by-step explanation:

We can take the log 2 of both sides to get [tex]t=\log_2(22)[/tex].

We know that [tex]2^4<22<2^5[/tex], so [tex]4<t<5[/tex].

So, the solution is [tex]\boxed{t=4.4594}[/tex] because it's the only answer that works.

Answer:

See attached photograph

Step-by-step explanation:

It is a simple matter of subtracting 1 from the given x value. For example, when x=3 we need to subtract 1 away from it to find f(x); so, f(x)=2.

Side note: the term "f(x)" means "y", so when plotting this information on a graph, you will use the f(x) column as your y value.

Step-by-step explanation:

12 shots in 5 minutes.

12/5 ratio.

how long for 5 shots ? x minutes

5/x must be the same ratio as 12/5

so,

5/x = 12/5

25/x = 12

25 = 12x

x = 25/12 = 2 1/12 ≈ 2.08 minutes =

= 2 minutes and 5 seconds

Answer:

Yes

Step-by-step explanation:

Because any vertical line drawn doesn't meet the graph at two points.

So this concludes that there is a single output for any input. Which is the basic requirement for a function

9514 1404 393

Answer:

  1 < x < 29

Step-by-step explanation:

The triangle inequality requires the sum of the two shortest sides exceed the longest side.

When x and 14 are the shortest:

  x + 14 > 15

  x > 1

When 14 and 15 are the shortest:

  14 +15 > x

  29 > x

Then the requirement for the length of x is ...

  1 < x < 29

The length of the third side of a triangle can be between the difference and sum of the two given sides.

Answer:

Based on the graphs shown, what would you conclude about the conditions under which enzymes function in cells?

A

Enzymes are most effective at a particular pH and temperature but can function over a range of pH and temperature.

B

С

Enzymes do not have a specific pH or temperature at which they are most effective but function optimally over a range of pH and temperature.

Enzymes work equally well at the low and high ends of their temperature range but reaction rate drops quickly at the high end of their pH range

Enzymes only function at a specific pH and temperature and cannot function over a range of pH or temperature.
