The change in height ___ is
mile(s).

The entire descent lasts ___ hour(s).

Answer:

B

Step-by-step explanation:

Open circle: < or >

Arrows point outward

Points located at 5 and 18

Answer:

a

Step-by-step explanation:

Answer:

B=-1

Step-by-step explanation:

Standard form is Ax+By=C.

In this case, Ax is x, By is 1/5y, and C is +2.

To isolate the 2 (the C), subtract x from both sides of the equation:

x+2=1/5y

-x     -x

2=-x+1/5y.

Now, the value of B, the x value, is -1.

Answer:

[tex]n \geq -\frac{-29}{28}[/tex]

Step-by-step explanation:

[tex]-3(1 - 7n) \geq -32 - 8n\\-3 + 21n \geq -32 -8n\\[/tex]

       +8n               +8n

[tex]-3 + 28n \geq -32\\+3 +3\\28n \geq -29\\/28 /28\\n \geq \frac{-29}{28}[/tex]

Answer:

x > 6 and x ≤ 10

Step-by-step explanation:

You have to sleep for more than 6 hours, which means it is greater than and can not be equal to because it has to be more than 6 hours.

For the second problem, at most includes the 10th person so x is less than or equal to 10.

Hope this makes sense!!

Answer:

1. x > 6

2. x <= 10

Step-by-step explanation:

1. You want to sleep for more than 6 hours. If x equals amount of sleep, then x should be greater than 6.

2. You want at most 10 ppl. So, It can be equal to ten or less than ten ppl in the room.

Answer:

It is 7

Step-by-step explanation:

y = mx+b

y is the total cost.

x is the number of hours.

b : that's 16 dollars.

y = 9x+16

The problem states that the cost was 79 dollars.

Substitute that for y and solve for x.

79 = 9x+16

63 = 9x

x = 7 hours

Answer:

14

Step-by-step explanation:

2xL + 2x10 = 48

2xL + 20 = 48

2xL = 28

Answer:

The relation is a function because there isnt a repeating y

Answer:

y= -3x

Step-by-step explanation:

Answer:

You can put this solution

30.24 - 2.24 = $28 just tickets

$28/x = $/person

or

(30.24 - 2.24)/x

Step-by-step explanation:

Given parameters:

Number of sides of the regular body  = 10

      A decagon has 10 sides.

Unknown:

Sum of the measures of the interior angles = ?

Solution;

 To find the sum of the interior angles of a decagon; use the expression below:

             Sum of interior angles  =  (n - 2) x 180

where;

  n = number of sides;

So,

         Sum of interior angles  = (10 - 2) x 180 = 1440°

The sum of interior angle of a decagon is 1440°

Answer:

-34.2

Step-by-step explanation:

when u multiply those 2 numbers, it makes -34.2

Answer: G = 35.2

Step-by-step explanation: G - 6 x 5.7 = 1

G - 34.2 = 1

G = 1 + 34.2

G = 35.2

G = 176/5 , G = 35 1/5

Step-by-step explanation:

321 x 82

Answer:

26,322 is your answer.

Step-by-step explanation:

"The product" is referring to the answer of two numbers that have been multiplied together. Thus the problem is asking you to find [tex]321*82[/tex].

[tex]321*82=26322[/tex]

Answer:

B)15.5

Step-by-step explanation:

Answer:

Omg this is the third time i answered this question, The United States is 387.87 times larger than Columbus, Ohio.

Step-by-step explanation:

8.25 times 100000 = 825,000

3.2 times 100000000 = 320,000,000

320,000,000 divided by 825,000 = 387.87

3 + 5 = 8

3 - 5 = -2

-2 and 8

Answer:

0

Step-by-step explanation:

To solve this without L'Hopital's rule, you need to use this identity:

lim(x→0) (sin x / x) = 1

lim(x→0) (sin²x / x)

lim(x→0) (sin x / x) (sin x)

lim(x→0) (sin x / x) · lim(x→0) (sin x)

1 · 0

0

Alternatively, since plugging in x=0 gets 0/0, we can use L'Hopital's rule.  Replace the numerator and denominator with their derivatives.

lim(x→0) (sin²x / x)

lim(x→0) (2 sin x cos x / 1)

0

Answer:

rational because they end

Step-by-step explanation:

Answer:

27.5 and 11.5 are both rational numbers.

Step-by-step explanation:

This is because they do not continue on forever. You know what they are. So numbers like 1, 1.5, 1.234, and 100 are rational. Numbers like pi, 1/3 (1.33333 forever) are irrational.

B is the answer just took the test

Answer:

Three are 27 rows of saplings

Step-by-step explanation:

Since 21 saplings were left out of 750 saplings, the number of saplings arranged will be 750 -21 = 729 saplings

We were told that the number of saplings arranged per row is equal the number of rows

So let’s say the number of saplings arranged per row is x

Automatically, the number of rows too will be x

So the total number of saplings arranged will be;

x * x = x^2

This is equal to 729

x^2 = 729

x^2 = 27^2

Since power is equal, equate the base

This means that x = 27
