(-2.2) · (-2) · (–1) · (5) = ?
1. 88
2. 5 1/2
3. -88
4. -5 1/2

Answer:

The constant of porportionality is k = 12.5; the equation that describes the relationship is y = 12.5x.

Step-by-step explanation:

When you divide the miles by the hours, it's always 12.5, meaning that k must be 12.5.

If x is the hours and k is 12.5, the equation that describes the relationship is y = 12.5x.

What is square root ?

In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x. For example, 4 and −4 are square roots of 16, because 4² = ² = 16. The square root of any number can be expressed using the formula: √y = y½. In other words, if a number has 1/2 as its exponent, it means we need to find the square root of the number.

Given,

[tex]\sqrt{128}[/tex]

we divide the number 128 by 2 four times, we get

= [tex]\sqrt{8*2*2*2*2}[/tex]

= 2*2[tex]\sqrt{8}[/tex]

=4      [tex]\sqrt{8}[/tex]

Therefore, 4      [tex]\sqrt{8}[/tex] is the correct answer

Answer:

Step-by-step explanation:

So you need to take two points off the graph. (x,y) and (x,y)

After that use those points to plug it into this equation

your gonna want to take the Y points from both and subtract from each other.

Do the same for the X points.

Y2-Y1

X2-X1

You'll then divide The Y by the X and that the Rise over Run.  When you graph that. That'll be your answer.

Answer:

(28 - 11.5) ÷ 5.5

Step-by-step explanation:

So let's examine this question.

We have already payed $11.50 the rent the canoe, so we have $16.50. Divide that by $5.50, and you get 3. So, 3 hours.

Now for the expression.

You start out with $28. You subtract $11.50 from it because it is being used to rent the canoe. You then divide your answer by $5.50 to determine how many hours you can use the canoe for.

Hmm.

(28 - 11.5) ÷ 5.5 = h

(28 - 11.5) ÷ 5.5 = 3

Answer:

40.021

Step-by-step explanation:

Unlimited calls = $40

Text message = $0.021

NOTE:There is a difference between the value you gave for cost of text messages in the question and the values given in the group of answers. I will use $0.021 for cost of text messages since it is common to all answer choices.

Total cost = Cost of unlimited calls + cost of text messages

C = $40 + $0.021

= $40.021

Therefore, the equation which represent the total cost in dollars for a month is 40.021

A. 40.021

Answer:

x = 45

Step-by-step explanation:

[tex]540 + 6x = 810[/tex]

Step 1 : Collect like terms

[tex]6x = 810 - 540[/tex]

Step 2 : Simplify

[tex]6x = 270[/tex]

Divide both sides of the equation by 6

[tex] \frac{6x}{6} = \frac{270}{6} [/tex]

Step 4 : Simplify

[tex]x = 45[/tex]

I hope it helps :)

Answer:

Well...X=45

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:540+6*x-(810)=0

Pull out like factors :-270 + 6x  =   6 • (x - 45)

Solve  :    x-45 = 0::

Add  45  to both sides of the equation:  x = 45

Step-by-step explanation:

Answer:

Perimeter = A + B + C

Perimeter = 35

A = 2x

B = x+4

C = 13

35 = A + B + C

Step-by-step explanation:

35=2X+X+4+13

SUBTRACT 17 FROM EACH SIDE

18+3X

DIVIDE EACH SIDE BY THREE

X=6

Step-by-step explanation:

Given:

Total number of jewels = 1000

Emeralds = 600

Sapphires = 300

Rubies = 100 rubies

100 jewels she took randomly.

To find:

The probability that all 100 jewels she took were sapphires.

Solution:

Number of selected jewels = 100

Total number of jewels = 1000

We have to select 100 out of 1000.

So, the total number of outcomes [tex]=^{1000}C_{100}[/tex]

Number of sapphires = 300

We have to select 100 out of 300 sapphires .

So, the favorable outcomes [tex]=^{300}C_{100}[/tex]

Now,

[tex]\text{Required probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

[tex]\text{Required probability}=\dfrac{^{300}C_{100}}{^{1000}C_{100}}[/tex]

Therefore, the required probability is [tex]\dfrac{^{300}C_{100}}{^{1000}C_{100}}[/tex].

Step-by-step explanation:

First off the slope is negative and it decreases by one unit each time.

Step-by-step explanation:

The answer is

Distance is 42000 kmph

The distance the rocket has traveled after 1 hour with a speed of 700km/hour is 700 km.

Given,

A rocket is launched from the launch pad at a speed of 700 km/hr.

We need to find how far will the rocket has traveled after 1.0 hr.

Speed is the ratio of distance per time.

Speed = Distance /Time

Its unit is km/hour or m/second.

We have,

Speed = 700 km/h

Distance = D

Time = 1 hour

From the speed formula:

Speed = Distance / Time

700 = Distance / 1

700 km / hour x 1 hour = Distance

Distance = 700 km

Thus the distance the rocket traveled after 1 hour with a speed of 700km/hour is 700 km.
