Answer:

B

Step-by-step explanation:

all you need to do for this is multiply the numerator by the 3.

3/4 times 3 = 9/4-  thats not more than 3

3/2 times 3 = 9/2 - thats more than 3  

1/12 times 3 = 3/12-  thats  not more than 3

9/10 times 3 = 27/10 thats  not more than 3

Answer:

Step-by-step explanation:

You have to use the tangent.

Tan(y) = opposite / adjacent

tan(10) = x / 500

tan(10) = 0.1763

0.1763 = x / 500

500 * 0.1763 = x

x = 88.1635

x = 88.2

Answer:

Total cost= $5,425

Step-by-step explanation:

Giving the following information:

Month Machine _Hours Amount

January 200 $2,800

February 350 3,000

March 450 4,000

April 500 5,000

May 600 5,200

June 580 5,800

First, we need to calculate the fixed and variable costs. To do it, we will use the high-low method:

Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)

Variable cost per unit= (5,800 - 2,800) / (600 - 200)

Variable cost per unit= $7.5 per hour

Fixed costs= Highest activity cost - (Variable cost per unit * HAU)

Fixed costs= 5,800 - (7.5*600)

Fixed costs= $1,300

Fixed costs= LAC - (Variable cost per unit* LAU)

Fixed costs= 2,800 - (7.5*200)

Fixed costs= $1,300

Now, we can determine the total cost for 550 hours:

Total cost= 1,300 + 7.5*550

Total cost= $5,425

Answer:

80 minutes

35.2 km

Step-by-step explanation:

You can't give more than the 6 points you have allocated. If I am the only person answering, you have to come back to award the Brainliest -- it varies how much time. Usually 2 or 3 days. Few people do.

The answer to this question depends on you understanding that both girls will be side by side when the second one catches the first. So the distances will be equal

That means that

.44t = 35t + 7.2                     Subtract 0.35t  from both sides

0.44t - .35t = 7.2      

0.09 t  = 7.2                          Divide

t = 7.2/0.09

t = 80 minutes

How far apart are they from the starting point?

d = 0.44t

d = 0.44 * 80

d = 35.2 km from the starting point.

Answer:

  72.6 cm

Step-by-step explanation:

It is the perimeter of the overall rectangle plus twice the depth of the notch.*

  P = 2(L+W) +2d

  P = 2(16 cm + 13 cm + 7.3 cm) = 2(36.3 cm)

  P = 72.6 cm

The perimeter of the shape is 72.6 cm.

_____

* You may be able to visualize this if you imagine the bottom (top) of the notch translated out (down) to the edge of the rectangle. That translation does not affect the length of the line segment, but helps convince you that only the two legs of the notch are added to the perimeter of the rectangle.

Answer:

-13-x(3)

Step-by-step explanation:

Hope this helps :)

The expression in the mathematical form will be 3x + 13.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Negative thirteen decreased by 3 times a number. Then the expression in the mathematical form is given as,

Let x be the number. Then the expression will be

⇒ 3x - (-13)

⇒ 3x + 13

The expression in the mathematical form will be 3x + 13.

Answer:

  d)  14,238

Step-by-step explanation:

Suppose the smaller number is n. If the larger number gives the smaller when it is divided by 10, then the larger number is 10n. The sum of the two numbers is ...

  n + 10n = 11n = 17402  ⇒  n = 17402/11

The difference of the two numbers is ...

  10n -n = 9n = (9)(17402/11)

This means the difference of the two numbers is 9/11 of the sum, so is ...

  (9/11)(17402) = 14,238 . . . . matches D

Answer:

0.2690 kg

Step-by-step explanation:

Given that:

For cutting a 4.5 kg block of cheese; the standard deviation:

[tex]S_x = 0.1 \ kg[/tex]

For a large no of blocks,  at 95% confidence level;

Using the t table; where the degree of freedom is infinity or > 30

t-distribution (t) = 2

∴

[tex]P_x = tS_x[/tex]

[tex]P_x = 2 \times 0.1[/tex]

[tex]P_x = 0.2 \ kg[/tex]

The system uncertainty as a result of the accuracy [tex]B_x[/tex] is:

[tex]B_x = 1.5\% \ of \ reading[/tex]

[tex]B_x = (\dfrac{1.5}{100})(12 kg)[/tex]

[tex]B_x = 0.18 \ kg[/tex]

The total uncertainty  for a single experiment with a 95% confidence interval will be:

[tex]w_s = ( B_x^2 + P_x^2)^{\frac{1}{2}[/tex]

[tex]w_s = (0.18^2 + 0.2^2)^{\frac{1}{2}[/tex]

[tex]\mathbf{w_s = 0.2690 \ kg}[/tex]

Answer:

It means that if we select a random point around the globe, there is a 70% = 0.7 probability that it represents water.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

We know, that the planet Earth is formed 70% by water, and the globe represents this. This means, as the statement says, the if we select a random point around the globe, there is a 70% = 0.7 probability that it represents water.
