GEOMETRY PLEASE HELP!!! What is the surface area of the square pyramid shown if the height is 15 m?

9514 1404 393

Answer:

  20, 50

Step-by-step explanation:

Let x and y represent the two numbers.

  x + y = 70 . . . . . . their sum is 70

  2x +10 = y . . . . . . one is 10 more than twice the other

Using the second equation to substitute for y in the first equation, we have ...

  x + (2x +10) = 70

  3x = 60 . . . . . . . . . subtract 10

  x = 20 . . . . . . . . . divide by 3

  y = 70 -20 = 50 . . . find the other number

The two numbers are 20 and 50.

Answer:

(x - 5)² + (y + 13)² = 121

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (5, - 13 ) and r = 11 , then

(x - 5)² + (y - (- 13))² = 11² , that is

(x - 5)² + (y + 13)² = 121

Answer:the law of sines is the relationship between the sides and angles of the ratio of the length of a side of triangle to the sine of the angle opposite that side is the same for all sides and angles in a given triangle

Step-by-step explanation:

Answer:

X=$96

Y=$19

Step-by-step explanation:

x=4y+20

X+Y=$115

4Y+20+Y=$115

5Y+20=$115

-20 -20

5Y=$95

/5 /5

Y=$19

X=4 x $19 + $20

X=$76+$20

X=$96

In linear equation,  cost of calculator = $96 , cost of textbook = $19 is the   cost  of each item .

What are instances of linear equations?

let cost of calculator = x

cost of textbook = y

x=4y+20  .................(1)

X+Y= 115  .................(2)

put value of equation 1 in 2

4Y+20+Y= 115

5Y+20= 115

5Y = 115 - 20

5Y =  95

Y = 95/5

Y = 19

Put value of y in equation 1

X=4 x 19 + 20

X= 76+ 20

X= 96

cost of calculator = 96

cost of textbook = 19

Answer:

17. 25 [tex]in^2[/tex]

18. 53 [tex]m^2[/tex]

19. 21.6 [tex]cm^2[/tex]

20. 20.8 [tex]km^2[/tex]

Step-by-step explanation:

The area of a parallelogram is simply the base multiplied by the height.

17.

Base = 5 in

Height = 5 in

Area = Base * Height

Area = 5 * 5

Area = 25 [tex]in^2[/tex]

18.

Base = 10 m

Height = 5.3 m

Area = Base * Height

Area = 10 * 5.3

Area = 53 [tex]m^2[/tex]

19.

Base = 5.4 cm

Height = 4 cm

Area = Base * Height

Area = 5.4 * 4

Area = 21.6 [tex]cm^2[/tex]

20.

Base = 5.2 km

Height = 4 km

Area = Base * Height

Area = 5.2 * 4

Area = 20.8 [tex]km^2[/tex]

Answer:

Well It would about 1/10000000 if your talking about all colors, but its not specified how many blue regions other colored regions there are so I cant tell you without knowing.

Step-by-step explanation:

Just Take the amount of regions then put it under the amount of Blue regions there are then look up on a browser, Ex: What is 2/3 into a percent: 66.6 percent, And you have your answer :)

Answer:

15/17

Step-by-step explanation:

Answer:

x = 14.5

Step-by-step explanation:

This is a supplementary angle, meaning the sum of the angles is 180°.

We can find the value of x by combining like terms.

5x - 6 + 7x + 12 = 180.

5x and 7x are alike.

5x + 7x = 12x.

-6 + 12 = 6.

The final equation is 12x + 6 = 180.

We can solve this by subtracting 6 from 180.

180 - 6 = 174.

12x = 174

Lastly, we divide 174 by 12.

174 / 12 = 14.5

Therefore, x is equal to 14.5

Step-by-step explanation:

1) Attached

2) Probability of the second ball is yellow is

P(2nd ball is yellow ) = Probability 2nd ball s yellow (if the first one was black) + Probability 2nd ball s yellow (if the first one was Yellow)

P(2nd ball is yellow ) = 0,204 + 0,045

P(2nd ball is yellow ) = 0,249

The firm's fixed-charge coverage ratio is 7.89 times

Explanation:

Fixed charge coverage ratio : This ratio deals with fixed payments like: interest payments, lease payments which is before earning before income and taxes.

The formula to compute the fixed charge coverage ratio is shown below:

= (EBIT + Fixed charges) ÷ (Fixed charges + interest expense)

= ($400,000 + $50,000) ÷ ($50,000 + $7,000)

= $450,000 ÷ $57,000

= 7.89 times

The total of fixed charge include depreciation expense also. Thus it would not be taken into computation part.

Hence, the firm's fixed-charge coverage ratio is

Answer:

A. 1 hour and 16 minutes

Step-by-step explanation:

There are 250 mL of D5W infusing at 33 gtt/min on IV tubing calibrated at 10 gtt/mL.  Calculate the infusion time.

select "No IV pump"

volume = 250 mL

rate = 33 gtt/min

calibration = 10 gtt/mL

Actual formula:

250 /( 33 gtt/min

10x  60)= 1.26 Hours

0.26 x 60 = 16 minutes

So 1.26 Hours = 1 Hour & 16 minutes

Answer:

At the end of the mortgage, $ 293,125 will have been paid.

Step-by-step explanation:

Given that Kaila wants to borrow $ 175,000 for her mortgage, and Timberwolf Bank offers a 15-year mortgage at an APR of 4.5%, to determine the amount to be repaid after the end of the mortgage, the following calculation must be performed:

175,000 x (1 + 15 x 4.5 / 100) = X

175,000 x (1 + 67.5 / 100) = X

175,000 x (1 + 0.675) = X

175,000 x 1,675 = X

293.125 = X

Therefore, at the end of the mortgage, $ 293,125 will have been paid.

Answer:

(-4, -2).

Step-by-step explanation:

Compare y = (1/2)(x + 4)^2 – 2 to the standard equation:

                y =    a(x - h)^2 + k       whose vertex is at (h, k).  

We see that h = -4 and k = -2.  Thus, the vertex of the vertex of the given parabola are (-4, -2).
