A square barn has an area of 64 square meters. How long is each side?

Answer:

x = 18

y = 54

Step-by-step explanation:

90 - 72 = 18

18 + 2x = 3x

18 = x

2(18) = 36

3(18) = 54

72 + y + 54 = 180

126 + y = 180

y = 54

Answer:

54

Answer:

Price is $1088 (agrees with answer B)

Step-by-step explanation:

Notice that the linear equation that represents this relationship can be estimated via finding the slope and y-intercept using a couple of the given points on the plane (for example (5, 140), and (10, 200), which results in;

Price = 12 x + 80

where "x" is the number of computers shipped.

Then, to ship 84 computers, we have the following price:

Price = 12 (84) + 80 = 1088

Then the price is $1088.

Answer:

b = 7

Step-by-step explanation:

Add 4b to both sides

You then get -b = -7

You want to multiply both sides by -1 because you can't have a negative variable

Answer:

b = 7

Answer:1+3=4 4+2=6 5+6=11

Step-by-step explanation:

Answer:

1+3=4, 2+4=6, 5+6=11

Step-by-step explanation:

when made into a cube, (assuming 2 is on the top,) 1 is on the left side and 3 is on the right. 2 is on the top and 4 is on the bottom. 5 is on the north side (the front I guess, but north is the way I can explain it best) and 6 is on the south (the back).

Answer:

No single Correct answer. Both b and d will work

Step-by-step explanation:

You want to get rid of y.

The first equation has a 3 in front of the y

Therefore you would have to multiply the second equation by 3 or - 3

If you use -3 you would add the two equations

If you use 3 you would subtract the two equations.

It is either b or d. Both will give you the same answer.

- Three

  x + 3y =   10

-6x - 3y = - 15               Add

-5x = - 5                       Divide by - 5

x = -5/-5

x = 1

+ Three

x   + 3y =  10

6x + 3y = 15                   Subtract

-5x = - 5

x = -5/-5

x = 1                                Same thing.

hello :

2x+7y=1 ...(*)

y=4x−8...(**)

(4;8) means x= 4 and y= 8

put this values in (*) and(**) :

2(4)+7(8) =1           62=1    false

8=4(4)-8          8=8   true

so :(4;8)  is not solution for this system.

Answer:

500.000 cos it's firstly multiplies by 5

Answer:

1681

Step-by-step explanation:

In a four digit perfect square, the first two digits and last two digits taken seperately are also perfect squares.

Therefore, the answer is 1681 because 1681=41*41 and

16=4*4 and 81=9*9

Answer: 20/12

Step-by-step explanation: In order to get a 12 in the denominator

of 5/3, we multiply top and bottom of 5/3 by 4 to get 20/12.

So 20/12 is an equivalent fraction.

Step-by-step explanation:

y + 1 = -(x+5)

y + 1 = -x - 5

y = -x - 6

x + y = -6

Step-by-step explanation:

tan 26° = [tex]\frac{x}{90}[/tex] ⇒ x = 90tan26° ≈ 43.9 ft. (This answer for the picture)

sin 26° = [tex]\frac{h}{100}[/tex] ⇒ h = 100sin26° ≈ 43.9 ft (This answer for the text)

h = √(100² - 90²) ≈ 43.589 ft. (Pythagorean theorem)

Answer:

Regression equation is;

y = 0.2028x - 8.443

The predicted value is not at all close to the actual novel rate

Step-by-step explanation:

The internet users will be the x-values while the novel laureates will be the y-values.

Thus, sum of x values is;

Σx = 79.5 + 79.6 + 56.8 + 67.6 + 77.9 + 38.3 = 399.7

Sum of y values is;

Σy = 5.5 + 9 + 3.3 + 1.7 + 10.8 + 0.1

Σy = 30.4

Σx² = 79.5² + 79.6² + 56.8² + 67.6² + 77.9² + 38.3²

Σx² = 27987.71

Σy² = 5.5² + 9² + 3.3² + 1.7² + 10.8² + 0.1²

Σy² = 241.68

Σxy = (79.5 × 5.5) + (79.6 × 9) + (56.8 × 3.3) + (67.6 × 1.7) + (77.9 × 10.8) + (38.3 × 0.1)

Σxy = 2301.16

The regression line will be;

y = b1(x) + b0

b1 is expressed as;

b1 = [nΣxy - (Σx • Σy)]/[nΣx² - (Σx)²]

Where n is number of given data which is n = 6.

Thus;

b1 = [(6 × 2301.16) - (399.7 × 30.4)]/[(6 × 27987.71) - (399.7)²]

b1 = 1656.08/8166.17

b1 = 0.2028

b0 is expressed as;

b0 = [(Σy • Σx²) - (Σx • Σxy)]/[nΣx² - (Σx)²]

b0 = [(30.4 × 27987.71) - (399.7 × 2301.16)]/[(6 × 27987.71) - (399.7)²]

b0 = -68947.268/8166.17

b0 = -8.443

Thus, regression equation is;

y = 0.2028x + (-8.443)

y = 0.2028x - 8.443

Best predicted value is given as;

y¯ = (Σy)/n

y¯ = 30.4/6

y¯ = 5.067 per 10 million people.

The predicted value is far greater than the actual value of 2 per 10 million​ people.

Thus, we can say that the predicted value is nowhere close to the actual value
