Answer:

50 cycles

Step-by-step explanation:

To find this out, we need to know how many cycles he sells a day. So as given he sells 5 cycles in 2 days, so what is half of five? While 2.5 cycles wouldn't make sense, lets use the variable to see what our answer would be approximately.

2.5 cycles x 20 days = 50 cycles.

So, in 20 days Josh would sell 50 cycles.

Answer:

50 cycles will be sold in 20 days

Step-by-step explanation:

2 days⇒5 cycles

1 day⇒5 divided by 2 days

20 days⇒5 cycles multiplied by 20 days divided by 2 days then the final answer is 50 cycles.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Answer:

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion. In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

Area of 1 side: 3*3=9

Number of sides: 6

6*9=54

Answer:

54 square yards

Step-by-step explanation:

This is a cube, as the width, height, and length are all the same. To fine the surface area of a cube, simply find the area of one side and multiply it by six, as a cube has six sides.

[tex]Area = Width*Height\\Area = 3 * 3\\Area = 9[/tex]

The area of one side of the cube is 9 square yards. Therefore, the surface area of the entire cube is 6 x 9 or 54 square yards.

Answer:

Step-by-step explanation:

You got it right: the point (0, -1) is another point on the graph of y = 3x - 1.

Substituting 0 and -1 back into the equation, y = 3x - 1:

-1 = 3(0) - 1

So the pint is also a solution to the equation.

Answer:

h = 1200 - 34t

Step-by-step explanation:

25 minutes, descend 850 feet, so each minute, descend 850/25 = 34 feet

after t minutes, descend 34*t feet,

starting at 1200 feet, so the height is h = 1200 - 34t

Answer:

Step-by-step explanation:

go DOWN 3 and side 1 so -3/1 or -3

Given that: √{11 + 4√(7)}

Let √{11 + 4√(7)} = √(x) + √(y)

Squaring on both sides then

= [√{11 + 4√(7)}]² = {√(x) + √(y)}²

= 11 + 4√(7) = x + y + 2√(xy)

= 11 + 2√(7 * 2²) = x + y + 2√(xy)

= 11 + 2√(7 * 2*2) = x + y + 2√(xy)

= 11 + 2√(7 * 4) = x + y + 2√(xy)

= 11 + 2√(28) = x + y + 2√(xy)

On comparing with both sides, we notice that:

⇛2√(xy) = 2√(28)

⇛ xy = 28

We know that

(x-y)² = (x+y)² - 4xy

(x-y)² = (11)² - 4(28)

(x-y)² = (11*11) - 112

(x-y)² = 121 - 112

(x-y)² = 9

x - y = √(9)

x - y = √(3*3)

On adding equation (1) and equation (2), we get

x + y = 11

(+) x - y = 3

_______

2x = 14

Shift the number 2 from LHS to RHS, changing it's sign.

⇛x = 14/2

⇛x = 7/1

Simplify the fraction to get the value of x.

Now, substitute the value of x in equation (1) then

x + y = 11

⇛7 + y = 11

Shift the number 7 from LHS to RHS, changing it's sign.

⇛y = 11 - 7

Now, we have: x = 7 and y = 4

So,

√(x) + √(y) = √(7) + √(4) = √(7) + √(2*2) √(7) + 2

(Or)

√{11 + 4√(7)}

= √{11 + 2√(7*4)}

= √{11 + 2√(7)√(4)}

= √[{√(7)²} + {√(4)}² + 2√(7)√(4)

[since, (a+b)² = a² + 2ab + b²]

= √[{√(7) + √(4)}²]

= √(7) + √(4)

= √(7) + √(2*2)

Therefore, √{11 + 4√(7)} = √(7) + 2

Answer: Hence, the simplified form of √{11 + 4√(7)} is √(7) + 2

Answer:

In order to find the slope, we would need to format the coordinates like rise over run (y/x)

We find two points, (-6, 12) and (-5, 14)

Now we subtract the y coordinates from each other and do the same for the x coordinates

14 and 12 are our y coordinates so that will be our rise

-5 and -6 are x coordinates so that will be our run
