josh sells 5 cycles in 2 days. after 20 days, how many cycles should be sold?

Answers

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.

Explanation:

The law of conservation of momentum states that in any isolated system (=no external forces acting on it), the total momentum is conserved. This is also valid, for example, for a system consisting of many particles colliding with each other: during each collision between two particles, the total momentum of the two particles is always conserved, even if the momentum of each particle

To find:-Actual length and width of rectangle

If the equation ar+b=cr + d has no solution, like in the example below, what must be true about a b c and d?

Answers

Answer:

See below.

Step-by-step explanation:

For an equation like [tex]\displaystyle \large{ar+b=cr+d}[/tex] to have no solution, the equation has to be false.

To make an equation false, we let a = c. That’d make a and c have same value, when we transport cr to subtract ar, we’ll get 0.

So if a = c, the equation is [tex]\displaystyle \large{b=d}[/tex] now that we have b = d. The equation has to be false to have no solutions, hence b and d must not equal to one another.

Summary

When a = c, the new equation is b = d as ar and cr having same value, when subtracted, the remain is 0+b=d.b = d means that the value of b and d are equal but that makes the solutions to be infinitely many. Therefore, we cannot let b = d.From second, b ≠ d.a = c but b ≠ d

Find the surface area of this shape.

Answers

Answer:

54 yds²

Step-by-step explanation:

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.

√(11 +4 √7)
hi, brainly helper please solve this ASAP. Thank​

Answers

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:

⇛x + y = 11 →→→→Eqn(1)

⇛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)

Therefore, x - y = 3 →→→→Eqn(2)

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.

Therefore, x = 7

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

Therefore, y = 4

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

So,

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

(Or)

Short Method:

√{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

Answers

Answer:

Consistent independent

x + y = 0  and  -x + y = -8

Step-by-step explanation:

Inconsistent: parallel lines, no solutions

Consistent dependent: same line, infinite solutions

Consistent independent: intersects at one point, one solution

Therefore, the pair of lines are Consistent independent

From inspection of the diagram:

One line has a negative slope and the other a positive slope.

One has a y-intercept of 0 and the other a y-intercept of -8.

Therefore, the solution is x + y = 0  and  -x + y = -8

Because:

x + y = 0  ⇒  y = -x  (neg slope, y-intercept of 0)

-x + y = -8  ⇒  y = x - 8  (pos slope, y-interecept at -8)
