  • In Mathematics, rectangle and square are both four sided polygon, having all the internal angles equal to 90.The opposite sides of the rectangle are equal in length whereas in square all the sides are same which makes rectangle different from square.

  • Area of rectangle is the product of length and breadth of rectangle. Perimeter of rectangle is twice the sum of its length and breadth. Area of square is side * side and perimeter of square is 4* side.

  • Area of rectangle = l*b

Perimeter of rectangle = 2(l+b)

  • Area of square = side * side

Perimeter of square  = 4 * side

We are given that perimeter of square and rectangle is same and the side of square is 4x-1 and length of rectangle is 2x+2 and width of rectangle is 2x.

Perimeter of Square = Perimeter of rectangle

4 * (4x-1) = 2(4x+2)

16x -4 = 8x + 4

8x = 8

x = 1

The value of x is 1

Side of square = 4 – 1 = 3

Length of rectangle = 4

Breadth of rectangle = 2

Answer:

The number of times he visited the gym is 19 times.

Step-by-step explanation:

A health club down the street has an initial joining fee of $100, and then you pay $5 each time you visit the gym. If Calvin spends $195, how many times did he visit the gym? Define Variable: Equation: Solve (Show all steps):

Let the number of times he visits the gym be represented as x

A health club down the street has an initial joining fee of $100, and then you pay $5 each time you visit the gym. If Calvin spends $195,

The Amount he spends = $195

= $100 + $5 × x

$195 = $100 + 5x

5x = $195 - $100

5x = $95

x = 95/5

x = 19 times

Therefore, the number of times he visited the gym is 19 times.

Answer: 26

Step-by-step explanation:

Okay, so... The new equation would be -2(-3)+20...

So follow the rule of PEMDAS, PEMDAS is;

Parentheses

Exponents

Multiplication

Division

Adding

and Subtracting

Since there are no equations in parentheses and no exponents, we start with multiplication. Which would be -2(-3). ANY parenthesized number beside another number means you must multiply them.

-2(-3) = 6 because a negative multiplied by a negative is a positive..

Now we have 6 + 20 which is 26, so 26 is your answer.

Step-by-step explanation:

The toy rocket will take a time of 6.8571 seconds to hit the ground.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Given that the height of the rocket (h), in meters, in terms of time (t), in seconds, is defined by a quadratic equation.

To determine the time needed for the rocket to hit the ground, that is, a time t greater than zero such that the height is zero. Now we proceed to solve the polynomial:

- 4.9 · t² + 33.6 · t + 4.9= 0

- 4.9 · (t² - 6.8571 · t - 1) = 0

- 4.9 · (t - 6.8571 ) · (t + 6.8571 ) = 0

Hence, the toy rocket will take a time of 6.8571 seconds to hit the ground.

We can write the statement that f is a function from X to Y using the function notation f:X→Y.

Answer:

8 + 2w

Step-by-step explanation:

⇒ Change all signs to addition (subtraction is the same as adding a negative):

5 + 3w + 3 + -w

⇒ Since the expression is now all addition, you can rearrange them in any order. So group the terms together by their type:

5 + 3 + 3w + -w

⇒ Simplify:

8 + 2w

Step-by-step explanation:

Angle (x+1) is equal to 92 degrees, and x equals 91. If x equals 91, then (x+1) equals 92. (x+1) and angle y are equal angles, so therefore, you can determine that angle y is equal to 92 degrees.

Step-by-step explanation:

multiply 6 by 2/3

Answer:

Because AC = BC

=> ️ACB is a isosceles triangle at C

=> m<A = m<B = 71°

At triangle ABC

m<A + m<B + m<ACB = 180°

=> 71° + 71° + m<ACB = 180°

=> m<ACB = 38°

We have m<ACB and m<ECD are 2 opposite angle

=> m<ECD = m<ACB = 38°

At triangle ECD

m<ECD + m<E + m<D = 180°

=> 38° + 90° + m<D = 180°

=> m<D = 52°

Answer:

  22/44

Step-by-step explanation:

The probability of black is the ratio of black cards to all cards. If the Ace and 2 are removed from each suit, there will be 11 of the 13 cards remaining. 2 suits are black, for a total of 2×11 = 22 black cards. Of course there are 4 suits altogether, for a total of 4×11 = 44 total cards. Then you have ...

  P(black) = (black cards)/(total cards)

  P(black) = 22/44

_____

You are expected to be familiar with the fact that a deck of 52 playing cards consists of 4 suits: diamonds, clubs, hearts, spades. Each suit has 13 cards, identified as Ace, 2, 3, ..., 10, Jack, Queen, King. The clubs and spades are black; the diamonds and hearts are red.

Answer from abid58b

Answer:

280 ml as a percentage of 140 l is 0.2%

Step-by-step explanation:

∵ There is an amount of 280 ml

∵ The total amount is 140 l

→ Change the liter to milliliters using the 1st point above

∴ 140 l = 140 × 1000 = 140000 ml

∴ 140 l = 140,000 ml

→ Now divide the amount by the total, then multiply the quotient by 100%

∵ 280 ÷ 140,000 = [tex]\frac{1}{500}[/tex]

∵ [tex]\frac{1}{500}[/tex] × 100% = 0.2%

∴ 280 ml as a percentage of 140 l is 0.2%

Answer:

We conclude that when we put x = 11, it does not satisfy the inequality.

Hence, option (A) is correct.

Step-by-step explanation:

Given the inequality

x - 7 > 12

Any value which makes the inequality FALSE would be the value that not satisfy the inequality.

Putting x = 11 in the inequality

x - 7 > 12

11 - 7 > 12

4 > 12

FALSE!

Reason: 4 can not be greater than 12

Putting x = 33 in the inequality

x - 7 > 12

33 - 7  > 12

26 > 12

TRUE!

Reason: 26 is indeed greater than 12

Putting x = 22 in the inequality

x - 7 > 12

22 - 7 > 12

15 > 12

TRUE!

Reason: 15 is indeed greater than 12

Putting x = 44 in the inequality

x - 7 > 12

44 - 7 > 12

37 > 12

TRUE!

Reason: 37 is indeed greater than 12

Therefore, we conclude that when we put x = 11, it does not satisfy the inequality.

Hence, option (A) is correct.
