The length and width of each rectangle is given. Which rectangle will not have the same perimeter as the others? l = 12, w = 12

Virty [35]

Rectangle 2 (l = 14, w = 9) will not have same perimeter as the others

Solution:

Given length and width of the 4 rectangles.

Rectangle 1: length = 12 units, width = 12 units

Perimeter of the rectangle = 2(length + breadth)

Perimeter of rectangle 1 = 2(12 + 12)

= 2 × 24

= 48 units

Perimeter of rectangle 1 = 48 units

Rectangle 2: length = 14 units, width = 9 units

Perimeter of rectangle 2 = 2(14 + 9)

= 2 × 23

= 46 units

Perimeter of rectangle 2 = 46 units

Rectangle 3: length = 8 units, width = 16 units

Perimeter of rectangle 3 = 2(8 + 16)

= 2 × 24

= 48 units

Perimeter of rectangle 3 = 48 units

Rectangle 4: length = 13 units, width = 11 units

Perimeter of rectangle 4 = 2(13 + 11)

= 2 × 24

= 48 units

Perimeter of rectangle 4 = 48 units

Hence rectangle 2 (l = 14, w = 9) will not have same perimeter as the others.

The probability of randomly drawing a red card from a bag that contains red, blue, and green cards is 3/10. What is the probabil

Katarina [22]

If the probability of drawing a red card is 3/10, then if we take this fom a whole, 10/10, we can find the probability of not choosing a red card.
10/10-3/10=7/10

The probability of not drawing a red card is 7/10 or 70%.

[Right Triangles Only] cosθ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Define

Identify variables

Angle θ = 45°

Adjacent Leg = 25

Hypotenuse = x

Step 2: Solve for x

Substitute in variables [cosine]: $\displaystyle cos(45^\circ) = \frac{x}{25}$
[Multiplication Property of Equality] Multiply 25 on both sides: $\displaystyle 25cos(45^\circ) = x$
Rewrite: $\displaystyle x = 25cos(45^\circ)$
Evaluate: $\displaystyle x = \frac{25\sqrt{2}}{2}$

Lorenzo's family is driving to the beach to go kayaking with sea otters. The beach is 85 miles from Lorenzo's house. They have a

Cerrena [4.2K]

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but I'm guessing that you want to find the equation to know the miles left for Lorenzo family to reach the beach.

The equation will be gotten by subtracting the distance that the family has driven already from the total distance from their house to the beach. This will be:

= 85 miles - 63 miles

= 22 miles
