Answer:

9) 5y

10) 10 x² - 4

11) 2a ∧5 + 5b

12) 8m +4n + 2

Step-by-step explanation:

9) 8 y - 3 y = 5y

10) 6x² + 4 (x²-1) = 6x²+ 4x²-4 = 10x²-4

11) 4a∧5 - 2a∧5 +4b + b = 2a∧5 +5b

12) 8m +14-12+4n = 8m+4n+2

Marcy is making a hooked circle-shaped rug for her mother. The circumference of the circle-shaped rug is 75.36 inches. What is t
Nesterboy [21]
     The area of the circular shaped rug would be 451.931, let me explain to you how I got this calculation.
     
     First thing you have to do is know the formula to find the area of a circle. The formula is A=pie x Rsquared, but when you look at the information provided, you dont have the radius, so you have to find it yourself. 
 
    You probably noticed that since diameter is twice the radius, the proportion between circumference and diameter is equal to π: <span>C/D = 2πR / 2R = π is the formula for the convertion of circumfrence to diameter.
</span> 
     Once you find the diameter, which should be rounded to 23.98, you will need to divide it by 2 for the radius which should give you approximatly 11.99. 
 
     Finally, you do the regular formula to find area which is A=pie x Rsquared. so you do 3.14 x (11.99 x 11.99)=451.931in.

The area of a square postcard is 25 square inches. How long is each side postcard?​
ivolga24 [154]

Answer:

5 inches

Step-by-step explanation:

To find the area of a square the formula is A = bh which with a square is essentially one side squared. We know this because every side of a square is the same. We also know that 5 squared is 25 meaning the answer is 5 inches(You could also use the formula A = bh : A = 5 x 5 : A = 25).

Digiron [165]

Respuesta: Uno

La suma de la probabilidad de todos los resultados posibles de un experimento aleatorio debe ser igual a uno.

Porque algunos resultados más ocurren en cada sendero y la suma de todas las probabilidades es 100% o uno.

Espero haber ayudado, buena suerte! :)
