80% of all households have a rice cooker. 35% of all households have a rice cookers and an instant pot. What is the probability that a household has an instant pot given that it has a rice cooker?

Answers

Answer:

A rice cooker, also known as a rice steamer, is a popular small appliance that works like a slow cooker by using moist heat to cook food while trapping the flavors in the pot until it’s ready to enjoy. Modern rice pressure cookers significantly reduce rice-making time and often feature a warming setting so you can be flexible with meal times.

1 and 1/5y+3/10y-1/2y=1/3y+2/5

Answers

1/5y + 3/10y - 1/2y - 1/3y = 2/5
6/30y + 9/30y - 15/30y - 10/30y = 2/5
-10/30y = 2/5
y = 2/5 x (-30/10)
y = -6/5

Answer: y=12/20=0.6

Step-by-step explanation:

Rephrase the given equation

1 and 1/5y+3/10y-1/2y=1/3y+2/5

6/5y+3/10y-1/2y=1/3y+2/5

Find the GCF (greatest common factor) and multiply it on both sides

(6/5y+3/10y-1/2y)×30=(1/3y+2/5)×30

36y+9y-15y=10y+12

Add like terms together

30y=10y+12

Subtract 10y on both sides

30y-10y=10y+12-10y

20y=12

Divide 20 on both sides

20y/20=12/20

y=12/20=0.6

The first equation in a system is 5x+2y=-4. Which equation gives a system with no solution.

Answers

Answer:

= 0.8 + -0.4y

Step-by-step explanation:

Simplifying

5x + 2y = 4

Solving

5x + 2y = 4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

5x + 2y + -2y = 4 + -2y

Combine like terms: 2y + -2y = 0

5x + 0 = 4 + -2y

5x = 4 + -2y

Divide each side by '5'.

x = 0.8 + -0.4y

factorise 49m²-84mn+36n² using the identity x²+(a+b)x+ab=(x+a)(x+b)​

Answers

Answer:

(7m-6n)(7m-6n)

Step-by-step explanation:

Given the expression 49m²-84mn+36n², this can also be written as;

49m²-84mn+36n²

= 7²m² - 84mn + 6²n²

= (7m)²-2*7m*6n+ (6n)²

= (7m-6n)²

= (7m-6n)(7m-6n)

Hence the expanded form is  (7m-6n)(7m-6n)
