We know that

<span>1½ cup of cleaner-------> (1*2+1)/2-----> 3/2 cup of cleaner

</span><span>the ratio of cleaner to water=(3/2)/12---> 3/(2*12)--> 3/24-->  1/8

A pet store sells mice reptiles and birds Let event A = a customer buys a mouse Let event B = A customer buys a reptile What doe
enyata [817]

Answer:

The correct option is C.

Step-by-step explanation:

According to the question given in the attached picture:

Event A = a customer buys a mouse

Event B = A customer buys a bird

P(A or B) = 0.25

Now have a look at the probability P(A or B). Here or means either..Its means that the customer will purchase either a mouse or a bird. That means that there is 0.25 or 25% probability that the customer will purchase either a mouse or a bird. In this case there are only 3 choices, which are: the customer will either purchase a mouse, a bird or a reptile because the pet store has only these three possible outcomes. We are not told that how much of each animal they have. Thus the probability that the customer will either purchase either a mouse or a bird is  0.25 or 25%. That means that the probability of either purchasing a mouse or a bird is added together which is 0.25 or 25%

Thus the correct option is C....

1 hour and 59 mins = 119 mins

119+18 = 137

137/60 = 2 r 17

(10 - 2 = 8) - 17/60

PLS help me fast!!!!
Radda [10]

Answer:

The correct option is 1.

Step-by-step explanation:

It is given that the box plot shows the number of books sold each day at a store for 80 days.

A box plot is drawn with end points at 0 and 16.  It means minimum value is 0 and maximum is 16.

The box extends from 2 to 12. It means first quartile is 2 and the third quartile is 12. A vertical line is drawn inside the box at 7, it means median is 7.

He have to find the number of days in which the bookstore sell 2 to 12 books.

2 is first quartile and 12 is third quartile, we know that

Q_1=25\%

Q_3=75\%

Q_3-Q_1=75\%-25\%=50\%

The data lies between Q₁ and Q₃ is 50% of the data.

80\times \frac{50}{100}=40

The bookstore sell 2 to 12 books in 40 days.

Therefore, the correct option is 1.

Match the system of equations on the left with the number of solutions on the right
erastova [34]

Answer:

top to bottom, the answers are b, c, a

Step-by-step explanation:

One way to find the solution to a system of equations is to substitute values in. For the first one,

y=2x+3

y=2x+5,

we can substitute 2x+3 =y into the second equation to get

y=2x+5

2x+3 = 2x+5

subtract 2x from both sides

3 = 5

As 3 is not equal to 5, this is never equal and therefore has no solution

For the second one,

y= 2x+7

y = (-2/3)x + 10

We can plug y=2x+7 into the second equation to get

2x + 7 = y = (-2/3)x + 10

2x + 7 = (-2/3)x + 10

add (2/3)x to both sides to make all x values on one side

2x + (2/3)x + 7  = 10

subtract 7 from both sides to make only x values on one side and only constants on the other

2x + (2/3)x = 3

(6/3)x + (2/3)x = 3

(8/3)x = 3

multiply both sides by 3 to remove a denominator

8x = 9

divide both sides by 8 to isolate x

x=9/8

There is only one value for when the equations are equal, so this has one solution

For the third one

y = x-5

2y = 2x - 10

Plug x-5 = y into the second equation

2 * y= 2*(x-5)

2 * (x-5) = 2x - 10

2x-10 = 2x-10

add 10 to both sides

2x=2x

As 2x is always equal to 2x, no matter what x is, there are infinitely many solutions for this system
