Answer:

Emily has 5 apples!!!

Step-by-step explanation:

Ok,

Let the apples Emily has be 'x'

Now,

× + 25= 30

Transpose 25 to RHS

× = 30-25

× = 5

Therefore, Emily has 5 apples :D

Hope it helps!!!

When spinning a penny, Claire believes the proportion of times the penny lands on heads is higher than 0.5. She spins a penny 50

ss7ja [257]

It depends on what the level of significance (alpha) is.

Since alpha is not stated, I'll assume that alpha = 0.05 by default.

Because the p-value is smaller than alpha, we reject the null hypothesis.

Therefore, we conclude that the alternative hypothesis is correct and the proportion of heads is greater than 0.5

The graph below represents the relationship between the number of days a book is overdue and the library fine charged. A graph t

Sedbober [7]

The number of days Christen's book is overdue could be 22 according to options given.

The graph which represents the relationship between the number of days a book is overdue and the library fine charged is attached below :

According to the graph, a constant relationship exists between the number of days a book is overdue and the library fine charged when the Number of days book is overdue is about 19 days and above such that the library fine charged stays the same at $10.

Since we are told that Christen's fine for returning the book is the same as the fine she would have paid if book was returned yesterday, then, the number of days Christen's book is overdue could be 20 days and above.

The only value above 20 from the options given is 22.

Hence, 22 is the valid answer.

Quadrilateral ABCD is dilated by a scale factor of 2 centered around (2, 2). Which statement is true about the dilation?

arsen [322]

Answer:

Option (B) is true i.e segment B'D' will run through (2,2) and will be longer than the segment BD.

Step-by-step explanation:

As the assumption quadrilateral ABCD is shown in figure a.

First located the center of the dilation which is located at (2,2) as shown in figure b.

The next thing we want to do is to determine the distance of the center of dilation to each of the points of quadrilateral ABCD as shown in figure b.

Let’s just start with the distance from the center to the point A, but notice we don’t have to move up and down in y direction. So, what we have to do is to increase this by the factor 2. Because this horizontal distance is 1 i.e. the distance from dilation center (2,2) to point A, we just have to multiply by 2 which would be a distance of 2 and this point right here will be the new location of point A’ (0,2).

And the distance from the center to the point C is the horizontal distance of 2 i.e. the distance from dilation center (2,2) to point C, we just have to multiply by 2 which would be a distance of 4 and this point right here will be the new location of point C’ (6,2).

And the distance from the center to the point B is the upward vertical distance of 1 i.e. the distance from dilation center (2,2) to point B, we just have to multiply by 2 which would be a vertical distance of 2 and this point right here will be the location of point B’ (2,4).

And similarly the distance from the center to the point D is the downward vertical distance of 1 i.e. the distance from dilation center (2,2) to point D, we just have to multiply by 2 which would be a vertical distance of 2 and this point right here will be the location of point D’ (2,0).

So, Quadrilateral A'B'C'D' is dilated by a scale factor of 2 centered around (2, 2).

Just notice in figure b that the segment B'D' will run through (2,2) and will be longer than the segment BD.

So,option (B) is true i.e segment B'D' will run through (2,2) and will be longer than the segment BD.

What is 12+24=2(6+ )

Lyrx [107]

Answer:

$\huge \boxed{x=12}$

Step-by-step explanation:

Let the unknown number be x.

12+24=2(6+x)

Switch sides.

2(6+x)=12+24

Expand brackets.

12+2x=12+24

Subtract 12 from both sides of the equation.

12+2x-12=12+24-12

2x=24

Divide both sides of the equation by 2.

(2x)/2=24/2

x=12
