It would be dilation because the size of the triangle has changed.

Answer:

Option A is correct.

Dilation transformation maps the large triangle onto the small triangle.

Step-by-step explanation:

Dilation states that it is a transformation that changes the size of a figure. It can also become larger or smaller, but the shape of the figure does not change.

Reflection states that an object is the flip of that object over a line, called the line of reflection.

Rotational transformation states that where you turn a figure about a given point. The point regarding which the object is rotated can be inside the figure or anywhere outside it. so, there must be no change in shape or size of the object.

Translation states that it used in geometry to describe a function that moves an object a certain distance.The object is not altered in any other way. It is not rotated, reflected or re-sized.

All these three i.e Reflection , Rotational and Translation transformations are rigid preserve the figure sizes.

Therefore, you can see in the figure the dilation transformation maps the large triangle onto the small triangle.

Compare the theoretical probability to the experimental probability of landing on H.

cestrela7 [59]

The correct statement comparing the theoretical and experimental probabilities is given as follows:

$\frac{1}{4} < \frac{7}{25}$ .

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

The theoretical probability is taken before any experiment. Since the four sections are equal, the theoretical probability is:

T(H) = 1/4.

The experimental probability is taken considering previous experiments. Out of 100 tosses, 28 landed on H, hence:

E(H) = 28/100 = 7/25.

Hence the correct statement is:

$\frac{1}{4} < \frac{7}{25}$ .

Jenny can swim 10 laps In 5 minutes. How many laps should she swim in 1/3 of an hour?

DIA [1.3K]

1/3 of an hour is 20 minutes. If show 10 laps in 5 minutes, just divide 20 by 5, which gives you 4, then multiply 4 times 10. She can swim 40 laps in 1/3 of an hour. Hope that helps. Mark Brainliest if it does. Thank you!

These two boxes have the same volume

Ronch [10]

Since volume is L*W*H and both are equal then you can have

2*3*6=3*4*x

You can reduce it down to

36=12x

Divide each side by 12 and you have

x=3
The length is 3 in

A store sells gift cards in preset amounts.You can purchase gift cards for $10 or $25. You have spent $285 on gift cards. Erie a

pav-90 [236]

Answer:

10x + 25y = 285

One $25 gift cards with 26, $10 gift cards.

Three $25 gift cards with 21, $10 gift cards and

Five $25 gift cards with 16, $10 gift cards.

Step-by-step explanation:

I can purchase gift cards for $10 or $25. I have spent $285 on gift cards.

If I have purchased x number of $10 gift cards and y number of $25 gift cards then the equation that models the situation in standard form will be given by

10x + 25y = 285 .......... (1)

Now, for y = 1, x = 26

For, y = 3, x = 21

For, y = 5, x = 16

So, here are the three combinations of gift cards that I could have purchased.

One $25 gift card with 26, $10 gift cards.

Three $25 gift cards with 21, $10 gift cards and

Five $25 gift cards with 16, $10 gift cards. (Answer)
