Answer:

Scale factor of ΔXYZ to ΔUVW will be 1/5

Step-by-step explanation:

Since all the angles of ΔXYZ and ΔUVW are equal, both the triangles will be similar.

ΔXYZ ~ ΔUVW

Since both the triangles are similar, ratio of the corresponding sides will be in the same ratio.

$\frac{UV}{XY}=\frac{VW}{YZ}=\frac{UW}{XZ}$

And the scale factor = $\frac{\text{Side of UVW}}{\text{Side of XYZ}}$

= $\frac{UV}{XY}$

= $\frac{12}{60}$

= $\frac{1}{5}$

Therefore, scale factor of ΔXYZ to ΔUVW will be 1/5

In the Itty Bitty High School, there are 85 students. There are 27 students who take French, 51 who take Geometry and 38 who tak

andrew-mc [135]

Answer:

58 students

Step-by-step explanation:

Given

$Total = 85$

$French = 27$

$Geometry = 51$

$History = 38$

$None = 5$

$All = 2$

Required

Students that take only 1 subjects

The attached image illustrates the question.

For French only (x), we have:

$x + 7 -2+10-2+2=27$

$x + 15=27$

Collect like terms

$x =- 15+27$

$x =12$

For Geometry only (y), we have:

$y+10-2+15-2+2=51$

$y+23=51$

Collect like terms

$y=-23+51$

$y=28$

For History only (z), we have:

$z +15-2+7-2+2=38$

$z +20=38$

Collect like terms

$z =-20+38$

$z =18$

Students with one subject is then calculated as:

$1\ subject = x+y+z$

$1\ subject = 12 + 28 + 18$

$1\ subject = 58$

I had trouble understanding algebra and now I am in geometry so If you can help me understand both that will be good. I have thi

diamong [38]

Start by completely ignoring the paralelagram.

Let's choose the top triangle as our starter.

To get the top triangle to the position of the bottom triangle, you must translate it.

First, find how many units the first triangle must move down to reach the same level as the bottom triangle, (i'll let you figure it out bu numbering this as a question) 1.<u> </u>

Next, your first triangle should need to move left to reach the position of the second triangle. How many units left does the first triangle need to move?

2.<u> </u>

<u>You moved the first triangle *Blank* units down and *Blank* units left.</u>

Lastly, you need to look at your paralelagram.

Take the same movements you did with the two triangles and transfer them to the nessacary point of the paralelagram.

<em><u>If you need and extra help, or need more explanation, ask in the comments section. I also recomend that you tell me what you got as your answers to one and two so that you can make sure you got the answer correct.</u></em>

Shaun has five coins in his pocket. If he empties the coins onto a table, what is the probability that all five coins will land

Anastasy [175]

Answer:

A. 1/32

Step-by-step explanation:

Ok, the probability for one of the coins to land on heads is 1/2 cause a coin have to sides and chance is 50% that it will land on either of its sides.

If you have 2 coins the probability will be 1/2 for the first coin to land on heads and 1/2 for the second one. The overall probability for 2 coins would be (1/2)*(1/2)=1/4. You could also see it is 1/4 because all of the possible combinations of 2 coins are 4 (HH, HT, TH, TT) and HH is one of four.

It's the same if you have 5 coins. The probability will be (1/2)*(1/2)*(1/2)*(1/2)*(1/2)=1/32 in other words HHHHH is one of 32 possible combinations of 5 coins.
