1.

So on the first question, it does appear that these triangles are similar by SSS. However, we need to do ratios to prove that. Remember that similar figures have proportional sides, and if these triangles are similar, they will all have the same ratio.

\frac{40}{96} =\frac{96-57}{96} =\frac{44}{64+44} \\ \\ \frac{40}{96}=\frac{39}{96} =\frac{44}{108}

If you divide these fractions, you will see that they are all different ratios, therefore the correct answer is A. not similar.

2.

So firstly, we should convert these fractions into improper fractions and have them under fourths to make this look easier.

To convert a mixed fraction to a improper fraction, multiply the whole number by the denominator and add what's on the numerator for that to be your numerator. The results we get are 7/2 and 21/4.

Next, to make the denominator 4, multiply the denominator and the numerator of 7/2 by 2/2 to get 14/4.

Now the scale says that every 1/4" = 1'. Just count the numerators of both fractions and we see that the answer is going to be A. 14 ft by 21 ft

3.

Now for this, just see how many units it gets from 3 to 1 and from -4 to 0.

We see that it takes -2 units from 3 to 1, and since they are both x-coordinates, the first half of the image is x - 2 .

Next, it takes 4 units to get from -4 to 0. Since they are both y-coordinates, the second half of the image is y + 4.

Putting it together, your image is (x - 2, y + 4), or B.

a cold wave hit chicago when the temperature hit 62 f during the cold wave the temperature dropped 2 degrees every hour how many
Vladimir [108]
We start at 62 Fahrenheit. And every hour we drop two degrees. We want to know how long it took for the temperature to drop to 40 Fahrenheit.

If one hour passed, then the temperature dropped two degrees.
If two hours passed, then the temperature dropped 4 degrees.

See the pattern? We can define this as 2h. Where h represents time in hours.
We subtract 2h from 62. 

We can write this as a function. F(h) = 62 - 2h.
Where F is the temperature in Fahrenheit. And h is the hour(s).

Now that we have the formula, let's plug in the value 40 Fahrenheit to see how long it took for the temperature to drop to 40 degrees.

40 = 62 - 2h
Subtract 62 from each side

-22 = -2h
Divide both sides by 2

h = 11

So, it took 11 hours for the temperature to drop to 40 Fahrenheit.

Find Distance (4,6) (-4,-3)​
vampirchik [111]

Answer:

\sqrt{145}

Step-by-step explanation:

The distance formula states that the distance between two points (a,b) and (c,d) is \sqrt{(a-c)^2+(b-d)^2}.

The two points we have are (4,6) and (-4,-3). Plugging these numbers into the distance formula, we have

\sqrt{(4-(-4))^2+(6-(-3))^2.

Simplifying with order of operations, first using the distributive property, gives

\sqrt{(4+4)^2+(6+3)^2.

Squaring and adding gives

\sqrt{(4+4)^2+(6+3)^2}=\sqrt{8^2+9^2}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\sqrt{64+81}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\boxed{\sqrt{145}},

which is the answer in simplest form. This also rounds to about 12.04.
