Two triangles are similar. The sides of the first triangle are 8,10 and 12. The smallest side of the second triangle is 24. Find the perimeter of the second triangle.

Answers

The perimeter of the second triangle is 90 units.

What are similar figures?

Similar figure are zoomed in or zoomed out (or just no zoom) version of each other. They are scaled version of each other, and by scale, we mean that each of their dimension(like height, width etc linear quantities) are constant multiple of their similar figure.

So, if a side of a figure is of length L units, and that of its similar figure is of M units, then:

$L = k * M$

where 'k' will be called as scale factor.

The linear things grow linearly like length, height etc.

For this case, the two considered triangles are similar. Thus:

A side of first triangle = k times corresponding side of its similartriangle

where k is the scale factor, constant for one pair of similar triangles.

We're given that:

Sides of first triangle are of 8,10 and 12 unit length.

Smallest side of second triangle is of 24 units.

Now, smallest side of first triangle will correspond to the smallest side of its similar triangle.

For first triangle, the smallest side is of 8 units (8 is smaller than 10 and 12, the other two sides).

Let the sides of second triangle be of S = 24 units, M units, and L units.

where M is middle sized side and L is largest side of second triangle.

Let the scale factor be 'k'.

Then, we get:

Smallest side of first triangle = k × smallest side of its similar triangle

$8 = k * 24\n\nk = (8)/(24) = (1)/(3)$

Similarly, middle sized side of first triangle = (1/3) × middle sized side of second triangle

$10 = k * M = (1)/(3) * M\n\nM = 3 * 10 = 30$ units.

Thus, the length of middle sized side of second triangle is 30 units.

Largest side of first triangle = (1/3) × Largest side of second triangle

$12 = k * L = (1)/(3) * L\n\nL = 3 * 12 = 36$ units.

Thus, the length of middle sized side of second triangle is 30 units.

Perimeter of the second triangle = sum of length of its sides

= S + L + M = 24 + 30 + 36 = 90 units.

Thus, the perimeter of the second triangle is 90 units.

so 8*3=24, so multiply all of the sides by 3,
the other 2 are 30 and 36

Donovan bought 5 1/2 kilograms of flour for $8.25 how much is the unit rate per kilogram of flour?

Answers

The unit rate is given by the total amount, divided by the number of units. In this case, the amount is 8.25 dollars, and the units are 5.5 kilograms.

So, the unit cost is given by

$(8.25)/(5.5) = 1.5$

Harry and Terry are each told to calculate 8−(2 5). Harry gets the correct answer. Terry ignores the parentheses and calculates 8−2 5. If Harry's answer is H and Terry's answer is T, what is H−T?GIVE U MANY POINTS!!!!!!!!!!

Answers

I'm pretty sure the space is a "+".

so the question was 8-(2+5) which is eual to (first the bracket) 8-7, which is 1

H=1

if you ignore the bracket you have 8-2+5, which is (first the left side) 6+5, which is 11

T=11

and H-T=1-11=-10!
