Given that the triangles are similar how to find x

Mathematics

So if they are similar then just try to figure out which two sides correspond to each other from the first and then the second triangle.

See how in the above example I did 20 and 5 not 20 and 14 or 20 and 3.5 because they do not correspond with one another.

Then figure out, is x on the mama or baby shape and either multiply the number received from all proportions or divide.

Multiply : small to big ( # missing on the bigger one )

Divide : big to small ( # missing on the smaller one)

Can someone plz help me no links plz I beg u I’m confused I would really appreciate it

Answer: A

Step-by-step explanation:

The maximum amount of weight the truck can carry is 1600lbs. You do not want to exceed 1600lbs, but you can reach 1600lbs. This makes the inequality symbol ≤. This symbol says that the weight load has to be less than 1600lbs, but It can equal 1600lbs. You know that the piano is 400lbs and each box is 50lbs. Since you want to figure out how many boxes you can put on the truck alongside the piano, you can use the inequality: 50x + 400 ≤ 1600.

50 represents pounds per/box

x represents the number of boxes you can hold

400 represents the weight of the piano

1600 represents the max weight.

Find the lateral area for the pyramid with the equilateral base

likoan [24]

<h3>The lateral area for the pyramid with the equilateral base is 144 square units</h3>

Solution:

The given pyramid has 3 lateral triangular side

The figure is attached below

Base of triangle = 12 unit

Find the perpendicular

By Pythagoras theorem

$hypotenuse^2 = opposite^2 + adjacent^2$

Therefore,

$opposite^2 = 10^2 - 6^2\\\\opposite^2 = 100 - 36\\\\opposite^2 = 64\\\\opposite = 8$

Find the lateral surface area of 1 triangle

$\text{ Area of 1 lateral triangle } = \frac{1}{2} \times opposite \times base$

$\text{ Area of 1 lateral triangle } = \frac{1}{2} \times 8 \times 12\\\\\text{ Area of 1 lateral triangle } = 48$

Thus, lateral surface area of 3 triangle is:

3 x 48 = 144

Thus lateral area for the pyramid with the equilateral base is 144 square units

In a word game, you choose a tile from a bag, replace it, and then choose another. If there are 28 vowels and 12 consonants, wha

ohaa [14]

With replacement:

P(C,V)=(12/40)(28/40)

P(C,V)=336/1600

P(C,V)=21/100

Statistics Practice Q8

The answer is B, at first the sum is 621 and then you divide by 7 to get your median (88), after you add the two #s of 86 and 87 to 621 and divide by 9. Resulting in the median being 88
