Oh yeah guys this has been a very eventful day today.

How to divide things that the divisor is smaller than the dividend? Ex: 9 \ 8

Rzqust [24]

You have to either use decimals or just keep it as a fraction

Which expression is equivalent to 27+15n?

nikitadnepr [17]

3(9+5n)

Use the distributive property to multiply 9 by 3 and 3 by 5n to get that answer.

I suck at math if you could help me with these questions that would be great

docker41 [41]

Answer:

Part 8) The triangles are not similar (see the explanation)

Part 12) The triangles are not similar (see the explanation)

Part 14) The area is increased by 125%

Part 15) $h=30\ ft$

Step-by-step explanation:

Part 8) we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

<em>Find the value of x in the larger triangle</em>

The sum of the interior angles in any triangle must be equal to 180 degrees

so

$64^o+85^o+x=180^o$

$149^o+x=180^o$

$x=180^o-149^o$

$x=31^o$

<em>Find the value of y in the smaller triangle</em>

The sum of the interior angles in any triangle must be equal to 180 degrees

so

$26^o+85^o+y=180^o$

$111^o+y=180^o$

$y=180^o-111^o$

$y=69^o$

so

The corresponding angles of both triangles are not congruent

therefore

The triangles are not similar

Part 12) we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

The measure of the interior angles of the triangle of the left are

88°

29° ----> by vertical angles

and

180°-(88°+29°)=63° ---> the sum of the interior angles in any triangle must be equal to 180 degrees

The measure of the interior angles of the triangle of the right are

180°-91°=89° ----> the sum of a exterior angle and a interior angle is equal to 180 degrees

29°

and

180°-(89°+29°)=62° ---> the sum of the interior angles in any triangle must be equal to 180 degrees

so

The corresponding angles of both triangles are not congruent

therefore

The triangles are not similar

Part 14) we know that

If two figures are similar then the ratio of its areas is equal to the scale factor squared

In this problem the scale factor is 1.5

Because

100%+50%=150%=150/100=1.5

The scale factor squared is $1.5^2=2.25$

That means that the new area is 2.25 times the original area

The area is increased by 125%

Part 15)

Let

h ----> the height of the pine

we know that

The height of the person divided by the length of his shadow is equal to the height of the pine tree divided by the length of its shadow

using proportion

$\frac{6}{3}=\frac{h}{15}$

solve for h

$2=\frac{h}{15}$

$h=2(15)=30\ ft$

Describe two different strategies you could use to add 16 + 35 + 24 + 14.

Vinil7 [7]

Answer:

1. Make a table

2. Combine numbers

Step-by-step explanation:

First what you need to do is make a table making 2 columns, then name them tens and one. Put the tens place in the tens column and put the ones place in the ones column. Then, put all the numbers mentioned (16, 35, 24, 14) in the table and add the tens then add the ones!

Another strategy you can use is combining numbers. With 35 and 16 you can combine them to make 51. Then combine 24 and 14 to make 38. Then you add 51 and 38 to get 89.

I hope this helped your homework!
