Answer:

The triangle is obtuse.

It is an isosceles triangle.

The angles add up to 180°.

Step-by-step explanation:

Obtuse triangles are defined as triangles with one angle obtuse angle over 90°. This triangle has an angle of 100°, so it is an obtuse triangle!

Isosceles triangles have 2 equal sides. The two orange dashes on the left and right legs of the triangle tell us they are equivalent, so this is an isosceles triangle as well!

Finally, <em>all </em>triangles add up to 180°! We can prove this by adding the angles.

40° + 40° = 80°

100° + 80° = 180°

investment historically have doubled every 9 years if you start with $2000 investment how much money would you have after 45 yea
Oksi-84 [34.3K]
First you would divide 45 by 9 to see how many times it will double which gives you 5. Then, you would multiply 2000 by 2^5 (or just 2000x2x2x2x2x2) to get $64000

Mrs. Santiago is buying bagels for her office.Each box contains 6 plain, 4 blueberry, and2 onion bagels. Write and interpret a r
yawa3891 [41]

Explanation:

Each box contains

\begin{gathered} 6plain \\ 4blueberry \\ 2onionbagels \end{gathered}

The ratio that compares the number of blueberry bagels in one box to the number of onion bagels in one box will be calculated below as

\begin{gathered} 4:2 \\ in\text{ the simplest form } \\ 2:1 \end{gathered}

This means that for every one onionbagels in the box, there are 2 blueberry bagels

Part B:

Given that there are 20 blueberry bagels, the number if onion bagels will be calculated below as

\begin{gathered} \frac{2}{1}=\frac{20}{x} \\ cross\text{ multiply, we will have} \\ 2x=20 \\ \frac{2x}{2}=\frac{20}{2} \\ x=10 \end{gathered}

Hence,

The final answer is

10\text{ }onion\text{ }bagels
