Answer:
An obtuse triangle has 1 obtuse angle and 2 acute angles.
Answer:
1. d<1 d less than 1
2.q<3 (q less than 3)
3.c>5 (c greater than)
4.d<d+3 (d less than d plus 3)
5.c<d+3 (c less than d plus 3)
6.q<q+2 (q less than q plus q)
Step-by-step explanation:
Answer:
Length = 7cm, Width = 15cm
Step-by-step explanation:
Length = p
Width = 3(p-2)
= 3p-6
Perimeter = length + width + length + width
= p + 3p-6 + p + 3p-6
= 8p-12
8p - 12 = 44
Isolate 8p.
8p = 44+12
= 56
Find p.
p = 56 ÷ 8
p = 7
Length = 7cm
Width = 3(7)-6
= 21-6
= 15cm
We are given the expanded form and we need to write the standard form:
10 + 8x(1/10) + 3 x(1/100) + 9 x (1/1000)
So, that is:
10 + 0.8 + 0.03 + 0.009
= 10.839
<em>At the end of month 11 she will have $911.</em>

Explanation:</h2>
Recall you need to write complete question in order to get exact answers. In this exercise, I'll assume that the complete question is:
<em>Makayla started a saving account. She starts the account with $20 and adds $80 at the end of each month. She will not remove any money from the account. How much money will she have at the end of month 11?</em>
<em />
So, she starts the account with $20, that is, this is a fixed amount of money and at the end of each month she adds 80$. So:
Let:
m: Represents the months.
s: Represents the amount of money that is saved.
We can write an equation:
![s=20+80m](https://tex.z-dn.net/?f=s%3D20%2B80m)
So, at the beginning of the process
so she have:
![s=20+80(0) \\ \\ s=20](https://tex.z-dn.net/?f=s%3D20%2B80%280%29%20%5C%5C%20%5C%5C%20s%3D20)
But at the end of month 11 she will have:
![s=20+80(11) \\ \\ s=20+80(11) \\ \\ \boxed{s=911}](https://tex.z-dn.net/?f=s%3D20%2B80%2811%29%20%5C%5C%20%5C%5C%20s%3D20%2B80%2811%29%20%5C%5C%20%5C%5C%20%5Cboxed%7Bs%3D911%7D)
So <em>at the end of month 11 she will have $911.</em>
