Answer:
80
Step-by-step explanation:
Let the number of dogs be x.
x(75%)=60
x=60/0.75
x=80
Answer:
The answer to your question is: 6x² + 8x.
An isosceles triangle have two equal sides and two equal angles.
<em>The measure of angles in </em>
<em> are: 20, 20 and 140 degrees</em>
Given that:
![PQ = PR = 45mm](https://tex.z-dn.net/?f=PQ%20%3D%20PR%20%3D%2045mm)
![\angle PQR = 20^o](https://tex.z-dn.net/?f=%5Cangle%20PQR%20%3D%2020%5Eo)
I've added as an attachment, triangle ![\triangle PQR](https://tex.z-dn.net/?f=%5Ctriangle%20PQR)
From the attached triangle, we have:
--- base angles of isosceles triangle
So, we have:
--- angles in a triangle
This gives:
![20^o + 20^o +\angle RPQ = 180^o](https://tex.z-dn.net/?f=20%5Eo%20%2B%2020%5Eo%20%2B%5Cangle%20RPQ%20%20%20%3D%20180%5Eo)
![40^o +\angle RPQ = 180^o](https://tex.z-dn.net/?f=40%5Eo%20%2B%5Cangle%20RPQ%20%20%20%3D%20180%5Eo)
Collect like terms
![\angle RPQ = 180^o - 40^o](https://tex.z-dn.net/?f=%5Cangle%20RPQ%20%20%20%3D%20180%5Eo%20-%2040%5Eo)
![\angle RPQ = 140^o](https://tex.z-dn.net/?f=%5Cangle%20RPQ%20%20%20%3D%20140%5Eo)
Hence, the angles of
are:
![\angle RPQ = 140^o](https://tex.z-dn.net/?f=%5Cangle%20RPQ%20%20%20%3D%20140%5Eo)
![\angle PQR = 20^o](https://tex.z-dn.net/?f=%5Cangle%20PQR%20%3D%20%2020%5Eo)
![\angle QRP = 20^o](https://tex.z-dn.net/?f=%5Cangle%20QRP%20%20%3D%2020%5Eo)

Answer:
Nico invest
at 7% and
at 3%
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
<em>At 7%</em>
substitute in the formula above
<em>At 3%</em>
substitute in the formula above
The total interest is equal to
I=I1+I2
I=$174
substitute
![174=0.07x+0.03x-36](https://tex.z-dn.net/?f=174%3D0.07x%2B0.03x-36)
![0.10x=174+36](https://tex.z-dn.net/?f=0.10x%3D174%2B36)
![0.10x=210](https://tex.z-dn.net/?f=0.10x%3D210)
![x=\$2,100](https://tex.z-dn.net/?f=x%3D%5C%242%2C100)
![x-1,200=2,100-1,200=\$900](https://tex.z-dn.net/?f=x-1%2C200%3D2%2C100-1%2C200%3D%5C%24900)
therefore
Nico invest
at 7% and
at 3%
