Answer:
42,000 X 6 % = $2520.00
42,000 x 2 = 84,000
84,000 x 6% = $5,040
Step-by-step explanation:
Answer:
Im going to guess that this is a true or false question so..
True :)
Good morning Brainiac
x+y = 13
1/2 x +y = 10
We gonna solve x+y=13 for x
So let's start by adding -y to both sides
x+y -y = 13-y
x= -y +13
Now substitute -y+13 for x in 1/2 x +y=10
1/2 x +y = 10
1/2 (-y+13)+y=10
1/2 y + 13/2 = 10
Now add -13/2 to both sides
1/2 y+13/2 -13/2 = 10- 13/2
1/2 y = 7/2
Now eliminate the common denominator which is 2
y = 7
Now we have the value for y, so lets find the value for x by substitute 7 for y in x= -y+13
x= -y+13
x= -7 + 13
x= 6
Answer : (6,7)
The answer is B
I hope that's help and if you have questions please let me know :)
Good luck
Answer:
New can holds
more than the old can
Step-by-step explanation:
Given: Diameter of the can is 6 cm and height is 12 cm such that volume of can is ![339.12\,\,cm^3](https://tex.z-dn.net/?f=339.12%5C%2C%5C%2Ccm%5E3)
Dimensions of the can are increased by a multiple of 1.10
To find: Difference between the volume of new can and volume of old can
Solution:
Volume of can (v) = ![339.12\,\,cm^3](https://tex.z-dn.net/?f=339.12%5C%2C%5C%2Ccm%5E3)
Let r, h denote radius and height of the can.
Let R, H denotes radius and height of the new can.
r = diameter/2 = ![\frac{6}{2}=3\,\,cm](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B2%7D%3D3%5C%2C%5C%2Ccm)
h = 12 cm
R = ![3(1.1)=3.3.\,\,cm](https://tex.z-dn.net/?f=3%281.1%29%3D3.3.%5C%2C%5C%2Ccm)
H = ![12(1.1)=13.2\,\,cm](https://tex.z-dn.net/?f=12%281.1%29%3D13.2%5C%2C%5C%2Ccm)
New volume (V) = ![\pi (R)^2H=\pi(3.3)^2(13.2)=451.37\,\,cm^3](https://tex.z-dn.net/?f=%5Cpi%20%28R%29%5E2H%3D%5Cpi%283.3%29%5E2%2813.2%29%3D451.37%5C%2C%5C%2Ccm%5E3)
So,
![V-v=451.37-339.12=112.25\,\,cm^3](https://tex.z-dn.net/?f=V-v%3D451.37-339.12%3D112.25%5C%2C%5C%2Ccm%5E3)
The solution of a system of equations is the place where they cross; the point where both equations are true. find the place on your graph where your two lines intersect.
you should find (2, 3) as the intersection point. this is the solution for the system.
