To figure out how much she spent all we have to do is add up $0.85, $4.50 and $1.50
$0.85 + $4.50 + $1.50 = $6.85
Therefore she spent $6.85
Hope this helps
Let
x-----------> <span>uniform width surrounding the picture
we know that
(10+2x)*(12+2x)=224-----> 120+20x+24x+4x</span>²=224
4x²+44x+120-224=0
4x²+44x-104=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
x=2 in
the answer is2 inches
<h3>Calculate the volume of the sphere</h3>
To start finding the volume of this sphere, we get the following data:
To find the volume we apply the following formula:
, where
- v = volume
- π = pi
- r = radius
We substitute our data in the formula and solve:
Substituting values into the equation
Calculate exponent cubed
Multiplying
Therefore, the volume of the sphere is 32 ft³.
So, 6/7*56/1
56*6/7
336/7
the answer is 48
