Answer:
40 ounces
Step-by-step explanation:
One foot = 12 inches
3 inches is 1/4 of a foot
Divide 10 pounds by 4 to get 2.5 pounds
Convert to ounces
Answer:
density =8.87g/cm³
From chart the density shows that it is a Colsibro copper alloy, a precipitation hardening copper nickel silicon.
Step-by-step explanation:
This problem bothers on the density of substances
Given data
Mass m of substance = 239.6grams
length l=3cm
width b=3cm
height h=3cm
Volume of substance =l*b*h
=3*3*3=27cm³
We know that the density of the substance ρ=mass/volume
ρ= 239.6/27= 8.87g/cm³
To find the area of a rectangle, we multiply the Base by the Height. In this case the: Base = AB and Height = BC
So to get the area, we multiply AB by BC. (and we know that <em>BC = 5x+5/x+3</em> <em>and BC = [3x+9/2x-4)</em>
So we would do:
x
Note: When multiplying fractions together, we multiply the numerator by the numerator, and the denominator by the denominator.
For example
x
=
Answer:
x
= 
=
[<em>Note: </em><em>we are able to factorise some brackets to make the sum easier. For example we can factor out the 5 in (5x+5) to get: 5(x+1) ]</em>
Now lets simplify by multiplying the 5 and 3 together in the numerator:
= 
If you notice, there is a (x+3) in numerator and the denominator. This means that we can cancel out the (x+3), to get the most simplified expression for the area:
=
