<h3>The weight of small package is 5 ounces</h3>
<u><em>Solution:</em></u>
The price of mailing a small package is $0.32 for the first ounce
$0.21 for an additional ounce
Let "x" be the additional ounces
From given,
Simone paid $1.16 to mail her package
First ounce = $ 0.32
Therefore,
Money paid for additional ounces = 1.16 - 0.32 = $ 0.84
Given that,
$0.21 for an additional ounce
Therefore,
Thus weight of package = first ounce + 4 additional ounces = 5 ounces
Thus the weight of small package is 5 ounces
Answer:
the equation is in form
y=mx+b where
m=slope
and
b=y-int (the y value for the vertex)
first we look to see what the y value is for the point where x=0 and we can see that it is 5 so b=5
then we look at the slope, slope it the amont of units up then to the side are needed to reach the next point, in this case the line goes up 1 then to the right 1 so the slope is 1/1 (1) so the full equation is
y=x+5
Step-by-step explanation:
Z is directly proportional to x, that means :
z = k.x, with k is the coefficient of proportionality:
Let calculate k:
When x = 5, z = 55. Plug in:
55 = k.5 → k=55/5 ; k =11
The value of z when = 12 is : z= kx; z = 11(12) and z = 132
Answer:
The value of w is:
Step-by-step explanation:
We have to calculate w from the equation
The solution has to be expressed as a logarithm in base 10.
We can solve it like:
The value of w is:
Answer:
b. x^2+4x
Step-by-step explanation:
So since you don't know the width, you can just represent it as a variable, and in this case that variable will be "x". Now using this variable we can use it to represent the length since there is a relationship between the width and length which is given. Since the length is 4 feet greater than the width, we can represent the length as (x+4). Now to find the area, we simply multiply the length * width, which is x * (x+4) = x^2 + 4x
