Answer:
80%
Step-by-step explanation:
Denise used 360 minutes out of 450 minutes. You would set this up as a fraction. Then, you would have to find out the percentage of how much Denise used. You would put 360/450 across from x/100. You find the value of x by multiplying 360*100 which equals 36000. You then would divide it by 450 to get a product of 80. This is how you would get 80%.
Using a proportional relationship, we have that:
- The table is completed as follows: x = 4, y = 192; x = 6, y = 288; x = 9; y = 432;
- 6 boxes are not enough for 300 pencils, 7 are needed.
<h3>What is a direct proportional relationship?</h3>
A direct proportional relationship is a function in which the output variable is found with the multiplication of the input variable and the constant of proportionality k, as follows:
y = kx.
From the table in this problem, the constant is given as follows:
k = 240/5 = 48/1 = 48.
Hence the relationship is:
y = 48x.
Then:
- When x = 4, y = 48(4) = 192.
- When x = 6, y = 48(6) = 288.
- When x = 9, y = 48(9) = 432.
For 300 pencils, the number of boxes is given by:
48x = 300
x = 300/48
x = 6.25.
There are not decimal parts of a box, a complete box is needed, hence 7 boxes are needed, meaning that 6 boxes are not enough for 300 pencils.

Answer:
Area= 247 feet²
Volume= 1235 feet³
Step-by-step explanation:
A storage pod has a rectangular floor that measures 19 feet by 13 feet and a flat ceiling that is 5 feet above the floor.
Area of the floor= length*width
Length= 19 feet
Width= 13 feet
Area= 19*13
Area= 247 feet²
Volume of the pod= area*height
Height of the pod= 5 feet
Area= 247 feet²
volume= 247*5
Volume= 1235 feet³
If r is the cost of roses which he use 5 d is daisies which he used 3 and f is green filler and he used 4 the cost of 75 more is 234
