Answer:
2.8 hours
Step-by-step explanation:
36.68 / 13.1 = 2.8
(a) The dimensions of the base of the box are (8 -2x) and (10 -2x). The depth of the box is x. The volume is the product of these dimensions.
V = x(8 -2x)(10 -2x)
(b) A graphing calculator is suitable "technology". The process is ...
• write the equation in the calculator
• adjust the scaling so the curve fills the display area
• select the maximum point to reveal its coordinates
The value of x that maximizes box volume is about 1.5 inches.
Answer:
A)x=22
Step-by-step explanation:
when you substitute in 22 both sides of the equation equal 124
6/8 would be simplified by to so, 6/8 = 3/4
Answer:
Step-by-step explanation:
Let x represent the cost of the video game before tax.
A customer buys a CD for $15 and a video game. The expression for the total cost of both items before tax is
15 + x
The customer pays a total of $42.80 for the two items. This includes 7% sales tax. The amount of tax paid by the customer for both items would be
7/100 × 42.8 = $2.996
The amount paid for the items before tax would be
42.8 - 2.996 = 39.804
Therefore, the equation that can be used to find x, the cost of the video game before tax is
15 + x = 39.804
