An unknown metal having a mass of 287.8 g was added to a graduated cylinder that contained
31.47 mL of water. After the addition of the metal, the water level rose to 58.85 mL. Determine
the volume of the metal. Calculate the density of the metal using dimensional analysis.
The metal displaced a volume of
58.85 mL - 31.47 mL = 27.38 mL = 27.38 cm³
of water, which is to say the metal has this volume.
If the metal has a mass of 287.8 g, then its density is its mass per unit volume,
(287.8 g)/(27.38 cm³) ≈ 10.51 g/cm³
We can calculate the volume V of a rectangular prism using V = lwh, where l is the length, w is the width, and h is the height of the
prism. Suppose that a prism has a volume of 200 cm and l = 2w.
a. Select all of the equations that rewrite the volume formula by making substitutions for V and l.
200 = 2w²h
200 = 4wh
V = 22
2w xwxh = 200
Answer:
Step-by-step explanation:
200=2w²h
The equations are -
200 = 2[tex]w^{2}[/tex]h
2w x w x h = 200
We have a prism and the formula to calculate its volume is given.
We have to select all of the equations that rewrite the volume formula by making substitutions for V = 200 cubic centimeter and L = 2w.
What is Prism ?A Prism is a three-dimensional shape, which consists of two identical polygons, which do not lie in the same axis.
According to the question, we have -
Volume of Prism = 200 cubic centimeter
L = 2w
The formula to calculate the volume of prism equals to -
V = Lwh
Substituting values, we get -
200 = 2[tex]w^{2}[/tex]h
or
2w x w x h = 200
Hence, the equations are -
200 = 2[tex]w^{2}[/tex]h
2w x w x h = 200

The cost price of a box and a pen is Rs 80 The box is sold at 10% profit and the pen is sold at 20% loss. If the selling price of the box is Rs 28 more than that of the pen, calculate the profit or loss percent in a whole.
Answer:
61.84%
Step-by-step explanation:
Let the cost of the box be x. Since the price of the box and the pen is Rs 80, the pen's price can be represented as 80 - x. The box is sold at a ten percent profit, and an added ten percent is equal to 1.1. Therefore, the price the box sells at is 1.1(x). A 20% loss is the same a keeping 80% or multiplying by 0.8. This means the pen sold at 0.8(80 - x). Now, we are given the box went for Rs 28 more than the pen, so we can create an equation:
1.1x = 0.8(80 - x) + 28
We can simplify and solve:
1.1x = 64 - 0.8x + 28
1.9x = 92
x = 92/1.9
x = 920/19
The cost of the box after the increase would be 1.1(920/19) and the pen would be 0.8(80 - 920/19).
The sum of these two can be written as a percent x of 80.
80x = 0.8(80 - 920/19) + 1.1(920/19)
80x = 64 - 0.8(920/19) + 1.1(920/9)
80x = 64 - 0.3(920/19)
80x = 64 - 276/19
80x = 940/19
x = 940/1520
x = 0.6184
This is 61.84%

Step-by-step explanation:
The absolute value of a number is its distance from 0. This means a number would be itself if it was positive and if it was negative it would be its opposite. Since 985 is positive, |985| would just be 985.

Since the card has $0 minimum payments for the first 4 years it is active, Emma wonders how much it will cost her if she
doesn't pay off the $300 balance until after college. How much will she owe in 4 years?
Type the correct response in the box. Use numerals instead of words. Round your answer to the nearest dollar.
In 4 years, Emma will owe about $
Answer:
$544.61
Step-by-step explanation:
Edmentum
In 4 years, Emma will owe about $544.61 to the credit card company.
The model for Emma's debt in 4 years is given as:
FV = P(1+r/n)^nt,
where:
P = principal ($300)
r = the interest rate (15%)
t = the time in years (4 years)
n = the number of times the interest is compounded per year (12)
However, we can solve the problem with an online financial calculator as follows:
Data and Calculations:N (# of periods) = 48 (4 x 12 months)
I/Y (Interest per year) = 15%
PV (Present Value) = $300
PMT (Periodic Payment) = $0
P/Y (# of periods per year) = 12
C/Y (# of times interest compound per year) = 12
Results:
FV = $544.61
Total Interest = $244.61
Complete Question:Emma doesn't have experience using credit cards. In fact, she just got her first one. She is also about to start her first year of college. She uses her new credit card to purchase textbooks for her classes. The total comes to $300. These are the terms of her credit card:
It has a 15% annual interest rate.The interest is compounded monthly.The card has $0 minimum payments for the first four years it is active.Thus, in 4 years, Emma will owe $544.61 to the credit card company.

Step-by-step explanation:
If A is the midpoint of Line Segment XY, then we can conclude that the length of XA = the length of AY. ((in other words, XA = AY))
Find XA
Insert equations // 2x = 10x - 8It's best to solve for "x." So we do this by flipping the equation (you can do this in any way you want, but this seemed easier) // 8 = 10x - 2x8 = 8x // Divide for x // x = 1Finding the Length of AY (Calculating Length)
Substitute x = 1 from XA // 10(1) - 8We get an answer of 2 ((this is the length of AY))Finding the Length of XA
Substitute x = 1 from XA // 2(1)We get an answer of 2 ((this is the length of XA)Finding the Length of XY
XA = AY // the length of XA is 2 (or 2 units, or whatever you are measuring in) and the length of AY is 2, then finding the length of XY means adding both lengths togetherXA = AY = 2 = 2 = 2 + 2 = 4 ((the length of XY is 4))Can someone explain this?
