Answer:
1 ft³ of gold will weigh 1209.6 pounds
1 ft³ of copper will weigh 559 pounds.
Step-by-step explanation:
We know the formula for:
Density = Mass/Volume
Hence, making mass the subject of the formula:
Mass = Density × Volume
From the question we are told:Volume of each metal = 1 ft³
1) Metal: Gold
Density of Gold = 0.70 pounds per cubic inch(lb/in³)
We convert the Volume of gold from ft³ to in³
The Volume of gold given in the question = 1 cubic foot = 1 ft³
1 cubic foot = 1728 cubic inches
Hence, the volume of Gold = 1728 in³
Mass of Gold = Density of Gold × Volume of Gold
Mass of Gold = 0.70Ib/in³ × 1728 in³
= 1209.6 lb(pounds)
2) Metal : Copper
Density of copper given in the question = 8.96 grams per cubic centimeter
Ib = pounds
We convert this density in g/cm³ to ib/in³
453.5g = 1 Ib
8.96g = a Ib
Cross Multiply
= 453.5g × a Ib =8.96g × 1 Ib
= a Ib = 8.96g × 1 Ib/453.5g
a Ib = 0.0197574421 Ib
Density of Copper = 0.0197574421 Ib/cm³
28,316.8 cm³ = 1 ft³
1 cm³ = b ft³
b ft³ = 1 cm³ × 1 ft³/28,316.8cm³
b ft³ = 0.0000353147 ft³
1 cm³ = 0.0000353147 ft³
We have to convert the density of Copper from Ib/cm³ to Ib/ft³
0.0197574421 Ib/cm³ = 0.0197574421 Ib/0.0000353147 ft³
559.46793026 Ib/ft³
Volume of copper = 1ft³
Mass = Density × Volume
Mass of copper = 559.46793026 Ib/ft³ × 1 ft³
= 559.46793026 Ib or pounds
≈ 559 pounds
Therefore , the weight of gold is 1209.6 pounds and the weight of copper will be 559 pounds.
Answer:
Gold
Density of Gold = 0.70 pounds per cubic inch
1 cubic foot = 1728 cubic inches
Hence, the volume of Gold = 1728 in³
Mass of Gold = Density of Gold × Volume of Gold
Mass of Gold = 0.70Ib/in³ × 1728 in³ = 1209.6 lb(pounds)
2) Metal : Copper
Density of copper given in the question = 8.96 grams per cubic centimeter
We convert this density in g/cm³ to ib/in³
453.5g × a Ib =8.96g × 1 Ib = 8.96g × 1 Ib/453.5g = 0.0197574421 Ib
Density of Copper = 0.0197574421 Ib/cm³
Volume of copper = 1ft³
Mass = Density × Volume
Mass of copper = 559.46793026 Ib/ft³ × 1 ft³ = 559.46793026 Ib or pounds
≈ 559 pounds
The weight of gold is 1209.6 pounds and the weight of copper will be 559 pounds.
Ameezy has four times as many water bottles
as Beetle does. If the two of them have a
combined total of sixty bottles, how many
more bottles does Ameezy have than Beetle?
Answer:
30
Step-by-step explanation:
15 x 4 = 60, which means that Beetle has 15 bottles of water and that Ameezy has bottles. 45 - 15 = 30.
Hope this helps :)
Answer:
36 bottles.
Step-by-step explanation:
If you wrote them out, like 1 over 4, 2 over 8, and added up their totals at the bottom, you would eventually reach 60. The last column has 12 over 48, so we subtract 12 from 48, which gives us 36. So the answer is 36 bottles.

what is the perimeter of rectangle JKLM
Find lengths by reasoning shortcut
JK=6-1=5unitsJM=6-3=3unitsIts a rectangle
Perimeter:-
2(JK+JM)=2(5+3)=2(8)=16units
Answer:
Perimeter = distance around a two-dimensional shape
⇒ Perimeter of a rectangle = (2 × width) + (2 × length)
From inspection of the diagram:
width = 3 unitslengths = 5 units⇒ Perimeter of the rectangle = (2 × 3) + (2 × 5)

please mark brainliest♡♡
Step-by-step explanation:
First separate the shape into two rectangular
27 - 9= 18
18×10= 180cm²
9×24= 216c m²
Answer:
396 cm²
Step-by-step explanation:
Area = 10 x (27 - 9) + 24 x 9
= 10 x 18 + 24 x 9
= 20 x 9 + 24 x 9
= 44 x 9

Which deal is better? Pizza A is 10-inch diameter for $15 or Pizza B is a 12-inch diameter for $27? Which do you get more pizza per dollar spent?
Answer:
the answer is pizza b
Step-by-step explanation:
first i did 15 divided by 10=1.50
then i did 27 divided by 12=2.25
then i did 1.25%of 12=0.15
then 2.25 of 12=0.27
you get more pizza per dollar with pizza b

What is the value of log Subscript 0. 5 Baseline 16? –4. 00 –0. 25 1. 51 2. 41.
The value of the logarithm expression [tex]log_{0.5}(16)[/tex] evaluated is given by : Option A: -4.00
What is logarithm and some of its useful properties?When you raise a number with an exponent, there comes a result.
Lets say you get
[tex]a^b = c[/tex]
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
[tex]b = log_a(c)[/tex]
Some properties of logarithm are:
[tex]\log_a(b) = \log_a(c) \implies b = c\\\\\log_a(b) + \log_a(c) = \log_a(b \times c)\\\\\log_a(b) - \log_a(c) = \log_a(\frac{b}{c})\\\\\log_a(b^c) = c \times \log_a(b)\\\\\log_b(b) = 1\\\\\log_a(b) + log_b(c) = \log_a(c)\\[/tex]
Log with base e = 2.71828... is written as [tex]\ln(x)[/tex] simply.
Log with base 10 is written as [tex]\log(x)[/tex] simply.
For this case, we have to simplify the expression [tex]log_{0.5}(16)[/tex]
Let this is equal to 'a', then:
[tex]a = \log_{0.5}(16)\\\\0.5^a = 16\\(\dfrac{1}{2})^a = 16\\\\1^a/2^a = 2^4\\\\1 = 2^4 \times 2^a\\2^0 = 2^{4+a}\\\\0 = 4 + a\\a = -4[/tex]
(we used the property that: [tex]b^0 = 1[/tex] and [tex]k^m \times k^n = k^{m+n}[/tex] )
Thus, the value of the logarithm expression [tex]log_{0.5}(16)[/tex] evaluated is given by : Option A: -4.00

Please evaluate this equation, and explain how you got the answer.
Answer:
3 = f
Step-by-step explanation:
3(6 - f) - 4 = 3f - 4
Distribute within Parenthesis
18 - 3f - 4 = 3f - 4
Combine like terms
14 - 3f = 3f - 4
Add 3f on both sides of the equation

Add 4 on both sides of the equation
18 = 6f
Divide by 6 on both sides of the equaiton to get your answer of

The numbers 20 through 30 were written on individual cards and placed in a bag. If you take one card from the bag, what is the probability that it will not have the digit 2 on it?
Answer:
1/10

20 21 22 23 24 25 26 27 28 29 30
X. X. X. X. X. X. X. X. X. X. V
1/10
20-29 all have a 2 in it meaning 30 is the only digit that doesnt have a 2 so 1/10 numbers
If one card taken from the bag then the probability that will not have the digit 2 on it is 1/11.
What is probability ?Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Given that,
Numbers from 20 to 30 are written on individual cards.
The total numbers of cards = 11
And numbers on cards = 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30
To find the probability of cards that have not the digit 2 on it.
Since, there is only one digit 30, which does not have digit 2,
Therefore, probability = favorable outcome / total outcome
= 1 / 11
The required probability of choosing a card that will not have the digit 2 on it is 1/11.

[tex]Z=\dfrac{X-\mu }{\sigma}[/tex]
where,
Z = Z score,
X = raw score,
μ = mean,
σ = standard deviation,
The probability of the students to be selected randomly between 350 and 550 will be given as
[tex]=P(350 < X < 550)[/tex]
[tex]=P(350-500 < X-500 < 550-500)[/tex]

What is the image of (x,y) after a translation of 3 units left and 7 units down?
Answer:
[tex](x + 3, y - 7)[/tex]
Step-by-step explanation:
Given
[tex]Function = (x,y)[/tex]
Translation:
[tex]Left = 3\ units[/tex]
[tex]Down = 7\ units[/tex]
Required
Determine the image of the function
Apply the first translation
[tex]Left = 3\ units[/tex]
When function (x,y) is 3 units translated left, we add the units to the x value.
The new function becomes:
[tex](x,y) -> (x + 3, y)[/tex]
Apply the second translation
[tex]Down = 7\ units[/tex]
We subtract 7 units from the y value
[tex](x,y) -> (x + 3, y)[/tex]
becomes:
[tex](x + 3, y) ->(x + 3, y - 7)[/tex]
Hence:
The image of the function is:
[tex](x + 3, y - 7)[/tex]
