what is the result of converting 60 ounces to pounds remember there are 16 ounces in a pound brainly
The 60 ounces equals 3.75 pounds.
We are given in question the relation between pound and ounce. So, using that to find out the result of converting 60 ounces to pound. We will simply divide the given number of ounces by number of ounces in a pound.
Representing the given relation in equation form -
16 ounces = 1 pound
Thus, 1 ounce = [tex]\frac{1}{16}[/tex] pounds
Rewriting the equation for 60 ounces
So, number of pounds in 60 ounces will be = [tex]\frac{1*60}{16}[/tex]

To make 1 batch of vegetable soup, Sam needs 16 ounces of water and 8 ounces of vegetables. How does the amount of water compare to the amount of vegetables?
Answer:
There is two ounces of water for every ounce of vegetables.
Step-by-step explanation:
Given that:
Sam needs 16 ounces of water and 8 ounces of vegetables to make 1 batch of vegetable soup.
Ratio is defined as the quantitative relation between two numbers.
We will use ratio to compare the amount of water to amount of vegetables.
Ratio of water to vegetables
16 : 8
Dividing by 8
[tex]\frac{16}{8}:\frac{8}{8}[/tex]
2:1
Hence,
There is two ounces of water for every ounce of vegetables.
A shop sells cereal in boxes A, B and C. Box A 500 g for $1.73 Box B 750 g for $2.60 Box C 1.25 kg for $4.35. which box is the best value?
Answer:
Box C
Step-by-step explanation:
First switch the box that's in kilograms into grams. One kilogram=1000 grams. So box C is 1250 grams.
Next divide the amount in each box by the cost of each box.
Box A 500/173=2.89
Box B 750/260=2.88
Box C 1250/435=2.87
So, since box C has the lowest amount when divided, that box has the best value.
A bin in the gym holds 40 balls, which are a mix of

120% of x is 96. What is x?
Answer:
Step-by-step explanation:
You can do this using a small equation.
120% x = 96 Change 120% to a decimal
120/100 * x = 96 Multiply by 100
120x = 96 * 100
120x = 9600 Divide by 120
x = 9600/120
x = 80
Look what you got. 20% more than 80 is 96. x is smaller than 96.
If you take 20/100 * 80 = 16
if you add 16 to 80, you get 96
Answer:
x = 80
Step-by-step explanation:
120 % of x = 96
or, 120/ 100 × x = 96 change percentage to 100 and devide
or, 6 / 5 × x = 96
or, 6x / 5 =96. multiply 6 and x
or, 6x = 96 × 5. change devide sign to multiply
or, 6x = 480. multiply
or, x = 480 / 6. change multiply sign to devide
therefore, x = 80
hope this answer will help you.

In engineering, the modulus of elasticity is a way to measure how much an object deforms along an axis when opposing forces are applied among that axis. The formula can be expressed as E=(F2−F1)L0(δ2−δ1)A , where E is the modulus of elasticity, F is the axial force, δ is a deformation measure, L0 is the original length of the object, and A is the cross-sectional area.
Step-by-step explanation:
Consider an engineering material of initial length Lo, Area (A), Modulus of elasticity (E) and applied a force P due to which change in the length of the material is δ2 from it’s original length (Lo)
Initial length of the material is Lo. Hence, at time t = 0 when no force applied on the material the length of the material will not change (i.e., at time t=0, δ1 = 0)
Modulus of elasticity of the material:
[tex]E=\frac{P \cdot L_{o}}{A\left[\delta_{2}-\delta_{1}\right]}[/tex]
Area of the material:
[tex]E=\frac{P \cdot L_{o}}{A\left[\delta_{2}-\delta_{1}\right]}[/tex]
[tex]A=\frac{P \cdot L_{o}}{E\left[\delta_{2}-\delta_{1}\right]}[/tex]
Length of the material:
[tex]E=\frac{P \cdot L_{0}}{A\left[\delta_{2}-\delta_{1}\right]}[/tex]
[tex]L_{0}=\frac{E \cdot A\left[\delta_{2}-\delta_{1}\right]}{P}[/tex]
Which expression represents the volume, in cubic

O (8)(6)(10) + (8)(6)(4)
O (8X6)\4)-(ex6)X6)
O (8X6)(4) –eX6)10)
Given:
The composite figure.
To find:
The volume of the given composite figure.
Solution:
Given composite figure contains a cuboid and a pyramid.
Length, breadth and height of the cuboid are 8, 6 and 4 respectively.
Volume of a cuboid is
[tex]V_1=length\times breadth\times height[/tex]
[tex]V_1=(8)(6)(4)[/tex]
Length and breadth of the pyramid is same as the cuboid, i.e., 8 and 6 respectively.
Height of pyramid = 10 - 4 = 6
Volume of a pyramid is
[tex]V_2=\dfrac{1}{3}\times length\times breadth\times height[/tex]
[tex]V_2=(\dfrac{1}{3})(8)(6)(6)[/tex]
The volume of composite figure is
[tex]V=V_1+V_2[/tex]
[tex]V=(8)(6)(4)+(\dfrac{1}{3})(8)(6)(6)[/tex]
It can be written as
[tex]V=(\dfrac{1}{3})(8)(6)(6)+(8)(6)(4)[/tex]

1. Andre bought a new bag of cat food. The next day, he opened it to feed his cat. The
graph shows how many ounces were left in the bag on the days after it was bought.
a. How many ounces of food were in
the bag 12 days after Andre bought
it?
b. How many days did it take for the
bag to contain 16 ounces of food?
c. How much did the bag weigh before
it was opened?
d. About how many days did it take for
the bag to be empty?
ounces of cat food
Using a linear function, it is found that:
a) 36 ounces of food were there after 12 days.
b) It took 24 days for the bag to contain 16 ounces of food.
c) The bag weighed 56 ounces before it was opened.
d) It took about 33 days for the bag to be empty.
What is the definition of a linear function?A linear function is defined according to the following rule:
y = mx + b
In which:
m is the slope of the function, also called the rate of change of the function, given by the change in y divided by the change in x.b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).From the graph of the function, we have that:
The intercept is of b = 56.The slope is of m = -40/24 = -1.6667, as in 24 days, the amount of food decayed from 56 ounces to 16 ounces, that is, it decayed 40 ounces.Hence the function for the amount of food after t days is given by:
A(t) = 56 - 1.6667t.
After 12 days, the amount is given by:
A(12) = 56 - 1.6667(12) = 36 ounces.
From the graph, we have that:
It took 24 days for the bag to contain 16 ounces of food.The bag weighed 56 ounces before it was opened. (y-intercept of the function = initial value).It took about 33 days for the bag to be empty. (x-intercept of the function).What is the missing information?The graph of the function is missing, and is given at the end of the answer.

Which of the following is equivalent to −3(2x + 5y) − 7(2q + 3p)? −6x − 15y − 14q − 21p −6x + 5y − 14q + 3p −6x + 15y − 14q + 21p −21(2x + 5y − 2q + 3p)
Answer:
−6x − 15y − 14q − 21p
Step-by-step explanation:
Let's simplify step-by-step.
−3(2x+5y)−7(2q+3p)
Distribute:
=(−3)(2x)+(−3)(5y)+(−7)(2q)+(−7)(3p)
=−6x+−15y+−14q+−21p
Answer:
=−21p−14q−6x−15y
The equation −3(2x + 5y) − 7(2q + 3p) is equivalent to −6x − 15y − 14q − 21p.Option A is correct.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,
−3(2x + 5y) − 7(2q + 3p)
For solving the equation we have to apply the arithmetic operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
First, open the bracket and multiply,
=−3(2x + 5y) − 7(2q + 3p)
=(−3)(2x)+(−3)(5y)+(−7)(2q)+(−7)(3p)
=−6x+−15y+−14q+−21p
Rearrange the equation as
=−21p−14q−6x−15y
Thus, the equation −3(2x + 5y) − 7(2q + 3p) is equivalent to −6x − 15y − 14q − 21p.Option A is correct.
