The sum of two fractions is 2/3.
One fraction is 1/2.
What is the other fraction?
Answer:
0.5/3
Step-by-step explanation:
1/2 can be turned into 2/4, which means that to be 1/3, it has to be 1.5/3. 1.5/3 + 0.5/3 equals 2/3.

Step-by-step explanation:
f(x) = 2x + 3 and g(x) = 24 – X.
Solve the equation f(x) = g(14).
Answer:
x = 3.5
Step-by-step explanation:
f(x) = 2x + 3
g(x) = 24 – x
-> g(14) = 24 - 14
-> g(14) = 10
f(x) = g(14) (Given)
-> 2x + 3 = 10
-> 2x = 10 - 3
-> 2x = 7
-> x = 7/2
-> x = 3.5
A pizza dough recipe has a ratio of 5 cups of flour to 2 cups of water. There are ?
cups of flour per cup of water
Answer:
2.5 cups of flour per cup of water.
Step-by-step explanation:
We can divide the entire recipe by two, to get the amount of flour to 1 cup of water.
5/2 = 2.5
2/2 = 1
Therefore, 2.5 cups of flour needs 1 cup of water.
Answer:
There are 2.5 cups of flour per cup of water
Step-by-step explanation:
Step 1: Find the ration
Cups of Flour : Cups of Water

Answer:
minor arc
Step-by-step explanation:
This is a vocabulary question:
major arc: has a measure more than 180°minor arc: has a measure less than 180°semicircle: has a measure of exactly 180° (connects the ends of a diameter)__
Arc EA is a minor arc.
_____
Additional comment
In general, unless the two named points are the ends of a diameter, the arc is a minor arc. A major arc will generally be defined by designating a third point on the long arc connecting the same points on the circumference. For example, EDA, ECA, and EBA all designate the major arc connecting points E and A. (We can also use the descriptor, "major arc EA.") Without any of these extras designating the major arc, EA is considered to be the minor arc.
Use the shell method to write and evaluate the definite integral that represents the volume of the solid generated by revolving the plane region about the y-axis.
y = 3 − x
The volume of the solid generated by revolving the plane region y=3−x about the y-axis is 9π cubic units.
What is integration?It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.
We have a function:
y = 3 - x
From the graph:
Shell radius = y
Height = 3 - y
From the shell method, we can write the integral as follows:
[tex]\rm Volume =2\pi\int\limits^0_{-3} {y(3-y)} \, dy[/tex]
[tex]\rm Volume =2\pi\int\limits^0_{-3} {(3y-y^2)} \, dy[/tex]
After solving the above definite integral, we will get volume:
Volume = 9π cubic units
Thus, the volume of the solid generated by revolving the plane region y=3−x about the y-axis is 9π cubic units.

You need a 55% alcohol solution. On hand, you have a 50 mL of a 25% alcohol mixture. You also have 60% alcohol mixture. How much of the 60% mixture will you need to add to obtain the desired solution?
Answer:
300 mL
Step-by-step explanation:
There is a simple diagrammatic way to solve mixture problems, illustrated in the attachment. In the left column are the available solution percentages. In the center is the percentage of the desired mix. In the column to the right of that are the diagonal differences between the desired value and the constituent values. Those differences represent the proportions of the constituents on the same horizontal line.
__
Here, that means 30 parts of 60% solution are needed for 5 parts of 25% solution. Since we have 50 mL of 25% solution, we can multiply these ratio values by 10 mL to find the quantities needed. That has been done here in the right-most column.
300 mL of 60% solution are needed to obtain the desired mixture.
__
Additional comment
If you want to write an equation, you can let x represent the quantity of high-concentration solution needed. Then the amount of alcohol in the mix is ...
0.60x +0.25(50) = 0.55(x +50)
0.05x = 0.30(50) . . . . . . . subtract 0.55x+0.25(50)
x = 300 . . . . . . . . . . . . mL of 60% solution needed

The cost of gas increases monthly at a rate of 3.2%. If gas cost $1.75 today. How much will it cost in 3 years? ( round to the nearest cent (2 decimal places) )
Answer:
$1.92
Step-by-step explanation:
present cost = $1.75
time = 3 years
rate = 3.2%
cost after three years = present cost (1 +[tex]\frac{R}{100}[/tex] )^3
=$1.75 ([tex]\frac{103.2}{100}[/tex])^3

You deposit $8,400 in an account earning 3.6% interest compounded monthly.
a. How much will you have in the account in 20 years?
b. How much interest will you earn?
Answer:
A = $17,238.65
I (interest) = $8,838.65
Step-by-step explanation:
Using the formula A = P(1 + r/n)^nt
A = $17,238.65
A = P + I where
P (principal) = $8,400.00
I (interest) = $8,838.65
First, convert R as a percent to r as a decimal
r = R/100
r = 3.6/100
r = 0.036 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 8,400.00(1 + 0.036/12)^(12)(20)
A = 8,400.00(1 + 0.003)^(240)
A = $17,238.65
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $8,400.00 at a rate of 3.6% per year compounded 12 times per year over 20 years is $17,238.65

The ceiling of Stacy's living room is a square that is 22 ft long on each side. Stacy knows the diagonal of the ceiling from corner to corner must be longer than 22 ft, but she doesn't know how long it is.
Solve for the length of the diagonal of Stacy's ceiling in two ways:
(a) Using the Pythagorean Theorem.
(b) Using trigonometry.
Round each answer to the nearest whole number and make sure to show all your work. (Hint: the answers should be the same!)
Answer:
I don't understand trig very well but I do get pythagorean theorem, which I can help with. Your final answer will end up being 31.
Step-by-step explanation:
First off the formula for pythagorean theorem is a^2 + b^2 = c^2
We know that C stands for the hypotenuse so we want to know what C is.
A and B are both 22 so our equation turns into 22^2 + 22^2 = c^2
22 squared is 484 which leads to 484 + 484 = c^2
484 + 484 = 968
968 is our C^2 but we still need to find the square root
The square root of 968 is 31.11269837... and a whole lot of other numbers
You round that out to 31 and get the length of your diagonal
