Milk is on sale for 40% off when it is normally $3.75 per gallon. How much will a gallon of milk cost?
The discounted price for milk is $_____(Round to the nearest cent.)
Answer:
$2.25 is the discounted price for each gallon.
Step-by-step explanation:
So you take 40% and convert it into decimal form, which is 0.4. Then you take $3.75 x 0.4 = 1.5. Then subtract $1.50 from $3.75, and that equals $2.25 each gallon.

patch has an area of 1 ft?. He wants to put some of the
patches together to make square quilts.
Which areas listed below are possible areas of the square
quilts Garrett can make? What side length will each of
those square quilts have? Show your work.
The areas listed that are possible areas of the square quilts Garrett can make will be 0.25, 0.81, etc.
How to calculate the area?Your information is incomplete as your didn't give the areas listed. Therefore, an overview will be given.
It should be noted that the area of a square is simply gotten by multiplying the side by itself. For example, if a side is 4cm, the area will be 4 × 4 = 16cm².
In this case, we are told that each patch has an area of 1 ft. Therefore, the square of the area gotten should not be more than 1 feet. Possible values include:
0.5 × 0.5 = 0.25
0.9 × 0.9 = 0.81

says, “To determine how many pounds of flour are in one bun, divide
33.2 by 1,000. The shortcut is to add 3 zeros to the left side of the
number, so each bun has 0.000332 pound of flour in it.” Explain and

what is the opposite of -3.4
Answer:
3.4
Step-by-step explanation:
The opposite of a number is the same as the additive inverse of the number.
Two numbers are opposites, or additive inverses, if they add to zero.
For a positive or a negative number, just change its sign to find its opposite. For zero, its additive inverse is zero.
The opposite of -3.4 is 3.4.
Answer: 3.4
The opposite of a positive number is a negative number.
The opposite of a negative number is a positive number.
-3.4 is a negative number, so its opposite is a positive number.
Hence, the answer is 3.4

Write the equation of a line of the table below.
Pls help will give brainliest
Answer:
slope: 5
y-intercept: 0
Equation: [tex]y=5x[/tex]
Step-by-step explanation:
First, lets find the slope.
Every time we have an increase in [tex]x[/tex], we have an increase in [tex]y[/tex].
To find that change, we will divide the changes in [tex]y[/tex] using two points.
I will be using the points [tex](1,5), (2,10)[/tex]
[tex]\frac{10-5}{2-1}[/tex]
[tex]=5/1[/tex]
[tex]=5[/tex]
Therefore, the slope is 5.
Next, lets find the y-intercept. The y-intercept is where the line goes through the y-axis.
We can go back 1 x-value (since when x = 1, y = 5)
Subtracting our slope (5) from the y-value for 1, we get:
[tex]y=0[/tex]
Therefore, the y-intercept is 0.
Finally, lets find the equation.
Linear equations are in the form [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.
Plugging those values in we get: [tex]y=5x+0[/tex]
Which will be simplified down to [tex]y=5x[/tex]

Natalie is playing a game using a fair coin. Contestants win the game if the fair coin lands tails up. The theoretical proabaility that the coin will lamd tails is ? If 250 contestants play the game, about of them are expected to win
The theoretical probability of landing on tails is P = 0.5, and out of the 250 contestants, around 125 will win the game.
About how many contestants will win?
The coin has two possible outcomes, so if it is a fair coin, the probability for each of the outcomes will be 0.5 (this is the theoretical probability for a fair coin, where all the outcomes have the same probability).
Now, we know that a person wins if the coin lands tails up, and the probability of landing on tails is 0.5
Then, for a sample N, we can expect that about 0.5*N of the participants win.
In this case, the sample is 250, then we can expect that:
0.5*250 = 125
Around 125 of the contestants win the game

A large box of crackers away 20 Oz if James needs 3 pounds of crackers for a party how many boxes of crackers should he buy
Answer:
James will need to buy 3 boxes of crackers for the party.
Step-by-step explanation:
remember: 16oz=1 pound
If James needs 3 pounds of crackers, and each box is 20oz, that means each box is a little over 1 pound. (1.25 pounds to be exact). So, we know that he needs to buy 3 boxes of crackers. This is because 20×3=60 ounces which is 3.75 pounds. Meaning, 3 boxes is the correct answer since we can't cut a box in half.

Write an expression equivalent to/that has two terms. 2x - 1/2 (10 - 4x)
Answer:
4x - 5
Step-by-step explanation:
To make this 2 terms, we'll have to first identify if we have to distribute anything.
Since 10 - 4x is inside a parenthesis and [tex]\frac{1}{2}[/tex] is beside that, we know that we'll have to distribute the expression.
[tex]-\frac{1}{2}[/tex] (10 - 4x) = [tex]-\frac{10}{2}[/tex] + [tex]\frac{4}{2}[/tex]x = -5 + 2x.
Then, combine like terms:
2x - 5 + 2x = 4x - 5.
Remember, the coefficient always goes before the constant.
Your answer should be 4x - 5.

Olga just got a new job, and she is looking to lease a car. Dealer A offers her a $2400 trade-in on her old car, with lease payments of $360 a month. Dealer B offers a trade-in of $2000 with payments of $320 a month. Olga wants to lease the car for only 6 months. Which deal is better for her?
Answer:
$2000 with payments of $320 a month
Step-by-step explanation:
360 x 6 = 2160
2160 + 2400 = 4560
320 x 6 = 1920
1920 + 2000 = 3920
Answer:

Step-by-step explanation:
A: 360×6=2160
2400-2160=240
they save $240
B: 320×6=1920

The expression 11.5+ (4+ (-6.5)) is to be rewritten by applying the commutative
and associative properties of addition. If you use each property only one time,
which expression could be the result?
O (11.5+ (-6.5)) + 4
O 11.5+ (2.5)
O (4+ (-6.5)) +11.5
O (11.5 + 4) + (-6.5)
Answer:
C. [tex](4+ (-6.5)) +11.5[/tex]
Step-by-step explanation:
Just exchange:
11.5 + (4 + ( - 6.5 ) )
⇒ (4+ (-6.5)) +11.5
After applying the property the expression would be (4+ (-6.5)) +11.5.
What is Associative property?Changes to the order of the addends have no effect on the sum, according to the associative feature of addition.
For example, ( 2 + 3 ) + 4 = 2 + ( 3 + 4 ) or (2 + 3) + 4
Given:
11.5+ (4+ (-6.5))
In Above case we can use the Associative property over addition.
For this we just need to exchange the position of number along with their signs.
So, 11.5+ (4+ (-6.5))
= (4+ (-6.5)) +11.5
Hence, after applying the property the expression would be (4+ (-6.5)) +11.5.

A savings account starts with $420. After 6 years of continuously compounding at an interest rate, r, the account has a balance of $1,300. What is the interest rate percentage (do not type % it is already there)? Round answer to the nearest hundredth.
Answer:
18.83% (nearest hundredth)
Step-by-step explanation:
Continuous Compounding Formula
[tex]\sf A=P(e)^{rt}[/tex]
where:
A = amountP = principal (initial amount)e = mathematical constant ≈ 2.7183r = interest rate (in decimal form)t = time in yearsGiven:
A = $1,300P = $420t = 6 yearsSubstituting given values into the formula:
[tex]\sf \implies 1300=420(e)^{6r}[/tex]
[tex]\sf \implies \dfrac{1300}{420}=e^{6r}[/tex]
[tex]\sf \implies e^{6r}=\dfrac{65}{21}[/tex]
Taking natural logs of both sides:
[tex]\sf \implies \ln e^{6r}=\ln \dfrac{65}{21}[/tex]
[tex]\sf \implies 6r\ln e=\ln \dfrac{65}{21}[/tex]
[tex]\sf \implies 6r(1)=\ln \dfrac{65}{21}[/tex]
[tex]\sf \implies 6r=\ln \dfrac{65}{21}[/tex]
[tex]\sf \implies r=\dfrac16 \ln \dfrac{65}{21}[/tex]
[tex]\sf \implies r=0.1883108054...[/tex]
Therefore, the interest rate is 18.83% (nearest hundredth)

In the accompanying diagram of a unit circle, the ordered pair (x,y) represents the point where the terminal side of 0 intersects the unit circle. If 0=150, what is the value of x.
A.
B.
C.
D.
Answer:
Below in bold.
Step-by-step explanation:
tan 150 = -tan 30
= -1/√3 = y/x (1)
This is a unit circle so the hypotenuse = 1.
so sin 150 = y/1 = y
y = 1/2
So substituting in equation (1)
1/2 / x = -1/√3
-x = √3/2
x = -√3/2.
The value of x in the unit circle is -√3/2.
Option B is the correct answer.
What is a circle?A circle is a two-dimensional figure with a radius and circumference of 2pir.
The area of a circle is πr².
We have,
Since the angle is 150 degrees, we know that it is in the second quadrant, where the x-coordinate is negative and the y-coordinate is positive.
Since the circle has a radius of 1, the y-coordinate is sin(150) = 1/2.
To find the x-coordinate, we can use the formula x = cos(θ), where θ is the angle in radians.
To convert 150 degrees to radians, we multiply by π/180:
150 degrees x π/180 = 5π/6 radians
So,
x = cos(5π/6) = -√3/2.
Therefore,
The value of x is -√3/2.
