Answer:
20/5=4/1= 4 pounds per gallon.
Step-by-step explanation:
I got that answer by dividing 20/5 and you will get 4. Then you will divide 4/1 because unit rates your supposed to have a denominator of 1. And your answer should be 4 pounds per gallon.

Answer:
(x +1)² = 4(D) x = -1 ±2Step-by-step explanation:
Start by getting the x-terms on one side of the equal sign. We can do that by subtracting x from both sides.
3 = x² +2x
Now, add the square of half the x-coefficient.
3 +1 = x² +2x +1
(x +1)² = 4 . . . . . . . . write as a square in the desired form
__
To solve, take the square root, and add the opposite of the left-side constant.
x +1 = ±2
x = -1 ±2 . . . . . . matches choice (D)

HELP Use either law of sines or law of cosine. Need help on this problem! show work please!
Answer: x = 15.035677095729 approximately
Round this however you need to.
=================================================
Explanation:
I'm assuming you want to find the value of x, which your diagram is showing to be the length of segment QR.
If so, then we'll need to find the measure of angle Q first. Using the law of sines, we get the following:
sin(Q)/q = sin(R)/r
sin(Q)/PR = sin(R)/PQ
sin(Q)/13 = sin(85)/19
sin(Q) = 13*sin(85)/19
sin(Q) = 0.6816068987
Q = arcsin(0.6816068987) ... or ... Q = 180-arcsin(0.6816068987)
Q = 42.9693397461 ... or ... Q = 137.0306602539
These values are approximate.
----------------
Now if Q = 42.9693397461 approximately, then angle P is
P = 180-Q-R
P = 180-42.9693397461-85
P = 52.0306602539
Similarly, if Q = 137.0306602539 approximately, then,
P = 180-Q-R
P = 180-137.0306602539-85
P = -42.0306602539
A negative angle is not possible, so we'll ignore Q = 137.0306602539
----------------
The only possible value of angle P is approximately P = 52.0306602539
Let's apply the law of sines again to find side p, aka segment QR
sin(P)/p = sin(R)/r
sin(P)/QR = sin(R)/PQ
sin(52.0306602539)/x = sin(85)/19
19*sin(52.0306602539) = x*sin(85)
19*sin(52.0306602539)/sin(85) = x
x = 15.035677095729
This value is approximate.
Round this value however you need to.

1. Melanie invested $12,200 at 4.8% interest compounded semiannually, and she wants to know how much her investment will be worth in 8 years. (5 points: Part I – 1 point; Part II – 2 points; Part III – 1 point; Part IV – 1 point)
Part I: What is the periodic interest rate of Melanie's investment?
Part II: How many compounding periods does Melanie's investment offer in a year? How about in 8 years?
Part III: What expression can Melanie write to figure out how much her investment will be worth in 8 years?
Part IV: How much will Melanie's investment be worth in 8 years?
Answer:
Part I
4.8% compounded semiannually means 4.8%/2 = 2.4% per 6 month periodPart II
Period is 6 months, so 2 periods in a year and 2*8 = 16 periods in 8 yearsPart III
A = $12200*(1 + 0.024)^16Part IV
A = $12200*(1 + 0.024)^16 = $17830.32Antonio writes the equation 80.4 ÷ d = 0.0804.

A submarine started 30 feet below the surface of the water. It is now 10 feet below the surface. What integer represents the change in depth?
Answer:
-20 feet
Step-by-step explanation:
change in depth = number of feet below the surface + number of depth on the surface
Because the submarine is below surface, a value of -30 would be given
-30 + 10 = -20 feet
The box plot show the lengths of the songs on two digital music players in minutes .Which statement is best supported by the information in the box plots ?
Solution :
In the figure, the box plot represents the lengths of the songs of the two digital music players that is in minutes.
From the figure, we can see that for the music player Y, the interquartile range of the data is small.
And the interquartile range of data is more for the music player X.
So, we can conclude that the interquartile range of data is greater for Music player X than the interquartile range data of music player Y.

Para llenar una piñata con dulces se necesitan 8.3 libras de dulces ¿cuantos kilogramos se tuvieron que comprar?
Answer:
Tuvieron que comprar 3.73 kg.
Step-by-step explanation:
Para obtener la respuesta, tienes que encontrar a cuántos kilogramos equivalen 8.3 libras de dulces y para esto puedes utilizar una regla de tres teniendo en cuenta que 1 libra es igual a 0.45 kilogramos:
1 libra → 0.45 kilogramos
8.3 libras → x
x=(8.3*0.45)/1=3.73 kg
De acuerdo a esto, la respuesta es que tuvieron que comprar 3.73 kg.

HELP PLS
will give brainliesy!
Answer: 60 degrees
if angle dgc equals 90 (the little square means right angle which is 90 degrees) that means dga equals 90 too (because they are supplementary angles which equal 180 together)
90 - 30 = 60 (minus 30 bc 30 needs to be subtracted in order to find angle dge)
vertical angles are equivalent so x = 60
:)
Answer:
60
Step-by-step explanation:
because the unmarked angle is vertical pairs with the 90º, we know it is 90º
xº=180º-30º-90º
=90º-30º
=60º

fudge or caramel toppings. Which tree diagram shows all possible flavor combinations of sundaes with one flavor of ice cream and one topping?
Answer:
top left aka the first option
The tree that shows the correct combination of one flavor of ice cream and one topping is the the first tree.
What is tree diagram ?A tree diagram is a tool in the fields of general mathematics, probability, and statistics that helps calculate the number of possible outcomes of an event or problem, and to cite those potential outcomes in an organized way.
Tree diagrams, also known as probability trees or decision trees, are quite versatile and may be useful in many fields, including finance.
A tree diagram lets a user start at a single point and make mutually exclusive decisions or experience mutually exclusive events to follow a path down the branches of the tree. Using a tree diagram is simple once you assign the appropriate values to each node.
From the question, and the definition it is clear that vanilla splits into fudge and caramel and chocolate to sprinkles.
Hence A is the correct option.

If f(x) = 2x^2 - 4x - 3' and `g(x) = (x - 4)(x + 4)", find 'f(x) - g(x).
Answer:
B
Step-by-step explanation:
f(x) - g(x)
= 2x² - 4x - 3 - (x - 4)(x + 4) ← expand using FOIL
= 2x² - 4x - 3 - (x² - 16) ← distribute by - 1
= 2x² - 4x - 3 - x² + 16 ← collect like terms
= x² - 4x + 13 → B
