The value of q when q varies inversely with p is 2.
What is the value of q?The formula that can be used to represent inverse variation is:
p = k/q
Where:
p = dependent variable q = independent variable k = constant of proportionalityThe first step is to determine the value of the constant of proportionality
k = p x q
k = 15 x 4 = 60
Given the value of the constant of proportionality, the value of q can now be determined.
30 = 60/q
q = 60 / 30
q = 2

B. 1-4] > [1]
O c. 1 is farther to the right on a number line.
D. 1 has a lower absolute value.
Answer:
D. 1 has a lower absolute value
Step-by-step explanation:
D is the answer because -4 is negative and can never be more than a positive number like 1.
Answer:
D
Step-by-step explanation:
because 1 have 1 absolute value and -4 have 4 absolute value

Amy is trying to determine how many different outfits she can make. She has 4 bottoms 7 tops, 2 belts, and 5 pairs of shoes. Assuming she wears one of each item, how many different outfits can
she make?
Answer:
Amy puede hacer 4 conjuntos.
Step-by-step explanation:
La solución sería
Se sabe que un conjunto de vestir se compone de camisa o blusa, pantalones, zapatos y cinturones, aunque este ultimo es opcional.
Lo que haremos es esto, empezamos a coger una pieza de cada prenda para armar un conjunto.
Primer conjunto:
1 blusa, 1 pantalón, 1 cinturón, y 1 par de zapatos.
Y esto quedaría así: 3 pantalones, 6 blusas, 1 cinturón y 4 pares de zapatos.
Segundo conjunto:
1 blusa, 1 pantalón, 1 cinturón y 1 par de zapatos.
Esto quedaría así: 2 pantalones, 5 blusas, 0 cinturones, 3 pares de zapatos. Sabemos que el cinturón es opcional, así que podemos continuar.
Tercer conjunto:
1 blusa, 1 pantalón y un par de zapatos.
Esto quedaría así: 1 pantalón, 4 blusas, 0 cinturones y 3 pares de zapatos.
Cuarto conjunto:
1 blusa, 1 pantalón y un par de zapatos.
Esto quedaría así: 0 pantalones, 3 blusas, 0 cinturones y 2 pares de zapatos. Como en un conjunto el pantalón es prioridad, al no tener más pantalones los conjuntos quedarían hasta aquí.
¡Recuerda!
No es lo mismo organizar tu ropa en conjuntos, a que hagas variaciones con ella.

Consider the equation q = 4 +0.8p.
=
What value of p would make the equation to
12?
Answer:
p=10
Step-by-step explanation:
q = 4 +0.8p
Let q = 12
12 = 4 +0.8p
Subtract 4 from each side
12-4 = 4+.8p -4
8 = .8p
Divide each side by .8
8/.8 = .8p/.8
10 =p

Answer:
(x, y) = (9, 17)
Step-by-step explanation:
Any two pairs of equations can be used to form a system of equations that will give appropriate values of x and y. Let's set the upper and lower left expressions equal to the middle one.
2x +3y -20 = 4x +5y -72 . . . . upper left = middle
52 = 2x +2y . . . . . . . . add 72-2x-3y
x + y = 26 . . . . . . . . . . divide by 2
and ...
5x -2y +38 = 4x +5y -72 . . . . lower left = middle
110 = -x +7y . . . . . . . . . . . . . add 72-5x+2y
Now we have two equations in two unknowns that will give us the common values of x and y. Adding these equations eliminates x and gives the value of y:
(x +y) +(-x +7y) = (26) +(110)
8y = 136 . . . . . . . . simplify
y = 17 . . . . . . . . . divide by 8
x = 26 -y = 26 -17 = 9
The values of x and y that make all of these expressions equal are ...
(x, y) = (9, 17)
The value they are equal to is ...
2x +3y -20 = 2(9) +3(17) -20 = 18 +51 -20 = 49
__
Check
upper right = 9 -4(17) +108 = 9 -68 +108 = 49
lower right = 3(9) -17 +39 = 27 -17 +39 = 49

Answer:
1a) A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound.
1b)An ionic compound formed by acid-base reactions and without those ions is called a salt. Water is definitely one of the most important inorganic compounds to all living things. It is a compound comprised of two hydrogen atoms and one oxygen atom.
The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
2a)Regulates body temperature. Moistens tissues in the eyes, nose and mouth. Protects body organs and tissues. Carries nutrients and oxygen to cells.
2b)If a cell is seriously deprived of water,
this lack of water would most likely affect
the cell's enzymes because:
• The cytoplasm and plasma
membrane would not function
properly
Both the plant and animal cell needs
water in order to perform their basic
functions which include transport of
materials, waste distribution, production
of genetic information, and many more.
As a result of this, we can see that there
would be a serious problem if any
of these cells are deprived of water
which would lead to the cytoplasm and
plasma membrane to partially shut
down because they would not be able to
engage in protein synthesis and other
important functions.
3a)Carbohydrates provides energy rich for organic compounds made of elements carbon, hydrogen and oxygen. The lipids contain the element nitrogen. The carbohydrates contain the only elements carbon, hydrogen, and oxygen.
3b)Organic nitrogen occurs in many forms, including amino acids, proteins, nucleic acids, nucleotides, and urea.
3c)A carbohydrate has only Carbon, Hydrogen and Oxygen, with the hydrogen and oxygen in the ratio 2:1. A protein is made of amino acids. ... So without nitrogen atoms the compound can not be a protein.
A triangle has angle measurements of 66°, 66°, and 48°. Is this triangle isosceles?
Answer:
yes
Step-by-step explanation:
The 2 base angles of an isosceles triangle are congruent.
66° + 66° + 48° = 180° ( sum of angles in a triangle )
Thus the triangle is isosceles with base angles = 66° and vertex = 48°
An angle bisector of a triangle divides the opposite side of the triangle into segments2 cm and 5cm long. The second side of the triangle is 7.5 cm long. Find all possible lengths for the third side of the triangle.
Answer:
3 cm or 18.75 cmStep-by-step explanation:
Let the third side is x.
According to Triangle-angle-bisector theorem, we have the possible ratios:
x/7.5 = 2/5or
x / 7.5 = 5/2Solve for x in each case:
1)
x = 7.5*2/5 = 3 cm2)

im having trouble solving this. y=5(x-3)
Hi there!!
If you need X to be solved then the answer is X=Y over 5+3 and if your looking for the answer for Y then the answer is Y=5x−15
When you are solving for X you will need to use the distributive property so you can multiply 5 by X-3.
Y=5x-15. Once you've done that then you need to swap sides so all of the variables are on the same side as each other (they need to be on the left side) 5x-15=Y.
Then you need to add 15 to both of the sides to make it look like this ->5x=Y+15
When that's done you then need to divide both sides by 5 so it then looks like this when done.
5x over 5= Y+15 over 5
When you divide this by 5, it then undoes the multiplication by 5.
X= Y+15 over 5
Finally, you need to divide Y+15 by 5
X=Y over 5 plus 3
When solving for Y, all you will need to do is use the distributive property to multiply 5 by X-3.

Napoleon's route through the alps involved a climb of 6km and a descent of 4km. His army travelled twice as fast downhill as it did uphill, the whole journey took 8 hours. How long did it take to reach the top?
Answer:
6 hours.
Step-by-step explanation:
since that is true we can use trial and error. if every km took an hour it would take six hours up and 4 hours down but they said they were twice as fast going down so that means it would take 2 hours going down. 6 add 2 is 8 which is our total meaning that 6 hours is the right answer
