In a certain chemical, the ratio of zinc to copper is 3 to 16 A jar of the chemical contains 528 grams of copper. How many grams of zinc does it contain?
Answer:
99 grams of zinc
Step-by-step explanation:
Ser up a proportion
[tex]\frac{zinc}{copper}[/tex] = [tex]\frac{zinc}{copper}[/tex] Put in the ration and the actual amount of copper i and solve for the actual number of zinc
[tex]\frac{3}{16}[/tex] = [tex]\frac{z}{528}[/tex] cross multiply to solve for z
16z = 3(528)
16z = 1584 Divide both sides of the equation by 16
z = 99

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.
Which definition of inequality is the best?The meaning of inequality
A social discrepancy is one example of a characteristic that is unequal or uneven. b: unequal opportunity or distribution.
A disparity in size, quantity, quality, social standing, or another aspect is what is meant by the term "inequality." When you have ten of something and someone else has none, that is an instance of inequality.
A number = n 12
multiplied by a number = n+12
which is 32 less than the number = 3n-32
n+12 =3n-32
44 =2
The result is equal to 2n n=22.

you take a break from doing your physics homework and go to the grocery store to buy pasta. the store is out of your favorite kind of pasta so, instead, you buy pasta that is the same shape as your usual pasta but is twice as big in every dimension (twice as long, twice as wide, etc.). one box of the bigger pasta pieces has the same net weight as one box of your usual pasta.
In linear equation, oil required to cover oil all the pieces in one box of big pasta with same thin layer of oil = 1/2 of the oil.
What are a definition and an example of a linear equation?
A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.Let the dimensions of one piece of your favorite kind of pasta be l, b, h.
Volume of one piece of pasta = l b h
Surface area of one piece of pasta = 2( lb + bh + lh)
Let the no of pasta piece in the box ( favorite one ) be 'n' = .
Total volume = n × lbh
Total Surface area = n . 2( lb + bh + lh)
In the bigger size pasta box dimensions of one piece of of pasta 2l , 2h , 2b .
∴ Volume of one piece of pasta = 2l × 2b × 2h = 8lbh
Surface area of one piece of pasta = 2( 4lb × 4bh × 4lh)
= 2 × 4 ( lb × bh × lh )
Let the no of pasta pieces in the bigger pasta box in m.
Total volume of pasta = m × 8lbh
total surface area = m . 4 × 2 ( lb × bh × lh )
the total volume of pasta is also same in the box.
mass = density × volume
D × m .8 lbh = D × n . lbh
m = n/8
total surface area of pastas in bigger pasta box = m × 4 × 2 ( lb × bh × lh)
= n/8 × 4 × 2 ( lb × bh × lh )
= n/8 × 1/2 × n× 2 ( lb × bh × lh )
= 1/2 × surface area (total) of small pasta
∴ oil required to cover oil all the pieces in one box of big pasta with same thin layer of oil = 1/2 of the oil

The duration of shoot would be 2 hours and Either stylist would cost $282 if the shoot lasted 2 hours.
A fashion photographer needs to hire a stylist to prepare his models.
Let the number of hours stylist take = x
Jayla charges $156 for showing up, plus $63 per hour. So, this can be mathematically written as ,
156 + 63x equation 1
Sally charges $158 plus $62 per hour. So, this can be mathematically written as ,
158 + 62x equation 2
As per the question, the expected duration of his photo shoot, either stylist would cost him the same amount. So we can equate equation 1 and equation 2. On equating equation 1 and equation 2 , we will get
156 + 63x = 158 + 62x
⇒ x = 2
So, the duration would be 2 hours.
Jayla cost = Sally cost = 156 + 63x = 156 + (63 × 2) = 282

Part 2: Find the volume of the shipping box using the total number of fish food cubes. Step 1: Find the volume of the fish food cube. Remember to include units. Volume of the fish food cube = _____ × _____ × _____ = __________ Step 2: Find the volume of the shipping box using your answer from Part 1. Remember to include units. Volume of the shipping box = _____ × _____ = __________ Part 3: Find the volume of the shipping box using a volume formula. Remember to include units. V = l × w × h = _____ × _____ × _____ = __________ Are your answers for the volume of the shipping box in Parts 2 and 3 equal? Why or why not?
The volume of one fish food cubes is: 1/64 ft³
Using the volume formula, the volume of the shipping box is: 15/4 × 3 × 13/4 = 585/16 ft³
The number of fish food cubes that can be packed in the shipping box is: 2,340 fish food cubes.
What is the Volume of a Box and a Cube?The volume of a box = length × width × height
A cube has equal side lengths, therefore, the volume of a cube = (side length)³ = side length × side length × side length.
We are given that the fish food cubes have side lengths of 1/4 ft. Therefore:
Volume of fish food cubes = 1/4 × 1/4 × 1/4
Volume of fish food cubes = (1 × 1 × 1)/(4 × 4 × 4)
Volume of fish food cubes = 1/64 ft³
Using the volume formula, we are given the parameters of the box as:
Length (l) = 3¾ = 15/4 ft
Width (w) = 3 ft
Height (h) = 3¼ = 13/4 ft
Therefore,
Volume of shipping box = 15/4 × 3 × 13/4
Volume of shipping box = (15 × 3 × 13)/(4 × 4) = 585/16 ft³
The number of fish food cubes that can be packed in the shipping box = volume of shipping box/volume of one fish food cube
= 585/16 ÷ 1/64
= 585/16 × 64/1
= (585 × 64)/(16 × 1)
= 37,440/16
= 2,340 fish food cubes.

A piece of foam padding has a volume of 1,500 cm³ and a mass of 200 g.
What is the density of the foam?
The density of the piece of form will be 0.14 g/cm³.
What is density?Density is defined as the ratio of the mass of the object to the volume of the object. It does not depend upon the whole mass it only depends upon the mass per unit volume.
Volume is defined as the space occupied by the object in the three-dimensional space.
Given that a piece of foam padding has a volume of 1,500 cm³ and a mass of 200 g.
The density of the foam will be calculated as,
D = mass / Volume
D = 200 / 1500
D = 0.1333333333 or 0.14 g/cm³

zeros of f(x) algebraically.
Answer:
x = -2, -1, 8Step-by-step explanation:
You want the zeros of f(x) = x³ -5x² -22x -16, given that a factor is x+2.
FactorsUsing synthetic division (see attachment), we find the quadratic factor to be (x² -7x -8), so we have ...
f(x) = (x +2)(x² -7x -8)
The quadratic can be factored using our knowledge of the divisors of -8 to give ...
f(x) = (x +2)(x +1)(x -8)
ZerosThe zeros of f(x) are the values of x that make these factors zero:
x = -2, -1, 8 . . . . . zeros of f(x)
__
Additional comment
We know the product of binomial factors is ...
(x -a)(x +b) = x² -(a-b)x -ab
This means we can factor the quadratic by looking for factors of 8 that have a difference of 7. We know that 8 = 8·1 and that 8-1=7, so the values of 'a' and 'b' we're looking for are a=8, b=1.
The "zero product rule" tells you a product is zero only if one of the factors is zero. That is how we know to look for the zeros of the binomial factors of f(x). For example, x+2=0 ⇒ x=-2 is a zero of f(x). (The remainder of 0 in the synthetic division also tells us f(-2)=0.)

He will need 14 boxes which can store can store 8 tins of coffee and 6 boxes that can store 12 tins of coffee.
let us assume:
Number of 8- tin boxes= x
Number of 12- tin boxes= y
we are given the condition that total number of boxes are 20, so-
x+y=20
⇒ x= 20-y
We are also given the condition that he has 184 tins of coffee, so-
8x+12y= 184
⇒ 8(20-y) + 12y = 184
⇒ 160 -8y +12y = 184
⇒ 4y= 24
⇒ y=6
⇒ x=20 -y
⇒ x= 20 - 6
