What are gigabytes?gigabytes (GB) – pronounced with two hard Gs – is a unit of storage capacity equal to approximately 1 billion bytes. In decimal form (base 10), a gigabyte is exactly one billion bytes. In binary form, a gigabyte is 230 bytes or 1,073,71,82 bytes. Giga comes from the Greek word for giant. Werner Buchholz is credited with coining the term byte in 1956 and helped design IBM's 7030 Stretch, the first transistorized supercomputer.
gigabytes has been a common unit of measurement for data storage products since the mid-1980s. In recent years, terabytes (TB) have become a more common measure of storage capacity, especially for hard drives and solid-state drives.

Find the Greatest Common Factor (GCF):
70x³z, 45y4z²
The greatest common factor for the given expression is 5z.
What is GCF?
The greatest common factor, which is the product of two or more numbers, is the largest number (GCF). A natural number is created by dividing them by the biggest number (factor). There are a few factors that both share once all the number's factors have been identified. The greatest common factor is the one with the largest number among the common factors. The highest common factor is another name for the GCF (HCF). The highest number that is a factor of all the numbers is known as the greatest common factor of two or more numbers.
Given, the first expression is: y₁ = 70x³z = 5z.14x³ -(i)
Also, the second expression is: y₂ = 45y4z² = 5z.36yz -(ii)
Comparing (i) and (ii), the greatest common factor for y₁ and y₂ is 5z.
Thus, the greatest common factor for the given expression is 5z.

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

Not drawn accurately
Bunting has been hung in a straight line between a wall and a house, then the height, P, of the house P = 6.61 m.
Third angle in a triangle = 180 - (90+36)
= 180-126
= 54°
So,
Third angle in a triangle = 54°
We can use Sin rule,
Then, we get,
[tex]\frac{Sin A}{BC} =\frac{Sin B}{AC} =\frac{Sin C}{AB}[/tex]
Based on the given condition,
We can write,
Sin A = 54°
Sin B = 36°
BC = 5.47
Then,
Sin 54°/5.47 = Sin 36°/AB
Hence, Sin 54° = 0.8090
Sin 36° = 0.5877
[tex]\frac{0.8090}{5.47} =\frac{0.5877}{AB}[/tex]
AB = [tex]\frac{0.5877 * 5.47}{0.8090}[/tex]
AB = [tex]\frac{3.2147}{0.8090}[/tex]
AB = 3.97 m
So,
Height , P = 2.64 + 3.97
P = 6.61 m.
Therefore,
We can use triangle formula, then the height, P, of the house P = 6.61 m.

If f(x)= x³ - 5x² - 22x - 16 and x + 2 is a factor of f(x), then find all of the
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.)

Which of the following proves these triangles are congruent?
A - Neither

The statement that proves the congruency of the two triangles is (c) ASA
The given parameter is the two triangles in the figure
For the angles or the sides of the triangles to be congruent, the sides or the angles must be marked with the same identifier
Using the above as a guide,
Two corresponding angles in the triangles are marked with the same symbol
This is represented as AA i.e. Angle-Angle
Also, the triangles share a common side length
This is represented with S i.e. Side
This common side length is between the angles
So, we have

John has two types of boxes. The smaller box can store 8 tins of coffee and the bigger box can store 12 tins of coffee. If the total number of boxes is 20 and he has 184 tins of coffee, by forming a pair of simultaneous equations, find the number of each kind of box.
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
⇒ x= 14

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.
