What is ratio?A ratio in mathematics shows how many times one number is included in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is identical to the ratio 4:3). (i.e., 8:6, which is identical to 4:3). The ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8 (or 3:4). (or 4:7). (or 4:7). A ratio can have any number of values, such as counts of people or things or measures of length, weight, time, etc. In most cases, both numbers must be positive.

Emmett made sand art bottles to sell at his school's craft fair. He wanted to use 9 different colors of sand. So, he bought 1 pound of each color. Then, he filled as many 6-ounce bottles as he could. How many sand art bottles did Emmett make?
The number of bottles will be 24 bottles.
How to calculate the value?It should be noted that 1 pound = 16 ounces.
Since he bought 1 pound of each color, the total pounds will be:
= 1 × 9 = 9 pounds.
The number of sand art will be:
= 9 pounds / 6 ounce
= (9 × 16) / 6
= 24 bottles

Evaluate the expression when x = 5:
10|7−x|
A. -120
B. -20
C. 20
D. 120
Answer:
C. 20
Step-by-step explanation:
10|7−x| here we are asked to find the absolute value.
x is given as 5 so if we just rewrite the expression:
10|7-5| = 20 because absolute value cannot be negative.
The diagram shows a rectangle ABCD.The point A is (2,14) , Bus (-2,8) and C lies on the x-axis.
Find
(i) the equation of BC.
(ii) the coordinates of Cand D.
Using linear function concepts, it is found that:
i) The equation of BC is given by: [tex]y = -\frac{2}{3}x + \frac{20}{3}[/tex].
ii) The coordinates of C are C(0,10) and the coordinate of D are D(14,6).
What is the missing information?The diagram is missing, and is shown in the graph at the end of the answer.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, the coordinates are given as follows:
A(2, 14), B(-2,8) and C(x,0).
From the diagram, AB and BC are perpendicular, meaning that the multiplication of their slopes is of -1.
Given two points, the slope is given by change in y divided by change in x. Hence the slope of AB is given as follows:
mAB = (8 - 14)/(-2 - 2) = 3/2.
The slope of BC is given as follows:
mBC = (0 - 8)/(x - (-2))
mBC = -8/(x + 2).
The multiplication of the slopes is of -1, hence:
mAB x mBC = -1
-12/(x + 2) = -1
- x - 2 = -12
x = 10.
Hence, the slope of BC is:
mBC = -8/(x + 2) = -8/12 = -2/3.
Then:
y = -2/3x + b.
When x = 10, y = 0, hence we can find b as follows:
0 = -2/3(10) + b
b = 20/3.
Hence:
The equation of BC is given by: [tex]y = -\frac{2}{3}x + \frac{20}{3}[/tex].
From the diagram, we also have that AB and CD are parallel, meaning that they have the same slope, hence, considering D(x,y), we have that:
mCD = mAB
y/(x - 10) = 3/2
y = 1.5(x - 10)
y = 1.5x - 15.
AD and BC are also parallel, hence:
mAD = mBC
(y - 14)/(x - 2) = -2/3
Since y = 1.5x - 15, we have that:
(1.5x - 15 - 14)/(x - 2) = -2/3
(1.5x - 29)/(x - 2) = -2/3
3(1.5x - 29) = -2(x - 2)
4.5x - 87 = -2x + 4.
6.5x = 91
x = 91/6.5
x = 14.
y = 1.5x - 15 = 1.5(14) - 15 = 21 - 15 = 6.
Hence:
The coordinates of C are C(0,10) and the coordinate of D are D(14,6).

A polygon is regular if each of its sides has the same length. Find the perimeter of the regular polygon.
Based on the calculations, the perimeter of this regular polygon is equal to 7.5 units.
What is a polygon?A polygon can be defined as a two-dimensional geometric shape that comprises straight line segments and a finite number of sides. Also, some examples of a polygon include the following:
TriangleQuadrilateralPentagonHexagonHeptagonOctagonNonagonHow to determine the perimeter of this regular polygon?Since this polygon is a regular polygon with each of its sides being equal, we have:
3(x - 1) = 5x - 6
3x - 3 = 5x - 6
5x - 3x = 6 - 3
2x = 3
x = 3/2
x = 1.5.
The measure of each of its sides is given by:
3x - 3 = 5x - 6
3(1.5) - 3 = 5(1.5) - 6
4.5 - 3 = 7.5 - 6
1.5 = 1.5
Each side, a = 1.5 units.

a match box has length x cm, width x +1 cm and height 3 cm. express its surface area as a function of x
Answer:
2x² + 14x + 6
Step-by-step explanation:
A match box is in the shape of a right rectangular prism so we can use the formula for the surface area of such a solid
A=2(wl+hl+hw)
where l = length, w=width and h = height
Substituting l = x, w = x+1 and height = 3 we get
wl = x(x + 1) = x² + x
hl = 3x
hw = 3(x + 1) = 3x + 3
So A = 2( x² + x + 3x + 3x + 3)
A = 2(x² + 7x + 3)
A = 2x² + 14x + 6

By using horizontal and vertical translations, we find that the expression for g(x) is g(x) = [tex]\sqrt[5]{x - 2}[/tex] + 1. (Correct choice: C)
What kind of transformations have been done on a parent function to generate another function?
The picture presents us the graphs of two functions. The blue function represents the parent function f(x), whose form is [tex]f(x) = \sqrt[5]{x}[/tex], whereas the black function is the transformed function g(x), which is the result of applying two transformations:
Horizontal translation 2 units in +x direction.Vertical translation a unit in +y direction.Then, we must apply the following definition involving the concepts of horizontal and vertical translations:
g(x) = f(x - 2) + 1 (1)
If we know that [tex]f(x) = \sqrt[5]{x}[/tex], then the complete expression of the function is:
g(x) = [tex]\sqrt[5]{x-2}[/tex] + 1
Hence, by using horizontal and vertical translations, we find that the resulting expression for g(x) is g(x) = [tex]\sqrt[5]{x - 2}[/tex] + 1. (Correct choice: C)

The correct option is Quantity a: the number of prime numbers between 0 and 100, inclusive is greater.
What is a prime number?A prime number is a natural number greater than 1 that is not the sum of two lesser natural numbers (or a prime). Any natural number greater than one that is not prime is referred to as a composite number. For instance, the product 1 5 and 5 1 are the only two ways to write the number 5, making it a prime. The fact that it is the sum of two smaller integers (2 x 2), 4, however, makes it composite. Primes play a significant role in number theory because of the fundamental theorem of arithmetic, it states that any natural number greater than one is either a prime number itself or may be factored as a unique prime product up to the order of the primes. the prime number (or a prime).
The number of primes reduces almost exponentially as we move up the number line. The prime numbers between 0 and 100 are therefore far more numerous than those between 101 and 200. It is crucial to understand this general number theory point, but it may also be rapidly illustrated by attempting to find some primes in these two groups.
