The first side of a triangle is 3cm longer than the second. The third side is twice as long as the second. The perimeter is 31cm. Find the length of each side.
Answer:
7 cm ; 10 cm ; 14 cm
Step-by-step explanation:
x = y + 3
z = 2y
x + y + z = 31
y + 3 + y + 2y = 31
4y = 31 -3
4y = 28
4/4 y = 28/4
y = 7
z = 7(2) = 14
x = 7 + 3 = 10
Let point A be (2,7) and point B be (-6,-3). What point is on the segment connecting A and B such that the distance from the point to B is 4 times the distance from the point to A?
Answer:
The point on the segment connecting A and B that is 4 times as far from B as it is from A is (-8, 8).
Answer:
or the distance to be 4 times the distance from B as A the segment must be divided into (4+1) = 5 segments
so we want the point that is 1/5 of the way from A to B
x from A to B is 2 to - 6 = -8 units 1/5 * -8 + 2 = 0.4
y from A to B is 7 to -3 = -10 units 1/5 * -10 + 7 = 5

A bag contains 10 red marbles, 7 blue marbles, and 3 green marbles. How many blue marbles need to be added to the bag so that the probability of randomly drawing a blue marble is 3/4?.
32 more blue marbles need to be added to the bag so that the probability of randomly drawing a blue marble is 3/4
A bag contains 10 red marbles, 7 blue marbles, and 3 green marbles.
we need to find the numbar of blue marbles need to be added to the bag so that the probability of randomly drawing a blue marble is 3/4
Let the number of blue marbles added be n,
required probability P = 3/4
Total marbles = 10 + 7 + 3
= 20
Number of blue marbles=7
Using definition of probability,
(7 + n)/(20+n) = 3/4
4(7+n)=3(20+n)
28+4n=60+3n
n = 32
Therefore, we need to add 32 more blue marbles to make the probability of randomly drawing a blue marble be 3/4.

Matias has a planter that is full of soil. The planter is a rectangular prism that is 1 1/2 ft high, 3 2/3 ft long, and 2 ft wide. Matias pours all the soil into a new planter. The new planter is a rectangular prism that has a base of 8 1/4. What is the height of the soil in the new planter
The height of the soil in the new planter is 4/3 feet
Consider the old planter
The height of the prism = [tex]1\frac{1}{2}[/tex] feet = 3/2 feet
The length of the prism = [tex]3\frac{2}{3}[/tex] feet = 11/3 feet
The width of the prism = 2 feet
The volume of the rectangular prism = Length × width × height
= 11/3 × 2 × 3/2

The area of the base of the new planter = [tex]8\frac{1}{4}[/tex] square feet = 33/4 square feet
The volume of both planter will be equal
The base area × height = volume

Erin is selling books for $12 each. She wants to make more than $180 in book sales. Write an inequality that can be used to determine the number of books, b, she must sell in order to meet her goal, then solve for b.
The inequality that can be used to determine the number of books, b, Erin must sell in order to meet her goal of making more than $180 in book sales is 12b ≥ 180.
2. The solution to the inequality 12b ≥ 180 is that b ≥ 15.
What is inequality?Inequality is a mathematical statement that two or more mathematical expressions are unequal because their solutions are not equivalent in value.
Inequalities are depicted as less than (<), more than (>), not equal to (≠), less than or equal to (≤), and more than or equal to (≥).
The selling price per book = $12
The total sales revenue expected is ≥ $180
The number of books = b
Inequality describing the situation = 12b ≥ 180
b ≥ 180 ÷ 12
b ≥ 15
Thus, we can conclude that Erin needs to sell 15 or more books to earn $180 or more from the book sales.

How to find number of roots ?According to the Fundamental Theorem of Algebra, a polynomial function of degree n has exactly n roots (also known as zeros).In other words, if f(x) is a polynomial function of degree n, then there exist n values of x, called roots or zeros, that satisfy the equation f(x) = 0.The Fundamental Theorem of Algebra is important because it guarantees the existence of solutions to polynomial equations, which are equations that have the form f(x) = 0, where f(x) is a polynomial function.In this case, the polynomial function is f(x) = 4x^5 - 3x, which is of degree 5. Therefore, the function has exactly 5 roots according to the Fundamental Theorem of Algebra.The correct answer is therefore d) 5 roots.

What is probability?
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
The number of 5 in the table is 4.
The total number of outcomes is 6 × 6 = 36
The number of outcomes of favorable event is 4.
Total number of outcomes is 36.
The probability getting total of 5 after rolling the pair of dice is

The swimming pool was on sale for $1206.2, which is 18.5% less than its initial $1429.35 cost.
What is percent?In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
Here,
Sale price after discount=$1206.2
Discount percent=18.5%
Original price=1206.2+18.5%*1206.2

The graph of the linear function passes through the points (2,44) and (5,80). What is the equation of this function?
y=?x+?
The equation for the given linear function is y = 12m + 20.
What is a linear equation?A linear equation in two variable has the general form as y = ax + by + c, where a, b and c are integers and a, b ≠ 0.
It can be represented as a straight line on a graph.
The given points for the linear function are (2, 44) and (5, 80) respectively.
The slope can be obtained as,
m = (80 - 44)/(5 - 2)
= 36/3
= 12
Substitute the value of m in the general form y = mx + c to obtain,
y = 12x + c
Now, substitute x = 2 and y= 44 in the above expression as,
44 = 12 × 2 + c
=> c = 44 -24
=> c = 20
Thus the linear function can be written in the form of equation as,
y = 12m + 20
Hence, the equation of the function for the given case is y = 12m + 20.
