The given equation is
5x + 3y = 15
The points to be plotted of on the graph are
(3, 0)
(0, 5)
The graph is shown below
To rewrite as slope intercept equation, it becomes
3y = 15 - 5x
Dividing both sides by 3, we have
y = 3 - 5x/3
y = - 5x/3 + 3

Tower one, a cube with a hexagonal prism measures 15.6cm. Tower two, a cube with a cylinder measures 18.3cm. Tower 3, a hexagonal prism with a cylinder measures 13.9cm. What is the height of the 4th tower when all three shapes are used?
Answers
Answer:
\(Tower 4 = 23.9cm\)
Step-by-step explanation:
Given
Tower one = 15.6 cm
Tower two = 18.3 cm
Tower 3 = 13.9 cm.
Required:
Height of the 4th tower
Represent a cube by X; a cylinder by Y and a hexagonal prism by Z
Tower one, a cube with a hexagonal prism = X + Z = 15.6
Tower two, a cube with a cylinder = X + Y = 18.3
Tower 3, a hexagonal prism with a cylinder = Z + Y = 13.9
\(X + Z = 15.6\) ----- Equation 1
\(X + Y = 18.3\) ----- Equation 2
\(Z + Y = 13.9\) ----- Equation 3
Subtract equation 1 from 2
\((X + Y = 18.3) - (X + Z = 15.6)\)
\(X - X + Y - Z = 18.3 -15.6\)
\(Y - Z = 18.3 -15.6\)
\(Y - Z = 2.7\) ---- Equation 4
Add Equation 4 to Equation 3
\((Y - Z = 2.7) + (Z + Y = 13.9)\)
\(Y + Y - Z + Z = 2.7+ 13.9\)
\(2Y = 2.7+ 13.9\)
\(2Y = 16.6\)
Divide both sides by 2
\(\frac{2Y}{2} = \frac{16.6}{2}\)
\(Y = \frac{16.6}{2}\)
\(Y = 8.3cm\)
Substitute \(Y = 8.3cm\) in Equation 2 and 3
\(X + Y = 18.3\) ----- Equation 2
\(X + 8.3 = 18.3\)
Subtract 8.3 from both sides
\(X + 8.3 - 8.3 = 18.3 - 8.3\)
\(X = 18.3 - 8.3\)
\(X = 10cm\)
\(Z + Y = 13.9\) ----- Equation 3
\(Z + 8.3 = 13.9\)
Subtract 8.3 from both sides
\(Z + 8.3 - 8.3 = 13.9 - 8.3\)
\(Z = 13.9 - 8.3\)
\(Z = 5.6cm\)
So, we have that
\(X = 10cm\)
\(Y = 8.3cm\)
\(Z = 5.6cm\)
The question states that the 4th tower is made up of the three shapes;
This implies that;
\(Tower 4 = X + Y + Z\)
\(Tower 4 = 10cm + 8.3cm + 5.6cm\)
\(Tower 4 = 23.9cm\)
The height of the 4th tower is 23.9cm

Calculate the side lengths a and b to two decimal places
Answers
Answer:
E
Step-by-step explanation:
using the Sine rule in Δ ABC
\(\frac{a}{sinA}\) = \(\frac{b}{sinB}\) = \(\frac{c}{sinC}\)
where a is the side opposite ∠ A , b opposite ∠ B , c opposite ∠ C
we require to calculate ∠ C
∠ C = 180° - (64 + 85)° = 180° - 149° = 31°
then to find a , using
\(\frac{a}{sinA}\) = \(\frac{c}{sinC}\)
\(\frac{a}{sin64}\) = \(\frac{9.3}{sin31}\) ( cross- multiply )
a × sin31° = 9.3 × sin64° ( divide both sides by sin31° )
a = \(\frac{9.3sin64}{sin31}\) ≈ 16.23 ( to 2 decimal places )
then to find b , using
\(\frac{b}{sinB}\) = \(\frac{c}{sinC}\)
\(\frac{b}{sin85}\) = \(\frac{9.3}{sin31}\) ( cross- multiply )
b × sin31° = 9.3 × sin85° ( divide both sides by sin31° )
b = \(\frac{9.3sin85}{sin31}\) ≈ 17.99 ( to 2 decimal places )

As a result, 68% of the data falls into the range of values between -1 and 1, which is one standard deviation from the mean. The closest estimate of the solution is 68%.
What is equation?A mathematical equation is a formula that connects two claims and uses the equals symbol (=) to denote equivalence. An equation in algebra is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign places a space between the variables 3x + 5 and 14. The relationship between the two sentences that are written on each side of a letter may be understood using a mathematical formula. The symbol and the single variable are frequently the same. as in, 2x - 4 equals 2, for instance.
For a normally distributed data set with a mean of 0 and a standard deviation of 0.5, the proportion of values between -1 and 1 is most closely related to 68%.
Approximately 68% of the data in a normal distribution lies within one standard deviation of the mean, which explains why. One standard deviation below the mean is -0.5, and one standard deviation above the mean is 0.5 since the mean is 0 and the standard deviation is 0.5. As a result, 68% of the data falls into the range of values between -1 and 1, which is one standard deviation from the mean. The closest estimate of the solution is 68%.

For two n by n square matricies A and B,
suppose rankA = rankB = n-1.
Can rank(AB) become less than n-1 ?
(e.g. rank (AB) = n-2)
If so, I humbly ask you for an example.
Thank you very much.
Answers
No, the rank of the product of two n by n square matrices A and B, denoted as AB, cannot be less than n-1 if both A and B have ranks of n-1.
According to the Rank-Nullity theorem, for any matrix M, the sum of its rank and nullity is equal to the number of columns in M. In this case, the number of columns in AB is n, so the sum of the rank and nullity of AB must be n.
If rank(A) = rank(B) = n-1, it means that both A and B have nullity 1. The nullity of a matrix is the dimension of its null space, which consists of all vectors that get mapped to the zero vector when multiplied by the matrix. Since both A and B have rank n-1, their null spaces consist only of the zero vector.
Now, considering AB, if the rank of AB were less than n-1, it would mean that the nullity of AB is greater than 1.
However, this would violate the Rank-Nullity theorem since the sum of the rank and nullity of AB must be n, which is the number of columns.
Therefore, if rank(A) = rank(B) = n-1, the rank of AB cannot be less than n-1.

In the diagram , DE is a midsegment of triangle ABC.
And, The area of triangle ABC is 96 square units
Now, We know that,
Since DE is a midsegment of triangle ABC, it is parallel to AB and half the length of AB. Therefore, DE is half the length of AB.

The bar diagram represents the ratio of points scored by the home team and the visiting team in a basket ball game. How many points did the visiting team score if the home team scored 84 points?
Answers
Answer:
60 points.
Step-by-step explanation:
Bar diagram which represents the ratio of the points earned by the home team and visitor's team.
Fro the bar diagram,
Ratio of the points earned = \(\frac{\text{Points earned by the home team}}{\text{Points earned by visitor's team}}\)
= \(\frac{7}{5}\)
If the points earned by the home team = 84
\(\frac{\text{Points earned by the home team}}{\text{Points earned by visitor's team}}\) = \(\frac{7}{5}\)
\(\frac{84}{\text{Points earned by visitor's team}}\) = \(\frac{7}{5}\)
Points earned by the visitor's team = \(\frac{84\times 5}{7}\)
= 60
Therefore, 60 points were earned by the visitor's team.
Two 8-foot-long 2 × 4s are cut into sections of equal length. Board A is cut into 9 equal sections, of which 5 are used. Therefore, of the board has been used; of it remains. Board B is cut into 7 equal sections, of which 4 are used. That means of the board has been used; of it remains. Which has the longest remaining section, Board A or Board B?
Answers
Answer:
Board A
Step-by-step explanation:
Since the boards were split into equal sections, we can think of them as fractions.
\(\frac{5}{9}\) of Board A was used, meaning \(\frac{4}{9}\) of Board A remains.
\(\frac{4}{7}\) of Board B was used, meaning \(\frac{3}{7}\) of Board B remains.
To give these fractions common denominators, we multiply the numerator and denominator by the opposite denominator.
4/9 * 7/7 = 28/63
3/7 * 9/9 = 27/63
28/63 is greater than 27/63. This means that Board A has the longest remaining section.
Board A has the longest portion remaining section.
What is the Ratio?A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other
Two 8-foot-long 2 × 4s are cut into sections of equal length. Board A is cut into 9 equal sections, of which 5 are used.
To determine the longest remaining section, Board A or Board B
The boards can be considered as ratios since they have been divided into equal portions.
5/9 of Board A was used, while Board A's significance is still unchanged.
4/7 of Board B was used, while Board B's significance is still unchanged.
We multiply the numerator and denominator by the opposing denominator to give these ratios common denominators.
⇒ 4/9 * 7/7 = 28/63
⇒ 3/7 * 9/9 = 27/63
So 27/63 is greater than 28/63.
This indicates that Board A has the longest portion remaining section.
