What is the perimeter of the triangle?
Answers
Answer:
The answer is 36
Step-by-step explanation:
First, suppose that each square is the unit length, and from it the length of the hall can be calculated and we find that it is equal to 10, then to find the value of the other two we drop a column of the vertex of the triangle on the base and find that its length is 12 units and it divides the base into two equal halves, so we determine that each side equals 13 units using Pythagoras and it will be The lengths of the sides of the triangle are 10, 13, 13
Then the perimeter is
[tex]10 + 13 + 13 = 36[/tex]

Answer: Median 38 / Mean 24.5
Step-by-step explanation:
The median is 38
and
The mean is 24.5
To find the median just find the number in the middle of an odd set
but if it happens to be an even number add the 2 middle numbers together and divide them by 2
To find the Mean add all of the numbers and divide them by the number of sets ( in this instance its 4 )
3 teas and 2 coffees have a total cost of £7.80.
5 teas and 4 coffees have a total cost of £14.20.
Work out the cost of one tea and the cost of one coffee.
Answers
Answer:
coffee is £1.80 per cup and tea is £1.40 per cup
Step by Step:
The question can be written algebraically, as:(a) 3t + 2c = 7.80(b) 5t + 4c = 14.20To work out the individual costs, we need to make one of the sets of variables equal. We can do this by multiplying the equation (a), giving (c):(a) 6t + 4c = 15.60(c) 5t + 4c = 14.20We can then subtract (c) from (a), giving:t = 1.40T can then be substituted into the initial equation (a), to work out the value of c:(3 x 1.40) +2c = 7.804.20 +2c = 7.802c = 3.60c = 1.80Finally we can check these values by substituting into (b):(5 x 1.40) + (4 x 1.80) = 7 + 7.2 = 14.20Then make sure to show your answers clearly, with units:coffee is £1.80 per cup and tea is £1.40 per cup

Consider the quadratic expression given below.
4x^2 + 8x - 60
Factor the following expression completely.
Answers
Answer:
4(x + 5)(x - 3)
Step-by-step explanation:
Given
4x² + 8x - 60 ← factor out 4 from each term
= 4(x² + 2x - 15) ← factor the quadratic
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)
The factors are + 5 and - 3 , since
+ 5 × - 3 = - 15 and + 5 - 3 = + 2, then
x² + 2x - 15 = (x + 5)(x - 3)
Then
4x² + 8x - 60 = 4(x + 5)(x - 3) ← in factored form

A horizontal line includes the points (0, -2) and (3, -2). Find the slope of the line.
wil give BRAINLIEST
pls answer correctly
Answers
Answer:
We conclude that the slope of the line containing the points (0, -2) and (3, -2) is:
[tex]m = 0[/tex]Step-by-step explanation:
Given that the line includes the points
(0, -2)(3, -2)We need to find the slope of the line containing the points between (0, -2) and (3, -2) using the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope between (x₁, y₁) and (x₂, y₂)
In our case,
(x₁, y₁) = (0, -2)(x₂, y₂) = (3, -2)now substituting (x₁, y₁) = (0, -2) and (x₂, y₂) = (3, -2) in the slope formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{-2-\left(-2\right)}{3-0}[/tex]
[tex]m=\frac{-2+2}{3}[/tex]
[tex]m=\frac{0}{3}[/tex]
[tex]m = 0[/tex]
Therefore, we conclude that the slope of the line containing the points (0, -2) and (3, -2) is:
