Maggie cut out 4 right triangles of equal size from construction paper. Each right triangle has a base of 6 inches and a height of 8 inches. What is the total area, in square inches, of all the triangles combined?
Answers
Answer:
24
Step-by-step explanation:
First you multiply 6 and 8 then you divide by 2 to get 24
The total area of all the triangles combined is 96 square inches.
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbolΔ.
The area of a right triangle is found by multiplying the base by the height and dividing by 2.
Since each triangle has a base of 6 inches and a height of 8 inches, the area of each triangle is (6 x 8) / 2 = 24 square inches.
Since Maggie cut out 4 triangles of the same size, the total area of all the triangles combined is 4 x 24 = 96 square inches.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Answers
Answer:
Length: 6
Width: 5
Step-by-step explanation:
Givens:
Let L=length and w=width
Area= 30 = Lw
Perimeter = 22 = L + L + w + w= 2L + 2w
L= w+1
Plug in the values into the equation for the perimeter
22= 2L+ 2w
22= 2(w+1)+ 2w
22=2w+2+2w
22=4w+2
20=4w
5=w
Plug w into the equation for L
L=w+1
L=6
We don't have to use the formula for area in this question.
Basically, for any method you need to know the equation for Area and for Perimeter (I will be using • to represent multiplication):
Area(A) = L•W
Perimeter(P) = L + L + W + W
You can also think of perimeter as
P = 2L + 2W
Since we know that the length of the rectangle needs to be 1 unit longer than the width, you basically need to find 2 numbers with a difference of 1 that multiply together to get 30 and that can be multiplied by 2 and added together to get 22. If you look at a multiplication chart you will see that 6 and 5 are 1 unit apart and multiply to get 30. Also, 6•2=12 and 5•2=10. If you add 12 + 10 you get 22. Therefore, your solution would be:
L = 6
W = 5
Like I said I’m happy to assist you further if you want to know how to solve it using more complex equations, which will be necessary on more advanced problems. Just let me know if you want me to! Hope this helped good luck!

The median(middle) is 90
The range(difference between lowest and highest)is 35
The mode is 95, since it popped up 4 times
Answer:
mean = 85.5
median = 90
mode = 95
range = 35
Step-by-step explanation:
First arrange the data in ascending order:
60 75 75 90 90 95 95 95 95
Mean is the average number found by adding all of the numbers together and dividing by the number of terms in the set.
\( = \frac{60 + 75 + 75 + 90 + 90 + 95 + 95 + 95 + 95}{9} \)
\( = \frac{770}{9} \)
=85.5
Median is the middle number of the set: (9+1) ÷2 = 5th term.
60 75 75 90 90 95 95 95 95
therefore the median is 90
The mode is the number that is repeated more often than any other, so 95 is the mode.
The range = the largest value - the smallest value
= L-S = 95-50
= 35
Therefore the range is 35.
If f(x) = x2 and g(x) = 3x - 1 find [ gºf(x)
Answers
Answer:
gºf(x) = \(3x^2 -1\)
Step-by-step explanation:
Given
f(x) = x2
g(x) = 3x - 1
To find
gºf(x)
To find gºf(x) we will use value of f(x) = \(x^2\) in place of in g(x)
lets do that
g(x) = 3x - 1
gºf(x) = 3(f(x)) -1
gºf(x) = \(3x^2 -1\)
Thus, value of gºf(x) is \(3x^2 -1\).

What is the slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) ? (−16,−18)? Write your answer in the simplest form.
Answers
The slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) is to be considered as the 1.2.
Calculation of the slope of the line:here we used the following formula
So,
\(= y_2-y_1\div x_2-x_1\)
So,
-18-6=-24
And,
-16-4=-20
Now
\(= -24\div -20\)
= 1.2
Hence, The slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) is to be considered as the 1.2.

The slope of the line that passes through the points (4, 6) and (-16, -18) is; 6/5.
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line. Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.
\(m = \dfrac{y-q}{x-p}\)
Given that the line that passes through the points (4, 6) and (-16, -18)
WE need to find the slope of the line.
Since, \(m = \dfrac{y-q}{x-p}\)
Therefore, m = -18 - 6 / -16 - 4
m = 24 / -20
m = 6/5
Hence, The slope of the line that passes through the points (4, 6) and (-16, -18) is; 6/5.

A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
