Each blade on a windmill is in the shape of a triangle with a base of 7 feet and a height of 4 feet if there are four blades on the WinMail what is the total area of the blades
Given is the shape of a triangle with base = 7 feet and height = 4 feet.
We know the formula for area of triangle is given as follows :-
[tex] Area\; of\; Triangle=\frac{1}{2} *(Base)*(Height) \\\\
Area = \frac{1}{2} (7)(4) \\\\
Area = \frac{28}{2} \\\\
Area = 14 \;squared \;feet [/tex]
So, the area of a blade is 14 squared feet.
There are four blades on wind mill. Then area of all four blades would be 4 times 14.
Hence, total area of all four blades = 4 x 14 = 56 squared feet.
The total area of the four windmill blades, each with a base of 7 feet and a height of 4 feet, is 56 square feet.
The question involves calculating the total area of windmill blades, each shaped as a triangle. To find the area of a single blade, we use the formula for the area of a triangle, which is (base x height) / 2. For a blade with a base of 7 feet and a height of 4 feet, the area of one blade is:
Area = (7 ft x 4 ft) / 2 = 28 ft² / 2 = 14 ft²
Since there are four blades on the windmill, the total area of the blades can be calculated by multiplying the area of one blade by the number of blades:
Total area = 14 ft2 x 4 = 56 ft²

The sides of a triangle are 7, 4, n. If n is an integer, state the largest and smallest possible values of n.
smallest value is-
largest value is-
Answer:
11 > n > 4
Step-by-step explanation:
Given any two sides of a triangle, we now that the sum of such sides MUST be greater than the measure of the remaining side. This is, given the three sides a, b and c, it must be that:
a + b > c
a + c > b
b + c > a
For our case:
7 + 4 > n (1) ---> 11>n
7 + n > 4 (2)
4 + n > 7 (3)
The 1 inequality says that the n side MUST be less than 11.
Now, pick the (3) inequality and subtract 4 in both sides:
4 + n -4 > 7 - 4
n > 3
So, the n side must be grater than 3.
Thus, the solution is:
11 > n > 3
As we are working with integers we now that the grater integer larger than 3 is 4, and the greater integer less than 11 is 10. So, the side must be equal or greater to 4 and equal or less than 10:
10 >= n >= 4

Describe the relationship between the area of a parallelogram and the area of a triangle that have the same base and height.
If we have a parallelogram and a triangle with the same base and height, the area of the parallelogram will be exactly twice the area of the triangle. This can be expressed as:
[tex]\[ A_{\text{parallelogram}} = 2 \times A_{\text{triangle}} \][/tex]
The area of a parallelogram is twice the area of a triangle that has the same base and height.
To understand the relationship between the area of a parallelogram and the area of a triangle with the same base and height, we can start by recalling the formulas for the area of each shape.
The area [tex]\( A \)[/tex] of a triangle with base[tex]\( b \)[/tex] and height [tex]\( h \)[/tex] is given by the formula:
[tex]\[ A_{\text{triangle}} = \frac{1}{2} \times b \times h \][/tex]
The area [tex]\( A \)[/tex] of a parallelogram with the same base [tex]\( b \)[/tex] and height [tex]\( h \)[/tex] is given by the formula:
[tex]\[ A_{\text{parallelogram}} = b \times h \][/tex]
From these formulas, we can see that the area of a parallelogram is the full rectangle formed by the base and height, while the area of a triangle is half of that rectangle (since a triangle is essentially half of a parallelogram with the same base and height).

A. 85 minutes
B. 76.5 minutes
C. 8.5 minutes
D. 7.65 minutes
Answer:
25.5÷3=8.5
answer is 8.5....
Answer: C 8.5
Step-by-step explanation:
We can use the formula:
time = (number of revolutions) / (rate of revolution)
Substituting the given values, we get:
time = 25.5 / 3
time = 8.5
Therefore, the Carousel will take 8.5 minutes to spin 25.5 times.

The ratio of Paul’s age to Luis’s age is 2:3. The sum of their ages is 35 years. Find the age of each one.
PLZ HELP AND SHOW WORK :)
To find Paul and Luis's ages, the ratio 2:3 is translated to 2x and 3x, and with the sum of their ages being 35 years, we solve the equation to find x = 7. Therefore, Paul is 14 years old and Luis is 21 years old.
Explanation:The question involves finding the ages of Paul and Luis given that the ratio of their ages is 2:3 and the sum of their ages is 35 years. To solve this, let's denote Paul's age as 2x and Luis's age as 3x, where x is a common multiplier. The equation based on the sum of their ages will then be:
2x + 3x = 35
Solving this equation, we combine like terms:
5x = 35
Now, divide both sides by 5 to find the value of x:
x = 35 / 5
x = 7
So, Paul's age is 2x which is 2 * 7 = 14 years, and Luis's age is 3x which is 3 * 7 = 21 years.

a company sells snack bags that contain a mixture of almonds and walnuts. there are 15 almonds per bag and 9 walnuts per bag. if x represents the number of snack bags the company sells, which of the following equations can be used to find the total number of nuts needed to fill the snack bags?
Answer:
y = 21x
Step-by-step explanation:
12x for the almonds
9x for the walnuts
12x + 9x is:
21x total
So, the formula should be:
y = 21x
Final answer:
The equation is Total nuts = 24 nuts per bag * x bags.
Explanation:
To find the total number of nuts needed to fill the snack bags the company sells, we need to calculate the sum of almonds and walnuts in each bag and then multiply that by the number of snack bags sold (represented by x).
Each snack bag contains:
15 almonds9 walnutsThe total number of nuts per bag is:
15 almonds + 9 walnuts = 24 nuts per bag
Thus, if x represents the number of snack bags sold, the equation to find the total number of nuts required is:
Total nuts = 24 nuts per bag * x bags

The equation of a line passing through points (-2, -2) and (2, 2) is y = x.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, a line that passes through the points (-2, -2) and (2, 2).
So, the slope of the line is (y₂ - y₁)/(x₂ - x₁).
= (2 + 2)/(2 + 2).
= 4/4.
= 1.
Equation of a line in point-slope form is y - y₁ = m(x - x₁).
y + 2 = 1.(x + 2).
y + 2 = x + 2.
y = x.

What is the relative maximum and minimum of the function? f(x) = 2x2 + 28x - 8
Answer:
Minimum: y=-106. Maximum: infinite
Step-by-step explanation:
The function described is a parabola, written in the form:
[tex]f(x)=ax^2 +bx+c[/tex]
with:
[tex]a=2\\b=28\\c=-8[/tex]
First of all, we notice that the parabola is upward, because the sign of the coefficient of the second-order term (a) is positive (in fact, a=2). Therefore, it has a minimum value of y. The x corresponding to the vertex of the parabola is given by:
[tex]x_v=-\frac{b}{2a}=-\frac{28}{2\cdot 2}=-7[/tex]
And substituting into f(x), we find the minimum value of y:
[tex]f(-7)=2(-7)^2+28(-7)-8=98-196-8=-106[/tex]
While the parabola has no maximum value, since it goes to infinite as x becomes larger.
Consider the statement below. More than 20 students participated in a drawing competition. Which number line best represents the statement?
Answer:
The number line that best represents this statement is:
Option: A
Step-by-step explanation:
We are given a statement that:
More than 20 students participated in a drawing competition.
This means that when this statement is represented on the number line the region that is covered is:
(20,∞)
Since the more than 20 students means that 20 is not included and all the numbers greater than 20 are included.
Also, on the number line the shaded region lie to the right of 20 and there is a open circle at 20 as 20 is not included in the domain.
Hence, option: A is the correct answer.

Bag Two has 6 red balls and 7 blue balls.
Complete the tree diagram:
Answer:
A. 7/13 B. 9 C. 13 D. 7/13 E. 5/14 F. 6/13 G. Red
Step-by-step explanation:
First we take a ball from bag one, there are 14 balls, 5 red, 9 blue, then, there is 5/14 for red and 9/14 for blue.
Then we take a ball from the second bag and we have 13 balls: 7blue and 6 red, so the posibilities are 7/13 for blue and 6/13 for red.
As it doesn't says anything about mixing balls of both bags, it does not matter the result of the first bag for the probabilities in the second one.
