Answer:
294 m² is correct
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A = [tex]\frac{1}{2}[/tex] h (a + b)
where h is the height and a, b the parallel bases
here h = 21, a = 21 and b = 7, thus
A = [tex]\frac{1}{2}[/tex] × 21 × 28 = 294 m²

Given the following graph, would the point (1,2) Be a solution of the inequality? Explain.
ANSWER
The point (1,2) is not a solution
EXPLANATION
We could see that, the point (1,2) lies exactly on the boundary line.
Since the boundary line is dashed, the points on the boundary line are not solution.
Alternatively:
We deduce the inequality from the graph to be;
[tex]y < 3x - 1[/tex]
If the point (1,2) is a solution,then it must satisfy the inequality.
[tex]2 \: < \: 3(1) - 1[/tex]
[tex]2 \: < \: 2[/tex]
This statement is false.
Hence, the point (1,2) is not a solution.
how much more is 1.8 • 10^11 greater than 7.2 • 10^10
Answer:
1.8.10=1.80000000000
7.2.10=7.2000000000
Step-by-step explanation:
[tex]To find out how much 1.8 * 10^11 is greater than 7.2 * 10^10, you can subtract the two values:(1.8 * 10^11) - (7.2 * 10^10)To simplify this expression, you need to have the exponents match. You can do this by rewriting 7.2 * 10^10 as 0.72 * 10^11:(1.8 * 10^11) - (0.72 * 10^11)Now, subtract the coefficients:(1.8 - 0.72) * 10^11Calculate the subtraction:1.08 * 10^11So, 1.8 * 10^11 is 1.08 * 10^11 greater than 7.2 * 10^10[/tex]

When you join the midpoints of two sides of a triangle, two properties are true.
The Line segment you have drawn is parallel to the third side.The Line segment you have drawn is 1/2 the size of the third side.For this question, the first property is not as important as the second.
it means that DE is 1/2 the size of GJ
Equation
4x + 5 = 1/2 * (3x + 25)
Solution
Multiply both sides by 2
2(4x + 5) = 2*[1/2*(3x + 25) Simplify
2(4x + 5) = 3x + 25 Remove the brackets on the left
8x + 10 = 3x + 25 Subtract 3x from both sides
8x-3x + 10 = 25 Subtract 10 from both sides.
5x = 25 - 10
5x = 15

The total cost of a suit and a coat is
$291. The coat cost twice as much as
the suit. How much did the coat cost?
The coat costs $194 while the suit costs $97
To find out how much the coat costs when a suit and a coat together cost $291 and the coat costs twice as much as the suit, we use algebra to deduce that the suit costs $97 and the coat costs $194.
To solve the problem of determining how much the coat costs when the total cost of a coat and a suit is $291, and the coat costs twice as much as the suit, we can set up a system of equations. Let's define s as the cost of the suit and c as the cost of the coat. Following the given information, we have two equations:
s + c = $291 (the total cost of the suit and the coat)c = 2s (the coat costs twice as much as the suit)Substituting the second equation into the first one gives us:
s + 2s = $291
Combining like terms, we get:
3s = $291
Dividing both sides by 3 to solve for s, we find:
s = $97
Now that we have the cost of the suit, we can use the second equation to find the cost of the coat:
c = 2s = 2 times $97 = $194
Therefore, the coat costs $194.
You want to make a rectangular box, open at the top, by cutting the same size square corners out of a rectangular sheet of cardboard and then folding up the sides. The cardboard measures 11 in. by 14 in. What are the dimensions of the box that will have greatest volume if the possible corner cuts measure 1 in., 2 in., 3 in., or 4 in.?
Answer:
2 in.
Step-by-step explanation:
If we cut squares from all 4 corners and make it into a open rectangular box, the length of the square cut will become the height of the rectangular prism.
If we cut 1 inch side square:
The 11 inch side will become 11 - 2(1) = 9 and 14 inch side will become 14 - 2(1) = 12. Height is 1. So Volume would be 9 * 12 * 1 = 108
If we cut 2 inch side square:
The 11 inch side will become 11 - 2(2) = 7 and 14 inch side will become 14 - 2(2) = 10. Height is 2. So Volume would be 7 * 10 * 2 = 140
If we cut 3 inch side square:
The 11 inch side will become 11 - 2(3) = 5 and 14 inch side will become 14 - 2(3) = 8. Height is 3. So Volume would be 5 * 8 * 3 = 120
If we cut 4 inch side square:
The 11 inch side will become 11 - 2(4) = 3 and 14 inch side will become 14 - 2(4) = 6. Height is 4. So Volume would be 3 * 6 * 4 = 72
Hence, the greatest volume is when we cut 2 inch side square.

Step-by-step explanation:
find the solutions to the equation by compelting the square x^2-6x=7
Answer:
The solution set is {-1, 7}
Step-by-step explanation:
Rewrite x^2-6x=7 as x^2 - 6x = 7.
Identify the coefficient of the x term; it is -6.
Halve this coeff (obtaining -3)
Square this result (obtaining 9)
Add 9 to x^2 - 6x and then subtract 9 from the result: x^2 - 6x + 9 - 9
Then we have:
x^2 - 6x + 9 - 9 = 7. Add 9 to both sides, obtaining
x^2 - 6x + 9 = 16
Rewrite x^2 - 6x + 9 as the square of a binomial: (x - 3)^2
Then we have
(x - 3)^2 = 16
Taking the square root of both sides, we get
x - 3 = ±4, so that: x = 3 + 4 = 7, and x = 3 - 4 = -1.
The solution set is {-1, 7}.
Answer:
To complete the square x^2-6x=7
We take the coefficient of X which is -6
divide it by 2 -3
square that number 9
then add it to both sides of the equation.
x^2 -6x + 9 = 16
(x -3) * (x -3) = 16
We take the square root of both sides:
a) x-3 = 4
b) x-3 = -4
Therefore, x = 7 and x = -1

Answer:
B) y = -2x + 14
Step-by-step explanation:
Solution: y = -2x + 14. To solve this problem, first determine the slope of your line. Since perpendicular lines have slopes that are opposite reciprocals of each other, we know that the slope is -2. Then plug your slope (-2) and point (4,6) into the equation y = mx + b to solve for b. The resulting value for b is 14.

At the end of August his account earned $11.50 in interest. Will Emilio meet his savings account goal of $1,000 by September 1st?
A
Yes, and he will have $51.70 more than expected.
B
No, and he would still need $51.70.
C
Yes, and he will have $77.30 more than expected.
D
No, and he would still need $77.30.
Answer:
B. He would still need 51.50
Step-by-step explanation:
First I added up all the deposits Emilio made
so: 621.96+83.11+52.89+307.84=1065.8
then i subtract 129 from the total (1065.8)
which equals 936.8 and I add the 11.5 interest.
which equals 948.3 which is 51.70 less than 1000. Therefore, Emilio still need 51.70 in order to meet his saving accounts goal.

Graph the relation shown in the table. Is the relation a function? Why or why not?
A; No; a vertical line passes through two graphed points.
B; Yes; no horizontal line passes through two graphed points.
C; No; a horizontal line passes through two graphed points.
D; Yes; no vertical line passes through two graphed points.
Answer: D; Yes; no vertical line passes through two graphed points.
Step-by-step explanation:
A graph is only considered a function if it passes the vertical line test. The vertical line test is basically when you put a vertical line on any point in the graph, it can’t pass through more than one graphed point. It can only touch the line once. That graph is considered a function because no two points touch a vertical line in the same x-value.
Answer:
Option D.
Step-by-step explanation:
A relation is a function if there exist a unique output for each input value. In other words a relation is a function if there exist a unique value of y for each value of x.
Vertical line test : According to the vertical line test if the graph of a relation intersect any vertical line at most once, then the relation is a function.
From the given table it clear that the ordered pairs of relation are(-5,-5), (-3,-3), (1,1) and (2,2).
For each value of x, there is a unique value of y. It means no vertical line passes through two graphed points. So, the given relation is a function.
Therefore, the correct option is D.
the median and mean of these numbers:
8, 14, 13, 12, 14, 15
20 POINTS ANSWER FASTTT
Answer:
Mean : ≈ 12.7
Median: ≈ 13.5
Step-by-step explanation:
To find the mean you must add all the numbers and divide by the # of numbers in the set.
8+12+13+14+14+15 = 76
76/6 ≈ 12.7
To find the median you have to order the numbers from least to greatest, the middle number should be the median, but in this case two numbers are in the middle.
8, 12, 13, 14, 14, 15
So you have to add 14 and 13, which is 27.
Then divide by 2 which is ≈ 13.5
