Answer:
A, 120 degrees
Step-by-step explanation:
=============================================================
Explanation:
Triangle ABC is equilateral, so all three sides are the same length. This means the three angles are also the same measure. Call each interior angle x.
The three angles add to 180, so x+x+x = 180 solves to x = 60. Each interior angle is 60 degrees.
Angle DAC is an exterior angle of measure 180-x = 180-60 = 120 degrees
------------
Or another method you could use is the fact that all exterior angles of any polygon add to 360.
Since we have n = 3 sides, this means each exterior angle of an equilateral triangle is 360/n = 360/3 = 120 degrees
We consider this a regular polygon because all sides are the same length and all angles are the same measure. So the formula for the exterior angle measure 360/n would apply to any regular polygon and not just triangles.

Given the volume of the cuboid is atleast 150cm3 and the surface area of the cuboid is less than 320cm2. Determine all the possible values of x by solving simultaneous inequalities.
Answers
Answer:
Step-by-step explanation:
To solve this problem, we can start by finding the possible range of values for the volume of the cuboid, which is at least 150 cm^3. The volume of a cuboid is given by the formula V = lwh, where l is the length, w is the width, and h is the height. Since the volume is at least 150 cm^3, we can set up the following inequality:
V >= 150
lwh >= 150
Next, we can find the possible range of values for the surface area of the cuboid, which is less than 320 cm^2. The surface area of a cuboid is given by the formula A = 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height. Since the surface area is less than 320 cm^2, we can set up the following inequality:
A < 320
2lw + 2lh + 2wh < 320
Now, we can solve these simultaneous inequalities to find the possible values of x, which represent the lengths, widths, and heights of the cuboid. To do this, we can start by finding the possible values of l, w, and h that satisfy both inequalities.
One way to do this is to rewrite the inequalities in terms of a single variable, such as l, and then solve for the possible values of l that satisfy both inequalities. For example, we could substitute the expression for the volume (lwh) and the expression for the surface area (2lw + 2lh + 2wh) into the inequality for the volume (V >= 150) and the inequality for the surface area (A < 320), respectively, and then solve for the possible values of l that satisfy both inequalities.
I hope this helps! Let me know if you have any questions or need further assistance.
The surface area of a cuboid is given by the formula A = 2lw + 2lh + 2wh, where A is the surface area and l, w, and h are the dimensions of the cuboid as described above.
We can use these formulas to write two inequalities:
V = l * w * h >= 150
A = 2lw + 2lh + 2wh < 320
To solve this system of inequalities, we can begin by substituting the expression for V into the second inequality:
2lw + 2lh + 2wh < 320
l * w * h >= 150
Next, we can divide both sides of the second inequality by l * w * h to find an expression for h in terms of l and w:
h < 320 / (l * w)
h >= 150 / (l * w)
Since h must be greater than or equal to 150 / (l * w) and less than 320 / (l * w), we can find all possible values of h by finding the values of l and w that satisfy these inequalities.
To find the values of l and w that satisfy these inequalities, we can begin by substituting the expression for h into the first inequality:
2lw + 2l(150 / (l * w)) + 2w(150 / (l * w)) < 320
3lw + 300 < 320
lw < 20
Since lw must be less than 20, we can find all possible values of l and w by listing all pairs of values that satisfy this inequality. Some possible pairs of values are (1, 20), (2, 10), (4, 5), and so on.
We can then use these values of l and w to find the corresponding values of h using the expression h = 150 / (l * w). For example, if l = 1 and w = 20, then h = 150 / (1 * 20) = 7.5. If l = 2 and w = 10, then h = 150 / (2 * 10) = 15. If l = 4 and w = 5, then h = 150 / (4 * 5) = 7.5.
Therefore, all possible values of x (which represents the length, width, and height of the cuboid) are:
(1, 20, 7.5)
(2, 10, 15)
(4, 5, 7.5)
and so on…
How do I create an equation and solve for x
Answers
Answer:
Equation: (2x + 30) + 106 = 180
x = 22°
Step-by-step explanation:
We know that the missing angle from within the triangle and the expression 2x + 30 makes 180 so we can say;
180 - (33 + 41) = missing angle
180 - 74 = missing angle
106° = missing angle
Now we can set up our equation to solve for x:
(2x + 30) + missing angle = 180°
(2x + 30) + 106 = 180° => This would be our equation:
Now let's solve:
2x + 30 + 106 = 180°
2x + 136 = 180
2x = 180 - 136
2x = 44
x = 44/2
x = 22°
Hope this helps!
Answer:
x = 22
Step-by-step explanation:
To solve this the first thing you would need to do is solve the angle that is unmarked in the triangle. To do this you would use the knowledge that the interior agnles of triangles alwasy equal to 180 degrees.
In this case, you would add 33 + 41 = 74 and then you would
subtract 180 - 74 = 106
The next step would be to find the question mark 2x + 30 = ?
To do this you would have to use the 106 degrees from the previous step.
Knowing that (2x + 30) + 106 = 180 degrees this should be easy to solve.
(the angles on either side of a line that is split always add to equal 180 degrees)
You would then subtract 180 - 106 = 74
Now we know that 2x + 30 = 74
Now you would subtract 30 fom both sides to find that 2x = 44
All you have to do now is divide each side by to find that x = 22

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
Answers
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)

(will give brainliest if correct)
Answers
Answer: B
The best type of graph to show changes over time is a line graph. A line graph is ideal for displaying trends and variations in data over a continuous period. It consists of a series of data points connected by line segments, allowing for a clear visualization of how values change over time. Bar graphs, histograms, and circle graphs are better suited for other types of data analysis, such as comparing categories or showing proportions.

The length of an island is changing at the rate of –17 inches per year. How long will it take for the change in the length of the island to be –255 inches?
Answers
Answer:
15 years
Step-by-step explanation:
-255/-17=15
Based on the future dates concept, and the available content of the question, it will take 15 years for the change in length of the island to be -255 inches.
What is the Future date?Future date is a term that is used to describe the major activities of a certain place or humans.
In this case, the time it takes for the change in length to be -255 inches we can set up the following equation:
Change in length = rate * time
-255 inches = -17 inches/year * time
To solve for time divide both sides of the equation by -17 inches/year:
time = -255 inches / (-17 inches/year)
Simplifying the expression:
time = 15 years
Therefore, in this case, it is concluded that it will take 15 years for the change in length of the island to be -255 inches.
