Answers
Equilateral Triangular Prism
Each side of the triangular face has a length of 196cm
The tent is 250cm long
I have attached an image of the tent. Since the height of the tent is also the height of the triangle, I will solve for the height of the triangle using Pythagorean theorem.
I divided the equilateral triangle into 2 right triangle. The height then becomes the long leg of the triangle. The hypotenuse is 196cm and the short leg is 98cm, half of one side of the triangle.
a² + b² = c²
a² = c² - b²
a² = (196cm)² - (98cm)²
a² = 38,416cm² - 9,604cm²
a² = 28,812cm²
a = √28,812cm²
a = 169.74cm
The height of the tent is 169.74 centimeters.

Describe the graph of the following inequality: 2x - 5y ≤ 6
Answers
To graph the inequality 2x - 5y ≤ 6, plot the line 2x - 5y = 6 with a solid boundary, test a point to determine the solution region, and shade the region that satisfies the inequality, which is below and to the right of the boundary line.
Explanation:To graph the inequality 2x - 5y ≤ 6, you must first draw the boundary line of the inequality. This line is created by graphing the equation 2x - 5y = 6.
Start by finding the intercepts. For the x-intercept, set y to 0 and solve for x, which gives x = 3. For the y-intercept, set x to 0 and solve for y, which gives y = -6/5. These two points can be used to draw the boundary line. Since the inequality is '≤', this line will be solid to show that points on the line satisfy the inequality.
Now you must determine which side of the line contains the solutions to the inequality. You can do this by choosing a test point that is not on the line, like (0,0). Substitute this point into the inequality: 2(0) - 5(0) ≤ 6 is true, so the area containing (0,0), which is below and to the right of the line, is the solution region. Shade this area to show all points that satisfy the inequality 2x - 5y ≤ 6.
15 4/5% of 50
A. .79 B. 79
C. 790 D. 7.9
Answers
"The correct answer is B. 79.
To solve the given problem, we need to calculate 15 4/5 percent of 50. First, let's convert the mixed number to an improper fraction to make the calculation easier.
15 4/5% as a fraction is 15 + 4/5, which can be written as 75/5 + 4/5 = 79/5.
Now, to find the percentage of 50, we multiply 50 by the fraction representing the percentage:
[tex]\[ \frac{79}{5} \times 50 = \frac{79 \times 50}{5} \][/tex]
Next, we simplify the multiplication:
[tex]\[ \frac{79 \times 50}{5} = \frac{3950}{5} \][/tex]
Now, we divide 3950 by 5:
[tex]\[ \frac{3950}{5} = 790 \][/tex]
However, since we are looking for 15 4/5 percent and not 15 4/5 times 50, we need to adjust our calculation by dividing by 100 to get the correct percentage:
[tex]\[ \frac{790}{100} = 79 \][/tex]
Therefore, the final answer is B. 79."
A customer buys an apple pie for $8.04, 6 cloves of garlic for $0./9 each, and a quarts of milk for $1.31. You are working the cash register. The customer gives you a $5 bill, six $1 bills, and a quarter. The register tells you that you ow the customer $0.16 . Round the price of each item to the nearest $0.10 to estimate how much the customer owes.
Answers
The customer gave you 5 + 6 + 0.25 or $11.25, which is very close (and slightly higher) than the total of your estimates. I'd guess the register is correct.
Actual value is $8.04 + 6*0.29 + 1.31 = 8.04 + 1.74 + 1.31 = $11.09. The register is definitely correct.
Final answer:
To estimate the total cost, round each item to the nearest $0.10, sum them up, and subtract from the amount given by the customer. The estimated total cost is $9.80, and the estimated change to be returned is $1.45.
Explanation:
To estimate the total amount the customer owes after rounding to the nearest $0.10, we need to perform the following calculations:
Apple pie: $8.04, rounded to $8.00
6 cloves of garlic: $0.09 each, so $0.09 x 6 = $0.54, rounded to $0.50
Quart of milk: $1.31, rounded to $1.30
The estimated total cost is $8.00 (apple pie) + $0.50 (garlic) + $1.30 (milk) = $9.80.
The customer gives a total of $5 + $6 + $0.25 = $11.25.
Subtracting the estimated total cost from the amount given by the customer:
$11.25 - $9.80 = $1.45, which is the estimated change to be returned to the customer.

How to find the measure of an interior angle of an irregular polygon?
Answers
Exterior Angles of a Polygon Definition: the angle formed by any side of a polygon and the extension of its adjacent side Try this Adjust the polygon below by dragging any orange dot. Click on "make regular" and repeat. Note the behavior of the exterior angles and their sum. Regular polygons In the figure above check "regular". As you can see, for regular polygons all the exterior angles are the same, and like all polygons they add to 360° (see note below). So each exterior angle is 360 divided by the n, the number of sides. As a demonstration of this, drag any vertex towards the center of the polygon. You will see that the angles combine to a full 360° circle. Convex case In the case of convex polygons, where all the vertices point "outwards" away form the interior, the exterior angles are always on the outside of the polygon. In the figure above, check "regular" and notice that this is the case. Although there are two possible exterior angles at each vertex (see note below) we usually only consider one per vertex, selecting the ones that all go around in the same direction, clockwise in the figure above. Taken one per vertex in this manner, the exterior angles always add to 360° This is true no matter how many sides the polygon has, and regardless of whether it is regular or irregular, convex or concave. In the figure above, adjust the number of sides, switch to irregular and drag a vertex to see that this is true. In the figure above click on 'reset' and check "both". You will see that both angles at each vertex are always congruent (same measure). This is because they form a pair of vertical angles, which are always congruent. Drag the vertices around and convince yourself this is true. Concave case If the polygon is concave, things are a little trickier. A concave polygon has one or more vertices "pushed in" so they point towards the interior. In the figure above, uncheck "regular" and drag a vertex in towards the interior of the polygon. Notice that the exterior angle flips over into the inside of the polygon and becomes negative. If you add the exterior angles like before, they still add to 360°, you just have to remember to add the negative angles correctly. Exterior and Interior angles are supplementary At any given vertex, the interior angle is supplementary to an exterior angle. See Interior/Exterior angle relationship in a polygon. Walking the polygon In the figure above, imagine the polygon drawn on the ground. Stand on one of the sides and face along the line. Now if you walk around the polygon along each line in turn, you will eventually wind up back where you started, facing the same way. So you must have turned through a total of 360°, a full circle. This confirms that the exterior angles, taken one per vertex, add to 360° The sum of exterior angles - watch out! In most geometry textbooks they say flatly that the exterior angles of a polygon add to 360° This is only true if: You take only one per vertex, and Take all the angles that point in the same direction around the polygon. But in many cases they fail to state these conditions. In the figure at the top of the page, check the "Both" checkbox. You will see there are two per vertex and they actually add to 720° (360 times 2) So if you are asked "What is the sum of the exterior angles of a polygon?" without any conditions, you will have to guess which one they mean. Usually they mean taking one per vertex, and the answer is 360°, although strictly speaking this is wrong.

options
34/x =20/16
20/16 = 34/x
16/20 = x/34
20/16 = x/34
Answers
Using Thales, 34/x=20/16
Answer A
To find the distance the ball traveled after it bounces off the wall, we can use the proportion 34/x = 20/16, which simplifies to x = 27.2 inches.
To find the proportion that can be used to find the distance, x, the ball traveled after it bounces off the wall, we can use the equation:
34/x = 20/16
After cross multiplying, we get:
34 × 16 = 20x
Simplifying further:
544 = 20x
Dividing both sides by 20, we find:
x = 27.2
Therefore, the distance the ball traveled after it bounces off the wall is 27.2 inches.

the answer is
Raj is 15 years old
Zia is 12 years old
Final answer:
Zia's age is 12 and Raj's age is 15
Explanation:
To solve this problem, we can set up two equations using the given information. Let's assume Zia's age is x. Since Raj is 3 years older than Zia, Raj's age can be represented as x + 3.
The first equation is [tex]x^2 + (x + 3)^2 = 369.[/tex]
Simplifying this equation, we get [tex]x^2 + x^2 + 6x + 9 = 369.[/tex]
Combining like terms, we have [tex]2x^2 + 6x + 9 = 369.[/tex]
Next, we can rearrange the equation by subtracting 369 from both sides and combining like terms to get [tex]2x^2 + 6x - 360 = 0.[/tex]
Now, we can solve this quadratic equation for x using factoring, completing the square, or the quadratic formula. The solutions are x = -15 and x = 12.
Since age cannot be negative, Zia's age is 12 and Raj's age is 12 + 3 = 15.
