A teacher asks four students the question, “Can a triangle have more than one right angle, and why?” The table lists the students’ responses.
Considering the sum of the internal angles of a triangle, it is found that the correct student is Paige.
What is the sum of the internal angles of a triangle?The sum of the three internal angles of a triangle is of 180º, and none of the angles can be zero.
Hence, a triangle can have at most one right angle(angle of 90º), and researching the question on the internet, the student who states this is Paige.

What is the median of this data set? {29, 22, 23, 31, 29, 29, 22, 23} Enter your answer in the box.
Answer:
The median is 26
Step-by-step explanation:
A "median" is equivalent to, when the terms are arranged in the proper order, whichever term is in the "middle".
So- first, arrange the terms in ascending order.
[22, 22, 23, 23, 29, 29, 29, 31]
There are an even number- eight- terms in total, so we will take the average of the two "middle" terms.
(29+23)/2; 29 and 23 are the "middle" terms, and there are two of them.
(52)/2 = 26
Therefore, the median is 26.

what is the area of this shape? the answer isn't 92 cm squared
Answer:
80cm^2
Explanation:
Okay to do this, it's often better to find the area of each shape separately.
Let's start with the top rectangle:
4cm*7cm = 28cm^2
Bottom rectangle:
to find the length of it, we just add 3cm and 7cm which = 10cm
so:
10cm*4cm = 40cm^2
And finally the triangle:
to find the bottom side: 13cm - 7cm - 3cm = 3cm
to find the height: 4cm + 4cm = 8cm
so:
8cm*3cm*/2 = 24cm/2
= 12cm^2
Now we add them all up:
28 + 40 + 12 = 80cm^2
Answer:
Corrected Question:[ Refer to the above attachment ]
Solution:In the given figure there are two shapes:
A RectangleA TriangleFirst, we have to find the area of Rectangle ABGF & DCGE. After that, area of triangle CHB.
1) Area of Rectangle ABGF:
As, we know:
Formula for Area :-
★ Length × Breadth ★
where,
Length = FA = 4cm Breadth = GF = 10cm ( 7+3 )➝ 4 cm × 10 cm
➝ 40 cm²
Hence, the area of Rectangle ABGF is 40cm².
2) Area of Rectangle DCGE:
As, we know:
Formula for Area :-
★ Length × Breadth ★
where,
Length = ED = 4cm Breadth = DC = 7cm➝ 4 cm × 7 cm
➝ 28 cm²
Hence, the area of Rectangle DCGE is 28cm².
3) Area of Triangle CHB:
As, we know:
Formula for Area :-
★ ½ ( base × height ) ★
where,
Base = 3cm Height = 8cm➝ ½ ( 3cm × 8cm )
➝ ½ ( 24cm )
➝ ½ × 24cm
➝ 12 cm²
Hence the Area of Triangle CHB is 12cm².
Now, Area of Given Shape is:
➝ 40cm² + 28cm² + 12cm²
➝ 52cm² + 28cm²
➝ 80cm²
Thus, the area of the given shape is 80cm².

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 70 The truck is transporting 60 large boxes and 55 small boxes. If the truck is carrying a total of 4050 pounds in boxes, how much does each type of box weigh?
Step-by-step explanation:
x = weight of a small box
y = weight of a large box
x + y = 70 pounds
55x + 60y = 4050 pounds
from the first equation we get
x = 70 - y
and we can use that identity in the second equation :
55(70 - y) + 60y = 4050
3,850 - 55y + 60y = 4050
5y = 200
y = 40 pounds
x = 70 - y = 70 - 40 = 30 pounds
so, a small box weighs 30 pounds, and a large box weighs 40 pounds.

many people in 6th grade play an instrument?
Answer:

Step-by-step explanation:
By setting up the equation 2/5=x/300, we can cross cancel, changing the equation into 5x=600, and by dividing both sides by 5, the 5 in 5x cancels out and 600 divided by 5 is 120.

How much greater is the average rate of change over the interval [6,8] than the interval [5,7]?
============================================================
Explanation:
The average rate of change is the same as the slope of the line through the endpoints mentioned.
The interval [6, 8] means that we're talking about [tex]6 \le x \le 8[/tex]
When x = 6, we have y = f(x) = 1178When x = 8, we have y = f(x) = 2742So we're tasked to find the slope of the line through (6,1178) and (8,2742)
We'll use the aptly named slope formula.
[tex](x_1,y_1) = (6,1178) \text{ and } (x_2,y_2) = (8,2742)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{2742 - 1178}{8 - 6}\\\\m = \frac{1564}{2}\\\\m = 782\\\\[/tex]
The slope through those two endpoints is 782, which is the average rate of change on the interval [6, 8].
------------------
For the interval [5,7] we have [tex]5 \le x \le 7[/tex]
According to the function table,
When x = 5, y = 690When x = 7, y = 1852Like before, use the slope formula to find the slope through (5,690) and (7,1182)
[tex](x_1,y_1) = (5,690) \text{ and } (x_2,y_2) = (7,1182)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{1182 - 690}{7 - 5}\\\\m = \frac{492}{2}\\\\m = 246\\\\[/tex]
This is the average rate of change on the interval [5,7].
------------------
The last step is to subtract the slopes:
782 - 246 = 536 which is the final answer

You estimate that there are 52 marbles in a jar. The actual amount is 88 marbles. Find the percent error. Round to the nearest
tenth of a percent if necessary.
Answer:
We know that there are total 12 marbles are not there because 48-36=12. Now, I take:
12÷48=0.25 or 25%. As a result, the percent error is 25%. Hope it helps!
Step-by-step explanation:
The percentage error is 40.9%.
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that, the estimated value is 52 and the actual value is 88.
The percent error is given
error% = (|estimated - actual|)/actual × 100 %
error% = (|52 - 88|)/88 × 100 %
error% = 40.9%
Hence, the percentage error is 40.9%.

Given quadrilateral ABCD with vertices A (1,1), B (5,2), C (8, -6), and D (0, -8). Which statements are correct
A quadrilateral is a shape with four vertices
The true statement about the quadrilateral ABCD is that the quadrilateral has unequal lengths
How to determine the true statement?The coordinates of the vertices are given as:
A = (1,1)
B = (5,2)
C = (8, -6)
D = (0, -8)
Next, we calculate the distance between the vertices using the following distance formula
[tex]d=\sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]
So, we have:
[tex]AB=\sqrt{(1 -5)^2 + (1 -2)^2} = \sqrt{17}[/tex]
[tex]BC=\sqrt{(5 - 8)^2 + (2 +6)^2} = \sqrt{73}[/tex]
[tex]CD=\sqrt{(8 - 0)^2 + (-6 + 8)^2} = \sqrt{68}[/tex]
[tex]DA=\sqrt{(0 - 1)^2 + (-8 - 1)^2} = \sqrt{82}[/tex]
From the above computation, we have the lengths to be unequal
Hence, the true statement about the quadrilateral ABCD is that it has unequal lengths

by a scale factor of 1.5?
Answer:
the dilated coordinates are (12, 9), (6, 9), (12, -6), (6, -6)
Step-by-step explanation:
The dilation factor multiplies each coordinate value when the center is the origin.

(8, 6) ⇒ 1.5(8, 6) = (12, 9)
(4, 6) ⇒ 1.5(4, 6) = (6, 9)
