By identifying triangle MNO as a right-angled triangle with MO as the hypotenuse, the angles are listed from smallest to largest based on their opposite sides: angle M (smallest), angle O (middle), and angle N (largest at 90 degrees).

The student has asked to list the angles of triangle right -angled MNO in order from smallest to largest, given that NM = 3 cm, NO = 4 cm, and MO = 5 cm. This is a case of a right-angled triangle where the sides satisfy the Pythagorean theorem, with MO being the hypotenuse. The angles of a triangle are inversely proportional to their opposite sides. Therefore, the angle opposite the longest side (MO) is the smallest, and the angle opposite the shortest side (NM) is the largest.

Steps to determine angle size:

Use the Pythagorean theorem to confirm the right angle.

Identify the smallest and largest sides to determine the smallest and largest angles.

Apply the fact that the sum of angles in a triangle is 180 degrees to find the middle angle.

Since 3² + 4² = 5², triangle MNO is a right-angled triangle with the right angle at angle N.

The smallest angle is thus at M, opposite the longest side MO.

The largest angle is at O, opposite the shortest side NM.

As angle N is 90 degrees, the remaining angle at O must be the second-largest angle.

Answer:

Area of rectangle: 256

Area of triangle 1: 24

Area of triangle 2: 16

Area of triangle 3: 96

Area of trapezoid: 120

Step-by-step explanation:

I just did the question on the thing so Ik I'm right.

-The graph measures by twos. To get the area of the rectangle get the base times height of it. That would be 16x16=256.

-Get base (8) times height (6) of triangle 1 then divide by 2, remember to count the squares by 2 for finding all areas. The formula would be 1/2(b)(h) because dividing by 2 is the same as multiplying times 1/2. Plug it in and     (8)(6)=48 then divide by 2 which equals 24.

-Same formula for triangle 2. Plug it in and (8)(4)=32 and divide by 2 and it equals 16.

-Same formula for triangle 3. Plugged in is (12)(16)=192 divide by 2 and it equals 96.

-To find the area of the trapezoid get your rectangle area (256) and subtract all the triangle areas. So 256 - 6 - 16 - 96 = 120.

The area of the given shapes are required.

256 square units

24 square units

16 square units

96 square units

120 square units

Area of the rectangle

[tex]A_r=(20-4)\times(20-4)\\\Rightarrow A_r=256\ \text{square units}[/tex]

The area of a right triangle is given by

[tex]\dfrac{1}{2}bh[/tex]

where

b = Base

h = Height

Every triangle here is a right triangle.

Triangle 1

[tex]b=20-14=6\ \text{units}[/tex]

[tex]h=12-4=8\ \text{units}[/tex]

[tex]A_1=\dfrac{1}{2}\times 6\times 8\\\Rightarrow A_1=24\ \text{square units}[/tex]

Triangle 2

[tex]b=20-16=4\ \text{units}[/tex]

[tex]h=20-12=8\ \text{units}[/tex]

[tex]A_2=\dfrac{1}{2}\times 4\times 8\\\Rightarrow A_2=16\ \text{square units}[/tex]

Triangle 3

[tex]b=20-4=16\ \text{units}[/tex]

[tex]h=16-4=12\ \text{units}[/tex]

[tex]A_3=\dfrac{1}{2}\times 16\times 12\\\Rightarrow A_3=96\ \text{square units}[/tex]

Area of trapezoid is Area of the rectangle minus Area of all the triangles.

[tex]A=A_r-(A_1+A_2+A_3)\\\Rightarrow A=256-(24+16+96)\\\Rightarrow A=120\ \text{square units}[/tex]

Answer:

No, They are not equivalent

Step-by-step explanation:

The two expressions are only said to be equivalent if they are the same regardless of whatever value the variable(s) is.

The variable in this question is x.

To prove this, we equate both expressions:

[tex]10x + 6 = 5x + 11[/tex]

[tex]10x - 5x = 11 - 6\\\\\\5x = 5\\\\\\x = 1[/tex]

This shows that they have the same value ONLY when x is 1.

This is why Andre says that they are equivalent, but they are not.

No, I do not agree with Andre because the two equations 10x + 6 and 5x + 11 are indeed equivalent.

No, I do not agree with Andre. Two equations are considered equivalent if they have the same solution for all values of x.

Let's check if 10x + 6 and 5x + 11 are equivalent by substituting x = 1 into both equations:

For 10x + 6: 10(1) + 6 = 10 + 6 = 16

For 5x + 11: 5(1) + 11 = 5 + 11 = 16

We can see that both equations indeed equal 16 when x is 1, so Andre is correct in this case. 10x + 6 and 5x + 11 are equivalent equations.

Answer: 4x+10 cm

Step-by-step explanation:

length of rectangle= 2x-1cm

breadth of rectangle= 6 cm

perimeter of rectangle= 2(L+B)

                                    = 2( 2x-1+6)                                 (substituting the values)

                                    =2(2x+5)

                                    =4x+10

Therefore, the perimeter of the rectangle is 4x+10 cm.

Answer:  

P(red then green) = 5/8 * 3/7 = 15/56

Step-by-step explanation: Since this is a logical "and" case, we have to multiply the separate events' probabilities...thus  P(red then green) = 5/8 * 3/7 = 15/56

Answer:

3/28

Step-by-step explanation:

3 red+ 5 green = 8 marbles in the jar

1st marble:

P(red) = number of red/ total = 3/8

We keep the marble

2 red+ 5 green = 7 marbles in the jar

P(green) = number of green/ total = 2/7

P (red,keep,green) = P(red)* P(green) = 3/8*2/7 = 6/56 = 3/28

Answer:

[tex]A = 40w-w^2[/tex]      

Step-by-step explanation:

We are given the following in the question:

Perimeter of rectangle = 80 inches.

Let l be the length and w be the width of rectangle.

Perimeter of rectangle =

[tex]P= 2(l+w)[/tex]

Putting values, we get,

[tex]80 = 2(l+w)\\40 = l+w\\\Rightarrow l = 40 - w[/tex]

Now, we have to find the area of the rectangle in terms of w.

Area of rectangle =

[tex]A = l\times w[/tex]

Putting values, we get

[tex]A = (40-w)w\\A = 40w-w^2[/tex]

is the required expression of area of rectangle in terms of w.

Yes, the perimeter is used to calculate the length of the rectangle in the term of w.

Answer:

  $70

Step-by-step explanation:

The excess amount is 20% of the goal. The given amount is 120% of the goal, so the proportion of the given amount that is excess is ...

  (20% of goal)/(120% of goal) = 1/6

Then the excess is (1/6)($420) = $70.

You raised $70 more than the $350 goal.

The original fundraising goal was $350, and since $420 was raised, which is 120% of the goal, $70 more was raised than the goal.

To find out how much more was raised than the goal during the fundraising event, start by understanding the percentage given. The $420 raised is 120% of the goal, which means the goal amount represents 100%. To calculate the original goal, you should divide the amount raised by the percentage raised (expressed as a decimal), so you divide 420 by 1.2 (since 120% as a decimal is 1.2).

Now, calculate the goal amount:
420 / 1.2 = $350

Therefore, the original goal was $350. Since the amount raised was $420, we subtract the goal from the amount raised to determine how much more was raised:
420 - 350 = $70.

Thus, the amount raised exceeded the goal by $70.

Juana sold an average of 12 hot chocolates per hour during her 7-hour work shift (excluding her lunch break).

The question asks us to calculate the average hot chocolate sold per hour by Juana during her shift. Juana worked an 8-hour day but took a 1-hour lunch break, leaving 7 hours of work time.

To find the average sold per hour, the total amount sold (84 hot chocolates) should be divided by the number of hours worked (7 hours). The calculation is as follows:

84 hot chocolates ÷ 7 hours = 12 hot chocolates per hour

Therefore, Juana sold an average of 12 hot chocolates per hour during her shift.

Answer:

x=110 i think

Step-by-step explanation:

x+20+2x-70+x+x+20+x+90

=6x+60

6x+60=720

6x=(720-60)

6x=660

660/6=110

x=110

hope this helps!

Answer:

Step-by-step explanation:

sum of all angles of polygon = (n-2)*180   {n is no of sides}

= (6-2)*180 = 4*180 = 720

90 + 2x-70 + x+20 +x + x+20 + x = 720

Bring like terms together

90 - 70 + 20 + 20 + 2x + x + x + x + x =720

60 + 6x = 720

6x = 720 - 60

6x = 660

x = 660/6

x = 110
