Answer: 33

Step-by-step explanation:

all of the numbers add up to 180 degrees

Answer:

33

Step-by-step explanation:

To find the degree, remember: a triangles angles will always add up to 180°. So, add your degrees, then subtract that from 180:

[tex]114+33=147\\180-147=33[/tex]

z=33°

Answer:

59 Adults And 147 Children

Step-by-step explanation:

Since there were a total of 206 people, this means that x%2By=206

Also, because "The Jurassic Zoo charges $11 for adult admission and $9 for each child. the total bill for the 206 people from a school trip was $1972", this means that 11x%2B9y=1972

So we have the system:

system%28x%2By=206%2C11x%2B9y=1972%29

Let's solve it by substitution

Now in order to solve this system by using substitution, we need to solve (or isolate) one variable. I'm going to solve for y.

So let's isolate y in the first equation

x%2By=206 Start with the first equation

y=206-x Subtract x from both sides

y=-x%2B206 Rearrange the equation

---------------------

Since y=-x%2B206, we can now replace each y in the second equation with -x%2B206 to solve for x

11x%2B9highlight%28%28-x%2B206%29%29=1972 Plug in y=-x%2B206 into the second equation. In other words, replace each y with -x%2B206. Notice we've eliminated the y variables. So we now have a simple equation with one unknown.

11x%2B%289%29%28-1%29x%2B%289%29%28206%29=1972 Distribute 9 to -x%2B206

11x-9x%2B1854=1972 Multiply

2x%2B1854=1972 Combine like terms on the left side

2x=1972-1854Subtract 1854 from both sides

2x=118 Combine like terms on the right side

x=%28118%29%2F%282%29 Divide both sides by 2 to isolate x

x=59 Divide

-----------------First Answer------------------------------

So the first part of our answer is: x=59

Since we know that x=59 we can plug it into the equation y=-x%2B206 (remember we previously solved for y in the first equation).

y=-x%2B206 Start with the equation where y was previously isolated.

y=-%2859%29%2B206 Plug in x=59

y=-59%2B206 Multiply

y=147 Combine like terms

-----------------Second Answer------------------------------

So the second part of our answer is: y=147

-----------------Summary------------------------------

So our answers are:

x=59 and y=147

This means that 59 adults and 147 children went to the zoo.

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

96 square units

120 square units

Area of the rectangle

The area of a right triangle is given by

[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:

[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.

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:

Step-by-step explanation:

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: The correct answer is C. Because, when two figures are congruent all their measurements are the same.

Step-by-step explanation:

The number n = 4.768 as a fraction is A = 596/125

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the number be represented as n

Now , let the fraction be A

where the value of n = 4.768

And , to convert a decimal to a fraction, we can write the decimal as a fraction with the decimal value in the numerator and a power of 10 in the denominator that corresponds to the number of decimal places.

For 4.768, the decimal value is 768, which is three decimal places to the right of the decimal point. Therefore, we can write:

4.768 = 4 + 0.768

= 4 + 768/1000

= 4000/1000 + 768/1000

= 4768/1000

This fraction can be reduced by dividing both the numerator and denominator by their greatest common factor, which is 8:

4768/1000 = (8 × 596)/(8 × 125)

A = 596/125

Hence , the fraction is A = 596/125

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

Answer: 26.7%

Step-by-step explanation:

The probability that the leftover students were both male is 26.7%. Hence the correct option is B.

The probability that both selected students are male can be calculated as follows:

Determine the probability of selecting a male student for the first pick: P(Male) = 8/(8+7) = 8/15

Since the first student selected was male, the probability of the second student being male as well is: P(Second Male|First Male) = 7/(8+6) = 7/14

Multiply the probabilities together to get the probability of both selected students being male: P(Both Male) = P(Male) * P(Second Male | First Male) = (8/15) * (7/14) = 4/15 or approximately 26.7%
