Answer:
Q1: 18 degrees
Q2: 60 sides
Step-by-step explanation:
The sum of the exterior angles is always 360 degrees. With this, do 360/20 to get the amount of sides that are within the shape.
360/20 --> 18 degrees.
Now with the interior angles, it can be found with the equation ((n-2) * 180 degrees) / n = Angle Given. With this, plug 174 degres into your equation.
(n-2) * 180 degrees) / n = Angle Given
(n-2) * 180 degrees) / n = 174
180n -360 / n = 174
180n -360 / 174n
360 = 6n
n = 60
It would be 60 sides.

A cooking school is teaching students how to make pasta noodles. The line plot displays how much flour each student used. How many total cups of flour did the students use to make the pasta?
Answer:
[tex]Total = 11\frac{1}{8}\ cups[/tex]
Step-by-step explanation:
Given
See attachment for plot
Required
Total number of cups used
The number of dot on each dataset represent the number of student
So, to get the total number of cups, we simply add the product of the number of cups and the number of student for each data item
So, we have:
[tex]Total = \frac{1}{8} * 6 + \frac{1}{4} * 5 + \frac{3}{8} * 2 + \frac{1}{2}*0 + \frac{5}{8} * 4 + \frac{3}{4} * 2 + \frac{7}{8} * 5[/tex]
[tex]Total = \frac{6}{8} + \frac{5}{4} + \frac{6}{8} + 0+ \frac{20}{8} + \frac{6}{4} + \frac{35}{8}[/tex]
Solve
[tex]Total = \frac{6+10+6+0+20+12+35}{8}[/tex]
[tex]Total = \frac{89}{8}[/tex]
[tex]Total = 11\frac{1}{8}\ cups[/tex]

what would be the leading coefficient of f(x)=6-x+7x^2
Answer:
7
Step-by-step explanation:
The leading coefficient of the given expression is 7.
What is coefficient?A coefficient is a factor that is multiplied by a variable or a term in an expression. It can be a number or a symbol representing a constant value. For example, in 7x - 3y + 5, the coefficients are 7, -3, and 5.
Given that a quadratic function f(x) = 6-x+7x², we need to find the leading coefficient,
So, rearranging the terms in the function in standard form,
f(x) = 7x²+x-6
The leading coefficient is the coefficient of the term with the highest power or degree in a polynomial,
Here, the highest power coefficient is 7.
Hence, the Leading coefficient of the given expression is 7.

95 - 3/4 what is the value of the expression
Answer:377 /4 = 94 and 1 / 4 =94.25
Step-by-step explanation:
Subtract
95 − 3 /4
= 377 / 4
Convert integer to fraction
95 = 95 / 1
Find common denominator
95 over 1
− 3 over 4
= ( 95 × 4 ) over ( 1 × 4 )
− ( 3 × 1 ) over ( 4 × 1 )
= 380 over 4
− 3 over 4
4 is the least common multiple of denominators 1 and 4. Use it to convert to equivalent fractions with this common denominator.
Subtract
380 over 4
− 3 / 4
= ( 380 − 3 ) / 4
= 377 /4
Simplify
377 / 4
= 94 and 1 /494
Reduce fraction to lowest terms
1 is the greatest common divisor of 377 and 4. The result can't be further reduced.
Step 2 of 2: Simplify, sub-step b: Convert improper fraction to mixed number.
Convert improper fraction to mixed number
377 /4
= 94 1 /4
377 ÷ 4 = 94 remainder 1
By writing the whole number as a fraction, we will see that the solution is 377/4
How to solve the expression?
Here we want to take the difference between a whole number and a fraction:
95 - 3/4
To do this, we need to write the whole number as a fraction, to do it, we multiply and divide it by 4:
95 = (4/4)*95 = 380/4
Now we rewrite our expression as:
95 - 3/4 = 380/4 - 3/4 = 377/4
This is the solution of the expression.

A storage bin is a rectangular prism that measuring 114 cm long by 56 cm high by
56 cm deep. What is the surface area of the exterior, in square feet?
Answer:
33.12 square feet
Step-by-step explanation:
Step 1
We convert the dimensions to feet
1 cm = 0.0328084 feet
Length = 114cm
Hence
114 cm = 114 × 0.0328084 feet
= 3.74016 feet
≈ 3.7 feet
Height = 56cm
Hence
56 cm = 56 × 0.0328084 feet
= 1.83727 feet
≈ 1.8 feet
Depth(width) = 56cm
Hence
56 cm = 56 × 0.0328084 feet
= 1.83727 feet
≈ 1.8 feet
Step 2
The surface area of the rectangular prism
A=2(wl+hl+hw)
=2× (1.8×3.7+ 1.8×3.7 + 1.8 ×1.8)
≈33.12 square feet

So I have already solved this problem but I don’t really understand how I solved it if anyone could help me I would really appreciate it!
If the interest for 3 months is $260, then the total interest for the year is 4 times $260 or $1040.
Let x = amount invested at one of the rates, say 6%. This leaves the rest of the $16,000 or (16000-x) to be invested at the other rate, at 8%.
The equation is basically that the interest earned for 1 year at 6% plus the interest earned for the year at 8% is equal to the total interest for the year, or $1040.
.06x + .08(16000-x) = 1040
.06x + .08(16000) - .08x = 1040
-.02x + 1280 = 1040
Subtract 1280 from each side:
-.02x = 1040 - 1280
-.02x = -240
To solve for x, divide both sides by -.02, remembering that a negative divided by a negative is a negative.
x = 240/.02
Either divide with a calculator, or multiply numerator and denominator by 100 to eliminate the decimal.
x = 24000/2 = $12000 at 6%
16000-x = 16000-12000 = $4000 at 8%
If 72 x 96 = 6927, 58 x 87 = 7885, then 79 x 86 = ?
79 x 86 is equal to 6,794.

Answer:
27 cubic meters
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Area of cube = 54 square meters
Let, Side = a
Then, Area of cube = 6[tex]a^{2}[/tex]
54 = 6 [tex]a^{2}[/tex]
[tex]a^{2}[/tex] = 9
a = 3
So, we can calculate the volume of cube by using following formula
Volume of cube = [tex]a^{3}[/tex]
By putting the value in the formula, we get
Volume of the cube = [tex]3^{3}[/tex]

The equation of proportion is y equals 2 over 9 x and , y = ( 2/9 )x
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
where y varies directly with x, and y is 16 when x is 72
So , when x = 72 , y = 16
y = kx
16 = k ( 72 )
Divide by 72 on both sides , we get
k = 16 / 72
k = 2/9
Therefore , the value of A is y = ( 2/9 )x
Hence , the equation is y = ( 2/9 )x
