How many diagonals can be drawn from each vertex of a 15-gon?
11
18
12
8
None of these answers are correct.
Answer:
Correct option: third one -> 12
Step-by-step explanation:
In a polygon with 'n' vertex, we can trace diagonals from one vertex to all vertices, except to the vertex chosen and the two adjacent vertices (because we would have sides and not diagonals), so we would have 'n - 3' diagonals.
If we have a polygon with 15 vertex, the number of diagonals from one vertex is 15 - 3 = 12.
Correct option: third one
Simplify 9(x+7)^2/3(x-1)(x+7)
is this correct? if not what is the answer
Answer:
x = 50
Step-by-step explanation:
You are correct.
x + m<PQS + m<PSQ = 180
m<PQS = m<QRT = 70
m<QST + m<PSQ = 180
120 + m<PSQ = 180
m<PSQ = 60
x + 70 + 60 = 180
x + 130 = 180
x = 50

In a half-kilo jar of legumes there are 2.5g of fat. In another 400g can of legumes B there is 2.1g of fat. Are these data in proportion? If the data is not in proportion, in which of the two cans is there more fat proportionally?
Answer:
no400 g canStep-by-step explanation:
A half-kilo jar is 500 grams, so a 400 g can would be 4/5 the weight. 4/5 of 2.5 g of fat would be 2.0 g of fat. The 400 g can has 2.1 g, so has more fat, proportionally, than its weight would suggest.
The fat is not proportional to the can sized. The 400 g can has more fat, proportionally.

Complete the factorization of 3x ^ 2 - 10x + 8 3x^ 2 -10x+8=(x- Box x-4)
Answer:
[tex]3x^2-10x+8=(x-x_1)(x-x_2)=(x-2)(x-\frac{4}{3})[/tex]
Step-by-step explanation:
The general form of a quadratic polynomial is given by:
[tex]ax^2+bx+c[/tex] (1)
You have the following polynomial:
[tex]3x^2-10x+8[/tex] (2)
In order to complete the factorization you can use the quadratic formula, to obtain the roost of the polynomial. The quadratic formula is given by:
[tex]x_{1,2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex] (3)
By comparing the equation (1) with the equation (2) you obtain:
a = 3
b = -10
c = 8
Then, you replace these values in the equation (3):
[tex]x_{1,2}=\frac{-(-10)\pm \sqrt{(-10)^2-4(3)(8)}}{2(3)}\\\\x_{1,2}=\frac{10\pm2}{6}\\\\x_1=2\\\\x_2=\frac{4}{3}[/tex]
Then, the factorization of the polynomial is:
[tex]3x^2-10x+8=(x-x_1)(x-x_2)=(x-2)(x-\frac{4}{3})[/tex]

If £31 = 500 rubles, how many £ are in 992 rubles? Give your answer to 2 dp.
Answer:
There are £61.50 in 992 rubles
Step-by-step explanation:
Here, we shall be doing some currency conversions.
Now,
£31 = 500 rubles
Then;
£x = 992 rubles
To get c, what we do is simply cross multiply
£x * 500 rubles = £31 * 992 rubles
£x = (£31 * 992 rubles)/500 rubles
£x = £61.504
which is £61.50 to two decimal places
A cylindrical container with a radius of 6 cm and a height of 10 cm is filled with water to a depth of 6 cm. A sphere with a radius of 3 cm is placed at the bottom of the container.
a) What is the volume of the water to the nearest tenth?
b) What is the volume of the sphere to the nearest tenth?
c) How much higher does the water level rise in the container, to the nearest tenth, after the
sphere is placed inside?
Answer:
a. 452.4 cm³ to the nearest tenth b. 113.1 cm³ to the nearest tenth
c. 5.0 cm to the nearest tenth
Step-by-step explanation:
a. The volume of the water V₁ = πr²h since it is in a cylindrical container. r = 6 cm and h = 10 cm - 6 cm = 4 cm (since it is filled to a depth of 6 cm measuring from the top, so we have a height from the bottom of 10 cm - 6 cm = 4 cm).
So, V₁ = πr²h
= π × (6 cm)² × 4 cm
= 452.39 cm³
= 452.4 cm³ to the nearest tenth
b. The volume of the sphere V₂ = 4πr³/3 where r = radius of sphere = 3 cm.
V₂ = 4πr³/3
= 4π(3 cm)³/3
= 113.1 cm³ to the nearest tenth
c. When the sphere is placed in the container, the new volume of water in the container would be V = V₁ + V₂
So V = 452.4 cm³ + 113.1 cm³ = 565.5 cm³
Since the volume of water is still the volume of a cylinder, its height h is
h = V/πr²
= 565.5 cm³/π(6 cm)²
= 5.0 cm to the nearest tenth

The volume of a right-rectangular prism is 15 cubic feet. The prism is 2½ feet wide and has a height of ½ foot. How long, in feet, is the rectangular prism?
Answer:
12 feet
Step-by-step explanation:
To get the volume of a rectangular prism, you must multiply the height, width, and length of the prism. So to get your answer, you must multiply 2 1/2 and 1/2, then divide 15 feet by the answer. 2 1/2 × 1/2 × 12 = 15

What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
Some of the coordinates from the graph are:
(1, 18), (2, 36), and (3, 54)
Now,
The rate of change between (1, 18), and (2, 36).
Slope = (36 - 18) / (2 - 1) = 18
The rate of change between (2, 36), and (3, 54).
Slope = (54 - 36) / (3 - 2) = 18
This means,
That for every hour there is an earning of $18.
Thus,
The graph shows that for every hour the earnings are $!8.

Franco made a dozen muffins for his party. Upon taking them out of the oven,
he noticed that 2 of the muffins were badly burned. Franco served of the remaining muffins.
10
Which equation shows the fraction of the non-burned muffins that remains?
Answer:
Option B.
Step-by-step explanation:
This question is incomplete; find the complete question with the attachment.
Franco made number of muffins = a dozen
A dozen muffins = 12 muffins
Number of muffins were burned = 2
Remaining muffins = 12 - 2 = 10
Franco served 7 of the remaining non-burned muffins,
Fraction of muffins served = [tex]\frac{7}{10}[/tex]
Remaining muffins = 3
Fraction of remaining muffins = [tex]\frac{3}{10}[/tex]
Fraction of remaining non-burned muffins we can get from,
[tex]\frac{10}{10}-\frac{7}{10}=\frac{3}{10}[/tex]

Answer:
~120.4 cm
Step-by-step explanation:
Applying the Pythagorean theorem:
height^2 + 127^2 = 175^2
=> height^2 = 175^2 - 127^2
=> height^2 = 14496
=> height = sqrt(14496) = ~120.4 cm

If the point (a,3) lies on the graph of the equation 5x+y=8, then a=
Answer:
a = 1
Step-by-step explanation:
The given equation is:
=> 5x+y = 8
Also,
Point = (x,y) = (a,3)
So, x = a , y = 3
Putting this in the above equation
=> 5(a)+3 = 8
=> 5a = 8-3
=> 5a = 5
Dividing both sides by 5
=> a = 1

Answer:
3pi/4 =x and 5pi/4 =x
Step-by-step explanation:
cos x + sqrt(2) = - cos x
subtract cos x from each side
cos x - cosx + sqrt(2) = - cos x - cos x
sqrt(2) = -2 cos x
Divide each side by -2
-sqrt(2) / 2 =-2 cos (x) /-2
-sqrt(2) /2 =cos (x)
Take the inverse cos of each side
cos(-1)(-sqrt(2) /2) =cos^-1(cos (x))
3pi/4 =x and 5pi/4 =x
Answer:
Here's your answer:
3pi/4 =x and 5pi/4 =x
cos x + sqrt(2) = - cos x
subtract cos x from each side
cos x - cosx + sqrt(2) = - cos x - cos x
sqrt(2) = -2 cos x
Divide each side by -2
-sqrt(2) / 2 =-2 cos (x) /-2
-sqrt(2) /2 =cos (x)
Take the inverse cos of each side
cos(-1)(-sqrt(2) /2) =cos^-1(cos (x))
3pi/4 =x and 5pi/4 =x

Frequency : - 12 - - - 9 - - - 11 - - 8 - - - 12 - - - 14
What is the experimental probability of spinning an odd
P(spinning an odd) = (number of occurrence of an event / number of trials)
Odd outcomes = 1, 3, 5
Frequency of 1 = 12
Frequency of 3 = 11
Frequency of 5 = 12
Number of occurrences of odd = (12 + 11 + 12) = 35
Number of trials = 66
Therefore,
P(spinning an odd) = 35 / 66
