Find the area. The figure is not drawn to scale.
Find the volume of the sphere shown. Give each answer rounded to the nearest cubic unit.
Answer:
[tex](a)\ Area = 28.12cm^2[/tex]
[tex](b)\ Volume = 1437.33cm^3[/tex]
Step-by-step explanation:
Solving (a): The parallelogram
[tex]h = 7.6[/tex] --- height
[tex]b = 3.7[/tex] --- base
The area is calculated usng:
[tex]Area = base * Height[/tex]
[tex]Area = 3.7 * 7.6[/tex]
[tex]Area = 28.12cm^2[/tex]
Solving (b): The sphere
[tex]d = 14cm[/tex]
Required
The volume
First, calculate the radius
[tex]r = d/2[/tex]
[tex]r = 14cm/2 = 7c,[/tex]
The volume is calculated using:
[tex]Volume = \frac{4}{3} \pi r^3[/tex]
This gives:
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 7^3[/tex]
[tex]Volume = \frac{4}{3} * 22 * 7^2[/tex]
[tex]Volume = \frac{4}{3} * 1078[/tex]
[tex]Volume = \frac{4*1078}{3}[/tex]
[tex]Volume = \frac{4312}{3}[/tex]
[tex]Volume = 1437.33[/tex]

Suppose we want to choose 6 letters with out replacement from 13 distinct letters. How many ways can this be done if the order of the choices is not relevant? How many ways can this be done if the order of the choices is relevant?
Suppose we want to choose 6 letters with out replacement from 13 distinct letters.
a. The number of ways this be done if the order of the choices is not relevant is 1,235,520 ways.
b. The number of ways this be done if the order of the choices is relevant is 1716 ways.
How to find the number of ways?a. Number of ways if choice are not relevant
[tex]^nP_r = n!/ (n-r)![/tex]
Where:
n =13
r = 6
So,
[tex]^1^3P_6[/tex] = 13! / (13 - 6)!
[tex]^1^3P_6[/tex] =6,227,020,800 /7!
[tex]^1^3P_6[/tex] =6,227,020,800/5,040
[tex]^1^3P_6[/tex] = 1,235,520 ways
b. Number of ways if choice are relevant
[tex]^nC_r =n!/ r! (n-r)![/tex]
[tex]^1^3C_6[/tex] = 13! / 6!(13-6)!
[tex]^1^3C_6[/tex] = 13! / 6! × 7!
[tex]^1^3C_6[/tex] =6,227,020,800 / 720×5040
[tex]^1^3C_6[/tex] =6,227,020,800 / 3,628,800
[tex]^1^3C_6[/tex] = 1,716 ways
Therefore the number of ways are 1,235,520 ways and 1,716 ways.

If earning 3250 per month over 10year period, At the end of 10th year, the amount on the account will be 390,000
What is multiplication?To multiply means to add equal groups. When we multiply, the number of things in the group increases. The two factors and the product are parts of a multiplication problem. In the multiplication problem, 6 × 9 = 54, the numbers 6 and 9 are the factors, while the number 54 is the product.
The amount earned In a month is 3250.
There are 12 months In a year.
The total month in 10 years = 10× 12 = 120 months
The total amount in the account for 10years = 120×3250 = 390,000
Therefore there will be 390000 in the account at the end of 10th year.

3y+2=2x is this a direct variation
The equation 3y + 2 = 2x is not a direct variation
How to determine if the equation is a direct variation
From the question, we have the following parameters that can be used in our computation:
Variation = direct variation
3y + 2 = 2x
A direct variation is represented as
y = kx
Where k is the constant of proportion
When the equations y = kx and 3y + 2 = 2x are compared, we can see that
The equation 3y + 2 = 2x has a constant term
Hence, the equation is not a direct variation

Stewart goes out for lunch with some of his friends. The total bill comes to
$500. The friends think that since it is Stewart’s birthday, he shouldn't have to pay. They split the cost of his lunch, with each friend paying an additional
$1
a) How many people ate dinner? Including Stewart
9514 1404 393
Answer:
0 people ate dinner
23 people ate lunch
Step-by-step explanation:
If the bill is split evenly between x people, then each pays 500/x.
Splitting the bill between x-1 people means each pays 500/(x -1).
When the difference in those amounts is 1.00, we have ...
500/(x -1) -500/x = 1
500 = x(x -1)
Completing the square gives ...
500.25 = (x -0.5)²
x = 0.5 +√500.25 ≈ 22.866 ≈ 23
Check
With 22 people splitting the $500 bill, the amount each pays is ...
$500/22 ≈ $22.73
With 23 people splitting the bill, the amount each pays is ...
$500/23 ≈ $21.74
The difference is $0.99, about $1.00. This is as close as you will get with these numbers.

(6 × 10a) + (6 × 10b) + (6 × 10c) = 6006.6
Write down a possible set of values of a, b and c.
The values of a , b and c from the equation is ( 3 , 0 , -1 )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
( 6 × 10ᵃ ) + ( 6 × 10ᵇ ) + ( 6 × 10^c ) = 6006.6 be equation (1)
Now , the number 6006.6 is written as
6000 + 6 + 0.6 = 6006.6
On simplifying the equation , we get
( 6 × 10ᵃ ) = 6000
Divide by 6 on both sides of the equation , we get
10ᵃ = 1000
So , 10ᵃ = 10³
Therefore , the value of a = 3
Now , ( 6 × 10ᵇ ) = 6
Divide by 6 on both sides of the equation , we get
10ᵇ = 1
when b = 0
10⁰ = 1
Therefore , the value of b = 0
Now , ( 6 × 10^c ) = 0.6
Divide by 6 on both sides of the equation , we get
10^c = 0.1
when c = -1
10⁻¹ = 0.1
Therefore , the value of c = -1
Hence , the value of a , b and c is 3 , 0 and -1 respectively

A figure was dilated so that the new area is 16 times bigger than the original area. Find
one possible set of perimeters for the two figures.
Please Explain!!
One possible set of perimeters for the two figures is 4x and 16x.
What is Dilation?Dilation is one of the type of transformation where the size of the object is made smaller or larger without affecting the shape.
Let A be the area of the original figure.
New area after dilation = 16A
Suppose that the figure is a square.
Area of a square is the square of it's side length and perimeter is four times the length of one side.
Let 'x' be the length of a side of the original figure.
Area of the original figure, A = x²
Perimeter of original figure = 4x
New area = 16 A = 16 x² = (4x)²
So the side length of new figure = 4x
Perimeter of new figure = 4 (4x) = 16x
Hence one of the possible set of perimeters for the two figures given is 4x and 16x.
