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.

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]
Fine the volume for the shape below:

give an example of what hi numbers could be ?
9514 1404 393
Answer:
-2, 3
Step-by-step explanation:
For the product to be negative, exactly one of the two numbers must be negative. For the sum to be positive, the positive number must be larger than the absolute value of the negative number.
One such pair of numbers is -2 and 3.
__
Their product is -6; their sum is +1.
What is a remainder
A remainder is the remaining amount of a number than comes out of a division. I'm not sure how to explain it better, so I'll give you an example:
Let's say you want to divide 5 by 2. We know that 5 can't be divided by 2 evenly, it won't give you a whole number. Instead it will give you a decimal 2.5.
In this case, 1 is the remainder and I will explain why! Do the long division for 5/2. 2 fits into 5 two times, so you multiply 2 * 2, which gives you 4. If you subtract that number from 5, you get 1. We know that 2 can't fit into one, therefore, 1 is the remainder. once you start getting into decimals, you can fit numbers into other numbers, which is why technically you can fit 2 into 5, but you can't fit it in evenly, if that makes sense!
I hope this example helps see what a remainder is. It's just the number in a long division that the divisor (in my example, 2 is the divisor) can't fit in!

(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

The weight of the square is 10 grams. How much heavier is the circle than the square?
The weight of the circle is heavier than the weight of the square by the weight of the triangle
How to find how much weightier is the circle as compared with the squareExamining the weights, can lead to a linear equation, the equation will have the follows parameters
let t represent triangle
let c represent circle
let s represent square
6s + 3t = 3s + 3c
6s - 3s + 3t = 3s + 3c
3s + 3t = 3c
divide through by 3
s + t = c
10 + t = c
From the equation 10 + t = c we can say that the weight of the circle is a triangle weight more than the square

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

LMNP is a rectangle. Find the value of x and the length of each diagonal.
The value of x is equal to 3.
The length of diagonal LN is equal to 18 units.
The length of diagonal MP is equal to 15 units.
What is a diagonal?In Mathematics, the diagonal of a rectangle can be defined as a line segment that connects any two (2) of its non-adjacent vertices together while dividing the rectangle into two (2) equal parts.
This ultimately implies that, the length of each diagonal of a rectangle is always equal to each other. Therefore, the diagonals of any rectangle is always equal to one other.
How to determine the value of x?We would determine the value of x by equating the length of each diagonal as follows;
LN = MP
7x - 3 = 4x + 3.
7x - 4x = 3 + 3
3x = 6
x = 6/2
x = 3.
Next, we would calculate length of each diagonal as follows;
LN = 7x - 3
LN = 7(3) - 3
LN = 21 - 3
LN = 18 units.
MP = 4x + 3.
MP = 4(3) + 3.
MP = 12 + 3
MP = 15 units.

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
