What’s the relationship between the number of
$4 lunches
you buy with a $100 school
lunch card and the money remaining on
the card
The relationship will be a solid line .
How to find the relationship between the given amounts?
Given:
The amount of one lunch =$4
The amount of the school lunch card=$100
Let, the amount remaining on the card= b
Let the number of lunches to buy = a
The equation is given by,
b = 100 - 4a
When 1 lunch is bought ,a= 1 ;
b= 100 - 4(1) = 96
When 2 lunches are bought ,a= 2;
b= 100 - 4 (2)= 92
When 3 lunches are bought ,a= 3;
b= 100 - 4 (3)= 88
When 4 lunches are bought ,a= 4;
b= 100 - 4 (4)= 84
Since ,the decrease is gradual and same, the relationship will be a solid line.

Please! Help me find the range of this graph as an inequality :((
Answer: [tex]\text{y} \ge 2[/tex]
Reason:
The lowest point on the graph occurs when y = 2. This is a closed endpoint so it's included with the graph. So either y = 2 or y > 2, both of which combine to get the answer shown above.
At a health camp the number of children was three times the number of men.the number of men was 240 less than the number of women. if the number of children x give an equation that can be used to get the number of men if the total number of people who attended was 2400
The equation that can be used to get the number of men if the total number of people who attended was 2400 is x + 3x + x + 240 = 2400.
How to illustrate the information?It should be noted that from the information given, in the health camp the number of children was three times the number of men and the number of men was 240 less than the number of women.
Number of men = x
Number of children = 3x
Number of women = x + 240
Total number of people = 2400
The appropriate equation will be:
x + 3x + x + 240 = 2400
5x + 240 = 2400
Collect like terms
5x = 2400 - 240
5x = 2160
Divide
x = 2160 / 5
x =432
Therefore, the total number of men is 432 men.

7-(-4) is__units from 7 in the ____ direction
7-(-4) is 4 units from 7 in the negative direction. See the explanation and the linear scale attached.
What direction is being referred to in the above Question?The direction being referred to is the direction of the number on a numerical scale or Linear Scale.
In the attached linear scale, we can see that the arrow stops at 11. This is arrived at by expanding the bracket:
7 - (-4)
the subtraction signs cancel out each other creating a positive sign. Hence we have:
7 + 4
= 11.
Hence, 11 is 4 units away from 7 in the negative direction. That is going toward zero is negative or a reduction hence, to get to 7 you need to go toward the negative section of the scale.

Consider the function f(x) = x3 − 6x2 + 11x − 6.
PART A: One factor of the function f(x) = x3 − 6x2 + 11x − 6 is (x − 3). Use that factor to divide and further factor the polynomial and find the x-intercepts without using technology.
PART B: Describe key characteristics of the graph of the function such as the number of x-intercepts, the y-intercept, and the end behavior without using technology. Explain with complete sentences using components of the function to support your answer.
For the function x³ - 6x² + 11x - 6, we have that:
a) The x-intercepts are: x = 1, x = 2, x = 3.
b) The y-intercept is of y = -6, while the end behavior is that it decreases to the left and increases to the right.
What are the x-intercepts of the function?The function is given as follows:
f(x) = x³ - 6x² + 11x - 6
x - 3 is a factor of the function, meaning that x = 3 is a x-intercept and the function can be written as follows:
x³ - 6x² + 11x - 6 = (x - 3)(ax² + bx + c)
Then we have to build a system of equations to find the coefficients as follows:
x³ - 6x² + 11x - 6 = ax³ + (b - 3a)x² + (c - 3b)x - 3c.
Then the coefficients are given as follows:
a = 1.b - 3a = -6 -> b = -3.-c = -6 -> c = 2.Then the factor is given by:
x² - 3x + 2.
Hence the other intercepts of the polynomial are found when:
x² - 3x + 2 = 0
(x - 2)(x - 1) = 0.
x - 2 = 0 -> x = 2.
x - 1 = 0 -> x = 1.
What is the y-intercept and the end behavior?The y-intercept is the value of f(x) when x = 0, that is, f(0), hence:
f(0) = 0³ - 6(0)² + 11(0) - 6 = -6.
For the end behavior, we need to find the limits as x goes to infinity, hence:
Positive infinity = (∞)³ = ∞. -> increases to right.Negative infinity = (-∞)³ = -∞. -> decreases to left.When the limit goes to infinity, we consider only the term with the highest exponent of the polynomial.

Here, ‘a’ is the vertical side i.e. wall
‘b’ is the base side i.e. bottom = 5 m
‘c’ is the hypotenuse i.e. the ladder = 10 m
If b = 5 m, c = 10 m
Then, a2 = c2 - b2 = (10 x 10) - (5 x 5) = 75

A leaky faucet drips 1/4 fluid ounce of water every 20 minutes. How many Gallons of water will leak from this faucet in 1 year? (Round to the nearest gal.)
Answer:
51
Step-by-step explanation:
I may have made a mistake somewhere along the way but if not then it is 51 gallons.
The way i did this was to multiply 20 minutes by 3 to equal an hour, then multiply that by 24 to equal a day, then multiply that by 365 to equal a year.
That gives you the numbers you need to multiply the ounce by. So first multiply 1/4 by 3 to get 3/4. Next you multiply 3/4 by 24 to get 72/4 or 18. Then you multiply 18 by 365 to get 6570 ounces in a year. Finally you translate that to gallons and you get 51.328125, which rounds down to 51.

Considering that a transversal line cuts two parallel lines, the relations between the angles are given as follows:
1. Corresponding angles.
2. Alternate exterior angles.
3. Consecutive interior angles.
What is the relationship between angles 1 and 3?Angles 1 and 3 are corresponding angles, as they are both at the same position relative to their lines, j for angle 1 and m for angle 3, being cut by the transversal line t.
What is the relationship between angles 8 and 4?Angles 4 and 8 are alternate exterior angles, as:
Angle 4 is to the left of the transversal line t and below it's line m.Angle 8 is to the right of the transversal line t and above it's line m.Inverse positions in both senses, left/right and up/down, hence alternate exterior angles.
What is the relationship between angles 2 and 3?Angles 2 and 3 form a supplementary pair inside the same region, between the two lines being cut by the transversal, hence they are consecutive interior angles.

P=1000 r=0.85% t=4 annually
Based on the given parameters, the amount of the investment after 4 years is $1030
How to determine the amount?The given parameters about the compound interest are
Principal Amount, P = $1000
Interest Rate, R = 0.85%
Time, t = 4
Number of times, n = 1 i.e. annually
Compound interests are different from simple interest, and they are calculated using the following compound interest formula
CI = P(1 + R/n)^nt - P
To calculate the amount, we have:
A = P + CI
So, the equation becomes
A = P + P(1 + R/n)^nt - P
Evaluate the like terms
A = P(1 + R/n)^nt
Substitute the known values in the above equation
A = 1000 * (1 + 0.85%/1)^(1 * 4)
Express 0.85% as decimal
A = 1000 * (1 + 0.0085/1)^(1 * 4)
Evaluate the sum
A = 1000 * (1.0085/1)^(1 * 4)
Evaluate the exponent
A = 1000 * 1.03
Evaluate the product
A = 1030
Hence, the value of the investment is $1030

Sandeep is making fruit dip for a party. His recipe calls for 1/2 of a teaspoon of cinnamon and 3/4 of a cup
of yogurt. Using this ratio, how much cinnamon does Sandeep need if he uses 3 cups of yogurt?
2 teaspoon of cinnamon need if he uses 3 cups of yogurt
What is ratio ?By comparing two amounts of the same units, the ratio can be used to calculate how much of one item is included in the other. There are two different categories for ratios. The first is a part to part ratio, whereas the second is a part to whole ratio. The relationship between two separate entities or organizations is shown by the part-to-part ratio. For instance, a class has a 12:15 boy-to-girl ratio, whereas the part-to-whole ratio describes how one group compares to another. For instance, five people enjoy reading books out of every ten persons. Since the ratio of the component to the total is 5:10, 5 out of every 10 persons enjoy reading.
Given that :Sandeep is making fruit dip for a party. His recipe calls for 1/2 of a teaspoon of cinnamon and 3/4 of a cup

The quadratic function in the standard form containing the point (-7, 5) and vertex (1, 9) is y = (-1/16)(x - 1)² + 9.
How is a quadratic function formed with a vertex and a point?The vertex form of a quadratic function with vertex (h, k) is written as
y = a(x - h)² + k, where (x, y) denotes a point on the parabola. Real integers a, h, and k are also included.
Given:
Point (x, y) = (-7, 5)
