a family of six goes to the local sandwich shop. all six people order the combination meal, which includes a drink and a sandwich for 6.99. one person thinks the total bill for the family of six will be around 30.00.
is this a reasonable estimate?
Answer:
No it wouldn’t be
Step-by-step explanation:
Well lets say the cost of 6.99 is rounded up to 7 since its a penny short.
There are 6 people and 6*7=42
So the answer would be about 42 dollars which is 12 dollars off.
Even if we round down the 6.99 to 6 it would still be 6 dollars off and thats still a low estimate

Answer:
it's D
Step-by-step explanation:
4x represents the hours and A, B, and C doesn't make sense especially c because it has a -4 so the correct answer is D I'm sure
Answer:
Choice D y = 4x -12
Step-by-step explanation:
Since Kevin owes his brother $12, we can clarify that b=-12. He also has a babysitting job where he receives $4 an hour which we can express as 4x; let x represent the amount of hours he works.
The graph equation is y=mx + b
so, y = 4x -12

The measure of angle ABC is 132°.
The total measure of ABC and BCD is 180° because it is a straight angle.
If BCD is 48°, they ABC is 132°. You get this because you subtract 180° by 48°.

The number of students who bring lunch is 45 fewer these the number of students who eat the school lunch. There are more than 485 students who bring lunch. Write an inequality to find the possible number of students,n, who eat the lunch
Answer:
83
Step-by-step explanation:
there is many ways to do it!! HOPE YOU ACE IT
The number of students, n that possibly eat lunch at school, n = 531 or more students.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that the number of students who bring lunch is 45 fewer these the number of students who eat the school lunch. There are more than 485 students who bring lunch.
The number of students who bring lunch, is;
B > 485 students
The number of student who eat lunch in school, E = B + 45
Thus, E > 485 + 45
The number of student that possibly eat lunch in school, E > 530 students.
The number of students, n that possibly eat lunch at school, n = 531 or more students.

General Formulas and Concepts:
Algebra
Expand by FOIL (First Outside Inside Last)Terms/Coefficients/DegreesStep-by-step explanation:
Step 1: Define
f(x) = -6x + 11
g(x) = 3x - 5
(f * g)(x) is f(x) · g(x)
Step 2: Find
Substitute: (f * g)(x) = (-6x + 11)(3x - 5)Expand [FOIL]: (f * g)(x) = -18x² + 30x + 33x - 55Combine like terms: (f * g)(x) = -18x² + 63x - 552(x-5)=10 but the pemdas is backwards

Answer:
3. The vertex form of the function, f(x) = x² - 4·x - 17 is f(x) = (x - 2)² - 21
4. The solutions are, x = -2 + √10 and x = -2 - √10
5. The quadratic equation with vertex (3, 1) and a = 1 in standard form is given as follows;
f(x) = x² - 6·x + 10
Step-by-step explanation:
3. The function given in standard form is f(x) = x² - 4·x - 17, which is the form, f(x) = a·x² + b·x + c
The vertex form of the of a quadratic function can be presented based on the above standard form as follows;
f(x) = a(x - h)² + k
Where;
(h, k) = The coordinate of the vertex
h = -b/2a
k = f(h)
Comparing with the given equation, we have;
f(x) = a·x² + b·x + c = x² - 4·x - 17
a = 1
b = -4
c = -17
∴ h = -(-4)/(2 × 1) = 2
h = 2
k = f(h) = f(2) = 2² - 4 × 2 - 17 = -21
k = -21
The vertex form of the function, f(x) = x² - 4·x - 17 is therefore, given as follows;
f(x) = (x - 2)² - 21
4. The given equation for which we need to solve by completing the square is 2·x² + 8·x = 12
Dividing the given equation by 2 gives;
x² + 4·x = 6
Which is of the form, x² + b·x = c
Where;
a = 1
b = 4
c = 6
From which we add (b/2)² to both sides to get x² + b·x + (b/2)² = c + (b/2)²
Adding (b/2)² = (4/2)² to both sides of x² + 4·x = 6 gives;
x² + 4·x + 4 = 6 + 4
(x + 2)² = 10
x + 2 = ±√10
x = -2 ± √10
The solution are, x = -2 + √10 and x = -2 - √10
5. Given that the value of the vertex = (3, 1), and a = 1, we have;
The vertex, (h, k) = (3, 1)
h = 3, k = 1
Therefore, h = 3 = -b/(2 × a) = -b/(2 × 1)
∴ -b = 2 × 3 = 6
b = -6
k = f(h) = a·h² + b·h + c, by substitution, we have;
k = f(3) = 1 × 3² + (-6) × 3 + c = 1
∴ c = 1 - (1 × 3² + (-6) × 3) = 10
c = 10
The quadratic equation with vertex (3, 1) and a = 1 in standard form, f(x) a·x² + b·x + c is therefor;
f(x) = x² - 6·x + 10
Instructions: Find the missing side. Round your answer to the nearest tenth.
Answer:
x ≈ 74.3
Step-by-step explanation:
Using the tangent ratio in the right triangle, that is
tan22° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{30}{x}[/tex] ( multiply both sides by x )
x × tan22° = 30 ( divide both sides by tan22° )
x = [tex]\frac{30}{tan22}[/tex] ≈ 74.3 ( to the nearest tenth )

Kasey is trying to run a certain number of miles by the end of the month. If Kasey is 60% of the way to achieving her goal and she has already run 24 miles, how many miles is she trying to run by the end of the month?
Answer:
40 miles
Step-by-step explanation:
Step one:
given data
let the total distance to be covered by Kasey by the end of the month be x
Required is x
so
60% of x= 24
60/100*x= 24
0.6x= 24
divide both sides by 0.6
x= 24/0.6
x=40 miles
What is the value of N?
Answer:
85
Step-by-step explanation:
Since the exterior angles of a triangle always add up to 360:
360 - 133 - 142 = 85
Step-by-step explanation:
all 3 indicated angles are outside angles of a triangle.
the sum of all outside angles of any polygon is 360°.
so,
N = 360 - 133 - 142 = 85°
