At Burger Haven, 11 of the last 44 customers wanted cheese on their burgers. Considering this data, how many of the next 256 customers would you expect to want cheese?
Answer:
64
Step-by-step explanation:
11 out of 44 = 25%
11 ÷ 44 = 0.25 = 25%
25% × 256 = 64
a) Complete the table of values for y = x2 + x - 4

y
Answer:
The values of y for each value of x are:
[tex]x = -3, y =2[/tex]
[tex]x = -2\: , y =-2[/tex]
[tex]x = -1\: , y =-4[/tex].
[tex]x = 0\: , y =-4[/tex]
[tex]x = 1\: , y = -2[/tex].
[tex]x = 2\: , y =2[/tex]
[tex]x = 3\: , y = 8[/tex]
Step-by-step explanation:
We have all the values of x, they are from -3 to 3 passing for 0.
Now, we know that y is a quadratic function (y=x²+x+4)
Therefore, we just need to put each value of x into the quadratic equation to find each y value.
When:
[tex]x = -3, y = (-3)^2+(-3)-4=2[/tex]
[tex]x = -3\: , y = 2[/tex]
We can do this for all values of x, so we will have:
[tex]x = -2\: , y = (-2)^2+(-2)-4=-2[/tex]
[tex]x = -1\: , y = (-1)^2+(-1)-4=-4[/tex].
[tex]x = 0\: , y = (0)^2+(0)-4=-4[/tex]
[tex]x = 1\: , y = (1)^2+(1)-4=-2[/tex].
[tex]x = 2\: , y = (2)^2+(2)-4=2[/tex]
[tex]x = 3\: , y = (3)^2+(3)-4=8[/tex]

The two trapezoids below are similar. What is the length of EF?
Answer:
x/24 = 7.5/30
30x = 180
________
30
x= 6
The length of EF in given trapezoid is 6 cm
What is trapezoids ?Trapezoids are quadrilaterals that have two parallel sides and two non-parallel sides. It is also called a Trapezium. A trapezoid is a four-sided closed shape.
a pair of opposite sides are parallel.
diagonals of trapezium bisect each other.
sum of all four angles of trapezium is = 360°
it has four unequal sides.
diagonals are congruent.
opposite side of an isosceles trapezium are congruent.
According to the question
Trapezoids ABCD and EFGH are similar,
Hence, corresponding sides ratio are equal
Thus, AB/EF = DC/HG
24/x = 30/7.5
30x = 180
x = 180/30
x= 6
Hence, The length of EF is 6 cm

Emily works at a perfumery. She extracts 3 liters of essential oil for perfumes in 2 days.
Assuming Emily extracts essential oil at a constant rate, we can graph this relationship with time in days along the x-axis and quantity of oil in liters along the y-axis. The slope of the line representing this relationship is
.
A point on this line that corresponds to the amount of oil Emily extracts after 5 days is (5,

what fraction is greater than 1/5 and less than 1/3
The fraction 1/4 is greater than 1/5 and less than 1/3
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction that can be written as the form of p : q, which is equivalent to p / q.
We need to find the fraction that is greater than 1/5 and less than 1/3
Since we know that 1/5 < 1/4 < 1/3
When the numerator is less than the denominator, the fraction is called proper fraction, otherwise it is called improper fraction that proper fraction is also called fraction which is less than 1.
Therefore the answer is; 1/4

Evan bought a bag of Skittles, ate 13 of them, then distributed them evenly into 4 bowls. If there are 64 Skittles in each bowl, how many were originally in the bag?
For the problem, find a variable and set up an equation, then solve.
I need this answer quick!
Answer:
There were 269 skittles in the bag originally.
Keywords: multiplication, addition
Step-by-step explanation:
Skittles ate by Evan = 13
No. of bowls = 4
No. of skittles in each bowl = 64
As the skittles are distributed evenly therefore,
Skittles in 4 bowls = 64*4
Skittles in 4 bowls = 256
Total skittles = Skittles in 4 bowls + skittles ate by Evan
Total skittles = 256 + 13
Total skittles = 269
There were 269 skittles in the bag originally.

15 - 3x = 11 - 3x + 4
Answer:
Infinitely Many Solutions!
Steps I used to get the answer :
1. Cancel -3x−3x on both sides.
15=11+4
2. Simplify 11+4 to 15.
15=15
3. Since both sides equal, there are infinitely many solutions.
Infinitely Many Solutions!
Done by NeighborhoodDealer.
Answer:
Step-by-step explanation:
Solve for x:
15 - 3x = 11 - 3x + 4
Subtract 4 from both sides
15 - 3x - 4 = 11 - 3x + 4 - 4
11 - 3x = 11 - 3x
This equation has infinite solutions since both sides of the equation are equal.
