if 6 burgers cost $7.74 how many can you buy for $19.35
Answer:
15 burgers!
Step-by-step explanation:
The trick is to get rid of the decimal point from the number we are dividing by.
How? We can "shift the decimal point" out of the way by multiplying by 10, as many times as we need to.
But we must do the same thing to both numbers in the division.
Example: 15 divided by 0.2
Let us multiply the 0.2 by 10, which shifts the decimal point out of the way:
0.2 × 10 = 2
But we must also do it to the 15:
15 × 10 = 150
So 15 ÷ 0.2 has become 150 ÷ 2 (they are both 10 times larger):
150 ÷ 2 = 75
And so the answer is:
15 ÷ 0.2 = 75
De un listón que compró Constanza para decorar su salón que medía tres metros y un tercio grato ocho sextos que cantidad de listón le quedó
Answer:
1.33 meters
Step-by-step explanation:
La cinta mide 3 metros de largo. Cuando Constanza utilizó la cinta ocho por sexta, la cinta que le queda será una por tres. La ecuación será la siguiente:
3 meters - 1/3 meters - 8 / 6 meters
4 / 3 meters = 1.33 meters.
Write the equation in standard form of the quadratic that has a root of (3,0) and a vertex at (1,-4), then list out the values of a,b and c.
Answer:
a = 1, b = -2, c = -3
Step-by-step explanation:
The equation in factored form shows the roots with the "r" and "s" variables. Note that they are written negative "r" and negative "s" in the formula.
y = a(x - r)(x - s)
The vertex is always halfway between the two roots.
<------[root]--------[vertex]--------[root]---->
The vertex is at x = 1, and one root is at x = 3. The other root is at x = -1.
Write the equation in factored form to show the two roots.
y = a(x - 3)(x + 1)
Substitute the vertex (1, -4) into the equation. The point is written (x, y).
-4 = a(1 - 3)(1 + 1)
Solve for "a".
-4 = a(-2)(2) Simplify within the brackets
-4 = -4a Multiply -2 and 2. Divide both sides by -4
a = 1 Solved for "a" (and kept the variable on the left side).
Substitute a = 1 back into the formula.
y = a(x - 3)(x + 1)
y = 1(x - 3)(x + 1)
We don't have to write multiplied by 1 though, because anything multiplied by 1 is itself.
y = (x - 3)(x + 1)
Since we are looking for "a", "b", and "c", find the equation in standard form.
y = ax² + bx + c
To change factored form into standard form, expand the brackets.
y = (x - 3)(x + 1)
y = x² + x - 3x - 3
y = x² - 2x - 3
Compare the expanded equation to y = ax² + bx + c
∴ a = 1, b = -2, c = -3

A manager is considering three new machines for filling boxes of cereal at a processing plant. Each of the three machines is assigned to 10 randomly selected employees. The time required to fill 25 boxes using the machine is recorded. How many treatments does this single-factor experiment have
Answer:
3
Step-by-step explanation:
Given that :
Number of machines which are asre assigned 10 different randomly selected employees = 3
Hence, the number of treatments in the single - factor experiment is 3. This is because from the knowledge of ANOVA(Analysis of Variance), the letter 'k' is used to depict the number of treatment which is equivalent to the number of independent groups which we want to experiment or compare. Since each of the 3 new machines are treated independently. Hence, we have 3 treatments.
Also the number of groups k which are assigned the same Number of sample sizes in the comparison group is the Number of treatments on the analysis.
Hence, 3 different groups are each assigned 10 random employees. Then the number of treatments equals 3.
Find the x and y intercepts of the graph of
the equation 11x + 2y = 44. Find the
intercepts algebraically and show your
work on your work paper.
Answer:
x-intercept : 4
y-intercept : 22
Step-by-step explanation:
The equation is given as ;
11x + 2y = 44
write the equation in form of y= mx + c where c is the y-intercept and m is the gradient.
11x + 2y = 44
2y =-11x + 44 ----divide each term by 2 as;
y= -11/2 x + 44/2
y= -5.5 x + 22 ------equation of the graph
y-intercept is 22
x- intercept is the value of x when y=0
y= -5.5 x + 22
0 = -5.5 x + 22
5.5 x = 22
x = 22/ 5.5

Exponential Decay Function
The exponential function is used to model natural decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The element has an initial mass of Mo=970 grams, the decaying rate is r=27.7% = 0.277 per minute.
The equation of the model is:
[tex]M(t)=M_o\cdot(1-r)^t[/tex]
[tex]M(t)=970\cdot(1-0.277)^t[/tex]
Operating:
[tex]M(t)=970\cdot 0.723^t[/tex]
After t=13 minutes the remaining mass is:
[tex]M(13)=970\cdot 0.723^{13}[/tex]
Calculating:
M(13)=14.3 gram
