A box of chocolates contains milk chocolates and dark chocolates in the ratio 2:3. The box contains 50 chocolates. How many milk chocolates are there in the box?
Answer:
The box contains 20 milk chocolates.
Step-by-step explanation:
Given that the chocolate box has milk chocolates and dark chocolates in a ratio of 2 milk chocolates for every 3 dark, and the total number of chocolates in the box is 50 units, to determine how many milk chocolates are in the box. it is necessary to perform the following calculation:
50 / (2 + 3)
50/5
10
Milk chocolates: 2 x 10 = 20
Dark chocolates: 3 x 10 = 30
Therefore, the box contains 20 milk chocolates.

A set of 5 consecutive integers sums to 10. What are the integers?
Answer:
Let x be the smallest integer (the first integer)
1st: x, 2nd: x + 1, 3rd: x + 2, 4th: x + 3, 5th: x + 4
Hence,
x + x + 1 + x + 2 + x + 3 + x + 4 = 10
5x + 10 = 10
5x = 0
x = 0
Therefore, the answers are
0, 1, 2, 3, 4
Step-by-step explanation:
Integers include all positive integers, negative integers and 0.
0 is an integer but it is neither positive nor negative.

Use the given data to find the best predicted value of the response variable x. Ten pairs of data yield r=0.003 and the regression equation y=2+3x, and it is determined that is not a good model. Also, the mean of y values= 5.0. What is the predicted value of y for x=2
Answer:
Step-by-step explanation:
Given the regression equation :
y=2+3x
Mean of y values ; y = 5.0
Where y is the predicted variable ; x = predictor variable
The predicted value of y for X = 2

As we know that
Diagonal of square = √2 ( side of square )So , we need to find side of square first
Using area of square = Side²
➩ 144 = S²
➩ S = √144
➩ Side = 12 cm
Now ,
➨ Diagonal = √2 ( 12 )
➨ Diagonal of square = 12√2
Distance in Feet
1. Earlier this week the famous "Live Cannonball” - Gunter Money was shot from a cannon at the Austin Expo.
Gunter flew to a height of 70 feet and traveled a distance of 160 feet only to land perfectly in a safety net.
Assume (0, 0) was the starting point for Gunter's flight and that he landed in the net at (160, 0).
(a) Use matrices to find the equation for Gunter Money's path.
(b) Write the equation for Gunter Money's path in vertex form.

Answer:
a) y = -7/640x^2 +7/4x
b) y = -7/640(x -80)^2 +70
Step-by-step explanation:
a) Given the equation in standard form:
y = ax^2 +bx +c
we can use the points (0, 0), (80, 70), and (160, 0) to find the values of a, b, c.
a·0 +b·0 +c = 0
a·80^2 +b·80 +c = 70
a·160^2 +b·160 +c = 0
The first equation tells us that c=0, so we can write a reduced matrix for the last two equations. The augmented matrix is ...
[tex]\left[\begin{array}{cc|c}6400&80&70\\25600&160&0\end{array}\right][/tex]
A matrix solver finds the solution to be ...
a = -0.0109375 = 7/640, b = 1.75 = 7/4
The standard-form equation for Money's path is ...
y = -7/640x^2 +7/4x
__
b) Factoring out -7/64, we have ...
y = -7/640(x^2 -160x)
adding and subtracting the square of the x-coefficient, we have ...
y = -7/640(x^2 -160x +6400) +70
y = -7/640(x -80)^2 +70
Simplfy [tex]8x-5+2x\frac{x}{y}[/tex]
Answer:
[tex]8x-5+2x\dfrac{x}{y}[/tex] = [tex]\dfrac{8xy-5y+2x^2}{y}[/tex]
Step-by-step explanation:
In this question, we need to simplify [tex]8x-5+2x\dfrac{x}{y}[/tex]
We can convert elements to fractions.
[tex]8x=\dfrac{8xy}{y},\:5=\dfrac{5y}{y}[/tex]
= [tex]\dfrac{8xy}{y}-\dfrac{5y}{y}+\dfrac{2x^2}{y}[/tex]
As the denominators are equal, we can combine the fractions as follows :
=[tex]\dfrac{8xy-5y+2x^2}{y}[/tex]
Hence, the simplified form is : [tex]8x-5+2x\dfrac{x}{y}[/tex] = [tex]\dfrac{8xy-5y+2x^2}{y}[/tex]
Reasoning Kareem cannot decide which of two washing machines to buy. The selling price of each is $720. The first is marked down by 50%. The second is marked down by 30% with an additional 20% off. Find the sale price of each washing machine. Use pencil and paper. Explain why Kareem should buy the first washing machine rather than the second if the machines are the same except for the selling price. The sale price of the first washing machine is $ (Round to the nearest dollar as needed.)
Answer:
store one
Step-by-step explanation:
Store One:
$720(0.50)=$360
$720-$360=$360
Store Two:
$720(0.30)=$216
$720-$216=$504
$504(0.20)=$100.8
$504-$100.8=$403.2
Angela transfers 15% of each paycheck she received into her savings account. If she transferred $54 into her savings account last week, how much did she earn on that paycheck? Show your work using a model, proportion or equation.
Answer:
She earned $360 on that paycheck.
Step-by-step explanation:
From the information given, you know that Angela transfers 15% of each paycheck and that she transferred $54 last week. With this, you can say that the amount she earned multiply for 15% is equal to 54, which you can express with the following equation:
0.15x=54, where x is the amount she earned on that paycheck.
Now, you can solve for x:
x=54/0.15
x=360
According to this, the answer is that she earned $360 on that paycheck.

Step-by-step explanation:
Since AD bisects BC,
BD = DC.
Therefore 5x - 10 = 3x + 10 and x = 10.
Answer:
The value of x is 10.
Step-by-step explanation:
BD =CD
Which means
5x - 10 = 3x + 10
Let's solve.
[tex]5x - 10 = 3x + 10 \\ \frac{ - 3x \: \: \: \: \: = - 3x \: \: \: \: \: }{2x - 10 = 10} \\ \\ 2x - 10 = 10 \\ \frac{ \: \: \: \: \: \: \: \: \: + 10 = + 10}{2x = 20} \\ \\ \frac{2x}{2} = \frac{20}{2} \\ \\ x = 10[/tex]
Therefore, x = 10.

The coordinate of centroid of a triangle whose vertices are (1,3,-2), (4,5,0), (6,3,9) is = ……………….
Answer:
[tex]C = (\frac{11}{3},\frac{11}{3},\frac{7}{3})[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1,z_1) = (1,3,-2)[/tex]
[tex](x_2,y_2,z_2) = (4,5,0)[/tex]
[tex](x_3,y_3,z_3) = (6,3,9)[/tex]
Required
Determine the coordinates of the centroid
Represent the coordinates with C.
C is calculated as follows:
[tex]C = (\frac{1}{3}(x_1+x_2+x_3),\frac{1}{3}(y_1+y_2+y_3),\frac{1}{3}(z_1+z_2+z_3}))[/tex]
Substitute values of x and y in the given equation
[tex]C = (\frac{1}{3}(1+4+6),\frac{1}{3}(3+5+3),\frac{1}{3}(-2+0+9}))[/tex]
[tex]C = (\frac{1}{3}(11),\frac{1}{3}(11),\frac{1}{3}(7}))[/tex]
[tex]C = (\frac{11}{3},\frac{11}{3},\frac{7}{3})[/tex]
The above is the coordinate of the centroid
the perimeter of a rectangle is (8x + 7y) feet, give two possible dimensions of the rectangle
please help ??
Answer:
Two possible dimensions of the rectangle are 4x and 7/2 y.
Step-by-step explanation:
The Perimeter of a Rectangle
It's given the perimeter of a rectangle is
P = 8x + 7y
The formula to calculate the perimeter of a rectangle of dimensions L and W is:
P = 2W + 2L
Equating term by term, we can guess two possible dimensions of the rectangle:
2W = 8x
Dividing by 2:
W = 4x
And also:
2L = 7y
Dividing by 2:
L = 7/2 y
Thus, two possible dimensions of the rectangle are 4x and 7/2 y.
write and equation of the line below
Answer:
y = 1/4x + 0 or just y = 1/4x
