A toy factory creates handmade train sets. One train car takes 0.4 hours to construct and 0.6 hours to paint. A section of wooden track requires 0.2 hours to construct and 0.1 hours to paint. A full train set with x train cars and y sections of wooden track takes 5.2 hours to construct and 4.2 hours to paint. Which system of equations can be used to find the number of train cars and number of sections of wooden track in a full train set?
To find the number of train cars and sections of wooden track in a full train set, we can set up a system of equations. The equations are 0.4x + 0.2y = 5.2 and 0.6x + 0.1y = 4.2.
Explanation:To find the number of train cars and number of sections of wooden track in a full train set, we can set up a system of equations based on the given information.
Let's use x to represent the number of train cars and y to represent the number of sections of wooden track.
The time to construct 1 train car is 0.4 hours, so the time to construct x train cars is 0.4x hours.The time to paint 1 train car is 0.6 hours, so the time to paint x train cars is 0.6x hours.The time to construct 1 section of wooden track is 0.2 hours, so the time to construct y sections of wooden track is 0.2y hours.The time to paint 1 section of wooden track is 0.1 hours, so the time to paint y sections of wooden track is 0.1y hours.The total time to construct a full train set is 5.2 hours, so we have the equation 0.4x + 0.2y = 5.2.The total time to paint a full train set is 4.2 hours, so we have the equation 0.6x + 0.1y = 4.2.The system of equations that can be used to find the number of train cars and number of sections of wooden track in a full train set is:
0.4x + 0.2y = 5.2
0.6x + 0.1y = 4.2

What is the value in dollars of a stack of dimes that is 10 cm high? (1mm = 1 dime?
The value in dollars of a stack of dimes that is 10 cm high is $10.
What are nickles, dimes, quarters and cents?A dollar is further divided into some majorly used parts as:
A cent = 100th part of a dollar = $1/100 = $0.01
A nickle= 20th part of a dollar = $1/20 = $0.05
A dime = 10th part of a dollar = $1/10 = $0.10
A quarter = 4th part of a dollar = $1/4 = $0.25
If each dime is 1 mm then 10 dimes will be 1 cm high;
1 dime / 1 mm = x dimes / 10 mm Cross multiply
1 dime * 10 mm = x * 1 mm
10 dimes = x The mm
Since a dime is about 1 mm thick (10mm equals 1 cm), 10 cm high would be 100 dimes;
10 dimes = $1
$1 times 10 = $10
Hence, The value in dollars of a stack of dimes that is 10 cm high is $10.

does anyone understand how to do this? Solve r4<−5 or −2r−7 ≤ 3 . The solution is _or_
The given problem consists of solving two inequalities. The first one, r4<−5, is invalid since the 4th power of any real number cannot be a negative number. For the second inequality, −2r−7 ≤ 3, the solution is r ≥ -5.
Explanation:The subject of this question is Mathematics, specifically relating to solving inequalities. To answer your question, let's solve the two given inequalities independently. Starting with the first one, r4<−5, this inequality is invalid as the 4th power of any real number (r) cannot be less than -5. Moving on to the second inequality, −2r−7 ≤ 3, we first add 7 to both sides to isolate the term with the variable, giving us -2r ≤ 10. Dividing both sides by -2 (remember to flip the inequality sign when multiplying or dividing by a negative number) gives us r ≥ -5. Therefore, the solution to the given inequalities is r ≥ -5.

Find the slope of the line that passes through the pair of points.
Answer:
Option B is correct
Slope of the lines that passes through the given points is, [tex]\frac{-6}{5}[/tex]
Step-by-step explanation:
Given: The points (2 , 6) and (7 ,0).
Slope of a line identify the direction of a line. To find the slope, you divide the difference of the y-coordinates of two points on a line by the difference of the x- coordinates of those same two points.
For any two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] the slope(m) of a line is given by;
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
Now, substitute the point (2 ,6 ) and ( 7, 0) in the slope formula we have;
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}=\frac{0 - 6}{7-2}[/tex] = [tex]\frac{-6}{5}[/tex]
therefore, the slope of the line that passes through the pair of points is; [tex]\frac{-6}{5}[/tex]
whats the area of a cardboard In one carton if the length is 9 inches height is 9inches width is 4 inches and is 240 ml as well as also in a 946 ml container and a 1.89 L container?
Assuming that the cardboard forms a regular rectangle, therefore the area of the cardboard is simply taken to be the product of length and width. Therefore:
A = l w
A = (9 inches) * (4 inches)
A = 36 square inches = 36 inches^2

Suppose Mrs. Reyes would like to save Php 1,000.00 at the end of each month for 9 months in a fund that gives 5% per annum compounded monthly. How much would the value of her savings be after 7 months?
After 7 months her savings will be 7117.64.
Step-by-step explanation:
Given :
Rate is r = 5% = 0.05
Compounding interval, n = 12
Solution :
Now,
[tex]\rm \dfrac{r}{n} = \dfarc{0.05}{12}[/tex]
[tex]\rm \dfrac{r}{n} = 0.004167[/tex]
Now first deposit duration is 7 months. Therefore, its value is [tex]\rm a_1 = 1000\times (1.004167)^7[/tex]
Now second deposit duration is 6 months. Therefore, its value is
[tex]\rm a_2 = 1000\times (1.004167)^6[/tex]
Now third deposit duration is 5 months. Therefore, its value is
[tex]\rm a_3 = 1000\times (1.004167)^5[/tex]
and so on.
The values are in geometric sequence where
[tex]\rm a = 1000\times (1.004167)[/tex]
[tex]\rm r = 1.004167[/tex]
We know that the sum of the geometric sequence is given by,
[tex]\rm S_n = \dfrac{a (r^n-1)}{(r-1)}[/tex] ------ (1)
Now put the values of a and r in equation (1),
[tex]\rm S_7=\dfrac{1000\times(1.004167)((1.004167)^7-1)}{(1.004167-1)}[/tex]
[tex]\rm S_7 = 7117.64[/tex]
After 7 months her savings will be 7117.64.

Because and form a circle, and a circle measures 360°, the measure of is 360 – a°. Because of the ________ theorem, m∠A = degrees and m∠C = degrees. The sum of the measures of angles A and C is degrees, which is equal to , or 180°. Therefore, angles A and C are supplementary because their measures add up to 180°. Angles B and D are supplementary because the sum of the measures of the angles in a quadrilateral is 360°. m∠A + m∠C + m∠B + m∠D = 360°, and using substitution, 180° + m∠B + m∠D = 360°, so m∠B + m∠D = 180°. What is the missing information in the paragraph proof?
Quadrilateral ABCD is inscribed in a circle. Let the measure of arc BAD be a°. Arcs BCD and BAD form a circle and a circle measures 360°, then measure of arc BCD is 360°-a°.
The inscribed angle theorem states that an angle inscribed in a circle is half of the central angle that subtends the same arc on the circle.
Because of the Inscribed angle theorem,
[tex]m\angle A=\dfrac{a^{\circ}}{2};[/tex]
[tex]m\angle C=\dfrac{360^{\circ}-a^{\circ}}{2}.[/tex]
The sum of the measures of angles A and C is
[tex]\dfrac{a^{\circ}}{2}+\dfrac{360^{\circ}-a^{\circ}}{2}=180^{\circ}.[/tex]
Therefore, angles A and C are supplementary, because their measures add up to 180°.
Angles B and D are supplementary, because the sum of the measures of the angles in a quadrilateral is 360°.
m∠A + m∠C + m∠B + m∠D = 360°,
and using substitution,
180° + m∠B + m∠D = 360°, so m∠B + m∠D = 180°.

Solve x2 = 144
Select one:
a. 72
b. 12
c. ±12
d. −12
So I chose B which I thought was correct but it was wrong
Power is the result of multiplying two numbers together. The solution of the x²=144 is ±12. The correct option is C.
What is power?Power is the result of multiplying two numbers together such that both numbers are equal to each other. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.
The solution of the given expression can be written as,
x² = 144
x² = 12×12 or -12×-12
x = √(12×12) or √(-12×-12)
x = 12 or -12
x = ±12
Thus, the solution of the x²=144 is ±12. This is because the multiplication of two positive numbers is positive, also, the sum of the two negative numbers is positive.
Hence, the solution of the x²=144 is ±12
