What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, A train in France can travel at a speed of 217.4 miles per hour.
A train in China can travel 1.23 times this speed to obtain the speed of the train in china we have to multiply how many times it is faster by the speed of the train in France which is,
= (217.4× 1.23) miles per hour.
= 267.4 miles per hour.

If b⊥c and b⊥d, then c ? d
Answer:
C and D are parallel
Step-by-step explanation:
If b⊥c and b⊥d, then that means that they are both parallel because they both have a 90 degree anglewith line B.
Answer:
| | (Parallel)
Step-by-step explanation:
I'm assuming that is what it is asking. if b and c are perpendicular, that means they form 90 degrees on all angles. The same for b and d. So if both c and d are perpendicular to b, then they are parallel.

A student takes 1.5 hours to complete her midterm. How many seconds did it take her to finish the assessment?
The student took 5400 seconds to finish her assessment.
Given,
A student takes 1.5 hours to complete her midterm.
We have to find how many seconds it took to finish her midterm assessment.
How many seconds in an minute?One hour = 60 minutes
1 minute = 60 seconds
We have,
A student takes 1.5 hours to complete her midterm.
1.5 hours = to complete the assessment.
Converting 1.5 hours into seconds.
1 minutes = 60 seconds
Multiplying 60 on both sides.
60 x 1 minutes = 60 x 60 seconds
60 minutes = 3600 seconds
1 hour = 60 minutes
1 hour = 3600 seconds
Multiplying 1.5 on both sides.
1.5 x 1 hour = 1.5 x 3600 seconds
1.5 hours = 5400 seconds.
Thus the student took 5400 seconds to finish her assessment.

What is the image of the point (2,3) after the transformation Ry-axis?
Answer:
The image of the point (2, 3) after the reflection across the y-axis will be: (-2, 3)
Step-by-step explanation:
We know that when a point, let say P(x, y), is reflected across the y-axis, the sign of x-coordinate is reversed but y-coordinate remains the same.
In other words, the rule is:
P(x, y) → P'(-x, y)
Here, P'(x, y) is the image of the original point P(x, y) after the reflection across the y-axis.
Considering the point
A(2, 3)Let us reflect the point A(2, 3) across the y-axis.
We know the rule:
P(x, y) → P'(-x, y)
so
A(2, 3) → A'(-2, 3)
Thus, the image of the point (2, 3) after the reflection across the y-axis will be: (-2, 3)

write and solve this equation: Samantha is one year less than twice her brother Jack’s age. If the sum of their ages is 41, how old is Samantha?
Answer:
Samantha's age = 27 years
Step-by-step explanation:
Let Jack's age be = xAs Samantha is one year less than twice her brother Jack’s age.
So Samantha's age = 2x-1As the sum of their ages is 41.
Thus, the equation become
x+2x-1 = 41
3x-1 = 41
3x = 42
Dividing both sides by 3
x = 14
It indicates that Jack's age = 14 years
Therefore,
Samantha's age = 2x-1 = 2(14)-1 = 27 years

Answer:
1 m²Step-by-step explanation:
The first man painted:
x + 20The second man painted:
x + 6If the first man painted 3 times more, then:
x + 20 = 3(x + 6)x + 20 = 3x + 183x - x = 20 - 182x = 2x = 1Solve the system of equations by substitution. What is the solution for x? (1 point)

the mean number of emails adele received during a week was 51.
The numbers received for the six days were 39, 57, 70, 45, 71, 32.Find how many emails she received on the seventh day.
Given:
The mean number of emails adele received during a week was 51.
The numbers received for the six days were 39, 57, 70, 45, 71, 32.
To find:
The number of emails received on the seventh day.
Solution:
Let x be the number of emails received on the seventh day.
We know that,
[tex]\text{Mean}=\dfrac{\text{Sum of observations}}{\text{Number of observations}}[/tex]
[tex]51=\dfrac{314+x}{7}[/tex]
Multiply both sides by 7.
[tex]357=314+x[/tex]
Subtract 314 from both sides.
[tex]357-314=x[/tex]
[tex]43=x[/tex]
Therefore, she received 43 emails on the seventh day.

Item 1: sleeved dress $17.99
Item 2: skirt $16.19
Item 3: t shirt $8.99
Subtotal is $43.17
Discount the cheapest item 30% off. Subtract subtotal-discount for sale price. Tax is 3.5% add sale price + tax what is the final with tax?
Answer:
The final price including tax is $41.89
Step-by-step explanation:
The following items are on sale:
Sleeved dress $17.99
Skirt $16.19
T-shirt $8.99
Subtotal $43.17
The cheapest item is the T-shirt for $8.99 and it will be discounted by 30%:
$8.99 - 30/100 * $8.99 = $8.99 - $2.70 = $6.29
The total sale price is now: $43.17-$2.70=$40.47
Now we add the 3.5% tax:
$40.47 + 3.5/100 * $40.47 = $40.47 + $1.42 = $41.89
The final price including tax is $41.89
