The area of a rectangular field is 48m2 and one of its sides is 6m . How long will a lady take to cross the field diagonally at the rate of 20m/min
Answers
Answer:
It will take her approximately 28 seconds to cross the diagonal of the pitch
Step-by-step explanation:
If we can find the length of the diameter of the field (in Metres), we can easily find the time it takes her to cross this length using motion equations.
Step one: Find the length of the field from its area.
The field is rectangular in shape. The area of the field is 48m^2. To get the area of the field, we had to multiply its length and its breadth.
i.e area = length X breadth.
Let us assume that the breadth = 6m
its length will be area / breadth = 42/ 6 = 7m
The length of the pitch = 7 m
Step Two: Find the length of the diagonal using Pythagoras' theorem.
From Pythagoras'theorem, the length of the diagonal can be obtained by
[tex]diagonal = \sqrt{l^2 +b^2}[/tex]
[tex]diagonal = \sqrt{6^2+ 7^2} = 9.22m[/tex]
The length of the diagonal is 9.22m
Step three: Find the time using her speed and the distance she needs to cover.
Time = distance / speed
time = 9.22 /20 = 0.46 minutes
It will take her approximately 28 seconds to cross the diagonal of the pitch

A car and a motorcycle leave the city at the same time and drive to a lake that is 120 km away. The speed of the motorcycle is 20 km per hour greater than the speed of the car, so the motorcycle arrives at the lake 1 hour before the car. Find the speed of the car and the speed of the motorcycle. Plz answer fast!!
Answers
Answer:
40 km/h and 60 km/hStep-by-step explanation:
Let the speed of the car is x, then the speed of motorcycle is x + 20
The distance = 120 km
Time:
120/x = 120/(x + 20) + 1120(x + 20) = 120x + x(x +20)120x + 2400 = 120x + x² + 20xx² + 20x = 2400 x² + 2*10x + 10² = 2500(x + 10)² = 50²x + 10 = 50x = 40Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h
Answer:
Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h

What is the slope of y = -5 + 42?
Answers
your welcome
Answer:
slope should be -5
Step-by-step explanation:
the equation is y=-5+42
slope equation form is y=mx+b
m is the slope in the equation, b is the y-intercept(where it hits the line if graphed)
so b should be 42 and slope should be -5

As, we have :

[tex] \\ [/tex]
[tex] \tt : \implies Students \: present \: on \: Monday = \dfrac{5}{7} \times 35[/tex]
[tex] \tt : \implies Students \: present \: on \: Monday = \dfrac{5}{\cancel{7}} \times \cancel{35}[/tex]

Now, we have to find students not present on Monday :
As, we have :
Total number of students = 35 Students present on Monday = 25[tex] \\ [/tex]
Therefore,
Students absent on Monday = 35 - 25 = 10

If you need to make $678 and it costs $28 to make it and you are selling it for $40 each .. What is the minimum you have to sell
Answers
Complete question :
Mitch is making birdhouses to sell. He needs to make at least $678. Each birdhouse costs $28 to make. He is selling them for $40 each. What is the minimum he can sell to reach his goal?
Answer:
57
Step-by-step explanation:
you need to make $678 and it costs $28 to make it and you are selling it for $40 each .. What is the minimum you have to sell
Target profit = $678
Expenses per product = $28
Income per sale = $40
Profit per sale = $(40 - 28) = $12
Let number of sales or product = x
Hence,
$12 * x ≥ 678
12x ≥ 678
x ≥ 678 / 12
x ≥ 56.5
To the nearest whole number = 57

Consider that lines u and vare parallel. Which equation models the relationship between the angles? What is the value of x?
Answers
[tex]\color{plum}\tt \: \bold{(A) 12x - 4 = 10x + 10 ; x = 7}[/tex]
Steps to derive the correct option :Given :Lines u and v are parallel Measure of an angle = 12x - 4Measure of it's corresponding angle = 10x + 10Since these angles are corresponding angles and lie on two parallel lines, their value will be equal.
Which means :
[tex] = \tt12x - 4 = 10x + 10[/tex]
[tex] = \tt12x - 4 - 10x = 10[/tex]
[tex] = \tt12x - 10x = 10 + 4[/tex]
[tex] = \tt2x = 14[/tex]
[tex] =\tt x = \frac{14}{2} [/tex]
[tex] =\color{plum}\tt x = 7[/tex]
Thus, the value of x = 7.
Let's place 7 in the place of x and see if their value matches :
12x - 4[tex] = \tt12 \times 7 - 4[/tex]
[tex] = \tt84 - 4[/tex]
[tex] = \tt80[/tex]
Thus, ∠12x - 4 = 80°
10x + 10[tex] =\tt 7 \times 10 + 7[/tex]
[tex] = \tt70 + 10[/tex]
[tex] = \tt80[/tex]
Thus, ∠10x + 10 = 80°
Since the value of these two angles are equal, we can conclude that we have found out the correct measure of each angle.
Therefore, the correct option is - (A) 12x - 4 = 10x + 10; x = 7
