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

The basketball game sold
adult tickets and
student tickets.
Answers
Answer:
The basketball game sold 439 adult tickets and 858 student tickets.
Step-by-step explanation:
A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is, in the systems of equations, one must look for the values of the unknowns, with which when replacing, they must give the solution proposed in both equations.
Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,047 was collected on the sale of 1,291 tickets.
With "x" the number of adult tickets sold and "y" the number of student tickets sold, you have the following system of equations:
[tex]\left \{ {{x+y=1291} \atop {5*x+1*y=3047}} \right.[/tex]
Through the substitution method, you must solve for one of the unknowns in one of the equations and substitute its value in the following one: in this case you solve for the variable y from the first equation:
y=1291 -x
and you replace in the second equation:
5*x + 1291 - x= 3047
Solving, you get:
5*x-x= 3047 - 1291
4*x= 1756
x= 1756÷4
x=439
Replacing this value in the expresion y=1291 -x you get:
y=1291 -439
y= 858

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

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

Answer:
Well, for triangle rectangles, we have the relations:
Cos(A) = (adjacent cathetus)/(hypotenuse)
Sin(A) = (opposite cathetus)/(hypotenuse)
Tan(A) = (opposite cathetus)/(adjacent cathetus)
Where the adjacent cathetus is the cathetus that is adjacent to the angle, the opposite cathetus is the one that is opposite to the angle, and the hypotenuse is the side that is opposite to the 90° angle.
Here we want to solve 3 to 9.
3) We want to find values sin(D) and sin(E) in that triangle.
Remember the above relationship for the sin function, here will have:
sin(D) = 12/15 = 0.8
sin(E) = 9/15 = 0.6
4)
Sin(E) = 12/37 = 0.3243
Sin(D) = 35/37 = 0.9459
5)
Sin(E) = 45/53 = 0.8491
Sin(D) = 28/53 = 0.5283
6)
Remember that: Sin(A) = (opposite cathetus)/(hypotenuse)
In the image, 5 is the adjacent cathetus to the angle A, and the opposite cathetus to angle A is the one in front of it, 12, then the equation should be:
Sin(A) = 12/13
Now we should use the cosine relationship:
Cos(A) = (adjacent cathetus)/(hypotenuse)
7)
Cos(X) = 27/45 = 0.6
Cos(Y) = 36/45 = 0.8
8)
Cos(X) = 15/17 = 0.824
Cos(Y) = 8/17 = 0.4706
9)
Cos(X) = 13/26 = 0.5
Cos(Y) = (13*√3)/26 = 0.866
