PLEASE HELP ME A soccer field is bordered on three sides by a parking lot of width x. The total length of the field and parking lot is 300 m, and the total width is 200 m.
The area of the field is 30.000 m². How wide is the parking lot?
Answer:
Step-by-step explanation:
Assuming the parking lot is along both widths of the field and only once along the length:
the length is (300 - 2x)
the width is (200 -x)
the area is (300-2x)(200-x) = 30000
60000 -300x - 400x +2x^2 = 30000
2x^2 -700x + 30000 = 0
x^2 - 350x + 15000 = 0
(x - 300 )(x - 50 ) = 0
x = 300 or x=50
x=300 results in negative measures.
the parking lot is x=50 wide
the length of the field is 200, the width of the field is 150
find the value of x

A café has a monthly fixed cost of $4700, and a typical customer order costs the café $2. Therefore, the cost to serve x customers in a month is given by x = 4,700 + 2x. The typical order costs $10. So revenue is y = 10x. Find the number of customers that would need to come in the café for the company to break even. (Intersection point)
Answer:
The number of customers that would need to come in the café for the company to break even is 470.
Step-by-step explanation:
Given
Revenue = y = 10x ……………….…. (1)
Cost = x = 4,700 + 2x ……………… (2)
Since the company will break even when Revenue is equal to Cost, we therefore equate equations (1) and (2) and then solve for x as follows:
10x = 4,700 + 2x
10x - 2x = 4,700
x = 4,700 / 10
x = 470
Therefore, the number of customers that would need to come in the café for the company to break even is 470.

Answer:
x = 51°
Step-by-step explanation:
The straight line segment has a total angle of 180°. Therefore, to find the angle inside the triangle that is next to 94°, subtract 94 from 180:
180° - 94° = 86°
That angle is almost a right angle but not quite. Now, to find x, add up the two angles inside the triangle and subtract it from 180°:
43° + 86° = 129°
180° - 129° = 51°

there are 45 students In a class. if 60% of them are girls. find the numbers of girls and boys
Step-by-step explanation:
No. of students in class = 45 .
Percentage of girls = 60% .
No . of girls = 45 × 60/100 = 45 × 3/5 = 18 .
No. of boys = 45 - 18 = 27
Answer:
27 girls
18 boys
Step-by-step explanation:
Convert 60% to a decimal.
60% · .01 = 0.6Multiply 45 students by 0.6 to find the number of girls in the class.
45 * 0.6 = 27 girlsSubtract this amount from the total number of students in the class.
45 - 27 = 18 boysThere are 27 girls and 18 boys in the class.

Kyle is at the end of a pier 30 feet above the ocean. His eye level is 3 feet above the pier. He is using binoculars to watch a whale surface. If the angle of depression of the whale is 20(degrees), how far is the whale from kyles biboculars? round to the nearest tenth foot
Answer:
96.5 feet. looked it up.
Step-by-step explanation:
Have a great day:)
Answer:
Given: the angle of depression= 20°
Height of Kyle from the ocean = 30 feet
To find: how far is the whale from kyles biboculars?
Step-by-step explanation:
Let the distance between them be y
sin20° = [tex]\frac{33 }{y}[/tex]
=> 0.342 = [tex]\frac{33}{y}[/tex] [ sin20° = 0.342]
=> y = 33/ 0.342
=> y = 96.5 ft
So, the distance between them is 96.5 ft
what is angle of depression?
The angle of depression is the angle formed by the horizontal line and the horizontal line's observation of the item. When we know the angles and the distance of an object from the ground, it is primarily utilized to find the distance between the two objects. If the line of sight is directed downward from the horizontal line, then an angle is created with the horizontal line.
The angle produced between the horizontal line and the observer's line of sight is known as the angle of depression if the object being observed is below the observer's level. The angle of depression is shown in the image below as.

area circle = πr² or π(d/2)² but how to find the diameter?
The only angles I can see to calculate is in the small right triangle
The smaller angle on the right is ...
sin Ф = opp/hyp = 6/10 Ф = 36.87°
This angle is the same as the small angle on the LARGE right triangle
So now I want to calculate the side (diameter) opposite the smaller angle
sin Ф = opp/hyp = diameter/300 = sin 36.87°
diameter = 300 sin 36.87°
= 300 (6/10)
= 180 ft
area circle = πr² or π(d/2)²
area circle = π(180/2)²
area circle = 25446 ft² which is close to answer A 25434 ft²
There is actual no need to find the sin Ф wasted step
just use 6/10 small triangle is similar to diameter/300 the large triangle
opp / hyp small 6/10 = diameter/300 diameter = 180
area circle = π(180/2)² = 25446

Desmond really like Legos. Last Saturday Desmond counted his Legos and realized that
he has 65 altogether! Desmond has 7 less green Legos than red Legos, and the amount of
blue Legos he has is two more than three times his red Legos. How many of each color
Lego does Desmond have?
Answer Quick.
Only reply if you have the answer please
Answer: 14 red, 7 green, 44 blue
Step-by-step explanation:
First, use the letter r as a variable to represent the number of red Legos. The number of green Legos (g) is 7 less than the number of red Legos, or g = r-7. The number of blue Legos (b) is 2 more than 3 times the number of red Legos, or b = 3r+2. The total number of Legos is the number of red + green + blue Legos, which can be represented as 65 = r+g+b.
Substitute the equations for g and b in. This should give you a final equation of 65 = r+(r-7)+(3r+2). To solve for the number of red Legos, first add up all of the terms to get 65 = 5r-5. Now add 5 to each side (70 = 5r). Finally, divide each side by 5 (r = 14).
To find the number of green Legos, substitute the number of red Legos (14) into the equation for the green Legos (g = r-7). This should get you the equation g = 14-7 which simplifies to g = 7.
To find the number of blue Legos, substitute the number of red Legos (14) into the equation for the blue Legos (b = 3r+2). This gives you the equation b = (3*14)+2. First, multiply 3 and 14 to get b = 42+2. Finally, add them together to get b = 44.
Mr. Strand mowed 2 5 of his lawn. His son mowed 1 3 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?
Answer:4/15 of the portion of land is left to be mowed.
Step-by-step explanation:
Portion of Lawn mowed by Mr Strand =2/5
Changing to decimal we have 0.4
Portion of Lawn mowed by his son=1/3
Changing to decimal, we have 0.333
From this , we can deduce that Mr Strand mowed most of the Lawn.
Now to find the portion of Lawn remaining to be mowed
Let total portion be =1whole
Such that portion left to be mowed
=1-(2/5+1/3)
1- 6 + 5/15
1-11/15
15/15 -11/15
4/15 of the portion of land is left to be mowed.
