The area of the given cloth is 1/6 yards².
What is an area?The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.So, the area of the cloth:
The length of the cloth is 5/9 yards.The breadth of the cloth is 3/10 yards.So, we know that it is a rectangular cloth.
Area of rectangle: l × bCalculate the area as follows:
l × b5/9 × 3/1015/901/6 yards²

A student is riding a bicycle and sees a traffic light that is 50 feet away.The vertical distance between the traffic light and the student is 14 feet.The student also notices a helicopter at an angle of elevation of 82°.The helicopter is directly above the traffic light.To the nearest tenth of a foot ,what is the vertical distance between the student and the helicopter?
Answer:
50-14= your answer .
82-your answer
Step-by-step explanation:
The vertical distance between the student and the helicopter is 341.5 feet.
What are trigonometric angles?Trigonometric angles are the angles in a right-angled triangle using which different trigonometric functions can be represented. Some standard angles used in trigonometry are 0º, 30º, 45º, 60º, 90º.
Given that, a student is riding a bicycle and sees a traffic light that is 50 feet away.
Here, sinx°= 14/50
sinx°=0.28
x°=16.26°
Now tan16.26°=14/p
0.2916=14/p
p=14/0.2916
p=48
tan82°=v/48
7.1153=v/48
v=7.1153×48
v=341.5 feet
Therefore, the vertical distance between the student and the helicopter is 341.5 feet.

You are at the bottom of a mountain where the temperature is 74°F. The top of the mountain is 5500 feet above you. What is the temperature at the top of the mountain?
For every 1,000 feet you go up in elevation, the temperature decreases by about 3.3°F
Given:
Temperature at the bottom of the mountain is 74°F
The top of the mountain is 5500 feet above you
Change (reduction) in temperature is 3.3 X 5500 / 1000
= 18.15°F
Temperature at the top of the mountain is 74°F – 18.15°F
= 55.85°F

The table that shows the relationship between the weights of pints of blueberries is a linear regression function
The equation of the line is y = 0.75xTen pints of blueberries weigh about 7.5 pounds.Ten pints of blueberries will cost about $16.875The graphThe table entry is given as:
x 0 1 2 3 4 5

See attachment for the graph
The points on the lineA line that could best approximate the points could go through the origin (0,0) and (5,3.75)
The line equationWe have the points to be (0,0) and (5,3.75)
Since the line passes through the origin, the equation of the line would be:
[tex]y = \frac{y_2}{x_2}x[/tex]
So, we have:
[tex]y = \frac{3.75}{5}x[/tex]
[tex]y = 0.75x[/tex]
Hence, the equation of the line is y = 0.75x
The weight of 10 pints of blueberriesThis means that x = 10.
So, we have:
y = 0.75 * 10
y = 7.5
Hence, ten pints of blueberries weigh about 7.5 pounds.
The cost of 10 pints of blueberriesThe unit rate is $2.25 per pound
Ten pints of blueberries weigh about 7.5 pounds.
So, the cost of 10 pints is:
Cost = 7.5 * 2.25
Cost = 16.875
Ten pints of blueberries will cost about $16.875

Martin is laying out a design for the tiles on a section of his bathroom floor. He will use 1 black tile for every 4 white tiles to have total of 20 tiles in the design. How many of each type of tile will Martin use?
Answer:
[tex]Black = 4[/tex]
[tex]White = 16[/tex]
Step-by-step explanation:
Given
[tex]Black : White = 1 : 4[/tex]
[tex]Total = 20[/tex]
Required
Determine the number of each type used
Convert each ratio to fraction.
For Black, we have:
[tex]Black = \frac{1}{1 + 4} = \frac{1}{5}[/tex]
For White, we have:
[tex]White = \frac{4}{1 + 4} = \frac{4}{5}[/tex]
The number of tiles for each is then calculated as:
[tex]Black = \frac{1}{5} * Total[/tex]
[tex]Black = \frac{1}{5} * 20[/tex]
[tex]Black = \frac{20}{5}[/tex]
[tex]Black = 4[/tex]
[tex]White = \frac{4}{5} * Total[/tex]
[tex]White = \frac{4}{5} * 20[/tex]
[tex]White = \frac{4 * 20}{5}[/tex]
[tex]White = \frac{80}{5}[/tex]
[tex]White = 16[/tex]

Step-by-step explanation:
Using ƒ(x) = 2x + 7 and g(x) = x − 3, find ƒ(g(-2)).
Answer:
We conclude that:
f(g(-2)) = -3
Step-by-step explanation:
Given
f(x) = 2x + 7g(x) = x-3To determine
f(g(-2)) = ?In order to determine f(g(-2)), first we need to determine g(-2)
so substituting x = -2 in g(x) = x-3
g(-2) = -2 - 3
= -5
Thus,
f(g(-2)) = f(-5)
now substitute x = -5 in the function f(x) = 2x+7
f(x) = 2x+7
f(-5) = 2(-5) + 7
f(-5) = -10 + 7
f(-5) = -3
so
f(g(-2)) = f(-5) = -3
Therefore, we conclude that:
f(g(-2)) = -3

A business has two delivery trucks. The weight of the first truck is 7.5 tons. The weight of the second truck is 8.75 tons. What is the difference in the weight of the trucks in pounds?
Answer:
2500 pounds
Step-by-step explanation:
There are 2000 pounds in one ton.
Find the weight of the first truck in pounds:
7.5(2000)
= 15000
Find the weight of the second truck in pounds:
8.75(2000)
= 17500
Now, find the difference in the weight:
17500 - 15000
= 2500 pounds
So, the difference in the weight of the trucks in pounds is 2500 pounds

Plsss help I don't know how to graph I will give brainiest!
Answer: (2, 5)
Step-by-step explanation:
y = 2x + 1 y = 4x − 3
Eliminate the equal sides of each equation and combine.
2x + 1 = 4x − 3
Solve 2x + 1 = 4x − 3 for x.
Move all terms containing x to the left side of the equation.
Subtract 4x from both sides of the equation.
2x + 1 − 4x = −3
Subtract 4x from 2x.
−2x + 1 = −3
Move all terms not containing x to the right side of the equation.
Subtract 1 from both sides of the equation.
−2x = −3 − 1
Subtract 1 from −3.
−2x = −4
Divide each term by −2 and simplify.
x = 2
Evaluate y when x = 2.
Substitute 2 for x. y = 4 (2) − 3
Simplify 4 (2) − 3.
Multiply 4 by 2.
y = 8 − 3
Subtract 3 from 8.
y = 5

Which function's graph is shown below?
Answer:
B: y=sinx
Step-by-step explanation:
the parent sine function is a repeating function that goes from 0 to 1, with sin(0)=0 sin(pi/2)=1 sin(pi)=0 sin(3pi/2)=-1 and sin(2pi)=0, π≈3.1415926 and we see on this graph that the graph matches at all these major points.
the cosine parent function is essentially the same thing but shifted to the left by π/2. It is essential to familiarize yourself with the unit circle and the key angles and their respective sin and cosine values.
