Answer:
Step-by-step explanation:
if you have one side =2/7
area = (2/7)^2=4/49 m^2
To find the area of a square, we need to know the length of one of its sides. In this case, the given length of a side is 2/7m. So, the area of the square is 4m² / 49.
To find the area, we use the formula A = s², where A represents the area and s represents the length of a side. Let's substitute the given value into the formula:
A = (2/7m)²
To square 2/7m, we multiply it by itself:
A = (2/7m) × (2/7m)
To multiply fractions, we multiply the numerators together and the denominators together:
A = (2 × 2) / (7 × 7) × m × m
Simplifying the numerator and denominator:
A = 4 / 49 × m × m
Finally, we can write the area as a fraction:
A = 4m² / 49
So, the area of the square is 4m² / 49.

Answer:
[tex]x = 3[/tex][tex]y=3\sqrt{3}[/tex]Step-by-step explanation:
From the given right-angle triangle
The angle = ∠60°
The adjacent to the angle ∠60° is x.The opposite to the angle ∠60° is y.The hypotenuse = 6
Using the trigonometric ratio
cos 60° = adjacent / hypotenuse
substituting adjacent = x and hypotenuse = 6
cos 60° = x / 6
6 × cos 60° = x
x = 3
Thus, the value of x is:
x = 3And using the trigonometric ratio
sin 60° = opposite / hypotenuse
substituting opposite = y and hypotenuse = 6
[tex]sin\:60^{\circ }\:=\:\frac{y}{6}\:[/tex]
[tex]y=6\:\times\:sin\:60^{\circ }[/tex]
[tex]=6\times \frac{\sqrt{3}}{2}[/tex] ∵ [tex]\sin \left(60^{\circ \:}\right)=\frac{\sqrt{3}}{2}[/tex]

The movie theater can hold a maximum of 7,000 people. This weekend, they are expecting 4,600 children and 765 adults. How many seats will be left?
Answers
Answer:
1635 seats left
Step-by-step explanation:
First, add the number of children and adults as they are both considered people.
4600 + 765 = 5365
Then we do subtraction to figure out how many seats are left
7000 - 5365 = 1635. There will be 1635 seats left

Henry is flying a kite. The kite makes an angle of 43 with the ground. If henry is standing 100 feet from a point on the ground directly below the kite, find the length of the kite string
Answers
Answer:
x = 136.73 feet
Step-by-step explanation:
Given that,
Henry is flying a kite. The kite makes an angle of 43 with the ground. If henry is standing 100 feet from a point on the ground directly below the kite.
We need to find the length of the kite string. It can be calculated by using trigonometry.
The length of the string will be hypotenuse, 100 feet is the base.
The relation between the hypotenuse, base and angle with the ground is given by :
[tex]\cos\theta=\dfrac{\text{base}}{\text{Hypotenuse}}\\\\\cos(43)=\dfrac{100}{x}\\\\x=\dfrac{100}{\cos(43)}\\\\x=136.73\ \text{feet}[/tex]
So, the length of the kite string is 136.73 feet.

The number in the hundreds place is one more that the number in the tens place.
Let the number in the tens place is x.
Number in the hundreds place = 1+x
These two numbers equal 11.

Where is the point -3,4 located on a coordinate plane?
Answers
Answer:
It is located 3 to the right and 4 up or in the second quadrant
Step-by-step explanation:
Answer:
See the image that has been attached.
Step-by-step explanation:
On a coordinate plane, the x value is always first in a coordinate pair. The y value is second.
This means that -3 is the x value. X values go left and right, so -3 is three left from 0,0.
The same goes for the y value. Since the y value is 4, the y value is 4 is 4 up from 0,0.

To determine the height of the volcano Mount Saint Helens, a surveyor measured the angle of elevation to the top of the volcano to be 34.8°. She then moved 1000 feet closer to the volcano and measured the angle of elevation to be 40.4° Determine the height of Mount Saint Helens to the nearest foot.
Answers
Answer:
The height is 3791 ft.
Step-by-step explanation:
You need to make a drawing. Start with a vertical segment, 2 inches long, on the left side of the page. Label the top point A and the bottom point B. At the bottom endpoint, draw a longer horizontal segment, 4 inches long, to the right. Label the bottom right endpoint C. Connect A and C with a segment. Angle C is the original angle of elevation. On the bottom horizontal side, approximately 1 inch to the left of C, draw point D. Connect D and A with a segment. DA = 1000 ft. m<C = 34.8°. m<ABD = 40.4°. We are looking for AB, the height of the volcano.
We can work on triangle ADC.
m<C = 34.8°
Angles ADB and ADC are a linear pair, so m<ADC = 180° - 40.4° = 139.6°
m<DAC + m<ADC + m<C = 180°
m<DAC + 139.6° + 34.8° = 180°
m<DAC = 5.6°
Using the law of sines, we can find AC.
[tex] \dfrac{\sin A}{a} = \dfrac{\sin B}{b} [/tex]
[tex]\dfrac{\sin 5.6^\circ}{1000} = \dfrac{\sin 139.6^\circ}{AC}[/tex]
[tex]AC = \dfrac{1000\sin 139.6^\circ}{\sin 5.6^\circ}[/tex]
[tex] AC = 6642~ft [/tex]
Now we use triangle ABC. AC = hypotenuse. AB = opposite leg. <C is known angle.
[tex] \sin C = \dfrac{opp}{hyp} [/tex]
[tex]\sin 34.8^\circ = \dfrac{AB}{6642~ft}[/tex]
[tex]AB = 6642~ft \times \sin 34.8^\circ[/tex]
[tex] AB = 3791~ft [/tex]

Which model represents 2.36 ÷ 4? A. Three groups of three tenths and four hundredths B. Three groups of five tenths and nine hundredths C. Four groups of three tenths and six hundredths D. Five groups of five tenths and nine hundredths
Answers
Answer:
Five groups of five tenths and nine hundredths
Step-by-step explanation:
Mathematically;
2.36 divided by 4 = 0.59
So we want to select from the options, the best representation of this
That will be
0.5 + 0.09
so our answer is 5 groups of five tents and nine hundredths
The model which represents 2.36 ÷ 4 is; Choice D: Five groups of five tenths and nine hundredths
We must perform the division 2.36 ÷ 4 first so that we have;
2.36 ÷ 4 = 0.59The result, 0.59 can then be written in words as; Five tenths and 9 Hundredths.
Ultimately, the model. which represents the expression 2.36 ÷ 4 is; Choice D: Five groups of five tenths and nine hundredths.

The table shows the linear relationship between the balance of a student's savings account and the number of weeks he has been saving.
Based on the table, what was the rate of change of the balance of the student's savings account in dollars and cents per week?
Answers
Answer:
the rate of change is 7.
Step-by-step explanation:
The rate of change of the balance of the student's savings account in dollars and cents per week is 7.
How to measure the rate of change of something as some other value changes?Suppose that we have to measure the rate of change of y as x changes, then we have:
[tex]Rate = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
Remember that, we have to divide by the change in an independent variable so that we get an idea of how much the dependent quantity changes as we change the independent quantity by 1 unit.
We have given the table of saving accounts, then the rate will be;
[tex]Rate = \dfrac{39 - 32}{1 - 0}\\Rate = \dfrac{7}{1 }[/tex]
Therefore, the rate of change of the balance of the student's savings accounts in dollars and cents per week is 7.

Question Solve for x 3x = x + 8
Answers
Answer:
x=4
Step-by-step explanation:
here's our equation: 3x=x+8
Our goal: to isolate x onto one side with nothing else on that side.
x is on both sides; we can subtract x from both sides to make the variables and numbers be on different sides
2x=8
Now we can divide by 2
x=4
Hope this helps! :)
3x = x + 8
Step 1: Subtract x from both sides.
3x−x=x+8−x
2x=8
Step 2: Divide both sides by 2.

Answers
Answer:

Step-by-step explanation:
This situation can be represented as y=x^3 where y is the volume of the cube x is the length of its side. We find that the slope for this curve(change in y/change in x) is not constant for all points on the curve. Thus it is a non linear function.
