Answer:
r = 24 m
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here A = 576π , then
πr² = 576π ( divide both sides by π )
r² = 576 ( take the square root of both sides )
r = [tex]\sqrt{576}[/tex] = 24

A certain television is advertised as a 54-inch TV (the diagonal length). If the width of the TV is 40 inches, how tall is the TV? Round to the nearest tenth of an inch.
Answer:
36.3
Step-by-step explanation:
I tried using the Pythagorean Theorem to measure the length (tallness) of the TV.
[tex]a^2 + b^2 = c^2[/tex]
[tex]a^2 + (40)^2 = (54)^2[/tex]
[tex]a^2 + 1600 = 2916[/tex]
[tex]a^2 = 2916-1600 = 1316[/tex]
[tex]a = \sqrt{1316}[/tex]
[tex]a = 36.27671429[/tex]
When this is rounded up to the nearest tenth, it would go up to 36.3.
So, the length (tallness) of the TV would be 36.3 inches.

Answer:
13.7
Step-by-step explanation:
It forms a triangle.
They are trying to find the height, cause they say the east-bound car went east so that makes the bottom of the triangle, the width. They also give is the distance in between both cars so that's the hypotenuse so let's set up the equation...
15² - 6² = 189
now we square root it
√189 = 13.7

The price of 2 ratios are in x:y when the prices both increase by £20, the ratio becomes 5:2 when the prices both reduce by £5 the ratio becomes 5:1 express the x:y ratio in the lowest form
Answer:
x:y = 4:1
Step-by-step explanation:
Since their ratios are x:y, when they both increase by £20, their ratio is 5:2.
So, x + 20/(y + 20) = 5/2 (1)
When they both decrease by £5, their ratio is 5:1.
So, x - 5/(y - 5) = 5/1 (2)
Simplifying (1) and (2), we have
x + 20/(y + 20) = 5/2 (1)
cross-multiplying, we have
2(x + 20) = 5(y + 20)
expanding the brackets, we have
2x + 40 = 5y + 100
2x - 5y = 100 - 40
2x - 5y = 60 (3)
So,
x -5/(y - 5) = 5/1 (2)
cross-multiplying, we have
(x - 5) = 5(y - 5)
expanding the brackets, we have
x - 5 = 5y - 25
x = 5y - 25 + 5
x = 5y - 20 (4)
Substituting (4 into (3), we have
2x - 5y = 60 (3)
2(5y - 20) - 5y = 60
10y - 40 - 5y = 60
10y - 5y = 60 + 40
5y = 100
y = 100/5 = 20
substituting y = 20 into (4), we have
x = 5y - 20 (4)
x = 5(20) - 20
x = 100 - 20
x = 80
So, x/y = 80/20 = 4
x/y = 4/1
x:y = 4:1
3(−4)=12x What is the value of ?
Answer:
x = -1
Step-by-step explanation:
When given the following equation:
3(-4) = 12x
Simplify the left, side to perform the given operations. Remember, when there are parentheses but no operations between the two parentheses, then the operation is mutliplciation.
-12 = 12x
Inverse operations, divide both sides by (12) to undo the operation on the left side,
-1 = x
Answer:
as there is a braket add the distributive law soo it will be -12=12x and rhen u will move the the 12 from x to the other side of the equation u dived it with -12 so u
Step-by-step explanation:
the answer -1=x
Equations on both sides
3x + 5 = 2x -17
Solve it and show the work because i need to show the work
Answer:
x = -22
Step-by-step explanation:
Subtract 5 from both sides
3x + 5 (-5) = 2x - 17 (-5)
3x = 2x - 17
Subtract 2x from both sides
3x (-2x) = 2x (-2) -22
x = -22
A rope is stretched from the top of a
7-foot tent pole to a point on the ground
12 ft from the base of the pole. How long
is the rope ?
Answer:
Step-by-step explanation:
we know two sides of a triangle, one side is 7 feet, the other is 12 feet , so use Pythagoras theorem
[tex]C^{2}[/tex] = [tex]A^{2}[/tex] + [tex]B^{2}[/tex]
[tex]C^{2}[/tex] = [tex]7^{2}[/tex] + [tex]12^{2}[/tex]
[tex]C^{2}[/tex] = 49 + 144
[tex]C^{2}[/tex] = 193
C = [tex]\sqrt{193}[/tex]
C = 13.89 feet
Answer:
The square of the hypotenuse equals the square of the sum of the other two sides.
13.89ft
Step-by-step explanation:
Definition Of Pythagoras Theorem :The Pythagorean theorem states that the total of the squares on a right triangle's legs equals the square on the hypotenuse (the side opposite the right angle)—or, in popular algebraic form, a2 + b2 = c2.
Given:Height of the Tent Pole = 7ft.
Base of the Pole of the Tent = 12ft.
Now we will use Pythagoras theorem to find how long the rope is.
Use of Pythagoras theorem
[tex]\begin{aligned}&C^{2}=A^{2}+B^{2} \\&C^{2}=7^{2}+12^{2} \\&C^{2}=49+144 \\&C^{2}=193 \\&C=\sqrt{193} \\&C=13.89 \text { feet }\end{aligned}[/tex]Hence, the length of the rope is 13.89ft.

james ran 1 mile in 8 minutes in the morning and 3.5 miles in 28 minutes in the evening
cool, what's the question?
In a right triangle, a and b are the lengths of the legs and c is the length of the hypotenuse. Of a = 7 miles and b = 3 miles, what is the perimeter? If necessary, round to the nearest tenth.
Answer:
17.6 miles.
Step-by-step explanation:
Use Pythagoreans Theorem to find c.
a^2+b^2=c^2
49 + 9 = c^2
58 =c^2
√58=c
7.6=c
Now add all of your sides together to find the perimeter.
7 + 3 + 7.6 = 17.6 miles.
The perimeter of the triangle is 17.6 units.
What is the Pythagorean theorem?The Pythagorean theorem says that the sum of the square of the perpendicular and the base will be equal to the square of the hypotenuse of the right-angle triangle.
Using the Pythagorean theorem, we can find the length of the hypotenuse c:
c² = a² + b²
c² = 7² + 3²
c² = 58
c = √58 ≈ 7.6 miles
The perimeter is the sum of the three sides:
Perimeter = a + b + c
Perimeter = 7 + 3 + 7.6
Perimeter ≈ 17.6 miles

PROMISE TO GIVE BRAINIEST BUT ONLY IF YOU GET IT RIGHT!
Answer:
5.2
Step-by-step explanation:
Formula for any right triangle is a^2 + b^2 = c^2
So plug in the values and you get:
a^2 + 3^2 = 6^2
convert the squared numbers and you get:
a^2 + 9 = 36
subtract 9 from both sides
9 = 36
-9 = -9
you get:
a^2 = 27
we can't have a squared number as our answer, so we find the square root of both.
[tex]\sqrt{a^2 = 27}[/tex]
a^2 cancels out and you get:
a = 5.2 (simplified and rounded to nearest tenth)
Answer:
3√3
Step by step explanation:
36^2- 3^2= 27

Jessica made 6 19/20 cups of punch. Her punch had two different types of juices in it. If the lunch had 4 1/5 cups of one type of juice, how many cups of the other type of juice did it have?
Answer:

Step-by-step explanation:
Jessica made 6 19/20 cups of punch. Her punch had two different types of juices in it. If the lunch had 4 1/5 cups of one type of juice, how many cups of the other type of juice did it have?
We solve this question using the Subtraction operation
Total cups = cups of first type of juice + cup of other type of juice
6 19/20 = 4 1/5 cups + x
x = 6 19/20 - 4 1/5 cups
Lowest Common Denominator = 20
x = 6 - 4 + (19/20 - 1/5)
x = 2 + (19 - 4/20)
x = 2 15/20 cups
x = 2 3/4 cups
Other type of juice had 2 3/4 cups of juice

You observe the heights of two plants for an experiment. Plant A has a height of 8 centimeters and grows 1 centimeter each week. Plant B has
a height of 4 centimeters and grows 2 centimeters each week. Let x represent the number of weeks and let y represent the height of the
plant
a. Write a system of linear equations that represents this situation
System of equations:
b. Will the plants ever have the same height?
Using linear functions, it is found that:
a)
[tex]y_A(x) = 8 + x[/tex]
[tex]y_B(x) = 4 + 2x[/tex]
b) They will have the same height after 4 weeks.
A linear function has the following format:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of y when x = 0.Item a:
Plant A has a height of 8 centimeters and grows 1 centimeter each week, hence:
[tex]y_A(x) = 8 + x[/tex]
Plant B has a height of 4 centimeters and grows 2 centimeters each week, hence:
[tex]y_B(x) = 4 + 2x[/tex]
The system is:
[tex]y_A(x) = 8 + x[/tex]
[tex]y_B(x) = 4 + 2x[/tex]
Item b:
Equaling the equations:
[tex]y_A(x) = y_B(x)[/tex]
[tex]8 + x = 4 + 2x[/tex]
[tex]x = 4[/tex]
They will have the same height after 4 weeks.
