Answer:
56 ft
Step-by-step explanation:
The geometry can be modeled by a right triangle with an unknown hypotenuse, and a side opposite the 30° angle that is 28 ft.
sin(30°) = (28 ft)/hypotenuse
hypotenuse = (28 ft)/sin(30°) = 56 ft
The length of the escalator is 56 feet.

The volume of the barrel is 4.6 m. It is half water. How many liters of water are there?
Answer:
2300 liters of water.
Step-by-step explanation:
The volume of the barrel is 4.6 m^3, and we know that this is half--filled with water.
Then the total volume of water inside the barrel is:
(4.6 m^3)/2 = 2.3 m^3
So we have 2.3 m^3 of water, and we want to write this in liters.
We know that 1 liter = 0.001 m^3
then:
1 = (1 L)/(0.001 m^3)
Now we can rewrite:
2.3 m^3 = (2.3 m^3)*1 = (2.3 m^3)* (1 L)/(0.001 m^3) = (2.3 m^3/0.001 m^3)* 1L
2.3 m^3 = 2300 L
So we have 2300 liters of water in the barrel.

Find the circumference of both circles to the nearest hundredth. The circumference of the green circle is about meters
*The diagram is attached below.
Answer:
Circumference of Green Circle = 138.16 m
Circumference of Blue Circle = 69.08 m
Step-by-step explanation:
The radius of the green circle = 22 m
Radius of the blue circle = ½ the radius of the green circle = ½*22 = 11 m
Circumference is given as C = 2πr
Circumference of the Green circle = 2*3.14*22 = 138.16 m
Circumference of the Blue Circle = 2*3.14*11 = 69.08 m

Which square root is between 4 and 5?
O 10
O 14
O24
O 32
Answer:
√24 because it's lies on between of√16 and√25.
The only square root that falls between 4 and 5 is √24.
What is Number system?A number system is defined as a system of writing to express numbers.
We can estimate the value of each square root and see which one falls between 4 and 5:
The value of √10 is less than 4 because √10 is, 3.16
√14 is less than 4.5 because √14 value is 3.76
√24 is greater than 4.5 because √24 value is 4.89
√32 is greater than 5 because 5 x 5 = 25, and √32 is slightly smaller than 5.
Therefore, the only square root that falls between 4 and 5 is √24.

What is 70% of 58?
Please help me I will really appreciate it ♡
Answer:
40.6
Step-by-step explanation:
0.7(58)
Answer:
40.6
Step-by-step explanation:
When finding a percentage of something you have to turn the percentage into a decimal. You divide by 100 so 70/100 is equal to 0.70. Simply mutiply this by 58 so .7*58=40.6
70% of 58 = 40.6

How wide is an 80" widescreen TV (MEASURED DIAGONALLY) if it has a height of 48”?
Answer:
64"
Step-by-step explanation:
Pythagoras theorem
√(80²-48²)
√4096
=64
Answer:
Width = 64"
Step-by-step explanation:
It forms a right angled triangle. We can use Pythagorean theorem to find the base of the triangle
Base² + altitude² = Hypotenuse²
base² + 48² = 80²
base² + 2304 = 6400
base² = 6400 - 2304
base² = 4096
base = √4096
base = 64
Width = 64"
Find the measure of the indicated angle. Round to the nearest degree.

Answer:
62 degrees
Step-by-step explanation:
Cos ? = 25 / 54
25 / 54 = 0.4629
Cos-1 of 0.4629 is 62.4215
Round to the nearest degree
62.4215 = 62
What is the domain of the function y= (square root) x+6-7
Answer:
the third choice. x>_-6
Step-by-step explanation:
1. When you have the square root of (x+6), it shifts the graph 6 units to the left.
2. So the x values would start and include -6 and continue growing to the right.
3. So the domain (x values) of the equation is x is greater than or equal to -6
Select ALL the ratios that are equivalent to 16 : 6
32:12
8:3
3:8
4:2
Answer:
32:12
8:3
Step-by-step explanation:
If you multiply both sides of 16:6 you'll get 32:12
If you divide both side of 16:6 by 2 you'll get 8:3
The same thing needs to be done to both sides to make the ratio equivalent
Answer:
16:6
32:12
8:3
multiply/divide both sides by the same number to get the answers :)
16/2:6/2 = 8:3 and so on

Please show working out in an equation form if possible
a) We were told that relationship between the value of the car and its age is linear. This means that it can be represented with a linear equation such as
y = mx + c
y is the dependent variable and in this case, it is the value of the car, V
x is the independent variable and in this case, it is the age of the car, a
The above equation is the slope intercept form equation where
m represents slope
c represents y intercept
The formula for determining slope is expressed as:
m = (y2 - y1)/(x2 - x1)
We were told that a 5 year old car is worth 14000. This means that
When x1 = 5, y1 = 14000
Also, the same car is worth 11400 after 2 years. This means that the car is worth 11400 after 7 years. Thus,
when x2 = 7, y2 = 11400
Thus,
slope, m = (11400 - 14000)/(7 - 5) = - 2600/2
m = - 1300
We would find the y intercept, c by substituting m = - 1300, x = 5 and y = 14000 into the slope intercept equation. Thus,
14000 = - 1300 * 5 + c
14000 = - 6500 + c
c = 14000 + 6500
c = 20500
Thus, by substituting m = - 1300 and c = 20500 into the slope intercept equation, the linear equation representng this scenario is
y = - 1300x + 20500
By replacing with the given variables,
V = - 1300a + 20500
b) When the car was new, it means that a = 0. By substituting a = 0 into the equation, we have
V = - 1300 * 0 + 20500
V = 20500
The value of the car was $20500 when it was new
