Answer:
Same side interior angles are supplementary, meaning they add up to 180°. We can call the two angles x° and (x + 20)° and we can write the equation:
x + x + 20 = 180
2x + 20 = 180
2x = 160
x = 80 which means the angles are 80° and 80 + 20 = 100°.
It takes 1 hour (t) to fill the water tank of volume (V) 750 m3. Identify the dependent and the independent variables.
Answer:
The time t is the independent variable while the volume V is the dependent variable
Step-by-step explanation:
A variable is a parameter that changes.
We have two types namely dependent and independent variables.
A dependent variable is a variable which its value needs to be determined based on the value of another variable while and independent variable is a variable which its value independent of other parameters.
In our question, It takes 1 hour (t) to fill the water tank of volume (V) 750 m3.
The volume of the tank V changes as time changes. So the volume of the tank V is dependent on time, t.
So V is proportional to t
Since the volume of the tank is the variable that needs to be determined based on another variable-which is time,t- it is the dependent variable, while the time,t is the independent variable since its value is not determined based on other parameters.

An open cone has a slant height of 5m and a curved surface area of 251, Find the radius of the circular base.What is the answer:18 16
Answer:
Radius of the cone = 16 m
Step-by-step explanation:
Slant height of the cone 'l' = 5 m
Curved surface area of the cone is represented by the formula,
Curved surface area = πrl
Here r = radius of the circular base of the cone
l = slant height of the cone
By putting the values in the formula,
251 = πrl
251 = πr(5)
r = [tex]\frac{251}{5\pi}[/tex]
r = 15.979
r ≈ 16 m
Therefore, radius of the given cone will be 16 m.

x = 2y - 3 & 3x - 7y = -14
Answer:
(7, 5)
Step-by-step explanation:
You can solve by substitution
3(2y - 3) - 7y = -14
6y - 9 - 7y = -14
-y - 9 = -14
-y = -5
y = 5
x = 2(5) - 3
x = 7
Answer:
(7, 5).
Step-by-step explanation:
x = 2y - 3
2y = x + 3
y = x/2 + 3/2
3x - 7y = -14
-7y = -3x - 14
y = 3/7x + 2
3/7x + 2 = 1/2x + 3/2
6/14x - 7/14x = 1.5 - 2
-1/14x = -1/2
1/14x = 1/2
x = 7
7 = 2y - 3
2y = 10
y = 5
3 * 7 - 7 * 5 = 21 - 35 = -14
Since this works, your answer will be (7, 5).

A subtending arc on a circle with a radius of 4.5 centimeters has an arc length of 8π. The measure of the angle subtended by the arc is °.Which angle measure less than or equal to 360° is equivalent to an angle of ?
Answer:
320°
Step-by-step explanation:
Part 1
The arc length is given by ...
s = rθ . . . . . r is the radius, θ is the central angle in radians
We want to find θ, so we can fill in the given values and divide by the coefficient of θ.
8π = 4.5θ
θ = 8π/4.5 = 16π/9 . . . radians
Since π radians = 180°, the degree measure of the angle is ...
θ = (16/9)180° = 320°
The measure of the angle subtended by the arc is 320°.

Mary went up the Old Tower taking 3 steps per second. Then she carefully came down from the tower taking 2 steps per second. It took Mary 25 seconds longer to come down than to go up. How many steps does the Old Tower have?
Answer:
old town has 150 steps
Step-by-step explanation:
Let the number of steps in the old tower be m
Mathematically, time = distance/speed
In this case, the distance is the number of steps while the speed is the rate of climbing or descending
For climbing, time spent = m/3
For descending time spent = m/2
Since it took her 25 longer when descending;
This means that;
m/2 - m/3 = 25
(3m-2m)/6 = 25
m/6 = 25
m = 6 * 25
m = 150 steps
Gwen is travelling to another country. She flies for 3 hours at an average speed of 625 km/h on one plane. She then flies for 4 hours 15 minutes at an average speed of 880 km/h on a second plane. What is the total distance, in km, she travelled by plane?
Answer:
5,615 km.
Step-by-step explanation:
The first flight, she traveled for 3 hours at a speed of 625 km/h.
[tex]\frac{625}{1} =\frac{x}{3}[/tex]
x = 625 * 3
x = 1,875.
The first flight, she traveled 1,875 km.
The second flight, she traveled for 4.25 hours at a speed of 880 km/h.
[tex]\frac{880}{1} =\frac{x}{4.25}[/tex]
x = 880 * 4.25
x = 3,740.
The second flight, she traveled 3,740 km.
So, in total, she traveled 1875 + 3740 = 5,615 kilometres.

X= 3y-5
2x + 12y = -4
This is a system of equations can somebody solve it you can use any method
Answer:
x = -4, y = 1/3
Step-by-step explanation:
=> x = 3y-5 (Equation 1)
=> 2x+12y = -4 (Equation 2)
Putting (1) in (2)
=> 2(3y-5)+12y = -4
=> 6y-10+12y = -4
=> 18y = -4+10
=> 18y = 6
Dividing both sides by 18
=> y = 6/18
=> y = 1/3
Putting y = 1/3 in Equation 1
=> x = 3(1/3)-5
=> x = 1-5
=> x = -4
The volume of a rectangular prism is 240 cubic centimeters. A rectangular pyramid has the same length, width, and height as the prism. What is the volume of the pyramid?
Answer:
The volume of the pyramid is 80 cubic centimeters.
Step-by-step explanation:
As the formula for the volume of a pyramid is 1/3bh, so if all the dimensions are the same for both figures, just divide the volume of the prism by three to find the volume of the pyramid. If you do this 240÷3=80 or the volume of the pyramid.
Answer:
80 cubic centimetres
Step-by-step explanation:
The volume of a rectangular prism is given by V = lwh, where l is the length, w is the width, and h is the height.
Here, we know that the prism's volume is 240, so lwh = 240.
The volume of a rectangular pyramid is denoted by V = (1/3) * lwh, where l is the length of the rectangular base, w is the width of the rectangular base, and h is the height.
We know that the length, width, and height of the pyramid are the same as those of the prism, so we want to simply find V = (1/3) * lwh. From the prism, we see that lwh = 240, so plug that in:
V = (1/3) * lwh
V = (1/3) * 240 = 80
The answer is thus 80 cubic centimetres.

In the diagram below, AB is parallel to CD. What is the value of x?
Answer:
150 degrees
Step-by-step explanation:
You can figure this out by looking at the degrees below d, and you see it is thirty, and that it is equal to the degree above the x, so then you subtract 30 from 180 to get 150. Hopefully that makes sence, I forgot what some of the terms are called.

To speed the process of surveying, surveyors use brass metal plates to record important information. The benchmarks, as they are called, are used to save time so surveyors do not have measure the datum plane each time. Benchmarks refer to what standard of measurement? Feet above sea level
Answer:
Feet Above Sea Level
Step-by-step explanation:
A benchmark is a term in Surveying and Geo informatics, that describes a point of reference established at a known elevation which serves as basis in which other elevation or topographical point can be measured.
Therefore, when determining the benchmark, it's height is calculated relative to the vertical datum of the area, typically mean sea level, which is then recorded in FEET ABOVE SEA LEVEL.
Hence, Benchmarks measurements refer to FEET ABOVE SEA LEVEL.
The table below shows some inputs and outputs of the invertible function f with domain all real numbers. NEED HELP NOW!!!!!
Answer:
( 1 ) [tex]f^{-1}(f(576)) = 576[/tex],
( 2 ) [tex]f^{-1}(-7)+f(-7) = 13[/tex]
Step-by-step explanation:
Taking the function and it's inverse, it should be the following property -
[tex]f^{-1}(f(x))= x[/tex] - this therefore makes the functionality " [tex]f^{-1}(f(576))= x[/tex] " equivalent to 576 itself.
For this second part here let's consider the portion " [tex]f(-7)[/tex] " firstly. As you can see from the table, - 7 should represent the x - value, hence [tex]f(-7) = 7[/tex]. Now for this second bit here, we have to take the inverse - making the what should have been the x - value, now the f( x ) value. Therefore, [tex]f^{-1}(-7) = 6[/tex].
This would make [tex]f^{-1}(-7)+f(-7)[/tex] = [tex]7+6[/tex] = 13.
