super easy question. what's the pattern??? I thought it might be adding a prime number each time.
Answers
Hey there! :)
Answer:
f(n) = n²
Step-by-step explanation:
Let n be the term number of this pattern and f(n) the number of shapes: Examine the pattern shown:
When n = 1, f(n) = 1.
When n = 2, f(n) = 4.
When n = 3, f(n) = 9.
The pattern of this sequence is:
f(n) = n².
This means that the # of shapes shown is the square of the term number.

Answer:
C. Adding 18 to both sides isolates the variable term
Step-by-step explanation:
We can get rid of A and C because we can clearly see that we are adding, not subtracting.
The reason why C is correct is because we are isolating 6x, the term, and not x, the variable.
Your end goal is to isolate “x” which is a variable. However, the variable is multiplied by 6 and is “6x” making it a variable term. You must first isolate the variable term before you can isolate the variable itself. So step 1 is to add 18 to both sides (cancelling it out on the left side of the equals sign), thus isolating the variable term.
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
Answers
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.
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
Answers
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.

Step-by-step explanation:
We have to draw a combined form of the two inequalities on a number line.
h ≥ -5 and h < 2
For h ≥ -5,
We will draw an arrow starting from (-5) with a dark circle heading towards positive integers on a number line.
For h < 2,
We will draw an arrow starting from integer 2 with a hollow circle heading towards the negative integers on the number line.
By combining these inequalities we get a common segment between the integers -5 and 2 with a dark circle at (-5) and a hollow circle at (2).
Option (2) will be the answer.

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?
Answers
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.

A circle with radius of 1 cm sits inside a 11 cm x 12 cm rectangle.
What is the area of the shaded region?
Round your final answer to the nearest hundredth.
Answers
Answer:
128.86 square centimetres
Step-by-step explanation:
I will assume that the shaded region is the area in between the circle and the rectangle.
All we have to do is find the area of the circle and subtract it from the area of the rectangle.
Area of a circle is given as:
[tex]A = \pi r^2[/tex]
where r = radius
The radius of the circle is 1 cm, so, the area of the circle is therefore:
[tex]A = \pi * 1^2[/tex] = 3.14 square centimetres
The area of a rectangle is given as:
A = L * B
The dimensions of the rectangle are 11 cm by 12 cm. The area of the rectangle is:
A = 11 * 12 = 132 square centimetres
The area of the shaded part is therefore:
A = 132 - 3.14 = 128.86 square centimetres

It takes 1 hour (t) to fill the water tank of volume (V) 750 m3. Identify the dependent and the independent variables.
Answers
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.
Krzysztof solved the quadratic equation $11x^2-44x-99=0$ by completing the square. In the process, he came up with the equivalent equation (x+r)^2 = s, where $r$ and $s$ are constants. What is $r+s$?
Answers
Answer:
r = -2
s = 13
Step-by-step explanation:
Given quadratic equation is,
11x² - 44x - 99 = 0
Divide this equation by 11,
x² - 4x - 9 = 0
x² - 2(2)x - 9 = 0
x² -2(2)x + 2² - 2² - 9 = 0
[x² - 2(2)x + 2²] - 4- 9 = 0
(x - 2)² - 13 = 0
(x - 2)² = 13
[x + (-2)]² = 13
By comparing this equation with (x + r)² = s
Values of the constants r and s will be,
r = (-2) and s = 13

takes Brielle 10 minutes to run 1.25 miles and Joshua 18 minutes to run 1.5 miles. If
they run at the same speed for the entire shift, who will run the marathon faster?
How many minutes will it take each of them to run the race? help plss
Answers
Answer:Brielle will run the half marathon race faster.Brielle will take 1 hour 44 minutes and 48 seconds, Joshua will take 2 hours 37 minutes and 12 seconds
Step-by-step explanation:
10 / 1.25 = 8
8 minutes a mile
18 / 1.5 = 12
12 minutes a mile
Brielle will run the half marathon race faster.
8 x 13.1 =104.8
12 x 13.1=157.2
104.8 - 60=
44.8
60 seconds x .8= 48
Brielle will take 1 hour 44 minutes and 48 seconds
157.2 - 120 = 37.2
60 seconds x .2 = 12
Joshua will take 2 hours 37 minutes and 12 seconds
