Answer:
15.13cm
Step-by-step explanation:
From that above question:
We are told that:
Lateral surface area of a right circular cone : πr√r² + h²
We are give the following parameters:
Lateral surface area = 236.64cm²
Radius = 4.75cm
We are to find the height
Making h the subject of the formula
h = √[(A/r)² - πr²]/π
h = √[(236.64/4.75)²- π ×4.75²]/π
h = 15.12975 cm
Approximately to the nearest hundredth = 15.13cm

help needed! what is 2/3 of 2? (and if possible can you give an easy explanation?)
Answer:
2/3 of 2 is 1.33
Step-by-step explanation:
this because 2/3 times 2 is 1.33
Answer:
4/3
Step-by-step explanation:
2/3 of 2 is basically multiplying 2/3*2/1.
Therefore it's (2*2)/(3*1) which is 4/3.

vo
B
Op+r=9
Op+q + r = 180 degrees
Op+q + r = 90 degrees

Step-by-step explanation:
Angles in a Circle
Let's review some concepts about angles in a circle.
The central angle is formed between two radii and its vertex lie at the center of the circle.
The inscribed angle is formed between two chords whose vertex lies on the circumference of a circle.
The measure of a central angle x formed by the same lines that define an inscribed angle y is:
x = 2y
Following the definitions and relations above, we find that:
The measure of the central angle 98° is double the inscribed angle 35°+mThe measure of the central angle n is double the inscribed angle mThe first statement leads to:
98 = 2 (35+m)
Dividing by 2:
49 = 35 + m
m = 49 - 35 = 14
m = 14°
The second statement leads to:
n = 2m = 28°
Thus: m=14°, n=28°

Is this a cubic graph?
Is it a reflection of its parent graph?
This graph shifted _ by _ units
Answer:
we conclude that the given graph is a cubic function and is translated by shifting 2 units to the left.
Thus, the graph is shifted left by 2 units.
The graph of the parent function f(x)=x³ and f(x+2) = f(x+2)² is shown below.
Step-by-step explanation:
If we carefully analyze the given graph, it is clear that the given graph is the transformed image of form f(x+b) of parent cubic graph f(x) = x³.
In this graph, the function f(x) has been moved over 2 units to the left.
In order to shift a function 2 units to the left, we need to add '2' inside the function's input.
In other words,
f(x+2) = f(x+2)² means the function f(x) is shifted 2 units to the left.
Therefore, we conclude that the given graph is a cubic function and is translated by shifting 2 units to the left.
Thus, the graph is shifted left by 2 units.
The graph diagram of the parent function f(x)=x³ and f(x+2) = f(x+2)² is shown
below.
The red graph is representing f(x)=x³The blue graph is representing f(x+2) = f(x+2)²Please, can someone help???
Answer:
using sas both C angles are the same because of vertical angles
since what is given we find that BD and AE are straight lines meaning that BA and ED are parallel
this means that angle B is congruent to angle D and the same for A and E
using sas or asa we can determine BCA and ECD congruent

Jay thinks of a prime number. The sum of its digits is one more than a square number. Write down one number jay could be thinking of.
Answer:
Jay could be thinking of 11
Step-by-step explanation:
Prime numbers are the numbers that have two factors only, 1 and itself as
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, .................
All prime numbers can divide by 1 and itself only
∵ A number is a prime number
∵ The sum of its digits is 1 more a square number
∴ The sum of its digits = 1 + x, where x is a square number
→ We will start with the first prime number of 2-digits
∵ 11 is a prime number
∵ The sum of its digits = 1 + 1 = 2
→ Substitute it in the equation above to find x
∴ 2 = 1 + x
→ Subtract 1 from both sides
∵ 2 - 1 = 1 - 1 + x
∴ 1 = x
∵ 1 is the square of 1
∴ Jay could be thinking of 11
You can check some of the other prime numbers to find another number
24 is 29% of what number? Round to the nearest tenth,
Answer:
82.8
Step-by-step explanation:
24/.29
=82.75862
but you want it rounded so 82.8 is your answer
I hope this helps
Answer:
82.8
Step-by-step explanation:
Step 1: If 29% of a number is 24, then what is 100% of that number? Set up the equation.
24 over 29% = Y over 100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
29Y = 24 x 100
29Y = 2400
Y = 2400 over 100 = 82.76
If you round 82.76 to the nearest tenth you get 82.8.

Kaitlyn start a job that pays $8.50 per hour Caitlin's manager says that if her job reviews were favourable she can expect annual pay rate increases of $0.75 which equation represents the relationship between years on the job and pay for our
Given:
Initial pay rate = $8.50 per hour
Increase in pay rate = $0.75 per year
To find:
The equation that represents the relationship between years on the job and pay for hour.
Solution:
Let x be the number of years and y be the pay rate after x years.
According to the question,
Increase in pay rate in 1 year = $0.75
Increase in pay rate in x year = $0.75x
So, variable pay rate = $0.75x
Initial pay rate = $8.50
So, the total pay rate is
Total pay rate = Initial pay rate + Variable pay rate
[tex]y=8.50+0.75x[/tex]
Therefore, the required equation is [tex]y=8.50+0.75x[/tex].
Solve the equation, showing each step of the solution.
1/2 (x – 10) = -4
Answer:
x=2
Step-by-step explanation:
first distribute the 1/2
1/2x - 5=-4
then add 5 to both sides
1/2x=1
multiple by 2 on both sides
x=2

Answer:
(1). E ; (2). C ; (3). H ; (4) A ;
Step-by-step explanation:
(1). m = [tex]\frac{1}{2}[/tex]
(2). m = 2
(3). m = - [tex]\frac{1}{2}[/tex]
(4). m = - 2
Answer:
ECHA
Step-by-step explanation:
1.) E
m = 1/2
2.) C
y2 - y1/x2 - x1 = m
-4 - (-8)/3 - 1 = m
8 - 4/3 - 1 = m
4/2 = m
m = 2
3.) H
y2 - y1/x2 - x1 = m
-3 - (-6)/-4 - 2 = m
6 - 3/-6 = m
3/-6 = m
-1/2 = m
4.) A
m = -2

-6(8k+9c)-3 use c=2 and k=9
Answer:
-543
Step-by-step explanation:
For every value of k, you substitute 9 and for every value of c, you substitute 2
-6((8x(9)+ 9(2)) - 3
so order of operations says you should do what's in the parentheses first.
8 x 9= 72 and 9 x 2 = 18
so now you have -6 ( 72 + 18) -3
Finish the calculating inside the parentheses: -6 (90) -3
and now multiply -6 and 90 before you subtract 3
-6 x 90 = -540
-540 - 3 = -543
