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

Answer:

f(x) = 9x+8

Step-by-step explanation:

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

just remeber a penny is 1 cent a qurter is 25cents and so on

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

Answer:

Thus: m=14°, n=28°

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 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°

Answer:

$172.46

Step-by-step explanation:

Discount = 229.95 × 25/100

Discount = 229.95 x 0.25

= $57.49

Final Price = 229.95 - 57.4875

= $172.46

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

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].

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:

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

Answer:

LP = 18

Step-by-step explanation:

Given that,

In ΔLPN,

LQ = 6, LM = 11 and MN = 22

We need to find the length of LP.

As QM ║PN, let QP = x

[tex]\dfrac{LQ}{LP}=\dfrac{LM}{LN}\\\\\dfrac{6}{6+x}=\dfrac{11}{11+22}\\\\\dfrac{6}{6+x}=\dfrac{11}{33}\\\\198=66+11x\\\\198-66=11x\\\\132=11x\\\\x=12[/tex]

LP = 6+x

= 6+ 12

= 18

Hence, the length of LP is 18.

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

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.
