Step-by-step explanation:

4x+3x-5+2x+5=180 (to find x)

9x=180

x=20

Therefore DEF=AEC(vertically opposite angles are equal)

AEC=DEC

=4x +3x-5

=4(20)+3(20)-5

Answer:

acute angles... I think 35

Angle A: 56 degrees.

Angle B: 34 degrees.

Angle C: 56 degrees.

Angle D: 124 degrees.

Step-by-step explanation:

Angle A = 180-124, or 56 degrees.

The right angle given plus Angle B must equal 124, so 124-90 = 34 degrees.

Angle B = 34 degrees.

Angle C = 180-124, or 56.

Answer:

4 (rounded to the nearest whole number)

Step-by-step explanation:

total height = 3 x 2 = 6

Volume = radius^2 * pi * height

75.36= radius^2 * pi * 6

75.36/pi = radius^2 * 6  

23,987833 = radius^2 * 6

23,987833/6 = radius^2

3,997972 = radius^2

radius = 1,999493

diameter = radius x 2 = 1,999493 x 2 = 3,998986

Social Loafing

Step-by-step explanation:

In social psychology, social loafing is the phenomenon of a person exerting less effort to achieve a goal when they work in a group than when working alone. It is seen as one of the main reasons groups are sometimes less productive than the combined performance of their members working as individuals.

The event is an example of a combination.

It is an arrangement of a set of numbers from a total set where the order of the set is not relevant.

We have,

This event is an example of a non-replacement or non-independent event.

In probability theory, an event is said to be non-replacement or non-independent if the outcome of a previous event affects the outcome of the current event.

In this case,

Once a name is pulled out of the hat, it is not replaced, meaning that the probability of pulling out a certain name changes with each draw.

For example, if a name is pulled out of the hat, the probability of pulling out that same name again decreases because it is no longer in the hat.

Therefore,

This event is non-replacement or non-independent.

Answer:

x > 10.5

Step-by-step explanation:

The point is on 10.5

The point is open which means that 10.5 is not included in the solution and we will be using < or >

The line is pointing towards numbers that are greater than 10.5 Which means that x is greater than 10.5

Hence, the answer is x > 10.5

Answer:

down below.

Step-by-step explanation:

One–third of the product of −8 and 9 = -24

-8(9) = -72

-72 / 3 OR -72(1/3) = -24

Half the sum of 8 and −6 = 1

8 + (-6) =2

2 / 2 = 1

Three times the sum of 12 and −6 = 18

12 + (-6) = 6

6 * 3 = 18

One-fifth the product of 1 and −5 = -1

1(-5) = -5

-5/5 = -1

Five times the sum of −8 and 4 = -20

-8 + 4 = -4

-4 * 5 = -20

Answer: step one is correct and the second step is incorrect

Step-by-step explanation:

Answer:

Betsy isn't correct. Betsy's calculations are wrong as she made her calculations by multiplying the base number of customers by 3 and then summing it all up for the 4 years under review instead of a continuous multiplication by 3.

Step-by-step explanation:

26 × 3 × 4 is different from 26 × 3⁴

- If Betsy meets her target for the next 4 years, she will have 2106 customers in 4 years time.

- Betsy started her business 2 years ago.

- In the first year, Betsy has 8 customers.

- In the second year, Betsy added 18 customers,

- So, her customers are now 8+18 = 26

- Betsy's goal is that in each of the next 4 years, she will have three times as many customers as the year before.

If the base number of customers is truly 26 this year,

Next year, Betsy would have 26 × 3 = 78 customers.

In 2 years, she would have 78 × 3 = 234

Thus indicating that in t years from now, the number of her customers will be

N(t) = N₀ × 3ᵗ

where

N(t) = number of customers t time from now

N₀ = number of customers at the moment = 26

t = number of years from now.

N(t) = 26 × 3ᵗ

In 4 years from now, Betsy will have

N(t=4) = 26 × 3⁴ = 2,106

So, it is evident that Betsy's calculations are wrong as she made her calculations by multiplying the base number of customers by 3 and then summing it all up for the 4 years under review instead of a continuous multiplication by 3.

26 × 3 × 4 is different from 26 × 3⁴

- If Betsy meets her target for the next 4 years, she will have 2106 customers in 4 years time.

Answer:

[tex]\sqrt{18.04}[/tex]

Step-by-step explanation:

The wording is a bit confusing, but i beleive it basically means that we're trying to find the length on a leg of a triangle with a leg length of 3 and a hypotenuse of 5.2

if we write this out as an equation, it gives us:

[tex]5.2^{2}-3^{2}[/tex]

If we then simplify this, we get 27.04 - 9, which then simplifies to 18.04.

We then need to get the square root of this number to get the answer, thus the answer is [tex]\sqrt{18.04}[/tex]
