THE ANSWER IS FALSE IM PRETTY SURE

Answer:

True

Step-by-step explanation:

All radii are half of a diameter.

Answer:

20%

Step-by-step explanation:

We can start by looking at it as a ratio, so 4 divided by 20 and 4/20 = 0.2, so that would be 20% viewing 1=100%.

Another way is

20 here is 100%, and for 20 to equal 100, we have to multiply it by 5. To balance it out, multiply the top by 5 as well, and 4 * 5 =20. Therefore, 4/20 = 20%

Answer:

Step-by-step explanation:

How many four-digit personal identification numbers (PIN) are possible if the PIN cannot begin with a 0 and the PIN must be an odd number?

ANSWER B: 4,500

The number of 4 digit personal identification numbers (PIN) is 4500

A PIN is a security code that is used for verifying identities

There are 10 numerical digits i.e. 0 - 9

Since the 4 digit personal identification numbers (PIN) cannot begin with 0, then the first character can take any of 9 digits

The other three characters can take any of the 10 digits.

So, the number of PIN is:

PIN = 9 * 10 * 10 * 10/2

Expand

PIN = 4500

Hence, the number of 4 digit personal identification numbers (PIN) is 4500

The exact value of tan(105°) is -2 - √3.

Tangent function of an angle in a right angled triangle is defined as the ratio of the opposite side to the adjacent side.

Given that, we have to find the exact value of tan(105°).

We know that,

105° = 60° + 45°

tan(105°) = tan (60° + 45°)

We know,

tan (A + B) = (tan A + tan B) / (1 - tan A tan B)

So,

tan (60° + 45°) = (tan 60 + tan 45) / (1 - tan (60) tan (45))

tan 60 = √3 and tan 45 = 1

tan (60° + 45°) = (√3 + 1) / (1 - √3)

Multiplying both numerator and denominator by (1 - √3),

                        = (√3 + 1)² / (1 - 3)

                        = -(3 + 2√3 + 1) / 2

                        = -(4 + 2√3) / 2

                        = -(2 + √3)

                        = -2 - √3

Hence the value of tan(105°) is -2 - √3.

Answer:

500

Step-by-step explanation:

Let there were a total of x number of customers.

As 125customers choose chocolate flavor as their favorite which is 25% of the total customers surveyed, so

25% of x = 125

0.25x=125

x=125/0.25=500

Therefore, the total number of customers surveyed is 500.

__________________________________________________________

The value of "c" is 4.

Here's why.

__________________________________________________________

[tex]60-\left(3\cdot c+4\right)=4\cdot\left(c+6\right)+c[/tex]

What does c equal???

__________________________________________________________

Let's try using all numbers to find out what it is

[tex]60-\left(3\cdot 4+4\right)[/tex] = [tex]44[/tex]

[tex]4\cdot\left(4+6\right)+ 4[/tex] = [tex]44[/tex]

So it's 4!

Answer:

(3,8) and (5,12) in other words C.

Step-by-step explanation:

Answer:

Part A) x = -3

Part B) x = 1, x = -7

Part C) x < -7

Part D) 2

Step-by-step explanation:

2(x - 3) = 3x - 3

open the parenthesis

2 * x - 2 * 3 = 3x - 3

2x - 6 = 3x - 3

subtract 2x from both sides

2x - 2x - 6 = 3x - 2x - 3

-6 = x - 3

add 3 to both sides

-6 + 3 = x

-3 = x

|2x + 6| = 8

split this into two equations:

2x + 6 = 8

&

2x + 6 = -8

2x + 6 = 8

2x = 8-6

2x = 2

x = 1

2x + 6 = -8

2x = -8 - 6

2x = -14

x = -7

-5(x + 1) > 30

open the parenthesis

-5x - 5 > 30

add 5 to both sides

-5x > 35

divide both sides by -5

x > -7

since you divided by a negative, flip the sign.

x < -7

f(x) = 4x - 3

substitute x for 5

5 = 4x - 3

5 + 3 = 4x

8 = 4x

2 = x

Answer:

what triangle????????????????????????????

Answer:

x = 10,000

Step-by-step explanation:

commision earned = $4500. - $4200

commision = 300

therefore:

commision = 3% of the amount of the sales

300 = 3% of x( the price isn't known)

300 = 3/100 * x

300 = 3x /100

multiplying both sides by 100

300 x 100 = 3x/100 x 100

30000 = 3x

Divide through by 3

x = 10,000.

the amount of the sales = 10,000

______________

To check

commision = 3% of 10,000

commision = 300
