explain and demonstrate how to turn 4/20 into a percent
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%

What is the slope and y-intercept of -2y = -x + 6
Answer:
Slop= 1/2 (fraction not division just to make sure you know that ;-;)
Y intercept = ( 0,-3)
Step-by-step explanation: I can't really explain it since I did this years ago in 8th grade but just search up the step by step or watch a video about intercepts
Answer:
slope: 1/2
y-intercept: -3
Step-by-step explanation:
slope= rise over run of 2 points
(0,-3) and (6,0) are the points
We go up on the y axis 3 units
We go right on the x axis 6 units
rise/run= 3/6
3 ÷ 6= 0.5 or 1/2

A insurance salesperson earns a salary of $4,200 per month plus a commission of 3% of sales. How much must the salesperson have to sell to make an income of at least $4,500?
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

base of the pole. How long is the wire?
O 9.4
09.0
O 89.0
O 13
Answer:
your answer would be 9.4
Step-by-step explanation:
you'd have to plug in the numbers in the equation.
8^2 + 5^2 = c^2
64 + 25 = c^2
89 = c^2 then you'd do the square root of 89 which will give you 9.4 when rounded to the nearest tenth.

The local ice cream shop surveyed the customers to see which flavor of ice cream is most popular 125 people choose chocolate as their favorite which represents 25% of the customers surveyed how many total customers were surveyed A.425 B.20 C.500 D.32
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.

What is the exact value of tan(105°).
2 +V3
-2+V3
2-√3
-2-√3
The exact value of tan(105°) is -2 - √3.
What is Tangent function?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.

The value of "c" is 4.
Here's why.

PLEASE HELP FAST! I'LL LIST U BRAINIEST IF U ANSWER RIGHT!
Part A: Solve the following equation: 8 + 2(x - 3) = 3x - 3 (2 points)
Part B: Solve the following absolute value equation: |2x + 6| = 8 (4 points)
Part C: Solve the following inequality: -5(x + 1) > 30 (2 points)
Part D: f(x) = 4x - 3. Find f(5) (2 points)
Answer:
Part A) x = -3
Part B) x = 1, x = -7
Part C) x < -7
Part D) 2
Step-by-step explanation:
Part A)
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
Part B)
|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
Part C)-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
Part D)
f(x) = 4x - 3
substitute x for 5
5 = 4x - 3
5 + 3 = 4x
8 = 4x
2 = x

a. 5,000
b. 4,500
c. 3,600
d. 500
Answer:
BStep-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
What is a PIN?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
