100% is $1.00

If you add three times that, you get the answer.

300%

Step-by-step

300% of 1.00$ is 4.00 because you are adding 1.00 + 300%

How many 4 digit multiples can not be divided by 5

Advocard [28]

Answer:

1800

Step-by-step explanation:

Let us solve this question by Modular Airthmatic.

Let the lowest 4 digit number be X.

X= 1 (mod 5)

X =2 (mod 5)

X=3 (mod 5)

X =4 (mod 5)

X=1+5 t where t is any integer.

1+5 t=2 (mod 5)

5 t=1 (mod 5 )

5 is the Modular Inverse of modulo 5

t=1 (mod 5)

t =1+5 u : u= any integer.

X becomes 1+ 5 (1+5u )=6+25 u

6+25u =3 (mod 5)

25 u= -3 (mod 5)=2 (mod 5)

25 is Modular Inverse of Modulo 5

u=2 (mod 5)

u =2+5 v : v= any integer.

X becomes 6 +25 (2+5 v)=56+125 v .

56 +125 v=4 (mod 5)

125 v=-52 (mod 5)=3 (mod 5)

125 is Modular Inverse of modulo 5

v = 3 (mod 5)

v =3 +5 w where w is any integer.

For lowest 4 digit number, take

w=200

X=1003 : Lowest 4 digit number.

Take w=201

X=208 : Next number.

For 4 digit largest number, take

w=1995

X= 9978 : Largest number.

No. of Numbers =(1995 - 200 )+1=1800 □Ans.

An arithmetic sequence has a1 = 22 and a8 = 43. Find a15.

brilliants [131]

The 15th term of the arithmetic sequence $a_{15} = 64$

Option B is correct

The nth term of an arithmetic sequence is given as:

$a_{n} = a + (n - 1)d$

The first value, a = 22

$a_8 = a+(8 - 1)d\\a_8 = a + 7d$

Since $a_8 = 43$

$43 = 22 + 7d\\7d = 43 - 22\\7d = 21\\d = \frac{21}{7}\\d = 3$

The common difference, d = 3

$a_{15}= a + (15-1)d\\a_{15} = a + 14d\\a_{15} = 22 + 14(3)\\a_{15} = 22 + 42\\a_{15} = 64$

The 15th term of the arithmetic sequence = 64

Graph f(x)=3x+5 and g(x)=3x-2

IgorLugansk [536]

Answer:

Two parallel lines

Step-by-step explanation:

the slopes are the same: slope = 3

f(x) 3x + 5 g(x) = 3x - 2

Pick at least three x values and find their corresponding values for y. Remember the f(x) and g(x) represent y

f(x) = 3x + 5 g(x) = 3x - 2

y = 3x + 5 y = 3x - 2

let x = 0 y = 3(0) + 5 y = 3(0) - 2

y = 5 y = -2

Ordered pair (0, 5) (0, -2)

Let x = 1 y = 3(1) +5 y = 3(1) - 2

y = 8 y = 1

ordered pair (1, 8) (1, 1)

Let x = -1 y = 3(-1) + 5 y = 3(-1) - 2

y = 2 y = -5

ordered pair (-1, 2) ( -1, -5)

Locate the ordered pairs and draw the graph on the lines.

you will graph two parallel lines

Find the measure of the are or central angle indicated. Assume that lines which appear to be

Afina-wow [57]

Answer:

major arc CEB = 320°

Step-by-step explanation:

arc BF = 140°

arc CE = 140°

arc CB = arc EF

arc CB + arc EF = 360-280 = 80

arc CB = 40°

major arc CEB = 360 - 40= 320°
