Answer:

1.28 * 10^10

Step-by-step explanation:

Area Code:  8 * 2 * 10

7 digit number: 8 * 10 * 10 * 10 * 10 * 10 * 10

The total number of area codes is 160

8,000,000 * Area Codes

1.28*10^10

Answer:

18i, -7-i, -6+18i

Step-by-step explanation:

1. √-324

first take out the negative as √-1=i

√-324= i√324

324 =2*162

324=2*2*81

324=2*2*9*9

i√324=i√2*2*9*9= i* 2*9= 18i

3.

-4+7i-3-8i combine like terms

-4-3 -8i+7i = -7-i

5.

(1+5i)(4-2i) distribute

1*4 -1*2i +5i*4 -5i*(-2i) multiply

4 -2i +20i +10i² but i²= -1 so

4 -2i +20i -10 combine like terms

-6 +18i

Answer:

Equation can be used to find  the number of candles (c) Katie ordered is 54 = 3c + 6 .

Option (C) is correct .

Step-by-step explanation:

A. 3c = 54

B. 6c = 54

C. 3c + 6 = 54

D. 3c – 6 = 54

As given

Katie ordered candles that cost $3 each from a website.

She was charged a flat shipping fee of $6 and no sales tax.

If she spent a total of $54,

c represented the number of candles .

Equation becomes

Total cost = Cost per candle + Flat shipping fee

54 =  3 × c + 6

54 = 3c + 6

Equation can be used to find  the number of candles (c) Katie ordered is 54 = 3c + 6 .

Option (C) is correct .

Answer:

$1361.68

Step-by-step explanation:

15000 > 10000

so she gets the 8.5%

so she gets 108.5% of her salary

x/1255 = 108.5/100

1255(108.5) = 136,167.5

136,167.5/100 = 1361.68

Answer:

The answer is b (1,11)

Step-by-step explanation:

You can graph the lines and find the solution that way (which is where the lines intersect)

or you can algebraically solve.

To check this, you can basically plug in the x and y values for the equation and see if they match with what the equation equals..

Example:

10x + 3y = 43

-9x - y = -20

10(1) + 3(11) --> 10 + 33 = 43.. 43 equals 43

-9(1) - (11) = -9 - 111 = -20.. -20 equals -20

(the values match up so it's a solution)

[tex]s.p. = c.p. \times 5\% \\ or \: x = 400 \times 5 \div 100 \\ or \: x = 4 \times 5 = 20 \\ [/tex]

Given:

The first four numbers in a pattern are 4, 2, 1, and 0.5.

To find:

The next three numbers in the pattern.​

Solution:

We have a pattern,

4, 2, 1, 0.5

Clearly, it is a GP and the common ratio is [tex]\dfrac{1}{2}[/tex] because each term is half of its preceding term.

Next term after 0.5 = [tex]0.5\times \dfrac{1}{2}=0.25[/tex]

Next term after 0.25 = [tex]0.25\times \dfrac{1}{2}=0.125[/tex]

Next term after 0.125 = [tex]0.125\times \dfrac{1}{2}=0.0625[/tex]

Therefore, the next three numbers in the pattern are 0.25, 0.125 and 0.0625 respectively.

Answer: 42.5

Step-by-step explanation:

3x + x+10 + G = 180

4x + 10 = 180

4x = 170

x = 42.5

Step-by-step explanation:

Since this is an isosceles triangle, the angle at G is the same as the angle at P. Thus G=(x+10)°.

Remembering that the sum of a triangle adds up to 180°.

Therefore,

3x + (x+10) + (x+10)=180.

5x + 20 = 180

5x = 160

x=32

Remember, G=x+10

G= 32+10

G=42°

Answer:

The Royal Fruit Company produces two types of fruit drinks. The first type is 70%

pure fruit juice, and the second type is 95%

pure fruit juice. The company is attempting to produce a fruit drink that contains 75%

pure fruit juice. How many pints of each of the two existing types of drink must be used to make 90

pints of a mixture that is 75%

pure fruit juice?

Step-by-step explanation:

To make the desired drink we need to add 30 pints of  95% of the drink, and  80 pints of 40% of the drink.

Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m3), a derived unit, is the SI unit of volume. Volume is another word for capacity.

Given, The Royal Fruit Company produces two types of fruit drinks. The first type is 40% pure fruit juice, and the second type is 90% pure fruit juice.

Let,

a = Volume of 40% of drink

b = volume of 95% of drink

Since the two existing types of drink must be used to make 110 pints of a mixture that is 55% pure fruit juice

a + b = 110

0.4a + 0.95 b = 110 * 0.55

Comparing these equations we will get,

a = 80

and b = 30

Therefore, To make the desired drink we need to add 30 pints of  95% of the drink, and  80 pints of 40% of the drink.

Answer:

28 + 8y - 8

Step-by-step explanation:

According to the problem;

-2(3x + 12y - 17x - 16y + 4)

Collecting like terms;

-2(3x -17x + 12y - 16y + 4)

-2(-14x - 4y + 4)

28 + 8y - 8

None of the options matches the correct answer.

Answer:

45

Step-by-step explanation:

The value of f(-4) in the polynomial functions f(x) = 2x² - x + 9 is 45

The function is given as:

f(x) = 2x² - x + 9

Substitute -4 for x

f(-4) = 2(-4)² - (-4) + 9

Evaluate the exponents

f(-4) = 2(16) - (-4) + 9

Evaluate the product

f(-4) = 32 - (-4) + 9

Evaluate the sum and the difference

f(-4) = 45

Hence, the value of f(-4) is 45

BC=3x-4=3*5-4=15-4=11

AB=2x+1=2*5+1=10+1=11

AC=AB+BC=11+11=22

Step-by-step explanation:

Answer:

x = 18

Step-by-step explanation:

2x + 5 + 17 = 3x + 4

2x + 22 = 3x + 4

2x + 22 - 22 = 3x + 4 - 22

2x = 3x - 18

2x - 3x = 3x - 18 - 3x

-x = -18

-x / -1 = -18 / -1

x = 18

Answer:

The rule of the translation will be:

(x, y) → (x+3, y+5)

Step-by-step explanation:

Translation of an object is basically termed as "sliding" the original. If the image is moved right by the 'c' units, the 'c' unit(s) are added to the x-coordinate and if the image is moved left by the 'c' units, the 'c' unit(s) are subtracted to the x-coordinate.

And If the image is moved up by the 'c' units, the 'c' unit(s) are added to the y-coordinate and if the image is moved down by the 'c' units, the 'c' unit(s) are subtracted to the x-coordinate.

As the point is (4, 2)

The image of the point is (7, 7)

As the coordinates of the image point indicate that 3 units are added to the x-coordinate of the original point, and 5 units are added to the ý-coordinate.

Hence, the image will be move 3 units to the right and 5 units up.

Therefore, the rule of the translation will be:

(x, y)  →  (x+3, y+5)

as

(4, 2) →  (x+3, y+5) = (4+3, 2+5) = (7, 7)
