hi i have problems with some of my mathematic question if you are super good in maths pls kindly send a message or comment so we can work it out together ...thanks in advance​

Answer:

$0.44

Step-by-step explanation:

12.98/30 is 0.4326666

Rounded to the nearest cent is $0.44

Answer:

5 minutes costs 5.20 10 minutes cost 7.20 $20 gets you 42 minutes

Step-by-step explanation:

for 5 and 10 multiply the number of minutes by the price per minute then add 3.2 base fee.  5*.4=2 +3.2=5.2      10*.4=4 +3.2=7.2

For $20 subtract the 3.2 base fee (16.8) and divide that by the .4 a minute fee to get 42 which would be 42 minutes.

I think it is [9]

srry if im wrong I tried

Step-by-step explanation:

Answer:

Step-by-step explanation:

s = rθ, where r is the radius, θ is the radian measure of the central angle, and s is the arc length.

4.5 = 2.5θ

4.5 / 2.5 = θ

1.8 = θ

Answer:

16

Step-by-step explanation:

it is not  728728827632788763728 that is wrong it is 100 divided by 10 =10

160 divided by 10 =16

Answer:

The area will be 113.1

hope it helps u

have a great day

Answer:

16=2b+4

12=2b

b=6

.............

Answer:

b = 6

Step-by-step explanation:

16 + 5b = 7b + 4     <-- Subtract 5b from the left

16 = 2b + 4     <-- Subtract 4 from the right

12 = 2b     <-- Divide by 2

b = 6

22 miles

Step-by-step explanation:

Answer:

x² + 18x +81

x² - 14x +49

4x²- 4x - 1

Step-by-step explanation:

multiply the x in the first parentheses by x and 9 in the other parentheses and

multiply the 9 in the first parentheses by x and 9 in the other parentheses and add all together

(x+9)(x+9)

x² + 9x + 9x + 81

x² + 18x +81

multiply the x in the first parentheses by x and -7 in the other parentheses and multiply the -7 in the first parentheses by x and -7 in the other parentheses and add all together

(x-7)(x-7)

x² -7x - 7x +49

x² - 14x +49

(2x-1)² is the same as (2x-1)(2x-1)

multiply the 2x in the first parentheses by 2x and -1 in the other parentheses and multiply the -1 in the first parentheses by 2x and -1 in the other parentheses and add all together

(2x-1)(2x-1)

4x²-2x-2x+1

4x²- 4x - 1

Answer:

constant of variation

Step-by-step explanation:

Constant of variation and constant of proportionality mean the same and they are used in variations.

For instance:

[tex]y = 2x[/tex]

In the above equation, y varies directly as x and the constant of proportionality or variation is 2.

It is often represented with k (though, other alphabets can also be used)

Answer:

2

Step-by-step explanation:

y2-y1 = 5-1 =4

x2-x1= 2-0 =2

4/2=2

Step-by-step explanation:

[tex]m = \frac{y2 - y1}{x2 - x1} \\ = \frac{5 - 1}{2 - 0} \\ = \frac{4}{2} \\ = 2[/tex]

Answer:

The answer is 23

Step-by-step explanation:

Plug in the value of m=2 into the equation.

7(2)+9=?

Then solve.

14+9=?

Then, you'll get your answer of 23

Answer:

25/30 and 28/30

Step-by-step explanation:

1. To find the least common denominator, you need to find the least common multiple of the two denominators which are 6 and 15. Prime factorization of these numbers gives:

6 = 2 x 3

15 = 5 x 3

A number that would evenly divide both 6 and 15 must contain 2 x 3 x 5 which is 30.

Thus 30 is the least common denominator.

2. Now we need to somehow change both fractions to make them have a denominator of 30. To do this we can multiply by fractions with same numerator and denominator since that would be like multiplying by 1.

So, 5/6 x 5/5 = 25/30

And 14/15 x 2/2 = 28/30

Answer:

25/30 and 28/30

Answer:

[tex]x(3x + 2) = 3x^2 + 2x[/tex]

Step-by-step explanation:

Given

[tex]x(3x + 2)[/tex]

Required

Apply distributive property

[tex]x(3x + 2)[/tex]

Distribute

[tex]x(3x + 2) = x * 3x + x * 2[/tex]

[tex]x(3x + 2) = 3x^2 + 2x[/tex]

Answer:

[tex]no \: solution[/tex]

Step-by-step explanation:

1) Expand.

[tex]7a + 5a + 15 = 8a + 4a+ 8[/tex]

2) Simplify 7a + 5a + 15 to 12a + 15.

[tex]12a + 15 = 8a + 4a+ 8[/tex]

3) Simplify 8a + 4a + 8 to 12a + 8.

[tex]12a + 15 = 12a + 8[/tex]

4) Cancle 12a from both sides.

[tex]15 = 8[/tex]

5) Since 15 = 8 is false, there's no solution.

[tex]no \: solution[/tex]

Therefor, this equation has no solution.

Step-by-step explanation:

slope =  

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y + 3 = (x - 2) is in this form

with slope m =

Answer:

-x is the slope

Answer:The first table would be a proportional relationship.

Step-by-step explanation:

It's the only table with a constant, which is required in a proportional relationship. The constant would be 1300 which you can find by divided the two numbers in each row.
