whats 12% in a fraction and decimal

Answer:

Step-by-step explanation:

if the item is 430, and the sales tax is 25.80

we can find how much is 1%

430/100=4.30

25.80/4.30=6

the sales tax is 6%

x + 54 + 5x = 90°

6x = 90 - 54

6x = 36

x = 36/6 = 6

value for x is 6

Answer:

Given the function: y=f(x) = 3x+2

when x=-2 at the beginning of the interval [-2, 5],

then;

y = 3x+2 begins at

y= 3(-2)+2 = -6+2= -4.

and

when x=5 at the end of the interval [-2, 5],

y = 3x+2 ends up at

y= 3(5)+2 = 15+2= 17.

So,

y has changed -4 to 17, which is a change of 17-(-4)= 17+4 = 21

and x has changed from -2 to 5, which is a change of 5-(-2)=5+2=7

So, the average rate of change of y with respect to x over the interval

[-2, 5] is given by ;

=

Therefore, the average rate of change y with respect to x over the interval is, 3

Answer:

K = $0.45

1____ 2__ 4 __5___10__ 15__ 20__ 100

0.45_0.9_1.8_2.25_4.5_6.75__9___45

Step-by-step explanation:

Given the data:

Number of pepper: 1 2 4 5 10 15 20 100

Cost :

Cost of 5 pepper = 2.25

Using variation :

Cost = number of pepper * k

K = CONSTANT of proportionality

k = cost / number of pepper

k = 2.25 / 5

k = 0.45

Hence,

Cost of pepper = k * number of pepper

Number of pepper:

Cost :

Answer:the second one

Step-by-step explanation:

y1= log 3 etc so it the second one

The correct system of equations which can represent the equation are,

⇒ y₁ = log (x + 3) / log 4

⇒ y₂ = log (2 + x) / log 2

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ log₄ (x + 3) = log₂ (2 + x)

Now, We know that;

The formula is,

logₐᵇ = log b / log a

Hence, By using above rule we get;

The correct system of equations which can represent the equation are,

⇒ log₄ (x + 3) = log (x + 3) / log 4

⇒  log₂ (2 + x) = log (2 + x) / log 2

Thus, The correct system of equations which can represent the equation are,

⇒ y₁ = log (x + 3) / log 4

⇒ y₂ = log (2 + x) / log 2

Answer:

143π in³

Step-by-step explanation:

A basketball has the shape of a sphere

Volume of a basketball = 4/3πr³

Diameter = 9.5 in

Radius = diameter/2

= 9.5/2

= 4.75 in

Volume of a basketball = 4/3πr³

= 4/3 * π * 4.75³

= 4/3 * π * 107.17

= (4*π*107.17) / 3

= 428.68π / 3

= 142.89π in³

Approximately

143π in³ to the nearest whole number

Divide 12 by 6.

Answer:

b. x > -6

Step-by-step explanation:

> [greater than], and < [less than] inequalities are not filled in because the value is not included, but is only greater or less than.

≥ [greater than or equal to], and ≤ [less than or equal to] inequalities are filled in because the value is included, and it is greater than or less than.

Given that there is an empty circle with an arrow moving in the positive direction from -6, the inequality must be a greater than, and since the value is -6, x > -6.

Answer:

when you do these types of problems, try to think of how you could find out if they are similar. Try to make the shapes bigger or rotate. ^^

i hope this wasn't too much into and i hope this helped <3

edit: the answer is 1 and 2.

the reasoning is when you turn the rectangle and divide each correlating side (7.5 by 5 and 9 by 6) for both sides you get the same number: 1.5

when you get the same number, they are similar ^^

Answer:

  rectangles 1 and 2 are similar

Step-by-step explanation:

Polygons are similar when ...

In a rectangle, all angles are 90°, so all angles are congruent.

The question of proportionality can be answered a couple of ways. One is to identify corresponding sides in the different figures, then see if the ratios between figures are the same.

Another way is to identify corresponding sides in the same figure, find their ratios, then see if those match with the ratios in the other figure.

For triangles and parallelograms, it can be useful to use the ratios of the sides in order from shortest to longest.

Here, the ratios are ...

  rectangle 1: 5 : 6

  rectangle 2: 7.5 : 9 = 15 : 18 = 5 : 6 . . . . similar to rectangle 1

  rectangle 3: 12 : 15 = 4 : 5 . . . . not similar to the others

Rectangles 1 and 2 are similar.

_____

Additional comment

Ratios are equivalent if all the numbers involved have the same factor. For rectangle 2, we wanted to reduce the ratio to the lowest integer terms. Here, we recognize that 7.5 can be cleared of a decimal by multiplying by 2, so we did ...

  7.5 : 9 = (2)(7.5) : (2)(9) = 15 : 18

Now, we can see that these numbers have 3 as a common factor, so we can remove that factor.

  (3)(5) : (3)(6) = 5 : 6 . . . . reduced form of the ratio 7.5 : 9.

__

We can also get there by finding the greatest common divisor* of 7.5 and 9. That is 1.5, so we have ...

  7.5 : 9 = (1.5)(5) : (1.5)(6) = 5 : 6

__

* Euclid's algorithm for finding the GCD works with decimals or fractions as well as integers. Basically, you see if the difference is a divisor of the numbers. If it is, that is the GCD. 9 -7.5 = 1.5 is a divisor of both 7.5 and 9, so that is the GCD. (If not; the difference replaces the larger number, and the process repeats.)

Answer:7w+10x

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

the angle that is equal to 57 and angle y are supplementary angles meaning that the two values added together will equal 180. So all you have to do is subtract 57 from 180 to get 123. So y = 123

Answer:

15 miles per hour

Step-by-step explanation:

Since we're looking for miles per hour ([tex]\frac{miles}{hour}[/tex]) we can just replace the variables in the fraction. So, 210 divided by 14.

[tex]\frac{210}{14} \\=15 miles per hour[/tex]

Answer:

9, 2, 0

Step-by-step explanation:

Solving the inequality

24 > 2(x + 2) ← divide both sides by 2

12 > x + 2 ( subtract 2 from both sides )

10 > x

Thus we require values of x that are less than ( but not equal to ) 10

These are 9, 2 and 0

Answer: The tower's shadow is 60 feet long.

Step-by-step explanation:

We can use a ratio to solve this:

24/45 = 32/x

Cross multiply: (Numerator of left side times the denominator of right side, and denominator of the left side by numerator of right side.)

24x = 32(45)

24x = 1440  divide both sides by 24

x = 60

In this case, Kiran says that -2 is less than -5. However, if you look at a number line (in which the further left it is, the smaller the digit in value, while to the right, the greater the value), -5 is found to the left of -2. Therefore, -2 > -5.

Answer:

A = $9,760.00

Step-by-step explanation:

I = A - P = $1,937.50

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 3.875%/100 = 0.03875 per year.

Solving our equation:

A = 10000(1 + (0.03875 × 5)) = 11937.5

A = $11,937.50

The total amount accrued, principal plus interest, from simple interest on a principal of $10,000.00 at a rate of 3.875% per year for 5 years is $11,937.50.
