Answer:

  13 costumes

Step-by-step explanation:

The amount of fabric used is the product of the amount per costume and the number of costumes.

  A = na . . . . . A = total area; n = number of costumes; 'a' = area per costume

  46 2/3 = n(3 1/2)

  n = (46 2/3)/(3 1/2) = (140/3)/(7/2) = (140/3)(2/7) = 40/3 = 13 1/3

Apparently there is some waste, as Emerson used more fabric than necessary to make 13 costumes.

Answer:

Step-by-step explanation:

Let Eva's height be x

62* 0.5 = x + 1.5

31 = x + 1.5                   Subtract 1.5 from both sides.

31 - 1.5 = x

x = 29.5

Eva is 29.5 inches tall.

Answer:

$94105.81

Step-by-step explanation:

[tex]21000( ({1 + .0512675})^{30} - 1) \\ = 73105.81 \\ 73105.81 + 21000 = 94105.81[/tex]

Future value of the investment if the interest is compounded daily is $94,105.80.

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

Given that,

Principal amount, P = $21,000

Rate of interest, r = 5% = 5/100 = 0.05

Time, t = 30 years

The final amount in a compound interest is,

A = P (1 + r/n)^(nt), where n is the number of times compounding is done in a year.

Here, n = 365

A = 21000 (1 + 0.05/365)^(365 × 30)

  = 94,105.802

  ≈ 94,105.80

Hence the final amount is $94,105.80.

Answer:

a)   Number of laundry he can do with this box  = 78 laundries.

b)   Price he paying for each load =  0.256 $

Step-by-step explanation:

Total scoop contained in detergent box = 195 scoops.

 Scoops used by each load of laundry = 2 1/2 = 2 * 2 + 1/2 = 5/2 scoops = 2.5 scoops

 Number of laundry he can do with this box = 195/2.5 = 78 laundries.

Price of detergent box = 19.99 $

Price he paying for each load = Total price/ Number of loads

 = 19.99/78

= 0.256 $

Evaluating an algebraic expression is the process of determining the value of an expression when a specified integer is used to replace a variable.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)

An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) You can think of expressions as being comparable to phrases. A phrase in language may contain an action on its own, but it does not constitute a whole sentence.

In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.). Terms comprise expressions.

Answer:

  f^-1(x) = ∛((x +5)/2)

Step-by-step explanation:

Continue to solve for y.

  [tex]x +5=2y^3\qquad\text{so far so good}\\\\\dfrac{x+5}{2}=y^3\qquad\text{divide by 2}\\\\\sqrt[3]{\dfrac{x+5}{2}}=y\qquad\text{take the cube root}\\\\\boxed{f^{-1}(x)=\sqrt[3]{\dfrac{x+5}{2}}}\qquad\text{expressed in functional form}[/tex]

If you want to "rationalize the denominator", you can multiply both numerator and denominator by 4 inside the radical. This will simplify to ...

Answer:

your answer would be 0.25 cents per egg

Step-by-step explanation:

72 is answer

as it got down by 4% every year

in 2011 it was 75 means in the next year it will be 75-(75*4/100) that is equal to 72

The robbery rate in year 2012 was 72.

A percentage is a number or ratio that can be expressed as a fraction of 100.

Given that in a city that robbery rate was 75 in 2011 was 75, and then went down by 4% in 2012.

We need to find the robbery rate of the city in 2012.

So, here went down means it decreased by 4%,

That mean, now the robbery rate will be (100-4) = 96% of 75.

Therefore, the robbery rate in year 2012 was =

0.96 x 75 = 72

Hence the robbery rate in year 2012 was 72.
