What is the value of the expression when a = 6, b = 4,and c = 8?

1 answer:

6 0

The answer is: [B]: 3.
______________________________________________
Let us assume that the problem is meant to be written as:
_______________________________________________
2a / (3b - c) ;

Explanation:
___________________
we are given the values for "a", "b", "c" ; and we are asked to solve the problem when the given values:
a = 6, b = 4; and c = 8 .
________________________
Note:
________________________
We have a "numerator" , " 2a " ; and a "denominator" , (3b - c).
_______________________
Let us start by finding the numerator:
_________________________________
Numerator: 2a = 2*a = 2 * 6 = 12.
_______________________________________
Denominator: 3b - c = (3*4) - 8 = 12 - 8 = 4
_______________________________________
To solve: Numerator ÷ Denominator = 12 <span>÷ 4 = 3.
_______________________________________
The answer is: [B]: 3.

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a radius of 12 feet and

Karolina [17]

Answer:

Step-by-step explanation:

Container A = 75.36 x 17 = 1,281.12

Container B = 62.8 x 18 = 1,130.4

1,281.12 - 1,130.4 = 150.72 is left in container A.

So, 1,130.4 was taken out of it.

1,281.12 divided by 1,130.4 = 1.13

move the decimal over two to the right. Or times it by 100.

Step-by-step explanation:

18% compounded monthly

charges 18% compounded semi-annually.

#1 is worse than #2 because...

Since the nominal rates are the same, the card with the more frequent compounding so it would have the higher effective rat.

Let's compare them!:

(1 + .18/12)^12 = 1.19562 ---> effective rate is 19.562 per annum

(1+.18/2)² = 1.1881

1.1881 has the effective rate of 18.88% per annum

(1 + /17/4)^4 = 1.18114.. --> effective rate is 18.114% per annum

18% monthly is .18 over 12 each month = 0.015/month

so every month multiply by 1.015

total cost = $607.99 * 1.01^number of months

18% semi annual = .18/2 every six months = .09 /half year

so every half year (6 months) multiply by 1.09

total cost = $607.99 * 1.09^ (number of months/6)

17% quarterly = .17/4 every 3 months = .0425 /quarter year

so every quarter year (3 months) multiply by 1.0425

total cost = $607.99 * 1.025^(number of months/3)

HOPE THIS HELPS YOU HAVE A GREAT GREAT GREAT FANTASTIC FRIDAY!

Find the results combining these functions.

vodomira [7]

Given $f(x) = x^2 + 6x + 9, g(x) = x^2 - 9$ :

$(f+g)(x) = (x^2 + 6x+9)+(x^2-9) =2x^2+6x=2x(x+3)$ , which is the second expression

$(f-g)(x) = (x^2 + 6x+9)-(x^2-9) =6x+18=6(x+3)$ , which is the first second expression

$(fxg)(x) = (x^2+6x+9)(x^2-9) = (x^4-9x^2)+(6x^3-54x)+(9x^2-81)=x^4+6x^3-54x-81$ , which is the fourth expression

$(f/g)(x) = (x^2+6x+9)/(x^2-9) = \frac{(x+3)^2}{(x+3)(x-3)} = \frac{x+3}{x-3}$ , which is the third expression

Which figure could be the result of dilating the trapezoid with a scale factor between 0 and 1? On a coordinate plane, a trapezo

Lena [83]

Answer:

On a coordinate plane, a trapezoid has points (0, 0), (0.5, 2), (1, 2), (1.5, 0).

Step-by-step explanation:

If a trapezoid is dilated with a scale factor between 0 and 1, the resulting trapezoid will look smaller than the original trapezoid.

Since the figure is missing, we can examine the coordinates.

By analyzing the coordinates critically, the correct choice is :

On a coordinate plane, a trapezoid has points (0, 0), (0.5, 2), (1, 2), (1.5, 0).

Because when we compare to the original figure with coordinates:

(0, 0), (1, 4), (2, 4), (3, 0), we can see that, the coordinates of the original figure were multiplied by $\frac{`1}{2}$ .

The scale factor is $k=\frac{`1}{2}$ and this is between 0 and 1
