pls help 209572.999129 round to the nearest cent

Answers

Answer:

$209,573.00

Step-by-step explanation:

when rounding to a place, you only need to look at the numbers one place beyond the place you are rounding to. For example, if you want to round 0.878 to the nearest tenth, you only need to look at 0.87, since both 0.87 and 0.878 round to 0.9. In this case, you are rounding to the nearest hundredth because one cent represents one hundredth of a dollar. You only need to look at 209572.999. Since the last digit is 9, which is greater than 5, you round up to 209573.00.

Johanna used tiles to build a rectangular array with an area of 54 W. All the possible dimensions of the array

Answers

Answer:

4

Step-by-step explanation:

To Obtian the possible dimensions of the array :

List out the factirs of 54 and use a pair of each in multiplication to obtain 54 ; Theb number of multiplication pairs obtained is the number of possible dimensions of the array :

Factors of 54 : 1, 2, 3, 6, 9, 18, 27, 54

Muliplication pairs :

(6 * 9) = 54

(18 * 3) = 54

(27 * 2) = 54

(54 * 1) = 54

Hence, there are 4 possible dimensions of the array

A) 1 year
B) 8 years
C) 87 years
D) 90 years

Answers

Answer:

C.) 87 years

Step-by-step explanation:

I've taken the test! Hope this helps! ;)

The number of years for her to have at least $100,000 if interest is compounded continuously is 90

How to determine the number of years?

The given parameters are:

Amount, A = 100,000

Principal, P = 100

Rate, r = 8%

Amount is calculated using:

A = P * (1 + r)^t

So, we have:

100000 = 100 * (1 + 8%)^t

Divide by 100

1000 = (1 + 8%)^t

Evaluate the sum

1000 = 1.08^t

Take the logarithm of both sides

log(1000) = log(1.08)^t

Apply the law of logarithm

log(1000) = tlog(1.08)

Solve for t

t = log(1000)/log(1.08)

Divide

t = 89.7

Approximate

t = 90

Hence, the number of years is 90

Step-by-step explanation:

The volume of the rectangular prism is 221.1 in³.

What is volume?

The volume of any object defined the capacity of it, how much it can hold something is called its volume.

Given is rectangular prism, we need to find the volume of the same,

So, we know that the volume of a rectangular prism is the product of its dimensions.

V = length × width × height.

[tex]V = 16\frac{3}{4} \times 4\frac{2}{5} \times 3[/tex]

[tex]V = \frac{67}{4} \times \frac{22}{5} \times 3[/tex]

V = 4422/20

V = 221.1

Hence, the volume of the rectangular prism is 221.1 in³.

Answers

Respuesta:

3x-y-1 = 0

Explicación paso a paso:

La forma estándar de ecuación de una línea se expresa como y = mx + b

M es la pendiente

b es la intersección con el eje y

Dada la coordenada P1 (2,5) y P2 (4,11)

Pendiente m = y2-y1 / x2-x1

m = 11-5 / 4-2

m = 6/2

m = 3

Sustituya m = 3 y (2,5) en y = mx + b

5 = 3 (2) + b

5 = 6 + b

b = 5-6

b = -1

Obtén la ecuación

y = 3x-1

Igualar a cero

y - 3x +1 = 0

Multiplicar por -1

3x-y-1 = 0

Esto da la ecuación requerida
