Answer:

$0.65

Step-by-step explanation:

x=cost of washcloth

x+1.20=cost of towel

Now,

x+x+1.20=2.50

2x=1.30

x=0.65

Determine if x-6 is a zero and find the quotiant and the remainder

Genrish500 [490]

Answer:

○ A. No, x = -6 is not a zero of the polynomial.

The quotient is x - 29, and the remainder is 234.

Step-by-step explanation:

[x - 3][x - 20] >> Factored Form

Obviously, this is not a zero. Now, to get the remainder, we have to plug in the vertical line of <em>x = -6</em> into its conjugate, meaning an expression with opposite signs, which is <em>x + 6</em>. This is the expression we divide the dividend by, so you will have this:

\frac{{x}^{2} - 23x - 60}{x + 6}

Since the divisor is in the form of <em>x - c</em>, using Synthetic Division, we get this:

x - 29 + \frac{234}{x + 6}

You see? You have <em>x - 29</em> in the quotient, and you have 234 as the numerator remainder.

I am joyous to assist you anytime.

f(x)= x^2 - 2x find the following: f(6)=[ ], f(-3)=[ ], and finally, find f(-4)=[ ] thank you.

GREYUIT [131]

Answer:

f(6) =6^2 - 2(6)

f(6) = 36 - 12

f(6) = 24

f(-3) = (-3)^2 - 2(-3)

f(-3) = 9+6

f(-3) = 15

f(-4) = (-4)^2 - 2(-4)

f(-4) = 16 + 8

f(-4) = 24

Un pueblo tenía 13.578 habitantes en 1970. En 1988 la población se incrementó 1,5 veces con respecto a 1970 y en 2001 se increme

igor_vitrenko [27]

Answer:

En 2001 el pueblo poseía 45.826 habitantes.

Step-by-step explanation:

Un pueblo tenía 13.578 habitantes en 1970. En 1988 la población se incrementó 1,5 veces con respecto a 1970. Para calcular entonces la población en 1988 debes realizar el siguiente cálculo:

13.578*1,5= 20.367

Por lo que en 1988 el pueblo poseía 20.367 habitantes.

En 2001 se incrementó la población 2,25 veces en relación a 1988. Para calcular entonces la población en 2001 debes realizar el siguiente cálculo:

20.367* 2,25= 45.825,75≅ 45.826

Por lo que <u><em>en 2001 el pueblo poseía 45.826 habitantes.</em></u>

a long board 4.7 thick is cut into three pieces of equal length these three pieces are then stacked the stack is cut in three eq

nalin [4]

The number of pieces per stack after 3 cuts represented by a power expression can be written as $3^{3}$

The number of equal pieces per cut = 3

The number of cuts made = 3

<u>Using a power </u><u>expression</u><u> </u><u>:</u>

The number of of equal pieces per cut is raised to a power which represents the number of cuts made

Thus we have $number\: of \:equal\: pieces^{number\: of \:cuts}$

After 1 cut ; $3^{1} = 3$
After 2 cuts ; $3^{2} = 3\times3 = 9$
After 3 cuts ; $3^{3} = 3\times3\times3 = 27$

Therefore, the Number of pieces present in stack after 3 cuts is $3^{3}$

Exclain why 0.32 with a line above it is greater than 0.32

ella [17]

"0.32 with a line above it" could refer to two possible numbers, either $0.\overline{32}=0.323232\ldots$ or $0.3\overline2=0.3222\ldots$ .

In either case, 0.32 will be the smaller of the two numbers simply because it terminates with two digits after the decimal point, while the others keep going, basically adding a small positive number to 0.32.
