Answer:

Below in bold.

Step-by-step explanation:

If I have interpreted the question correctly it is:

3*3*3*3 *x*x*x*x = 34

81 x^4 = 34

x^4 = 34/81

x = +/- (⁴√34) / 3 is the exact answer , or:

x = +/- 0.805 to nearest thousandth.

The circumference of a roll of party streamers is 9 inches. The circumference decreases by 2 inches after you use the streamers

leonid [27]

For that case the new circumference is:
C = 9 - 2
C = 7 inches
By definition, the circumference is:
C = 2 * pi * r
Where,
r: radio
Substituting values:
7 = 2 * pi * r
Clearing the radio:
r = 7 / (2 * pi)
Then, the diameter is:
d = 2 * r
Substituting:
d = 2 * (7 / (2 * pi))
d = 2.228169203
Round to the hundredth:
d = 2.23 inches
Answer:
The diameter of the roll after the decrease is:
d = 2.23 inches

Which expressions are equivalent to 5p+3p+(-9)5p+3p+(−9)5, p, plus, 3, p, plus, (, minus, 9, )? Choose all answers that apply:

Lemur [1.5K]

Answer:

Option B.

Step-by-step explanation:

The given expression is

$5p+3p+(-9)$

We need to find an expression which is equivalent to the given expression.

Combine like terms.

$(5p+3p)-9$

$8p-9$

The simplified form of given expression is 8p-9. So, option A is incorrect.

In option B, the given expression

$3(p+(-3))+5p$

$3(p-3)+5p$

Using distributive property, we get

$3p-9+5p$

Combined liker terms.

$(5p+3p)-9$

$8p-9$

It is same as the simplified form of given expression.

Therefore, the expression 3(p+(-3))+5p is equivalent to the given expression and correct option is B.

Use the formula to evaluate the series 1/4 + 1/9 + 1/27 + 1/81.

Dmitriy789 [7]

Is the first term supposed to be 1/4, or did you actually mean 1/3?

I'll assume the latter. Write

$S=\dfrac13+\dfrac19+\dfrac1{27}+\dfrac1{81}$
$S=\dfrac13+\dfrac1{3^2}+\dfrac1{3^3}+\dfrac1{3^4}$
$\dfrac13S=\dfrac1{3^2}+\dfrac1{3^3}+\dfrac1{3^4}+\dfrac1{3^5}$
$\implies S-\dfrac13S=\dfrac13-\dfrac1{3^5}$
$\dfrac23S=\dfrac13\left(1-\dfrac1{3^4}\right)$
$S=\dfrac12\left(1-\dfrac1{81}\right)$
$S=\dfrac{40}{81}$
