Answer:

x=-8.5.

Step-by-step explanation:

First, write an equation. Twice x (2x) plus 7 (+7) is the same as (=) negative ten (-10), or 2x+7=-10. To solve, first subtract 7 from both sides to get 2x=-17. Then, divide both sides by 2 (x=-8.5).

A cylindrical plastic pipe’s length is 12 cm and it’s radius is 2.5 cm. To the nearest tenth, what is the volume of the pipe?

NemiM [27]

Answer:

V = 235.6 cm³

Step-by-step explanation:

the formula for the volume of a cylinder of radius r and length h is

V = πr²h.

Here, r = 2.5 cm and h = 12 cm, so the volume is:

V = π(2.5 cm)²(12 cm) = 75π cm³

To the nearest tenth, this volume would be V = 235.6 cm³

How to evaluate the expression

jasenka [17]

Answer:

Step-by-step explanation:

$4^{5}$ can be expressed as $2^{(2)(5)}$ = $2^{10}$

Similarly $4^{8}$ can be expressed as $2^{(2)(8)}$ = $2^{16}$

Numerator becomes:

$2^{10}$ · $-2^{9}$ = $-2^{19}$

Denominator becomes:

$2^{16}$ · $-2^{3}$ = $-2^{19}$

Since numerator = Denominator,

Answer = 1

Edit reason: typo
