Answer:

x ≅ 0.477.

Step-by-step explanation:

You probably meant:

$10^x = 3.$

If that is the case, then let's solve it:

$10^x = 3\\\\log\,10^x=log\,3\\\\x = log\,3\\\\x = (approx.)\,\,0.477.$

Answer:

$15x+60\leq 100$

Step-by-step explanation:

Let

x -----> the number of hours that the painter works

we know that

The inequality that represented this situation is equal to

$15x+60\leq 100$

solve for x

Subtract 60 both sides

$15x\leq 100-60$

$15x\leq 40$

Divide by 15 both sides

$x\leq 40/15$

$x\leq 2.67\ hours$

The maximum number of hours is 2

Adam, Brian, and Christine order two small pizzas. Adam eats three quarters of a pizza, Brian eats one third of a pizza, and Chr

<h3>Answer: 11/12</h3>

============================================================

Explanation:

3/4 = 9/12 after multiplying top and bottom by 3

1/3 = 4/12 after multiplying top and bottom by 4

When combining the fractions 3/4 and 1/3, we get,

3/4 + 1/3 = 9/12 + 4/12 = (9+4)/12 = 13/12

Let's convert that result into a mixed number

13/12 = (12+1)/12

13/12 = 12/12 + 1/12

13/12 = 1 + 1/12

13/12 = 1 & 1/12

Adam and Brian have collectively eaten 1 full pizza plus an additional 1/12 of the second pizza. This leaves 11/12 of the second pizza for Christine to eat. Notice how the fractions part 1/12 and 11/12 add to 12/12 = 1.

1/3 x +5 =5.5 what is the value of x ?

Leno4ka [110]

Answer:

x=11.5

Step-by-step explanation:

You want to isolate x. The first thing you have to do is get rid of that tricky fraction. To do this, you have to multiply the fraction by its denominator to cancel the denominator out and leaving you only with the numerator. You would also have to multiply 3 by 5.5 too. (Multiplying by the denominator only gets rid of the denominator and leaves the numerator alone. However, in your case, the numerator is one, so by getting rid of the denominator you get 1x. This can just be written as x.)

Equation would look like this:

x+5=16.5

You subtract 5 from both sides, and 16.5 minus 5 is 11.5

Equation would now look like this:

x=11.5

Where e is enclosed by the planes z = 0 and z = x + y + 9 and by the cylinders x2 + y2 = 4 and x2 + y2 = 16?

katrin [286]

Best to use cylindrical coordinates. The volume (assuming that's what you're supposed to find) of the region is given by the triple integral

$\displaystyle\iiint_E\mathrm dV=\int_{\theta=0}^{\theta=2\pi}\int_{r=2}^{r=4}\int_{z=0}^{z=r(\cos\theta+\sin\theta)+9}r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta$
$=\displaystyle\int_{\theta=0}^{\theta=2\pi}\int_{r=2}^{r=4}(r^2(\cos\theta+\sin\theta)+9r)\,\mathrm dr\,\mathrm d\theta$
$=108\pi$
