You are painting the walls and ceiling of a rectangular 20 x 30 ft room. The walls are 10 feet tall. You need two coats of paint

Mkey [24]

Answer:

$424

Step-by-step explanation:

Find area of all surfaces to be covered

20 x 30 = 600 ceiling

10 x 20 = 200 x 2 = 400 two walls

10 x 30 = 300 x = 600 other two walls

Assume no doors

total area is 1600 square feet

multiply by 2 because you are doing two coats

3200 total area to be covered

3200/400 = 8 gallons of paint x $53 = $424

(1.8x10^5)divided by(3x10^6) in standard form?

Softa [21]

Answer:

0.06

Step-by-step explanation:

Given data:

$1.8(10^{5})$ divided by 3× $10^{6}$

Now,

$\frac{(1.8)10^{5} }{3(10^{6}) } \\=0.6(10^{5-6} )\\=0.6(10^{-1} )\\=0.06$

Answer will be 0.06

Determine the value of x to the nearest thousandth in the equation 8(2)^x+3=48

solong [7]

You probably mean either

$8\cdot2^x + 3 = 48$

$8\cdot2^{x+3} = 48$

Write 8 = 2³, so that in the first interpretation,

$8\cdot2^x = 2^3 \cdot 2^x = 2^{x + 3}$

and in the second,

$8\cdot2^{x+3} = 2^3 \cdot 2^{x+3} = 2^{x + 6}$

Then in the first interpretation, we have

$2^{x + 3} + 3 = 48 \implies 2^{x + 3} = 45 \implies x + 3 = \log_2(45) \implies x = \log_2(45) - 3 \approx \boxed{2.492}$

Otherwise, the second interpretation gives

$2^{x + 6} = 48 \implies x + 6 = \log_2(48) \implies x = \log_2(48) - 6 \approx -0.415$

Slope is the picture.

Point-slope form is y-2=-5/6*(x+1)

The y=mx+b is y=-5/6x+7/6
