F = 4

if f(x)=11, you must always try and get x alone, so f = (11+5)/4, and this simplifies to 4.

alekssr [168]

Answer:

Step-by-step explanation:

so you are saying do:

$4^{2} /4^{6}$ which is 16 /4096

16/4096=0.00390625

<u>another way you can do this is</u>

$4^{2} /4^{6}$

just subtract the powers

2-6=-4

A bus trip takes 1.5 hours. By plane, the same trip takes 30 minutes. How

DENIUS [597]

Answer:

2 times faster

Step-by-step explanation:

because the plane takes one hour less than the bus and 60 min equal a hour and 30 plus 30 equal 60 which is a hour so then it would be 2 times as faster because it is 30 twice to equal the 60

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

Find the percentage of vacationers from<br> question 10 who spent between $1500<br> and $2000.

mars1129 [50]

Answer:

The percentage change of vacationers is 33.3 %

Step-by-step explanation:

Given as :

The old value of the vacationers = $ 1500

The new value of the vacationers = $ 2000

Let the percentage variation = x %

Or, x % increase = $\dfrac{\tyextrm new value - \textrm old value}{\textrm old value}$ × 100

Or, x % increase = $\dfrac{\tyextrm $ 2000 - \textrm $ 1500}{\textrm $ 1500}$ × 100

Or, x % increase = $\frac{500}{1500}$ × 100

Or, x % increase = $\frac{1}{3}$ × 100

Or, x % increase = $\frac{100}{3}$

∴ x = 33.3 %

So, The percentage increase change is 33.3 %

Hence The percentage change of vacationers is 33.3 % Answer
