.05 mi per min. There are 120 min in 2 hours. 6*120=0.05

(60 miles / 2 hours)(1 hour / 60 minutes)
= 60(1) miles / 2(60) minutes
= 60 miles / 120 minutes
= 0.5 miles/minute

$8^{3x-10}=4^{6x-27}\\\\(2^3)^{3x-10}=(2^2)^{6x-27}\qquad\text{use}\ (a^n)^m=a^{nm}\\\\2^{3(3x-10)}=2^{2(6x-27)}\qquad\text{use distributive property}\\\\2^{(3)(3x)+(3)(-10)}=2^{(2)(6x)+(2)(-27)}\\\\2^{9x-30}=2^{12x-54}\iff9x-30=12x-54\qquad\text{add 30 to both sides}\\\\9x=12x-24\qquad\text{subtract 12x from both sides}\\\\-3x=-24\qquad\text{divide both sides by (-3)}\\\\\boxed{x=8}$

Tim and Tom are painters. Tim and Tom are painting a crate. Tom paints 10 sq ft per minute. They painted a particular crate in 1

slava [35]

Tom-------------- >10 sq ft per minute

Tim------------------- >3.5*10=35 sq ft per minute

Both painters (10+35)=45 sq ft per minute

let's assume a cubic unit crate----------> V1=1*1*1=1 feet3

the total surface of the cube is S1=6*(1*1)=6 sq ft

if the volume of the cube increases twice

V2=2 feet3 ------------------- > 2=x*x*x------------- >x=2^(1/3)

And the S2=6*(2^(1/3)* 2^(1/3)=9.5244 sq ft

V2/V1=9.5244/6=1.5874

Therefore

If Tim and Tom----------------------- > take 1 day----------- > to paint a crate V1

For the crate V2------------- > take 1.5874 days

assuming an 8-hour work day

0.5874*8=4.70 hr-------------- > 4 h 42 min

The answer is 1 day 4h 42 min

The function P(x)equals0.35xnegative 76 models the relationship between the number of pretzels x that a certain vendor sells an

r-ruslan [8.4K]

Answer:

$P(X=700) =0.35*700 -76= 169$

Step-by-step explanation:

For this case we have the following profit function:

$P(X) = 0.35 X -76$

And we are interested on find the profit after selling 700 pretzels, so we just need to replace X=700 into the profit function like this:

$P(X=700) =0.35*700 -76= 169$

The profit function is on the figure attached. We see that for 0<X<217 we have negative profits, and for X>217 we will have positive values for the profit. And also we can see that for X=700 we have a profit of approximately 169.
