Answer:

x = 3.58

Step-by-step explanation:

$e^{4x - 5}$ - 7 = 11243
$e^{4x - 5}$ = 11250
ln $e^{4x - 5}$ = ln 11250
4x - 5 = ln 11250
4x - 5 = 9.33 (rounded)
4x = 14.33
x = 14.33 / 4
x = 3.58 (rounded)

Need help with this please

tester [92]

To find the area of the shaded region, we must first find the percentage that is shaded.

We understand that 140 degrees out of 360 degrees are unshaded, thus there are 220 degrees shaded.

Thus the percentage is equal to $\frac{220}{360}$

Area = $\frac{220}{360} *\pi* 18^{2} = 198\pi$ square yards

Hope that helps!

Answer:

300

Step-by-step explanation:

To find the number of pamphlets we use the following:

$NumberOfPamplets=\frac{TotalBudget}{CostPerPamphlet}$

we divide the total budget by the cost per pamphlet and then we will know how many of them he can make.

the total budget is:

$TotalBudget=3,000$

and the cost per pamphlet:

$CostPerPamphlet=10$

so we make the division:

$NumberOfPamphlets=\frac{3,000}{10}\\ NumberOfPamphlets=300$

The senator can make 300 pamphlets with the budget that he has.

Answer:

x=20

Step-by-step explanation:

The Pythagorean theorem is $a^2+b^2=c^2$ , where a and b are the legs (the smaller sides) and c is the hypotenuse. So, plugin 12 and 16 for a and b, then solve. This looks like $12^2+16^2=c^2$ . Next, simplify the equation, $12^2$ =144 and $16^2$ =256; then add 144+256. The new equation is 400= $c^2$ . The final step is to take the square root of both sides. Since $\sqrt{400}$ =20, x (the hypotenuse) must equal 20.
