Answer:

13 over 22

Step-by-step explanation:

because you want to change the denominator to where they can match. So 22 is where 11 and 2 can match. then you want to multiply the amount you multiplied with the denominator so 1 over 11 would be 2 over 22. And 1 over 2 would be 11 over 22. and then you can add. 11 plus 2 is 13 and you can keep the denominator the same. Therefore, the answer would be 13 over 22

hope i helped.

Answer:

a. two column proof

Step-by-step explanation:

This is a two column proof, for 2 columns are given to you.

One column is the "Statements" column, which lists everything in mathematical terms.

The other column is the "Reasons" column, which lists everything by definition (either Theorem, Postulate, or Definition).

A zipline is constructed over a ravine as shown in the diagram at the right. What is the horizontal distance from the bottom of

Katyanochek1 [597]

Answer: X= 284.04

To solve for x, you must first find the missing angle in the left corner. I will name it "< Y" (Angle Y)

Sin50/250 = SinY/60

Set up your problem, then cross multiply.

60(Sin50)= 250(Sin Y)

60(Sin50)/250= Sin Y

After cross multiplying, you should be left with this. You then cancel out 250 by dividing it on both sides to get Sin Y by itself.

Sin Y = 0.183

Y= Sin-1 x 0.183

This is what it solves out to.

Now you cancel out Sin on both sides, and it should look like the bottom problem.

Y= 10.5

This is now your answer to plug into the problem needed to solve for X.

Now because you have 2 out of 3 angles, you can solve for the missing angle that lays opposite to x. ( in SOHCAHTOA you need the OPPOSITE and the HYPOTENUSE. The Hypotenuse is originally give, but we had to do extra solving to find the Opposite's degree.)

Because degree's in a triangle add to 180, we will add 50 degrees + 10.5 degrees to get 60.5 degrees. Now subtract 60.5 from the full 180 degrees and we get 119.5 degrees as the missing number that lays opposite from X. Now we can solve for X.

(Sin 119.5)/x = (Sin 50)/250

Set up your final problem as so and cross multiply.

X(Sin 50) = 250(Sin 119.5)

X = 250(Sin119.5)/(Sin50)

After cross multiplying, the problem should look like the one at the top. Cancel out Sin 50 to get X by itself by dividing both sides by Sin 50, then solve for X.

What is the solution to 3 + 4e^x+1 = 11?

Alexandra [31]

What is the solution to 3 + 4e^x+1 = 11?

Solution:

$3+4e^{x+1}=11$

To solve for x, Let us subtract 3 from both sides

$3+4e^{x+1}-3=11-3$

$0+4e^{x+1}=8$

$4e^{x+1}=8$

Let us divide by 4 on both sides

$\frac{4e^{x+1}}{4} =\frac{8}{4}$

$\frac{1e^{x+1}}{1} =\frac{2}{1}$

$e^{x+1} =2$

Let us take ln on both sides

$ln (e^{x+1}) =ln(2)$

So, x+1=ln(2)

To solve for x, Let us subtract 1 from both sides

x+1-1=ln(2) -1

x+0=ln(2)-1

x= ln(2) -1

Answer: Option (A)

x=ln(2)-1

Need help on 8,9,10,11 and 12

GalinKa [24]

8) 12 is 30% of some number, which we'll call x. We can write the percent as a decimal and solve for x
$0.3x=12 \\ \\ x = 40$ .
The answer is 40.

9) 45% of 20 is $0.45(20)=9$ .

The answer is 9.

10) 18 is $(18/30 = 60)$ % of 30.

The answer is 60%.

11) 56 is 80% of some number x. We write
$0.8x=56 \\ \\ x = 70$ .

The answer is 70.

12) If the total cost on an item that costs $4.00 is $4.32, then the tax is 32¢. We want to find the percent of the total 4 that is .32. $\frac{0.32}{4} = 0.08=8$ %.

The answer is 8%.
