Answer:

13.5

Step-by-step explanation:

Using sine rule

Tan25 = AC/AB = AC/29

makvit [3.9K]

Answer:

The new store will have a profit of $5400 after its fifth month.

(R-C)(x) = (x²+5x+14)-(x²-4x+5) = x²-x²+5x--4x+14-5 = 5x+4x+14-5=9x+9

(Use 5 for x)

(R-C)(5) = 9(5) + 9 = 45+9 = 54

As a salesperson, you are paid $100 per week plus $3 per sale. This week you want your pay to be at least $160. Write an inequal

Rom4ik [11]

Answer:

100 +3s≥ 160

You must sell as least 20 items

Step-by-step explanation:

You make 100 plus 3 dollars per sale

100 +3s

It must be at least 160

100 +3s≥ 160

Now we need to solve to see how many sales

100 +3s≥ 160

Subtract 100 from each side

100-100 +3s≥ 160-100

3s≥ 60

Divide each side by 3

3s/3≥60/3

s≥20

You must sell as least 20 items

Substituting the equation y = 4x + 1 into the equation 2y = -x – 1 will produce the equation ________.

Zarrin [17]

Answer:

Step-by-step explanation:

Substituting y = 4x+1 into 2y = -x-1 gives the equation

2(4x+1) = -x-1

Solve the equation:

8x+2 = -x-1

9x = -3

x = -⅓

Answer:

D. 7.5 inches

Step-by-step explanation:

So, we can find the ratio of the big triangle to the small one by dividing the values of the hypotenuse.

So, 18/6 = 3

Big:small = 3:1

So, using this we can make an equation to find AD.

Let's say ED=x.

AD is basically ED (x) + AE (5).

Since ED is part of the small triangle, and AD is part of the big one, we can use the 3:1 ratio from above.

So, $\frac{x+5}{x}$ =3.

Multiply both sides by x, getting x+5 = 3x.

Subtract the x: -x -x

And you get 5=2x, giving you 2.5 = x.

However, we're not done yet, as 2.5 is the value of ED, but we need AD.

Remember, AD is = ED + AE.

So, AD = 2.5 + 5.

Finally, AD = 7.5
