Answer:

x=33

Step-by-step explanation:

8^(x+7) = 32^(x-9)

Rewriting 8 as 2^3 and 32 as 2^5

2^3 ^(x+7) = 2^5^(x-9)

We know that a^b^c = a^(b*c)

2^(3*(x+7)) = 2^(5*(x-9))

2^(3x+21) = 2^(5x-45)

We know that if the bases are the same, the exponents are the same

3x+21 = 5x-45

Subtract 3x from each side

3x-3x+21 = 5x-3x-45

21 = 2x-45

Add 45 to each side

21+45 = 2x-45+45

66= 2x

Divide by 2

66/2 = 2x/2

33=x

A ramp has a horizontal distance of 10 feet and a vertical rise of 3 feet. Find the length of the ramp. Round to the nearest ten

Tatiana [17]

Answer:

Step-by-step explanation:

Tye length of the ramp can be gotten using Pythagoras theorem.

Horizontal distance = 10ft.

Vertical distance = 3ft

Length of the ramp² = 10²+3²

Length of the ramp² = 100+9

Length of the ramp² = 109

L² = 109

L =√109

L = 10.44ft

Hence the length of the ramp is 10.4ft to the nearest tenth

A waitress works 1.75 hours less in the afternoon than in the evening. If she works 5 1/8 hours in the afternoon, how many hours

Marianna [84]

Answer:

She worked $6\frac{7}{8}$ hours in evening.

Step-by-step explanation:

Let x be the hours she worked in evening,

Since, she works 1.75 hours less in the afternoon than in the evening.

So, the number of hours she worked in afternoon = x - 1.75,

According to the question,

$x-1.75 = 5\frac{1}{8}$

$x= \frac{41}{8}+1.75$ ( By adding 1.75 on both sides and change mixed fraction into simple fraction in right side )

$x=\frac{41}{8}+\frac{175}{100}$

$=\frac{1025+350}{200}$

$=\frac{1375}{200}$

$=\frac{55}{8}$

$=6\frac{7}{8}$

Hence, she worked $6\frac{7}{8}$ hours in evening.

Find the difference of 1/2 - 3/11

TEA [102]

1/2 - 3/11

Set both denominators (bottom numbers) to 22, so multiply the numerator of 1/2 by 11, and multiply the numerator of 3/11 by 2.

1/2 is now 11/22

3/11 is now 6/22

So, our new question is now : 11/22 - 6/22

Because the denominators are the same, all you have to do is simplify the top numbers.

So, 11-6 = 5

Therefore, your answer is 5/22
