Answer:

Mr. John will need not less than [tex]22\frac{1}{4}[/tex] feet of rope for the camping trip

Step-by-step explanation:

To get the total length of rope Mr John needs for the camping trip, we can simply add up the length of rope he needs to tie the logs to the length of rope he needs for the clothesline.

Length of rope he needs to tie the logs = [tex]12\frac{1}{2}[/tex]

Length of rope he needs for the clothesline = [tex]9 \frac{3}{4}[/tex]

to sum this up, we, first of all, add up the whole numbers

12 + 9 = 21.

We then keep this aside then add up the fractions

[tex]\frac{1}{2} +\frac{3}{4} =\frac{2 +3}{4} = 5/4 = 1\frac{1}{4}[/tex]

We then add this to our whole numbers

[tex]21 + 1\frac{1}{4} =22 \frac{1}{4}[/tex]

Mr. John will need not less than [tex]22\frac{1}{4}[/tex] feet of rope for the camping trip

Answer:

  2/3·fg

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

  (ab)^c = (a^c)(b^c)

  (a^b)^c) = a^(bc)

__

We assume your 'x' is a multiplication symbol, so you want to simplify ...

  [tex]3f^4g^3 \times\dfrac{ 8fg^4}{ (6f^2g^3)^2}\\\\=\dfrac{3\cdot8f^{4+1}g^{3+4}}{6^2f^{2\cdot2}g^{3\cdot2}}=\dfrac{24}{36}f^{5-4}g^{7-6}\\\\=\boxed{\dfrac{2}{3}fg}[/tex]

Answer:

z=70, y=102

Step-by-step explanation:

180-110 = 70

so, z=70

99+89+70 = 258

360-258 = 102

so, y=102

Answer:

35 degrees

Step-by-step explanation:

(180-x)= supplement

(90-x)=complement

(180-x)-2(90-x)=35

180-x-180+2x=35

x=35

Answer:

A: 4.4    B: 0.875

Step-by-step explanation:

22/5=4.4. We know this because 22/5 simplified is 4 2/5, which converted to a decimal is 4.4.

7/8=0.875. We know this because 7/8 converted to a decimal is 0.875.

Answer:

Step-by-step explanation:

From the question, we're told that the length of the garden is 3 feet longer than its width. Mathematically, we would have

l = w + 3, where

l = length of the garden

w = width of the garden

Again we're told that this same garden has a walkway of about 2 foot wide. Mathematically we would have that as

W(w) = 2, where

W(w) = width of the garden.

That's all the parameters given in the question

Answer:

7.4 % is percent error

Step-by-step explanation:

https://brainly.com/question/21689164

The percent of error is 7.4%. The correct option is B.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Estimated value: 231

Actual value: 215

To find the percentage:

First, the value,

= 231 - 215

= 16

Now,

let n be the percentage.

So,

16 = n x 215/100

n = 1600/215

n = 7.4%

Therefore, 7.4% is the error.

Answer:

2 years = 1252.80 5 years =1332

Step-by-step explanation:

1,200 x 2.2% = 26.4

26.40 x 2 = 52.80

1200 + 52.80 = 1252.80

26.40 x 5 =132
