Answer:

4' - 9.64

Step-by-step explanation:

Total rise = 2' - 7"

Total run = 3' - 9"

Converting to inches :

1' = 12" ; 1 feet = 12 inches

2' = 2 * 12 = 24"

3' = 3 * 12 = 36"

Total rise = 24" + 7" = 31"

Total run = 36" + 9" = 45"

Length of stringer = hypotenus

Hypotenus = √(total rise² + total run²)

Hypotenus = √(31² + 45²)

Hypotenus = 54.644304"

= 4' - 9.64"

HELP ASAP What is the solution to the system of equations? y = x + 3 y = -x-1

ASHA 777 [7]

Answer:

(A) Is right

Step-by-step explanation:

$y = x + 3 \\ y = - x - 1 \\ substitute \: y = - x - 1 \: in \: above \: eq \\ weget \\ - x - 1 = x + 3 \\ 2x = - 4\\ x = - 2 \\ \\$

put X= -2. in y = X+3

to get y 's value

Y = -2+3

= 1

therefore, your solution is ( -2,1)

The larger of two numbers is five more than the smaller number. If the sum of the numbers is 59, find the numbers

Andrews [41]

Answer:

27 and 32.

Step-by-step explanation:

Let the two numbers be A and B.

The larger number (let's use B) is 5 more than the smaller one (A). In other words:

$B=5+A$

Their sum is 59. So:

$A+B=59$

This is a system of equations. Solve by substituting the first equation into the second. Thus:

$A+(5+A)=59$

Combine like terms:

$2A+5=59$

Subtract 5 from both sides:

$2A=54$

Divide both sides by 2:

$A=27$

So, the smaller number is 27.

This means that the bigger number is 27+5=32.

So, the two numbers are 27 and 32.

And we're done!

What is equivalent to 1 and 5/6?? and what is 3 and 1/6 equivalent to?

ollegr [7]

Answer: 1.833 and 3.167

Step-by-step explanation:

1 and 5/6 is demonstrated with this equation:

$1 + \frac{5}{6} , \\\\\frac{6}{6} + \frac{5}{6} = \frac{11}{6} = 1.833\\$

3 and 1/6 is demonstrated with this equation:

$3 + \frac{1}{6}, \\\\\frac{18}{6} + \frac{1}{6} = \frac{19}{6} = 3.167$

Answer:

B. 56.52

Step-by-step explanation:

C = 2πr

C = circumference
r = radius of the circle
the constant pi = 3.14

Therefore,

56.52 = 2(3.14)(9)
