Answer:

C. √16,200 feet

Step-by-step explanation:

According to Pythagorean theorem

c^2 = a^2 + b^2

Home First and Third is formed a right triangle with 2 equal sides = 90 ft

c^2 = 90^2 + 90^2

c^2 = 8100 + 8100

c^2 = 16,200

c = √16,200

Answer

C. √16,200 feet

If a baker doubles recipe that call for 6-23 of flour how many cups of flour will be needed in all

Dennis_Churaev [7]

Unsure of what you mean by "6-23." There's no subtraction in this problem.

If you meant "6/23," then "doubling" that results in 12/23 cups. Still, that does not look right. Go back and ensure that you have copied down the original problem exactly.

HELP PLEASE Sam and George both worked hard over the summer. Together they earned a total of $525. George earned $75 more than S

ZanzabumX [31]

Answer: Sam = $225 George = $300

<u>Step-by-step explanation:</u>

NOTES:

Sam: s

George: g = s + 75

Together: s + g = 525

The two equations that can be created are "George" and Together"

The system is: $\left \{ {{\text{g = s + 75}} \atop {\text{s + g = 525}}} \right.$

see attached graph

The intersection of the two lines is at (225, 300). Since Sam represented the x-axis and Georege represented the y-axis, then Sam = $225 and George = $300.

BONUS:

This system can also be solved algebraically using the substitution method.

Replace "g" with "s + 75" into the second equation:

s + (s + 75) = 525

2s + 75 = 525

2s = 450

s = 225

Next, input the s-value into the George equation to solve for g:

g = s + 75 = (225) + 75 = 300

Find the equation of a line passing through (3, -5) that is parallel to 2x+6y=10

Zina [86]

Answer:

The equation of the line would be y = -1/3x - 4

Step-by-step explanation:

In order to find this, we first need to find the slope of the original line. We do this by solving for y.

2x + 6y = 10

6y = -2x + 10

y = -1/3x + 5/3

Now that we see the slope as -1/3, we know the new line will have the same slope thanks to the definition of parallel lines. So, we can use this slope and the point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - -5 = -1/3(x - 3)

y + 5 = -1/3x + 1

y = -1/3x - 4
