A wooden flagpole is 25 foot tall. In a storm, the flagpole is broken and its top touches the ground 5 foot from the base. Find
Mumz [18]

Answer: x = 12 ft

Step-by-step explanation:

let the erect part of the pole be x

the slanted part of the pole will be 25-x

the ground distance = 5

they form a right triangle

apply Pythagoras theorem

5^2+x^2=(25-x)^2

25+x^2=x^2 - 50x + 625

50x=625-25

50x=600

x=600/50

x=12 feet

2 cups of low fat yogurt and and 3 bananas contain 650 calories, 4 cups of low-fat yogurt and 2 bananas contain 900 calories. Ho
LenKa [72]

Answer:

A cup of yogurt has 175 calories.

Step-by-step explanation:

We can solve for the amount of calories in one cup of yogurt and in one banana by setting up and solving a system of equations.  Given the information in the problem '2 cups of yogurt and 3 bananas is 650 calories' and '4 cups of yogurt and 2 bananas is 900 calories' we can set up two equations:

2y + 3b = 650 and 4y + 2b = 900, where 'y' is the cups of yogurt and 'b' is the number of bananas.  

Using elimination, we can multiply the first equation by a factor of '-2' and then add the equations together to solve for the remaining variable:

-2(2y + 3b = 650) = -4y - 6b = -1300

-4y - 6b = -1300

<u>+ 4y + 2b = 900</u>

-4b = -400, or b = 100, so each banana has 100 calories, if each banana has 100 calories: 4y + 2(100) = 900 or 4y = 700 or y = 175.  So, each cup of yogurt has 175 calories.
