Make 10 equations for 50,000
Kruka [31]

Answer:

1. 50 * 1,000 = 50,000

2. 49,001 + 999 = 50,000

3. 5 * 10,000 = 50,000

4. 100,000/2 = 50,000

5. 20,000 + 30,000 = 50,000

6. 50,000/1 = 50,000

7. 90,000 - 40,000 = 50,000

8. 10 + 49,990 = 50,000

9. 5,000 * 10 = 50,000

10. 1,000,000/20 = 50,000

Giovanni purchased 25tickets to an airshow. the cost of an adult's ticket is $14 and the child's ticket is $8. if the total cost
Masteriza [31]

Giovanni purchased 20 adult tickets and 5 child's tickets.

Step-by-step explanation:

Let,

x = Adult tickets

y = Child's tickets

According to given statement;

x+y=25 Eqn 1

One adult ticket costs $14 and one child ticket costs $8, therefore,

14x+8y=320 Eqn 2

Multiplying\ Eqn\ 1\ by\ 8\\8(x+y=25)\\8x+8y=200\ Eqn\ 3\\Subtracting\ Eqn\ 3\ from\ Eqn\ 2\\(14x+8y)-(8x+8y)=320-200\\14x+8y-8x-8y=120\\6x=120\\Dividing\ both\ sides\ by\ 6\\\frac{6x}{6}=\frac{120}{6}\\x=20

Putting value of x in Eqn 1;

20+y=25\\y=25-20\\y=5

Giovanni purchased 20 adult tickets and 5 child's tickets.

A line has the points (3,7) (4,9) (5,11) (6,13). If the slope is divided by 2, what is the new slope?
lorasvet [3.4K]

Answer:

The new slope is 1

Step-by-step explanation:

The slope of any two points can be found by:

slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Finding slope of (3,7) (4,9)

slope=\frac{9-7}{4-3}\\slope=\frac{2}{1}\\slope=2

Finding slope of (4,9) (5,11)

slope=\frac{11-9}{5-4}\\slope=\frac{2}{1}\\slope=2

So, the slope of the line is 2

Now if slope is divided by 2, new slope will be:

slope = \frac{2}{2}\\slope=1

So, The new slope is 1

Jennifer needs to use a ladder to clean a second floor window on a building. If the window is 13 ft above the ground and the bas
BigorU [14]

By using the Pythagoras theorem, the length of the ladder will be 13.6 feet.

<h3>What is a Pythagoras theorem?</h3>

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

Jennifer needs to use a ladder to clean a second-floor window on a building.

If the window is 13 ft above the ground and the base of the ladder is 4 ft from the building.

Then the length of the ladder will be

H² = 13² + 4²

H² = 169 + 16

H² = 185

H = 13.6 ft

More about the Pythagoras theorem link is given below.
