Answer:

  1/18

Step-by-step explanation:

18 is a suitable denominator for both fractions:

  5/6 = 15/18

  7/9 = 14/18

Then the difference is ...

  5/6 -7/9 = 15/18 -14/18 = (15 -14)/18 = 1/18

There are 3 times as many dogs as cats.
If the total number of dogs and cats is 16, how many dogs are there?

Answers

Answer:

there are 12 dogs.

Step-by-step explanation:

d= dogs              now plug in the 4 into your equation.

c= cats                  d=3(4)

d+c=16                   d=12

3c+c=16

4c=16                        SO THEREFORE THERE ARE 12 DOGS :)

c=4

The enrollment at a university increased from 16,000 students to 20,000 students over a period of 5
years. What is the percent increase in enrollment?
difference
net/

Answers

Answer:

25%

Step-by-step explanation:

Initial no of students = 16,000

Final no of students = 20,000

We need to find the percent increase in enrollment.

The increase in no of students = 20,000 - 16,000

= 4000

Percentage = (increase/initial no of students) × 100

[tex]\%=\dfrac{4000}{16000}\times 100\\\\=25\%[/tex]

Hence, the percent increase is 25%.

The base of a 15 foot ladder is 9 feet from a building. The top of the leaning ladder reaches and makes contact with the building’s roof. On the corner of the building, a 6 foot flagpole is erected on the roof. What is the height from the base of the building to the top of the flagpole? Please show your work.

Answers

9514 1404 393

Answer:

  18 feet

Step-by-step explanation:

The ladder length represents the hypotenuse of a right triangle with a base of 9 and an unknown height (h). We can find that height by using the Pythagorean theorem.

  9² +h² = 15²

  h² = 225 -81 = 144

  h = √144 = 12

So, the ladder extends 12 feet up the side of the building. That is the height of the roof. The top of the flagpole is 6 feet above that, so the top of the flagpole is ...

  12 ft + 6 ft = 18 ft

above the ground.

The height to the top of the flagpole is 18 feet.

The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.

Step-by-step explanation:

According to the graph, the line crosses the y-axis at y = 4. Therefore, our y-intercept is 4. Writing it in coordinate point would be (0, 4), as definition of the y-int.

    It's the third option because if you put a piece of paper in the corner its a lil more than 90 degrees, so it wouldn't be B (there's a little more white space left). And it obviously wouldn't be A because that's self explanatory, lol.

    And you can't make a perfect square in the inside of the angle so that's another way to tell.

Read the passage. First identify the text structure used in the passage, and then explain how this structure helps develop the writer's central idea. Use evidence from the text in your response.The rise in popularity of farmers' markets has caused many people to rethink their use of regular grocery stores. Both have their advantages and disadvantages. Farmers' markets have fresh and local produce, and often you get a chance to meet the people who grow your food. This isn't the case with grocery stores, where you'll never get to meet the farmers. Grocery stores are starting to have more local products, though, and they have a better variety of goods. Another thing to consider is the setting itself. Farmers' markets are usually in more pleasant, open-air locations where there's often live music playing. Grocery stores, on the other hand, can be busy and uncomfortable if you don't like shopping. The pleasant atmosphere comes at a price, though, as your bill at a farmers' market is likely to be 25 percent more than at a grocery store. All in all, the freshness and quality of food is worth a little more money. Farmers' markets are the way to go. Thanks!!
