The area of one floor tile is 92.16 square inches.What is the area of a kitchen floor covered with 102 floor tiles?

Answers

Answer:

9400.32 square inches

Step-by-step explanation:

The area of one floor tiles is 92.16

The area of a kitchen floor covered with 102 floor tiles can be calculated as follows

= 102 × 92.16

= 9400.32 square inches

Hence the area is 9400.32 square inches

Diego was asked to plot these points: (−50,0) ( − 50 , 0 ) , (150,100) ( 150 , 100 ) , (200,−100) ( 200 , − 100 ) , (350,50) ( 350 , 50 ) , (−250,0) ( − 250 , 0 ) . What interval could he use for each axis?

Answers

Answer:

We have the points:

(-50, 0)

(150, 100)

(200, -100)

(350, 50)

(-250, 0)

First, we need to find the smallest and largest values of the x-component.

The smallest value is x = -250

The largest value is x = 350

Then the interval that we choose for the x-axis should include these two values (so we can plot the points)

Then we need to use, at least, the interval [-250, 350]  (A interval that is a little bit larger than that will be easier to read, but that is the minimum he needs to do the plot)

Now let's do the same with the values of the y-components.

The smallest value is y = - 100

The largest value is y = 100

Then the vertical interval should be [-100, 100] or a little bit larger, like in the horizontal case.

We also can see that the values of x and y seem to jump in multiples of 50, then each unit of the grid could represent 50 units, so it is easier to plot. (These are also called intervals, and also theses will depend on each individual axis, but in this case we could use the same for both of them, because it works well for both axis)

Use an interval of 50, because all the

coordinates involve points that are greater than 50 and multiples of 50.

do you see a pattern or possible shortcut to simplify more quickly?

Lily drives 90 miles in 2 hours. If she drives at the same rate, how far does lily travel in each of the following time intervals: 1 hour, 1/2 hour, and 3 hours? Please solve in at least two different ways. You could make a bar model, double number line, ratio table, or graph.

How far does she travel in 1/2 hour?

Answers

Answer:

22.5 miles 1/2 hour - 45 miles 1 hour - 67.5 miles 1.5 hours - 135 miles 3 hours

Step-by-step explanation:

If Lily travels 90mph in 2 hours she would travel 45mph each hour. So now just take 45 times 1, 1.5, and 3 to get your answers. So in half an hour she would travel 22.5 miles

Sinah bought some packs of gum. There were 8 sticks of gum in each pack. She gave 12 sticks of gum to manuela. This left sinah with 28 sticks of gum. Which equation can be used to represent this situation where g is the number of packs of gum that sinah bought?

Answers

Answer:

8g = 12 + 28

g = 5 packs

Step-by-step explanation:

Share of the sticks of gum

Manuela = 12 sticks

Sinah = 28 sticks

There are 8 sticks in each pack

g = number of packs of gum that sinah bought?

g × 8 sticks = 12 sticks + 28 sticks

8g = 40

Divide both sides by 8

g = 40 / 8

g = 5 packs

The weight of a giant panda is 10 times the weight of a red panda. The combined weight of the pandas is 220 pounds. What is the weight of each panda?

Answers

Answer:

The weight of a giant panda = x = 200 pounds

The weight of a red panda = y = 20 pounds

Step-by-step explanation:

Let

The weight of a giant panda = x

The weight of a red panda = y

The weight of a giant panda is 10 times the weight of a red panda.

x = 10y

The combined weight of the pandas is 220 pounds.

x + y = 220

We substitute 10 y for x

10y + y = 220

11y = 220

y = 220/11

y = 20 pounds

Solving for x

x = 10y

x = 10 × 20

x = 220 pounds

Hence:

The weight of each panda is:

The weight of a giant panda = x = 200 pounds

The weight of a red panda = y = 20 pounds
