Answer:

she would need 2 bags because it is 18 but covers 10 square feet

Step-by-step explanation:

Width = 1 yard = 3 feet

Length = 6 feet

Square feet(area) of the floor = 6ft × 3ft = 18sqft

1 bag = 10sqft

x bag = 18 sqft

x bags = (18 × 1)/10

= 1.8 bags

2 bags

Answer:

The equation represents: A relation and a function

Step-by-step explanation:

A function is said to be a relation; however, the relation does not have to function. For a relation to result in a function, then every input gives an important output. Thus; the given information x² + y - 15 = 0 can be re-written as:

y = - x² + 15

Similarly, the equation typically illustrates a relation as well. Consequently, suppose we replace any x-value for x, then the one possible output will be for y. Hence, that is also a function.

Answer: The answer is b

Step-by-step explanation: just multiply 3x5=15x2=30

Answer: See in the explanation

Step-by-step explanation:

The domain is all of the X values in a set.  

The range is all of the Y values in a set.

You can tell if a set of coordinate pairs is a function if each x value corresponds to 1 Y value. For example, lets say we have an x value of 3. This X value can only correspond to ONE y value. So if the x value 3 corresponded to , e.g, 4, or 7 as y values, it would not be a function because 1 x value has to have only 1 y value. 

a. {(0,9), (8, 1), (-1, 9), (9, 8), (1, -1)}

* This relation is a function, because there aren't many of the same x value numbers.

* The domain is {0, 8, -1, 9, 1}. Those are all of the X values

* The range is {9, 1, 9, 8, -1} (All of the Y values)

b. {(62, -3.1), (61, -3.1), (60, -3.1), (-3.1, -3.1)}

* This relation is a function, because even though all of the y values are the same , the x values are different.

* The domain is {62, 61, 60, -3.1}.

* The range is {-3.1, -3.1, -3.1, -3.1}

c. {(123,876), (-15, 2.6), (2.6, -15), (123, 1), (-87, -0.98)}

* This relation is a function, because all of the X values are different

* The domain is {123,876, -15, 2.6, 123, -87}

* The range is {0, 2.6, -15, 1, -0.98}

d. {(2.9, 0), (2.9, 1), (2.9, 2), (2.9, 3)}

* This relation is not a function. All of the x values are the same, and for this reason, they all have different y values.

* The domain is {2.9, 2.9, 2.9, 2.9}

* The range is {0, 1, 2, 3}

Answer:

55

Step-by-step explanation:

These angles are called complementary angles where the sum of the angles = 90°

So,

(4x + 7) + 35 = 90°

Subtract 35 on both sides

4x + 7 = 55

Subtract 7 on both sides

4x = 48

Divide 4 on both sides

x = 12

(Edit: 4(12) + 7 = 55, my bad I didn’t read the problem correctly and focused on solving for x)

Answer: ZYX=55 x=12

Step-by-step explanation: that square in the corner means the angle is 90 degrees so 90-35=55. XYZ=55 (now im guessing that wasn’t the whole question since there was an x) so then 55-7 (since you would do adding last, backwards you do subtraction first) =48. 48 divided by 4=12 x=12

Step-by-step explanation:

Let's first figure out how far each of them traveled before they meet. Let TIME be the time in hours since they began traveling.

Domingo traveled a distance of 55 * TIME miles

Bethany traveled a distance of 60 * TIME miles

We know that their total distance is 575 miles. So we can write the equation:

55 * TIME + 60 * TIME = 575

Simplifying this equation, we get:

115 * TIME = 575

Dividing both sides by 115, we get:

TIME = 5

So they meet 5 hours after they began traveling. Since Domingo left at 1 p.m., he will meet Bethany at 6 p.m.

They will pass each other at 6 pm.

Given,

Domingo and Bethany drove along the same highway but in opposite direction.

Let's first figure out how far each of them traveled before they meet.

Let x be the time in hours since they began traveling.

Domingo traveled a distance of 55 * x miles

Bethany traveled a distance of 60 * x miles

We know that their total distance is 575 miles. So we can write the equation as,

55 * x + 60 * x = 575

Further simplifying this equation, we get:

115 * x = 575

x = 5

So they meet 5 hours after they began traveling.

Since Domingo left at 1 p.m., he will meet Bethany at 6 p.m.

Answer:20.7 units²

Step-by-step explanation: volume of a rectangular prism is L×W×H

therefore 82.8=L×W×the height which is 4 units so if u do 4×L×W you get 4LW which is the volume

(4LW=82.8) now divide 82.8 by 4LW to get the value of LW. The value of LW is an area of one of the bases because area is L×W which is basically LW

Answer: the perimeter of the garden is 38 units.

Step-by-step explanation:To find the perimeter of the garden, we need to add up the lengths of all four sides.

Starting with the bottom side, we can use the coordinates (-7, 2) and (4, 2). The distance formula tells us that the distance between these two points is:

d = √[(4 - (-7))^2 + (2 - 2)^2]

 = √[11^2 + 0^2]

 = √121

 = 11

So the bottom side has a length of 11.

Moving to the right side, we can use the coordinates (4, 2) and (4, 10). Again using the distance formula, we get:

d = √[(4 - 4)^2 + (10 - 2)^2]

 = √8^2

 = 8

So the right side has a length of 8.

For the top side, we can use the coordinates (4, 10) and (-7, 10):

d = √[(-7 - 4)^2 + (10 - 10)^2]

 = √11^2

 = 11

So the top side also has a length of 11.

Finally, for the left side, we can use the coordinates (-7, 10) and (-7, 2):

d = √[(-7 - (-7))^2 + (2 - 10)^2]

 = √8^2

 = 8

So the left side has a length of 8.

Adding all four side lengths together, we get:

Perimeter = 11 + 8 + 11 + 8

         = 38
