Answer:

11

Step-by-step explanation:

Whole numbers are all those numbers that are zero or greater then zero, so:

{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, ......}

The list of the pairs is the following:

(0, 10)

(1, 9)

(2, 8)

(3, 7)

(4, 6)

(5, 5)

(6, 4)

(7, 3)

(8, 2)

(9, 1)

(10, 0)

Two pairs with the same numbers, but in different position are not the same thing. They are two different pairs.

For example, (2, 8) and (8, 2) are different. You can imagine them as points on a Cartesian coordinate system to understand why they are different. They are two different points.

What is the answer to y=6x−8 y=−3x+10 as an ordered pair
kompoz [17]

Answer:

(2, 4)

Step-by-step explanation:

To find the solution, set the equations equal to each other, then solve for x:

6x - 8 = -3x + 10

9x - 8 = 10

9x = 18

x = 2

Now, find the y value by plugging in 2 as x into one of the equations, and solve for y:

y = 6x - 8

y = 6(2) - 8

y = 12 - 8

y = 4

So, the solution as an ordered pair is (2, 4)

What is the value of x?<br><br> x = ___
Shalnov [3]

Answer:

x = 24

Step-by-step explanation:

The triangle is split into two similar triangles. They have the same shape but not the same size. To solve, write a proportion.

\frac{56}{44.8}=\frac{35}{x+4}

Cross multiply to solve for x.

56(x+4) = 44.8(35)

56x + 224 = 1,568

56x = 1,344

x= 24

A water trough is 7 m long and has a cross-section in the shape of an isosceles trapezoid that is 30 cm wide at the bottom, 70 c
valentina_108 [34]

Answer:

The degree of fastness by which the water is rising is 210 seconds

Step-by-step explanation:

The volume of the trough when the water depth is 20 cm is first calculated

Volume of the trough (Trapezoidal Prism) = LH (A + B) × 0.5

Where L is the length of the trough, H is the height of the trough and A and B are parallel width of the top and bottom of the trough

Volume of the trough = 7 × 0.2 (0.3 + 0.7) × 0.5 = 0.7m³

The fastness at which the water is rising is = Volume ÷ water flow rate = 0.7 ÷ 0.2 = 3.5 min = 210 seconds
