Answer:

Number bond: 1 times 56 = 56.

Number bond: 4 times 14 = 56.

Number bond: 7 times 8 = 56.

Step-by-step explanation:

As given,

Number bond: 1 times 56 = 56.             .......(1)

Number bond: 4 times 14 = 56.             .......(2)

Number bond: 5 times 6 = 56.              .......(3)

Number bond: 7 times 8 = 56.              .......(4)

Equation (1) represents factor pair of the number  because

1 times 56 = 1× 56 = 56

It satisfies

Equation (2) represents factor pair of the number  because

4 times 14 = 4× 14 = 56

It satisfies

Equation (3) does not represents factor pair of the number  because

5 times 6 = 5× 6 = 30

It does not satisfies

Equation (4) represents factor pair of the number  because

7 times 8 = 7× 8 = 56

It satisfies

So, the correct answer is -Number bond: 1 times 56 = 56.

                                           Number bond: 4 times 14 = 56.

                                            Number bond: 7 times 8 = 56.

8. Find the value of k, if (1-1) is a solution of the equation 3x-ky =8. Also, find the coordinates of
Yakvenalex [24]

Answer:

k = 5 and (6,2).

Step-by-step explanation:

Since (1,-1) is a solution of the equation 3x - ky = 8, so the point (1,-1) will satisfy the equation above.

Hence, putting x = 1 and y = -1 in the equation will give left-hand side = right-hand side.

So, 3(1) - k(-1) = 8

⇒ 3 + k = 8

⇒ k = 5 (Answer)

Therefore, the equation of the straight line is 3x - 5y = 8 ....... (1)

Now, putting x = 6 , then from equation (1) we get y = 2

Therefore, (6,2) is also a point on the graph of equation (1). (Answer)

When 14 is subtracted from 6 times a number, 40 is
Rzqust [24]

Answer:

4.5

Step-by-step explanation:

Let the number be x

6x-14 = 40

Add 14

6x = 40+14

6x = 54

Divide by 6

6x/6 = 54/6

x = 9

We want 1/2 of the number

1/2 of 9 is 4.5

The summer has ended and it's time to drain the swimming pool. 20 minutes after pulling the plug, there is still 45 000L of wate
jek_recluse [69]

Answer:

a) -900 L/min

b) 63000 L

c)  -900t +63000

 d) 7200 L

Step-by-step explanation:

a) You are given two points on the curve of volume vs. time:

(t, V) = (20, 45000) and (70, 0)

The rate of change of volume

= ΔV/Δt = (0 -45000)/(70 -20) = -45000/50 = -900 liters per minute

b) In the first 20 minutes, the change in volume was

(20 min)(-900 L/min) = -18000 L

So, the initial volume was

initial volume - 18000 = 45000

initial volume = 63,000 liters

c) Since we have the slope and the intercept, we can write the equation in slope-intercept form as

 V= -900t +63000.

d) now putting the number in the equation and do the arithmetic.

When t=62, the amount remaining is

= -900(62) +63000 = -55800 +63000 = 7200

Thus, 7200 L remain after 62 minutes.
