Answer:

3rd table, 2nd table, 1st table

Step-by-step explanation:

So, the table ratios for the first at 5:10 and 6:12. Which can be simplified to 1:2, meaning 1 quart for every 2 pints.

The second table's ratios are 2:16 and 3:24. Which also can be simplified to 1:8, meaning 1 cup for every 8 fluid ounces.

The last table's ratios are 8:56 and 10:70. Which as well could be simplified to 1:7, meaning 1 week for every 7 days.

Hope this helps :)

Step-by-step explanation:

the ratio of quarts to pints is according to this table

5/10 or 6/12, which is simplified 1/2.

cups to fluid ounces

2/16 or 3/24, which is simplified 1/8.

weeks to days

8/56 or 10/70, which is simplified 1/7.

and then it is the same as for normal fractions :

1/8 is the smallest

1/7

1/2 is the largest

If four bells toll at intervals of 8,9,12 and 15 minutes respectively. If they toll at 3 pm when will they toll together

Ur basically looking for the common multiple of the numbers 8,9,12,and 15.
LCM of these numbers is 360.

so 360 minutes = (360/60) = 6 hrs

and 6 hrs from 3 p.m. would be : 9 p.m. <== ur answer

Q2. A train travels at a constant speed of 45 m/s. a) Calculate the distance travelled by the train in:

alex41 [277]

Answer:

i) 1350 m

ii) 5400 m

Step-by-step explanation:

<u>Formula for Speed</u>

$\boxed{\sf Speed=\dfrac{Distance}{Time}}$

Rearrange the formula so that Distance is the subject:

$\implies \sf Distance = Speed \times Time$

<h3><u>Question (i)</u></h3>

Given:

Speed = 45 m/s (meters per second)
Time = 30 seconds

Substitute the given values into the formula for distance:

$\implies \sf Distance = 45 \times 30 = 1350\:m$

<h3><u>Question (ii)</u></h3>

Given:

Speed = 45 m/s (meters per second)
Time = 2 minutes

As the time is given in a different unit of time as the speed, we must first convert the time into seconds:

1 minute = 60 seconds

⇒ 2 minutes = 60 × 2 = 120 seconds

Therefore:

Speed = 45 m/s (meters per second)
Time = 120 seconds

Substitute the values into the formula for distance:

$\implies \sf Distance = 45 \times 120 = 5400\:m$

Hello there!☺

$Answer:\boxed{(2x+3)(x+1)}$

$Explanation:$

$2x^2+5x+3$ Factorized

To factor $2x^2+5x+3$ , we will have to do it by grouping.

$2x^2+5x+3\\(2x+3)(x+1)$

$(2x+3)(x+1)$ is your answer.

Hope this helps!☺

Find the solutions to the system; y=x^2-3x-1 and y=8x-1

PSYCHO15rus [73]

${x}^{2} - 3x - 1 = 8x - 1 \\ {x}^{2} - 11x = 0 \\ x(x - 11) \\ x = 0 \: or \: x = 11$

When x = 0,
$y = 8x - 1 \\ y = 0 - 1 \\ y = - 1$

When x = 11
$y = 8(11) - 1 \\ y = 87$
x = 0, y = - 1
x = 11, y = 87

Answer is B.

Hope this helps. - M
