The product of 9 upon 7 and a number is 63. Find the number

Alex_Xolod [135]

Answer:

heyy Vrooo....

alr ans is 49

Step-by-step explanation:

see let number be x

so as per ques.. product of x and 9/7 = 9x/7

which is 63

so $\frac{9x}{7}$ = 63

9x = 63*7

x = $\frac{63*7}{9}$

x = 7*7 = 49

Larissa practices for a swimming tournament

scoundrel [369]

Answer:

Larissa takes 59.141 seconds to complete both laps.

Step-by-step explanation:

The complete time is the sum of time taken on each lap. We translate the two statements into mathematical expressions to determine the required output:

(i) She completes her first lap in 31.135 seconds:

$x_{1} = 31.135\,s$

(ii) She completes her second lap 3.129 seconds faster than the first lap:

$x_{2} = x_{1}-3.129\,s$

$x_{2} = 31.135\,s - 3.129\,s$

$x_{2} = 28.006\,s$

Then, the time taken by Larissa to complete both laps is:

$\Delta x = x_{1} + x_{2}$

$\Delta x = 31.135\,s+28.006\,s$

$\Delta x = 59.141\,s$

Larissa takes 59.141 seconds to complete both laps.

What is the midpoint M of that line segment?

Sladkaya [172]

Answer: The midpoint M is located at (6,4)

==============================================

Explanation:

First focus on just the x coordinates of points S and T, which are 5 and 7 respectively. Add them up to get 5+7 = 12. Then divide that in half to get 12/2 = 6. This is the x coordinate of the midpoint.

Repeat for the y coordinates of S and T. First add up the values: 7+1 = 8. Then divide by 2 to get 8/2 = 4. This is the y coordinate of the midpoint.

The two results we get are then written as an ordered pair getting us the answer (6,4)
