Answer:

V=15

Step-by-step explanation:

You have to make V the subject of the formula. Start by multiplying both sides of the problem by three to get rid of it on the left and multiply it to 8 on the right. Then carry 9 over to the answer on the right side and make sure tp change the sign to subtraction. Then carry out the operation and you have the answer.

3 (v+9/3)=(8)3

v+9=24

v=24-9

v=15

Answer:

We have to travel 26.93 units from platform B to C.

Step-by-step explanation:

Length of a segment having coordinates $(x_1,y_1)$ and $(x_2,y_2)$ is determined by the formula,

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

From the graph attached,

Coordinates of the points B and C are (-25, -20) and (-15, 5) respectively.

Distance between these points B and C Or length of BC will be,

BC = $\sqrt{(-25+15)^2+(-20-5)^2}$

= $\sqrt{100+625}$

= $\sqrt{725}$

= $5\sqrt{29}$

= 26.93 units

Therefore, we have to travel 26.93 units from platform B to C.

Write an algebraic expression to represents the verbal expression: the difference between the product of 4 and a number and the

Naily [24]

Answer:

$4n-n^2$

Step-by-step explanation:

I use 'n' as the unknown value, but you can use any letter you want as the variable.

The product of four and a number would be represented by '4 * n'. The ideal way to write this would be '4n', even though '4 * n' is also correct in value.

The square of the number would be n². Squaring a number is multiplying a number by itself.

The phrase 'difference between...' means subtraction.

Putting it together:

"The difference between the product of 4 and a number and the square of the number" would be:

$4n-n^2$

Hope this helps.

Help me please. I'm very confused

To solve this problem we must find 5% of 1418 and 4% of 1418
which is
$5 \div 100 \times 1418 \\ \ \\ 4 \div 100 \times 1418$

so that would be 70.9 house extra in the first year and 56.72 extra in the second year respectively.
so to find the total number of houses we must add 70.9 + 56.72 + 1418 which gives us 1545.62
at the last it is mentioned for us to round our answer to the nearest

they are asking us for the total number whole number
which is 1546
so there would be 1546 houses in the second year.
