Answer:

c. 198 square feet

Step-by-step explanation:

Based on the picture I'm thinking the length of each line segment is 3ft, so each 'tile' on the surface of the figure is 9sqft.

Looking at the figure from the front and back you would see 4 tiles from each direction, same from the top and bottom (so far we have front + back + top + bottom = 4 + 4 + 4 + 4 = 16 tiles)

Looking directly from either side you would see 3 tiles each way, for 6 more tiles total, so the total number of tiles covering the figure is 16 + 6 = 22 tiles

Each tile is 9sqft, so total area is 22(9) = 198 sqft

Answer:

40 unit^2.

Step-by-step explanation:

Area = 1/2 * base * altitude

= 1/2 * 8 * 10

= 40 unit^2.

Answer:

The number is 13 /24

Step-by-step explanation:

Let the number = x

x - (- 11/12) = 3x - 1/6

x + 11/12 = 3x - 1/6

Collect like terms ;

x - 3x = - 1/6 - 11/12

-2x = (-2 - 11) / 12

-2x = - 13 / 12

-2x(12) = - 13

-24x = - 13

x = 13 / 24

Step-by-step explanation:

Im not sure if this is right, but I think that is the answer

If we solve each of the expression then (n-p) will have the lowest value.

Expression is like an equation and it is not only in the equal to type but only without equal to type. (n-p), np are the expressions.

We have the following expression and we have to first solve if n is a negative number and p is a positive number.

Let n=-1 and p=2

So, n-p=-1-2=-3

[tex]n^{2} p[/tex]=2

[tex](np)^{2}[/tex]=4

p-2n=0

[tex](n-p)^{2}[/tex]=9

Hence the lowest value is of n-p which is -3.

Step-by-step explanation:

Yes it might well do, but if it does, it needs something on the other side of wherever you put the equal sign.

6x - 7 is all you have so far and you have no idea what comes next. As it is, what you wrote is an algebraic expression.

Answer:

The first box in the girl row is 18, the second one in the boy row is 8, and the bottom one is also 18.

Step-by-step explanation:

To get 81 to 9, you have to divide by 9, which means you have to do the same to 72. You get the ration 9 to 8, 9 being girls and 8 being guys. Then to get from 8 guys to 16, you have to multiply by 2, which means you do the same to 9 and get the answer of 18 girls. Hope this helps :)

Answer:

11

Step-by-step explanation:

4 times 2 less than the number is equal to 4 * (x-2).

3 * one more than the number is equal to 3 * (x+1).

you get 4 * (x-2) = 3 * (x+1).

distribute the multiplication on each side of the equation to get:

4x - 8 = 3x + 3

subtract 3x from both sides of the equation and add 8 to both sides of the equation to get: 4x - 3x = 3 + 8

combine like terms to get x = 11.

that's your solution.

4 * (x-2) is equal to 4 * (11 - 2) which is equal to 4 * 9 which is equal to 36.

3 * (x+1) is equal to 3 * (11 + 10 which is equal to 3 * 12 which is equal to 36.

your solution is that the number is equal to 11!

Answer:

a) y = 63/x

b) y = 3

Step-by-step explanation:

Inverse proportionality between two variables means that if one of them increases, then the other one decreases.

These type of relationships can be written as:

y = k/x

Now we know that when y =7, x = 9

Then we can replace these two values and find the value of k.

7  =k/9

7*9 = k

63 = k

The our relationship is:

y = 63/x

This is the solution to a).

Now let's go with b)

We want to find the value of y when x = 21. then we just need to replace x by 21 in the equation "y = 63/x"

We will get:

y = 63/21 = 3

When x = 21, y is equal to 3.
