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.

Answer:

interest earned: $105

balance of the account: $455

Step-by-step explanation:

Interest earned and The balance of the account are $105 and $455.

Given:

Amount invested = $350

Interest rate = 3% = 0.03

Number of year = 10 years

Find:

Computation:

simple interest earned = PRT

Interest earned = (350)(0.03)(10)

Interest earned = $105

The balance of the account = 105 + 350

The balance of the account = $455

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!

Follows are the solution to the given points:

Step-by-step explanation:

The brand (M) will become more reliable as the standard deviation of an (M) brand will be much lower than the standard deviation of (G) brand.

such as four years,

Calculating the z score for G brand[tex]= \frac{(4-3)}{1} = \frac{1}{1} = 1[/tex]

Calculating the z score for M brand[tex]= \frac{(4-3)}{(\frac{1}{3})} = \frac{(1)}{(\frac{1}{3})} = 1 \times \frac{3}{1}= 3.[/tex]

Because the z mark of the (G) brand is less, it is much more probable that the (G) Brand could last four years. It is because the variability of the (G) brand is very high, which allows lasting longer by expanding its expansion.

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:

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

Determine whether Rollie's theorem can be applied or not

First, find the coordinates of the endpoints on the closed interval [-1, 1]

[tex]f(x) = -x^2[/tex]

[tex]f(-1) = -(-1)^2 = -1[/tex] ------ [tex](-1,-1)[/tex]

[tex]f(1) = -(1)^2 =-1[/tex] ---- [tex](1,-1)[/tex]

Find the derivative of f(x)

[tex]f(x) = -x^2[/tex]

[tex]f'(x) = -2x[/tex]

Calculate the slope (m) of the secant line i.e. [tex](-1,-1)[/tex] and [tex](1,-1)[/tex]

[tex]m = \frac{-1 - (-1)}{1 - (-1)}[/tex]

[tex]m = \frac{-1 +1}{1 +1}[/tex]

[tex]m = \frac{0}{2}[/tex]

[tex]m=0[/tex]

Set the derivative to the calculated slope:

[tex]f'(x) = m[/tex]

[tex]-2x = 0[/tex]

[tex]x=0[/tex]

Plug in 0 for x in f'(0)

[tex]f'(x) = -2x[/tex]

[tex]f'(0) = -2 * 0[/tex]

[tex]f'(0) = 0[/tex]

Since f'(0) is differentiable at x = 0. We can conclude that Rollie's theorem can be applied

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:

x = 9

Step-by-step explanation:

Move all terms containing x to the left, all other terms to the right.

Add '-9' to each side of the equation.

9 + -9 + -1x = 0 + -9

Combine like terms: 9 + -9 = 0

0 + -1x = 0 + -9

-1x = 0 + -9

Combine like terms: 0 + -9 = -9

-1x = -9

Divide each side by '-1'.

x = 9
