Answer:

?__________*_*__________?

Given:

y is proportional to x.

y=10 and x=8.

To find:

The constant of proportionality and the equation for the proportional relationship.

Solution:

y is proportional to x.

[tex]y\propto x[/tex]

[tex]y=kx[/tex]               ...(i)

Where, k is the constant of proportionality.

Putting y=10 and x=8, we get

[tex]10=k(8)[/tex]

[tex]\dfrac{10}{8}=k[/tex]

[tex]\dfrac{5}{4}=k[/tex]

Putting [tex]k=\dfrac{5}{4}[/tex] in (i), we get

[tex]y=\dfrac{5}{4}x[/tex]

Therefore, the contestant of proportionality is [tex]k=\dfrac{5}{4}[/tex] and the equation for the proportional relationship is  [tex]y=\dfrac{5}{4}x[/tex].

Answer:

X=20

Step-by-step explanation:

360/18=20

Answer:

x=20

Step-by-step explanation:

18x=360

divide both sides by 18x

[tex]\frac{18x}{18}[/tex]=[tex]\frac{360}{18}[/tex]

simplify

x=20

hope this helps :) have a nice day !!

0.1

Answer:

n = -11

Step-by-step explanation:

3n - 17 = -50

⇒ 3n = -33

⇒ n = -11

Answer:

n = -11

Step-by-step explanation:

3n - 17 + 17 = -50 + 17

3n = -33

3n/3=-33/3

n = -11

Answer:0.75757575757

Answer:

Fraction Form

25/33

Decimal Form

0.75

Step-by-step explanation:

First, convert the mixed fraction into an improper fraction, so it would look like:

-5/3 / (-11/5)

Next, divide. Remember, when multiplying fractions all you do is flip the one in parantheses and make both of them positive, so it would look like:

5/3 x 5/11

Finally, multiply so you do the two top numbers which is 5 x 5= 25 and the two bottom numbers so 11 x 3 is 33. Then your final answer is 25/33

12 inches, 180/30 is 6 and 2x6 is 12

Given:

The area model.

The area of the shape is 82 square units.

To find:

The correct equation for the given situation.

Solution:

We know that, area of a rectangle is

[tex]Area=Length \times Width[/tex]

The figure is divided into 3 rectangles. Using this formula, the area of each rectangle is

[tex]A_1=(x)\times (3x)=3x^2[/tex]

[tex]A_2=(x)\times (4)=4x[/tex]

[tex]A_3=(3)\times (3x)=9x[/tex]

Now, the total area is equation to 82 square units.

[tex]A_1+A_2+A_3=82[/tex]

[tex]3x^2+4x+9x=82[/tex]

[tex]3x^2+13x=82[/tex]

Since the required equation is [tex]3x^2+13x=82[/tex], therefore, the correct option is C.

Answer:

The worth of the TV after 3 years is £809.90208

Step-by-step explanation:

The answer to given question can be found from the anual depreciation formula and solving for the Future Value (F. V.) of the machine

The given parameters of the TV are;

The amount at which Collin buys the TV, P = £720

The rate at which the TV depreciates at, R = 4%

The number of years the depreciation is applied, T = 3 years

The amount the TV is worth after three years, 'A', is given as follows;

[tex]A = P \cdot \left(1 + \dfrac{R}{100} \right )^T[/tex]

By plugging in the known values, we have;

[tex]A = 720 \cdot \left(1 + \dfrac{4}{100} \right )^3 = 809.90208[/tex]

The amount the TV is worth after three years, A = £809.90208

Answer:

surface area=226.12 in^2

Step-by-step explanation:

8x3.14x5=circular area=125.6

(8/2)^2 x 3.14=0ne end of cylinder area=50.26

125.6+50.26+50.26=226.12

Answer:

4.5

Step-by-step explanation:

Answer:

£1560

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 1200 × 0.06 × 5 = 360

I = £ 360.00

The simple interest accumulated

on a principal of £ 1,200.00

at a rate of 6% per year

for 5 years is £ 360.00.

$10.50

Explanation:

Let x be the cost of the individual books. Then 24.81=3x−6.69

3x= 24.81+ 6.69 =31.50

x=31.50/3=10.50

Answer:

The expression of how Susan solved 99 × 47 is;

99 × 47 = 100 × 47 - 47

The evaluation of the expression is;

99 × 47 = 4653

Step-by-step explanation:

The question relates to the simplification of the multiplication of two numbers by the use of a combination multiplication of one of the numbers, 'x', with the nearest 10s or 100s of the other number, 'y', followed by the subtraction or addition operation of the product between the number 'x' and the difference between the specified 10s or 100s and 'y';

The given information on how Susan solved the equation 99 × 47 can be presented as follows;

99 × 47 = (100 - 1) × 47 = 100 × 47 - 47

The expression of how Susan solved 99 × 47 is therefore presented as follows;

99 × 47 = 100 × 47 - 47

The evaluation of the expression is therefore given as follows;

100 × 47 - 47 = 4700 - 47 = 4653.

Answer:

$94.12
