*Correct Question:

Which relationships have the same constant of proportionality between y and x as the equation 3y=27x?

Answer:

A, B, C

Step-by-step explanation:

Given that [tex]3y=27x[/tex], we can simplify to get a proportionality statement that exists between X and y. Thus

[tex]3y=27x[/tex]

Divide both sides by 3

[tex]\frac{3y}{3}=\frac{27x}{3}[/tex]

[tex]y=9x[/tex]

Thus, we can say, y would always be 9 times the quantity of x.

From the options given, examine which options have this proportionality statement as well.

Option A, y = 9x is same as the statement.

Option B, 2y = 18x, conforms to the same statement. If we simply further, we would have y = 9x

Option C, the graph shows that when x = 1, y = 9. This also confirms to the same constant of proportionality in the given equation.

Option D and E do not have same constant of proportionality.

The right options are A, B, and C.

Step-by-step explanation:

Alonso should work for 38 hours to earn $554.80.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
Alonso earned $204.40 at his job when he worked for 14 hours.
Let Alonso per hour be x,
x = 204.40 / 14
x = 14.6

Now,
Alonso works for hours to earn $554.80,
= total pay/pay of an hour
= $554.80 / 14.6

= 38

Alonso should work for 38 hours to earn $554.80.

Thus, Alonso should work for 38 hours to earn $554.80.

In order to solve this problem, we need the ratio. Please give me the ratio, so that I can help you ASAP. Thanks!

Answer:

179 R 1584

6 × 384

6 × 4 = 24(carry the 2)

6 × 8 + 2 = 50(carry the 5)
6 × 3 + 5 = 23

Put it all together into one number

23 + 0 + 4 = 2,304

3,856 + 284

6 does not add to 4 so it's 0

5 + 8 = 14(carry the 1 and add 1)

8 cannot add onto 2 so use the one you borrowed and carry. = 1

3 + 1 = 4

Put it together

4 + 1 + 4 + 0 = 4,140

414,000

Simply add the two 0's in 100 to 4,140

414,000 ÷ 2,304

Turn 4,140 into the thousands place temporarily.

4140

(a) The differential equation is separable, so we separate the variables and integrate:

[tex](x+1)\dfrac{dy}{dx} = xy \implies \dfrac{dy}y = \dfrac x{x+1} \, dx = \left(1-\dfrac1{x+1}\right) \, dx[/tex]

[tex]\displaystyle \frac{dy}y = \int \left(1-\frac1{x+1}\right) \, dx[/tex]

[tex]\ln|y| = x - \ln|x+1| + C[/tex]

When x = 0, we have y = 2, so we solve for the constant C :

[tex]\ln|2| = 0 - \ln|0 + 1| + C \implies C = \ln(2)[/tex]

Then the particular solution to the DE is

[tex]\ln|y| = x - \ln|x+1| + \ln(2)[/tex]

We can go on to solve explicitly for y in terms of x :

[tex]e^{\ln|y|} = e^{x - \ln|x+1| + \ln(2)} \implies \boxed{y = \dfrac{2e^x}{x+1}}[/tex]

(b) The curves y = x² and y = 2x - x² intersect for

[tex]x^2 = 2x - x^2 \implies 2x^2 - 2x = 2x (x - 1) = 0 \implies x = 0 \text{ or } x = 1[/tex]

and the bounded region is the set

[tex]\left\{(x,y) ~:~ 0 \le x \le 1 \text{ and } x^2 \le y \le 2x - x^2\right\}[/tex]

The area of this region is

[tex]\displaystyle \int_0^1 ((2x-x^2)-x^2) \, dx = 2 \int_0^1 (x-x^2) \, dx = 2 \left(\frac{x^2}2 - \frac{x^3}3\right)\bigg|_0^1 = 2\left(\frac12 - \frac13\right) = \boxed{\frac13}[/tex]

mean=(a+b+c+d+e+f+g)/7

Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm. If all the scoops are evenly distributed, they would all be 3.8 cm tall.

The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.

If the data set consists of values

x_1, x_2, ..., x_n

, then we get the mean value as:

[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]

Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm.

[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]

mean=[tex]\dfrac{(a+b+c+d+e+f+g)}{7}[/tex]

Therefore, If all the scoops are evenly distributed, they would all be 3.8 cm tall.
