Solve. −35x+15>720 Drag and drop a number or symbol into each box to show the solution.

vampirchik [111]

Answer:

The solution of the inequality - 35x + 15 > 720 is $x$

Step-by-step explanation:

Consider the given inequality

- 35x + 15 > 720

Subtract both side by 15 , we get

- 35x + 15 - 15 > 720 - 15

- 35x > 705

Multiply both sides by -1 (Reverse the inequality )

(-35x)(-1) < 705 (-1)

35x < -705

Now, divide both side by 35

$\frac{35x}{35}=\frac{-705}{35}$

$\Rightarrow x=\frac{-141}{7}$

Thus, the solution of the inequality - 35x + 15 > 720 is $x$

There is a bag with only milk and dark chocolates. The probability of randomly choosing a dark chocolate is 5 12 . There are 40

Maksim231197 [3]

Answer:

There must be 96 milk chocolates.

Step-by-step explanation:

If you take the original ratio, 5:12, and replace the 5 with 40, you'd discover that 40 divided by 5 is 8. So what do you do? You multiply the 12 by 8 to get 96 so now the ratio is 40:96.

An automobile manufacturer has given its van a 47.2 miles/gallon (MPG) rating. An independent testing firm has been contracted t

Romashka-Z-Leto [24]

Answer:

Test statistic = 1.664

Step-by-step explanation:

The hypothesis :

H0 : μ = 47.2

H1 : μ ≠ 47.2

Given that :

Sample mean, xbar = 47

Sample size, n = 250

Standard deviation, σ = 1.9

The test statistic :

(xbar - μ) ÷ (σ/√(n))

T = (47 - 47.2) ÷ (1.9/√(250))

T = (0.2 / 0.1201665)

Test statistic = 1.664

Solve the initial-value problem<br><br> y' = x^4 - \frac{1}{x}y, y(1) = 1.

natta225 [31]

The ODE is linear:

$y'=x^4-\dfrac yx$

$y'+\dfrac yx=x^4$

Multiplying both sides by $x$ gives

$xy'+y=x^5$

Notice that the left side can be condensed as the derivative of a product:

$(xy)'=x^5$

Integrating both sides with respect to $x$ yields

$xy=\dfrac{x^6}6+C$

$\implies y(x)=\dfrac{x^5}6+\dfrac Cx$

Since $y(1)=1$ ,

$1=\dfrac16+C\implies C=\dfrac56$

so that

$\boxed{y(x)=\dfrac{x^5}6+\dfrac5{6x}}$

A certain population has been shown to have a 2% annual growth rate. The

DochEvi [55]

Answer:

The population after 10 years will be 90,000.

Explanation:

2% of 75,000 is 1,500

the population will grow by 1,500 each year.

so 1,500 times 10 is 15,000

so than we add 75,000 + 15,000

we get the answer of 90,000.
