Answer:

It would be 21.6

Step-by-step explanation:

First 2% of 16000 is 320.

Now we take our wanted value of 22900 and subtract 16000 from it to get 6900.

We take our difference of 6900 and divide this by 320 and get 21.5625

That rounded to the nearest tenth is 21.6

Step-by-step explanation:

to rationalise the denominator, you need to multiply the denominator with itself and the numerator.

Answer:

The rate of the current is 2 mph.

Step-by-step explanation:

When the boat travels upstream we have:

[tex] v_{T_{1}} = v_{b} - v_{c} [/tex]                      

[tex] \frac{x_{1}}{t_{1}} = v_{b} - v_{c} [/tex]    

Where:

[tex] v_{T}[/tex]: is the total speed

[tex]v_{b}[/tex]: is the speed of the boat = 10 mph

[tex]v_{c}[/tex]: is the speed of the current

x: is the distance

t: is the time

And when the boat travel downstream we have:

[tex]v_{T_{2}} = v_{b} + v_{c}[/tex]        

[tex] \frac{x_{2}}{t_{2}} = v_{b} + v_{c} [/tex]                              

Since the boat takes 4 hours longer to travel 48 miles going upstream than it does to travel 24 miles going downstream we have:

[tex] \frac{x_{1}}{t + 4} = v_{b} - v_{c} [/tex]   (1)

[tex] \frac{x_{2}}{t} = v_{b} + v_{c} [/tex]   (2)

By adding equation (1) with (2):

[tex] \frac{x_{1}}{t + 4} + \frac{x_{2}}{t} = 2v_{b} [/tex]

[tex] tx_{1} + (t+4)x_{2} - 2v_{b}t(t+4) = 0 [/tex]

[tex] 48t + 24(t+4) - 2*10t(t+4) = 0 [/tex]

By solving the above equation for t we have:

t = 2 h      

Now, by entering "t" into equation (2) we have:

[tex] \frac{24 miles}{2 h} = 10 mph + v_{c} [/tex]  

[tex] v_{c} = 2 mph [/tex]

Therefore, the rate of the current is 2 mph.

I hope it helps you!  

Answer:

y = 4x + 12

Step-by-step explanation:

slope-intercept form is y = mx + b, where m = slope and b = y-intercept.

since you're given the values for m and b, all you need to do is plug those into the equation for slope-intercept form.

plug in 4 for m.

y = mx + b ⇒ y = 4x + b

plug in 12 for b.

y = 4x + b ⇒ y = 4x + 12

it doesn't matter which one you plug in first as long as you plug the value in for the correct variable.

the equation of your line in slope-intercept form is y = 4x + 12. i hope this helps! have a great day <3

Answer:

x = 2

Step-by-step explanation:

x = 10 = 8 | Given expression

x = 2 | Subtraction property of equality (Subtract 8 from 10.)

Answer:

10 days

Step-by-step explanation:

Mr Datu can pay 8 workers for 15 days,

Then at the same rate he can pay 1 worker for the number of days = 15×8

                                                                                                                = 120

If he adds number of workers = 4

Then total number of workers = 8 + 4 = 12

With the same rate Mr Datu can pay 12 workers for number of days = [tex]\frac{120}{12}[/tex]

                                                                                                                 = 10 days

Therefore, Mr Datu can pay 12 workers for 10 days a the same rate.

Answer:

370.85

Step-by-step explanation:

Answer:

Step-by-step explanation:

2x+6 > -14

Subtract 6 from both sides

2x > -20

Divide both sides by 2

x > -10

The solution of the inequality 2x + 6 > - 14 will be greater than the negative 10.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Six more than twice a number is greater than negative fourteen.

Let x be the number. Then the equation will be

2x + 6 > - 14

Simplify the inequality, then the value of x will be

2x > - 20

x > - 10

The solution of the inequality 2x + 6 > - 14 will be greater than the negative 10.

Answer:

[tex]y=\frac{5+8x}{10} , x=x[/tex]

Step-by-step explanation:

y-0.8x=0.5

y*10-0.8x*10=0.5*10

10y-8x=5

10y-8x+8x=5+8x

10y/10=5/10+8x/10

y=5+8x/10

5*5+8x/10-2.5

8x+5/2-2.5=4x

y=5+8x/10, x=x

Answer:

B. -3

Step-by-step explanation:

f(x) = 3x - 15

f(4) means x=4, so you want to plug 4 into the equation.

f(4) = 3(4) - 15

f(4) = 12 - 15

f(4) = -3

Answer:

B

Step-by-step explanation:

f(4) has the same meaning (for this question ) as x = 4

Let x = 4

f(4) = 3*4 - 15

f(4) = 12 - 15

f(4) = - 3
