What type of number is
-15/3

It would take 10 gardeners to plant 45 trees in 45 minutes.

It's a math tool for solving problems about proportion. You can relate more than 2 variables and from the proportion, it's possible to find an unknown number.

The question gives:

6 gardeners can plant 18 trees in 30 minutes.

?  gardeners can plant 45 trees in 45 minutes.

6 gardeners can plant [tex]\frac{18\; tree}{30\; min}=\frac{3}{5}[/tex] trees/min. You can calculate the second rate from   [tex]\frac{45\; tree}{45\; min}=\frac{1}{1}=1[/tex] tree/min.

Write the previous text information in form of proportion.

6 gardeners  ----------- 3/5 trees/min

x gardeners  ----------- 1 tree/min

Then, applying cross multiplication:

[tex]\frac{3x}{5}=6\\ \\ 3x=30\\ \\ x=10[/tex]

Answer:

x = -24/5

none of the options listed

Step-by-step explanation:

27=−5x+3

the choices all have x listed as a positive number, so we need to fix the question by moving 5x to the other side of the = and changing its sign.

27 +5x= 3

then move the 27

5x= 3 -27

then subtract

5x = -24

then divide both sides by 5

x = -24/5

a) The approximate reaction distance is 66 feet.

b) The approximate braking distance is 802.304 feet.

c) The total distance is 868.304 feet.

The average reaction time ([tex]t_{R}[/tex]) is 0.75 seconds. Manuel drives at constant velocity in the first 0.75 seconds, then he decelerates the vehicle.

a) The reaction distance ([tex]x_{R}[/tex]), in meters, is found by the following expression:

[tex]x_{R} = v_{o}\cdot t_{R}[/tex] (1)

Where [tex]v_{o}[/tex] is the initial velocity, in feet per hour.

If we know that [tex]v_{o} = 60\,\frac{mi}{h}[/tex] ([tex]v_{o} = 88\,\frac{ft}{s}[/tex]) and [tex]t_{R} = 0.75\,s[/tex], then the approximate reaction distance is:

[tex]x_{R} = (88)\cdot (0.75)[/tex]

[tex]x_{R} = 66\,ft[/tex]

The approximate reaction distance is 66 feet. [tex]\blacksquare[/tex]

b) A normal braking has magnitudes of about 0.15 times the value of gravitational acceleration ([tex]g = 32.174\,\frac{ft}{s^{2}}[/tex]). The approximate braking distance ([tex]d[/tex]), in feet, is found by the following kinematic formula:

[tex]d = \frac{v^{2}-v_{o}^{2}}{2\cdot a}[/tex] (2)

Where:

If we know that [tex]v_{o} = 88\,\frac{ft}{s}[/tex] and [tex]v_{o} = 0\,\frac{ft}{s}[/tex], then the approximate braking distance is:

[tex]d = \frac{\left(0\,\frac{ft}{s}\right)^{2}-\left(88\,\frac{ft}{s} \right)^{2}}{2\cdot \left(0.15\right)\cdot \left(-32.174\,\frac{ft}{s^{2}} \right)}[/tex]

[tex]d = 802.304\,ft[/tex]

The approximate braking distance is 802.304 feet. [tex]\blacksquare[/tex]

c) The total distance is the sum of distances found in a) and b). Then, the total distance is 868.304 feet. [tex]\blacksquare[/tex]

Step-by-step explanation:

Let x be his current age

[tex] \frac{3}{5} x - 4 = 0 \\ x + 5 = [/tex]

Solve the expression:

[tex] \frac{3}{5} x - 4 = 0 \\ + 4 \\ \frac{3}{5} x = 4 \\ \times \frac{5}{3} \\ x = 4( \frac{5}{3}) \\x = \frac{20}{3} \\ x = 6 \frac{2}{3} [/tex]

[tex]x + 5 \\ 6 \frac{2}{3} + 5 \\ 11 \frac{2}{3} [/tex]

Answer: Assume π = 3.14(rounded upto two decimal point)

Case I. 1 year = 365 days

2 years = 730 days

3 years = 1095 days

And .14 years = 51 days 2 hours 24 minutes

So, 3.14 years = 1146 days 2 hours 24 minuts.

Now, suppose you born in a leap-year.

Case II. 1 year = 366 days

2 years = 732 days

3 years = 1098 days

and .14 years = 51 days 5 hours 45 minutes 36 seconds

Then, 3.14 years = 1149 days 5 hours 45 minuts 36 seconds

So, yes, it is possible to be exactly π years old. At exactly 1146 days 2 hours 24 minutes or 1149 days 5 hours 45 minutes 36 seconds (in case of a leap-year born), we could have celebrate at our π years birthday.

Answer: Joining a gang will not give you more protection; it could enhance your chance of being targeted as a victim. Gang members make far less money than those who do not join gangs. Gang members usually don't get a good education, making it hard to find a good job. Gang involvement increases your risk of being arrested, having to go to court, being put on probation or parole, being jailed, injured, or even killed. Being a gang member is a dangerous thing. Often, members realize this once they have joined the gang and want to leave. It is never easy to leave a gang because as a member you have information that could be shared with authorities like the police – and as a result, get the gang members in trouble. You would always be getting in trouble with the law because you would apart of a gang group. Gangs often steal, break in peoples houses, break in to their cars and etc. Gang members leave you to take the blame so the other ones would not get caught and go to jail. Being in a gang is really bad for you because if you did didce to leave the gang then they might come and kill you and your family because they have no respect for other people.

Answer:

X=3, or X=-3   But the positive answer is X=3

Step-by-step explanation:

Rewrite the equation 5x^2+2=47

Subtract 2 from each side -----> 5x^2+2-2=47-2

Simplify   ---------> 5x^2=45

divide each side by 5 ----->  5x^2/5=45/5

Simplify x^2=9

Divide each side by using square root method -->  Sqrt(9)     - sqrt(9)

Now simplify to get X=3, or X=-3

The equations that describe the given circles are:

x^2 + y^2 = 4

x^2 + y^2 = 64

For a circle of radius R, centered at the point (a, b), the equation is:

(x - a)^2 + (y - b)^2 = R^2

In this case, we have two circles, both centered on (0, 0), but one has a radius of 2 units and the other a radius of 8 units, then we have two equations:

x^2 + y^2 = 2^2 = 4

x^2 + y^2 = 8^2 = 64

These are the two equations that describe the given circles.

By getting the exponential decay that models the situation, we will see that after 8 weeks she uses 0.12 cups.

We know that the first week, she uses 2 cups of sugar, and each week she uses removes one-third of what she used the previous week.

Then the second week she uses:

S₂ = 2 cups - (1/3)*(2 cups) = 2 cups*(1 - 1/3) = 2 cups*(2/3)

The third week she uses:

S₃ = 2 cups*(2/3) - (1/3)*2 cups*(2/3) = 2 cups*(2/3)^2

You already can see the pattern, at week x, she will use:

Sₓ = (2 cups)*(2/3)^(x - 1)

This is an exponential decay.

To get how much sugar does she uses after 8 weeks, we just replace x by 8 in the above equation:

S₈ = (2 units)*(2/3)^(8 - 1) = 0.12 cups of sugar.

First off, no sides have the same length as the others, so it cannot be an equilateral or an isoceles triangle, as it would required at least 2 sides to have the same length.

So, we're left with scalene triangle options.

There is an angle that is an obtuse angle (as it is more than 90 degrees and less than 180 degrees), so this is a scalene obtuse triangle.

Lets say we have (-1)^(1.5)

Step-by-step explanation:

(-1)^(1.5) = (-1)^(3/2)
