Answer:

The answer is false or "impossible"

Step-by-step explanation:

Heres why I say this:

If the “average speed” in one hour make the car travel 50km, it means the speed could not be constant. So, it could be 90km/h during the first 30 minutes and 10km/h during the second 30 minutes. If this is the case, for example, in the next 12 minutes after the first hour, the car could be traveled 18km at 90km/h, completing 50 + 18 = 68km. The tricky word “average” makes it impossible to answer. Good try, but no cigar.

There is a 2 in 3 chance the pointer will not land on c or d.

6√3

Step-by-step explanation:

6 is x. side across from right angle (12) is 2x. so 6x2 to get 12. missing side is x√3. so 6√3

Answer:

6√3

Step-by-step explanation:

using the pythagorean theorem you can plug in the numbers to get √(12^2 - 6^2) = √(144-36) = √108 = 6√3.

Answer:

116.6

Step-by-step explanation:

Answer:

116.6

Step-by-step explanation:

To solve this equation you would need to use the pythagorean theorem. The pythagorean theorem is [tex]a^{2} +b^{2}= c^{2}[/tex] where a and b are lengths of the triangle and c is the hypotenuse (the longest side of a triangle) in this case, the short cut.

First, you would substitute values into the equation:

[tex]100^{2}+60^{2}= c^{2}[/tex]

Then, you would multiply out the squares:

[tex]10,000+3600=c^2[/tex]

Add the numbers together:

[tex]13600=c^2[/tex]

Take the square root of both sides to get the answer:

[tex]c=116.619037897[/tex]

Then round to the nearest tenth to get the answer: c=116.6

Answer:

y = 1.6

Step-by-step explanation:

4.8/3=1.6

3*1.6=4.8

Answer:

[tex]y = 1.6[/tex]

Step-by-step explanation:

[tex]3y = 4.8[/tex]

Use inverse operations to solve this problem. Inverse operations is a method of solving a linear (and in some cases quadratic) equation. This method has one do the same operations to both sides such that it cancels out the operations done to the variable, and hence, it leaves one with the solution.

In this case, all one has to do is divide both sides by the coefficient of the varibale (y).

[tex]3y = 4.8[/tex]

÷[tex]3[/tex]

[tex]y = 1.6[/tex]

Step-by-step explanation:

Answer:

I am assuming c2, is c^2.

3 × (c2 − 8)

=3 ×(3^2-8)

=27-8

=19

If c2 is c*2

Then,

3 × (c2 − 8)

=3×(6-8)

=18-24

=(-6)

Answer:

70%

Step-by-step explanation:

1. 1400÷2000 = 0.07

2. move the decimal over 2 spaces for a percentage 0.07 --> 70.0

3. 70.0 = 70%

Answer:

Step-by-step explanation:

Like terms have same variable with same exponent. Combine the like terms.

x + x = 2x  {Just add the coefficient}

x + y + x +y + 30 + 5 = x +x  +  y + y   + 30 + 5

                                 = 2x + 2y + 35

Answer:

f(0) = 2

Roots are;

-2 and -1

Step-by-step explanation:

F(0) simply refers to the y-values when x = 0

This is the point at which the graph crosses the y-axis

the value here is 2

To

find the roots of f(x) , we simply find the points at which the plot crosses the x-axis

we have this at x = -2 and x = -1

These are what represents the roots of the equation

The answer is 6.

Step-by-step explanation:

So basically, since we know that 4 x 4 is 16, then all we have to do is multiply 1 1/2 by 4. 1 1/2 times 4 equals 6.

Answer:

6 pages

Step-by-step explanation:

all you have to do is multiply 1 1/2 by 4 if 4x4 =16

Answer:

250

Step-by-step explanation:

-17+n/5=33

n/5=33-(-17)

n/5=33+17

n/5=50

n=50*5

n=250

n=182

Step by Step Explanation:

The equation we would start out with is:

[tex] \frac{ - 17 + n}{5} = 33[/tex]

From here, we need to multiply both sides by 5. This would create an equation of -17+n=165, as we canceled out the 5.

Then, you need to add 17 to both sides to isolate the variable. This would make the equation n=182, our final answer.
