the answer is a) 100*

the angles it is bigger than is an acute angle (below 90)* and a right angle (exactly 90*) so the answer is anything above 90* and so it has to be 100*

Sasha can run at an average speed of 934 9 3 4 min/mi. She runs at this speed for 6814 68 1 4 min. How many miles does Sasha run
lutik1710 [3]
I don't know what the spaces are meant for but I think that means 934 and 6814 only. Another point is, speed should be expressed in units of distance over time. So that would be miles/min.

So, distance could be calculated by multiplying speed and time.

d = 934 mi/min * 6814 min
d = 6,364,276 miles

Indicate whether the statement is true of false.
yawa3891 [41]

The statement is false, as the system can have no solutions or infinite solutions.

<h3>Is the statement true or false?</h3>

The statement says that a system of linear equations with 3 variables and 3 equations has one solution.

If the variables are x, y, and z, then the system can be written as:

a_1*x + b_1*y + c_1*z = d_1\\\\a_2*x + b_2*y + c_2*z = d_2\\\\a_3*x + b_3*y + c_3*z = d_3

Now, the statement is clearly false. Suppose that we have:

a_1 = a_2 = a_3\\b_1 = b_2 = b_3\\c_1 = c_2 = c_3\\\\d_1 \neq d_2 \neq  d_3

Then we have 3 parallel equations. Parallel equations never do intercept, then this system has no solutions.

Then there are systems of 3 variables with 3 equations where there are no solutions, so the statement is false.

What is the lcm of 6 and 8
Dafna1 [17]

Answer:

Explanation:

Method 1

First, list the multiples of both numbers:

undefined

To find the lowest common multiple (LCM) of 6 and 8, first express the numbers as a product of its prime factors.

\begin{gathered} 6=2\times3 \\ 8=2\times2\times2=2^3 \end{gathered}

Next, pick the highest powers for each of the numbers:

\begin{gathered} \text{LCM}=2^3\times3 \\ =8\times3 \\ =24 \end{gathered}
