A landscaper needs to fill a path measuring 2 feet by 8 feet with patio stones.
The patio stones are each 1 foot by 2 feet, so the landscaper calculates that she
will need 8 of them.
Before arranging the patio stones, the landscaper wants to look at all her options.
She can not cut or overlap the stones, and they all must fit inside the path area
without any gaps. Two possible arrangements of the stones are shown below.
How many different arrangements are there in total?

What is the equation of the line that passes through the point (-5, 7) and
has a slope of - 1/5?
Answers
Answer:
[tex]y=-\frac{1}{5}x+6[/tex]
Step-by-step explanation:
We have the following equation
y=mx+b
where m is the slope
and b is the y intercept
we know that the slope is -1/5 (or -.2)
which means that so far our equation looks like this
y= -.2x+b
which means we need to solve for b
we know that when x= -5 y= 7 which means we can plug in those values and solve for b
we have
7= (-.2*-5)+b
7=1+b
b=6
which means our equation is as follows
y= -1/5x+6

Select the quadratic equation that has no real solutions. 25x-10x+4=0
Answers
Answer:
Step-by-step explanation:
Were there not several equations from which to choose?
The coefficients of 25x^2 - 10x + 4 are {25, -10, 4}. The discriminant is thus b^2 - 4ac, or (-10)^2 - 4(25)(4), or 100 - 400, or -300. Because the discriminant is negative, the quadratic has no real solutions.
The quadratic equation with no real solution is 25x²-10x+4 = 0
What is a quadratic equation?The meaning of quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.
Given that, which of the equations have no real solution,
Considering the quadratic equation 25x²-10x+4 = 0
D = [tex]\sqrt{b^{2} -4ac}[/tex]
We know, when √D > 0, real roots
√D = 0, equal roots
√D < 0, imaginary roots
[tex]\sqrt{b^{2} -4ac}[/tex] =
[tex]\sqrt{10^{2} -400} \\\sqrt{-300}[/tex]
Since, the discriminant is less than 0, therefore, its roots are imaginary.
Hence, The quadratic equation with no real solution is 25x²-10x+4 = 0

Step-by-step explanation:
Multiply each term inside the ( ) by the 5 outside the ( ).
5 x 2a = 10a
5 x -6b = -30b
5 x 8 = 40
Add the terms together (don't forget that it's negative 30b)
10a + -30b + 40 = 10a - 30b + 40

A group of researchers wants to develop an experiment to determine whether a new drug effectively treats cancer. The researchers want to inject the drug in hamsters first to determine whether there are any potential serious side effects.
Part A: what are some possible ethical issues to this type of testing?
Part B: while conducting the experiment, the researchers find the cancer stops spreading, and they declare the new drug is responsible. Is this a good assumption? Explain.
Answers
Part A: The animals are used for examining and determining the effect of a particular new drug for the treatment of the diseases and disorders before they are examined over humans. This practice is called as clinical trial.
The ethical issue associated with given type of testing is that animals have right to live and survive. They should not be subjected to the treatment where they experience harm or even death.
Part B: Those assigned to the control take a sugar pill. The only thing you want to vary across groups when you're conducting an experiment is the treatment. Since taking pills is a part of taking medication (the treatment), medical experiments often employ something called a placebo-controlled study where outcomes for those who are randomly assigned to take the medication are compared to outcomes for those who are randomly assigned to take a sugar pill. The sugar pill is expected to have no effect, so it serves as a useful baseline to compare the treatment to.

Substitute in y: 2x - 32 = 2(-4x + 16)Distribute 2: 2x - 32 = -8x + 32[Addition Property of Equality] Add 8x on both sides: 10x - 32 = 32[Addition Property of Equality] Add 32 on both sides: 10x = 64[Division Property of Equality] Divide 10 on both sides: x = 32/5Step 3: Solve for y

Step-by-step explanation:
The triangle is a right triangle, as denoted by the red square at the bottom, we can use the Pythagorean Theorem to figure out the second side (since we are given the other side and the hypotenuse).
a² + b² = c²
(8)² + b² = (10)²
64 + b² = 100
b² = 100 - 64 = 36
b = ±[tex]\sqrt{36}[/tex]
b = ± 6
But we know that distance is always positive, so
b = 6
