Dawson just ran 20 miles to prepare for a marathon. On his way home he stopped at Burger King and ordered 6
whoppers for $21. Write an equation to represent his order, then solve it.

Answer:

[tex]x>29[/tex]

Step-by-step explanation:

[tex]-x<-29[/tex]

Divide both sides by -1:

[tex]\frac{-x}{-1} <\frac{-29}{-1} \\x>29[/tex]

x > 21 is your answer.

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.

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

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

Answer:

D. 225 square units

Step-by-step explanation:

Multiply 2.5 by the scale factor of 6.

2.5 * 6 = 15

Then because it is a square, multiply 15*15

15 * 15 = 225

The answer is 225

Answer:

D

Step-by-step explanation:

The side length of the new square = 6 × 2.5 = 15 then its area

A = 15² = 225 units² → D

Answer:

m∠2 = 78°

Step-by-step explanation:

From the given picture,

lines 'm' and 'n' are the parallel lines and line 't' is the transverse line.

∠1 and angle with the measure of 78° are corresponding angles.

Therefore, m∠1 = 78°

m∠1 = m∠2 [Vertical angles are equal]

m∠2 = 78°

Answer:

x = 6

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

I have used b in place of x if you are confused about the variable usage.

Step-by-step explanation:

To find the middle measure (median), first order the numbers in numerical order:

9, 10, 12, 14, 15, 33

Now find the center: between 12 and 14. The number evenly spread between 12 and 14 is 13, so the best median is 13.

Answer:

11.4

Step-by-step explanation:

Given:

B = 132°

C = 23°

c = AB = 6

Required:

AC (b)

Solution:

Apply the Law of Sines

[tex] \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]

Plug in the values

[tex] \frac{b}{sin(132)} = \frac{6}{sin(23)} [/tex]

Multiply both sides by sin 132

[tex] b = \frac{6*sin(132)}{sin(23)} [/tex]

b = 11.4116041

b = AC ≈ 11.4 (nearest tenth)
