In a appropriate environment, guppies reproduce at an astounding rate. A population of reproducing guppies quadruples every month. How many Guppies will there be after 6 months if the beginning population is only 6 guppies?a)24,576
b)144
c)46,656
d)1,296

Please help! I don't understand!

Answers

Answer 1
Answer:

Answer: a)24,576

Step-by-step explanation:

Given: A population of reproducing guppies quadruples every month.

The population of guppies in the beginning = 6

In First month, the population of guppies = 4*6=24

In Second month, the population of guppies =4*24=4*4*6=4^2\cdot6=96

Continue like this,

In 6 months, the population of guppies =4^6\cdot6=24576
Answer 2
Answer:
6x4=24 guppies 1st month
24x4=96 guppies 2nd mo.
96x4=384 ,3rd mo.
384x4=1,536, 4th mo.
1,536x4=6,144, 5th mo.
6,144x4=24,575, 6th mo.
So, A.

ark found a shirt on sale for 25% off. When he brought it to the register, he discovered that all items in the store were on sale for an additional 20% off. He wrote this expression to represent the final cost of the shirt based on the original price, p. (1−0.2)(1−0.25)p When Mark simplifies this expression, what can he conclude about the sale price of the shirt?

Answers

Answer:

The sale price of the shirt is 45% of the original price.

Rico thinks of a number between 30 and 40 that is represented by x
.
•
This number,
x
, is
3
_
4
of another number, which is represented by
y

•
The number represented by
y
equals
1
_
3
of another number, which is
represented by
z
.
•
The number represented by
z
is a number from 140 to 151.
•
The numbers represented by
x
,
y
, and
z
are whole numbers.
(a)
What are the values for
x
,
y
, and
z
?

Answers

Hello,

x,y,z∈ IN

x=(3)/(4)*y
y=(1)/(3)*z

140<z<151\ ==>\ (140)/(3)<(z)/(3)<(151)/(3)
46\leq\ y\ \leq\ 50 ==>\ (46*3)/(4)\leq(3y)/(4)\leq(50*3)/(4)
35\ \leq\ z\ \leq\ 37==>
 x∈{35,36,37}
 y∈{47,48,49}
 z∈{141,144,147}

We must go futher:

if x=35 then y=4*35/3=46.666 not good , not whole
if x=36 then y=4*36/3=48 ok
if x=37 then y=37*4/3=49.333.. not good

So there is only one solution (36,48,144) for (x,y,z)

No problem with z for z=3/1*4/3*x=4x ==>whole.

Simplify the expression. (8 + 7a) + 4 7a

Answers

For this one I'm going to assume that 4 7a means 4 * 7a...

(8 + 7a) + 4 * 7a =
8 + 7a + 28a =
8 + 35a

If I read it wrong and 4 7a is actually 47a then...

(8 + 7a) + 47a =
8 + 54a =
2(4 + 27a)

Why does the term angle need to be defined prior to defining perpendicular lines?

Answers

Answer:

Perpendicular means "at right angles".

A line meeting another line at a right angle, or 90° is said to be perpendicular to it.

This is why we need to know what are angles first.

Angles are defined as the space between two intersecting lines close to the point where they meet.

So, when we say perpendicular lines meet at 90° angles, we must know the definition of angles.

Perpendicular lines are two or more lines that intersect at a 90-degree angle, like the two lines drawn on this graph, and the x and y axes that orient them.

 

Use the discriminant to determine the number of solutions of the quadratic equation, and whether the solutions are real or complex. Note: It is not necessary to find the roots; just determine the number and types of solutions.2x^2 + x - 1 = 0
4/3x^2 - 2x + 3/4 = 0

Answers

Discriminant is b²-4ac in a quadratic equation Ax²+ Bx+C=0.

If the value of discriminant is less than zero, then the equation has two complex solutions
If the value of the discriminant is equal to zero, then the equation has one solution
If the value of the discriminant is more than zero, then there will be two real solutions.

Just plug in your values and you'll get the right answers.
