[tex]m \times m = {m}^{1} \times m[/tex]
[tex] {m}^{1} \times {m}^{1} = {m}^{1 + 1} = {m}^{2} [/tex]

A baby panda born at a national zoo weighed 8 ounces at birth and reached 75 pounds
at one year
What was the panda's growth rate per month? Per week?
of age.
Here, we need to find the monthly and the weekly growth rate
The monthly growth rate is 99.33 ounces and the weekly growth rate is 22.9 ounces
Weight at birth = 8 ounces
Weight at one year =75 ounces
1 pound = 16 ounces
75 pounds = 1200 ounces
Additional weight after birth = Weight at one year - Weight at birth
= 1200 ounces - 8 ounces
= 1,192 ounces
There are 12 months in a year
Growth rate per month = Additional weight after birth / 12
= 1,192 / 12
= 99.33 ounces per month
There are 52 weeks in a year
Growth rate per week = Additional weight after birth / 52
= 1,192 / 52
= 22.9 ounces per week

Which rational number is closest to zero 45/17 90/19 63/10 171/112 85/18
9514 1404 393
Answer:
171/112
Step-by-step explanation:
It can be helpful to write these as mixed numbers.
45/17 = 2 11/17
90/19 = 4 14/19
63/10 = 6 3/10
171/112 = 1 59/112
85/18 = 4 13/18
Then the ordering would be ...
0 < 1 59/112 < 2 11/17 < 4 13/18 < 4 14/19 < 6 3/10
The number closest to zero is 1 59/112 = 171/112.

A store advertises “buy one, get one half-off" for a new pair of figure skates. If the skates originally cost
$88, how much would you pay for 10 pairs
A store advertises,
"Buy one and get one half off"
Which means if we buy one, half the price of one will be discounted.
In other words "50% discount on each item we buy"
We will $440 for 10 skates.
Original cost of skates = $88
After 50% discount price of one skate = $88 - $44 = $44
Cost of 10 pairs of skates = 44 × 10
= $440
Therefore, we will pay $440 for 10 skates.

Answer:

Step-by-step explanation:
You purchased a new graphing calculator for the total cost of $103.44, which includes the 10% sales tax.
What was the original price of the calculator?
The original price of the calculator is $94.04
The total cost includes a 10% sales tax on the original cost.
Assume the original cost is denoted by "c" then the correct expression would be:
Total cost = Original price x ( 1 + 10%)
103.44 = c x (1 + 10%)
103.44 = 1.1c
c = 103.44 / 1.1
c = $94.04
Original price was $94.04

Determine which of the given points are on the graph of the equation.
Equation: x² + y2 = 2
Points: (1, -1), (-1,0), (1,1)
Which of these points are on the graph of the equation? Select all that apply.
A. (1, -1)
B. (1,1)
C. (-1,0)
D. None of the points are on the graph.
Answer:
D. none
Step-by-step explanation:
to figure out if the point is on the graph, take the x value and plug it in to the x coordinate, do the same for y. if the values truly add up to 2, then it is on the graph. Since none of the values add up to 2, they are not on the graph.
One angle of a triangle measures 102°. The other two angles are congruent.
Enter and solve an equation to find the measure x of the congruent angles.
An equation is_______ = 180.
The congruent angles each measure _______°.
Answer:
if i am rightthe two other angles arre 39
Step-by-step explanation:
if a triganle is 180 degrees and you have already one angle then all you do is subtract 180 and 102
180-102= 78
then since you need the other two angles all you do is divide it by 2
so 78/2= 39 so the two missing anlges are 39

List all the elements of the following set. Use set notation and the listing method to describe the set. { 2,4,8,...,256}
All the elements of the given set {2,4,8,...,256} are - {2, 4, 8, 16, 32,64, 128, 256} that are total 8 in numbers.
The set is formed by the number of objects in a particular manner, these objects are called elements of the set. The elements of the set are written inside a curly bracket separated by a comma in a particular or specific order.
There are two methods to represent the set and its elements that are:
Set notation: define the elements and properties of sets using symbols that help in describing the relationship between elements in the set.in this case, {[tex]2^{1},2^{2},2^{3},2^{4},2^{5},2^{6},2^{7},2^8[/tex]} as we know,
so the set notation would be :
= {x:x = [tex]2^{n}[/tex], n∈N and 1 ≤ n ≤ 8}
listing method: simple method that include the members or elements of the set are written as a list, separated by the comma and enclosed within the curly braces.The listing method: {2, 4, 8, 16, 32,64, 128, 256}\

You can easily imagine a circle around your graphic. And then you remember that a circle has a total of 360 degrees all the way around the center.
This means that the following sum 4x + 2x + 3x = 360
⇔ 9x = 360
We divide both side by 9 and we get :
⇔ x = 360 / 9 = 40
So X value is 40°.

Please answer ASAP question is in pic^
Answer:
Step-by-step explanation:
Original equation
√x+6-4 = x
Isolate
√x+6 = 4+x
Raise both sides to the second power
(√x+6)2 = (4+x)2
After squaring
x+6 = x2+8x+16
Rearranged equation
x2 + 7x + 10 = 0
This equation has two rational roots:
{x1, x2}={-2, -5}
Original equation, root isolated
√x+6 = 4+x
Plug in -2 for x
√(-2)+6 = 4+(-2)
Simplify
√4 = 2
Solution checks !!
Solution is:
x = -2
Original equation, root isolated
√x+6 = 4+x
Plug in -5 for x
√(-5)+6 = 4+(-5)
Simplify
√1 = -1
Solution does not check
1 ≠ -1
