8x10^3 is how many times as large as 4x10^2
Answers
Answer:
(3.2 × 10²) times as large
Step-by-step explanation:
First, set up an equation:
(8 × 10³) ÷ (4 × 10²)
Using the laws of exponents, we know that when two exponents with the same base are being divided by each other, the exponents subtract from each other:
(8 × 4) × (10³⁻²) = (32 × 10¹)
Move the decimal one space to the left, which increases the exponent by 1:
(3.2 × 10²)

Step-by-step explanation:
We have the following function:
f (x) = 3/8 (4) ^ x
The function is of the form:
f (x) = A (b) ^ x
Where,
A: initial amount

and what is the cost for a nonmember?
Part 1 out of 2
The cost per member is S
Answers
Answer:
member = 15
nonmember = 55
Step-by-step explanation:
m = member, n= nonmember
1m+6n=345
2m + 2n =140 (divide all by 2 )
m + n = 70
m= 70 - n
70-n + 6n =345
70 + 5n = 345
5n = 345-70
5n = 275
n = 275÷5
n = 55
m = 70 - 55 = 15
m=15

liliana decides to crop a square photo 2 inches on each side to fit it into a frame. the area of the original photo was 121 square inches. in the equation (x 2)2
Answers
The dimensions of the cropped photo will be 9 inches by 9 inches
Step-by-step explanation:
From the formula of area of square
Length x width = area
[tex]x^{2}[/tex] = area
But we are given the equation as
[tex](x+2)^{2}[/tex] = 121
The equation gives the measures of the cropped dimension as "x". This means we need to solve the equation
[tex](x+2)^{2}[/tex] = 121
[tex]x^{2}[/tex] + [tex]2^{2}[/tex] + 2(x) (2) = 121
[tex]x^{2}[/tex] + 4 + 4x = 121
[tex]x^{2}[/tex] + 4x -117 = 0
[tex]x^{2}[/tex] + 13x - 9x -171 = 0
x( x+13) -9 (x+13) = 0
(x+13)(x-19) =0
This means
x = 9, -13
Since, dimension can't be negative. So, the measure of dimension would be 9 inches by 9 inches

The teacher has the following cards in a bag::
what is the probability that the teacher randomly selects a card with an 8 on it?
Answers
Answer:
20% or .20
Step-by-step explanation:
There are a total of 10 cards in the sample.
Of these 10 cards there are 2 of them with the number 8 on them.
To find the probability, you divide the part (2) over the whole (10)
2/10 = .20
Then you can multiply by 100 to find the percent
(.20)(100) = 20%
Therefore, if the teacher were to select a card at random there is a 20% chance that it has the number 8 on it.
I hope this helps!

Is Figure A’B’C’D a reflection of figure ABCD ? A: yes it is a reflection over the x-axis. B: yes it is a reflection over the y-axis. C: yes it is a reflection over line f. D: no it is not a reflection
Answers
A’B’C’D' will be a reflection of figure ABCD about line f
what is a reflection about a line?A reflection over a line l(notation l) is a transformation in which each point of the original figure (pre-image) has an image that is the same distance from the line of reflection as the original point but is on the opposite side of the line.
reflection of point D will be D' if the distance between point D and line f is the same as the distance between point D' and line f
let us consider point (10,0) on line f for our convenience. we will calculate each distance from this point (10,0)
distance is 2 units from both the points D and D'
reflection of point C will be C' if the distance between point C and line f is the same as the distance between point C' and line f
distance of point C from line f= distance of point C' from line f
[tex]\sqrt{(14-10)^2 + (-2-0)^2} = \sqrt{(10-8)^2+ (4-0)^2} =\sqrt{20}[/tex]
similarly, point A and B will also be equidistant from line f
therefore, A’B’C’D' will be a reflection of figure ABCD about line f.

The value of AG is 37cm
How to determine the valueFrom the diagram shown, we have that;
AG = 3x + 3GB = 11x + 6AB = 166cmBut;
AG + GB = AB
Let's substitute the values
3x + 3 + 11x + 6 = 166
collect like terms
3x + 11x + 9 = 166
14x = 166 - 9
14x = 157
Make 'x' the subject
x = 157/ 14
x = 11. 2cm
But line AG = 3x + 3 = 3 ( 11. 2) + 3 = 33. 6 + 3 = 37cm
