Answer:
400 pounds
Step-by-step explanation:
Question: 80 is 20% of what?
Formula = a = p* w
w (whole) = a/p
a/p = 80/0.20 (decimal form of 20%)
The initial weight was 400 pounds. It should be the answer so I hope this helps.

Write a function in terms of t that represents the situation.
An item costs $4.50, and its price increases by 3.5%
each year.
Answer:
4.5(1.035)^t
Step-by-step explanation:
An inrease of 3.5% means that each year's total is 103.5% of the year before, right?
Year 1 = 4.5(1.035) = 4.66
Year 2 = 4.66(1.035) = 4.82
etc.
So, year 2 is 4.5(1.035)(1.035) = 4.82
Multiplying something by itself can be written with an exponent instead, so 2 years is...
4.5(1.035)2
Since the number of years is the variable (let's call it t)...

pls help me with my homework
Answer:
[tex] \frac{1}{81} [/tex]
Step-by-step explanation:
express that with a positive exponent using this:
[tex] {a}^{ - n} \frac{1}{ {a}^{n} } [/tex]
so ..
[tex] {9}^{ - 2} = \frac{1}{ {9}^{2} } [/tex]
now you have to evaluate the exponent/ power
so..
[tex] \frac{1}{ {9}^{2} } = \frac{1}{81} [/tex]
why 81 ?
because the exponent of 9 is 2 so you have to multiple 9 by itself so
9x9=81
so the answer is
[tex] \frac{1}{ {81}^{} } [/tex]
sorry for the bad english hehe
PLS help me pls pls pls
Write an expression to show the final cost, in dollars, of x games when using the coupon.
Answer:
5x + 2.50 - 0.2
Step-by-step explanation:
The 5x is because each game (x) costs 5 dollars. You add 2.50 because that is how much extra you have to pay for the bowling shoes. To compensate for the -20% off of the total price, I added the -0.2 (20% as a decimal).
Note:
I am 100% sure about the "5x + 2.50 -" part. The 0.2 part not so much.
I hope this is correct and helps though!

simplify imaginary number i^25
Answer:
Step-by-step explanation:
i² = -1
i⁵ = i² * i² * i
= (-1) * (-1) * i
i⁵ = i
i²⁵ = i ⁵ˣ⁵ = (i⁵)⁵
= (i)⁵
= i

select the equivalent expression. (a^-2 • 8^7)^2
a. 8^9
b. (8a)^10
c. a^-4 • 8^14
Answer:
c.
Step-by-step explanation:
The equivalent expression of [tex](a^{-2}.8^{7} )^{2}[/tex] is [tex]a^{-4} .8^{14}[/tex].
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:
Constant: A constant is a fixed numerical value.
Variable: A variable is a symbol that doesn't have a fixed value.
Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.
Coefficient: A coefficient is a number that is multiplied by a variable in an expression.
Given expression
[tex](a^{-2}.8^{7} )^{2}[/tex]
Using formula [tex]a^{-m} =\frac{1}{a^{m} }[/tex]
= [tex](\frac{8^{7} }{a^{2} } )^{2}[/tex]
= [tex]\frac{(8^{7}) ^{2} }{(a^{2}) ^{2}}[/tex]
Using [tex](a^{m} )^{n} =a^{m \times n}[/tex]
= [tex]\frac{8^{14} }{a^{4} }[/tex]
= [tex]a^{-4} .8^{14}[/tex]
Option C is correct.
The equivalent expression of [tex](a^{-2}.8^{7} )^{2}[/tex] is [tex]a^{-4} .8^{14}[/tex].

Answer:
packages: 1 grams: 11.6
packages:8 grams:92.8
grams: 116 packages: 10
Step-by-step explanation:
for the first, just divide 23.2/2=11.6
the grams of a package is 11.6
1x11.6=11.6
8x11.6=92.8
116/11.6=10

Complete the equation for the horizontal line that passes through (5, -7)
y=
Answer:
y = - 7
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (5, - 7 ) with y- coordinate - 7 , then
y = - 7 ← equation of line

Consider this dilation. Answer each question below and explain your reasoning.
Step 1: Is the image of the dilation a reduction or an enlargement of the original figure? Explain.
Answer:
It's actually an enlargement of the figure.
Step-by-step explanation:
Because if the figure originally was M' (-2,2), S' (4,2), V' (2, -2). And now the shape is M (-3, 3), S (6, 3), V ( 3, -3). This means that the Triangle got bigger.
The scale factor of the smaller shape inside of the bigger shape is 2 and the scale factor of the bigger shape is 3 making the bigger shape well bigger.

Consider a graph (not pictured) of a quadratic function g(x).
Which statement would be true of the graph of the function g(x+2)?
a.) The graph of g(x+2) is the result of a shift in the positive y-direction by 2 from the graph of g(x).
b.) The graph of g(x+2) is the result of a shift in the negative y-direction by 2 from the graph of g
c.) The graph of g(x+2) is the result of a shift in the positive x-direction by 2 from the graph of g
d.) The graph of g(x+2) is the result of a shift in the negative x-direction by 2 from the graph of g
Answer:
The answer is (B)
Step-by-step explanation:
Answer:
(D)
Step-by-step explanation:
The graph of g(x + 2) is the graph of g(x) shifted 2 units to the left
2 units to the left => "negative two units in the x-direction"
