Answer:
20% decrease
Step-by-step explanation:
First, let's find the net decrease: Peter started at 80kg and his weight is now 64kg, which is a 16kg decrease. Next, we need to find what percentage of 80kg 16kg represents. First, let's find what part of 80 is 16:
16/80 = 1/5
To convert this to a percent, we need to find an equivalent fraction to 1/5 with a denominator of 100. To do this, we can multiply the numerator and denominator of 1/5 by 20, giving us 20/100, or 20%.

Find all solutions to the following system of equations. (x-2)^2+(y+3)^2=4 and x-y=3
Equation form:
x=2, y=-1
x=0, y=-3
Use trig identities to verify this expression:
((1-tan^2(x))/(sec^2(x))=cos(2x).
Answer:
See below
Step-by-step explanation:
Verify the expression:
((1-tan^2(x))/(sec^2(x))=cos(2x)
-----------------------
(1-tan^2(x))/(sec^2(x) =(1-tan^2(x))/(1/cos^2(x) =(1-tan^2(x))*cos^2(x) =cos^2(x) - sin^2(x) = cos^2(x) - (1 - cos^2(x)) =2cos^2(x) - 1 =cos(2x)Done
100 points Explain what the slope and intercept mean in the situation.
The graph shows the cost in dollars, y, of a muffin delivery and the number of muffins, x, ordered. The slope of the line is 2 and the y-intercept is 3.
Answer:
The slope means that every time the x value changes by +1, then the y value will change by +2.
The y-intercept is 3, which means is that when the y value is at 3, the line crosses the y-axis, or x has as value of 0.
For real though, why are there so many questions about slope and intercept, I just finished answering a question like this.

Zoe paid $18.60 in sales tax and tips for her dinner. The sales tax rate is 11%and she tipped 20% (The sales tax does not apply to the tip, and the tip is based on the price of the dinner before sales tax.)
What was the price of Zoe's dinner, before sales tax and tip?
Answer:
$60 was the price of Zoe's dinner, before sales tax and tip.
Step-by-step explanation:
Sales tax + tips for dinner = 18.60
The sales tax rate is 11%, and she tipped 20%. Given that the sales tax does not apply to the tip, and the tip is based on the price of the dinner before sales tax. Let x be the original price
Sales tax = 11% * original price = 0.11 * x= 0.11x
Tips for dinner = 20% * original price = 0.20 * x = 0.2x
We know Sales tax + tips for dinner = 18.60
0.11x + 0.2x = 18.60
0.31x = 18.60
Divide by 0.31 on both sides
x = 60

Step-by-step explanation:
Let N be the universal set and A, B, C, D be its subsets given by A={x:xisaevennaturalnumber},B={x:xNandxisamultipleof3} C={x:xNandx 5},D={x:xNandx 10} Find complements of A, B, C and D respectively.
Answer:
[tex]A^{'}[/tex] = {1,3,5,7,9,....}
[tex]B^{'}[/tex] = {1,2,4,5,7,8,10,11,13,14......}
[tex]C^{'}[/tex] = {1,2,3,4,5}
[tex]D^{'}[/tex] = {10,11,12,13,14,15,......}
Step-by-step explanation:
Solution:
It is given that, Universal set is the set of all Natural Numbers.
and
Set A, Set B, Set C, Set D are subsets of Universal set.
A = {x:x is even natural numbers} = {2,4,6,8,10,.....}
B = {x:x ∈ N and x is a multiple of 3} = {3,6,9,12,15,....}
C = {x:x∈ N and x < 5} = {6,7,8,9,10,.....}
D = {x:x ∈ N and x > 10} = {1,2,3,4,5,6,7,8,9}
U = {1,2,3,4,5,6,7,8,9,10,11,........}
Complements:
[tex]A^{'}[/tex] = U-A = {1,2,3,4,5,6,7,8,9,10,11,........} - {2,4,6,8,10,.....}
[tex]A^{'}[/tex] = {1,3,5,7,9,....}
[tex]B^{'}[/tex] = U-B = {1,2,3,4,5,6,7,8,9,10,11,........} - {3,6,9,12,15,....}
[tex]B^{'}[/tex] = {1,2,4,5,7,8,10,11,13,14......}
[tex]C^{'}[/tex] = U-C = {1,2,3,4,5,6,7,8,9,10,11,........} - {6,7,8,9,10,.....}
[tex]C^{'}[/tex] = {1,2,3,4,5}
[tex]D^{'}[/tex] = {1,2,3,4,5,6,7,8,9,10,11,........} - {1,2,3,4,5,6,7,8,9}
[tex]D^{'}[/tex] = {10,11,12,13,14,15,......}

When graphing y = 3x + 5,
what is the first step?
Answer:
The first step would be to plot the y-intercept. In this equation, the y-intercept is 5. The ordered pair is (0, 5), because (x, y).
You go up 5 from the origin (the center of the graph, (0, 0) ), and plant a dot on the y-axis.
If you need help from there, then ask in the comments.

PLEASEEEEEEESE! thanks! During a company's first full year in business, the price of oil increased $50. In the second year of business, the price of oil went down $50\%$ from its price at the beginning of that year. Its price at the end of the second year is what percent of its price at the beginning of the first year?
Answer:
the actual answer is 75 percent of its price
Step-by-step explanation:
Answer:
75
Step-by-step explanation:
Let the initial cost of oil be x. After the first year, the price of oil is 1.5x. After the second year, the price of oil is 0.5 ∙ 1.5x = 0.75x.
This is 75 percent of its price at the beginning of the first year.

maria draws one marble from a bag containing 5 red, 3 green, and 4 yellow. the probability she draws a yellow marble is____
Answer:
33% or 4/12
Step-by-step explanation:
There are 5 red, 3 green, and 4 yellow, so make it into a fraction. In total there are 12 marbles(5+3+4). There are 4 yellow marbles, so the fraction would be 4/12. Turn this into a percent to get the probability. 4/12 = 0.33 = 33%
What is the value of A?
Answer:
the answer is 6 ___________________________
what is the answer to x + 5 = -6
Answer:
x=-11
Step-by-step explanation:
If you subtract the 5 on both sides, you get -11.
I should explain further. So if you subtract the 5 on the left side, it will cancel out. Subtracting the 5 on the right side will give you the equation, -6 - 5, which is equal to -11.
