Answer:
64%
Step-by-step explanation:
A coin contains 9 grams of nickel and 16 grams of copper for a total weight of 25 grams.
What percentage of the metal in the coin is copper
Solution:
The total weight of the coin = weight of copper in coin + weight of nickel in coin
The total weight of the coin = 9 g + 16 g = 25 g
The percentage of copper in the coin is the ratio of the weight of copper in the coin to the total weight of the coin expressed in percentage. It is given by the formula:
The percentage of copper in the coin = (weight of copper in the coin / total weight of the coin) * 100%
The percentage of copper in the coin = (16 g / 25 g) * 100% = 64%
Bob and Cam are scuba diving. Bob is 15 meters below the surface of the water. Cam is 4 meters above Bob.
What is Cam's position relative to the surface of the water?
Answer: -11 meters
Step-by-step explanation:
so for the waters surface, we are going to call that 0. if bob is at 15 meters below 0, then -15+4=-11, so he would be at-11 meters in relation to the waters surface.

Levi is trying to solve this problem:
"A store has a sale where every item has a sale price that is 25% less than the regular price. Write an expression that represents
the sale price of an item if the regular price is p dollars."
Levi said, "To find 25% of a number, I should multiply by 0.25. So the sale price of an item will be 0.25p."
Which statement best describes Levi's reasoning?

Write the first 6 terms of each pattern. a) Start at 100. Subtract 6 each time. b) Start at 10. Alternately, add 5 then subtract 2.
Answer: The first 6 terms startng with the first term already given for each question are a) 100, 96. 90, 84, 78,72 b) 13, 16, 19,22,25, respectively
Step-by-step explanation:
A) first 6 terms
a) Start at 100. Subtract 6 each time
First term = 100
2nd term = 100-6= 96
3rd term = 96-6=90
4th term= 90- 6= 84
5th term = 84-6= 78
6th term 78-6= 72
100, 96. 90, 84, 78,72.
b) Start at 10. Alternately, add 5 then subtract 2
First term = 10
2nd term = 10+5 -2= 13
3rd term = 13+5-2=16
4th term= 16+5-2=19
5th term = 22+5-2= 25
10, 13, 16, 19,22,25
If f(x) = 2x - 3, find f(-2).
As, f(x) = 2x - 3
Therefore, f(-2) = 2(-2) - 3
[tex]\sf : \implies f(-2) = 2(-2) - 3[/tex]
[tex]\sf : \implies f(-2) = - 4 - 3[/tex]
[tex]\sf : \implies f(-2) = - 7[/tex]
Hence, value of f(-2) is - 7.is 6 a factor of 32z+8 ?
Answer:
nope, 6 is not a factor of 32z + 8

Write the equation of the line in slope intercept form that passes through (0,8) and (-2,6)
Answer:
Step-by-step explanation:
The slope intercept form of a line is y=mx+b where m is the slope and b is the y intercept.
Slope or m is defined as m=(y2-y1)/(x2-x1) in this case
m=(6-8)/(-2-0)=-2/-2=1 now our line is
y=x+b, using point (0,8) solve for b
8=0+b, so b=8 and the line is
y=x+8
given that x = y - 2 / y -3 Express y in terms of x
Answer
y=3x-2/x-1
