Answer:
5n + 25q = 200 - - - (1)
n = 5q - - - (2)
q = 40
n = 5(40) = 200
Step-by-step explanation:
Number of Nickels = n
Number of Quarters = q
$2.00 = $2 * 100 = 200 cent
Nickel = 5 cent
Quarter = 25 cent
5n + 25q = 200 - - - (1)
n = 5q - - - (2)
5(5q) + 25q = 200
25q + 25q = 200
50q = 200
q = 200/5
q = 40
n = 5(40) = 200
HELP FOR BAINLIST PLEAEEEE
Answer:
its 2.3
Step-by-step explanation:
Find the value of the variable(s). If your answer is not an integer, leave it in simplest radical form.
x=10/3 x=10,y=30/3 x=30.y=10/3
Answer:
Use the fact that sin(x) = opp/hyp and tan(x) = opp/adj
where opp=opposite, hyp=hypotenuse, adj=adjacent and recall sin(30)=1/2 and tan(30) = 1/sqrt(3)
sin(30) = 1/2 = 17/y
y = 17(2) = 34
tan(30) = 1/sqrt(3) = 17/x
x = 17sqrt(3)
So the answer is (d)
Note that you could have also use the Pythagorean theorem to find x instead of using tan(30).

Which expression is equal to 21/48?
a. 1/2 x 11/48
b. 7/12 x 3/4
c. 3/48 x 7/48
d. 10/6 x 11/8
Answer:
option b
Step-by-step explanation:
21/48 reduced to it's lowest term is 7/16 and solving option b... 7/12 ×3/4 3 would divide 12 to give 4 and multiply what you have left which is 7/4 ×1/4 would be equal to 7/16

create a polynomial in the form ax^3+bx^2+cx=0 that has solutions of x=0,x=-5 and x=11, where a=3
3x^3-18x^2-165x=0
Since we are given the solutions, we can rewrite them.
x=-5 is (x+5)
x=11 is (x-11)
x=0 is just x
Now we can write our equation:
3x(x+5)(x-11)=0
*3 comes from the a being 3
Now we multiply, I’d recommend starting by using FOIL on the last two first and getting;
3x(x^2-6x-55)=0
Then distribute the 3x:
3x^3-18x^2-165x=0
Without graphing, find the slope of the line that goes through (-3, -2) and (-1, -5). *
-3/2
We can find slope using the equation (y2-y1)/(x2-x1). Substitute your values in for the xs and ys.
(-5 - (-2))/(-1 - (-3))
-3/2

D. X-2
Write an inequality relating NM and NL-
NM < NL
NM<_ NL
NM > NL
NM>_ NL
Answer:
NM > LN
Step-by-step explanation:
Here, we want to write an inequality
we should beat it in mind that, the greater the angle that a side of a triangle faces, the greater its length will be relatively
as we can see, the side NM faces the greater angle of 83, relative to the side LN that faces the angle of 56;
So we can conclude that;
NM > LN
Answer:
NM > LN

Graph the relation. Is the relation a function? Why or why not?
{(-5, 6), (-2, 3), (3, 2), (6, 4)}
Yes; there is only one domain value for each range value.
Yes; there is only one range value for each domain value.
No; a domain value has two range values.
No; a range value has two domain values.
Answer:
Yes; there is only one range value for each domain value.
Step-by-step explanation:
For a relation to be a function, every input, x-value, needs to have a unique output, y-value. This means that one x-value cannot have multiple y-values. So, in a function x-values will never repeat. Since x-values do not repeat in this relation, it is a function.

A website received 2500 registered members in July. And the number of registered members in August decreased to 2245. What was the percentage decrease in the number of registered members?
Number of registrations a website received during July = 2500
Number of registrations a website received during August = 2245
Number by which the registrations decreased :
[tex] =\tt 2500 - 2245[/tex]
[tex] =\tt 255[/tex]
Thus, the registrations decreased by 255.
Let x be the perrcentage of decrease.
Which means :
[tex] =\tt 255 = \frac{x}{100} \: of \: 2500[/tex]
[tex] = \tt255 = \frac{x \times 2500}{100} [/tex]
[tex] =\tt 255 = \frac{2500x}{100} [/tex]
[tex] = \tt255 \times 100 = 2500x[/tex]
[tex] = \tt25500 = 2500x[/tex]
[tex] =\tt \frac{25000}{2500} = x[/tex]
[tex]\color{plum} =\tt \bold{10.2\%}[/tex]
▪︎Thus, the percentage of decrease in the number of registered members = 10.2%

PLEASE HELP!! view attachment!!
SUPER EASY
just. determine if function or not
Ok so basically if an input (x) has more than one output (y) it is NOT a function. One output having more than one input is okay though.
So G) is a function, bc for every x there is just 1 y
H) is not a function
I) is not a function either
Then the 6 below ( i can't read their numbers so they're just gonna be 1-6, top 3 from left to right then the bottom three from left to right)
1. function
2. not a function
3. function
4. function
5. not a function
6. not a function
i might be wrong, but i hope this helps!
Answer:
G-Function, H-Not a function, I-Not a Function
Step-by-step explanation:
G is the only one that doesn't repeat its x values

PA HELP plssssssss
Answer:
50y + 75x ≥ 1000 ;
50(15) ≥ 750;
x ≥ 4
y ≥ 15
Step-by-step explanation:
Given that :
Number of stickers sold = y
Cost of sticker = 50
Cost of bag tag = 75
Number of bag tags sold = x
Total worth of items sold ≥ 1000
1)
50y + 75x ≥ 1000
2.)
To make atleast 15 stickers
y ≥ 15
Atleast 15 stickers :
50(15) ≥ 750
3.)
A possible solution :
50(15) + 75(x) ≥ 1000
750 + 75x ≥ 1000
75x ≥ 250
x ≥ 3.33
x ≥ 4
y ≥ 15
