A researcher needs 25 mL or 45%
base Solution for a certain
expiriment, but she has only 15%
Solution and 65% Solution. How
many mL of the 15% and the
65% Solutions should she mix to
get what She needs?
Answer:
10 mL of 15% solution
15 mL of 65% solution
Step-by-step explanation:
If x is the volume of 15% solution, and y is the volume of 65% solution, then:
x + y = 25
0.15 x + 0.65 y = 0.45 (25)
Solve with substitution:
0.15 x + 0.65 (25 − x) = 0.45 (25)
0.15 x + 16.25 − 0.65 x = 11.25
0.50 x = 5
x = 10
y = 15

7. Melissa bought 8 yards of string to make bracelets. She wants to cut the string in equal pieces that is 1/2 yard
long. How many pieces of strings with Melissa have?
A 4
B 16
C 40
D 50
Please answer this it’s for a test and I suck in math I don’t even know how I’m in pre ap
Step-by-step explanation: To find this answer, you want to divide the amount of yards in half. This is the case since each string is 1/2. So as a result, each yard of whole string will produce 2 strings. To find your final answer, multiply 2 strings by 8 yards.

i rlly need help im stuck can someone help me out. What the total price?
how do you simplify this?
Answer:
tan x
Step-by-step explanation:
(tan-x)[sec(pi/2)-x] (sin-x)
We know that tan (-x) = - tan (x) and sin (-x) = - sin (x)
-(tanx)[sec(pi/2)-x] -(sinx)
(tanx)[sec(pi/2)-x] (sinx)
Using the identity sec = 1/ cos
sec ( pi/2 -x) =1/cos ( pi /2 -x)
We know that cos (s-t)=cos (s) cos(t) + sin (s) sin (t)
1/ ( cos pi/2 cos x + sin pi/2 sin x) = 1/(0 cos x - 1 sinx) = 1 / sinx
Replacing into the equation
(tanx)[1/ sinx] (sinx)
tan x
In 2016, the cost of 2 ounces of pure gold was $2,640. Complete the double number line to show the cost for 1, 3, and 4 ounces of gold.
Answer:
1 would be 1320
3 would be 3960
4 would be 5280
Step-by-step explanation:
The cost of 1, 3 and 4 ounces of gold in 2016 was $1,320, $3,960 and $5,280 respectively.
Cost of 2 ounces of gold in 2016 = $2,640
Cost of 1 ounce of gold in 2016 = Cost of 2 ounces of gold in 2016 ÷ 2
= $2,640 ÷ 2
= $1,320
Cost of 3 ounces of gold in 2016 = Cost of 1 ounce of gold in 2016 × 3
= $1,320 × 3
= $3,960
Cost of 4 ounces of gold in 2016 = Cost of 1 ounce of gold in 2016 × 4
= $1320 × 4
= $5,280
Therefore, the cost of 1, 3 and 4 ounces of gold in 2016 are $1,320, $3,960 and $5,280 respectively.

A purse contains a collection of quarters, dimes, nickels, and pennies. The average value of the coins in the purse is 17 cents. If a penny is removed from the purse, the average value of the coins becomes 18 cents. How many nickels are in the purse?
Answer:
There are total of 17 coins in the purse
Step-by-step explanation:
Let x represent the no of coins in the purse
Let y represent the total amount
y/x = 0.17
y = 0.17*x............................(i)
y-0.01 / x-1 = 0.18
y - 0.01 = 0.18x -0.18........(ii)
We substitute y = 0.17 x into the second equation:
0.17x - 0.01 = 0.18x - 0.18
0.17 = 0.01x
x = 17
Hence, there are total of 17 coins in the purse

Write a system of linear equations that has (-4, 8) as the solution. Once you have made your system of equations, solve it algebraically to show that you do indeed get the solution (-4, 8).
Answer:
See below
Step-by-step explanation:
(-4, 8) has to be the solution.
1st equation: -4x+8y = 1
2nd equation: 8x - 4y = 1
These should work. Do the matrix-substitution combo method to see:
-4 8 1
.8 -4 -1
Reduce and and matrix-substitution combo:
1 0 -4
0 1 8
The reduced eckerd form of the matrix shows that the solutions are (-4, 8)
Therefore it -4x + 8u = 1 and 8x - 4y = 1 are the two equations for the system.

Composite functions
g(d) = 2d - 5
h(d) = -4d +3
Find (hºg)(d)
Answer:
[tex](h\circ g)(d)=-8d +23[/tex]
Step-by-step explanation:
Composite Function
Given g(d) and h(d) real functions, the composite function named (hog)(d) is defined as:
[tex](h\circ g)(d)=h(g(x))[/tex]
For practical purposes, it can be found by substituting g into h.
The functions g and h are given as:
[tex]g(d) = 2d - 5[/tex]
[tex]h(d) = -4d +3[/tex]
Substituting g into h:
[tex](h\circ g)(d)=-4(2d - 5) +3[/tex]
Operating:
[tex](h\circ g)(d)=-8d +20 +3[/tex]
[tex]\boxed{(h\circ g)(d)=-8d +23}[/tex]
17.) You want to purchase 4 board games that are $15 each. There is a 6% sales tax. What is the
total amount of your purchase?
Answer:
$63.60
Step-by-step explanation:
4 board games are $15 each, multiply 4*15 = 60.
There is a 6% sales tax, so it is 6% extra. To calculate 6% as a decimal, divide it by 100, so 6/100 = 0.06. Now that it is 0.06 extra, you add 0.06 to 1.00 because 1.00 is the 100% of the price (the $60). So now it is 1.06 of the price. Multiply 60 * 1.06 and you get $63.60
Answer:
60.36 cents
Step-by-step explanation:
you have to times 60 by .6 then you get 36 and that is how much taxes cost.

Answer:
no; 2 has many factors besides 2
Step-by-step explanation:
The zero product rule says the only way a product may have a value of zero is if one or more factors is zero. That is why one of the factors of ...
(x^2 +a)(x^2 +b) = 0
must have a value of 0.
__
The same cannot be said of 2. We might have (1/2)(4) = 2, for instance, in which neither factor is 2. That a product is 2 is not a requirement that one of the factors be 2.
