You need 520 mL of a 15% alcohol solution. On hand, you have a 65% alcohol mixture. How much of the 65% alcohol mixture and pure water will you need to obtain the desired solution?

You will need _____ mL of pure water and _____ mL of the 65% solution.

Answers

Answer 1

Answer:

400 ml, 120 ml

Step-by-step explanation:

Alcohol content of 15% solution:

0.15*520 = 78 ml

Volume of 65% solution containing 78 ml of alcohol:

78/0.65 = 120 ml

Required water volume to obtain 15% solution:

520 - 120 = 400 ml

Sonia works at a bakery. The function f(x) represents the amount of money Sonia earns per loaf, where x is the number of loaves she makes. The function g(x) represents the number of bread loaves Sonia bakes per hour, where x is the number of hours she works. Show all work to find f(g(x)), and explain what f(g(x)) represents.
f(x) = 8^2 +4
g of x equals the square root of the quantity 2 x cubed

Answers

Answer:

[tex] f(x)=8x^2+4\\ g(x)=\sqrt{2x^3}\\ f(g(x))=8((\sqrt{2x^3})^2)+4\\=16x^3+4\\=4(4x^3+1)[/tex]

The function f(g(x)) will be f(g(x)) = 4(4x³ + 1) where 'x' is the number of hours.

What is a function?

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The functions are given below.

f(x) = 8x² + 4

g(x) = √(2x³)

The function f(g(x)) is calculated as,

f(g(x)) = 8[√(2x³)]² + 4

f(g(x)) = 8[√(2x³)]² + 4

f(g(x)) = 16x³ + 4

f(g(x)) = 4(4x³ + 1)

The function f(g(x)) will be f(g(x)) = 4(4x³ + 1) where 'x' is the number of hours.

Lena's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Lena S4.10 per pound, and type B coffee costs $5.95 per
pound. This month's blend used twice as many pounds of type B coffee as type A, for a total cost of $336.00. How many pounds of type A coffee were used?

Answers

Answer: Just bought 21 pounds of coffee A

Step-by-step explanation:

We know that she consumed twice as many pounds of Type                              B coffee as type A.Then let the total number of cafe feet A=x ; then the                              number of cafe feet B=2x . We also know that the total number of feet cost $336

And the fact that one pound of coffee A costs $ 4.1 ; and one pound of coffee B costs $ 5.95

Then :[tex]\large \boldsymbol {} 2x\cdot 5,95 +x\cdot 4,1 =336 \\\\ 11,9x+4,1x=336 \\\\ 16x=336 \\\\ \boxed{x=21}[/tex]

You bought a package of paper for $3 and some pencils for $2 each at the school store. You paid $15 for everything that you bought. How many pencils did you buy?

Answers

Answer:

6  pencils

Step-by-step explanation:

Total cost = paper * cost of a package + pencils * cost of a pencils

We bought 1 pack of paper at 3 dollars and p pencils at 2 dollars

15  = 1*3 + p*2

15 = 3+2p

Subtract 3 from each side

15-3 = 3+2p-3

12 = 2p

Divide by 2

12/2 = 2p/2

6 = p

The endpoints of AC are A(-8, 9) and C (1, -3). Point B(-2, 1) lies on AC. What
is the ratio AB: BC?
A 1:2
B
1:1
C) 2:1
D) 3:1

Answers

Answer:

c)2:1..................

Answer:

C

Step-by-step explanation:

Find the distance of AB:

Distance formula: [tex]\sqrt{[(-8)-(-2)]^2+(9-1)^2}[/tex]

[tex]\sqrt{(-6)^2+(8)^2}=\sqrt{36+64}=\sqrt{100}=10 units[/tex]

Find the distance of BC:

Distance formula: [tex]\sqrt{[(-2)-1]^2+[1-(-3)]^2}[/tex]

[tex]\sqrt{(-3)^2+4^2}=\sqrt{9+16} =\sqrt{25} =5 units[/tex]

AB=10 units

BC=5 units

AB:BC = 10:5=2:1
