George bought 7 quarts of cleaning fluid: x quarts at $3.00 per quart & y quarts at $2.00 per quart. Find x & y if the total cost was $16.00. First type the equation for the total cost. Now, type the equation for the cost of each

Answers

Answer:

3x + 2y = 16

x = 2 , y = 5

Step-by-step explanation:

Given that George bought x quarts at $3.00 per quart & y quarts at $2.00 per quart and he bought 7 quarts for $16.00

Considering the total cost

3x + 2y = 16

For the cost of each

x + y = 7

solving the 2 equations simultaneously be substitution

x = 7 - y

3(7 - y) + 2y = 16

21 - 3y + 2y = 16

-3y + 2y = 16 - 21

-y = - 5

Divide both sides by -1

y = 5

x = 7 -y

x = 7 - 5

= 2

Quadratic functions g(x) and h(x) are graphed on the same coordinate grid. The vertex of the graph of h(x) is 24 units to the right of the vertex of the graph of g(x). Which pair of functions could have been used to create the graphs of g(x) and h(x)?

h(x)=x2−24 and g(x)=x2

h(x)=x2+24 and g(x)=x2

h(x)=(x−24)2 and g(x)=x2

h(x)=(x+24)2 and g(x)=x2

Answers

Answer:

The correct pair of functions is the third one:  h(x)=(x−24)^2 and g(x)=x2

Step-by-step explanation:

Example:  If we have q(x) = x^2 and its graph, moving the vertex of this graph 24 units to the right results in r(x) = (x - 24)^2.

The correct pair of functions is the third one:  h(x)=(x−24)^2 and g(x)=x2

Note:  the fourth pair is incorrect, because the " + " sign moves the graph of x^2 24 units to the left.

Store A sells a box of 8 pencils for $0.89. Store B sells a box of 12 pencils for $1.25. Which store sells the better deal? Tell the unit rate for each store (rounding to nearest cent)

Answers

Answer:

Should be store B :) The unit rate for store A (rounded) is 0.11 and the rounded unit rate for store B is 0.10

Step-by-step explanation:

Answer:

Store B has the better deal

Unit rate:

Store A = $0.11

Store B = $0.10

Step-by-step explanation:

Store A :

8pencils = $0.89

1 pencil = $0.89/8 = $0.111

Store B:

12pencils = $1.25

1 pencil = $1.25/12 = $0.104

Store B sells 1 pencil at $0.104 and store A at $0.111

Therefore Store B sells the better deal.

Lamar needs to buy some pencils. Brand A has a pack of 18 pencils for 2.36 . Brand B has a pack of pencils 24 for 4.09 Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent.

Answers

Answer:

The unit price of brant A and brand B is 0.1311 and 0.1704 and brand A would be better

Step-by-step explanation:

The computation of the unit price for each brand is shown below:

For brand A, the unit price is

= 2.36 ÷ 18 pencils

= 0.1311

For Brand b, the unit price is

= 4.09 ÷ 24

= 0.1704

So here as we can see that brand A would be better as it has less cost as compared with brand B

A carpenter is assigned the job of expanding a rectangular deck where the length is three times the width. The width of the deck is to be expanded by 8 feet and the length is to be expanded by the new width. If the area of the new rectangular deck is 240 ft larger than the area of the original deck, find the dimensions of the original deck.

Answers

Let Xo = original length of the deck
Yo = original width of deck
Therefore:
Yo = (1/6)Xo
The original deck area is:
Ao = XoYo
Ao = Xo(1/6)Xo = (1/6)Xo2
The length of the new deck is 4ft longer than the original deck, or XN = Xo + 4, and the width is 2ft longer than the original, or YN = Yo + 2, and the new area of the deck is 56ft2 than the original area, or AN = Ao + 56.
Therefore: AN = XNYN
Ao + 56 = (Xo + 4)(Yo + 2)
(1/6)Xo2 + 56 = (Xo + 4)(1/6Xo + 2)
(1/6)Xo2 + 56 = (1/6)Xo2 + 2Xo + (4/6)Xo +8
56 = 2Xo + (2/3)Xo +8
56 - 8 = (2 + 2/3)Xo
48 = (6/3 + 2/3)Xo
48 = (8/3)Xo
48(3/8) = Xo
Xo = 18ft
Yo = (1/6)(18)
Yo = 3ft
Check: Ao = XoYo = (18)(3) = 54ft2
XN = Xo + 4 = 18 + 4 = 22ft
YN = Yo + 2 = 3 + 2 = 5ft
AN = (22)(5) = 110ft2
Ao + 56 = AN
54 + 56 = 110
110 = 110 check------->ANSWER: original length, Xo = 18ft
original width, Yo = 3ft

The volume of the cylinder is 84 pi inches squared What can be concluded about the volume of the cone? Check all that apply.
The volume of the cone is One-third the volume of the cylinder.
The volume of the cylinder is 2 times the volume of the cone.
The volume of the cone is less than the volume of the cylinder.
The expression 84 pi over 3 finds the volume of the cone.
The expression 84 pi over 2 finds the volume of the cone.

Answers

The correct statements about the volume of the cone are:

- The volume of the cone is One-third the volume of the cylinder.

- The expression 84 pi over 3 finds the volume of the cone.

- The volume of the cone is less than the volume of the cylinder.

What is the volume of cylinder?

[tex]V=\pi\times r^2\times h[/tex]

where 'r' is the radius of the base of the cylinder and 'h' is height of the cylinder

What is the volume of the cone?[tex]V=\pi\times r^2\times \frac{h}{3}[/tex]

where 'r' is the radius of the base of the cone and 'h' is height of the cone

For given example,

The volume of the cylinder is 84 pi inches cubed.

Let [tex]V_1[/tex] represents the volume of the cylinder.

[tex]V_1=84~~cu.in.[/tex]

Using the formula of the volume of the cylinder,

[tex]V_1=\pi\times r^2\times h[/tex]

where 'r' is the radius of the base of the cylinder and 'h' is height of the cylinder

Let [tex]V_2[/tex] be the volume of the cone.

Assume that the base radius 'r' and height 'h' of the cone and the cylinder are equal.

Using the formula of the volume of the cone,

[tex]\Rightarrow V_2=\pi\times r^2\times \frac{h}{3}\\\\\Rightarrow V_2=\frac{1}{3}\times( \pi\times r^2\times h) \\\\\Rightarrow V_2=\frac{1}{3}\times V_1[/tex]

This means, the volume of the cone is One-third the volume of the cylinder.

[tex]\Rightarrow V2=\frac{1}{3}\times 84[/tex]

This means, the expression 84 pi over 3 finds the volume of the cone.

[tex]\Rightarrow V_2=28~~cu.in.\pi \\\\\Rightarrow V_2 < V_1[/tex]

This means, the volume of the cone is less than the volume of the cylinder.

Therefore, the correct statements about the volume of the cone are:

- The volume of the cone is One-third the volume of the cylinder.

- The expression 84 pi over 3 finds the volume of the cone.

- The volume of the cone is less than the volume of the cylinder.
