Answer 1

Answer:

x=21/5, also known as 4.2

Step-by-step explanation:

5x:9 = 7:3

Solve it like a proportion and get any of these answers

5x/9 = 7/3

cross product property

3(5x) = 63

15x = 63

x = 63/15 = 21/5 in fraction form = 4.2 in decimal form

Edwin bought 3 cds and 7 dvd for $80 Jessica bought 6cds and 3 dvds for $63.75 which system of equation could be used to determine how much one cd and one dvd cost

Answers

Answer:

The system of equations 3x + 7y = 80 and 6x + 3y = 63.75 can be used to determine the cost of one CD and one DVD.

Step-by-step explanation:

Given that:

Cost of 3 CDs and 7 DVDs = $80

Cost of 6 CDs and 3 DVDs = $63.75

Let,

x be the cost of one CD

y be the cost of one DVD

According to given statement;

3x + 7y = 80

6x + 3y = 63.75

Hence,

The system of equations 3x + 7y = 80 and 6x + 3y = 63.75 can be used to determine the cost of one CD and one DVD.

The volume of a golf ball is approximately 4in.3 what is the diameter round you answer to the nearest whole number

A 4 in
B 6 in
C 1 in
D 2 in

Answers

Answer:

D. 2 inches.

Step-by-step explanation:

Given the following data;

Volume of golf (sphere) = 4 in³

A golf ball is spherical in shape. Thus, to find its volume we would use the formula for the volume of a sphere.

[tex] Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3} [/tex]

Substituting into the equation, we have;

[tex] 4 = \frac {4}{3} * 3.142* r^{3} [/tex]

Cross-multiplying, we have;

[tex] 12 = 4 * 3.142* r^{3} [/tex]

[tex] 12 = 12.568 * r^{3} [/tex]

[tex] r^{3} = \frac {12.568}{12} [/tex]

[tex] r^{3} = 1.0473 [/tex]

Taking the cube root of both sides, we have;

Radius, r = 1.016 inches.

To find the diameter;

Diameter = radius * 2

Diameter = 1.016 * 2

Diameter = 2.03 ≈ 2 inches.

the answer is 2.

Composite figure composed of a a right triangle with a base of 3 mm and a height of 4 mm, and two rectangles, one with side lengths of 3mm and 4mm, the other with side lengths of 1 mm and 6 mm.

Answers

Answer:

18 mm²

Step-by-step explanation:

Firstly, I do not think the person above me has the correct answer.

Okay, so I am not very good at explaining things but I will try. When finding the area of a composite figure, you add Area A + Area B.

So for this equation, figure one has a length of 4mm and a width of 3mm. Remember when we are finding the area of a shape, we multiply Length times Width. So, figure one has an area of twelve. The Same applies to figure two. Figure two has a length of 1mm and a width of 6mm, we multiply one by six and get six. Now we add the area of the twelve and six and we get 18mm²

I understand that my explaining skills suck, so I will show it in an easier way

Area A = 4mm x 3mm

Area A = 12mm

Area B = 1mm x 6mm

Area B = 6mm

Area A + Area B = Total Area

12mm + 6mm = 18mm²

So, 18mm² will be your answer.

I hope this helps.

Sorry if it isn't helpful or correct.

The total area of the composed figure with right triangle and two rectangles is 24 square millimeters.

What is Area of Rectangle?

The area of Rectangle is length times of width.

Composite figure has a right triangle and two rectangles.

right triangle with a base of 3 mm and a height of 4 mm

Area of triangle = 1/2×4×3

=6 square millimeter

Area of first rectangle with side lengths of 3mm and 4mm

Area of first rectangle = 3 × 4

= 12 square millimeter

Area of second rectangle with side lengths of 1mm and 6 mm

Area of second rectangle =1×6

=6 square millimeter

Total area is 6+12+6 which 24 square millimeters.

Hence, the total area of the composed figure with right triangle and two rectangles is 24 square millimeters.

Kate has 48 softballs. She wants to divide them evenly among b softball bags. Which expression represents how many softballs she should put into each bag?

Answers

Answer:

Softballs = (48/b)

Step-by-step explanation:

Given that,

Total number of softballs = 48

She wants to divide them evenly among b softball bags.

We need to find an expression that represents how many softballs she should put into each bag.

As it is dividing among b softball, it means we divide 48 and b. So,

[tex]s=\dfrac{48}{b}[/tex]

Hence, the required expression is (48/b).

To find:

The error in his solution.

Solution:

We have,

[tex]144x^2-100[/tex]

It can be written as

[tex]=12^2x^2-10^2[/tex]

[tex]=(12x)^2-10^2[/tex]

[tex]=(12x+10)(12x-10)[/tex]             [tex][\because a^2-b^2=(a+b)(a-b)][/tex]

Taking out common factors from each parenthesis.

[tex]=2(6x+5)2(6x-5)[/tex]

So, Jeremy was incorrect because the common factor is [tex]2\times 2=4[/tex] instead of 2.

Answers

9514 1404 393

Answer:

  $1571

Step-by-step explanation:

If we assume that y is profit in dollars, the maximum value of y is revealed by a graph to be ...

  ymax = $1571

The maximum profit the company can make is $1571 at a selling price of $45 each.

_____

The function can be written in vertex form as ...

  y = -(x^2 -90x) -454

  y = -(x^2 -90x +45^2) -454 +45^2

  y = -(x -45)^2 +1571

Because the leading coefficient is negative, we know this vertex represents a maximum. (x, y) = (45, 1571) at the vertex. Maximum profit is $1571.
