Answers

Answer:

A + (100 +4.5A) = 1675A ≈ 286.4 square feet

Step-by-step explanation:

The problem statement tells us that the area of the sandbox and playground together is 1675 square feet. Using A as the area of the sandbox section, the playground section is said to be (100 +4.5A). Then the total area is ...

  A + (100 +4.5A) = 1675 . . . . . . an equation to determine A

  5.5A = 1575 . . . . . . . . . . . . . . . subtract 100, collect terms

  A = 1575/5.5 = 286 4/11 . . . . . divide by 5.5

The area of the sandbox section is about 286.4 square feet.

You have 59 total coins in a jar on your nightstand at home. The total amount of money is $12.05. You only have quarters and dimes. How many of each type of coin do you have? (hint - use a different method to write and solve the system).​

Answers

9514 1404 393

Answer:

41 quarters18 dimes

Step-by-step explanation:

When there are two contributors to the mix, it usually works well to let a variable represent the quantity of the larger contributor. Here, that larger contributor is the quarter.

Let q represent the number of quarters. Then 59-q is the number of dimes. The value of the coins, in cents, is ...

  25q +10(59 -q) = 1205

  15q +590 = 1205 . . . . . . . . eliminate parentheses, collect terms

  15q = 615 . . . . . . . . . . . subtract 590

  q = 41 . . . . . . . . . . divide by 15

  59-q = 59 -41 = 18 . . . . . number of dimes

You have 41 quarters and 18 dimes.

14. A right cone has a height of 14 in and a base diameter of 17 in.
a Sketch and label a diagram of the cone
b. Determine the area of the lateral surface of the cone, to the nearest square inch​

Answers

Given:

The height of a right cone = 14 in

Base diameter = 17 in

To find:

The diagram of the cone and its lateral surface area.

Solution:

(a)

The diagram of a right cone with height 14 in and base diameter of 17 in is shown below.

Diagram is not to scale.

(b)

We know that lateral surface of the cone is

[tex]A=\pi rl[/tex]

[tex]A=\pi r\sqrt{r^2+h^2}[/tex]              ...(i)

Where, r is the base radius, h is vertical height and l is the slant height of the cone.

Base radius of the cone = [tex]\dfrac{\text{Base diameter}}{2}[/tex]

[tex]r=\dfrac{17}{2}[/tex]

[tex]r=8.5[/tex]

Now,

Putting r=8.5, h=14 and π=3.14 in (i), we get

[tex]A=(3.14)(8.5)\sqrt{(8.5)^2+(14)^2}[/tex]

[tex]A=26.69\sqrt{72.25+196}[/tex]

[tex]A=26.69\sqrt{268.25}[/tex]

[tex]A=437.1379[/tex]

[tex]A\approx 437[/tex]

Therefore, the lateral surface area of the cone is 437 sq. inches.

Find the area of the semicircle. 10

Answers

Exact Area = 25pi   square units

Approximate Area = 78.5  square units

The approximate value is found using pi = 3.14

====================================================

Explanation:

I think you meant to say "quarter circle" instead of "semicircle".

The area of a full circle with radius r = 10 is

A = pi*r^2

A = pi*10^2

A = pi*100

A = 100pi

But we only want one quarter of this. So we divide the full area by 4

(100pi)/4 = (100/4)pi = 25pi

The exact area in terms of pi is 25pi square units

If we used the approximation pi = 3.14, then we can say 25*pi = 25*3.14 = 78.5 is the approximate area

To get a better approximation, use more decimal digits in pi.

(x + 7)^2 – 11 = 0
lesser =
greater =

Answers

Answer:

Lesser = -[tex]\sqrt{11}[/tex] - 7 = -10.317

Greater = +[tex]\sqrt{11}[/tex] - 7 = -3.683

Step-by-step explanation:

I am assuming you are asking for the lesser x solution and greater x solution.

(x + 7)^2 – 11 = 0

(x + 7)^2 = 11

x+7 = ±[tex]\sqrt{11}[/tex]

x = ±[tex]\sqrt{11}[/tex] - 7

Lesser = -[tex]\sqrt{11}[/tex] - 7 = -10.317

Greater = +[tex]\sqrt{11}[/tex] - 7 = -3.683

lesser= -14
