Answer:

75 square feet

Step-by-step explanation:

If you put 3 tables together thats length is 5 square feet you add up the 3 5 feet which is 15 and you multiply that by the 5 on the end and you get 15.

                                                    15 feet

                5 feet                                5 feet                             5 feet

5ft  |                                  15 x 5 = 75 square feet                                                 |

     |______________________________________________-_________|

Answer:

75 square feet

Step-by-step explanation:

Because if each side of  the table is  5 feet all you have to do is multiply 5 by 5 and get 25.  Then, since their are 3 table just multiply 25 by 3 to get 75.

Answer: 3.84 m

Step-by-step explanation: The biggest clue here is that the scale factor is 1:12.

1:12=32:[tex]x[/tex]

To find [tex]x[/tex], multiply 32 by 12. 32x12 is 384. You can't say the answer is 384, however, since the label for the actual water tower says "m" for meters instead of "cm" like for the model. 384 cm is equal to 3.84 m.

Hope this helped! ;)

Answer:

[tex]x = 1[/tex]

[tex]y=z[/tex]

Step-by-step explanation:

[tex]xy = z\\zx = y[/tex]

Substitute [tex]z[/tex] and [tex]y[/tex] back into the equations.

[tex]xyx =y\\x^2y=y\\x^2=1\\x=\sqrt{1} = 1[/tex]

[tex]z(1) = y\\z=y[/tex]

We cannot find [tex]z[/tex] and [tex]y[/tex] as we don't have enough information.

Answer:

$21,700

Step-by-step explanation:

$115,000 - 98,000

$115,000 - 98,000 = 17000

Credit Card Balance = Money owed

17000 - 2300

17000 - 2300 = 14700

Cars worth = +

14700 + 5800

14700 + 5800 = 20500

Bank Acc = +

20500 + 900

20500 + 900 = 21400

Gift Cards = +

21400 + 300 = 21700

The variable x represent the width of the border. Option A is correct.

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters is the unit of the area.

The total area of the place mat to include the border is represented by the expression;

(4+2x)(6+2x).

Total area = Surface area+inner area

Hence, option A is correct. The variable x represent the width of the border.

Answer:

-20a^2b^2

Step-by-step explanation:

4ab * -5ab  we see the qu asks to multiply a negative with a positive

so we automatically know it will be a negative. and we know monomials become squared.

The area of a trapezium ABCD in which AB || CD, AB = 14 cm, CD = 8 cm. Given

that AB = 23 cm, CD = 7 cm and AD = 17 cm.

Answer:

The area of a trapezium ABCD given the measure of sides is determined by the following equation: A = 1/2 (AD + BC) * h, where h is the height of the trapezium. Using the given information, the area can be calculated as A = 1/2 * (14 + 8) * (23/2) = 200 cm^2.

So the total she pays is 30 dollars (20+5+5). The puzzle amount was 27.83. Subtract 27.83 from 30 dollars to get her change.

$2.17

Therefore, you could use a 2-dollar bill (or 2 1-dollar bills), a dime (10 cents), 1 nickel (5 cents), and two pennies (1 cent each). This will amount to the total change.

Answer:

160

Step-by-step explanation:

5x-10+12x=16x

17x-16x=10

x= 10

exterior angle at C = 16x= 16×10 = 160°

Answer:

exterior ∠C = 160

Step-by-step explanation:

Exterior angle property: Exterior angle equals the sum of opposite interior angles.

∠A + ∠B = exterior ∠C

5x - 10 + 12x  = 16x  {Combine like terms}

 17x - 10 = 16x         {Add 10 to both sides}

        17x = 16x+ 10         {Subtract 16x form both sides}

17x - 16x = 10

         x = 10

exterior ∠C  = 16x = 16 * 10 = 160

The required ratio of the circle to squares in the diagram is 1:1.

Given that,
To determine the ratio of the circles to squares in the diagram.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Example there are 4 liters of water in 8 liters of milk = 4 / 8 = 1 / 2 =  1 : 2.

Fraction is defined as the number of compositions that constitute the Whole. Fraction is represented as a / b where a = numerator and b denominator.

Here,
In the given diagram there is three circles and 3 square.
The ratio of the circles to square  = 3 : 3 = 1

Thus, the required ratio of the circle to squares in the diagram is 1:1.

Answer:

Step-by-step explanation:

First let's find the area of the middle rectangle.

We know the width of this rectangle is 6 and the length is 8 so we will multiply these two numbers.

6 × 8 = 48

Now let's find the area of the triangles

The formula is ((length × width) ÷ 2)

The width is 3, as it is not part of the rectangle, and the length is 8

And there are two triangles so we will do this twice

((8 × 3) ÷ 2) = 12

((8 × 3) ÷ 2) = 12

Now add up all of the areas

48 + 12 + 12 = 72

So 72 is our final answer
