Step-by-step explanation:

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:

The answer is option A

y=-4x+2

Answer:

A y = -4x + 2

Step-by-step explanation:

1) x, y = -2, 10

y = -4x + 2

y = -4 . -2 + 2

y = 8 + 2

y = 10

2) x, y = 0, 2

y = -4x + 2

y = -4 . 0 + 2

y = 2

3) x, y = 1, -2

y = -4x + 2

y = -4 . 1 + 2

y = -4 + 2

y = -2

4) x, y = 3, -10

y = -4x + 2

y = -4 . 3 + 2

y = -12 + 2

y = 10

Answer:

Y=-128

Step-by-step explanation:

Y=-200-6(-12)

Y=-200+72

+200

200+y=72

-200

Y=-128

Step-by-step explanation:

The chances of the first student walking to school is 7/30.

Without replacement, there are 29 students left. Hence the chance of the second student walking to school is 6/29 of the original 7/30 chance.

[tex](\frac{7}{30} )(\frac{6}{29} )=\frac{7}{145}[/tex]

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:

-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.

4 x -5 = -20  

ab x ab = a^2 b^2

As a full sum.

4ab * -5ab = -20a^2 b^2

Step-by-step explanation:

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:

942.5 in^3

Step-by-step explanation:

alright so to find how much space they occupy you just gotta multiply length × width × height. 6.5×14.5×5 is 471.25 u take that and multiply by 2

471.25×2 since there's two boxes. There's your answer 942.5 in^3

Answer:

I think the answer is 942.5 in^3. so C

Step-by-step explanation:

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 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.

Change in weight

[tex] = 1 \frac{3}{4} - \frac{1}{4} [/tex]

[tex] = \frac{7}{4} - \frac{1}{4} [/tex]

[tex] = \frac{7 - 1}{4} [/tex]

[tex] = \frac{6}{4} [/tex]

[tex] = \frac{3}{2} [/tex]

Rate of weight change

[tex] = \frac{3}{2} \div \frac{1}{4} [/tex]

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.

Answer:

V=250cm^3

SA=326cm

Step-by-step explanation:

V= 6x8x5=240

4x5=20 divided by 2=10

240+10=250cm^3

SA= 6x8=48x2=96

6x5=30x2=60

5x8=40x2=80

96+60+80=236

4x5=20

8x5=20

5x5=25x2=50

236+20+20+50=326cm

Hope this helped you :D

Answer:

1/8

Step-by-step explanation:

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.
