Answer:

For a trapezium of height H, parallel side 1 X, and parallel side 2 Y, the area is:

A = (1/2)*H*(X + Y)

with this we can complete the table.

a)

Here we know:

X = 7cm

Y = 11cm

H = 6cm

Then: A = (1/2)*6cm*(7cm + 11cm) = 54 cm^2

b)

Here we know:

X = 8 m

Y = 10 m

A = 126 m^2

Then:

126 m^2 = 0.5*H*(8m + 10m)

126 m^2 = H*9m

126 m^2/9m = H = 14m

Then the height of this trapezoid is 14m

c)

Here we know:

X = 5mm

H = 8mm

A = 72 mm^2

Then:

72 mm^2 = 0.5*8mm*(5mm + Y)

72 mm^2 = 4mm*(5mm + Y)

72mm^2/4mm = 5mm + Y

18 mm = 5mm + Y

18mm - 5mm = Y

13 mm = Y

Then the parallel side 2 is 13 mm long.

Answer:

The multiples of a whole number are found by taking the product of any counting number and that whole number. For example, to find the multiples of 3, multiply 3 by 1, 3 by 2, 3 by 3, and so on. To find the multiples of 5, multiply 5 by 1, 5 by 2, 5 by 3, and so on.

Step-by-step explanation:

5 × 1 = 5

5 × 2 = 10

5 × 3 = 15

5 × 4 = 20

2 × 1 = 2

2 × 2 = 4

2 × 3 = 6

2 × 4 = 8

2 × 5 = 10 and so on

Answer:

It does not matter whether you multiply the radicands or simplify each radical first. You multiply radical expressions that contain variables in the same manner. As long as the roots of the radical expressions are the same, you can use the Product Raised to a Power Rule to multiply and simplify.

Answer:   (-16, -14)

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

Explanation:

To get that result, you multiply each coordinate by the scale factor 2

We have

So that's why (-8,-7) moves to (-16, -14)

This trick only works if the origin is the center of dilation.

Answer:

8.80

Step-by-step explanation:

The hundredths place is occupied by the 9.

First, drop the last 8.

8.79

Since the digit to the right of the dropped 9 is an 8, you round up.

8.79 becomes 8.80

Answer: 112.5 m^2

Step-by-step explanation:

Area of rectangle = lw

l = 7.5

w = 15

7.5 * 15 = 112.5

Answer:

112.5 Meters

Step-by-step explanation:

The Area is length x width.

7 1/2 meters x 15 meters is equal to 112.5 meters to therefore the Area of that rectangle is 112.5 meters.

Explanation:

Let y be the measure of angle ABC.

We can see that y = 4x+17 because the two angles (y and 4x+17) are vertical angles. Vertical angles are always congruent.

-------------

From here, focus entirely on the interior angles of triangle ABC.

Recall that for any triangle, the interior angles always add to 180

A+B+C = 180

(x+23)+(y)+(80) = 180 ..... plug in the given angle measures

(x+23)+(4x+17)+(80) = 180 .... replace y with 4x+17

5x+120 = 180 ..... combine like terms

5x = 180-120 ..... subtract 120 from both sides

5x = 60

x = 60/5 ..... divide both sides by 5

x = 12

Now use that x value to find the following:

--------------------------

In short we have this summary of values we found:

Answer:Selling Price = $115

Step-by-step explanation:

Selling price = Cost price + Profit

Cost price = $100

Profit = 15% = 15%  x 100 = $15

Selling Price = $100 + $15= $115

OR

Selling Price  =  Cost price + Profit

Selling Price =$100 + (15% of $100)

Selling Price = $100+ $15

= $115.

Answer: substitution

Step-by-step explanation:

Substitute 3 in for x for all equations.

3(3)+4 = 13

8(3)-1 = 23

3(3)+4 =13

Add all of the sides together to find the perimeter

13+23+13 =49

Easy :)

Quotient means dividing something by something else.

So,

Quotient of x and 3 is x3

If the question says Quotient of x and 3 minus 8 then you can write it as x3-8
