Explanation:

There are several possible properties in each case. We have shown one of them.

a) squares and rectangles have four (4) angles of 90°.

b) squares have sides of equal length; rectangles may not.

c) rhombi and squares have diagonals that bisect each other at right angles

d) rhombi have sides of equal length; parallelograms may not.

e) opposite sides of all parallelograms are equal length.

Answer:

The value of x is 50

The measures of the 3 angles are 50°, 100°, 30°

Step-by-step explanation:

Let us solve the question

∵ The sum of the measures of the angles of a triangle is 180°

∵ The measures of the 3 angles of the given Δ are x°, 2x°, (x - 20)°

→ Add them and equate the sum by 180

∴ x° + 2x° + (x - 20)° = 180°

→ Add the like terms

∵ (x + 2x + x) + (-20) = 180

∴ 4x - 20 = 180

→ Add 20 to both sides

∵ 4x - 20 + 20 = 180 + 20

∴ 4x = 200

→ Divide both sides by 4 to find x

∴ x = 50

∴ The value of x is 50

To find the measures of the 3 angles substitute x by 50 in their expressions

∵ The measure of one angle is x

∴ The measure of the 1st angle is 50°

∵ The measure of the 2nd angle is 2x

∴ The measure of the 2nd angle = 2(50)

∴ The measure of the 2nd angle is 100°

∵ The measure of the 3rd angle is (x - 20)

∴ The measure of the 3rd angle = (50 - 20)

∴ The measure of the 3rd angle is 30°

∴ The measures of the 3 angles are 50°, 100°, 30°

The answer is below

Step-by-step explanation:

A) i)

For Anna initially, she has $0 from making 0 envelopes. After making 400 envelopes she has $20. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (400, 20). Using the equation of a line:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-0=\frac{20-0}{400-0}(x-0)\\\\y=\frac{1}{20} x[/tex]

The table is:

x:   200     400       600     800     1000

y:    10        20          30        40       50

ii)

For Jason initially, he has $0 from making 0 envelopes. For every 250 envelopes he has $10. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (250, 10). Using the equation of a line:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-0=\frac{10-0}{250-0}(x-0)\\\\y=\frac{1}{25} x[/tex]

The table is:

x:   200     400       600     800     1000

Answer:

My answer

Step-by-step explanation:

First you convert it and it is 0.06 m. This is because

Conversion factor: 1 m = 100 cm

1) m = cm / 100

2) m = 6 / 100

3) m = 0.06

Then you do the error interval. Error interval – the range of values (between the upper and lower bounds) in which the precise value could be. Thn you caculate it by when you do this x2 then do <.

Answer:

a = 1, b = - 12

Step-by-step explanation:

we know that x = 3 and x = - 4, so (x - 3) and (x + 4) must be the factors of the equation:

(x - 3)(x + 4)

x^2 + - 3x + 4x - 12

x^2 + x - 12

therefore a = 1 and b = - 12

Step-by-step explanation:

firstly substitute x=3 into [tex]x^{2} +ax+b=0[/tex]

[tex]3^{2} +3a+b=0[/tex]

9+3a+b = 0

          b = -3a-9

secondly substitute x=-4 into [tex]x^{2} +ax+b=0[/tex]

[tex](-4)^{2} +(-4)a+b=0[/tex]

16-4a+b = 0

          b = 4a-16

combine the equations above,

-3a-9 = b = 4a-16

so -3a-9 = 4a-16

     7a = 7

       a = 1

then substitute a = 1 into b = 4a-16 or b = -3a-9 (both are ok)

b = 4(1)-16 = -12     or        b = -3(1)-9 = -12

Answer:

Harry has a score of 30

Step-by-step explanation:

Let us represent their scores as:

Nathan = x

Harry = y

Jack = z

At the end of a football season a coach is adding up everyone's scores

Nathan has scored 11 more than harry

x = y + 11

Harry has scored 10 more then jack.

y = z + 10

z = y - 10

If the total of their scores is 91

x + y+ z = 91

y + 11 + y + y - 10 = 91

3y + 1 = 91

3y = 91 - 1

3y = 90

y = 90/3

y = 30

Since Harry's score is represented as y, Harry has a score of 30

Answer:

  3. ΔBEA ~ ΔBCD by AA

  4. ΔPXY ~ ΔPQR by SSS

Step-by-step explanation:

3. The missing angle in ΔBEA is angle E, which has measure ...

  ∠E = 180° -42° -53° = 85°

So, angle E matches angle C, and the vertical angles match. The two triangles are similar by AA. The corresponding angles are B:B, and E:C, so the similarity statement needs to reflect that: ΔBEA ~ ΔBCD.

__

4. Shortest-to-longest, the side ratios of the two triangles are ...

  12 : 15 : 18 = 4 : 5 : 6

and

  16 : 20 : 24 = 4 : 5 : 6

Side ratios are proportional, so the triangles are similar by SSS. The similarity statement can reflect the same ordering: ΔPXY ~ ΔPQR.

Answer:

Radius = 12

Step-by-step explanation:

For an inscribed circle of a triangle ABC,

GE = GF = GD = radius of the inscribed circle

Therefore, (-3y + 18) = (5y + 2)

-3y + 18 - 5y = 5y + 2 - 5y

-8y + 18 = 2

-8y + 18 - 18 = 2 - 18

-8y = -16

8y = 16

[tex]\frac{8y}{8}=\frac{16}{8}[/tex]

y = 2

Therefore, GE = -3y + 18

                       = -3(2) + 18

                       = -6 + 18

                       = 12

Radius of the inscribed circle = GE = 12 units

The measure of the radius of the inscribed circle is 12 units

From the given diagram, GE = GF

Given the following parameters:

GE = -3y + 18 and:

GF = 5y + 2

Equating both expressions

-3y + 18 = 5y + 2

-3y - 5y = 2 - 18

-8y = -16

y = 16/8

y = 2

The measure of the radius of the inscribed circle is GE

GE = -3y  + 18

GE = -3(2) + 18

GE = -6 + 18

GE = 12 units

Hence the measure of the radius of the inscribed circle is 12 units
