Answer:

(a) Reduction

(b) scale factor = 1/2

Step-by-step explanation:

(a)  A reduction is a dilation that creates a smaller image.  

As A'B'C'D' is smaller than ABCD, image A'B'C'D' is a reduction of image ABCD.

(b)  To find the scale factor:

center of dilation = (0, 0)

(0, 0) to point C = 4 units

(0, 0) to point C' = 2 units

⇒ scale factor = 2/4 = 1/2

Answer:

B

Step-by-step explanation:

6-1+11 +8

5x+19

therefore the answer is 5x + 19

The expression which is equivalent to 5x - 19 is D) -3x + 4(2x - 6) + 5.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given an expression,

5x - 19

We have to find the equivalent expression.

Find the value of each expression in the options.

A) 7(4 - 2x) + 9 (x - 1) = 28 - 14x + 9x - 9 = -5x + 19

B) 6x - (x - 11) + 8

= 5x + 11 + 8 = 5x + 19

C) 10 - 3(x - 3) - 2x

10 - 3x + 9 - 2x = -5x + 19

D) -3x + 4(2x - 6) + 5

-3x + 8x - 24 + 5 = 5x - 19

Hence the correct option is D.

The area of the triangle is equal to 12 mm².

The area of a triangle is given by the formula:[tex]A=\frac{bh}{2}[/tex], where:

 b= length of the base;

  h=height

From the figure, it is possible to see that h= base of rectangle - 4 mm. Then, the height of the triangle(h)= 10-4=6 mm.

You can see that the sum of the base of the triangle with the height of the rectangle is equal to 12 mm. The figure also shows that the height of this rectangle is equal to 8 mm. Thus, the  base of the triangle(h)= 12-8=4 mm.

STEP 2 - Find the area of the triangle.

From step 1:

    b= length of the base= 4

    h=height=6

Therefore, the area of the triangle - [tex]A=\frac{bh}{2}=\frac{4 * 6}{2}=\frac{24}{2} =12 mm^2[/tex].

Answer:

mP = 35

Step-by-step explanation:

QR = 80

QS = 150

The measure of the angle formed by a secant and a tangent intersecting in the exterior of a circle is half the difference between the measures of the intercepted arcs.

This means that (150-80)/2 = mP

mP = 35 degrees

Answer:

30 inches

Step-by-step explanation:

In equilateral triangle all sides are equal. One side of the triangle EB is also the  side of a square.

So, all the sides of the square is 6 inches

Perimeter = sum of all sides

                  = AB  + BC + CD + DE + EA

                  = 6 + 6 + 6 + 6 + 6

                  = 5*6

                   = 30 inches

Answer:

Here,

length of the square BCDE(l)= 6 inches

Also,

length of the equilateral triangle ABE(l)=6 inches

Lastly, Perimeter of figure ABCDE= 5*6

=30 inches

or,Perimeter of the figure ABCDE also=

AB+BC+CD+DE+EA

=6+6+6+6+6

=30inches

Step-by-step explanation:

We know,

length DC of the square BCDE(l)=6inches

So,

DC=BC=BE=DE (All sides of a square are equal)

Again,

length BE of the equilateral triangle ABE=6inches

So,

BE=AB=AE (All sides of a equilateral triangle are equal)

Therefore, Perimeter of figure ABCDE=

AB+BC+CD+DE+EA or, 5*6

(perimeter means to sum all the outer sides a given polygon, in this case it's a Pentagon)

An equation is formed of two equal expressions. There is no solution set of the equation 3x+13 = 3(x+6)+1.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation can be solved in the following manner,

[tex]3x+13 = 3(x+6)+1\\3x+13=3x+18+1\\3x+13=3x+19[/tex]

Since both the sides of the equation are the same in terms of variable and the constant terms are not the same. Therefore, there is no solution set of the equation 3x+13 = 3(x+6)+1.

y=31,006,000(1+.012)^x

Step-by-step explanation:

all coefficients are integers, the rational zeros theorem can be applied.

that means each rational solution ("root") x = p/q, written in most simplified terms so that p and q are relatively prime, can be found for the polynomial

an×x^n + an-1×x^(n-1) + ... + a1×x + a0

p is an ± integer factor of the constant term a0, and

q is an ± integer factor of the leading coefficient an.

in our case here

an = a4 = 1

a0 = 8

the only factor for 1 is ±1.

the factors for 8 are

±1, ±2, ±4, ±8

so, we get

1/1, 2/1, 4/1, 8/1, -1/1, -2/1, -4/1, -8/1, 1/-1, 2/-1, 4/-1, 8/-1, -1/-1, -2/-1, -4/-1, -8/-1

sorted from smallest to largest

-8/1, -4/1, -2/1, -1/1, 1/1, 2/1, 4/1, 8/1

A circle is a curve sketched out by a point moving in a plane. The measure of x is 60°.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

Given that the measure of the arc AC is 120°. Now, as we know, the diameter divides the circle into two equal chords of 180° each. Therefore, the measure of x can be written as,

[tex]x = {\rm arcAB-arc AC}\\\\x = 180^o-120^o\\\\x = 60^o[/tex]

Hence, the measure of x is 60°.

Answer:

30°

Explanation:

∠LMP + ∠PMN = 180°

[∠LMO + ∠OMP] + [∠PMR + ∠RMN] = 180°

FIND x

(x - 10) + (x + 30) + x + 40 = 180

3x - 10 + 30 + 40 = 180

3x + 60 = 180

3x = 120

x =40

FIND ∠LMO

∠LMO = x - 10

∠LMO = (40) - 10

∠LMO = 30°

Hope this helps and God bless!

Answer:

∠LMO = 30°

Step-by-step explanation:

Angles on a straight line add up to 180°

⇒ (x - 10)° + (x + 30)° + 40° + x° = 180°

⇒ x° + x° + x° - 10° + 30° + 40° = 180°

⇒ 3x° + 60° = 180°

⇒ 3x° = 120°

⇒ x = 40

Substitute found value of x into the expression for ∠LMO:

⇒ ∠LMO = (40 - 10)°

⇒ ∠LMO = 30°

Using proportions, it is found that you would expect to get a sum of 3 22 times.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

When two dice are rolled, there are 36 total outcomes. 2 of them, (1,2) and (2,1), result in a sum of 3, hence the proportion is given by:

p = 2/36 = 1/18.

Out of 396 tosses, the expected value is given by:
