Step-by-step explanation:

Cir of circle Y = 2 πr = 138.23

Cir of circle Z = 2πr = 169.65

Answer:

Step-by-step explanation:

First, you distribute the 4 and 7 to the stuff inside the parentheses 28 - 12x = 28 - 14x then add 28 to both sides -12x = -14x then add 14x to both sides 2x = 0 then divide both sides by 2 x = 0

Answer:

x=0

Step-by-step explanation:

4(7-3x)=7(4-2x)

Distribute

28 -12x = 28 -14x

Subtract 28 from each side

-12x = -14x

Add 14x to each side

-12x+14x = -14x+14x

2x=0

x =0

Answer:

The Third One (0,-5) (2,9)

Step-by-step explanation:

Subtract y2-y1 and x2-x1 and the equation will come out as y=7x-5

Answer:

[tex]11, 5[/tex]

Step-by-step explanation:

[tex]x=y-6[/tex]

[tex]xy=55[/tex]

Put x as y-6 in the second equation.

[tex](y-6)y=55[/tex]

[tex]y^2-6y=55[/tex]

[tex]y^2-6y-55=0[/tex]

Factor.

[tex]\left(y+5\right)\left(y-11\right)=0[/tex]

[tex]\left(y+5\right)=0[/tex]

[tex]y=-5[/tex]

It has to be a positive integer.

[tex]y-11=0[/tex]

[tex]y=11[/tex]

Substitute y as 11.

[tex]x=y-6[/tex]

[tex]x=11-6[/tex]

[tex]x=5[/tex]

Answer:

5, 11.

Step-by-step explanation:

If the larger integer is x then the smaller one is x - 6.

Also x(x - 6) = 55

x^2 - 6x = 55

x^2 - 6x - 55 = 0

(x - 11)(x + 5) = 0

x = 11, -5.

We are given that x is positive so its value is 11.

The 2 integers are 5 and 11.

Answer:

Line r has a gradient of -1/2

Step-by-step explanation:

Perpendicular lines have a gradient of negative reciprocal to each other such that multiplying both the slopes give -1

=> Gradient of this line = 2

=> Gradient of line perpendicular to it = [tex]\frac{-1}{2}[/tex]

Multiplying both gradients:

=> 2 * [tex]\frac{-1}{2}[/tex]

=> -1

(SO They are perpendicular!)

Answer:

$22.95/hour.

Step-by-step explanation:

It is given that the average wage for an electrician in CA is $25.47/hour. That is 11% above the national average.

Let as consider x be the national average.

11% above the national average is

[tex]x+\dfrac{11}{100}x=x+0.11x=1.11x[/tex]

The average wage for an electrician in CA is 11% above the national average. So,

[tex]1.11x=25.47[/tex]

Divide both sides by 1.11.

[tex]x=\dfrac{25.47}{1.11}[/tex]

[tex]x=22.945945...[/tex]

[tex]x=22.95[/tex]

Therefore, the national average is $22.95/hour.

Answer:

Step-by-step explanation:

Data

Area of a triangle = base*height*1/2

If we take AB as a base, CX is the height, but if we take AC as a base, BY is the height. Therefore:

AB*CX*1/2 = AC*BY*1/2

Replacing with data:

CX = 70*60/75

CX = 56

Answer:

56

Step-by-step explanation:

The area of $\triangle ABC$ is half the base times the height. We can use any side as a base, with the perpendicular from the opposite vertex as the matching height.

Using $AC$ as a base, the area of $\triangle ABC$ is $\frac{AC\cdot BY}{2} = \frac{70\cdot 60}{2} = 2100$.

Using $AB$ as a base, the area of $\triangle ABC$ is $\frac{AB\cdot CX}{2} = \frac{75\cdot CX}{2}$. We already know that this is $2100$, so we can set up the equation

$$\frac{75\cdot CX}{2} = 2100.$$Solving this equation, we get

$$CX = \frac{2\cdot 2100}{75} = \boxed{56}.$$

Answer:

The area of a parallelogram is 360 in.²

Step-by-step explanation:

Where DG = GH

GP = 12 in.

AB = 39 in.

∠DAB + ∠ABC = 180° (Adjacent angles of a parallelogram)

Whereby ∠DAB is bisected by AG and ∠ABC is bisected by BH

Therefore, ∠GAB + ∠HBA = 90°

Hence, ∠BPA = 90° (Sum of interior angles of a triangle)

[tex]cos(\angle GAB) = \dfrac{AP}{AB} = \dfrac{AP}{39} = \dfrac{GP}{GH} =\dfrac{12}{GH}[/tex]

We note that ∠AGD = ∠GAB (Alternate angles of parallel lines)

∴ ∠AGD = ∠AGD since ∠AGD = ∠GAB (Bisected angle)

Hence AD = DG (Side length of isosceles triangle)

The bisector of ∠ADG is parallel to BH and will bisect AG at point Q

Hence ΔDAQ  ≅ ΔDGQ ≅ ΔGPH and AQ = QG = GP

Hence, AP = 3 × GP = 3 × 12 = 36

[tex]cos(\angle GAB) = \dfrac{AP}{AB} = \dfrac{36}{39}[/tex]

[tex]\angle GAB = cos^{-1} \left (\dfrac{36}{39} \right )[/tex]

∠GAB = 22.62°

[tex]cos(\angle GAB) = \dfrac{36}{39} = \dfrac{12}{GH}[/tex]

[tex]GH = \dfrac{39}{36} \times {12}[/tex]

GH = 13 in.

∴ AD 13 in.

BP = 39 × sin(22.62°) = 15 in.

GH = √(GP² + HP²)

∠DAB = 2 × 22.62° = 45.24°

The height of the parallelogram = AD × sin(∠DAB) =  13 × sin(45.24°)

The height of the parallelogram = 120/13 =  9.23 in.

The area of a parallelogram = Base × Height = (120/13) × 39 = 360 in.²

Answer:

360 in2

Step-by-step explanation:

The figure ABCD is a parallelogram, so the side AB is parallel to the side DC, and that means the angle mBAG is equal the angle mHGP.

The angles mHGP and mAGD are vertically opposite angles, so mHGP = mAGD.

The angle mDAG is equal the angle mBAG, so mDAG = mBAG = mHGP = mAGD

The angles mDAG and mAGD are equal, so the triangle DAG is isosceles, that means the side DG is equal the side DA.

In the same way, we can find that the angle mCBH is equal the angle mBHC, so triangle BCH is isosceles, meaning that side BC (which is equal side AD) is equal side CH, so we have that:

DG + GH + HC = AB = 39

GH + GH + GH = 39

GH = 13

in the parallelogram we have the property:

mDAB + mABC = 180°

We have that mGAB = mDAB/2 and mABH = mABC/2, so using this information for the sum of internal angles of triangle APB, we have:

mGAB + mABH + mBPA = 180

mDAB/2 + mABC/2 + mBPA = 180

(180/2) + mBPA = 180

mBPA = 90°

If the triangle APB is a right triangle, we can find the cosine of the angle mHGP:

cos(mHGP) = GP / GH = 12 / 13

Then, we can find the sine of mHGP using:

sin(mHGP)^2 + cos(mHGP)^2 = 1

sin(mHGP)^2 + 144/169 = 1

sin(mHGP)^2 = 25/169

sin(mHGP) = 5/13

If we draw the height of the triangle GPH relative to the side GH, we have:

sin(mHGP) = height / GP

5 / 13 = height / 12

height = 60/13

The triangles GPH and APB are similar (using the case angle-angle), so we can use this relation to find the height 'h2' of the triangle APB:

height / (h2+height) = GH / AB

(60/13) / (h2 + (60/13)) = 13/39 = 1/3

180 / 13 = h2 + (60/13)

h2 = 120/13

Then the area of the parallelogram is:

Area = AB * h2 = 39 * 120/13 = 360 in2

Answer:

the permutation of the alphabet or mixed (digits and letters)

Step-by-step explanation:

We are asked which method gives the greatest number of possible results when you want to configure a password, in this case our option is through combinations or permutations.

In a password the order matters, therefore it would be by the permutations method.

When creating a password it can be created with digits or letters, in general terms, digits are in less quantity than letters, therefore the greatest possible number would be through the permutation of the alphabet.

Although if you can do a mixed password, the result could have a higher number of outcomes

Answer:

The length of the radius is 3cm.

Step-by-step explanation:

Given that a circle is inscribed in a square. The side of the circle touches the side of the square which is the diameter. So the diameter of circle is 6cm, in order to find it's radius, you have to duvide it by 2 :

[tex]radius = diameter \div 2[/tex]

[tex]radius = 6 \div 2[/tex]

[tex]radius = 3cm[/tex]

Answer:

[tex]6^{2} - 3^{2} \pi[/tex] = area of the black  7.725666
