Answer:

(n + 1) (5m + 4)

Step-by-step explanation:

⇒ (n + 1) (5m + 4)

⇒ 5mn + 4n + 5m + 4

⇒ 5mn + 5m + 4n + 4

Answer:

(n + 1)(5m + 4)

Step-by-step explanation:

Given

5mn + 5m + 4n + 4 ( factor the first/second terms and the third/fourth terms )

= 5m(n + 1) + 4(n + 1) ← factor out (n + 1) from each term

= (n + 1)(5m + 4)

Answer:A he is correct because the inner circle is a dilation of the outer circle

Step-by-step explanation: just did the test

The statement "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.

Dilation is the process of modifying the size of an item or form by reducing or expanding its dimensions according to specific scaling variables.

The radius of the inner circle is 2 units, while the radius of the outer circle is 5 units.

Since dilations provide similar figures because multiplying by the scale factor yields proportionate sides while keeping the angle measure and form constant.

Troy is accurate if he claims the two circles are similar.

Hence, the statement (A) "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.

Answer: X = 30*

All circles = 360*

we can subtract 260 from that because we know the length of one so we know the other is 130.

We are then left with only 100 and we know the two sides are equivalent so 100 / 2 = 50

Answer:x = -1 / 12

Step-by-step explanation: am i right??

8x + 8y = 2 -------(1)

8x + 5y = 1 -------(2)

subtract equation (2) from equation (1)

The 8x will be eliminated, leaving us with;

3y = 1

Divide bothside of the equation by 3

y = 1/3

substituting y = 1/3 in equation (1)

8x + 8y = 2

8x + 8(1/3) = 2

8x + 8/3 = 2

subtract 8/3 from both-side

8x + 8/3 -8/3 = 2 -8/3

8x = 2 - 8/3

8x = 6 - 8 / 3

8x = - 2/3

Divide both-side of the equation by 8

8x / 8 = -2/3 ÷ 8

x = -2/3 × 1/8

x = -1 / 12

Answer:

Step-by-step explanation:

sin(D) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

         = [tex]\frac{7}{14}[/tex]

         = [tex]\frac{1}{2}[/tex]

         = 0.5

cos(D) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

          = [tex]\frac{12.124}{14}[/tex]

          = 0.866

tanD = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

        = [tex]\frac{7}{12.124}[/tex]

        = 0.577

Since, sinE = cosD

Therefore, sinE = 0.866

Since, cosE = sinD

Therefore, cosE = 0.5

Since, tanE = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

                   = [tex]\frac{12.124}{7}[/tex]

                   = 1.732

Answer:

a31 = -334

Step-by-step explanation:

Given:

a1 = 26

a22 = -226

Find:

a31

Computation:

a22 = a + 21d

-226 = 26 + 21d

d = -12

a31 = a + 30d

a31 = 26 + 30(-12)

a31 = 26 - 360

a31 = -334

a1 = 26 and a22 = −226.

Answer:

A)  −334

Answer:

Outside of the circle

Step-by-step explanation:

First, find the equation of the circle by plugging in the center point and radius:

(x - h)² + (y - k)² = r²

(x - 0)² + (y - 0)² = ([tex]2\sqrt{3}[/tex])²

x² + y² = 12

Plug in point M to see where it lies:

x² + y² = 12

(-3)² + (2)² = 12

9 + 4 = 12

13 ≠ 12

Since this statement is false, point M lies outside of the circle.

Answer: The walking path around it.

Step-by-step explanation:

Remember the Pythagorean's theorem, for a triangle rectangle with catheti A and B, and with hypotenuse H, we have:

A^2 + B^2 = H^2

or

H = √(A^2 + B^2)

Here, A + B is the total distance for the path, while the hypotenuse is the distance for the bridge

Here we can see that:

A = 1170 ft

B = 520 ft

Then:

H = √( (520 ft)^2 + (1170 ft)^2) = 1280.4 ft

Now, let's compute the costs.

For the bridge, we know that each foot costs $11, then for 1280.4 ft the cost is:

Cost of the bridge = (1280.4)*$11 = $14,084.4

And for the walking path, the cost is $6 per foot, then the total cost of the path is:

Cost of the path = (520 ft + 1170 ft)*$6 = $10,140

We know that the bridge is preferred if it is within the range of $1500 for the path's cost.

This range is:

($10,140 - $1,500, $10,140 + $1,500) = ($8,640, $11,640)

Here we can see that the cost of the bridge does not belong to this range, (is higher) so the option we should recommend is the walking path around.

Answer:

12.75feet (12¾)

Step-by-step explanation:

7t+1+5t+8=162feet

12t+9=162feet

12t=162-9

=153

t = 153÷9

=12.75feet (12¾feet)

Answer:

350

Step-by-step explanation:

so the first step is to find the values of each of them

7x10^6=7000000

2x10^4=20000

then we divide 7000000 by 20000

7000000/20000=350

so the answer is 350

Answer:

y=67.7 Degrees

Step-by-step explanation:

You're given the opposite and adjacent sides to angle Y, so we use Tan to find the angle:

Tan(y)= 100/41

We then inverse tan to isolate y

y=tan^-1 100/41

y=67.7 Degrees
