Answer:

32.5

Step-by-step explanation:

We can set this problem up as a proportion:

[tex]\frac{10}{25} = \frac{13}{x}[/tex] In doing this, we find the exact distance from Boomtown to Dayville. Another way to do it is by dividing 25 by 10, to get 2.5, then multiplying 2.5 by 13 to get 32.5

Answer:

exact form is 95/8 decimal form 11.875 and mixed number form n= 11 7/8

Answer:

11.4

Step-by-step explanation:

Since this triangle is a right triangle, we can solve using SOHCAHTOA.

Our angle is 25 degrees and the given hypotenuse length is 27. So, the best trigonometry equation to use would be sine, since it includes the hypotenuse and the opposite side, which is the r length that we are looking for.

Through SOHCAHTOA, sin 25° = [tex]\frac{opp}{hyp}[/tex]

sin 25° = [tex]\frac{r}{27}[/tex]

r = 27 (sin 25°)

Using a calculator, 27 (sin 25°) ≈ 11.4

Answer: The number of seats in each of the rows at the front =204

Step-by-step explanation:

Let x = The number of seats in each of the rows at the front.

Given: Total seats = 15,600

Total rows = 60

Rows in back = 35

Rows in front = 60-35=25

Total seats in front = 25x

Each row in the back has 300 seats.

Total seats in the back =300 x35=10500

Seats in front = 15600-10500=5100

i.e. [tex]25x=5100\Rightarrow x=\dfrac{5100}{25}=204[/tex]

Hence, the number of seats in each of the rows at the front =204

Answer:

x = 1

y = -2

Step-by-step explanation:

We have the system of equations:

-7*x - 8*y = 9

-4*x + 9*y = -22

To solve this type of system, we need to start by isolating one of the variables in one of the equations.

I will isolate the variable x in the first equation to get:

-7*x - 8*y = 9

-7*x = 9 + 8*y

x = (9 + 8*y)/(-7)

x = -(9 + 8*y)/7

Now we can replace this in the other equation to get:

-4*(-(9 + 8*y)/7) + 9*y = -22

And now we can solve this for y, we will get:

(4/7)*(9 + 8*y) + 9*y = -22

(4/7)*9 + y*(9 + 8*(4/7)) = -22

y*(63/7 + 32/7) = -22 - (36/7)

y*(95/7) = -(22*7/7) - (36/7)

y = (7/95)*(-(22*7/7) - (36/7)) = (-22*7 - 36)/95 = -2

y = - 2

Now we can replace this in the equation x = (9 + 8*y)/(-7) to find the value of x:

x = (9 +8*(-2))/(-7) = 1

Then the solution for the system is the pair (1, -2)

That means:

x = 1

y = -2

Answer:

x = 111

Step-by-step explanation:

x + x - 42  = 180     {Lines are parallel. So, they are supplementary}

2x - 42 = 180  

Add 42 to both sides

2x - 42 + 42 = 180 + 42

               2x = 222          {Divide both sides by 2}

                 x = 222/2

x = 111

Answer:

36

Step-by-step explanation:

8x + 4 = 4x + 20

8x - 4x = 20 - 4

4x = 16 divide both sides by 4

x = 4 and JM = 8x + 4 replace x with 4

8×4 + 4 = 36

Answer:

36

Step-by-step explanation:

8x + 4 = 4x + 20 ( being opposite sides of parallelogram)

8x - 4x = 20 - 4

4x = 16

x = 16 / 4

x = 4

JM = 8x + 4

=8 * 4 + 4

= 32 + 4

= 36

Answer:

41.472 m²

8.449m²

Step-by-step explanation:

c) scale facot is 7.2/5 = 1.44

the square scale factor is 1.44^2 = 2.0736

times 20 by this to get the area

2.0737x 20 = 41.472 m²

d) 2.8/6 = SF = 0.467

0.2178 x 38.8 = 8.449m²

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

Explanation:

Refer to the diagram below.

If we focus on triangle ACD, then we can use the pythagorean theorem to say

d^2 + m^2 = 2050^2

d^2 = 2050^2 - m^2

Now if we focus on triangle DCB, we can also use the pythagorean theorem to say

d^2 + n^2 = 1420^2

2050^2 - m^2 + n^2 = 1420^2 ...... replace d^2 with 2050^2 - m^2

n^2 - m^2 = 1420^2 - 2050^2

n^2 - m^2 = -2,186,100

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

In the diagram, I set up m and n such that m+n = 3000. This solves to n = 3000-m

We can then say

n^2 - m^2 = -2,186,100

(3000-m)^2 - m^2 = -2,186,100

m^2 - 6000m + 9,000,000 - m^2 = -2,186,100

-6000m + 9,000,000 = -2,186,100

-6000m = -2,186,100 - 9,000,000

-6000m = -11,186,100

m = (-11,186,100)/(-6000)

m = 1864.35

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

We now have enough to find angle theta, which is the angle between segments AC and AD (the line of sight to the first tower and the highway lines respectively)

We'll focus entirely on triangle ACD

cos(angle) = adjacent/hypotenuse

cos(A) = AD/AC

cos(theta) = m/2050

cos(theta) = 1864.35/2050

cos(theta) = 0.90943902439024 which is approximate

theta = arccos(0.90943902439024)

theta = 24.572056388088

theta = 24.6 degrees

Make sure your calculator is in degree mode. One way to check is that cos(60) should evaluate to 0.5

Answer:

8/49

Step-by-step explanation:

Given data

Sample space

4 red marbles

8 blue marbles

2 green

Sample size

4+8+2 = 14

Pr(picking a red)

Pr(red)= 4/14= 2/7

With replacement

Pr(picking a blue)

Pr(blue)= 8/14= 4/7

Hence the probability of picking a red marble, replacing the item, and then picking a blue marble

= 2/7*4/7

= 8/49

Answer:

positive and negative or c1

Step-by-step explanation:

When you use the distributive property, you multiply everything inside the parentheses by the number outside of the parentheses. When you distribute, the equation becomes 5x+20=60 vs 5x+4= 60. Hope this helps!

Step-by-step explanation:

Answer:

31.5

Step-by-step explanation:

Ok.

2/3x - 9 = 12

2/3x = 21

x = 21*(3/2)

x = 63/2 = 31.5

Answer:

[tex]x=\frac{63}{2}[/tex]

Step-by-step explanation:

[tex]\frac{2}{3} \times x-9=12[/tex]

Add 9 to both sides:

[tex]\frac{2}{3}x-9+9=12+9\\\frac{2}{3}x=21[/tex]

Multiply both sides by 3/2:

[tex](\frac{3}{2} )\times(\frac{2}{3}x)=(\frac{3}{2} )*(21)\\x=\frac{63}{2}[/tex]

x = 63/2 is your answer.
