Answer:

The length of the model is 6 inches.

Step-by-step explanation:

The wingspan of the airplane and length of the airplane are a ratio of 4:3

The model is also supposed to be 4:3.

4:3 x 2 = 8:6

Or, 20x12=240

240/8=30

15x12=180

180/30=6.

Group like terms

9x-5x=-10+6

4x=-4

Divide both sides by 4

x=-1

Hope it helps.

Answer:

x=-1

Step-by-step explanation:

4x=-10+6

4x-10+6

4x=-4

x=-4÷4

Answer:

x=6

Step-by-step explanation:

Step 1:

Subtract 3x from both sides:

4x + 8 - 3x = 3x + 14 - 3x

x + 8 = 14

Step 2:

Subtract 8 from both sides:

x + 8 - 8 = 14 - 8

x = 6

Answer:

x = 10

Step-by-step explanation:

Exterior angles in any polygon always measure 360°

x + 2x + 3x + 5x + 7x + 8x + 10x = 360°

36x = 360

  x = 360/36

  x = 10

Answer:

96 strawberries (c)

Step-by-step explanation:

the ratio from strawberry to tart:

4:1

the ratio if we have 24 tarts:

?:24

from multiplying the tart by 24 we must multiply the strawberries by 24 making the ratio:

96:24

The measure of m<QRX and m<QRP are 129 and 51 degrees respectively.

The sum of the interior angle of a triangle is 180 degrees, hence;

m<QPR + m<QRP + M<PQR = 180

Substitute the given parameters

49 + m<QRP + 80 = 180

m<QRP + 129 = 180

m<QRP = 180 - 129

m<QRP = 51 degrees

The sum of interior angle is equal to the exterior

m<QPR +  M<PQR = m<QRX

m<QRX = 49 + 80

m<QRX = 129 degrees

Hence the measure of m<QRX and m<QRP are 129 and 51 degrees respectively.

Answer:

x = 32

<1 = 102 degrees

<2 = 78 degrees

Step-by-step explanation:

3x + 6 + 2x + 14 = 180

5x + 20 = 180

5x = 180 - 20

x = 160/5

x = 32

3(32) + 6 = 102 degrees

180 - 102 = 78 degrees

Answer: - 4d

Step-by-step explanation:

In the equation, there's an invisible 1 in front of the first d, so let's add that.

1d - 2d - 3d

Since all the terms in the above equations are like terms, we would focus on only subtracting. We would first subtract 2d from 1d.

- 1d - 3d

We then subtract 3d from - 1d. This would give us our answer.

Answer:

  see attached

Step-by-step explanation:

The relevant trig relations are summarized by the mnemonic SOH CAH TOA. This means ...

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

  Tan = Opposite/Adjacent

So, for each triangle, determine the relationships of the given sides to the given angle: adjacent, opposite, or hypotenuse. Then write and solve the equation using one of the above templates.
