Answer:

66 tens

Step-by-step explanation:

Required

Solve 66 hundreds / 10

First, we need to express 66 hundreds as a number.

1 hundred = 100

66 hundreds = 66 * 1 hundred

So:

66 hundreds = 66 * 100

66 hundreds = 6600

66 hundreds / 10 would then be calculated as:

66 hundreds / 10 = 6600/10

66 hundreds / 10 = 660

660 can be represented as:

66 hundreds / 10 = 66 * 10

or

66 hundreds / 10 = 66 tens

Hence, option C answers the question

3. Alt. Interior Angles

4. definition of midpoint

Answer:

a. 360.323 m

b. [tex]95.265^{o}[/tex]

Step-by-step explanation:

Distance covered from A to B = speed x time

                                                 = 110 x 2.8

                                                 = 308 m

Distance covered from B to C = speed x time

                                                  = 110 x 1.7

                                                  = 187 m

The sum of angles at B = [tex]64^{o}[/tex] + [tex]26^{o}[/tex]

                                       = [tex]90^{o}[/tex]

a. The distance of the plane from it starting point to C can be determined by applying the cosine rule.

[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] - 2ac Cos B

Sot hat;

[tex]b^{2}[/tex] = [tex]187^{2}[/tex] + [tex]308^{2}[/tex] - 2(187 x 308) Cos [tex]90^{o}[/tex]

But, Cos [tex]90^{o}[/tex] = 0

So that,

[tex]b^{2}[/tex] = [tex]187^{2}[/tex] + [tex]308^{2}[/tex]

  = 34969 + 94864

  = 129833

b = [tex]\sqrt{129833}[/tex]

  = 360.323

The distance from A to C is 360.323 m.

b. Applying the sine rule;

[tex]\frac{a}{SinA}[/tex] = [tex]\frac{b}{SinB}[/tex]

[tex]\frac{187}{SinA}[/tex] = [tex]\frac{360.323}{Sin90^{o} }[/tex]

[tex]\frac{187}{SinA}[/tex] = [tex]\frac{360.323}{1}[/tex]

Sin A = [tex]\frac{187}{360.323}[/tex]

         = 0.5190

⇒ A = [tex]Sin^{-1}[/tex] 0.5190

       = [tex]31.265^{o}[/tex]

The bearing of the plane from its original location = [tex]64^{o}[/tex] + [tex]31.265^{o}[/tex]

                                                     = [tex]95.265^{o}[/tex]

Using the Sine and Cosine rule on the triangle generated using the information given, the distance and bearing of the plane from its original location are :

Using the Cosine Rule :

b² = 187² + 308² - 2(187)(308)Cos(90°)

b² = 187² + 308² - 0

b² = 129833

b = √129833

b = 360.32 miles

B.)

Using the Sine rule :

a/sinA = b/SinB = c/SinC

187/sinA = 360.32/sin90

187/sinA = 360.32/1

sinA × 360.32 = 187

sinA = 187 / 360.32

sinA = 0.51898

A = Sin¯¹(0.51898)

A = 31.264

Hence, bearing of C from A = (64° + 31.264) = 95.26°

Answer:

(96/5) mph, or 19.2 mph

Step-by-step explanation:

Average speed = (total distance traveled) / (total time elapsed)

Here we need to calculate the two elapsed times (going and returning)

Going:  t1 = d/(24 mph)

Returning:  t2 = d/(16 mph)

Less time is required for the outward bound trip.

                                                                            16d + 24d

Total time elapsed:  t = t1 + t2 = d/24 + d/16 = ------------------- = (5/48)*d hr

                                                                                 16*24

Thus, the average speed is (total distance traveled) / (total elapsed time)

                                2d

which here is --------------------- = (96/5) mph, or 19.2 mph

                             (5/48)d

If we take average speed into account in any direction, it equals (24 + 16) / 2 = 40 / 2 = 20mph.

If we consider speed in any direction, the average speed is:

(24 + 16) / 2 = 40 / 2 = 20mph

However, if direction is important, one number must be negative because the directions are opposite:

(24 - 16) / 2 = 8 / 2 = 4mph (in the positive direction)

Depending on the circumstances, either of these could be your response.

Answer:

C = 5.50S + 9L

.............

The equation that relates the cost, Cin dollars with the number of small toy cars, S, and the number of large cars, L is  C = 5.50S + 9L.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A hobby shop sells small and large toy cars. A small toy car is $5.50, and a large toy car is $9.

Let S be the number of a small toy car and L be the number of a large toy car.

The equation can be made:

Total cost:

C = 5.50S + 9L

Thus, the equation that relates the cost, Cin dollars with the number of small toy cars, S, and the number of large cars, L is  C = 5.50S + 9L.

Answer:

m=−16

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4m−5(3m+10)=126

4m+(−5)(3m)+(−5)(10)=126(Distribute)

4m+−15m+−50=126

(4m+−15m)+(−50)=126(Combine Like Terms)

−11m+−50=126

−11m−50=126

Step 2: Add 50 to both sides.

−11m−50+50=126+50

−11m=176

Step 3: Divide both sides by -11.

−11m /−11 = 176 /−11

m=−16
