Answer:

10option a 10

11option d √58

12option b 16

13option d 68  

14option a 16

Step-by-step explanation:

To solve all these questions we will use trigonometry identity which says that

<h3>10)</h3>

TanФ = opp / adj

Tan (b) = 2/11

 b = tan^-1(2/11)

b =  10.30

   ≈ 10

<h3>11) </h3><h3>hypotenuse² = height² + base²</h3>

Bc² = 3² + 7²

BC = √3²+7²

BC =√58

<h3>12)</h3>

sin(30) = opp/ hypo

sin(30) = 8 / pq

pq = 16

<h3>13)</h3>

tanB = opp / adj

B = tan^-1(17/7)

B = 67.7 ≈ 68°  

<h3>14)</h3>

sin(7) = opp / hyp

sin(7) = 2/x

x =  2/sin(7)

x = 16 miles

function :  y = (-x) - 6

<u>Find x-intercept</u> :

  • (-x) - 6 = 0
  • (-x) = 6
  • x = -6

<u>Find y-intercept</u> :

  • y = (-0) - 6
  • y = -6

mark these two points on both the axis and draw a straight linear graph.

passes coordinates : (0, -6), (-6, 0)

Can someone help me the 2nd problem I don’t understand it
Galina-37 [17]

Answer:

So this means the bus B covered 390-120=270 miles when bus A has already reached 390 miles.

270 miles

Step-by-step explanation:

So is A is going faster than B so A will reach the destination first.

When will A reach it's destination?

Let's find out.

To solve this problem, the following will come in handy:

Speed=distance/time or time*Speed=distance or time=distance/speed .

time=distance/speed

T_A=\frac{390}{S_A}

T_A=\frac{390}{65}

T_A=6

So it will take bus A 6 hours to cover the distance of 390 miles.

How much time would have it taken bus B to reach that same distance?

T_B=\frac{390}{45}

T_B=8.\overline{6}

So it would have taken bus B 8.\overline{6} hours to cover a distance of 390 miles.

So the time difference is 8.\overline{6}-6=2.\overline{6} hours.

It will take 2.\overline{6} more hours than bus A for bus B to complete a distance of 390 miles.

So bus B traveled 2.\overline{6} \cdot 45=120 miles (used the time*speed=distance) after bus A got to it's destination.

So this means the bus B covered 390-120=270 miles when bus A has already reached 390 miles.

Vickie made a recipe for 144 fluid ounces of scented candle wax. How many 1 cup candle molds can she fill with the recipe?
jeka57 [31]
There are 8 fluid ounces in 1 cup.  You can solve this problem using these proportions:

\frac{8}{1} = \frac{144}{x}

It states that there are 8 fluid ounces in every 1 cup and 144 fluid ounces in every <em>x </em>cups.  We have to solve for <em>x </em>using cross-multiplication:

8x = 144 \\ x=18

Vickie can fill 18 1 cup candle molds with 144 fluid ounces of scented candle wax.
