Answer:

  14.9 cm

Step-by-step explanation:

To find c using the Law of Sines, you must know angle C. That is found from ...

  C = 180° -A -B = 180° -150° -12° = 18°

Then the law of sines tells you ...

  c/sin(C) = b/sin(B)

  c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)

  c ≈ 14.9 cm

Answer:

26

Step-by-step explanation:

2,652÷102 which gives you 26

The minimum number of additional buses the school will need to purchase is 26.

The division is a method of distributing a group of things into equal parts.

According to the question

Total bus riders = 2652

Each bus can hold 102 students.

Minimum number of buses need to purchase

= [tex]\frac{2652}{102}[/tex]

= 26

Hence, the minimum number of additional buses the school will need to purchase is 26.

Well on my end i got 47.12, with pi included

Step-by-step explanation:

The surface area of the cylinder with the diameter 2cm and height 15cm  is [tex]100.48 \; cm^2[/tex]

Calculation to find Surface area of cylinder:

Given the diameter of the cylinder is 2cm and height  15cm

Formula :

The surface area of the cylinder =[tex]2\pi r^2+2\pi rh[/tex]

where 'r' is the radius and 'h' is the height of the cylinder

Diameter = 2cm

[tex]radius =\frac{diameter }{2} =\frac{2}{2} =1[/tex]

radius = 1cm and height is 15 cm

the value of pi is 3.14

Substiute all the values

[tex]SA = 2\pi r^2+2\pi rh\\SA=2(3.14)(1)^2+2(3.14)(1)(15)\\SA=6.28+94.2\\SA=100.48 cm^2[/tex]

Answer:

(2x - 3)/(x +4)

Step-by-step explanation:

Given the expression 4x^2 - 9/2x^2+11x+12

Simplify the numerator

4x^2 - 9 = (2x)^2 - 3^2

Recall that a^2 - b^2 = (a-b)(a+b)

Hence 4x^2 - 9 = (2x - 3)(2x + 3)

The denominator

2x^2+11x+12

Factorize

2x^2+11x+12 = 2x^2+8x + 3x+12

=2x(x + 4) + 3(x + 4)

= (2x + 3)(x + 4)

Hence

4x^2 - 9/2x^2+11x+12 =  (2x - 3)(2x + 3)/(2x + 3)(x + 4)

= (2x - 3)/(x +4)

Answer:

[tex]y=\frac{5}{4} x[/tex]+17

Step-by-step explanation:

Okay for this you take the point (-8+7) and plug it into the equation getting you this 7=[tex]\frac{5}{4}[/tex](-8)+b

If you multiple [tex]\frac{5}{4\\}[/tex] by -8 you get -10

You then add -10 to the other side to get 17

that means 17=b

meaning you get [tex]y=\frac{5}{4} x[/tex]+17 by plugging in 17 to b

Answer:

m = 1/3, b = 2

Step-by-step explanation:

The equation is already written is slope-intercept form, y = m x + b.

Answer:

Let x be the number of 1 point shots, and y be the number of 2 point shots.

So the system is:

x+y=53

1x+2y=90

We can solve this system by substitution.

x+y=53, x=53-y

x+2y=90

53-y+2y=90

53+y=90

y=37

That means, the team made 37 two point shots.

If the team made 37 two point shots, the team scored 37 x 2, or 74 points from 2 point shots, meaning that it made 16 one  point shots.

So the correct answer is: 16 one point shots, 37 two point shots.

Answer:

You should mail about 4000 letters each day.

Step-by-step explanation:

25% of 80,000 is 20,000

20,000(1/5) = 4,000

The total amount that is planned to mail the letters each day is 4,000.

Given,

Computation:

[tex]\begin{aligned}\text{Total Amount}&=(\text{Total Amount of Letters}\times\%\text{in next 5 Days})\times\text{Proportion of Each Day}\\&=(80,000\times25\%)\times\dfrac{1}{5}\\&=20,000\times\dfrac{1}{5}\\&=4,000\end{aligned}[/tex]
