Answer:

9 minutes

Step-by-step explanation:

departure terminal A : 9:18 a.M

arrive terminal B : 10:03 a.M

time between B and A : 60 minutes (1 hour) - 18 minutes + 3 minutes = 45 minutes

arrive to a stop at : 9:58 a.M

time between A and stop : 58 minutes - 18 minutes = 40 minutes

5 mores tops including B

a stop - 1 stop next -2 stops next -3 stops next -4 stops next -B

average time between stops: 2 minutes

loading unloading time : 1 minute

a stop 40 minutes + (2 minutes to stop 1 + 1 minute in stop 1 )+ (2 minutes to stop 2 + 1 minute in stop 2 )+ (2 minute to stop 3 + 1 minute in stop 3 )+ (2 minutes to stop 4 + 1 minute in stop 4 )+ (2 minutes to stop B)

40 + 2 + 1 + 2 + 1 + 2+ 1 + 2+1 +2=54 minutes

real time between terminal B and A : 54 minutes

schedule time between terminal B and A : 45 minutes

minutes past scheduled time to arrive at Terminal B: 54 minutes -45 minutes=

9 minutes

A drink coaster in the shape of a circle has
egoroff_w [7]

The diameter of the coaster is 5 cm.

Step-by-step explanation:

Given,

The area of the circle = 19.63 sq inch

To find the diameter, we need to find the radius

Formula

The area of a circle with radius(r) = πr^{2} sq cm

According to the problem,

πr^{2}  = 19.63

or, r^{2} = \frac{7 X 19.63}{22}

= 6.2459

or, r = \sqrt{6.2459} = 2.499 (approx)

= 2.5 cm

Hence the diameter of the circle  = 2 × 2.5 cm = 5 cm

Solve 2x2 + 20x = −38.
Makovka662 [10]

Answer:

Correct Answer is C(−5 ±square root 6)

Step-by-step explanation:

2x^2+20x+38=0

2(x^2+10x+19)=0

x^2+10x+19=0

This is a quadratic equation here we have used following formula to find the roots of this equation

x=-b−±square root (b^2-4*a*c))/2*a......(1)

Here,

a=1

b=10

c=19

put values of a, b and c in equation (1)

x=(-10 ±square root(10^2-4*1*19))/2*1

x=(-10 ±square root(100-76))/2

x=(-10 ±square root(24))/2

x=(-10 ±square root(2*2*6))/2

x=(-10 ±2square root(6))/2

x=2(-5 ±square root(6))/2

x=-5 ±square root(6)

Please answer!!!!!!!!!!!!
vagabundo [1.1K]

Answer:

x = 14

A = 38

B = 71

C = 71

Step-by-step explanation:

3x-4 + 5x + 1 + 7x-27 = 180

15x-30 = 180

15x = 180 + 30

15x = 210

x = 210/15

x = 14

A = 3x-4 = 3(14) - 4 = 38

B = 5x + 1 = 5(14) + 1 = 70 + 1 = 71

C = 7x - 27 = 7(14) - 27 = 98-27 = 71

Tina ate 21 starbursts. If she ate 35% of the package of Starbursts, how many Starbursts are in the package?
mojhsa [17]

Answer:

60 starbursts

Step-by-step explanation:

We can set up an equation to find the answer. 21/x=0.35/1 because we're trying to find how many starbursts make up 100% of the package. So then to solve, we take 21x1 and then divide that by 0.35. From this we find that x=60.
