Answer:

There were 200 passengers on the plane.

Step-by-step explanation:

1. 3/10  of the passengers were children -> 30% of the passengers were children

2. 60 children on the flight 30% of passengers = 60 people

divide by 3 -> 10% of passengers = 20 people

multiply by 10 -> 100% of passengers = 200 people.

Answer:

8 plantains

Step-by-step explanation:

48=$24

x=. $4

192=24x , x= 192÷24= 8

Answer:

8 plantains

Step-by-step explanation:

Cost and number of plantains are in proportion

Number of plantains that can be bought for $ 4 be 'x'

48 : 24 :: x : 4

Product of means = product of extremes

24 * x = 48*4

       [tex]x = \frac{48*4}{24}[/tex]

      x = 2 * 4

      x = 8

Answer:

No solution

Step-by-step explanation:

The given equations are :

9x-3y=-6

3x-y=2.....(1)

5y=15x+10

5y-15x=10

or

y-3x=2 .....(2)

Equations (1) and (2) shows that the lines are parallel. We know that for parallel lines, there is no solution.

Answer:

2100 second

Step-by-step explanation:

4:30 pm to minutes

4 × 60 + 30 = 240 + 30

= 270 minutes

5:05 to minutes

5 × 60 + 5 = 300 + 5

= 305

4:30 to 5:05

305 - 270

= 35 minutes

35 minutes to second

35 × 60

= 2100 second

Answer:

2100

Step-by-step explanation:

25 minutes you need to know that 60 sec =1 hour.35x60=2100

Answer:

The answer would be C

Step-by-step explanation:

To find the answer square the 12 yds and subtract that from 30 yds squared. That will leave you with 27.49, and you would just round that decimal up to 27.5 for youir answer.

Answer:

X = 5 u

m∠4 = 85º

m∠ = 85º

Step-by-step explanation:

17x = 9x + 40

17x-9x = 40

8x = 40

x = 40/8

x = 5

m∠4 = (17x)º = (17*5)º = 85º

m∠ = (9x+40)º = (9*5 + 40)º = (45 + 40)º = 85º

Answer:

y=29

Step-by-step explanation:

y+12 - 12 = 41 -12

y=29

Answer:

y = 29

Step-by-step explanation:

subtract 12 on both sides to isolate & solve for y:

y + 12 = 41

    - 12  -12

=> y = 41 - 12

=> y = 29

Answer:

Uhhhhhh, nothing?

Step-by-step explanation:

Answer:

See below

Step-by-step explanation:

we are given two functions

[tex] \displaystyle \begin{cases}f(x) = - x + 5 \\ g(x) = {x}^{2} - 3x + 2\end{cases}[/tex]

where f(x) is a linear function and g(x) is a quadratic function

we want to figure out the solutions of the function

let's graph f(x):

the Black-table is attached

let's graph g(x):

the picture is attached

hence, the graph should be

the graph is attached

so we need solution(s) which satisfy(ies) the both functions

in this case the solution (s) the x coordinate(s) where both functions intercept we get from the graph that both functions intercept at (-1,6) and (3,2)

hence,

x={-1,3}

Answer: 25 square units

You can divide the shape off into manageable chunks then multiply to find the answer!

Answer:

x = 19°

y = 31°

Step-by-step explanation:

5x = 7x - 38

2x = 38

x = 19

y = 180 - 54 - 5(19)

y = 31

Velocity=226mph

Angle made with horizontal= 18°

The vector components would be [tex] 226~sin18° \hat{j} + 226~cos18° \hat{i} [/tex]

The vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°

What is a Vector ?

An parameter that has both magnitude and direction is called a vector.

It is given that

Speed S = 226 mph

Angle = 18 degree with the horizontal

The vector component are

[tex]\rm v_x , v_y[/tex]

here these are x and y components of the vector

V is the magnitude = |v| = 226

The vector component is given by

cos [tex]\rm \theta[/tex] = [tex]\rm v_x[/tex] / |v|

[tex]\rm v_x[/tex] = 226 cos 18°

[tex]\rm v_y[/tex] = 226 sin 18°

Therefore the vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°

Answer:

B

Step-by-step explanation:

first of all we have to multiply 9√3 for each members in the brackets. For do this we have to multiply number x number and roots x roots

(9x8) = 72

(√3)^2 = 3

72 x 3 = 216

9 x 9 = 81

√3 x √5 = √15

81√15

now we have to added up the two results

216 + 81√15

Answer:

71.549

Step-by-step explanation:

Answer:

The sum of 50.249 + 21.3 is 71.549.

Step-by-step explanation:

50.249 + 21.3 can be written as (50 + 20) + (0 + 1) + (0.2 + 0.3) + 0.049, which makes calculating the sum easier. 50 + 20 = 70, 0 + 1 = 1, 0.2 + 0.3 = 0.5, and you still have a 0.049. Add the numbers all together and you'll get that the sum of 50.249 and 21.3 is 70 + 1 + 0.5 + 0.049 or 71.549.

Answer:

Value of x = 87°

Step-by-step explanation:

Given:

∠1 = 102°

∠2 = x + 15°

Find:

Value of x

Computation:

We know that, given two lines are parallel and third line interest that

So,

Corresponding angles are equal

So,

∠1 = ∠2

x + 15 = 102

x = 87

Value of x = 87°
