Answer: 50,400

Step-by-step explanation: 180 times 280 is like multiplying 180 by 280 times.

We can write 180 times 280 like this; 180 x 280.

180 x 280 = 50,400

Answer:

50,400

Step-by-step explanation:

180×280=50,400

Before multiplying two fractions together, always try to cross-cancel.

So in this problem, the 13 and 39 cross-cancel to 1 and 3.

So we have 1/15 × 11/3 which is 11/45.

Remember, multiply across the numerators and denominators.

To find the area of the larger figure, let's multiply the length by the width.

9 ft * 4 ft = 36ft^2

Let's do the same thing with the smaller figure.

3 ft * 4 ft = 12ft^2

Let's add the area of both figures together.

36ft^2 + 12ft^2 = 48ft^2

The answer is 42 because 590 minus 296 equals 294 and since the deadline is 17 days and he has done 10 already then 294 divided by 7 equals 42.

Answer: none of thoses

Step-by-step explanation:

Answer:

Remember that:

Speed = distance/time.

Then we can calculate the average speed in any segment,

Let's make a model where the average speed at t = t0 can be calculated as:

AS(t0) = (y(b) - y(a))/(b - a)

Where b is the next value of t0, and a is the previous value of t0. This is because t0 is the middle point in this segment.

Then:

if t0 = 100s

AS(100s) = (400ft - 0ft)/(200s - 0s) =   2ft/s

if t0 = 200s

AS(200s) = (1360ft - 50ft)/(300s - 100s) = 6.55 ft/s

if t0 = 300s

AS(300s) = (3200ft - 400ft)/(400s - 200s) =  14ft/s

if t0 = 400s

AS(400s) = (6250s - 1360s)/(500s - 300s) = 24.45 ft/s

So for the given options, t = 400s is the one where the velocity seems to be the biggest.

And this has a lot of sense, because while the distance between the values of time is constant (is always 100 seconds) we can see that the difference between consecutive values of y(t) is increasing.

Then we can conclude that the rocket is accelerating upwards, then as larger is the value of t, bigger will be the average velocity at that point.

Speed is simply the rate of change of distance over time.

The greatest speed is at [tex]t = 400[/tex]

To calculate the time of the greatest speed, we simply calculate the slope between each interval.

The slope (m) of a line is:

[tex]m = \frac{y_2 - y_1}{t_2 - t_1}[/tex]

When [tex]t = 100[/tex]

[tex](t_1,y_1) = (0,0)[/tex]

[tex](t_2,y_2) = (200,400)[/tex]

So, we have:

[tex]m = \frac{400-0}{200 -0}[/tex]

[tex]m= \frac{400}{200}[/tex]

[tex]m = 2[/tex]

When [tex]t = 200[/tex]

[tex](t_1,y_1) = (100,50)[/tex]

[tex](t_2,y_2) = (300,1360)[/tex]

So, we have:

[tex]m = \frac{1360-50}{300 -100}[/tex]

[tex]m = \frac{1310}{200}[/tex]

[tex]m = 6.55[/tex]

When [tex]t = 300[/tex]

[tex](t_1,y_1) = (200,400)[/tex]

[tex](t_2,y_2) = (400,3200)[/tex]

So, we have:

[tex]m = \frac{3200-400}{400 -200}[/tex]

[tex]m = \frac{2800}{200}[/tex]

[tex]m = 14[/tex]

When [tex]t = 400[/tex]

[tex](t_1,y_1) = (300,1360)[/tex]

[tex](t_2,y_2) = (500,6250)[/tex]

So, we have:

[tex]m = \frac{6250-1360}{500-300}[/tex]

[tex]m = \frac{4890}{200}[/tex]

[tex]m = 24.45[/tex]

From the above computation, the greatest speed (i.e. slope) is

[tex]m = 24.45[/tex]

The corresponding time at [tex]m = 24.45[/tex] is [tex]t = 400[/tex]

Hence, the greatest speed is at [tex]t = 400[/tex]

Step-by-step explanation:

The co-ordinates of point B is ( 10, 6 ).

A line segment is a subset of a line which has two endpoints.

According to the given question a  line segment AB has one endpoint at A(0, 0) which is (x₁,y₁)

Given midpoint is at (5,3).

Let B is (x₂,y₂).

We know midpoint of x is (x₁ + x₂)/2 and midpoint of y is (y₁ + y₂)/2.

∴ 5 = ( 0 + x₂ )/2

  5 = x₂/2

  x₂ = 10.

conditional equation

Step-by-step explanation:

Collecting terms on both sides, we get

6x−10−86x−18=9+4x−4x=9

Adding 18 to both sides of the equation, we get

6x=27

This can be solved by dividing by 6 on both sides of the equation, which gives a unique solution of 92. So, this is a conditional equation.

Answer:

Step-by-step explanation:

Answer:

60° =19π/3

288°=22π/9

315°=23π/4

80°=18π/5

Step-by-step explanation:

The question is incomplete. Find the completed question in the attachment.

We are to convert the radian values to the corresponding degrees that are less than 360°

Since π rad = 180°

For 23π/4:

If π rad = 180°

23π/4 = x

Cross multiply:

πx = 23π/4 × 180

x = 23π/4π × 180

x = (23×180)/4

x = 1035°

Next is to scale down 1035° to a degree less than 360 and to do this we will be subtracting multiples of 360° from the value gotten.

x = 1035 - (360×2)

x = 1035 - 720

x = 315°

Hence 23π/4 = 315°

For 18π/5:

If π rad = 180°

18π/5 = y

Cross multiply:

πy = 18π/5 × 180

y = 18π/5π × 180

y = (18×180)/5

y = 648°

In scaling down:

y = 648°-360°

y = 288°

Hence 18π/5 = 288°

For 22π/9:

If π rad = 180°

22π/9 = t

Cross multiply:

πt = 22π/9 × 180

t = 22π/9π × 180

t = (22×180)/9

t = 440°

In scaling down:

t = 440-360°

t = 80°

Hence 22π/9 = 80°

For 19π/3:

If π rad = 180°

19π/3 = y

Cross multiply:

πy = 19π/3 × 180

y = 19π/3π × 180

y = (19×180)/3

y = 3420/3

y = 1140°

In scaling down:

y = 1140°-(3×360)°

y = 1140-1080

y = 60°

Hence 19π/3 = 60°

Answer:

the other person was almost right except they mixed up 2 of them. this is the right answer, i hope this helps :)

60° =19π/3

288°=18π/5

315°=23π/4

80°=22π/9

Step-by-step explanation:

On the right side, 3 + 4 + 7 = 14, so the other two numbers must add up to 22.  Therefore, they must be 10 and 12.

Let's assume 12 is the top number and 10 is the bottom number.

The left side adds up to 12 + 9 + 2 = 23, so the other two numbers add up to 13.  Therefore, they must be 5 and 8.

The bottom side adds up to 10 + 1 + 11 = 22, so the other two numbers add up to 14.  Therefore, they must be 6 and 8.

So the bottom left number is 8.

Answer:

  5 months

Step-by-step explanation:

We assume that y represents production capacity, rather than increase in production capacity. Then we want to solve the 6th-degree equation ...

  x^6 -25x^4 +199x^2 -4975 = 0

This can be factored in groups as ...

  x^4(x^2 -25) + 199(x^2 -25) = 0

  (x^4 +199)(x^2 -25) = 0

This has 4 complex solutions and 2 real solutions.

  x^2 = 25

  x = ±5

The duration required for capacity to reach 4975 units is 5 months.
