Two cars leave simultaneously from points A and B, the distance between which is 280 km. If the cars move to meet each other, they’ll meet in 2 hours. But if they move in the same direction, then the car going from point A will catch up with the car going from point B in 14 hours. What is the speed of each of the cars?

Answers

Answer 1

Answer:

Car A speed = 80 m/s

Car B speed = 60 m/s

Step-by-step explanation:

Let Speed of Car A be represented as x

Let Speed of Car B be represented as y

280 = (x+y)(2)140 = x+y --> Equation 1

Let z represent the distance that Car A travels until it catches up to Car B

280+z = x(14)

Since it takes 14 hours for Car B to cover the distance z,

z = 14y280+14y = 14x280 = 14(x-y)20 = x-y --> Equation 2

Solving Equation 1 and Equation 2, we get:

x = y+20140 = 2y+20120 = 2yy = 60 x = y+20 = 80

Answer 2

Answer:

Car A speed = 80 km/h

Car B speed = 60 km/h

[tex]x=\dfrac{\sqrt6 \sqrt 2}{2}[/tex]

Step-by-step explanation:

We need to find the value of x.

Here, Hypotenuse = √6

Perpendicular = x

We know that,

[tex]\sin\theta=\dfrac{P}{H}[/tex]

So,

[tex]\sin(45)=\dfrac{x}{\sqrt6}\\\\x=\sin(45)\times \sqrt{6} \\\\x=\dfrac{\sqrt{6}}{\sqrt{2} }\\\\x=\dfrac{\sqrt{6}}{\sqrt{2} }\times \dfrac{\sqrt2}{\sqrt2}\\\\x=\dfrac{\sqrt6 \times \sqrt 2}{2}\\\\x=\dfrac{\sqrt6 \sqrt 2}{2}[/tex]

So, the value of x is equal to [tex]\dfrac{\sqrt6 \sqrt 2}{2}[/tex].

Ragon, who lives on this planet, does a survey and finds that her colony of 237 contains 45 black-footed, one-headed Mizjigs; 69 red-footed, two-headed Mizjigs; and 115 one-headed Mizjigs.
How many black footed Mizjigs are there in Ragon's colony?

Answers

The answer is A. 98.

Because when you subtract 115 - 45 it equals 70 then you add 70 + 69 which equals 139 then you subtract 237 - 139 it equals 98 which is your answer!

Answers

Answer:

14

Step-by-step explanation:

To evaluate 95 minus 3, four times

95 - 3⁴

95 - (3 * 3 * 3 * 3)

95 - (81)

95 - 81

= 14

Hence, 95 - (3 * 3 * 3 * 3) = 14

1. The top surface of a model building is composed of 2 rectangles and a triangle. Some side lengths of the top surface of the counter are shown. What is the area of the top surface of the model building.

Answers

Answer:

8.625 feets²

Step-by-step explanation:

Based on measurement illustrated in the attached picture :

There are two rectangles and one triangle :

Area of first rectangle :

Area = Length * width

Length = 1.5 ft ; width = 2.5 ft

Area = 1.5 * 2.5

Area = 3.75 ft²

Area of triangle = 1/2 * base * height

Base = 1.5 ; height = 1.5

Area = 1/2 * 1.5 * 1.5

Area = 1.125 ft²

Area of second rectangle :

Area = Length * width

Length = 1.5 ft ; width = 2.5 ft

Area = 1.5 * 2.5

Area = 3.75 ft²

Total area :

(3.75 + 3.75 + 1.125) feets

= 8.625 feets²
