How long does it take to travel 100km at a speed of 80 km/h?

Answers

Answer 1

speed = distance/time,
You can kind of tell that, because the units of speed is km/h ( or m/s, or miles/hour — depending on the situation).

Now if you apply your algebra skills, you might discover that

time = distance/speed

Plug in the data:
time = 100 km / (80 km/h)
After application of algebra skills again you can see that the units will simplify to simply h.
time = 1.25 h

Find the values of x and y. Write your answers in simplest form.

Answers

Step-by-step explanation:

by trigonometry,

cos 30 = x/12√3 =√3/2

→ x=18

sin 30 =y/12√3=1/2

→ y=6√3

The values of x and y are 18 and 10.392 respectively.

What are the right triangles?

The definition for a right triangle states that if one of the angles of a triangle is a right angle - 90º, the triangle is called a right-angled triangle or simply, a right triangle. In the given image, triangle ABC is a right triangle, where we have the base, the altitude, and the hypotenuse. Here AB is the base, AC is the altitude, and BC is the hypotenuse.

Given right triangle

hypotenuse = 12√3

base = x and height = y

angle of base = 30°

cosФ = b/h

cos30 = x/12√3

x = 12√3 x √3/2

x = 18

and sin30 = p/h

sin 30 = p/12√3

p = 1/2 x 12√3

p = 6√3

p = 10.392

Hence the values of x= 18 and y = 10.392.

The scale of this map is 1 inch = 50 miles. The ruler measures the distance between Gary, Indiana, and Traverse City, Michigan, as 3 inches. How many actual miles are between these two cities?

Answers

Answer:

150 miles

Step-by-step explanation:

Given the scale on the map using the conversion factor

1 inch = 50 miles

We are to find the equivalent miles between the cities in miles if the distace is 3inches

3inches = x

Divide both expressions

1/3 = 50/x

Cross multiply

x = 3 * 50

x = 150

Hence the actual distance between these two cities in miles is 150 miles

Answers

Answer:

63 chickens per square mile

Step-by-step explanation:

We are to calculate the average number of chickens per square mile.

Number of chickens = 40×5⁷

Number of square miles = 16×5⁵

The average number of chickens per square mile = 40 × 5⁷/16 × 5⁵

= 3125000/50000

= 62.5 chickens per square mile

Approximately to the nearest whole number is

= 63 chickens per square mile

Therefore,the average number of chickens per square mile is 63 chickens per square mile.

What is the equation, in slope-intercept form, of the line that passes through (0, -2)
and has a slope of -3? (5 points)
O 1) y = -3x - 2
O 2 y=-3x+ 2
O3) y = –2x+3
O 4) y = -2x - 3

Answers

Answer:

Step-by-step explanation:

Slope intercept form is y=mx+b, where m is the slope and b is the y intercept.

We are given a point: (0,-2) and a slope; -3.

we can substitute the numbers into the equation above, with what we know, to find b.

-2=-3(0)+b

multiply

-2=0+b

-2=b

so the y intercept is -2.

Since we know that the slope is -3, and the y intercept is -2, the equation is y=-3x-2

Therefore O1 is your answer

You got this. Just a proportional issue once units of cm and m is converted.

1 meter is 100 centimeters (deci is 10, centi is 100, milli is 1000)

4.5 meter = 4.5 x 100 or 450 centimeters

(450/90)x100= 500%. 4.5 meters is 5 times longer than 90 cm
