Round off 4252 to one significant number

Anettt [7]

4252 rounded is 4000.

Explanation:
When it says "significant number", we assume to round to the nearest thousand. To do this, we look at the hundredths place. If the number in the hundredths place is 1-4, we keep the 4000. If the number is from 1-5, we round up to 5000. Since the hundredths place is 2, we round down to 4000.

Plot and connect the points A(1,-5), B(-4,-3), C(3,-3), and find the area of the triangle it forms.

Dovator [93]

Answer:

7 square units

Step-by-step explanation:

Two of the points are on the horizontal line y = -3, so it is convenient to call that the "base" of the triangle. The length of the base is the difference in the x-coordinates of its end points:

b = 3 -(-4) = 7

The height is measured perpendicular to the base, so is the vertical distance from the line y=-3 to the third point. That distance is the difference between -3 and the y-coordinate of point A:

-3 -(-5) = 2

The triangle has a base of length 7 and a height of 2. Its area is ...

A = 1/2bh

A = 1/2(7)(2) = 7 . . . . square units

lan ran 24 laps in a charity run and then walked 0.2 kilometer to the presentation table the total; distance lan traveled was 29

QveST [7]

Answer:

Step-by-step explanation:

1.225km is equal to each laps

Step-by-step explanation:

Since Kristy total distance traveled = 29.6km

And Kristy ran 24 laps and later walk 0.2km. it simply implies that

Total distance traveled = distance covered running + distance covered walking

Since we know that

Total distance traveled = 29.6km

distance covered running = 24 laps

distance covered walking = 0.2km

Distance covered running in km = total distance traveled - distance covered walking

Distance covered running in km = 29.6km - 0.2km = 29.4km.

To now find the distance for each lap.

Since we have:

Distance covered running in km = 29.4km.

Distance covered running in lap = 24 laps

i.e

24 laps = 29.4km

1 lap = x

Use cross-multiple

24 laps * x = 29.4km × 1 lap

x = 29.4km / 24

x = 1.225km

Therefore

1.225km is equal to each laps.
