How to round 750 to the nearest hundred

Mathematics
1 answer:
Rzqust [24]2 years ago
7 0
The way you round is if it is below 5 you round down and if it is above 5 you round up so in the case of 750 it would go to 800 where if it was 749 it would go to 700

Describe how to draw a line that passes through the origin and has a slope of 3/5
ANEK [815]
The "origin" of a line is simply the points (0, 0)

To draw a line that passes through the origin (0, 0) & has a slope of 3/5, we simply start by drawing a point at (0, 0).

Then, from there, you use the slope to find your next points.

Slope = rise/run

So, 3 is the rise, and 5 is the run.

So, starting from (0, 0), you go up 3 times, and go to the right 5 times. So, (3, 5) is your next point. Just continue doing that and you'll get a line.

~Hope I helped!~

A line with a slope of 8 passes through the points (-1,1) and (0,k). What is the value of k?
Diano4ka-milaya [45]

Answer:

k = 9

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 8

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)

m = \frac{k-1}{0+1} = k - 1 = 8 ( add 1 to both sides )

k = 9

Tossing a regular coin 3 times, what is the probability of getting heads every time? 4)
larisa [96]

The probability of getting heads on the first toss is  1/2 .

Then, the probability of getting heads on the second toss is  1/2 .

Then, the probability of getting heads on the third toss is  1/2 .

The probability of all three things happening is ...

                 (1/2) x (1/2) x (1/2)  =  1/8  =  0.125  =  12.5% .

I need to find the surface area for this one pls help me
Alex

Step-by-step explanation:

so, you got the volume but don't know how to find the surface area ? that is strange for me. what's the problem ?

the surface of a cube or rectangular prism consists of 6 sides that split (for a rectangular prism) into 3 pairs of equal sides :

top and bottom

left and right

front and back

all we need to do is calculate the areas of these 6 rectangles and add them up. that's it.

in our case

top and bottom : 5×4 × 2 = 20×2 = 40 in²

left and right : 4×4 × 2 = 16×2 = 32 in²

front and back : 5×4 × 2 = 40 in²

so, in total, the whole surface area of the prism is

40 + 32 + 40 = 112 in²

Find the domain and range of the relation.<br> {(3,-2) (2,1) (-1,0) (1,3)}
svp [43]
The domain of the inverse of a relation is the same as the range of the original relation. In other words, the y-values of the relation are the x-values of the inverse.
