Estimate the sum of 299 and 388
Svetllana [295]

For this case we have the following numbers:

299

388

Let's round up each of the numbers to the nearest hundred,

We have then:

299 = 300

388 = 400

We note that now we have two numbers whose approximation is easier to add.

We have then:

300 + 400 = 700

Answer:

The sum of 299 + 388 is approximately:

700

!TWELVE POINTS + BRAINLIEST ANSWER! Write the equation for an ellipse with y intercepts (0,-3) and (0, 3) and major axis of leng
Mandarinka [93]

Answer:

x²/25 + y²/9 = 1  or 9x² + 25y² = 225

Step-by-step explanation:

We have two points which is y intercepts (0,-3) and (0,3).

We know that the major axis is 2a and secondary axis is 2b

These two points are vertical top of the ellipse which they give us value of half secondary axis  b = 3

The length of major axis is 2a = 10 => a = 10/2 = 5 => a = 5

The equation of the ellipse is:

x²/a² + y²/b² = 1  or b²x² + a²y² = a²b²

When we replace value of a and b we get:

x²/5² + y²/3² = 1  or 3²x² + 5²y² = 5² · 3²    and finally

x²/25 + y²/9 = 1  or 9x² + 25y² = 225

God with you!!!
