The Floyds have considered three options to ensure they have at least $1,375 saved for their trip.

ANTONII [103]

I am guessing you are talking about Option 3. They start with $125. So they times it by 1.25 as we are using the multiplier method. So in the First month, it will be 156.25. Second it will be 195.3125. So in August it will be $476.837157. Of couse round it and you will get $476.84.

I believe there is a more efficent way of doing this but I have forgotten.

Express the given expanded numeral as a Hindu-Arabic numeral. (8x102) +(4x10)(2x1)

Marysya12 [62]

Answer:

The Hindu-Arabic numeral form of the given expanded numeral is 842.

Step-by-step explanation:

The given expanded numeral is

$(8\times 10^2)+(4\times 10)+(2\times 1)$

We need to express the given expanded numeral as a Hindu-Arabic numeral.

According to Hindu-Arabic numeral the given expanded numeral is written as

$(8\times 10^2)+(4\times 10)+(2\times 1)=(8\times 100)+(4\times 10)+(2\times 1)$

On simplification we get,

$(8\times 10^2)+(4\times 10)+(2\times 1)=(800)+(40)+(2)$

$(8\times 10^2)+(4\times 10)+(2\times 1)=842$

Therefore the Hindu-Arabic numeral form of the given expanded numeral is 842.

Write an equation of the ellipse centered at the origin given its vertex and co vertex

jolli1 [7]

Answer:

$\dfrac{x^2}{49}+\dfrac{y^2}{25}=1.$

Step-by-step explanation:

The equation of the ellipse is

$\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1.$

If the vertex of the ellipse is at point (-7,0), then a=7.

If the co-vertex of the elllipse is at point (0,-5), then b=5.

The equation of the ellipse is

$\dfrac{x^2}{7^2}+\dfrac{y^2}{5^2}=1,$

$\dfrac{x^2}{49}+\dfrac{y^2}{25}=1.$
