Tony worked 4 2/3 hours on his science project. Sonia worked 1 1/4 times as long on her science project as Tony did.For how many

kherson [118]

To find how many hours Sonia work on her science project,we can multiply the working hours of Tony by the times Sonia did:

$4 \frac{2}{3} \times 1 \frac{1}{4} \\ = \frac{14}{3} \times \frac{5}{4} \\ = \frac{70}{12} \\ = 5 \frac{10}{12} \\ = 5 \frac{5}{6}$
Therefore Sonia work on her science project for 5 5/6 hours.

Hope it helps!

he length, l , of a rectangle is 80% of its width, w . Write an equation that represents the length of the rectangle if its widt

Minchanka [31]

In this item, we are given that the length of the rectangle is equal to 80% of its width and that its width is equal to 95 inches. The length can be calculated by multiplying the decimal equivalent of the given percentage and the width. That is,
l = 0.8w

If we are to substitute the given value,
l = 0.8(95 inches) = 76 inches

Hence, the answer is that the length is 76 inches.

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

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

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