Gina is cutting construction paper into rectangles for a project. She needs to cut one rectangle that is 12 inches by 14 1/4 inc
Fittoniya [83]

Answer:

278.63 square inches

Step-by-step explanation:

Gina needs to cut two types of rectangles.

Dimensions of one rectangle is given as,

Width = 12 inches

Length = 14\frac{1}{4} = \frac{57}{4} inches

So, the area of this rectangular paper will be

Area = width × length = 12\times \frac{57}{4} = 171 inches²

Dimensions of the other rectangular paper has been given as

Width = 10\frac{1}{4} = \frac{41}{4} inches

Length = 10\frac{1}{2} = \frac{21}{2} inches

So, the area of this rectangle will be

Area = width × length = \frac{41}{4} \times \frac{21}{2} = 107.63 inches²

Thus the total area she need to cut = 171 + 107.63 = 278.63 square inches.

Identify the graph of the equation. What is the angle of rotation for the equation?
borishaifa [10]

Answer:

d. parabola, 0°

Step-by-step explanation:

y² + 8x - 0

y² = -8x

Where x = cos t  ,  y = sin t

Sin² t = -8 Cos t

1 - Cos² t = -8 Cos t

- Cos² t + 8 Cos t + 1 = 0

t = 2лπ ± (3 + √10) , л∈Z

3^3 . x^2- 25 divided by 5 when x= 0.6
Alenkasestr [34]

Hey there!

3^3 * x^2 - 25 / 5

= 3^3 * 0.6^2 - 25 / 5

= 3 * 3 * 3 * 0.6 * 0.6 - 25 / 5

= 9 * 3 * 0.6 * 0.6 - 25 / 5

= 27 * 0.36 - 25 / 5

= 9.72 - 25 / 5

= 9.72 - 5

= 4.72


Therefore, your answer is: 4.72


Good luck on your assignment & enjoy your day!
