Ginny is cutting construction paper into rectangles. She needs to cut one rectangle that is 16 inches × 13 1/4 inches. She needs

kykrilka [37]

Answer:

317.92 square inches

Step-by-step explanation:

Rectangle A:

Area of a rectangle = length × width

Length = 16 inches

Width = 13 1/4 inches = 53/4 inches

Area of a rectangle = length × width

= 16 inches × 53/4 inches

= (16 * 53) / 4 inches²

= 848/4

= 212 square inches

Rectangle B:

Area of a rectangle = length × width

Length = 10 1/3 inches = 31/3 inches

Width = 10 1/4 inches = 41/4 inches

Area of a rectangle = length × Width

= 31/3 inches × 41/4 inches

= (31 * 41) / (3 * 4) square inches

= 1271 / 12

= 105.92 square inches

How many total square inches of construction paper does Ginny need?

total square inches needed = Area of rectangle A + Area of rectangle B

= 212 square inches + 105.92 square inches

= 317.92 square inches

Find the Value of Sin A rounded to the nearest hundredth, if necessary.

leonid [27]

Step-by-step explanation:

In trigonometry, the law of sines is an equation that relates the length of the sides of a triangle (any type of triangle) to the sines of its angles. This is expressed mathematically as

$\displaystyle\frac{a}{\sin \alpha} \ = \ \displaystyle\frac{b}{\sin \beta} \ = \ \displaystyle\frac{c}{\sin \gamma}$ ,

where $a$ , $b$ , and $c$ are the lengths of the sides of the triangle and $\alpha$ , $\beta$ , and $\gamma$ are the opposite angles (as shown in the figure below). Likewise, the law is sometimes written as it reciprocals,

$\displaystyle\frac{\sin \alpha}{a} \ = \ \displaystyle\frac{\sin \beta}{b} \ = \ \displaystyle\frac{\sin \gamma}{c}$ .

Therefore,

$\displaystyle\frac{\sin A}{BC} \ = \ \displaystyle\frac{\sin B}{AC} \\ \\ \\ \sin A \ = \ \displaystyle\frac{\sin B \ \times \ BC}{AC} \\ \\ \\\sin A \ = \ \displaystyle\frac{\sin \left(90^{\circ}\right) \ \times \ \sqrt{\left(10\right)^{2} \ - \ \left(\sqrt{78}\right)^{2}}}{10} \\ \\ \\ \sin A \ = \ \dsiplaystyle\frac{\sqrt{22}}{10} \\ \\ \\ \sin A \ = \ 0.47 \ \ \ \ (\text{nearest hundredth})$

Alternatively, you can solve this question using the definition of the trigonometric function sine. For the angle $\theta$ in the figure below,

$\sin \theta \ = \ \displaystyle\frac{\text{opposite}}{\text{hypothenuse}}$ .

Therefore,

$\sin A \ = \ \displaystyle\frac{BC}{AC} \\ \\ \\ \sin A \ = \ \displaystyle\frac{\sqrt{\left(10\right)^{2} \ - \ \left(\sqrt{78}\right)^{2}}}{10} \\ \\ \\ \sin A \ = \ \displaystyle\frac{\sqrt{22}}{10} \\ \\ \\ \sin A \ = \ 0.47 \ \ \ \ (\text{nearest hundredth})$

iragen [17]

Answer:

B

Step-by-step explanation:

There is a pattern. Subtract input from output and it is 11. So, if 11 is the pattern. subtract 51 from A,B,C, and D.Till one of them has the number 11 as answer. 51- 40=11. 40 = B
