Answer:

  1.  42 square feet

  2.  3192 square cm

Step-by-step explanation:

In general, the shaded area is the area of the bounding geometry less the unshaded area inside that boundary. In each case here, the bounding geometry is a rectangle, and the unshaded area is some portion of a circle. The rectangle and circle area formulas are used.

__

1. shaded area = square area - circle area

  shaded area = (14 ft)² = π(7 ft)² = (196 -49π) ft²

We will use 22/7 for pi, so the shaded area is ...

  (196 -49(22/7)) ft² = (196 -154) ft²

  shaded area = 42 ft²

__

2. Here, the bounding box is a rectangle, and we only need to subtract a semicircle.

  shaded area = (50 cm)(70 cm) -1/2(22/7)(14 cm)² = 3500 cm² -308 cm²

  shaded area = 3192 cm²

Suppose there are 10 green, 8 brown, 3 yellow, 8 blue, and 6 red candies in a bag. If you randomly pick out one candy, what is t
REY [17]

Answer:

<h2>9/35, 0.257 or 25.7%</h2>

Step-by-step explanation:

The basic and simple way to calculate the probability of an event happening is by using this equation:

<h2>Number of desired outcomes</h2><h2>------------------------------------------------- = Probability </h2><h2>Number of all possible outcomes</h2><h2 />

Our desired outcomes are picking either red or yellow candies. The number of desired outcomes in this case is the total number of red and yellow candies. 6 red + 3 yellow = 9

Number of desired outcomes = 9

Number of all possible outcomes in this case is the total number of candies in the bag. 10 green + 8 brown + 3 yellow + 8 blue + 6 red = 35

Number of all possible outcomes = 35

Use the formula and we get that the probabbility of drawing out a yellow or red candy is: 9/35, 0.257 or 25.7% (those are 3 different ways to write the probability)

4x10+(8x1/10)+(2x1/1000) in standard Form
CaHeK987 [17]

Answer:

40.802

Step-by-step explanation:

4x10+(8x1/10)+(2x1/1000)  is found by calculating the three different terms (with different powers of 10) separately and then adding these results together:

4*10 = 40

8*(1/10) = 0.8

2*(1/1000) =.002

Summing up these results, we get:

40.802

aivan3 [116]

Answer:

A: Angle J

Step-by-step explanation

If the two triangles are congruent then their corresponding angles are also congruent. This means that angle P is congruent to angle J, angle Q is congruent to angle K and angle R is congruent to angle L. Hope this helps :D
