Quadrilaterals are plane shapes that are bounded by four straight sides. Thus, the required answers to the questions are:

46. True. Other examples include kites, rhombus, etc.

47. False.

46. When a plane shape is bounded by four straight sides of equal or different lengths, it is called a quadrilateral. Examples include trapezium, kite, rhombus, rectangle, square, etc. Each of these examples has individual properties.

Thus the required answer to question 46 is; True. It can be observed that with respect to their individual properties, other quadrilaterals which have a pair of opposite angles to be equal include: kite, rectangle, rhombus, etc.

47. A ray segment is a given line that points or heads in a specific direction. So that the direction in which the ray moves is very important.

Thus in the given question, the required answer is; False. This is because the two given rays are moving in opposite directions. Though the two rays may have the same length of the segment.

Answer:

22.9 ft

Step-by-step explanation:

the height of the wall that reached by the ladder = √ (25²-10²)

=√(625-100)

=√525

= 22.9 ft

Which expression represents the distance between the points (a, 0) and (0, 5) on a coordinate grid?

Mashcka [7]

$\displaystyle d= \sqrt{(x_1-x_0)^2+(y_1-y_0)^2}$ - d is distance, (x_1,y_1) and (x_0,y_0) two points on a coordinate grid.

In our case :
$(x_1,y_1)=(a,0)\\(x_0,y_0)=(0,5)$

$d= \sqrt{(a-0)^2+(0-5)^2} = \sqrt{a^2+25}$

An artist has completed 1/14 of a painting in 2 weeks. At what rate is she working?

joja [24]

Answer:

Rate = 0.035 per weeks

Step-by-step explanation:

Given that,

An artist has completed 1/14 of a painting in 2 weeks.

We need to find the rate at which she is working. Let the rate is R. It can be calculated by dividing part that is completed and time.

$R=\dfrac{\dfrac{1}{14}}{2}\\\\R=0.035\ \text{per weeks}$

Hence, her rate is 0.035 per weeks.

A computer company wants to determine the proportion of defective computer chips from a day's production. A

ozzi

Answer:

0.12 ± 1.96 * √(0.12(0.88) / 100)

Step-by-step explanation:

Confidence interval :

Phat ± Zcritical * √(phat(1 -phat) / n)

Phat = 12/100 = 0.12

1 - phat = 0.88

Zcritical at 95% = 1.96

Hence, we have :

0.12 ± 1.96 * √(0.12(0.88) / 100)

0.12 ± 1.96 * 0.0324961

0.12 ± 0.0636924

Lower boundary = (0.12 - 0.0636924) = 0.0563

Upper boundary = 0.12 + 0.0636924 = 0.1837
