Answer:

1) In the given figure opposite sides are Parallel . Hence, it is a parallelogram.

2) Option (1) and (3) are correct.

Step-by-step explanation:

Parallelogram is a two dimensional figure with opposite sides parallel and equal in length and diagonals bisect the angles.

Rectangle is two dimensional figure with opposite sides equal in length and measure of each angle is 90° .

Square is two dimensional figure with all sides equal in length and measure of each angle is 90°.

Rhombus is a two dimensional figure with all sides equal in length and sum of measure of opposite angle is 180°.

Thus, in the given figure opposite sides are Parallel . Hence, it is a parallelogram.

The sufficient condition for a parallelogram to be square is diagonals are perpendicular and diagonals are congruent and all the sides are congruent.

Thus, (1) and (3) are correct.

Suppose an architect draws a segment on a scale drawing with the end points (0,0) and (3⁄4,9⁄10). The same segment on the actual

Kipish [7]

Segment drawn on scale having end points O (0,0) and A $(\frac{3}{4},\frac{9}{10})$ is a line segment.

O A= $\sqrt{[\frac{3}{4} -0]^{2} +[\frac{9}{10} -0]^{2}\\\\$

O A = $= \sqrt{\frac{9}{16}+\frac{81}{100}$

= $\sqrt\frac{549}{400}$

= $\frac{\sqrt{549}}{20}$

Now , the same segment actual structure having end points O'(0,0) and B (30,36) is also a line segment.

O'B= $\sqrt{(30-0)^{2}+(36-0)^{2}$

= $\sqrt{900+1296}$

= $\sqrt {2196}$

= 2√549

$\frac{\text{Actual length}}{\text{Length on scale}}=\frac{OB'}{OA}=\frac{2\sqrt549}{\frac{\sqrt549}{20}}=40$ [Cancelling √549 from numerator and denominator]

So, Actual length = 40 × Length on scale

Which item has a unit rate of $6.50?

marshall27 [118]

Answer:

T-shirts

Step-by-step explanation:

First, find the unit price for caps. Divide 25 by 4, which equals $6.25. Then, divide 20.25 by 3, which equals $6.75. Next, divide 30 by 4, which equals $7.50. Finally, divide 32.50 by 5, which equals $6.50. To t-shirts have a unit rate of $6.50

An airplane needs to reach a velocity of 203.0 km/h to take off. On a 2000 m runway, what is the minimum acceleration necessary

Aliun [14]

Answer:

1.59 m/s²

Step-by-step explanation:

Acceleration = change in Velocity over time. Mathematically it is represented as Δv/Δt

Given values in the question:

Final velocity 203.0 km/h which is equal to (203/3.6)m/s = 56.39 m/s
distance 2000 m
Initial velocity is 0 m/s

To use the equation for acceleration time is needed.

velocity= distance/time

(203/3.6) = 2000/time mltiplying both sides by time

(203/3.6) x time = 2000 making time subject of the formula

time = 2000/(203/3.6)

time = 35.47 seconds

Substituting into the acceleration equation

acceleration =Δv/Δt

=(56.39- 0)/35.47

= 56.39/35.47

=1.59 m/s²

Pls answer ASAP

Alex Ar [27]

Answer:

first answer

Step-by-step explanation:

the first symbols mean : congruent.

the second symbols mean : parallel.

therefore answer option 1 is the direct translation of "if opposite sides of a quadrilateral are congruent, then it is a parallelogram" (= each of the 2 pairs of opposite sides consists of parallel sides).

Evaluate f(x) when x = 6.

BartSMP [9]

Answer:

f(x) = x-6

Step-by-step explanation:

Since x = 6, which is a positive number, the answer should be of f(x) = x-6.

When x = -6, which is a negative number, then the answer should be f(x) = x+6.
