Answer:

<h3>48 min to complete 8Km</h3>

Step-by-step explanation:

Usain runs 5km in --- 30 minutes

$also \: \: speed = \frac{distance \: covered}{time \: taken \: }$

<h2>Usain's speed = 5km/30min</h2>

So, Usain takes 6 min to complete 1 km

So , to cover 8km he will take = 8 × 6min

= 48min

What are the coordinates of the image rectangle for a scale factor of 3 if the center of dilation is the origin?

Ksju [112]

Answer: Choice B)

Explanation:

You mentioned there isn't a diagram to go with this, but I'm assuming that this problem is referring to a previous problem you posted. In that problem, it mentions that point W is at (1,-2). If we apply the scale factor 3, then we're tripling each coordinate. That means x = 1 becomes x = 3, and y = -2 becomes y = -6

We can write it like this:

(1,-2) ---> 3*(1, -2) = (3*1, 3*(-2) ) = (3, -6)

Only choice B has W'(3,-6) so this is likely the final answer.

If we apply this dilation to every point, then that effectively makes quadrilateral W'X'Y'Z' to be three times longer and taller than compared to quadrilateral WXYZ. In other words, its side lengths are 3 times longer.

Points S,U, and T are the midpoints of the sides of PQR. Which statements are correct ? 1/2QP=UT 1/2TS=RQ SU=PR SU||RP UT=RP

cricket20 [7]

Answer:

$\frac{1}{2} QP = UT$

Step-by-step explanation:

GIVEN : In ΔPQR

S is the mid point of QP

U is the mid point of PR

T is the mid point of QR

Solution :

i) is true i.e $\frac{1}{2} QP = UT$

Refer the attached file

By mid segment theorem i.e. In a triangle, the line joining the midpoints of any two sides will be parallel to the third side and that same line joining the midpoints is also half of length of third side .

UT is the line joining the two mid points . So, by theorem given above UT is parallel to PQ and 1/2QP=UT.

So, (i) statement is true i.e. $\frac{1}{2} QP = UT$
