Answer:

QR = 5

Step-by-step explanation:

It's given that ∆ABC ~ ∆QRS. As both of them are similar , the ratio of corresponding sides of both triangles will be proportional to each other.

\frac{AB}{QR}  =  \frac{BC}{RS}  =  \frac{AC}{QS}

AB = 50 ; AC = 60 ; QS = 6

From the above proportion ,

\frac{AB}{QR}=  \frac{AC}{QS}

Putting all the values ,

\frac{50}{QR}  =  \frac{60}{6}

=  >  \frac{50}{QR}  = 10

=  > QR =  \frac{50}{10}  = 5

QS/AC=6/60=1/10

QR/AB=QR/50=1/10

QR=5

SO THAT TRIANGLE ABC IS EQUAL TO TRIANGLE QRS(2SIDES PROPORTIONAL.INC. ANGLE)

The perimeter of a square is to be between 14 and 72 feet, inclusively. Find all possible values for the length of its sides. (&
xxMikexx [17]
We know that the perimeter is the all the sides added up together. Generally, you have p = 2l+2w, where l is length and w is width.

For a square, all sides are of the same length, so you can write p=4x, where x is any side.

If the smallest perimeter is 14, then 14 = 4x, so x is 3.5. If the largest perimeter is 72, then 72 = 4x, so x is 18.

Therefore, you have 3.5 ≤ x ≤ 18.

Please help I don’t get it
lidiya [134]

Answer:

4.718592

Step-by-step explanation:

To get to -14.4 from 18 you multiply 18 x 0.8

Repeat that until you get to the 7th term

18 (1st)

18 x 0.8 = -14.4 (2nd)

-14.4 x 0.8 = 11.52 (3rd)

11.52 x 0.8 = 9.216 (4th)

9.216 x 0.8 = 7.3728 (5th)

7.3728 x 0.8 = 5.89824 (6th)

5.89824 x 0.8 = 4.718592 (7th)
