<u>Statement</u><u>:</u>

PQRS is a rhombus with PQ = (9b - 5) and QR = (3b - 0.8) meters. S is the midpoint of RT.

<u>To </u><u>find</u><u> out</u><u>:</u>

The length of RT.

<u>Solution</u><u>:</u>

  • There is a property of a rhombus that all sides of the rhombus are equal.

  • So, PQ = QR = RS.

  • Therefore, 9b - 5 = 3b - 0.8
  • or, 9b - 3b = -0.8 + 5
  • or, 6b = 4.2
  • or, b = 4.2 ÷ 6 = 0.7 m

  • Therefore, the length of RS
  • = 9b - 5
  • = 9(0.7) - 5 m
  • = 6.3 - 5 m
  • = 1.3 m

  • S is the midpoint of RT.
  • Hence, TS = RS = 1.3 m

  • Therefore, the measure of RT
  • = TS + RS
  • = (1.3 + 1.3) m
  • = 2.6 m

<u>Answer</u><u>:</u>

RT = 2.6 meters

Hope you could understand.

If you have any query, feel free to ask.

Answer: 2.6

Step-by-step explanation:

PQ = QR (because it’s a rhombus), so


9b - 5 = 3b - 0.8

b = 0.7


And RS = PQ (again because rhombus), so RS = 9b - 5 = 1.3. Since RT is twice RS, we have


RT = 2(1.3) = 2.6.

The diameter of the circle is 10 units what is the radius of the circle
gayaneshka [121]

Answer:

Radius is 5 units

Step-by-step explanation:

The radius of a circle will always be 1/2 of the diameter.

This gives the formula:

r=\frac{d}{2}

(substitute known values)

r=\frac{10}{2}

(divide 10 by 2)

r=5

Therefore the radius is five

10 1/16ft + 8 3/8ft +1/2 ft
Whitepunk [10]

Answer:

18 15/16 ft

Step-by-step explanation:

what is the request here ?

to do the additions and bring all to one summary result of ft ?

I base my answer on this assumption.

10 1/16 = 161/16

8 3/8 = 67/8

1/2 = 1/2

note let's bring everything to 16th, so that we can actually add them.

161/16

67/8 = 134/16

1/2 = 8/16

161/16 + 134/16 + 8/16 = 303/16 = 18 15/16

cross check :

add all whole numbers first, and then add the remaining fractions too (need to bring them to 16th too).

10 + 8 = 18

1/16 + 3/8 + 1/2 = 1/16 + 6/16 + 8/16 = 15/16

together, 18 15/16

yeah, it is the same.
