scale factor = 1.5

Answer:

side DE / FD = 9 / x

sides BC / AC = 6 / 7

ratios are the same

therefore side FD = 10.5

side AB = 8

scale factor = 12 / 8 = 1.5 or 3/2

elise takes 12 minutes to rake up and bag a pile of leaves her sister katherine takes twice as long, how many minutes would it t
Ymorist [56]

Answer:

80 minutes

Step-by-step explanation:

Rate and Time are inverses of each other

First,

Elise Time = 12

and

Katherine Time = 2 * 12 = 24

Their rates would be (inverses):

Elise Rate = 1/12

Katherine Rate = 1/24

Together their rate is 1/12 + 1/24 = 3/24

Now, the inverse of this rate would be the time it takes to complete 1 bag together, that is:

(3/24) ^ -1 = 24/3 = 8 minutes

So, 10 bags would take them:

8 * 10 = 80 minutes

M is the midpoint of segment GR. G has coordinates (11,-5) and M is (4,-4) Find the coordinates of R
7nadin3 [17]

Answer:

  • (3, -3)

Step-by-step explanation:

<u>Given:</u>

  • G = (11,-5)
  • M = (4,-4)
  • R = ?

<u>Solution</u>

  • R(x, y)

<u>As per midpoint formula;</u>

  • 4 = (11 + x)/2  ⇒ x + 11 = 8 ⇒ x = 3
  • -4 = (-5 + y)/2 ⇒ y - 5 = -8 ⇒ y = -3
  • R = (3, -3)

El perímetro de un rectángulo es 58 y su base excede en 10 a su ancho, ¿Cuánto mide la base? AYUDAAAA
kobusy [5.1K]

Answer:

The base is 19.5.

Step-by-step explanation:

The given question is, "The perimeter of a rectangle is 58 and its base exceeds its width by 10, how long is the base?"

Perimeter = 58

Base, l = 10+b

The perimeter of a rectangle is :

P = 2(l+b)

58 = 2(10+b+b)

29 = (10+2b)

29-10 = 2b

19 = 2b

b = 9.5

Base, l = 10 + 9.5

= 19.5

Hence, the base is 19.5.
