6 0

Answer:

  • D. 1/4 and 9/36

Step-by-step explanation:

If two ratios make a proportion then it can be shown as:

  • a/b = c/d ⇒ ad = bc

Let's verify the answer choices with this method

A. 1/4 and 5/25

  • 1*25 = 4*5
  • 25 = 20, incorrect, not a proportion

B. 1/4 and 7/24

  • 1*24 = 4*7
  • 24 = 28, incorrect, not a proportion

C. 1/4 and 10/48

  • 1*48 = 4*10
  • 48 = 40, incorrect, not a proportion

D. 1/4 and 9/36

  • 1*36 = 4*9
  • 36 = 36, correct, this is a proportion

Elena-2011 [213]

Camille spent 22 minutes and 30 seconds opening presents.

Since Camille had a very fun birthday party with lots of friends and family attending, and the party lasted for 3 hours, and she and her friends played games for 3/8 of the time, ate pizza and cake for 50% of the time , and spent the remainder of the time opening presents, to determine the amount of time spent opening presents the following calculation must be performed, posing the following linear equation:

Total time - time spent on other activities = time spent opening presents

  • 3 - (3 x 3/8) - (3 x 0.5) = X
  • 3 - 1.125 - 1.5 = X
  • 3 - 2.625 = X
  • 0.375 = X

  • 1 = 60
  • 0.375 = X
  • 0.375 x 60 = X
  • 22.5 = X

Therefore, Camille spent 22 minutes and 30 seconds opening presents.

How in the world do I answer this problem??​
galben [10]

Answer:

22

Step-by-step explanation:

ST is y and SU is 2y-4.

Note that SU = ST + TU = y + 18

So we have 2y - 4 = y + 18

2y - 4 = y + 18

2y      = y + 22

y        = 22

So ST is 22.

What is the area of the figure? Use 3.14 for π. Round to the nearest hundredth if necessary.
vfiekz [6]

Answer:

81.12 cm²

Step-by-step explanation:

The area for a semicircle can be figured with this formula: (πr²)/2. The triangle's area formula is bh/2.

(3.14 * 4²)/2 + (14 * 8)/2 <em>(Work the operations in parentheses first.)</em>

(3.14 * 16)/2 + 112/2

50.24/2 + 112/2 (<em>Divide 50.24 by 2. Do the same for 112.)</em>

25.12 + 56 (<em>Add 25.12 & 56.)</em>

81.12 cm²

The area of the figure is 81.12 cm².
