Hello! I can help you!

12. Okay. 16 1/5 is 16.2 in decimal form. Let’s subtract both numbers. 19.8 - 16.2 = 3.6. Paloma is 3.6 seconds faster than Savannah in the 100m dash.

13. Two lengths that are within the given span of 0.08 and 0.4 are 0.22 and 0.17. 0.22 as a fraction in simplest form is 11/50 and 0.17 as a fraction in simplest form is 17/100.

Skylar wanted to show the proportional relationship between the dollar value of the original investment, x, and its value after
suter [353]

After checking the information of the table, it is to notice that the table fulfills the behavior of a <em>direct</em> relationship described by the <em>linear</em> equation y = 0.9 · x. #SPJ1

<h3>How to analyze a relationship between the two variables</h3>

Let be <em>x</em> and <em>y</em> the <em>original</em> investment and the value after applying the change, both in monetary units. A <em>direct</em> relationship is observed by following this model:

y = (1 + r/100) · x     (1)

Where <em>r</em> is change rate, in percentual units.

After checking the information of the table, it is to notice that the table fulfills the behavior of a <em>direct</em> relationship described by the <em>linear</em> equation y = 0.9 · x. #SPJ1

<h3>Remark</h3>

The table of the <em>change</em> in investment with respect to <em>initial</em> investment is missing and is now introduced below:

<em>(x₁, y₁) =</em> (75, 7.5), <em>(x₂, y₂) =</em> (100, 10), <em>(x₃, y₃) =</em> (200, 20), <em>(x₄, y₄) =</em> (300, 30), <em>(x₅, y₅) =</em> (400, 40)

Mhanifa please help! Solve for the unknown in each triangle. Round to the nearest tenth.
Scilla [17]

Answer:

(D)

<u>Use the law of sines:</u>

  • 13 / sin x = 12 / sin 67°
  • sin x = 13 sin 67° / 12
  • sin x = 0.997
  • x = arcsin (0.997)
  • x = 85.6°

(E)

<u>Find the third angle:</u>

  • 180° - (48° + 61°) = 71°

<u>Use the las of sines:</u>

  • x / sin 61° = 21 / sin 71°
  • x = 21 sin 61° / sin 71°
  • x = 19.4 cm
