The amount of temperature decreased is :

320 - 280 = 40

The percentage of temperature decreased is :

40 / 320 x 100 % = 12.5 %

The answer is option B. 12.5 %

hope this helps

Answer:

\large\boxed{x=26}

Step-by-step explanation:

\text{The angle}\ x^o\ \text{and}\ 64^o\ \text{together from both sidesr form a right angle.}\\\text{Therefore we have the equation:}\\\\x^o+64^o=90^o\qquad\text{subtract}\ 64^o\ \text{from both sides}\\\\x^o+64^o=90^o-64^o\\\\x^o=26^o

AB = 15, BC = 10, and CD= 7. Find the length DA.
harkovskaia [24]

Answer:

  451. No, the angles are wrong.

Step-by-step explanation:

450. AB = 15, BC = 10, and CD= 7. Find the length DA.

  This cannot be done without additional information about the sort of figure that ABCD is. If these are points on a line segment, we need to know their order. If these are points on a quadrilateral, we need to know its description in more detail.

If these are points ordered ABCD on a line, then AD = 15+10+7 = 32.

__

451. See the attached figure. BPQD is not a parallelogram: BCQ is not a straight line. (The internal angles of a pentagon are 108°, but would need to be 120° for BCQ to be a straight line, making BP parallel to DQ.) Instead, BPQD is an isosceles trapezoid.

Can someone please explain how to find x and y I don’t understand this at all
Sloan [31]

3y is the supplement of 141 so that means 3y+140=180 so y is 13.33. Since they give you 68, 68+13.33+x=180. So 81.33+x=180 and x=98.66.
