Answer:
para el primer dibujo seria 1/12
para el segundo dibujo seria 1/16
para el tercer dibujo seria 1/10, pero tengo dudas con esta porque no se ve toda la figura.
Step-by-step explanation:
Answer:
48.56 cm
Step-by-step explanation:
The rectangle: 10+10+8+8
= 36cm
The half circle: 1/2 πd
=1/2x3.14X8
= 12.56
So, the total perimeter will be- 36+12.56
=48.56
Mark me brainliest plss :)) I worked hard for the ans
Answer:
m∠Q = 121°
m∠R = 58°
m∠S = 123°
m∠T = 58°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Create an expression for the sum of all the angles and equate it to 360, then solve for x:
∠Q + ∠T + ∠S + ∠R = 360
⇒ 2x + 5 + x + 2x + 7 + x = 360
⇒ 6x + 12 = 360
⇒ 6x = 360 - 12 = 348
⇒ x = 348 ÷ 6 = 58
So now we know that x = 58, we can calculate all the angles:
m∠Q = 2x + 5 = (2 x 58) + 5 = 121°
m∠R = x = 58°
m∠S = 2x + 7 = (2 x 58) + 7 = 123°
m∠T = x = 58°
Answer:
The percentage error in the prediction = 10.20%
Step-by-step explanation:
A sports broadcaster predicts a basketball team will score 88 point me in the next game.
If the team has actually scored 98 points we have to find the percentage error in the broadcaster's prediction.
The deviation of the prediction from the actual value = 98 - 88 = 10.
The formula for finding error percentage = 
= 
= 10.20 %
The percentage error = 10.20%
