K= 1/12
perimeter of doll house= 36 inches
:. length of doll house= 36inches / 4
= 9 inches
length of actual= length of doll house x k(inverse)
:. actual lenght= 9 inches x 12/1
= 108 inches
To find the midpoint, add both x values together and divide by two and then add both y values together and divide by two.
Midpoint X = (-3 +4)/2 = 1/2
Midpoint y = (-4 + -1)/2 = -5/2
Midpoint = (1/2, -5/2)
Answer:
your answer should be 3 1/4
Step-by-step explanation:
Answer:
1.9
Step-by-step explanation:
Gabrielle uses 7.6 pints of blue and white paint to paint her bedroom
1/4 of the paint is blue paint
Therefore the amount of white paint she used to paint her bedroom can he calculated as follows
= 1/4
= 0.25×100
= 25%
25/100×7.6
= 2.5 × 7.6
= 1.9
Hence 1.9 pints of white paint was used to paint the room
Answer:
∠1 - 40°
Step-by-step explanation:
∠1 - 40°
b/c it's a right triangle and we have two angles given, 50° and 90°. Add them and subtract by 180° and get 40°.
∠2 - 140°
b/c an exterior (outside) angle is equal to the two most isolated / farthest angles added. The two most is angles are 105° and 35°, add them and get 140°.
∠3 - 40°
b/c ∠'s 1 and 3 are vertical angles meaning they're equal so since ∠1 is 40°, so is ∠3.
∠4 -
b/c ∠' s 2 and 4 are vertical angles meaning they're equal so since ∠2 is 140°, so is ∠4.
∠5 - 35°
b/c we have two angles, 105° and 40°. Add them and subtract by 180° and get 35°.
