1/4w + 3 the answer has to be 20 characters long so ignore this
Answer:
m ∠RMK = 51°
Step-by-step explanation:
m ∠JMK = m ∠RMK + m ∠JMR
10x + 19 = 7x - 26 + 6x + 12
10x +19 = 13x -14
19 = 3x -14
33 = 3x
11 = x
m ∠RMK = 7(11) - 26 = 51°
m ∠JMR = 6 (11) + 12 = 78
Answer:
9 miles
Step-by-step explanation:
use Pythagoras theorem
15 squared - 12 squared = 81
square root of 81 is 9
Bob's Bikes
260 × 0.2 = 52
260 - 52 = 208
208 × 2 = $416.00
Walt's Wheels
300 × 0.6 = 180
300 - 180 = 120
120 × 2 = $240.00
Carson's Cycles
310 × 0.1 = 31
310 - 31 = 279
279 × 2 = $558.00
(i can't read what it says for $50, comment below if it makes a difference, i'll edit)
Tino's Transportation
260 ÷ 2 = 130
260 + 130 = $390.00
B) Walt's Wheels provides the lowest price for two bicycles.
We have to calculate the suface of the four walls and the ceiling.
Surface of the four walls=2(10 ft * 10ft ) + 2(12 ft * 10 ft)=200 ft² + 240 ft²=
=440 ft²
Surface of the ceiling=10 ft * 12 ft=120 ft²
Total surface=440 ft² + 120 ft²=560 ft²
Now, we have to caluclate the number of gallons of paint.
1 gallon------------------------400 ft²
x----------------------------------560 ft²
x=(1 gallon * 560 ft²) / 400 ft²=1.4 gallons.
answer: Ryan need to paint all four walls and the ceiling 1.4 gallons.
