It is easier to write the equivalent ratios first, then use that information to find the missing values.
3. ratio: cars/trucks = 3/5, or trucks/cars = 5/3. Missing value: 6/3*5 = 10.
4. ratio: TVs/Computers = 2/7, or Computers/TVs = 7/2. Missing value: 21/7*2 = 6.
Answer:
0.6
Step-by-step explanation:
Answer:
A = 72°
B = 108°
Step-by-step explanation:
5y - 3 = 3y + 27
5y - 3y = 27 + 3
2y = 30
y = 30/2
y = 15
A = 5y - 3
A = 5(15) - 3
A = 75 - 3
A = 72°
A + B = 180°
72° + B = 180°
B = 180° - 72°
B = 108°
Answer:
The area of the triangle is 40cm^2
Step-by-step explanation:
Calculate the area of a triangle using the equation: 1/2hb
Look at the attached picture and the equation should make sense.
You can use 8cm and 10cm.
8*10 = 80
1/2(80) = 40
So, the area of the triangle is 40cm^2
