Answer: 24b-(-27)
Step-by-step explanation:
-3x-8b= 24b
-3x9=-27
For 8, 15.25*18=274.5, 274.5/2= 137.25 or 137 1/4
for 9, 11*13=143, 143/2= 71.5 or 71 1/2
Whether an object will sink or float depends on how the buoyant force compares with the object`s weight. This, in turn, depends on the object`s density.
Answer: B ) The objects probably have different densities.
Answer:
Green paint is made by mixing blue, yellow and white paints in the ratio 2 : 7 : 1. How much blue paint is needed to make 64 litres of green paint? Therefore, the required blue paint = 12.8 litres
Step-by-step explanation:
Answer: Measure angle H = 42°
Step-by-step explanation:
"In a triangle, the measure of the exterior angle is equal to the sum of the measures of the two non-adjacent angles to the exterior angle"
In given we have,
angle E is an exterior angle to triangle DFH
The two non-adjacent angles to angle E are angles D and H
Based on the above rule,
measure angle E = measure angle D + measure angle H
We are given this:
angle E = 87°
angle D = 45°
Substitute with the givens in the above rule and solve for the measure of angle H as follows:
angle E = angle D + angle H
87° = 45° + measure angle H
measure angle H = 87° - 45°
measure angle H = 42°
Hope this helped!
