Answer:
0.80
Step-by-step explanation:
The garden area is 120 ft^2 and the yard area 150 ft^2.
The probability that a single seed will land in the garden is thus:
120 ft^2
------------ = 4/5 = 0.80
150 ft^2
Answer:
0.5km/h
Step-by-step explanation:
Assume lake has no current.
.
V=distance / time
V=39km / 3h
V=13km/h
In water Assume boat used same power travelling
V=35km / 2h
V= 12.5km/h
Current is the difference 0.5km/h

Answer:
question 3.3 Answer: Angle 3
question 3.4 Answer: ABD and DBC are complementary angles
question 3.5 Answer: x is 7 degrees (first answer option)
Step-by-step explanation:
First question:
Recall that suplementary angles are those whose addition gives 180 degrees. Therefore the supplementary angle to angle 8 is angle 3.
Second question:
Recall that complementary angles are those angles which added give 90 degrees. Therefore, the only correct answer for this question is the third one: ABD and DBC are complementary angles.
Third question:
Notice that the two angles added should render 90 degrees, therefore, their expression should as well add to 90 degrees. Such can be written in equation form as:
( 6 x - 20 ) + (4 x + 40 ) = 90
combining like terms and later solving for x we get:
6 x + 4 x - 20 + 40 = 90
10 x + 20 = 90
10 x = 90 - 20
10 x = 70
x = 7
Therefore x is 7 degrees
To get the area you need to multiply so you would multiply 123° and 18.6 and you would get =2287.8
