Answer:
48 square unit
Step-by-step explanation:
For a rectangle, area is given by
A=bh
Where b is base and h is height as shown in the attached diagram
For a triangle, area is given by
A∆=½bh
Given that ½bh=48
Then bh=2*48=96 square units
The overall area is 96 square units.
The area for 1&2 combined will be given by deducting the area of triangle from the overall area
Area is 96-48=48 square units
Answer:
a + c = 30
8a + c = 100
a=10, c= 20
Step-by-step explanation:
cost = 8a + 1c since it is 8 dollars for adult and 1 for child where a is the number of adults and c is the number of children
a+c = 30 since we know that 30 adults and children went
100 = 8a + 1c and it cost 100 dollars
Let c =30 -a
100 = 8a + (30-a)
100 = 7a +30
Subtract 30 from each side
70 = 7a
Divide by 7
10 =a
Then a+c = 30
10+c = 30
c = 30-10
c = 20
Answer:D
Step-by-step explanation:
Answer:
30 inches
Step-by-step explanation:
16^2 + x^2 = 34^2
256 + x^2 = 1156
X^2 = root 900
X = 30
