Answer:
400/81 cm²
Step-by-step explanation:
FE : DC
1 : 3
Since area ABCD = 400
s² = 400
s = 20
FE = ⅓(20) = 20/3 cm
IH : FE
1 : 3
IH = ⅓(20/3) = 20/9 cm
Area of HIJK:
(20/9)² = 400/81 cm²
Answer:
EBCG
Step-by-step explanation:
1) 50 - 87 = 23
2) 12 - 24= 288
3) 38.25 + 11.75= 50
4) 7 divided by 168= 24
(11*5)+(4*10)=95
11+4=15
Both are equal to the constraints of the word problem and there for justified.
Answer:
Only table C shows proportional relationship
Step by Step Explanation:
Given
Tables A, B an C
Required
Which table shows proportional relationship?
In table A .
x = 2 and y = 20
k = 20/2
k = 10
Also, x = 12, y = 132
k =. 132/12.
k = 11
Both values of k are not equal.
Hence, the table is not proportional
In table B
x = 5 and y = 20
k = 20/5
k = 4
Also, x = 7, y = 30
k =. 30/7
k = 4.29
Both values of k are not equal.
Hence, the table is not proportional
In table C
x = 9 and y = 90
k = 90/9
k = 10
Also, x = 14, y = 140
k =. 140/14
k = 10
Also, x = 24, y = 240
k =. 240/24
k = 10
All values of k are equal.
Hence, the table is proportional
Answer: $6.66
Explanation:
3.70 multiplied by 0.80 = 2.96.
3.70 + 2.96 = $6.66
