Answer:
350 inches
Step-by-step explanation:
The 7 "ratio units" represent 490 inches, so each represent 490/7 = 70 inches. Then 5 "ratio units" will represent 5×70 inches = 350 inches.
smaller perimeter : larger perimeter
= 5 : 7
= (350 inches) : (490 inches)
Answer:
x=27.5
FG=72.5
GH=60
HF=47.5
Step-by-step explanation:
Sum of angles in a triangle=180
Therefore, FG+GH+HF=180
Substituting the values we have,
(3x - 10) + (2x+5) +(x+20) = 180
Collecting like terms
3x+2x+x = 180 +10 - 5 - 20
6x = 165
X= 27.5
FG = (3x - 10) = 3(27.5) - 10
FG= 72.5
GH= (2x+5) = 2(27.5)+5
GH=60
HF= x+20 =27.5+20
HF=47.5
Answer:
Step-by-step explanation:
Evaluating the numerator and denominator before evaluating
Using the rule of exponents
⇔ 
, 
= 1
Thus
y² ← substitute values into expression
= 
× 4² = 
× 16 = 
and denominator
= 1 × 4³ = 1 × 64 = 64
Now dividing
÷ 64
= × 
( cancel 16 and 64 )
= 
=
