58,000,000 km.
5.8 × 10⁷ Km
0.0025 cm
2.5 × 10⁻³ cm
5.8 × 10⁷ Km > 2.5 × 10⁻⁸
Answer:
1) x≥6
--------------------------------------
--------------------------------------
2) h > 20
Mark worked more than 20 hours.
Step-by-step explanation:
1) -20x+18≥-102
-20x≥-102-18
-20x≥-120
Dividing -20 both side
≥
x≥6
--------------------------------------
--------------------------------------
2) 14h + 25 > 305
14h > 305-25
14h > 280
Dividing 14 both side

h > 20
Mark worked more than 20 hours.

Answer: H = 3
Step-by-step explanation:
h=2(A
/a+b) A= area, a= one of the bases, b= other base
2(18/5+7)
The variation equation is qr = 25
<h3>How to determine the equation?</h3>
An inverse variation is represented as:
qr = k
Where k is the constant of variation
When q = 10 and r =2.5, we have:
k = 10 * 2.5
Evaluate
k = 25
Substitute k = 25 in qr = k
qr = 25
Hence, the equation is qr = 25
