Answer:
Option(D)
Step-by-step explanation:
Diameter of the Sun (S) = 1.4 × 10⁶ km
Diameter of a planet mars (M) = 7000 km
≈ 7.0 × 10³ km
Ratio of the diameter of the Sun to the diameter of Mars
= 
= 
= 
= 
= 
Option (D) will be the correct option.
Answer:
it would take 20 miles and cost 10 dollars.
Step-by-step explanation: Like up the equations so that 50x=40x+200. When you solve for x (number of miles) you find that x=20. Use 20 in either equation (0.5x or 0.4x+2) to get 10 (total cost).
Answer:
27.74cm^2
Step-by-step explanation:
area of circle: 3 times 3 times pi = 28.26cm^2
area of square: 8 times 7 = 56cm^2
subtract area of circle from square
56-28.26=27.74cm^2
Answer:
3
Step-by-step explanation:
We know that a acute angle is a angle whose measure is less than 90°.
Now we know that the sum of all the angles of a triangle is 180°.
Now we have to find such 3 angles which are less than 90° and add up to 180°.
Let we consider a equilateral triangle.
In a equilateral triangle each angle measures 60°<90°.
and also:
60+60+60=180°.
