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:
she has 90 feet of ribbon in total and she can cut 270 pieces
Step-by-step explanation:
there's 108 inches in 9 feet
108/4=27
now you have 10 rolls so multiply
27x10=270 ribbons
you have 10 rolls of 9 feet to make ribbons
10x9=90 feet
1) "Subtract -7a+1 from 7+a" means -7a+1 is getting taken away from 7+a, so this can be mathematically expressed as:
Starting expression: (7+a)-(-7a+1)
Distributive property with negatives: 7+a+7a-1
Combine like terms: 6+8a
So the answer for the first one is 6+8a
2) "Subtract -4v-2 from -2-5v" means -4v-2 is getting taken away from -2-5v, so this can be mathematically expressed as:
Starting expression: (-2-5v)-(-4v-2)
Distributive property with negatives: -2-5v+4v+2
Combine like terms: -v
So the answer for the second one is -v
Hope these explanations are clear.
Answer:
7.5%
Step-by-step explanation:
280 - 259 = 21
21 / 280 = 0.075 = 7.5%
Answer:
The answer is y-3
Step-by-step explanation:
Simplify terms
4y-12+9-3y
Combine like terms.
4y-3y=y
-12+9=-3
So the answer is y-3
