1. 9.355 × can be used to express the age of the dinosaur fossil.
Step-by-step explanation:
Step 1; To determine which value is the closest to 93,550,000 we must calculate how much the 4 options equal. If there are decimals in the number, they are moved from the decimal part of the number to the integer part with every power of 10 i.e. 2.4 × 10 = 24, 2.44 × 10² = 244.
Step 2; Now we determine how much the 4 options equal.
1. 9.355 × = 93,550,000.
2. 9 × = 90,000,000.
3. 9.36 × = 93,600,000.
4. 9.3 × = 93,000,000.
Out of the four options, option 1 equals the value of 93,550,000. So option 1 can be used to express the age with the highest precision.
Answer:
Surface area = 6l^2
Volume = l^3
If total surface area increased by 2, then the length increased by
Volume then is increased by (l)^3 = 2
l^3
1 :2
Which is not an option in the question so this question clearly has a problem.
First of all It's supposed to be "then" not "than," so I'm not sure who teaches math without even knowing this basic grammar.
Second of all, if the answer is 8:1 the question should be "If <u>each sides</u> of a cube is doubled" not "the lateral surface area." Come to think of it what even is lateral surface area of a cube if all sides of the cube is supposed to be same.
Or, if the answer is 2:1 then, it should be If height lateral surface area of a cube is doubled <u>by doubling the height and without changing the length and width</u>" But, then the the shape would no longer be a cube.
Who even wrote this garbage question what.
