Count the number of digits after the first digit. this gives you the exponent on the 10. The first number in scientific form has the decimal point after the first digit.
For mercury there are 7 digits after the 5:-
So the Mercury answer is
5.7909175 * 10^7
Follow this procedure for the other planets
The answer for Venus is
1.08208930 * 10^8
14-8=6. So far we have 3 km, then 6 divided by 2 which is 3 additional kilometers. 3+3 is 6 so the final answer is 6km
Answer:The area of each triangle is one-half the area of the rectangle. So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.
Step-by-step explanation:
Mick would pay $4.06 in sales tax for an item that costs $58.00.
This can be found by working backwards in the problem. By dividing that sales tax paid (2.94) by the dollars before tax (42), you get a percentage that should equal the percentage of the total paid for tax.
2.94 ÷ 42 = 0.07
This means that the sales tax is 7% of the total prior to tax. So we'd then multiply our dollars (58) with the sales tax in decimal form (0.07)
58.00 × 0.07 = 4.06
