Someone Please Help!!! A barrel of tomato sauce has spilled on a tile floor. The sauce flow can be expressed with the function r(t) = 2t, where t represents time in minutes and r represents how far the sauce is spreading.

The spilled sauce is creating a circular pattern on the tile. The area of the pattern can be expressed as A(r) = πr2.

Part A: Find the area of the circle of spilled sauce as a function of time, or A[r(t)]. Show your work. (6 points)

Part B: How large is the area of spilled sauce after 5 minutes? You may use 3.14 to approximate π in this problem. (4 points)

Final answer:

The product of 70 and 10 to the power of 4, which can be solved using multiplication in scientific notation, is 7.0 × 105, or 700,000 in standard notation.

Explanation:

The question asks for the product of 70 times 10 to the power of 4. To solve this, we use the rule of multiplication in scientific notation wherein you multiply the numbers and then add the exponents. Hence, the equation is (7.0 × 101) × (1.0 × 104). In this equation, we multiply 7.0 and 1.0 to get 7.0, then add the exponents 1 and 4 to get 5. The answer is therefore 7.0 × 105, or 700,000 when written in standard notation.

Step-by-step explanation:

just try this

take any two measurements and add them together if they are larger than the 3rd measurement it will work and all you have to do is do that to each measurement

10+5 is greater than 9

9+5 is greater than 10

9+10 is greater than 5

Answer:

5

Step-by-step explanation:

Assuming the n+9 is in the denominator, start by cross multiplying.

multiply the n+9 by 2 and 4 by 7 to form the eqution 2n+18 = 28.

subtract the 18 from both sides to form the equation 2n = 10.

divide both sides by 2 to answer n = 5.

Another method is to think how to create equivalent fractions. to have 4/n+9 equal 2/7, the 2/7 is equivalent to 4/14. that means that n+9 is equivalent to 14, because the numerator are equal to each other. if n+9 = 14, then n = 5.
