What is 14 ten thousands+12 thousands

Answers

14 ten thousands is (14*10,000) which gives you 140,000
so you would do 140,000 + 12,000 which gives you 152,000

Karen will divide her garden into equal parts she will plant corn and 8/12 of the garden what is the fewest number of parts she can divide her garden into

Answers

Answer – 3 parts
The garden is divided into 12 parts.
Karen will plant corn on 8/12 of the garden (or 2/3 of the garden, if both the numerator and denominator are divided by 4).
 Therefore, the fewest number of parts she can divide her garden into is 3. She will plant corn on 2/3 of the garden and the other 1/3 of the garden will not be planted with corn.

A sequence is defined recursively by f(1) = 16 and f(n) = 3f(n-1) +2. Find f(4)

Answers

If you would like to find f(4), you can calculate this using the following steps:

f(1) = 16
f(n) = 3 * f(n-1) + 2
f(2) = 3 * f(2-1) + 2 = 3 * f(1) + 2 = 3 * 16 + 2 = 48 + 2 = 50
f(3) = 3 * f(3-1) + 2 = 3 * f(2) + 2 = 3 * 50 + 2 = 152
f(4) = 3 * f(4-1) + 2 = 3 * f(3) + 2 = 3 * 152 + 2 = 458

The correct result would be f(4) = 458.

Final answer:

You can solve the quadratic equation using the quadratic formula. For the system of three equations, use basic algebra according to the given condition. The equation involving sum of products can be solved by performing individual multiplications and then calculating the sum.

Explanation:

To help you understand and solve these mathematical equations, let's break them down. For the

quadratic equation

4.90t² + 20t +c = 0, you can use the quadratic formula to find the values of t. It's important to note here that the quadratic formula is [-b ± sqrt(b² - 4ac)] / (2a).

Also, given the system of three equations and three unknowns (Qd, Qs, and P), you can solve these using basic algebra. With Qd = Qs you can set the demand and supply equations equal to each other: 16 - 2P = 2 + 5P. You can then rearrange and solve for P.

Lastly, you have an equation where calculation of the sum of the products is involved: 1(.35) + 2(.20) + 3(.15) + 4(.15) + 5(.10) + 6(.05) = 2.6 years. This means that each number is multiplied by the corresponding percentage and then all results are added up.

If Ben bikes 3 miles and then bikes 1,000 yards back toward his starting point, how many yards is Ben from his starting point?

Answers

First lets convert the 3 miles to yards. 3 miles is equal to about 5280 yards . So now we have to subtract 5280 yards by 1,000 which is equal to 4,280.
So the final answer is 4,280.
To answer this we will first convert d 3 miles to yards. den we will subtract the 1,000 yards and d answer will be d amount of yards Ben is from his starting point. lets do it:-

1 mile = 1760 yards

Now lets multiple:-

1760 × 3 = 5280
3 miles = 5280 yards

lets subtract now:-

5280 - 1000 = 4280

So, Ben is 4,280 yards far from his starting point.
