Ben began peeling a pile of 64 potatoes

klasskru [66]

The number of potatoes peeled by Tom was 36 potatoes after peeling a pile of 64 potatoes

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Let t represent the time after Tom joined.

number of potatoes peeled by Ben = 2(5 minutes) + 2t = 2t + 10

number of potatoes peeled by Tom = 4t

Since they are 64 potatoes, hence:

2t + 10 + 4t = 64

t = 9 minutes

number of potatoes peeled by Tom = 4(9) = 36 potatoes

The number of potatoes peeled by Tom was 36 potatoes after peeling a pile of 64 potatoes

Answer:

In 2008.

Step-by-step explanation:

The function:

$y=4.2\sqrt{0.28x-1}$

Models the annual number of visitors to an amusement park, where <em>y</em> is the number of visitors (in millions) and <em>x</em> is the number of years since 1975.

We want to determine the first year in which the amusement park had 12 million visitors.

So, we will set <em>y</em> equal to 12 and solve for <em>x</em>. This yields:

$12=4.2\sqrt{0.28x-1}$

By dividing both sides by 4.2, we acquire:

$\displaystyle \frac{12}{4.2}=\frac{120}{42}=\frac{20}{7}=\sqrt{0.28x-1}$

And by squaring both sides:

$\displaystyle \frac{400}{49}=0.28x-1$

Adding 1 to both sides produces:

$\displaystyle \frac{400}{49}+1=\frac{449}{49}=0.28x$

And finally, dividing both sides by 0.28 gives us the approximation:

$\displaystyle x=\frac{449}{49}\cdot \frac{1}{.28}=\frac{11225}{343}\approx32.72\approx33$

So, 33 years after 1975, the amusement park will have 12 million annual visitors.

Therefore, the first year in which the amusement park will have 12 million annual visitors is in the year 2008.

There are five consecutive odd integers. The sum of the three smallest is 3 more than the sum of the two largest. Find the integ

lys-0071 [83]

Answer:

The answer is " $\bold{11, \ 13, \ 15, \ 17, \ 19}$ ".

Step-by-step explanation:

In word problem, it is solved by 2k+1, among the most common forms of even an, unlike number.

Let another odd integer become 2k+1.....(a)

(2K+1)+(2k+3)+(2k+5)=(2k+7)+(2k+9)+3(to take the left side 3 extra)

Quality for the k:

$\to 6k+ 9 = 4k +19 \\\\\ \to 6k-4k= 19+9 \\\\ \to 2k = 10 \\\\ \to k = \frac{10}{2}\\\\ \to K = 5$

put the value of k, in the equation (a):

$\to 2k+1 \\ \to 2(5)+ 1 \\ \to 10 + 1\\\to 11\\$

There are also 11, 13, 15, 17, and 19 episodes.

Let's test it! Let's test it. 11+13+15=39

17+ 19 = 36.

So we're right, the first 3 integer numbers are 3 more than the last 2.
