Sara's savings account balance changed by -$34 one week and by -$67 the next week .Which amount represents the greater change?

Answers

Answer:

Change in one week is more than the change in the next week

Step-by-step explanation:

Change in Sara's savings account balance in one week = $- \$ 34$

Change in Sara's savings account balance in next week = $- \$ 67$

Tens digit in 34 = 3

Tens digit in 67 = 6

If we compare the tens digit of 34 and 67, we get $6> 3$

So, $67> 34$

On multiplying both sides by -1 , we get $-67< -34$ .

{ We know that negative sign changes sign of inequality }

So, we get change in one week is more than the change in the next week .

The greater change is represented by the absolute magnitude

|-34| = 34
|-67| = 67

67 > 34

-67 represents the greater change

Answer:

16,800 votes.

Step-by-step explanation:

In the singing competition 42,000 votes were counted.

The winner received 3/5 of the votes.

The part of the votes that the winner did not receive was 1 - 3/5 = 2/5

So the winner did not receive 2/5 of 42,000 votes which is equivalent to:

$(2(42,000))/(5)$ = 16,800 votes.

Mr.Planter wants to have the largest piece of cake he can. Should he slice his cake into thirds or fourths? Which would result in a larger piece? Explain

Answers

Mr.Planter should split the cane in to thirds because a whokr cake equals 100% and 1/3 of acane equals 33.3% where as if you were to split it into 1/4 it would only equal 25% for each piece of cake.

researchers counted 8,912 monarch butterflies on one branch of a tree at a site in Mexico. They estimated that the total number of butterflies at the site was 1000 times as large. About how many butterflies were at the sitein all. Explain your thinking and include a statement of the solution.

Answers

The total number of the butterflies are $\fbox{\bf8912000}$ .

Further explanation:

Given:

The number of monarch butterflies on one branch of a tree at a site in Mexico are 8912 and the total number of butterflies at the site are 1000 times as large.

Calculation:

Consider, the number of the butterflies on one branch of a tree at a site in Mexico as $x$ and total number of butterflies as $y$ .

Since, the total numbers of butterflies at the site are 1000 times the number of the butterflies on one branch of a tree at a site in Mexico.

The total number of butterflies $y$ can be written as follows:

$y=1000x$ …… (1)

Substitute 8912 for $x$ in equation (1).

$\begin{aligned}y&=1000\left( {8912}\right)\n&=8912000\n\end{aligned}$

Thus, the total numbers of the butterflies are $\fbox{\bf8912000}$ .

Lines, equation, monarch butterfly, x=2y, function, substitution, Mexico, site, direct substitution, elimination, graph, middle term factorization, fraction.

Approximately 8,912,000 monarch butterflies were at the site. By using powers of 10, I can conclude that doing 8,912 x 1000 would mean adding three zeros to 8,912, making 8,912,000. So, 8,912,000 would be the logical estimate.
