Answer: There were 212 robberies in 2012.

Step-by-step explanation:

Since we have given that

Number of robberies in Springfield in 2013 = 265

Rate of growth in 2013 = 25%

We need to find the number of robberies there were in 2012.

Let the number of robberies in 2012 be x

so, According to question,

\frac{100+25}{100}\times x=265\\\\\frac{125}{100}\times x=265\\\\1.25\times x=265\\\\x=\frac{265}{1.25}\\\\x=212

Hence, there were 212 robberies in 2012.

Keith_Richards [23]

The rate of change of the area of the triangle when t=1 is also equal to 3.

<h3>Rate of change</h3>

Given the function of height of a triangle expressed as:

  • h(t) = 3t + 1

The rate of change is expressed as

  • dh/dt = 3

The rate of change of the area of the triangle when t=1 is also equal to 3.

On average, Makenzie runs 4 miles in 50 minutes. How fast should she plan to run a 10-mile race if
pishuonlain [190]

Answer: A

Step-by-step explanation:

The easiest way to solve this problem would to first figure out how long it takes for Mak to run 1 mile. To do that, you would need to divide 50 by 4 which would give you 12.5. So, it takes Mak 12 and a half minutes to run 1 mile. From there, you would need to multiply 12.5 by 10 to get 125. Finally, you wold need to simplify 125 minutes to hours giving you 2 hours and 5 minutes.

How can a conjugate be created from a complex number?
ratelena [41]
Remember that (a-b)(a+b)=a²-b²
and (imaginary number)²=real

so if we have a+bi, then a-bi is the conguate because (a+bi)(a-bi)=a²+b²


if the complex number is a+bi the conjucate is a-bi

Find the missing number in this proportion <br> Help
Triss [41]

Answer:

9

Step-by-step explanation:

To solve, we can first cross multiply

28/63=4/x

28*x=63*4

28x=252

Since we are trying to find x(the missing number), we need to get x by itself. x is being multiplied by 28. To undo this, divide both sides by 28. This will cancel out 28 and leave x by itself.

28x/28=252/28

x=9

So, the missing number is 9

28/63=4/9
