Answer:

There were 62 deaths

Step-by-step explanation:

In this question, we are asked to calculate the number of robberies in 2012.

From the question we can identify that the number of robberies were up 50% to 93. What this means is that the number is simply 150% of the old number.

Now, let’s represent the number of deaths in 2012 by x

Mathematically;

150% of x = 93

150/100 * x = 93

150x = 93 * 100

150x = 9300

x = 9300/150

x= 62

This means there were 62 deaths in the year 2012

Answer:

There were 62 robberies in Springfield in 2012.

Step-by-step explanation:

Let's marked (named) robberies in 2012 with x, which is worth 100%

93 robberies in 2013 worth 100% + 50% = 150%

Now we will make proportion

x : 93 = 100 : 150

When we multiply external and internal members we get

x/93 = 100/150

Cross multiply

150 x = 93 × 100

150x = 9300

x = 9300/150

x = 62 robberies in 2012

195/279 = 130/x

195x = 279 times 130
195x =36,270
x = 36,270/195
x = 186

A patient weighing 130 pounds needs 186 milligrams of medicine.

Answer:

90

Step-by-step explanation:

4/15 which is our fraction distance/time

our other fraction is 24/x (x is our variable to find our time)

Now we are doing the buultterfly method

set it up

now multiply 4*x= 4x

15*24=360

now divide 4x ÷ 4 to get our variable alone

do the same to the other side

4 ÷ 360= 90

so x= 90 which is our missing number

Find the unknown side length
Westkost [7]
For any right triangle, we can use the Pythagorean Theorem. The Pythagorean Theorem states that for any right triangle, the legs when squared and added together will be equal to the hypotenuse squared.

In mathematical notation: a^2 + b^2 = c^2

Where the variables a and b are the legs and the variable c is the hypotenuse.

Because we know the two side lengths of the triangle, we can solve for the unknown side.

We know the length of one of the legs and the hypotenuse.

Plug in the values.

10^2 + b^2 = 24^2 \\ \\ 
100 + b^2 = 576 \\ \\ 
b^2 = 476 \\ \\ 


b = \sqrt{476}

So, the square root of 476 is the unknown length.
