Basically, you have to do 755/12.5 That will give you your average per minute.

To find the average you divide

In this problem you are going to divide the steps by the minutes

755/12 1/2 = 60.4

So his average is 60.4 steps in one minute

In a ratio it would be written like this: 60.4 steps:1 minute

Hope I helped ;)

Simplify the expression. sine of x to the second power minus one divided by cosine of negative x
slega [8]

Answer:

the answer is the letter a) -sin x

Step-by-step explanation:

Simplify the expression.

sine of x to the second power minus one divided by cosine of negative x

(1−sin2(x))/(sin(x)−csc(x))

sin2x+cos2x=11−sin2x=cos2x

cos2(x)/(sin(x)−csc(x))csc(x)=1/sin(x)cos2(x)/(sin(x)− 1/sin(x))= cos2(x)/((sin2(x)− 1)/sin(x))sin2(x)− 1=-cos2(x)cos2(x)/(( -cos2(x))/sin(x))

=-sin(x)

Which answer lists these numbers in order from least to greatest? -24.8,142,1.13,-2.81,24.1
Vadim26 [7]
The answer is a.  -24.8, -2.81, 1.13, -2.81, 24.1

This is because the larger a negative number is, the lower its value is.  So, when putting numbers from least to greatest, you put the largest negative numbers first, and then work your way up to zero.  Then, you start counting upwards with your positive numbers.

Which expression shows 48+36 written as a protuct of two factors
nirvana33 [79]

Answer:

12(4+3)

Step-by-step explanation:

Factor out all of the problems.

Starting with 4(12+4)

This means (4*12)+(4*4)

48+16 is the answer to this

this isn't 48 + 36

12(4+3) is next

12*4 = 48

12*3 = 36

48+36 = 48 + 36

Therefore 12(4+3) is your answer

hope that helps!

hope this is what your looking for
