pentagon [3]3 years ago

Answer:

(H)^2=(B)^2 +(P)^2

(13cm)^2=(12cm)^2 +(P)^2

169cm^2=144cm^2 +(P)^2

169cm^2-144cm^2 =(P)^2

25cm^2 = (P)^2

Now taking square root on both sides

5cm = P

Oksana_A [137]

Answer:

x = 12

Step-by-step explanation:

In a right triangle (a triangle that has a ninety degree angle in it) the the square of the side opposite the right angle is always equal to the sum of the squares of the other two sides. Therefore, we can use the information we are given to figure out the missing side:

15^2=225\\9^2=81\\225-81=144\\\sqrt[2]{144}=12

What are the two things do you need to write an equation?
dlinn [17]

Answer:

Slope and y intercept.

Step-by-step explanation:

This is necassary to write the equation of a line in y=mx+b

m is where the slope goes, and b is the y intercept.

Alternatively, you could also write the equation for a line with a point on the line and the slope.

You would then write it in point slope formula:

y-y1=m(x-x1)

This can later be converted into slope intercept form.

Marcus reads for 30 minutes each night. He wants to determine the total number of minutes he will read over the course of a mont
Ivenika [448]

Answer:

The time is independent of the months we multiply these minutes as grouping with subject impression or importance. This way within the frequency you can see 263340 represents what score you are looking for importance ie) 20/20 for your book choice. This is 8 days which fits better for a monthly review 8,8,8 and 6. Which would easily be readable in the minute totals.

240= 8 nights  180 minutes = 6 nights. Having a frequency helps determine patterns for  book interest and study.

Step-by-step explanation:

         Subjects (imp)                  Minutes (M P/D)             F(Frequency)

score 1-3                                     30                                   60

         4-6                                     60                                  300

         7-9                                     60                                  420

        10-12                                   90                                  990

Total  26                  +                240   ...266 x990  = 263340
