Svetlana's hair is 4 centimeters long. her hair grows 1.51 centimeters per month. svetlana wants her hair to grow so that it is at least 7 centimeters long. write an inequality to determine the number of months, mm, it will take svetlana's hair to grow so it is at least 7 centimeters long.

2 months

Step-by-step explanation:

first subtract Svetlana present hair length from the desired hair length in order to find out how much growth is required.

7-4=3

so Svetlana needs to grow 3 more cm of hair

Next divide the 3 cm needed to reach the desired length by the rate of growth to find the number of months.

3cm/1.5cm/m =2months

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.

step-by-step explanation:

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
