If 3 = 1/2gt^2, make t the subject of the formula<br>​
Montano1993 [528]

Answer:

t = √1.5/g

Step-by-step explanation:

1/2gt^2 = 3

Divide both sides by 1/2

gt^2 = 1.5

Divide both sides by g

t^2 = 1.5/g

Square root both sides

t = √1.5/g

you earn $420 per week. You pay social security taxes of 7.65% federal taxes of 22%, and state taxes of 5.95%. What is your take
Marysya12 [62]
First you need to solve for how much you lose for each individual tax, so 420x.0765 will give you how much money you lose to social security tax, then do the same for the other types and add them together, the value will give you the amount you have lost, so taking the total (420) minus the amount lost you will have the amount that you can "take home" So 420-((420x.0765)+(420x.22)+(420x.0595)) = amount still in your pocket

A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid i
Temka [501]

Answer:

9.48

Step-by-step explanation:

Complete question

<em>A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid 90.1. What is the height of the​ pyramid?</em>

To get the height of the pyramid, we will use pythagoras theorem.

slant height l is the hypotenuse

length of the base is the adjacent

height of the pyramid is the opposite

According to the theorem;

l² = h² + b²

90.1² = h² + 89.6²

8,118.01 = <em>h²+</em>8,028.16

h²= 8,118.01 - 8,028.16

h² = 89.85

h =√89.85

h = 9.48

Hence the height of the pyramid will be 9.48

<em>Note that the value of the slant height was assumed to solve the problem</em>.

What value of x will make this equation true? (2x)3 + 2x = 222?
Alex_Xolod [135]
6x+2x=222, which means 8x=222. Thus, x=222/8, which is 27.75.

The sum of three consecutive odd numbers is one hundred and eleven. what is the smallest of the three numbers?
Firdavs [7]
35,37,39
111 divided by 3 is 37...so that is the middle number.  Two below it is 35 and 2 above it is 39 and all three would add up to 111.  So 35 is the lowest.
