S=3Lw+3wh+4hL solve for h

Mathematics
1 answer:
maw [93]3 years ago
4 0
S = 3Lw + 3wh + 4hL   Subtract 3Lw from both sides
S - 3Lw = 3wh + 4hL   Factor out h
S - 3Lw = h (3w + 4L)   Divide both sides by (3w + 4L)
\frac{S - 3Lw}{3w + 4L} = h   Switch the sides to make it easier to read
h =  <span>\frac{S - 3Lw}{3w + 4L}</span>

How do you find the area of a triangular prism
sasho [114]

Answer:The formula A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height. The formula A=lw is used to find the area of the three rectangular side faces, where A = area, l = length, and w = width.


Plugging in the measurements that are given in the net, calculate the area of each face. Remember to use the correct area formula for the triangles

jamie has taken three math tests. her scores were 85, 90, and 89. to get an average of 90 what must be the sum of all her tests
Zinaida [17]

Answer:

96 marks

Step-by-step explanation:

We know that the mean of a given amount of values is the sum of the values divided by the number of values

Let the marks in the fourth test = x marks

Mean of the values = 90

(85 + 90 + 89 + x) / 4 = 90

264 + x = 360

x = 96

Therefore, Jamie needs 96 marks in her 4th test to get a mean score of 90

Quadrilateral RJFT is similar to quadrilateral SYPA . JF=60 mm , AP=40 mm , and YP=25 mm . What is TF ?
Hoochie [10]
The two quadrilaterals are similar. Which means the ratios of respective sides of two quadrilaterals will be the same. 

So, for the given quadrilaterals, ratio of sides JF and TF of quadrilateral RJFT will be equal to the ratio of sides YP and AP of quadrilateral SYPA. Mathematically, we can write:

JF:TF = YP:AP \\  \\ &#10; \frac{JF}{TF} = \frac{YP}{AP}  \\  \\ &#10; \frac{60}{TF} = \frac{25}{40}  \\  \\ &#10;60* \frac{40}{25}=TF \\  \\ &#10;TF=96mm

So the measure of TF will be 96mm
