F = 1/5 gh^2
solve for h
Answer:
First of all, let's multiply both sides by 5, clearing the denominators:
Then, as long as g is not zero, we can divide by g, and let's read right to left:
At this point, assuming F and g are either both positive or both negative, we can take the square root of both sides:
If h represent a quantity that is positive by it's nature (ie, the length of a segment) you can consider only the positive root, ie ignoring the plus or minus sign.
Edwin and Franklin share money in the ratio 3:7 Franklin received $20 more than Edwin. Find the amount shared and what each of them received.
Step-by-step explanation:
We have,
Edwin and Franklin share money in the ratio 3:7.Franklin received $20 more than Edwin.We've to find the amount shared and what each of them received.
★ Amount Shared = Amount received by Edwin + Amount received by Franklin ★
As, Edwin and Franklin share money in the ratio 3:7. So, let's say that,
Amount received by Edwin = $ 3xAmount received by Franklin = $ 7xAlso, Franklin received $20 more than Edwin. So,
→ Amount received by Franklin = 20 + Amount received by Edwin
→ 7x = 20 + 3x
Solving the equation further.
→ 7x - 3x = 20
→ 4x = 20
→ x = 20/4
→ x = 5
Hence,
→ Amount received by Edwin = $ 3x
→ Amount received by Edwin = $ 3(5)
→ Amount received by Edwin = $ 15 [Ans]
And,
→ Amount received by Franklin = $ 7x
→ Amount received by Franklin = $ 7(5)
→ Amount received by Franklin = $ 35 [Ans]
Lastly,
→ Total amount shared = 3x + 7x
→ Total amount shared = $35 + $15
→ Total amount shared = $50 [Ans]
Hence, solved!I need help asap please!
can someone please help me out with this as ive tried to put everything to solve it but im still wrong.
kind regards

Cuanto es 1/3 + 5/8 + 1/2
Answer:
35/24
Step-by-step explanation:
1/3 + 5/8 + 1/2
8/24 + 15/24 + 12/24
Hola!
Primero, debes asegurarte de que todas las funciones compartan el mismo denominador.
4(1/2)= 4/8
1/3 + 5/8 + 4/8
1/3 + 9/8
Ahora necesitamos encontrar un denominador común de 3 y 8.
El mínimo común múltiplo de 3 y 8 es 24.
8(1/3)= 8/24
3(9/8)= 27/24
8/24 + 27/24= 35/24
Entonces tu respuesta es 35/24!!

1) Statements Reasons
ABCD is a trapezoid Given
AD ║ BC bases of trapezoid are parallel
∠AED = ∠CEB vertically opposite angles are equal
∠EBC = ∠ADE alternate interior angles are equal and BD is transversal
∠ECB = ∠EAD alternate interior angles are equal and AC is transversal
ΔAED ~ ΔCEB ∠ECB = ∠EAD & ∠AED = ∠BEC & ∠EBC = ∠ADE
all angles are same and their shape is same, so similar
2) hope you can write 2nd one as above two column proof
T is the mid point of QR
U is the mid point of QS
V is the mid point of RS
Definition: The segment of line joining the middle points of two sides of a triangle is called middle segment.
Inference: A middle segment of a triangle is parallel to the third side and its lengths is half the third side's.
so here TU ║ RV and TU = RV
UV ║ TR and UV = TR
so TUVR becomes a parallelogram
∠TUV = ∠TRV --------> condition 1
same goes with parallelogram TQUV
∠TQU = ∠UVT ----------> condition 2
same goes with parallelogram TUSV
∠UTV = ∠USV ------------> condition 3
from the above 3 conditions we can say
ΔQRS ~ ΔVUT
3) see the below figure for graph
in both triangles ∠B is common
AC and TS are parallel lines
BC and BA are transversals
∠C ∠S are equal --> corresponding angles
∠A ∠T are equal ---> corresponding angles
so ΔABC & ΔTBS are similar

you could give away 70 coffee mugs without charging anything.
If you charge $10.00, nobody will buy the coffee mugs. You also figured out that your sales will be decreasing
following straight line. Your job is to find the maximum possible revenue from selling the coffee mugs.
Answer the following questions:
1. Graph the linear relationship between the price of coffee mugs p, and the number of coffee mugs sold S.
Hint: To give away 70 coffee mugs means when the price p=0, S(0) = 70. Plot that point on the graph. Find one
more point using the other given condition. Keep in mind S(p) is a linear function. Be careful what will be
represented on the x-axis, and what will be represented on the y-axis.
2. Find the equation of the linear function S(p) that describes the quantity sold as a function of the price p.
3. The revenue is determined by R = Sp. Express the revenue as a function of the price p.
Help: You may look at the examples from the power point for section 2.6
4. Graph the revenue function. Make sure to label the x - and the y - axis with the appropriate units.
5. At which price per coffee mug do you not make any money?
6. Find the price per coffee mug that makes the most revenue.
7. How many coffee mugs must be sold to maximize the revenue?
8. What is the maximum revenue?
9. What price per coffee mug you should charge to collect at least $70 in revenue?
Your project will be graded based on the following:
1. Turned in a hard copy, and an electronic version as a PDF file on Blackboard on time (due date Dec 7
or before ) (5pts. deduction per day)
2. Completeness (no missing part, show all of your work, calculations, formulas used etc.
3. Precision ( correct answers )
4. Complete graph
the graph has a title
the axes are labeled ( make sure you have included the units of measurement)
-
At $ 10 per mug you will not get any money; the maximum possible revenue is $ 175, which will be obtained by selling the mugs for $ 5; and to get at least $ 70 in revenue the mugs must be sold for $ 2.
Since you could give away 70 coffee mugs without charging anything, and if you charge $ 10.00, nobody will buy the coffee mugs, and you also figured out that your sales will be decreasing following straight line, and your job is to find the maximum possible revenue from selling the coffee mugs, to determine at which price per coffee mug do you not make any money; the price per coffee mug that makes the most revenue; how many coffee mugs must be sold to maximize the revenue; what is the maximum revenue; and what price per coffee mug you should charge to collect at least $ 70 in revenue; the following calculations must be performed:
70 = 0 0 = 10 35 = 5 63 x 1 = 63 56 x 2 = 112 49 x 3 = 147 42 x 4 = 168 35 x 5 = 175 28 x 6 = 168
Therefore, at $ 10 per mug you will not get any money; the maximum possible revenue is $ 175, which will be obtained by selling the mugs for $ 5; and to get at least $ 70 in revenue the mugs must be sold for $ 2.

What is the equation of a line that is parallel to – 2x + 3y = -6 and passes through the point (-2, 0)?
Answer:
y = 2/3x + 4/3
Step-by-step explanation:
you need to know the slope of the line -2x + 3y = -6 because parallel lines have the same slopes
let's put the equation in y=mx+b format (slope-intercept format)
-2x + 3y = -6
add 2x to each side to get:
3y = 2x - 6
divide each side by 3 to get:
y = 2/3x - 2
the equation now shows us the slope is 2/3 and the y-intercept is (0,-2)
now we use y=mx+b again and use the point (-2,0) and the m=2/3 to get the y-intercept ('b' value) of the equation that is parallel:
0 = 2/3(-2) + b
0 = -4/3 + b
b = 4/3
equation would be:
y = 2/3x + 4/3

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day!!
We can solve this problem in two steps, Comprehension and Solving
I'll start off with comprehension.
Comprehension
We know that ratios are basically fractions as they both show comparison, so we can make x:y into [tex]\frac{x}{y}[/tex].
We also have another equation, making this problem a system of equations.
Now that we know what to do, we can begin solving!
Solving
We can solve this by first getting our two equations.
[tex]\frac{x}{y}=\frac{2}{3}[/tex]
We can simplify the 2nd equation so that we know what one variable is.
[tex]x+y=10\\x=10-y[/tex]
We can now input our second equation into the first equation.
[tex]\frac{10-y}{y}=\frac{2}{3}\\3(10-y)=2y\\30-3y=2y\\30=5y\\y=6[/tex]
If y is six, then we can use the second equation to solve for x.
[tex]x+6=10\\x=4[/tex]
We know that x is 4 and y is 6.
We can now check our answers.
1st Equation
[tex]\frac{4}{6}=\frac{2}{3}?\\[/tex]
[tex]\frac{2}{3}=\frac{2}{3}[/tex]
2nd Equation
[tex]4+6=10?\\10=10[/tex]
We've proven our answers to be right, therefore, x is 4 and y is 6.

Answer:
(1, −2)
Step-by-step explanation:
−3x + 1 = 2x − 4
−5x + 1 = − 4........subtract 2x from both sides
-5x = -5.................subtract 4 from both sides
x = 1.......................divide both sides by - 5

The lines represented by the equations y + 3/2x = -6 and 3y – 2x = -24 are
parallel
neither parallel nor perpendicular
perpendicular
the same line
Answer:
Neither Parallel nor Perpendicular
Step-by-step explanation:
Convert 3y - 2x = -24 to slope - intercept form
3y - 2x = -24
3y = -24 + 2x
3y = 2x - 24
y = 2/3x - 8
They are neither parallel or perpendicular
Parallel lines have the same slope, but these are different
Perpendicular lines have the opposite inverse (negative reciprocal) slope, but these are just reciprocals
