How do I express the letters in bracket as the subject of the formula ?
especially the 1/2 power is new and unfamiliar to me.
Answer:
[tex]n = 144m^2 - 1[/tex]
Step-by-step explanation:
__________________________________________________________
FACTS TO KNOW BEFORE SOLVING :-
Let x be a number. ⇒ [tex]x^{\frac{1}{2}}[/tex] can also be written as [tex]\sqrt{x}[/tex].To make any variable the subject of any formula , we need to isolate it.__________________________________________________________
According to the question ,
[tex]3m = \frac{(n + 1)^{\frac{1}{2} }}{4}[/tex]
Lets multiply both the sides by 4.
[tex]=> \frac{(n + 1)^{\frac{1}{2} }}{4} \times 4 = 3m \times 4[/tex]
[tex]=> (n + 1)^{\frac{1}{2} } = 12m[/tex]
It can be also written as :-
[tex]=> \sqrt{(n + 1)} = 12m[/tex]
Lets square both the sides.
[tex]=> [\sqrt{(n + 1)} ]^{2} = (12m)^{2}[/tex]
[tex]=> n + 1 =144m^2[/tex]
[tex]=> n = 144m^2 - 1[/tex]

Answer:
8x - 4y = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 and c = - [tex]\frac{3}{4}[/tex] , then
y = 2x - [tex]\frac{3}{4}[/tex] ← in slope- intercept form
Multiply through by 4 to clear the fraction
4y = 8x - 3 ( subtract 4y from both sides )
0 = 8x - 4y - 3 ( add 3 to both sides )
3 = 8x - 4y , or
8x - 4y = 3 ← in standard form
The cost c in dollars of manufacturing x bicycles at a production plant is given by th function shown below C(x)=5x^2-1000x+63,500. How many bicycles must be manufactured to minimize the cost
Answer:
100 bicycle
Step-by-step explanation:
Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.
x is the number of bikes
To minimize the cost, dC/dx = 0
dC/dx = 10x - 1000
Since dC/dx = 0
0 = 10x - 1000
-10x = -1000
x = 1000/10
x = 100
Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle

if I cupcake have 240 calories for 3 servings how many calories would it have for 5 servings
Answer:
400 calories
Step-by-step explanation:
One cupcake has 80 calories. 80 x 5 = 400
Answer:
400 Calories
Step-by-step explanation:
If there are 240 calories in 3 servings, In one serving there must be 80 because
240/3 = 80
And since there are 80 calories in one serving, in 5 servings there will be 5 times the amount of calories there is in one serving so
5 * 80 = 400

For volunteers picked up letter from the park Dominic you collect and 15 for your pieces a litter than Sarah Sarah collect the 12 more pieces in piper piper collected 1/4 as many pieces of litter as Vaughn Vaughn has collected nine more pieces of wood or than everyone else combine the X represent the number of pieces of litter Vaughn Collection
So many confusing details. So, I rephrase the question as:
Four volunteers picked up litters from the park.
Dominic collect 15 pieces less than Sarah. Sarah collects 12 more pieces than Piper. Piper collected 1/4 as many pieces of letter as Vaughn. Vaughn has collected nine more pieces of letter than everyone else combined. Let x represent the number of pieces of litter in Vaughn's Collection. Find x
Answer:
[tex]x = 72[/tex]
Step-by-step explanation:
Let:
[tex]D = Dominic;\ \ S = Sarah;\ \ P = Piper;\ \ V = Vaughn[/tex]
From the [rephrased] question, we have:
[tex]D = S - 15[/tex]
[tex]S = 12 + P[/tex]
[tex]P = \frac{1}{4}V[/tex]
[tex]V = 9 + D + S + P[/tex]
Substitute [tex]S = 12 + P[/tex] in [tex]D = S - 15[/tex]
[tex]D = 12 + P - 15[/tex]
[tex]D = P+12 - 15[/tex]
[tex]D = P-3[/tex]
Make V the subject in [tex]P = \frac{1}{4}V[/tex]
[tex]V = 4P[/tex]
Substitute: [tex]V = 4P[/tex], [tex]D = P-3[/tex] and [tex]S = 12 + P[/tex] in [tex]V = 9 + D + S + P[/tex]
[tex]4P= 9 + P - 3 + 12 + P +P[/tex]
Collect like terms
[tex]4P - P -P-P= 9 - 3 + 12[/tex]
[tex]P= 18[/tex]
Substitute [tex]P= 18[/tex] in [tex]S = 12 + P[/tex]
[tex]S = 12 +18[/tex]
[tex]S = 30[/tex]
Substitute [tex]S = 30[/tex] in [tex]D = S - 15[/tex]
[tex]D = 30 - 15[/tex]
[tex]D =15[/tex]
Substitute [tex]D =15[/tex], [tex]S = 30[/tex] and [tex]P= 18[/tex] in [tex]V = 9 + D + S + P[/tex]
[tex]V = 9 + 15 + 30 + 18[/tex]
[tex]V = 72[/tex]
x represents the number collected by Vaughan.
So:
[tex]x = 72[/tex]

marty has 1 1/3 jugs of apple juice. he uses 3/4 of the juice to make freeze pops. what fraction amount of a jus doe marty have?
Answer:
He has 1/3 of a jug left.
Step-by-step explanation:
He starts with 1 1/3 jugs.
He uses 3/4 of 1 1/3 jugs.
A full amount is 1 or 4/4. If he uses 3/4, he has 1/4 left since
1 - 3/4 = 4/4 - 3/4 = 1/4
That means he has 1/4 of 1 1/3 jugs left.
We need to multiply 1/4 by 1 1/3.
1/4 * 1 1/3 =
= 1/4 * 4/3
= 4/12
= 1/3
Answer: He has 1/3 of a jug left.
Delaney is saving money in an account that offers 9% simple interest. She deposits 2000 from her grandmother into the account and makes no additional deposits or withdraws. How many years will it take to grow to 4,700
Answer:
15years
Step-by-step explanation:
Given data
Rate= 9%
Principal= $2000
Final amount= $4700
The simple interest formula is given as
A= P(1+rt)
Substitute
4700=2000(1+0.09*t)
4700= 2000+ 180t
4700-2000= 180t
2700=180t
t= 2700/180
t= 15 years
Hence the time is 15years
Triangle ABC is reflected over the x-axis. У C(5, - 1) | A(0, - 2) -3 -4 B(2, - 4) 5 -6 What are the vertices of AA'B'C '?
Answer:
The vertices of the triangle A'B'C' are [tex]A'(x,y) =(0,2)[/tex], [tex]B'(x,y) = (-2,4)[/tex] and [tex]C'(x,y) = (-5,1)[/tex], respectively.
Step-by-step explanation:
Vectorially speaking, the reflection of a point over the x-axis is defined by the following expression:
[tex]P'(x,y) = P(x,y) -2\cdot P(x,y)[/tex]
[tex]P'(x,y) = -P(x,y)[/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.
[tex]P'(x,y)[/tex] - Reflected point.
If we know that [tex]A(x,y) = (0,-2)[/tex], [tex]B(x,y) = (2,-4)[/tex] and [tex]C(x,y) = (5,-1)[/tex], then the vertices of the triangle A'B'C':
[tex]A'(x,y) =(0,2)[/tex], [tex]B'(x,y) = (-2,4)[/tex], [tex]C'(x,y) = (-5,1)[/tex]
The vertices of the triangle A'B'C' are [tex]A'(x,y) =(0,2)[/tex], [tex]B'(x,y) = (-2,4)[/tex] and [tex]C'(x,y) = (-5,1)[/tex], respectively.
