A farmer has enough feed to last his 15pigs for 20days. How long would the feed last if he had 10pigs
40/3 days, (13.33 days)
Step-by-step explanation:
Set up the equation, 15/20 = 10/x, and then use cross mutiply to solve it.
10 * 20 = 15x, x = 200/15 = 40/3
Why?
b/c if each pig eats the same amount of food, then the ratio between the number of pigs and days should remain constant.
find the difference. (12m + 1) - (5m - 4)
Answer:
7m + 5
Step-by-step explanation:
1) Simplify.
(12m + 1) - 1 (5m - 4) -> (12m + 1) - 5m + 4
2) Eliminate unnecessary parenthesis.
(12m + 1) - 5m + 4 -> 12m + 1 - 5m + 4.
3) Combine like terms.
12m - 5m = 7m, 4 + 1 =5 -> 7m + 5
The solution is 7m + 5
Write the expression as the
sine or cosine of an angle.
Answer:
sine(pie/5+pie/2)
Step-by-step explanation:
The expression, written as the sine of an angle is sin (7π/10)
Trigonometry Identities
From the question, we are to write the given expression as the sine or cosine of an angle.
The given expression is
sin(π/5)cos(π/2) + sin(π/2)cos(π/5)
Let A = π/5
and
B = π/2
Thus, we get
sinA cosB + sinB cosA
From the given information, we have that
sin(A ± B) = sinA cos B ± cosA sinB
∴ sin(A + B) = sinA cos B + cosA sinB
Now,
sinA cosB + sinB cosA = sinA cosB + cosA sin B
∴ sinA cosB + sinB cosA = sin (A + B)
Put A = π/5
and
B = π/2
sinπ/5 cosπ/2 + sinπ/2 cosπ/5 = sin (π/5 + π/2)
sinπ/5 cosπ/2 + sinπ/2 cosπ/5 = sin (7π/10)
Hence, the expression, written as the sine of an angle is sin (7π/10)

What is the point-slope form of an equation for a line that passes through the point (5, –5) with the slope of 2?
Answer:
y + 5 = 2(x - 5)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 2 and (a, b) = (5, - 5) , thus
y - (- 5) = 2(x - 5) , that is
y + 5 = 2(x - 5)

Answer:

Step-by-step explanation:
Aveterinarian uses the function f(t) =3.7t +21 to estimate a puppy's future weight in pounds as a function of time in months
f(t) = 3.7t + 21
where t is the time in months
f = 3.7t /t + 21 / t
f = 3.7 + 21/t
The puppy's future weight in pounds as a function of time in months can be represented by f = 3.7 + 21/t.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
Given that veterinarian uses the function f(t) =3.7t +21
Thus, f(t) = 3.7t + 21 , where t is the time in months
To estimate a puppy's future weight in pounds as a function of time in months, we have to divide by time t.
f = 3.7t /t + 21 / t
f = 3.7 + 21/t
Hence, the puppy's future weight in pounds as a function of time in months can be represented by f = 3.7 + 21/t.

No estudo da circunferência é muito importante diferenciar diâmetro e raio, muito erros são cometidos pela troca desses conceitos e consequentemente a troca de seus valores. A medida do comprimento de uma circunferência é determinada pela fórmula C = 2 π. R , ou seja comprimento da circunferência é igual ao dobro do valor do π multiplicado pelo valor do raio dessa circunferência. Calcule qual a medida em cm de uma circunferência: a) cujo diâmetro mede 10 cm. b) cujo raio mede 12 cm. c) cujo diâmetro mede 2 cm. d) cujo raio mede 5 cm.
Explicação passo a passo:
A circunferência de um círculo é expressa como mostrado;
C = 2πR
R é o raio
Em termos de diâmetro;
C = πD
D é o diâmetro
a) Se o diâmetro for 10cm
Circunferência C = π (10)
C = 10 (3,14)
C = 31,4cm
b) Se o raio for 12cm
C = 2πR
C = 2π (12)
C = 24π
C = 24 (3,14)
C = 74,36cm
c) Se o diâmetro for 2cm
Circunferência C = π (2)
C = 2 (3,14)
C = 6,28cm
d) Se o raio for 5cm
C = 2πR
C = 2π (5)
C = 10π
C = 10 (3,14)
C = 31,4cm

What was the average number of gallons of fruit juice consumed per person in the country in 2006? Use pencil and paper. Using the per person amount from this problem, about how many gallons would your class consume?
Answer:
Here is what I can do with info given
Step-by-step explanation:
1.56 billion gallons div by 500 million people is 3.12 gallons per person.
So you get 3.12 gallons per person
I don't know how many people are in you're class so

Struggling to do my math work haha please help. Worth 14 points!!!
Answer:
C. y = -1/2 + 2
Step-by-step explanation:
First, we need to find the Slope.
Points: ( -4,4) and (8,-2)
Formula: m = y2 - y1/x2 - x1
m = y2 - y1/x2 - x1
m = -2 - 4/8 - (-4)
m = -6/8 + 4
m = -6/12
m = -1/2
Alright, now that we have the Slope, we can now use the Slope Form to find the Slope Intercept Form.
Point: (8,-2) (You may choose any points, but I would like to choose these for no reason)
Slope: -1/2
Formula: y - y1 = m(x - x1)
y - y1 = m(x - x1)
y - (-2) = -1/2(x - (8))
y + 2 = -1/2x + 4
y = -1/2 + 4 - 2
y = -1/2 + 2
The Slope Intercept Form is: y = -1/2 + 2

Answer: You would have to send 300 text messages
Step-by-step explanation:
1. Turn problem into 20 + 0.10x = 50
2. Subtract 20 from both sides to get 0.10x = 30
3. Divide both sides by 0.10 to get x = 300
