If 2 quarts of paint are needed for 75 ft of fence, how many quarts are needed for 900 ft of fence
Answer:
24 quarts
Step-by-step explanation:
1 qrt = 75/2 = 37.5
900 / 37.5 = 24
solve 3^y = 12 and
find y
Answer:
3^y = 12Take the logarithm of both sides of the equation to remove the variable from the exponent. Exact Form:y = [tex]\frac{ln 12}{ln 3}\\\\\\[/tex] = (ln 12)/(ln 3)y = 2.261help now plz just help plzzz

Tyree and four friends go to the movies. Each person buys a movie ticket for $7, a snack for $5, and a drink for $2. Write an expression for the total cost of the trip to the movies. Then find the total cost.
Answer:
Tyree and all of his friends get 1 ticket for $7. Next they all get 1 snack for $5. Then they all get a drink for $2. So:
1=7
1=5
1=2
Then you take each person (which there are five of then) and you times all five people by 7, 5, 2.
5 x 7=35
5 x 5=25
5 x 2=10
After that you add it all together:
35 plus 25=60
60 plus 10=70
Step-by-step explanation:
your welcome
Answer:
Im not sure if it ment, Tyree and four friends go to the movies. Each person buys a movie ticket for $7, a snack for $5 (meaning only one snack), and a drink for $2. (Meaning only one drink) or if it ment Tyree and four friends go to the movies. Each person buys a movie ticket for $7, a snack for $5 (meaning everyone got a snack), and a drink for $2(meaning everyone got a drink). So i did the math for both of them, if they only got 5 tickets, one snack, and one drink, it would be 42 (the math problem is 35 + 2 + 5). if they got 5 tickets, 5 snacks, and 5 drinks, it would be 70(the math problem is 35 + 25 + 10). Hope this helps!
Which of the following is 3x²/12x simplified?
3x/12
x/4
x/3
x²/4x
Answer:
I think it is the last one
Step-by-step explanation:
y is inversely proportional to x . When y = 30 , x = 3 Work out x when y = 6
Step-by-step explanation:
yx = k, where k is a real constant.
When y = 30, x = 3.
=> k = (30)(3) = 90.
Hence when y = 6, x = k/y = (90)/(6) = 15.
What does a decimal between two fractions mean
Answer:
Multiplication
Step-by-step explanation:
I think what you're talking about is not a decimal, but a multiplication point:

This dot can donate multiplication when in the middle of two numbers and/or fractions.
But if you're talking about some other point, then I don't know, sorry. :(

Paralell to the line y=3x + 5 and has a y-intercept of -1
Step-by-step explanation:
Everything the parallel lines has the same slope
[tex]y = mx + b[/tex]
m = slope
b = y intercept
then the equation of the line is:

Find the average rate of change of f(x) = 2x ^ 2 - 7x from x = 2 to x = 5 Simplify your answer as much as possible .
The average rate of change for a function between two points is the slope of the secant line that contains the two points.
f(2)=2(2)^+10=18
f(5)=2(5)^+10=60
Therefore the two points are (2,18) and (5,60)
Use the slope formula:
m=y1-y2/x1-x2
where (x1,y1) and (x2,y2) are the coordinates of the given points.

A carpenter is building a rectangular shed with a fixed perimeter of 54 ft. What are the dimensions of the largest shed that can be built? What is its area?
Answer:
the Largest shed dimension is 13.5 ft by 13.5 ft
Largest Area is 182.25 ft²
Step-by-step explanation:
Given that;
Perimeter = 54 ft
P = 2( L + B ) = 54ft
L + B = 54/2
L + B = 27 ft
B = 27 - L ------------Let this be equation 1
Area A = L × B
from equ 1, B = 27 - L
Area A = L × ( 27 - L)
A = 27L - L²
for Maxima or Minima
dA/dL = 0
27 - 2L = 0
27 = 2L
L = 13.5 ft
Now, d²A/dL² = -2 < 0
That is, area is maximum at L = 13.5 using second derivative test
B = 27 - L
we substitute vale of L
B = 27 - 13.5 = 13.5 ft
Therefore the Largest shed dimension = 13.5 ft by 13.5 ft
Largest Area = 13.5 × 13.5 = 182.25 ft²
