Answer:
0 = 4x +20 +80=2×(2x +14)0=2x+14=)2x =-14=)x =-7Answer:
x = 7
Step-by-step explanation:
0 = 4(x+5) + 8
expand:
0 = 4x + 4*5 + 8
0 = 4x + 20 + 8
0 = 4x + 28
simplify
4x = 28
simplify
x = 28 / 4
x = 7
the volume of a bucket of water is 864 cubic inches. how many buckets are needed to fill a 7 cubic foot tank?
Answer:
We have the relation:
1ft = 12 inches.
Then, if we cube both sides, we have:
(1ft)^3 = (12 in)^3
1ft^3 = 288 in^3.
Now we know that:
The bucket is 864 in^3
The tank is 7 ft^3.
knowing that 1 ft^3 = 288in^3
Then 7 ft^3 is seven times that:
7ft^3 = 7*(1ft^3) = 7*(288in^3) = 2016 in^3
Now the number of buckets needed to completely fill the tank is:
N = (2016 in^3)/(864in^3) = 2.33
So you need 2.33 buckets, or we can round it up to 3 buckets, where the third bucket will have some water inside it when the tank is completely filled.

Answer:
7.1 cm
Step-by-step explanation:
The diagonal of a cube connects two opposite corners.
You can use the diagonal of a cube in a right triangle in which it is the hypotenuse. The legs of the triangle are a diagonal of a face and an edge.
Let the length of the edge be s.
a^2 + b^2 = c^2
[tex] s^2 + 10^2 = (\sqrt{150})^2 [/tex]
[tex] s^2 + 100 = 150 [/tex]
[tex] s^2 = 50 [/tex]
[tex] s = \sqrt{50} [/tex]
[tex] s = 5\sqrt{2} [/tex]
s = 7.1

stadium already has 250 people in it at noon.If 35 people per minute enter the stadium,how many are in the stadium at 1:30 p.m. when a concert is supposed to begin?
Answer:
3,400 people
Step-by-step explanation:
First, find how many minutes are between noon and 1:30 pm
This is an hour and 30 minutes, so it will be 90 minutes
Then, multiply 90 by 35, since 35 people enter per minute
90(35)
= 3150
Then, add the 250 people that were already in it
3150 + 250
= 3400
So, there will be 3,400 people in the stadium
Answer:
3400
Step-by-step explanation:
250+35m=noon
How does the absolute value take away negative signs
Step-by-step explanation:
the absolute value is the numbers UNIT DISTANCE from the origin (0,0). since you can't have negative distance, the result is always positive. Can be solved by counting distance on a graph Not by the actual numbers on the line (-1,-2,-3, etc) but by counting the "boxes" from a point to the origin. hope this makes sense!
Answer:
the absolute value of negative number makes it a positive number
Find f(2) for the following functions: f(x) = x - 14
Answer:
f(2) = - 12Step-by-step explanation:
f(x) = x - 14
To find f(2) substitute the value of x that's 2 into f(x). That is for every x in f(x) replace it with 2
We have
f(2) = 2 - 14
We have the final answer as
f(2) = - 12Hope this helps you
Here, we are given with a polynomial f(x)
[tex]f(x) = x - 14[/tex]
And we are asked to find f(2).....?
We can see that, 2 is in place of x. So for finding its value, we need to substitute 2 in place of x.
Substituting 2 in place of x:
[tex]f(x) = x - 14[/tex]
[tex]f(2) = 2 - 14[/tex]
Solving further,
[tex]f(2) = \boxed{- 12}[/tex]
And, we're done with the value of f(2)

Step-by-step explanation:
The amount of milk remaining is equivalent to 4 gallons.
What is a function? What is equation modelling? What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionEquation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that Jansen family has 2 1/2 gallons of milk. Each of the 3 family members drinks 1 1/2 cups of milk a day.
1 gallon = 16 cups
2[tex]\frac{1}{2}[/tex] gallons = 2[tex]\frac{1}{2}[/tex] x 16 = 5/2 x 16 = 5 x 8 = 40 cups
Now -
Total milk consumed in 1 day = 3 x 3/2 cups = 9/2 cups = 4.5 cups.
In 8 days, the amount of milk consumed will be = 4.5 x 8 = 36 gallons.
Remaining amount = 40 - 36 = 4 gallons.
Therefore, the amount of milk remaining is equivalent to 4 gallons.

John's teacher bought three 64 ounce bottles of soda for a class party. At the end of the party, 1/6 of the soda remained. How many ounces of soda remained?
Answer:
32 ouncesStep-by-step explanation:
If John's teacher bought three 64 ounce bottles of soda for a class party, the total weight of the soda bought will be 3*64 = 192 ounces of soda.
If 1/6 of the soda remained after the party, the amount of ounces that remained is expressed as;
amount of ounces that remained = 1/6 * 192
amount of ounces that remained = 32 ounce
Hence amount of ounces that remained is 32 ounces

Step-by-step explanation:
Mr Chan bought 20 computers and 25 printers for $30 000. Each computer costs $1250. At a promotion sale, Mr Chan sold each computer at $1700 with a free printer. The selling price of each printer when sold separately was $250.
Find the cost price of each printer.
Answer:
$200.
Step-by-step explanation:
Each computer costed $1,250.
Mr. Chan bought 20 computers.
20 × $1,250 = $25,000
$25,000 out of the $30,000 was spent on computers. That leaves $5,000. Which means $5,000 was spent on the printers.
$5,000 ÷ 25 = $200
(25 = amount of printers.)
So each printer was $200.

What is the answer to -2r-4r=0
Answer:
r = 0
Step-by-step explanation:
First, combine like terms:
(-2r - 4r) = 0
(-6r) = 0
Isolate the variable, r. Divide - 6 from both sides:
(-6r)/-6 = (0)/-6
r = 0/-6 = 0
r = 0 is your answer.
