What is the smallest counting number divisible by 2, 4, 5, 6, and 12
10t+[tex]\geq[/tex]130+3.5t
Answer:
The answer is [tex]t\geq 20[/tex].
Step-by-step explanation:
To solve the inequality, start by solving for the variable [tex]t[/tex].
To solve for the variable [tex]t[/tex], subtract [tex]3.5t[/tex] from both sides. The inequality will look like [tex]6.5t\geq 130[/tex].
Then, divide both sides by 6.5 in order to get the variable [tex]t[/tex] by itself. The inequality answer will look like [tex]t\geq 20[/tex].

the students in charge of the class booth at a carnival would like to earn $3 for every item they sell. they spent $55 for the materials to make the items. solve the inequality 3x-55_>65 which represents how many items they need to sell to make profit of at least $65
Answer:
x ≥ 40
Step-by-step explanation:
3x - 55 ≥ 65
combine like terms
3x ≥ 65 + 55
3x ≥120
divide both sides of the equation by 3
x ≥ 40

Cary calculated the surface area of a box in the shape of a rectangular prism. She wrote the equation 148 = 2 (6w + 6h + hw) to represent the width and height of the box. She solved for w and got w = StartFraction 74 minus 6 h Over h + 6 EndFraction Which of the following is an equivalent equation?
Answer:
the answer is w = 148-12h/12+2h
The equivalent equation is -
[tex]$w=\frac{74-6h}{h+6}[/tex]
We have the equation written by Carly → 148 = 2 (6w + 6h + hw) that represent the width and height of the box in the shape of a rectangular prism.
We have to solve for w.
What do you mean by Equivalent expression ?Any expression written in a form different from the original form, but gives same result for any input are called equivalent expressions.
Solve for x : [tex]$log(\frac{x}{\omega}) = 2\pi[/tex]We have -
[tex]$log(\frac{x}{\omega}) = 2\pi[/tex]
log(x) - log(ω) = 2π
log(x) = 2π + log(ω)
x = [tex]e^{(2\pi + log(\omega))} = e^{2\pi } \times e^{log(\omega)}[/tex]
According to the question, we have -
148 = 2 (6w + 6h + hw)
(6w + 6h + hw) = 74
hw + 6w = 74 - 6h
w(h + 6) = 74 - 6h
[tex]$w=\frac{74-6h}{h+6}[/tex]
Hence, the equivalent equation is -
[tex]$w=\frac{74-6h}{h+6}[/tex]

A population of small bottles and their contents has the following weights (in grams): 4, 2, 5, 4, 5, 2, and 6. What is the variance of bottle weight?
A. 6.92.
B. 4.80.
C. 1.96.
D. 2.33.
Answer:
D. 2.33.
Step-by-step explanation:
Given;
the weight distribution of the bottles = 4, 2, 5, 4, 5, 2, and 6
sum of the weights = 28
the mean (x) = 28/7
x = 4
the sum of square of the mean deviation is calculated as:
= (4 - 4)² + (2 - 4)² + (5 - 4)² + (4 - 4)² + (5 - 4)² + (2 - 4)² + (6 - 4)²
= 0 + 4 + 1 + 0 + 1 + 4 + 4

Solve for X.
Multiple choice!
Thank you!
Answer:
9
Step-by-step explanation:
the 2 angles create a right angle ( indicated by the little square.)
right angles have a measure of 90 degrees
hence, 90 = 72 + 2x
( note that we just created an equation that we can use to solve for x )
we now solve for x using the equation we created.
90 = 72 + 2x
step 1 subtract 72 from each side
90 - 72 = 18
72 - 72 cancels out
we now have 18 = 2x
step 2 divide each side by 2
18 / 2 = 9
2x / 2 = x
we're left with x = 9
Find the equation of the line that

and contains the point (8, 1).
y =
x+
Enter
Answer:
Step-by-step explanation:
L : y = -4x + 3
with a slope of -4.
Any line perpendicular to L will have a slope m such that
m ( -4) = -1, or m = 1/4
Any line perpendicular to L passing through point (a,b) will therefore have the form
P : (y-b) = (x-a)/4
When (a,b) = (8,1) as given, then substitute in P to get
P : (y-1) = (x-8)/4
y=x/4 -2 + 1
y = x/4 -1

Step-by-step explanation:
Since there are plenty of lines that can pass through a single point, he only way to solve this question is by substituting values of [tex]3[/tex] into each equation and seeing if both equations return a value of [tex]-2[/tex].
Starting with the first answer choice:

Since none of the equations here return a value of [tex]-2[/tex], the correct answer must not include [tex]-\frac{1}{3}x+3[/tex] or [tex]x-1[/tex].

A hardware store wants to enclose a 800 square foot rectangular area adjacent to its store to display gardening equipment. One side will be formed by the wall of the store. The side opposite the store will be constructed with steel fencing costing $6 per foot and the other two sides will be constructed with wood fencing costing $3 per foot. What are the dimensions that will minimize cost
Answer:
x = 20√2 ft and y = 40/√2 ft
Step-by-step explanation:
Let; x = length of steel fencing
y = length of a wood fence that is perpendicular to the store
Thus, since area is 800 ft², then;
xy = 800
Length of fence; L = x + 2y
From earlier, xy = 800
y = 800/x
Thus;
L = x + 2(800/x)
L = x + 1600/x
Now, steel fencing costing $6 per foot and the other two sides will be constructed with wood fencing costing $3 per foot. Thus, total cost is;
C(x) = 6x + 3(2y)
But y = 800/x. Thus;
C(x) = 6x + 3(1600/x))
C(x) = 6x + 4800/x
C'(x) = 6 - 4800/x²
At C'(x) = 0, the cost is minimized.
Thus=
6 - 4800/x² = 0
6x² = 4800
x² = 4800/6
x² = 800
x = √800
x = 20√2
When 0 < x < 20√2, C'(x) < 0, so we say that C(x) is decreasing
When x > 20√2, C'(x) > 0, so we say that C(x) is increasing
Thus, the cost is minimized when x = 20√2
Thus, putting 20√2 for x in y = 800/x, we have;
y = 800/(20√2)
y = 40/√2
Thus, dimensions that will minimize cost are;
x = 20√2 ft and y = 40/√2 ft
