$55 per gallon. 1 gallon covers 100sqft. What is the price per sqft?
The price per square foot is 0.55$
Step-by-step explanation:
We can solve this problem by applying the rule of three.
In fact, we know that:
- The price per 1 gallon is $55
- The area covered by 1 gallon is [tex]100 ft^2[/tex]
So this means that the price per [tex]100 ft^2[/tex] (1 gallon) is $55.
Here we want to find the price per square foot, so we can write:
[tex]\frac{x}{1}=\frac{55}{100}[/tex]
And solving for x, the price per square foot, we find:
[tex]x=\frac{55}{100}=0.55[/tex]
So, the price per square foot is 0.55$.

If a point is chosen inside the circle, what is the probability that it will also be inside the square?
The probability that a point chosen inside a circle will also be inside a square is π/4.
Explanation:The probability that a point chosen inside a circle will also be inside a square can be determined by comparing the areas of the circle and the square. Let's assume that the circle has a radius of r and the square has sides of length 2r. The area of the circle is πr2 and the area of the square is (2r)2 = 4r2. Therefore, the probability of the point being inside the square is given by the ratio of the area of the circle to the area of the square: P = (πr2) / (4r2) = π/4.

7(x-10)-2(x+5)=4x-7+6x-3
Final answer:
The algebraic equation 7(x-10)-2(x+5)=4x-7+6x-3 simplifies through distribution, combining like terms, and isolating x, resulting in the solution x = -14.
Explanation:
The student's question involves solving the algebraic equation 7(x-10)-2(x+5)=4x-7+6x-3. To solve this equation, we will simplify and solve for x, demonstrating the process step-by-step.
Step 1: Distribute and Simplify
First, distribute the numbers outside the parentheses:
7(x-10) becomes 7x - 70 and
-2(x+5) becomes -2x - 10.
The equation now looks like 7x - 70 - 2x - 10 = 4x - 7 + 6x - 3.
Step 2: Combine Like Terms
On the left side of the equation, combine 7x and -2x to get 5x. Also, combine -70 and -10 to get -80.
On the right side, combine 4x and 6x to get 10x, and -7 with -3 to get -10.
Step 3: Further Simplification and Solving for x
Now, the equation is 5x - 80 = 10x - 10. Subtract 5x from both sides to get -80 = 5x - 10. Adding 80 to both sides gives us 0 = 5x + 70. Subtract 70 to get 5x = -70. Finally, divide by 5 to find that x = -14.
In conclusion, through the steps of distribution, combining like terms, and isolating x, we find the solution to the original algebra problem to be x = -14.

what value of x makes the equation 3(x-6)-8x=-2+5(2x+1) true ?
Answer:
x = (-7)/5
Step-by-step explanation:
Solve for x:
3 (x - 6) - 8 x = 5 (2 x + 1) - 2
3 (x - 6) = 3 x - 18:
3 x - 18 - 8 x = 5 (2 x + 1) - 2
Grouping like terms, 3 x - 8 x - 18 = (3 x - 8 x) - 18:
(3 x - 8 x) - 18 = 5 (2 x + 1) - 2
3 x - 8 x = -5 x:
-5 x - 18 = 5 (2 x + 1) - 2
5 (2 x + 1) = 10 x + 5:
-5 x - 18 = 10 x + 5 - 2
Add like terms. 5 - 2 = 3:
-5 x - 18 = 10 x + 3
Subtract 10 x from both sides:
(-5 x - 10 x) - 18 = (10 x - 10 x) + 3
-5 x - 10 x = -15 x:
-15 x - 18 = (10 x - 10 x) + 3
10 x - 10 x = 0:
-15 x - 18 = 3
Add 18 to both sides:
(18 - 18) - 15 x = 18 + 3
18 - 18 = 0:
-15 x = 3 + 18
3 + 18 = 21:
-15 x = 21
Divide both sides of -15 x = 21 by -15:
(-15 x)/(-15) = 21/(-15)
(-15)/(-15) = 1:
x = 21/(-15)
The gcd of 21 and -15 is 3, so 21/(-15) = (3×7)/(3 (-5)) = 3/3×7/(-5) = 7/(-5):
x = 7/(-5)
Multiply numerator and denominator of 7/(-5) by -1:
Answer: x = (-7)/5

How many solution does the inequality x>12 have explain
infinity numbers above 12
The inequality x > 12 has infinitely many solutions as it represents all numbers greater than 12 without any upper limit.
Explanation:The inequality x > 12 actually has infinitely many solutions, since any number greater than 12 satisfies the inequality condition.
In mathematics, inequalities that do not contain restrictions other than the comparative operator (in this case, '>') have a set of solutions that can be represented on a number line extending infinitely in one direction.
For example, if x > 12, then numbers such as 13, 14.5, 100, and 1234 are all solutions.
This can be visualized on a graph where x > 12 would be shown as an open interval starting from 12 and extending to the right toward infinity.

How do you find a volume of a cone?
Answer:
V = (1/3)πr²h
Step-by-step explanation:
The volume of a cone is 1/3 the volume of a cylinder with the same radius and height.
Cylinder Volume = πr²h
Cone Volume = (1/3)πr²h
where r is the radius (of the base), and h is the height perpendicular to the circular base.
_____
Comment on area and volume in general
You will note the presence of the factor πr² in these formulas. This is the area of the circular base of the object. That is, the volume is the product of the area of the base and the height. In general terms, ...
V = Bh . . . . . for an object with congruent parallel "bases"
V = (1/3)Bh . . . . . for a pointed object with base area B.
This is the case for any cylinder or prism, even if the parallel bases are not aligned with each other. (That is, it works for oblique prisms, too.)
Note that the cone, a pointed version of a cylinder, has 1/3 the volume. This is true also of any pointed objects in which the horizontal dimensions are proportional to the vertical dimensions*. (That is, this formula (1/3Bh), works for any right- or oblique pyramid-like object.)
__
* in this discussion, we have assumed the base is in a horizontal plane, and the height is measured vertically from that plane. Of course, any orientation is possible.

Is it random, systematic, stratified, or cluster?
Answer:
Cluster
Step-by-step explanation:
Random: Each element in the population has an equal probability of selection, and each combination of elements has an equal probability of selection. For instance picking a picking name from a hat.
Stratified: Divide population into groups called strata that differ in important ways. For instance, for a population of a state, male and female strata. for people working in a city, resident and non-resident strata
Systematic: Each element has an equal probability of selection, but combinations of elements have different probabilities
Cluster: this is a form of random sampling. Population is divided into groups, usually geographic or organizational
In a year group of 60 pupils, 3/4 like Coke, 1/5 like Sprite and 3/10 like Tango. How many children like each drink? PLZ HELP ME ASAP 15 points to correct answer
Final answer:
To find out how many children like each drink in a year group of 60 pupils, calculate each fraction of the total. 45 pupils like Coke, 12 pupils like Sprite, and 18 pupils like Tango.
Explanation:
In a year group of 60 pupils, to find out how many children like each drink, you need to calculate the fractions of the total number of pupils.
To find out how many like Coke, multiply 3/4 by the total number of pupils: 3/4 × 60 pupils = 45 pupils.For Sprite, multiply 1/5 by the total number of pupils: 1/5 × 60 pupils = 12 pupils.For Tango, multiply 3/10 by the total number of pupils: 3/10 × 60 pupils = 18 pupils.Therefore, 45 pupils like Coke, 12 pupils like Sprite, and 18 pupils like Tango.
Final answer:
45 children like Coke, 12 children like Sprite, and 18 children like Tango.
Explanation:
To find out how many children like each drink, we can use the given fractions and the total number of children in the year group.
Let's calculate the number of children who like Coke:
Total children in the year group = 60
Fraction who like Coke = 3/4
Number of children who like Coke = (3/4) x 60 = 45
Similarly, we can calculate the number of children who like Sprite and Tango:
Fraction who like Sprite = 1/5
Number of children who like Sprite = (1/5) x 60 = 12
Fraction who like Tango = 3/10
Number of children who like Tango = (3/10) x 60 = 18
Therefore, 45 children like Coke, 12 children like Sprite, and 18 children like Tango.
