Answer:
8.
Step-by-step explanation:
-9 x x = -72.x = 8.In all of the steps to solve this specific question, x is a variable to represent the other factor, that we are trying to find out the answer to, and our equation that we need to set up for this problem, is -9 times x equals -72, because -9 multiplied by the other factor that we are trying to solve for, which is x in this case, should equal -72. So then, to completely finish simplifying this equation, we need to divide -9 from both sides, so we can get our variable x, that we are trying to get the answer for, by itself. Then finally, you get x equal to 8, as our final, simplified answer. These are all of the steps to completely get the correct answer to your question.

A spherical boulder is 14 ft in diameter and weighs almost 6 tons. Find the volume. Use 3.14 for pi.
To find volume, we will use the following equation: V=4/3piR^3
The correct answer should be 1436.76
The volume of the spherical boulder will be 1,436.027 cubic feet.
What is the volume of the sphere?Let r be the radius of the sphere. Then the volume of the sphere will be given as,
V = 4/3 πr³ cubic units
A spherical boulder is 14 ft in diameter. Then the radius is calculated as,
r = d / 2
r = 14 / 2
r = 7 feet
Then the volume of the spherical boulder is calculated as,
V = 4/3 πr³
V = 4/3 x 3.14 x 7³
V = 1,436.027 cubic feet
The volume of the spherical boulder will be 1,436.027 cubic feet.

Which triangle has a bigger area:
1. A triangle with sides measuring 300, 400, and 500.
2. A triangle with sides measuring 300, 400, and 700.
The 2nd triangle has a bigger area, because since it has 2 sides that are equal to the first and its 3rd side is larger than the 1st triangle, it would have larger area, because it would have to have a larger area to have a larger side.
Answer:
Which triangle has a bigger area:
1. A triangle with sides measuring 300, 400, and 500.
2. A triangle with sides measuring 300, 400, and 700.
Step-by-step explanation:
The second triangle has the largest area, because although the two triangles have two sides with the same size, the third is larger in the second triangle, 700 of the second, versus 500 of the first, and hence the area is also greater than in the first.

Answer:
measure of angle R is 75.897° or 75.90°.
Step-by-step explanation:
To solve use the formula Sin A/ a= Sin B/ b. our angle A is 52°, opposite it is side a so 26. Let angle R be our B so opposite it is b which measure 32.
sin 52°/26 = Sin B/32, cross multiply
32 (sin 52°) = 26 Sin B, multiply both side by 1/26
32 (sin 52°)/26 = Sin B
32 (0.78880107536...)/26 = Sin B
0.969593891... = Sin B
Sin^-1 (0.969593891..) = B
B = 75.89703075 or Angle R is 75.90°

A triangle has an area of 221.16 square inches. The height of the triangle is 29.1 inches. What is the length of the triangle?
Answer:
15.2
Step-by-step explanation:
please help!!!!!!!!!!!!
Answer:
see answers in bold below
Step-by-step explanation:
a. The area of each red triangle is given by the formula for the area of a triangle:
A = 1/2·bh
The base is 14 ft - 10 ft = 4 ft. The height is shown as 4 ft, so the area of each triangle is ...
A = (1/2)(4 ft)(4 ft) = 8 ft²
Then the red area is that of the two triangles:
red area = 2·(8 ft²) = 16 ft²
The white rectangle area is the product of its length and width:
white area = (8 ft)(4 ft) = 32 ft²
The area of the whole central parallelogram is the product of its length and width:
parallelogram area = (14 ft)(8 ft) = 112 ft²
But the yellow area is the difference between this value and the white area:
yellow area = 112 ft² -32 ft² = 80 ft²
__
b. The area to be primed is the sum of the areas to be painted different colors:
primed area = red area + white area + yellow area
= 16 ft² + 32 ft² + 80 ft²
primed area = 128 ft²
_____
In the attached figure, each grid square is 2 ft.
What is the difference between a sequence and a series? What is the difference between a geometric and an arithmetic sequence?
Answer:
Sequence: ordered list of numbers
Series: sum of the terms of a sequence
Arithmetic sequence: the difference between the terms is constant
Geometric Sequence: the ratio between the terms is constant
Step-by-step explanation:
The difference between a series and a sequence is that a sequence is a list of numbers that follow a pattern or rule.
For example
1, 3, 5, 7, 9...
[tex]a_n = 1 +2(n-1)[/tex]
On the other hand, a series is the sum of the terms of a sequence.
1 + 3 + 5 + 7 + 9 + ...+ n
[tex]\sum_{n=1}1 +2 (n-1)[/tex]
----------------------------------------------------------------------------------
The difference between an arithmetic sequence and a geometric sequence is that:
for the arithmetic sequences the subtraction of:
[tex]a_n - a_{n-1} = d[/tex]
Where d is a constant called difference..
In the Arithmetic sequence the difference between the terms is constant
For the geometric sequences, it is satisfied that the quotient between two consecutive terms is:
[tex]\frac{a_{n-1}}{a_n} = r[/tex]
Where r is a constant value called common ratio
In geometric Sequence the ratio between the terms is constant
Final answer:
A sequence is an ordered list of numbers, while a series is the sum of the terms of a sequence. An arithmetic sequence has a constant difference between terms, while a geometric sequence has a constant ratio.
Explanation:
Difference Between Sequence and Series
A sequence is an ordered list of numbers following a specific pattern, while a series is the sum of the terms of a sequence. For example, in the sequence 2, 4, 6, 8, ..., each term is 2 more than the previous term. However, when these terms are added together, for instance, 2 + 4 + 6 + 8, we get a series.
Difference Between Geometric and Arithmetic Sequences
An arithmetic sequence is characterized by a constant difference between consecutive terms. For example, the sequence 3, 7, 11, 15, ... has a common difference of 4. On the other hand, a geometric sequence has a common ratio between consecutive terms, such as the sequence 2, 6, 18, 54, ... where each term is 3 times the previous term.

The line plot shows the weights of packages of meat available at a grocery store. The 3 lightest packages cost $4.40 per pound. The remaining packages cost $4.80 per pound. If a customer buys all available packages, how much does she spend? Choose the numbers to complete the statements.
Answer:
$42.40
Step-by-step explanation:
The horizontal axis is in fractions.
The three lightest are two [tex]\frac{5}{8}[/tex] pounds & one [tex]\frac{6}{8}[/tex] pounds. Each cost $4.40 per pound.
So cost = 4.40(5/8+5/8+6/8) = $8.8
Remaining costs 4.80 per pound. We add up the remaining and multiply by 4.80 to get their cost.
cost = [tex]4.80(1+1\frac{1}{8}+1\frac{1}{8}+1\frac{1}{8}+1\frac{2}{8}+1\frac{3}{8})=33.6[/tex]
Hence, total cost = 8.8 + 33.6 = $42.40
Answer:
40.40 is actually the answer for the last one and the first one is 8.80
then the second one is 33.60 so yw

Up and Running Auto Shop keeps track of their regular customers' data to see if there is a relationship between the life of a car's engine (y) and the number of times the oil is changed (x). When the data is shown on a scatter plot, the equation for the line of best fit is y = 0.4125x + 0.1576. What is the relationship between 0.4125 and the life of the car's engine?
Answer:
Strong and Positive Relation
Step-by-step explanation:
Here, when we plot the graph of y = 0.4125x + 0.1576
Then we see that the graph has a positive correlation as we increase the value of x, the value of y is also increasing. So, Life of Car's Engine and Number of Times the Oil is Changed has a Positive relation.
And if our scatter plot is horizontal, vertical or we unable to draw the line of best fit then it has no or little correlation but here we see that line is not lie in either case. So, the relationship is strong but not very strong.
Answer :
A) 0.4125 shows how much the longevity of the engine increases with each oil change.
B) 0.4125 shows the expected longevity with no all changes.
C) 0.4125 shows the expected longevity for all engines, with or without oil changes.
D) 0.4125 is the expected decrease in longevity for each year without an oil change.

Which equation is NOT a linear? function
Answer:
Step-by-step explanation:
A linear function involves two variables which are in their first power form, such as x and y.
A nonlinear function may include two variables, one or more of which are of the 2nd or higher power.
Unfortunately, you did not share the possible answer choices, so I cannot be more specific. I'd suggest you repost this question, with answer choices, if you still want guidance here.
y = x^2 - 2 is NOT a linear function, because of that power (2). Note how all the other choices show x to the 1st power.
A linear function is represented by an equation in the form y = a + bx and generates a straight line when plotted on a graph. Any equation that does not fit this form, such as quadratic, exponential, trigonometric, or inverse functions, which generate curves when plotted, are not linear functions.
Explanation:The question asks which equation is not a linear function. A linear function is one that can be represented by an equation in the form y = a + bx, where 'a' and 'b' are constants and 'x' is the independent variable. This form of function generates a straight line when plotted on a graph, with 'b' representing the slope of the line and 'a' representing the y-intercept, where the line crosses the y-axis.
An equation that does not fit this form is not a linear function. For instance, a quadratic function, represented by a second-order polynomial equation such as y = ax^2 + bx + c, is not linear. These types of equations generate curves when plotted on a graph, not straight lines.
Futhermore, any other function types such as exponential, trigonometric, or inverse, which generate curves that are not straight lines when plotted, are also not linear functions.
