During a 5-year period, 32% of snowstorms in a certain city caused power outage Fifty-one of the snowstorms did not cause power outages. Find the total number of snowstorms in this city over the 5-year period.
Answers
This can be written as 0.68 x = 51 where x is the total number of snowstorms. Divide both sides by 0.68 to solve for x. X = 75 snowstorms. Another way to do this is to use Ratios. See the attached page for the strategy.
Total number of snowstorms = 75 storms
Explanation:
We are given that:
32% of the snowstorms caused power outage
This means that we can get the percentages of the snowstorms that did not cause power outage as follows:
% of storms not causing outage = 100% - 32% = 68%
Now, we are given that the number of snowstorms that did not cause power outage is 51
Assuming that the total number of storms is x, the equation would be as follows:
68% * x = 51
0.68x = 51
x = 51 / 0.68
x = 75 storms

a dinosaur fossil is 92,170,000 years old. How can you express this age in scientific notation with the highest level of precision?
Answers
Answer: Its age is expressed as [tex]9.217\times 10^7[/tex]
Step-by-step explanation:
Since we have given that
Age of dinosaur fossil = 92170000 years old
We need to write in scientific notation with the highest level of precision.
Since we know that Scientific notation means put the decimal just after unit digit and for all remaining digit there is to the power of 10.
So, it becomes,
[tex]92170000=9.217\times 10^7[/tex]
Hence, its age is expressed as [tex]9.217\times 10^7[/tex]

I have to translate these into algebraic expressions. three-fifths x subtracted from 4 times one-eighth w. the other one is 60% of the product of one-twelfth y and two-thirds z.
Answers
0.6(1/12y*2/3z)
The final algebraic expressions are: [tex]\frac{1}{2} w - \frac{3}{5} x[/tex] and [tex]\frac{1}{30} yz[/tex]
Sure, let's break down each part of your question step-by-step to translate them into algebraic expressions.
Three-fifths x subtracted from 4 times one-eighth w
Let's identify the components first:
"Three-fifths x" is written as [tex]\frac{3}{5} x[/tex]."4 times one-eighth w" is written as [tex]4 \times \frac{1}{8} w[/tex] or simply [tex]\frac{4}{8} w[/tex].Now, write the expression for "three-fifths x subtracted from 4 times one-eighth w":
[tex]\frac{4}{8} w - \frac{3}{5} x[/tex]
Simplifying [tex]\frac{4}{8} w[/tex] to [tex]\frac{1}{2} w[/tex], the algebraic expression becomes:
[tex]\frac{1}{2} w - \frac{3}{5} x[/tex]
60% of the product of one-twelfth y and two-thirds z
Let's identify the components first:
"One-twelfth y" is written as [tex]\frac{1}{12} y[/tex]."Two-thirds z" is written as [tex]\frac{2}{3} z[/tex]."Product of one-twelfth y and two-thirds z" is written as [tex]\frac{1}{12} y \times \frac{2}{3} z[/tex].First, calculate the product:
[tex]\frac{1}{12} y \times \frac{2}{3} z = \frac{2}{36} yz = \frac{1}{18} yz[/tex]
Now, we need "60% of that product":
60% can be written as [tex]0.60[/tex], so the expression becomes:
[tex]0.60 \times \frac{1}{18} yz = \frac{3}{90} yz = \frac{1}{30} yz[/tex]
So, the algebraic expression for "60% of the product of one-twelfth y and two-thirds z" is:
[tex]\frac{1}{30} yz[/tex]

y = 5x - 7
Explanation:
The general form of the linear line in slope-intercept form is:
y = mx + c
where:
m is the slope
c is the y-intercept
1- getting the slope:
The slope of the line can be calculated using the following formula:
m = [tex] \frac{y_{2}-y_{1}}{x_{2}-x_{1}} [/tex]
We are given the points:
(3,8) representing (x₁,y₁)
(2,3) representing (x₂,y₂)
Substitute with the givens in the above equation to get the slope as follows:
m = [tex] \frac{3-8}{2-3} [/tex] = 5
Therefore, the equation now became:
y = 5x + c
2- getting the y-intercept:
To get the value of the c, we will use any of the given points, substitute in the equation we got in part 1 and solve for c. I will use point (2,3) as follows:
y = 5x + c
3 = 5(2) + c
3 = 10 + c
c = 3 - 10
c = -7
Based on the above, the equation of the line is:
y = 5x - 7

Answer:
[tex]y= 5x-7[/tex]
Step-by-step explanation:
Using slope-intercept form:
The equation of line is given by:
[tex]y=mx+b[/tex] .....[1]
where,
m is the slope of the line
b is the y-intercept.
As per the statement:
The points (3, 8) and (2, 3) fall on a particular line.
Using slope(m) formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute the given points we have;
[tex]m = \frac{3-8}{2-3}=\frac{-5}{-1}=5[/tex]
⇒m = 5
Put m = 5 in [1] we have;
[tex]y=5x+b[/tex]
Substitute the point (3, 8) we have;
8 = 5(3)+b
8 = 15+b
Subtract 15 from both sides we have;
[tex]-7 = b[/tex]
or
b = -7
Then we have;
[tex]y= 5x-7[/tex]
Therefore, the equation of line in slope intercept form is, [tex]y= 5x-7[/tex]

The quantity demanded x for a product is inversely proportional to the cube of the price p for p > 1. When the price is $10 per unit, the quantity demanded is 64 units. The initial cost is $150 and the cost per unit is $2. What price will yield a maximum profit?
Answers
q(10) = k/10^3 = 64
k = 64,000
Revenue = q(p)*p = 64000/p^2
Cost = 150 +2q = 150 +2*64000/p^3
Profit = Revenue -Cost = 64000/p^2(1 -2/p) -150
Differentiating to find the maximum profit, we have
.. dProfit/dp = -2(64000/p^3) +6(64000/p^4) = 0
.. -1 +3/p = 0
.. p = 3
A price of $3 per unit will yield a maximum profit.
passing through (1,9),slope=2
Answers
Assuming that we want this in slope intercept form, which is y=mx+b (m=slope, b=y-intercept) then we need to find the y-intercept! :)
To find the y-intercept (or b!!) you simply need to plug everything into slope intercept form using our given points.
y = mx + b
Plug everything in.
9 = 2(1) + b
Simplify.
9 = 2 + b
Subtract 2 from both sides.
9 - 2 = b
b = 7
Therefore, our y-intercept is 7! :)
Now that we have both the y-intercept and the slope, we can finally plug this into a new equation, using slope intercept form.
y = mx + b
y = 2x + 7
~Hope I helped!~
Here the slope is 2.
Then, y = 2x + b
The line is passing through (1;9).
We just have to substitute that in the equation.
9 = 2*1+ b
b = 9 - 2
b = 7
That's the intercept.
Eventually, the equation is : y = 2x + 7
Hope this helps !

A hockey game between two teams is 'relatively close' if the number of goals scored by the two teams never differ by more than two. In how many ways can the first 12 goals of a game be scored if the game is 'relatively close'?
Answers
This question falls under the combinatorial mathematics branch. Due to the complex nature of the problem which involves permutations and combinations, it's necessary to use a systematic approach or a computer algorithm to find the total number of scoring sequences that keeps the game 'relatively close'. Hence, the actual numerical answer would require a stronger background in combinatorics.
Explanation:This question belongs to the subject of combinatorial mathematics, particularly involving permutations and combinations. In this scenario, 'relatively close' is defined as the number of goals scored by the two teams never differing by more than two. The total number of goals scored in the game is twelve.
Let's denote the two teams as Team A and Team B. The game can start in three ways: either Team A scores twice, Team B scores twice, or each team scores once. After that, at any point, the next goal can either maintain the score within the 'relatively close' range of two goals or equalize the score.
Determining the total number of scoring sequences under these conditions requires generating a tree diagram and counting all the possible paths, subject to the condition that the absolute difference between the number of goals for the two teams does not exceed two at any stage. Due to the combinatorial complexity, this task could be difficult without using a systematic approach or computer algorithm.
Therefore, to actually answer this question, one would require a stronger background in combinatorics, and most likely the assistance of programming or mathematics software to execute a brute force count or implement a more advanced mathematical solution.
