To find the number of field trips Cornell's class took last year, we set up the equation 3x + 1 = 7, where x represents the number of trips last year. Solving this, we find that Cornell's class took 2 field trips last year.
The question involves a basic mathematical equation to determine the number of field trips taken by Cornell's class last year. Since this year Cornell's class took 7 trips, and this number is one more than three times the amount of the previous year, we can set up the equation as x being the number of trips taken last year:
3x + 1 = 7
To find x, subtract 1 from both sides of the equation:
3x = 7 - 1
3x = 6
Now divide both sides by 3 to solve for x:
x = 6 / 3
x = 2
So, Cornell's class took 2 field trips last year.
if an arc has a measure of 97° and the circle has radius = 10, what is the arc length
Final answer:
The arc length of a circle with a radius of 10 units and a central angle of 97° is calculated using the formula for arc length, yielding an arc length of approximately 16.975 units.
Explanation:
The question asks us to find the arc length of a circle with a certain radius when a central angle is given. To find the arc length, we use the formula:
Arc length (s) = (θ/360) × 2πr
Where θ is the central angle in degrees, r is the radius of the circle, and π is approximately 3.14159. Since we know the central angle is 97° and the radius is 10, we can plug these values into the formula:
s = (97/360) × 2×π×10
s ≈ (97/360) × 2× 3.14159 × 10
s ≈ 16.975
Therefore, the arc length is approximately 16.975 units.

a dinosaur fossil is 92,170,000 years old. How can you express this age in scientific notation with the highest level of precision?
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]

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]
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'?
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.

a bird is in a tree 30 feet off the ground and drops at Twigs at lands on a rose bush 25 ft below. the function h(t)=-16t^2+30, where T represents the time in seconds gifts the height H and feet of The Twig above the ground as it falls when will The Twig land on the bush
Answer:
After 1.25 seconds the twig land on the bush.
Step-by-step explanation:
Given function that shows the height of twig from the ground after t seconds,
[tex]h(t)=-16t^2+30[/tex]
When twig is on the bush,
h(t) = 5 feet ( ∵ the distance from bush to ground = 30 - 25 = 5 feet )
[tex]\implies -16t^2+30=5[/tex]
[tex]-16t^2=-25[/tex]
[tex]t^2=\frac{25}{16}[/tex]
[tex]\implies t=\pm \frac{5}{4}[/tex]
Since, time can not be negative,
Hence, t = [tex]\frac{5}{4}[/tex] ≈ 1.25
Therefore, after 1.25 seconds the twig land on the bush.
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.
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]
