Answer:
The length of the other piece is 385 cm or 3 m 85 cm.
Step-by-step explanation:
Given that,
The length of the string = 6 m 50 cm
He cut it into 2 pieces.
Length of first piece = 265 cm
6 m 50 cm = 600 cm + 50 cm
= 650 cm
Length of another piece = 650 cm - 265 cm
= 385 cm
or
= 3 m 85 cm
So, the length of the other piece is 385 cm or 3 m 85 cm.

Answer:
A real world situation could be: Holden is walking to school for his basketball game.
He lives 10 blocks from school. Holden walks 6 blocks in 4 minutes, but then realizes that he forgot his jersey. He runs back home in 2 minutes and spends 2 minutes finding his jersey at home. Finally, he runs 5 blocks every 2 minutes until he reaches school. And a good example/photo would be: (down below)

y=-3x+5
5x-4=-3
solve for x and y
Answer:
y = 4.4
x = 1/5
Step-by-step explanation:
5x -4 = -3
5x -4 +4 = -3 +4
5x = 1
x = 1/5
y = -3(1/5) + 5
y = 4.4

Suppose that the relation S is defined as follows. S= {(4,9), (-9,4), (0, -9), (6, 6)} Give the domain and range of S. Write your answers using set notation.
domain =
range =
Given:
The relation S is:
[tex]S=\{(4,9),(-9,4),(0,-9),(6,6)\}[/tex]
To find:
The domain and range of S.
Solution:
If a relation is defined by the set of ordered pairs (x,y), then the domain is the set of x-values and range is the set of y-values.
Let R be a relation defined as [tex]R=\{(x,y):x\in R,y\in R\}[/tex], then [tex]Domain=\{x:x\in R\}[/tex] and [tex]Range=\{y:y\in R\}[/tex].
The given relation is:
[tex]S=\{(4,9),(-9,4),(0,-9),(6,6)\}[/tex]
Here, x-values are 4,-9,0,6 and the y-values are 9,4,-9,6.
So, the domain and range of the given relation S are
[tex]Domain=\{-9,0,4,6\}[/tex]
[tex]Range=\{-9,4,6,9\}[/tex]
Therefore, [tex]Domain=\{-9,0,4,6\}[/tex] and [tex]Range=\{-9,4,6,9\}[/tex].
A research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n=918 and x=521 who said "yes." Use a 90% confidence level.
B) Identify the value of the margin of error E.
C) construct the confidence interval.
Answer:
B) The margin of error is 0.0269.
C) The confidence interval is (0.5406, 0.5944).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In the poll, n=918 and x=521 who said "yes."
This means that [tex]n = 918, \pi = \frac{521}{918} = 0.5675[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
B) Identify the value of the margin of error E.
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]M = 1.645\sqrt{\frac{0.5675*0.4325}{918}} = 0.0269[/tex]
The margin of error is 0.0269.
C) construct the confidence interval.
[tex]\pi \pm M[/tex]
So
[tex]\pi - M = 0.5675 - 0.0269 = 0.5406[/tex]
[tex]\pi + M = 0.5675 + 0.0269 = 0.5944[/tex]
The confidence interval is (0.5406, 0.5944).
A water tank already contains 55 gallons of water when Baxter begins to fill it. Water flows into the tank at a rate of 8 gallons per minute. Write a linear equation to model this situation. Find the volume of water in the tank 25 minutes after Baxter begins filling the tank.
Answer:
y=8x+55
255 gallons
Step-by-step explanation:
Linear equation: y=mx+b
In this equation you can go ahead and start off with your Y intercept (b) which is where you begin and you begin with 55 gallons. As for the m and x section in the linear equation your m is how much it increases at a constant rate in a minute and that will be eight so you can go ahead and put 8 and then X which is the amount of minutes.
To figure out how many gallons there are in 25 minutes you can use the same equation so you can multiply 8 which is the amount of gallons per minute * 25 and that gives you 200 then you can go ahead and add the y-intercept which is 55 and that gives you 255 gallons in 25 minutes.

Let f be a continuous function on the closed
interval [0, 2] . If 2 (less than ir equal to) f(x) (less than or equal to) 4, then the greatest
possible value of (integral from 0 to 2)f(x)dx is
a. 0
b. 2
c. 4
d. 8
e. 16
Answer:
D) 8
Step-by-step explanation:
We are given a continuous function f on the closed interval [0, 2].
Where:
[tex]2\leq f(x)\leq 4[/tex]
And we want to find the greatest possible value of:
[tex]\displaystyle \int_0^2f(x)\,d x[/tex]
The range restriction tells us that even if f(x) = 2 for all x in the interval [0, 2], the smallest area possible will be 4, since that is the area of the rectangle.
Then in that case, the maximum possible value of the integral must be 8. f(x) cannot exceed 4, and the length of the interval is two units. Thus, the greatest possible value of the integral is 8. This will only occur if f(x) is a horizontal line at y = 4 from x = 0 to x = 2.

a 60-ounce bottle of soda cost $1.20 at the grocery store.A 20-ounce bottle of soda cost $1.00.
Answer:
Well assuming you mean which will be the better option it would be the 60 ounce and 1.20 option. Since if you find the unit rate for that you’d only get 0.02 dollars for each ounce of soda. And for the 20 ounce one you’d get 0.05 dollars per ounce. The better option is the 60 ounces bottle for 1.20.

Answer:
y = -2/5x +36/5 . . . . . slope-intercept form
2x +5y = 36 . . . . . . . . standard form
Step-by-step explanation:
You can use the 2-point form of the equation of a line to find it.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (4 -6)/(8 -3)(x -3) +6
y = -2/5(x -3) +6
y = -2/5x +36/5 . . . . slope-intercept form
2x +5y = 36 . . . . . . . standard form

The pair of figures to the right are similar. Compare the first figure to the second. Give the ratio of the perimeters and the ratio of the areas .
Given:
The pair of similar triangles.
Base of smaller triangle = 10 in
Base of larger triangle = 14 in
To find:
The ratio of the perimeters and the ratio of the areas.
Solution:
Ratio of perimeter of similar triangles is equal to the ratio of their corresponding sides.
[tex]\text{Ratio of perimeters}=\dfrac{10\ in.}{14\ in.}[/tex]
[tex]\text{Ratio of perimeters}=\dfrac{5}{7}[/tex]
[tex]\text{Ratio of perimeters}=5:7[/tex]
The ratio of area of similar triangles is equal to the ratio of squares of their corresponding sides.
[tex]\text{Ratio of areas}=\dfrac{(10)^2}{(14)^2}[/tex]
[tex]\text{Ratio of areas}=\dfrac{100}{196}[/tex]
[tex]\text{Ratio of areas}=\dfrac{25}{49}[/tex]
[tex]\text{Ratio of areas}=25:49[/tex]
Therefore, the ratio of the perimeters is 5:7 and the ratio of the areas 25:49.

Let O be a quadrant I angle with cos(0) ✓11/7 Find sin(20).
Answer:
[tex]\displaystyle \sin(2\theta)=\frac{2\sqrt{418}}{49}\approx0.8345[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \cos(\theta)=\frac{\sqrt{11}}{7}[/tex]
Where θ is in QI.
And we want to determine sin(2θ).
First, note that since θ is in QI, all trig ratios will be positive.
Next, recall that cosine is the ratio of the adjacent side to the hypotenuse. Therefore, the adjacent side a = √(11) and the hypotenuse c = 7.
Then by the Pythagorean Theorem, the opposite side to θ is:
[tex]b=\sqrt{(7)^2-(\sqrt{11})^2}=\sqrt{49-11}=\sqrt{38}[/tex]
So, with respect to θ, the adjacent side is √(11), the opposite side is √(38), and the hypotenuse is 7.
We can rewrite as expression as:
[tex]\sin(2\theta)=2\sin(\theta)\cos(\theta)[/tex]
Using the above information, substitute. Remember that all ratios will be positive:
[tex]\displaystyle =2\Big(\frac{\sqrt{38}}{7}\Big)\Big(\frac{\sqrt{11}}{7}\Big)[/tex]
Simplify. Therefore:
[tex]\displaystyle \sin(2\theta)=\frac{2\sqrt{418}}{49}\approx0.8345[/tex]
A vat holds 100 cubic feet of liquid and is initially full. Liquid which is salt water with 1 gram of salt per 2 cu ft of liquid is being added at a rate of 2 cu ft per minute. It is mixed immediately, and the mixture is draining at 2 cu ft per minute, so the vat stays exactly full. Let y(t) denote the number of grams of salt in the vat at time t. Write the differential equation for y. Use the graphical method to plot two substantially different solutions for y, depending on the initial amount. Explain the difference. Then use the formula for solution of first-order linear DE to write the explicit solution if the vat is initially filled with pure water (i.e., no salt).
Answer:
