a rope is sq rt. 250 units long. If cut into 2 pieces so that the lengths of the pieces are in the ratio of 3:2 what is the length of longer piecein simplest radical form? 3:2 =5/3(?) Do i set x/sq.rt.250=5/3? I end up with 25 sq rt. 10/3. This isn't correct.
Let 3x = the length of the first rope
2x = the length of the second rope
This representation is based on the given that the ratio of the two ropes is 3:2.
3x + 2x = sq rt. 250
5x = sq rt. 250
x = sq rt. 250 / 5
x = sq rt. 25(10) / 5
x = 5 sq rt. 10 /5

Input in standard form the equation of the given line. The line with m=1/2 and b=3
Final answer:
To find the equation of a line with a given slope and y-intercept in standard form, substitute the values of the slope and y-intercept into the equation y = mx + b.
Explanation:
To write the equation of a line given the slope m and y-intercept b in standard form y = mx + b, you can directly substitute the values of m = 1/2 and b = 3 into the equation.
Substitute m = 1/2 and b = 3 into y = mx + b: y = (1/2)x + 3
Therefore, the equation of the line in standard form is y = (1/2)x + 3.

If you make random guesses for 10 multiple-choice test questions (each with five possible answers), what is the probability of getting at least 1 correct? if a very lenient instructor says that passing the test occurs if there is at least one correct answer, can you reasonably expect to pass by guessing?
The probability of getting at least 1 correct answer when guessing on a multiple-choice test can be found by subtracting the probability of getting all answers wrong from 1. Whether it is reasonable to expect to pass by guessing depends on the passing percentage and the probability of getting at least 1 answer correct.
Explanation:To find the probability of getting at least 1 correct answer when making random guesses for 10 multiple-choice test questions, we can look at the probability of getting 0 correct and subtract it from 1. Since each question has 5 possible answers, the probability of getting a question wrong is 4/5. So the probability of getting all 10 questions wrong is (4/5)^10. Therefore, the probability of getting at least 1 correct answer is 1 - (4/5)^10.
To determine if you can reasonably expect to pass the test by guessing, we need to compare the probability of getting at least 1 correct answer to the passing percentage. If the probability of passing is higher than the passing percentage, then it is reasonable to expect to pass by guessing.

What is an equivalent expression to 4+3(5+x)
Finish the steps below to write a quadratic function for the parabola shown. Use the vertex form, f(x) = a(x – h)2 + k, and substitute in the values for h and k. f(x) = a(x – 5)2 + 3 Use another point and substitute in values for x and f(x). Solve for a. 5 = a(6 – 5)2 + 3 Write the function, using the values for h, k, and a. The function is f(x) = (x – )2 + .
Here we want to write the quadratic function for the parabola shown in vertex form.
We will get the function: f(x) = 2*(x - 5)^2 + 3
So the general function of a parabola with vertex (h, k) and leading coefficient a is:
f(x) = a*(x - h)^2 + k
Here, we know the formula:
f(x) = a*(x - 5)^2 + 3
where:
h = 5k = 3So the vertex is the point (5, 3), and we only must find the value of a to completely determine the parabola's function
We also know that:
f(6) = 5
So we can solve:
5 = a*(6 - 5)^2 + 3
5 = a*(1)^2 + 3
5 = a + 3
5 - 3 = a = 2
So we just found the value of a, replacing this on the parabola's function we get:
f(x) = 2*(x - 5)^2 + 3

Annabella spends $2.25 per gallon on gas at the gas station. After driving a certain distance, she stops at a second gas station and spends $2.15 per gallon on gasoline. Annabella can express her average cost per gallon of gasoline as 2.25x+2.15(x+5)/2x+5 .
Answer:
THE NUMERATOR OF THE RATIONAL EXPRESSION REPRESENTS THE TOTAL COST OF GASOLINE PURCHASED.
THE DENOMINATOR OF THE RATIONAL EXPRESSION REPRESENTS THE TOTAL GALLONS OF GASOLINE PURCHASED
The complete problem is:
Annabella spends $2.25 per gallon on gas at the gas station. After driving a certain distance, she stops at a second gas station and spends $2.15 per gallon on gasoline.
Annabella can express her average cost per gallon of gasoline as [tex]y = \frac{(2.25x + 2.15(x+5))}{2x+5}[/tex]
What is the meaning of the parts of this rational expression in the context of the situation?
THE NUMERATOR OF THE RATIONAL EXPRESSION REPRESENTS THE __________.
(select one)
1. total cost of the gasoline purchased
2. total number of gallons of gasoline purchased
3. cost per gallon of gasoline
THE DENOMINATOR OF THE RATIONAL EXPRESSION REPRESENTS THE ________.
1. total cost of the gasoline purchased
2. total number of gallons of gasoline purchased
3. cost per gallon of gasoline
So, in this context and based on the given data, the numerator of the expression is referring to the total cost of gasoline purchased, and the denominator is expressing the total gallons of gasoline purchased.
You can deduct this because, the numerator contains the amounts of costs per gallon, being x gallons. On the other hand, you can see in the denominator that there's no costs multiplying the variable, it's just a quantity which refers to the amount of gasoline, not the cost.
Find the volume of a box that will hold nine 9.425 cm3 cylindrical containers that each measure 3 centimeters long. (round to nearest whole number)
Final Answer:
The volume of the box that will hold nine 9.425 cm³ cylindrical containers, each measuring 3 centimeters long, is approximately 108 cm³.
Explanation:
First, we need to find the radius of each cylindrical container since we have its volume and the length. The volume V of a cylinder is given by the formula:
[tex]\[ V = \pi r^2 h \][/tex]
where r is the radius and h is the height (or length) of the cylinder. We are given:
[tex]\[ V = 9.425 \text{ cm}^3 \\\\\[ h = 3 \text{ cm} \][/tex]
We need to solve for r:
[tex]\[ 9.425 = \pi r^2 (3) \\\\\[ r^2 = \frac{9.425}{3\pi} \\\\\[ r^2 = \frac{9.425}{3 \times 3.14159} \\\\\[ r^2 = \frac{9.425}{9.42477} \\\\\[ r^2 \approx 1 \\\\\[ r \approx 1 \text{ cm} \][/tex]
Now we know the radius of one cylindrical container is approximately 1 cm. Although this rounding might lead to a slightly inaccurate result, we'll proceed with this approximation for simplicity's sake.
Since each container is a cylinder with a radius of 1 cm, the diameter of each container is [tex]\( 2 \times 1 = 2 \)[/tex] cm. If we wanted to pack these containers without any wasted space in one layer, we would arrange them in a 3 by 3 grid, given there are 9 containers. The length and the width of the box would then each be 3 times the diameter of one container.
Hence:
Length of box = Width of box = [tex]\( 3 \times 2 \)[/tex] cm = 6 cm.
The height of the box would be equal to the length of one of the containers, which is 3 cm.
Now we can find the volume of the box:
Volume of box [tex]\( V_{\text{box}} \) = Length \( \times \) Width \( \times \) Height[/tex]
[tex]\[ V_{\text{box}} = 6 \text{ cm} \times 6 \text{ cm} \times 3 \text{ cm} \\\\\[ V_{\text{box}} = 36 \text{ cm}^2 \times 3 \text{ cm} \\\\\[ V_{\text{box}} = 108 \text{ cm}^3 \][/tex]
Rounding to the nearest whole number, the volume of the box that will hold nine 9.425 cm³ cylindrical containers, each measuring 3 centimeters long, is approximately 108 cm³.

Rachel pays $131.44 for a desk, including tax. The task is 31 cents less than 1*16 the desk’s price. What is the price for the desk before adding the tax?
Answer:
The cost of the desk is 124 dollars.
Step-by-step explanation:
irst, change this into an equation
tax=1/16x-.31
x equals the cost of the desk without tax:
x+tax=131.44
tax=131.44-x
Set the first equation equal to the second:
1/16x-.31=131.44-x
Solve for x:
17/16x=131.75
x=$124
Hope that helps
The equivalent percentage value for the decimal number 1.16 is 116% which is obtained by multiplying the decimal by 100. Before including the tax the price of the desk was $60.99.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
And to convert a fraction or a decimal into percentage, they are multiplied by 100.
Given that,
The amount paid by Rachel for a desk is $131.44.
Suppose the price of desk is before adding the tax is x.
Then, as per the problem the following expression can be written for the tax amount as,
1.16x - 0.31
Now, the expression for the price of desk after tax is,
x + 1.16x - 0.31 = 131.44
⇒ 2.16x = 131.44 + 0.31
⇒ 2.16x = 131.75
⇒ x = 131.75 / 2.16
⇒ x = 60.99
Hence, the price for the desk before adding the tax is $60.99.
