Answers

Answer 1

Hello!

3/4 = 0.75 as a decimal

We know that Jen picks 0.75 of a gallon of strawberries in half an hour, and now we want to find out how many gallons she'll pick in 2 hours.

Half an hour = 0.5 2 ÷ 0.5 = 4 There are four half hours in 2 hours.

0.75 × 4 = 3

ANSWER:

Jen will have picked 3 gallons of strawberries in 2 hours.

no. when plugging 4 into the equation, 0 is not the final result. instead it is 6.

square root of 2(4)+1 = square root of 9 = 3

3+3 = 6
and 6 is not 0 so x cannot = 4

A student concluded that the solution of the equation [tex]\sqrt{2x+1}+3 = 0[/tex] is x = 4. The conclusion is true.

What is a perfect square?

Perfect squares are those integers whose square root is an integer.

Let x-a be the closest perfect square less than x,

and let x+b be the closest perfect square more than x, then we get x-a < x < x+b (no perfect square in between x-a and x+b, except possibly x itself).

Then, we get:

[tex]\sqrt{x-a} < \sqrt{x} < \sqrt{x+b}[/tex]

[tex]\sqrt{2x+1}+3 = 0\\\\\sqrt{2x+1}= -3[/tex]

by taking square on both sides we get

[tex](\sqrt{2x+1})^2 = (- 3)^2 \\\\2x+ 1 = 9[/tex]

when x = 4

2(4) + 1

= 9

Thus, the solution of the equation is 4.

This is known as a piecewise function. It's a function that depends on what t is valued at. There are three cases

If [tex]0 \ \textless \ t \le 30[/tex] then f(t) = 0. This means that for the first 30 minutes, the cost is $0, in other words the first half hour is free.

If [tex]30 \ \textless \ t \le 90[/tex] then f(t) = 5 indicating that the cost is $5 for the entire span from 30 minutes to 90 minutes (excluding t = 30 but including t = 90). Choice B is not the answer because the cost isn't $5 per minute. The cost for this entire timespan is simply $5

Finally, if t > 90, then f(t) = 10 telling us that any time value over 90 minutes will have the cost be $10. This is why the answer is choice D

Suppose a life insurance company sells a $250,000 one-year term life insurance policy to a 20-year-old female for $320. The probability that the female survives the year is 0.999647. Compute and interpret the expected value of this policy to the insurance company.

Answers

The expected value is equivalent to the current receivable payment minus any potential payouts. The insurance company is assured of the $320 payment they will receive. Then the probability that the female will not survive the year is 1 - 0.999647 = 0.000353. We multiply this probability by the value of $250,000 to get $88.25. Then we subtract $320 - $88.25 to get the expected value of $231.75.

Which rule describes the translation? T–3, –2(x, y) T–3, 2(x, y) T3, –2(x, y) T3, 2(x, y)
SOMEONE PLEASE ANSWER PLEASE

Answers

The rule which describes the translation of the figure is T–3, –2(x, y).

The translation T(x, y) → (x – h, y – k) moves a point (x, y) to a new point (x – h, y – k).

T–3, –2(x, y) moves the point 3 units to the right and 2 units down.

T–3, 2(x, y) moves the point 3 units to the right and 2 units up.

T3, –2(x, y) moves the point 3 units to the left and 2 units down.

T3, 2(x, y) moves the point 3 units to the left and 2 units up.

So the answer is T–3, –2(x, y).

Here is a table that shows the effect of each translation on the point (3, 4):

Original point | Translation | New point

(3, 4) | T–3, –2(x, y) | (0, 2)

The image shows a tape diagram with two sections labeled "You" and "Friend". The "You" section is longer than the "Friend" section, indicating that you tutored for more hours than your friend.

To find the number of hours that you tutored, we can divide the total number of hours tutored (12 hours) by the number of sections in the tape diagram (2).

Number of hours you tutored = 12 hours / 2 sections = 6 hours

Therefore, you tutored for 6 hours.

Explanation of tape diagrams:

A tape diagram is a visual representation of a mathematical equation. It is a horizontal bar that is divided into sections, with each section representing a different quantity. The length of each section represents the size of the quantity it represents.

Tape diagrams can be used to solve a variety of mathematical problems, including addition, subtraction, multiplication, and division problems. They are especially useful for solving problems that involve multiple quantities, as they can help to visualize the relationships between the different quantities.

In this case, the tape diagram is used to solve the following problem:

> You and a friend tutor for a total of 12 hours. Use the tape diagram to find how many hours you tutor.

The tape diagram is divided into two sections, one for you and one for your friend. The length of each section represents the number of hours that each person tutored. Since you tutored for more hours than your friend, the "You" section is longer than the "Friend" section.

To find the number of hours that you tutored, we can divide the total number of hours tutored (12 hours) by the number of sections in the tape diagram (2). This gives us the number of hours that you tutored, which is 6 hours.

Therefore, the answer to the question is "You tutored for 6 hours."

given the conversion factor 3.28 ft/ 1m which cube above has the larger surface area

cube A is 7’ cube b is 2m

Answers

The first thing that we are going to do in passing everything to the same unit.
We have then:
Cube A:
7 * (1 / 3.28) = 2.13 m
Cube B:
2 m
The surface area of a cube is:
A = 6 * L ^ 2
Where,
L: side
Since cube A has a longer side (2.13m) then it will have the largest surface area.
Answer:
Cube A has the larger surface area

Final answer:

After converting Cube B's side length to feet, Cube A has a surface area of 294 ft² while Cube B has a surface area of 258.2016 ft², making Cube A the one with the larger surface area.

Explanation:

To determine which cube has the larger surface area, we must work with a common unit of measurement for both cubes. We'll convert Cube B from meters to feet using the conversion factor 3.28 ft/1m.
For Cube A with a side length of 7 feet, the surface area (SA) is calculated by the formula SA = 6 × s² (where 's' is the side length).
SA (Cube A) = 6 × (7 ft)² = 6 × 49 ft² = 294 ft².
For Cube B with a side length of 2 meters, we first convert meters to feet: 2 m × 3.28 ft/m = 6.56 ft. So, the surface area of Cube B becomes:
SA (Cube B) = 6 × (6.56 ft)² = 6 × 43.0336 ft² = 258.2016 ft².
Between Cube A and Cube B, Cube A has the larger surface area.

The difference of the squares of two positive consecutive even integers is 76. find the integers. use the fact that, if x represents an even integer, then x+2 represents the next consecutive even integer.

Answers

Write an equation based on the problem
(x + 2)² - x² = 76

We should find the value of x to know the smaller integer.
(x + 2)² - x² = 76
simplify the quadratic expression for (x + 2)²
(x + 2)² - x² = 76
(x + 2)(x + 2) - x² = 76
x² + 2x + 2x + 4 - x² = 76
x² - x² + 4x + 4 = 76
4x + 4 = 76

Solve for x
4x = 76 - 4
4x = 72
x = 72/4
x = 18

Find the bigger integer
x + 2 = 18 + 2 = 20

Final answer:

The two positive consecutive even integers that, when their squares are subtracted, equal 76 are 18 and 20.

Explanation:

In this problem, the two positive consecutive even integers can be represented as x and x+2. The problem states that the difference of their squares is 76, which can be put into the equation (x + 2)^2 - x^2 = 76. By simplifying this equation, we get 4x + 4 = 76.

The area of the rectangle shown is given by the function A(x) = 2x2 - 5x. If the width of the rectangle is 13, what is the area

Answers

If the width of the reactangle is x=13, the area of the rectangle is:
A(13)=2*(13)^2-5*(13)
A(13)=2*(169)-65
A(13)=338-65
A(13)=273

The area of the rectangle is 273 square units

The area of the rectangle is 273 square units.

The task is to find the area of a rectangle where the width of the rectangle is given as 13, and the area as a function of x is provided as A(x) = 2x² - 5x.

To find the area, we need the value of x that corresponds to the width. Since the width is 13, we set x as 13 and substitute it into the area function.

A(13) = 2(13)² - 5(13) = 2(169) - 65 = 338 - 65 = 273 square units.

Thus, the area of the rectangle is 273 square units.

What is Quadratic equation?

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. First, there must be a term other than zero in the coefficient of x²(a>0) for an equation to be a quadratic equation. The x² term is written first when constructing a quadratic equation in standard form, then the x term, and finally the constant term. The numerical values of a, b, and c are often expressed as integral values rather than fractions or decimals.

Given Equation:

h(t) = –16t² + 14t

For the Hangout time we can consider the function h(t)=0

0 = –16t² + 14t

16t² = 14t

16t= 14
