Joseph is reading a 32 page book he read 6 pages in 15 minutes if he continues to read at the same rate how long will it take him to read the entire book
Answer:
80 minutesssssss
Answer:
(edit) your answer is 80 min
Step-by-step explanation:
first we can set this up as a proportion.
so it would be 15 over 6 and your other side would be x over 32
so when u cross multiple your equation would be 6x = 480
then you divide both sides by 6 and when you divide 480 by 6 u will get 80

A store had 250 bottles of water. Each week, 40% of the bottles were sold and 48 new bottles arrived in shipments.
Which recursive function best represents the number of bottles of water in the store, given that f(0) = 250?
A. f(n) = f(n − 1) ⋅ 0.6 + 48, n > 0
B. f(n) = 250 − f(n − 1) ⋅ 0.4 + 48, n > 0
C. f(n) = f(n − 1) ⋅ 0.4 + 48, n > 0
D. f(n) = 250 − f(n − 1) ⋅ 0.6 + 48, n > 0
pls give reason
Answer:
A
Step-by-step explanation:
Given:
Initial number of bottles = 250
Every week = 40% is sold and 48 bottles arrive.
Week 1 = 250 - (250 x 0.40) + 48 = 250 - 100 + 48 = 198
Week 2 = 198 - (198 x 0.40) + 48 = 198 - 79 + 48 = 167
Answer is: A. f(n ) = f(n - 1) • 0.6 + 48, n > 0.
Use a matrix equation to solve the system of linear equations. left brace Start 2 By 1 Matrix 1st Row 1st Column 2nd Row 1st Column EndMatrix x plus 2 y equals 8 nbsp 2 x plus 6 y equals 9 What is the inverse matrix?
Answer:
[tex]\left[\begin{array}{ccc}3&-1&\\-1&1/2\\\end{array}\right][/tex]
Step-by-step explanation:
The matrix system for the linear equations: x + 2y = 8, 2x + 6y = 9
[tex]\left[\begin{array}{ccc}1&2&\\2&6\\\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}8\\9\end{array}\right][/tex]
To get the coefficient of x and y, the inverse of the first matrix (let the first matrix be A) must be known.
[tex]A^{-1}[/tex] = (1 / determinant of A) x Adjoint of A
the determinant of A = (1 x 6) - (2 x 2) = 6 - 4 = 2
Adjoint of A = [tex]\left[\begin{array}{ccc}6&-2&\\-2&1\\\end{array}\right][/tex]
[tex]A^{-1}[/tex]= [tex]\frac{1}{2} \left[\begin{array}{ccc}6&-2\\-2&1\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}3&-1&\\-1&1/2\\\end{array}\right][/tex]

What is the fraction 24/4 simplified?
Answer:
6
Step-by-step explanation:
The fraction 24/4 simplified is 6.
To simplify the fraction 24/4, we find the greatest common divisor (GCD) of the numerator (24) and the denominator (4), and then divide both the numerator and denominator by the GCD to obtain the simplified form.
Step 1: Find the GCD of 24 and 4.
The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.
The factors of 4 are 1 and 4.
The GCD of 24 and 4 is 4, as it is the largest number that divides both 24 and 4.
Step 2: Divide both the numerator and denominator by the GCD.
24 ÷ 4 = 6
4 ÷ 4 = 1
So, the simplified form of 24/4 is 6/1. However, any fraction divided by 1 remains the same, so the simplified fraction is 6.
Therefore, 24/4 simplified is 6.

a candle is burning at a linear rate. The candle measures five inches two minutes after it was lit. It measures three inches eight minutes after it was lit. What was the original length of the candle?
Answer:
5 2/3 inches.
Step-by-step explanation:
8-2=6 minutes and 5-3=2 inches so it lost 2 inches in 6 minutes. This means it loses an inch every three minutes. Since we have to go back by 2 minutes we will have to figure out how much length we have to add to the candle to figure out how long it was originally by multiplying by 2/3 as 2 inches is 2/3 the required to remove an inch, so 1 inch * 2/3 = 2/3 of an inch. Add that to the length at two minutes and we have 5 2/3 inches as its original size.

A person who weighs 105 pounds on Earth weighs 175 pound on the moon How much does a pound person weigh on the moon?
Answer:
1.67 pounds
Step-by-step explanation:
The problem above can be solved by using "direct proportion." This proportion shows that as one quantity increases, the other quantity increases and vice-versa.
Step 1: Represent the weight of the person on the moon by n.
Step 2: Set up a proportion.
[tex]\frac{105}{175}[/tex] = [tex]\frac{1}{n}[/tex]
Step 3: Cross multiply.
105 x n = 175 x 1
105n = 175
Step 4: Find n by dividing both sides by 105.
n = [tex]\frac{175}{105}[/tex]
n = 1.666 or 1.67 pounds (lowest term)
A pound of person on Earth will weigh 1.67 pounds on the moon.

a city has a garden in the shape of an equilateral triangle with 40 feet sides. there is a walkway that runs from a gate located at the midpoint of one side of the equilateral triangle to a fountain at the opposite vertex. approximately how long is the walkway?
Answer:
The walkway is approximately 34.64 feet long
Step-by-step explanation:
The length of the sides of the equilateral triangle shaped the city garden = 40 feet
The path of the walkway = From the midpoint of a side to the opposite vertex
Therefore, we have;
Let x, represent the length of the walkway
We have that the x, a side of the equilateral triangle, and half the side of the location of the gate, forms a right triangle, with a side of the equilateral triangle representing the hypotenuse side
Therefore, we have;
40² = x² + (40/2)²
40² = x² + 20²
x² = 40² - 20² = 1200
x = √1200 = 20·√3
The length of the walkway = x = 20·√3 ≈ 34.64 feet.

Recall that negative exponents indicates that we need to move the base to the other side of the fraction line.
(The "1's" in the simplifications above are for clarity's sake, in case it's been a while since you last worked with negative powers. One doesn't usually include them in one's work.)
In the context of simplifying with exponents, negative exponents can create extra steps in the simplification process.

Length = x m
Width = 3⅔ = 11/3
Area = 44 m²
Area of rectangle = length × width
Plug in the values into the equation
[tex] 44 = x \times \frac{11}{3} [/tex]
[tex] 44 = \frac{11x}{3} [/tex]
Multiply both sides by 3

Answer:
[tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
We can use the rise over run method to do this question.
Let's start at the coordinates (1,1)
If we go down 2 from that point and to the right 3 times then we see another point on the line (3, -1).
We would express this as 2 over 3 or [tex]\frac{2}{3}[/tex].
We aren't done yet however.
The line is sloping downwards and this means that the slope is negative.
So, the final answer is [tex]-\frac{2}{3}[/tex]
