The code to unlock a safety deposit box is three consecutive odd integers whose sum is 75. Find the integers
Answer: The integers are 23, 25, and 27
Step-by-step explanation:
Call the first integer n, and then the next two odd ones are n + 2 and n + 4.
Add them together to get 75:
n + n+ 2 + n + 4 = 75
which becomes 3n + 6 = 75
so 3n = 69, and n is therefore 23. n + 2 = 25, and n + 4 = 27.
The three consecutive odd integers whose sum is 75 are 23, 25, and 27. These are determined by forming an equation with the first odd integer as 'x' and the other two as 'x+2' and 'x+4', respectively, since consecutive odd numbers differ by 2.
The task is to find three consecutive odd integers whose sum is 75. To solve this, we can represent the three consecutive odd integers as x, x + 2, and x + 4. Since the sum of these integers is 75, we can set up the following equation: x + (x + 2) + (x + 4) = 75.
Simplifying the equation we get:
3x + 6 = 75
3x = 69
x = 23
Now we have our first integer x = 23. The next consecutive odd integer would be x + 2 which is 25, and the third one would be x + 4 which is 27. Therefore, the three consecutive odd integers that sum up to 75 are 23, 25, and 27.
What is the length of the intercepted arc?
First you need to calculate the circumference of the circle:
Circumference = diameter x PI = 16 x PI = 16 * 3.14 = 50.24
The intercepted arc is 15 degrees.
To find the length multiply the circumference by the central angle divided by 360.
Arc length = 50.25 x (15/360) = 2.1 units.
The stem and leaf plot below could not represent which of the following
The stem and leaf plot below could not represent "the weight of phonebooks, in pounds".
The stem-and-leaf plot you've provided represents a dataset, but without specific labels for the data points, it's challenging to definitively assign the plot to a particular category. However, we can analyze the options you've provided.
1. **Average number of inches of rain in June:** The data points don't seem to represent rainfall values. Rainfall would typically be measured in fractions or decimals, not whole numbers like 33.
2. **Height of plant seedlings, in inches:** This is a possibility, especially if the numbers represent the height of seedlings in inches. The decimal point represented by the key (3 | 5 means 3.5) supports this interpretation, indicating a measurement in inches.
3. **Weight of phonebooks, in pounds:** Phonebook weights are usually measured in pounds or ounces. The given numbers do not correspond to common weights and are unlikely to represent phonebook weights.
4. **Height of NBA basketball players, in meters:** NBA player heights are typically measured in feet and inches, not meters. Additionally, the provided numbers do not align with typical heights of NBA players.
Given the context of the data and the presence of the decimal point in the key, it's most likely that the stem-and-leaf plot represents the **height of plant seedlings, in inches.** This interpretation is consistent with the format of the data and the provided key, suggesting measurements in inches.
So, the correct answer is "the weight of phonebooks, in pounds".

A coffee shop recently sold 20 drinks, including 8 mochas. Considering this data, how many of the next 95 drinks sold would you expect to be mochas?
Answer:
38 mochas
Step-by-step explanation:
Of the 20 drinks sold, 8 were mochas, so
8/20 = 0.4 = 40% of the drinks they sold were mochas.
If the sold 95 drinks, then 95(0.4) = 38 of them would be mochas if the proportion stays the same

Gabriella uses 8.4 pints of white paint and blue paint to paint her bedroom walls.
2/5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer:
8
Step-by-step explanation:
covert 8.4 into a fraction which would be 42/5
then subtract 42/5 from 2/5 and youll get 8
Final answer:
To calculate the amount of blue paint Gabriella used, multiply 8.4 pints by 2/5 to determine the white paint, and then subtract this from the total, resulting in 5.04 pints of blue paint.
Explanation:
Gabriella uses a total of 8.4 pints of paint to paint her bedroom walls, with 2/5 of this amount being white paint. To find out how many pints of blue paint she used, we first need to determine the amount of white paint and then subtract that from the total.
Multiply the total amount of paint by 2/5 to find the white paint: 8.4 pints imes 2/5 = 3.36 pints (white paint).
To find the blue paint, subtract the white paint from the total paint: 8.4 pints - 3.36 pints = 5.04 pints (blue paint).
Therefore, Gabriella used 5.04 pints of blue paint to paint her bedroom walls.

i think they were multiplying each by 4. so 6x4 would be 24. and 12x4 = 48, then 15x4= 60. so i believe the blanks are 24,12,60.
Answer:
x y
6 24
9 36
12 48
15 60
Step-by-step explanation:
We need to find the rate of change in the table.
Lets start with the x-values.
6 to 9?
9 - 6 = 3
So, the rate of change in the x-value is 3
9 to 3 is 12
12 to 3 is 15
Now let's go onto the y-values.
We don't know the first number, so let's move to the next number, 36.
36 to 48?
48 - 36 = 12
Therefore, the rate of change in the y-value is 12
So, let's work backwards to find the first number.
36 - 12 = 24
48 + 12 = 60
Another easier way you could do it (really simple).
9 times what is 36?
9 x 4 = 36, right?
So, the change of rate is 4
So multiply everything in the x column by 4.
6 x 4 = 24
15 x 4 = 60
Since we don't have one the x value for 48, divide it by 4 which is 12

simplify b^10/b^2, help me pls
Answer:
[tex]\text{\bf{A.}}\quad b^8[/tex]
Step-by-step explanation:
It may be helpful to remember that an exponent signifies repeated multiplication:
b¹⁰ = b·b·b·b·b·b·b·b·b·b . . . . . . . b is a factor 10 times
and
b² = b·b . . . . . . . . . . . . . . . . . . . . b is a factor 2 times
Then the division can be simplified by using the denominator factors to cancel 2 of the numerator factors:
[tex]\dfrac{b\cdot b\cdot b\cdot b\cdot b\cdot b\cdot b\cdot b\cdot b\cdot b}{b\cdot b}=b\cdot b\cdot b\cdot b\cdot b\cdot b\cdot b\cdot b=b^8[/tex]

Select all expressions that are equivalent to -36x+54y-90
The equivalent expressions of -36x+54y-90 are -18(2x - 3y + 5), 18(-2x + 3y - 5), and -2(18x - 27y + 45). So options (2), (4) and (5) are correct.
To determine which expressions are equivalent to -36x + 54y - 90, we'll distribute the coefficients and compare the resulting expressions.
Let's start by distributing each expression:
1. -9(4x - 6y - 10) = -36x + 54y + 90
2. -18(2x - 3y + 5) = -36x + 54y - 90
3. -6(6x + 9y - 15) = -36x - 54y + 90
4. 18(-2x + 3y - 5) = -36x + 54y - 90
5. -2(18x - 27y + 45) = -36x + 54y - 90
6. 2(-18x + 54y - 90) = -36x + 108y - 180
Among these, expressions 2, 4, and 5 result in the same expression as -36x + 54y - 90.
Expression 2 is -18(2x - 3y + 5), expression 4 is 18(-2x + 3y - 5), and expression 5 is -2(18x - 27y + 45).
Therefore, the equivalent expressions are -18(2x - 3y + 5), 18(-2x + 3y - 5), and -2(18x - 27y + 45).
If a certain number is added to the numerator and denominator of 8/11, the result is 6/7. Find the number.
Answer:
x = 10
Step-by-step explanation:
8 + x = 6
11 + x 7
Cross Multiply
6(11 + x) = 7(8 + x)
66 + 6x = 56 + 7x
10 = x
The number that needs to be added to the numerator and denominator of 8/11 to result in 6/7 is 10.
Explanation:The subject of the question is Mathematics, specifically algebra and fractions. We can represent the student's problem with an equation, where x stands for the unknown number to be added to the numerator and denominator of 8/11 to get 6/7.
The initial fraction is 8/11 and the desired fraction is 6/7. Hence, we can translate this problem into the equation: (8 + x)/(11 + x) = 6/7. By cross-multiplying to eliminate the fractions, we get: 7(8 + x) = 6(11 + x). Simplified, this equation becomes 56 + 7x = 66 + 6x. Solving for x, we subtract 6x from both sides: x = 66 - 56, so x = 10.

Complete the square to determine the maximum or minimum value of the function defined by the expression. x2 + 8x + 6 A) minimum value at 8 B) maximum value at 10 C) minimum value at −14 D) minimum value at −10
Answer:
[tex]\large\boxed{\text{ D) minimum value at -10}}[/tex]
Step-by-step explanation:
[tex]\text{The vertex form of equation}\ y=ax^2+bx+c:\\\\y=a(x-h)^2+k\\\\\text{We have the equation:}\ y=x^2+8x+6.\\\\a=1>0,\ \text{the parabola is o}\text{pen up.}\\\text{Therefore the function has the minimum in vertex}\\\\x^2+8x+6=x^2+2(x)(4)+6=x^2+2(x)(4)+4^2-4^2+6\\\\\text{use}\ (a+b)^2=a^2+2ab+b^2\to x^2+2(x)(4)+4^2=(x+4)^2\\\\y=(x+4)^2-16+6=(x+4)^2-10\to\text{vertex}\ (-4,\ -10).[/tex]
To determine the minimum value of the quadratic function x^2 + 8x + 6, we complete the square to get the expression (x + 4)^2 - 10 = 0. The function has a minimum value at (x, y) = (-4, -10), so the correct answer is D) minimum value at -10.
Explanation:To find the maximum or minimum value of the quadratic function given by the expression x2 + 8x + 6, we need to complete the square. First, we will write the quadratic in the form of (x + h)2 + k, where h and k are constants.
The coefficient of x is 8. We take half of it, which is 4, and square it to get 16. Now add and subtract this square inside the quadratic expression:
x2 + 8x + 16 - 16 + 6 = 0
Now, group the perfect square trinomial and write it as a square of a binomial:
(x + 4)2 - 10 = 0
To find the minimum value, we set the squared term equal to zero, since the minimum value of a square is zero. As such, (x + 4)2 reaches its minimum value when x = -4, and the overall minimum value of the function is when k = -10. Because this is a quadratic with a positive leading coefficient, the function has a minimum value, not a maximum.
Therefore, the correct answer is D) minimum value at -10.
