Answer: The answer is -28
Step-by-step explanation:
Trust me
Final answer:
The integer representing the temperature drop of 28°, leaving the thermometer at 48°, is -28. The original temperature before the drop was 76°.
Explanation:
The integer that represents the number of degrees the temperature drops when the temperature drops 28° and the thermometer reads 48° afterwards is -28. To find this, we use the final temperature (48°) and add the temperature drop (28°) to determine the original temperature. However, since it is a temperature drop, we have to add a negative sign to the drop, making it -28°. Therefore, the original temperature was 48° + 28° = 76°. The decrease in temperature is represented by the negative integer -28°.
Manuel spent a total of $40 at the grocery store. Of this amount, he spent $36 on fruit. What percentage of the total did he spend on fruit?
Final answer:
Manuel spent 90% of his total grocery expenses on fruit. To calculate this, the amount spent on fruit ($36) is divided by the total spent ($40), and then multiplied by 100%.
Explanation:
Manuel spent a total of $40 at the grocery store and out of that, $36 was spent on fruit. To find out the percentage that he spent on fruit, you can use the formula:
Percentage = (Amount spent on fruit / Total amount spent) x 100%
Plugging in the values gives us:
Percentage = ($36 / $40) x 100% = 0.9 x 100% = 90%.
Thus, Manuel spent 90% of his total grocery expenses on fruit.

Each floor in the old headquarters of Oldham Bank and Trust is 14 feet in
height except the ground floor, which is 24 feet high. There are 5 floors. How
tall is the building?
To find the total height of the building, we need to calculate the sum of the heights of all the floors.
Height of the ground floor = 24 feet
Height of each floor (except ground floor) = 17 feet
Number of floors (excluding ground floor) = 7 - 1 = 6
Total height of the building = Height of the ground floor + (Height of each floor * Number of floors)
Total height of the building = 24 + (17 * 6)
Total height of the building = 24 + 102
Total height of the building = 126 feet
Therefore, the building is 126 feet tall.

t varies inversely as the square root of u.
t = 3 when u = 4.
Find t when u = 49.
Answer:
t = [tex]\frac{6}{7}[/tex]
Step-by-step explanation:
Given that t varies inversely as the square root of u then the equation relating them is
t = [tex]\frac{k}{\sqrt{u} }[/tex] ← k is the constant of variation
To find k use the condition t = 3 when u = 4, thus
k = t[tex]\sqrt{u}[/tex] = 3 × [tex]\sqrt{4}[/tex] = 3 × 2 = 6
t = [tex]\frac{6}{\sqrt{u} }[/tex] ← equation of variation
When u = 49, then
t = [tex]\frac{6}{\sqrt{49} }[/tex] = [tex]\frac{6}{7}[/tex]
The value of 't' when 'u = 49' in the equation [tex]'t = k/\sqrt(u)[/tex]' is approximately '0.86'. This was calculated using the concept of inverse variation in mathematics.
Explanation:The question is dealing with the concept of inverse variations in math. The given expression states that 't' varies inversely with the square root of 'u'. This can be represented mathematically as [tex]'t = k/\sqrt(u)',[/tex] where 'k' is the constant of variation.
From the problem we know that 't = 3' when 'u = 4'. Substituting these terms in into the equation above, we can solve for 'k'. Doing this yields [tex]'k = 3\times \sqrt(4) = 6.'[/tex]
Now that we have found 'k', we can find the value of 't' when 'u = 49'. We can do this by plugging in the known values into the equation. So [tex]'t = 6/\sqrt(49)'.[/tex] It simplifies to 't = 6/7' or about '0.86'.

7. A baker's dozen (13) of cookies is on sale
for $4.94. What is the cost of an individual
cookie?
ya
Students at a bake sale sell bags of cookies for $2.35 each and bags of miniature muffins for $1.75 each. While selling their baked goods, the students also received a $20 donation. The amount of money the students make from selling c bags of cookies and m bags of muffins can be modeled by the expression 2.35c + 1.75m + 20. Interpret the expression 2.35c + 1.75m in this context.
A
The expression 2.35c + 1.75m represents the money earned from selling c bags of cookies.
B
The expression 2.35c + 1.75m represents the money earned from selling m bags of muffins.
C
The expression 2.35c + 1.75m represents the money earned from selling c bags of cookies and m bags of muffins.
D
The expression 2.35c + 1.75m represents the money earned from selling one bag of cookies and one bag of muffins.
Answer:
Option C (The expression 2.35c + 1.75m represents the money earned from selling c bags of cookies and m bags of muffins).
Step-by-step explanation:
It is given that a bag of cookies is priced at $2.35 and a bag of muffin is priced at $1.75. It is also given that the student sells c bags of cookies and m bags of muffins. The total revenue earned by the student by selling c bag of cookies = $2.35 * c bags = $2.35c and the total revenue earned by the student by selling m bag of muffins = $1.75 * m bags = $1.75m. Therefore, the total revenue earned by the student by selling both cookies and muffins = 2.35c + 1.75m. This expression (2.35c + 1.75m) represents the money earned from selling c bags of cookies and m bags of muffins. Therefore, C is the correct choice!!!

3/4 is greater than 7/10.
Find the least common denominator or LCM of the two denominators:
LCM of 4 and 10 is 20
For the 1st fraction, since 4 × 5 = 20,

Which number is between 21 and 3π 2 ? A π + 1 B 14 3 C 5 D 26
The answer is D, 26. [tex]3\pi^2[/tex] is about 26.6!
Final answer:
The number that is between 21 and 3π/2 is 5.
Explanation:
To find the number that is between 21 and 3π/2, we need to determine the value of 3π/2 first. Since π is approximately 3.14, 3π/2 is approximately (3)(3.14)/2 = 4.71.
Now we can compare this value to 21. Since 4.71 is less than 21, we need to find a number that is greater than 4.71 but less than 21. The only option in the given choices that fits this criteria is Option C, 5.

f(x) is greater.
g(x) is greater.
f(x) and g(x) are the same when x = 3.
g(x) is undefined when x = 3.
Answer:
f(x) is greater
Step-by-step explanation:
The function that has a greater value when x = 3 is: A. f(x) is greater.
What is a linear function?In Mathematics and Geometry, a linear function refers to a type of function whose equation is graphically represented by a straight line on the xy-plane or cartesian coordinate.
Based on the information provided, we can logically deduce the following linear functions;
f(x) = 3x + 1
g(x) = 4x - 5
When x is equal to 3, we have:
f(x) = 3x + 1
f(3) = 3(3) + 1
f(3) = 10
g(x) = 4x - 5
g(3) = 4(3) - 5
g(3) = 7.
Therefore, f(x) is greater.

fritz drew an array with 5 rows of dots . he drew 15 dots altogether. how many dots are in each row of fitz's array ? how do you know ?
There are 3 dots in each row of Fritz's array. This conclusion is reached by dividing the total number of dots (15) by the number of rows (5). This is an exercise in simple division and understanding arrays in mathematics.
Explanation:The subject of this question from Fritz is Mathematics, specifically, it's about arrays and simple division.
To find out how many dots are in each row of Fritz's array, we need to use division. In this case, the total number of dots (15) would be divided by the number of rows (5).
So, we calculate: 15 ÷ 5 = 3.
So, there are 3 dots in each row of Fritz's array. We know this is correct because the definition of an array in mathematics is a collection of objects or numbers arranged in rows, and each row has the same number of items.

On Monday, 449 students went on a trip to the zoo. All 9 buses were filled and 8 students had to travel in cars. How many students were on each bus?
Answer:
Each bus could pick up 49 students
Step-by-step explanation:
(449-8):9=49
Answer:
Number of students on each bus = 49
Step-by-step explanation:
On Monday, 449 students went on a trip to the zoo. All 9 buses were filled and 8 students had to travel in cars.
Total number of students = 449.
Number of students traveled in car = 8
Number of students traveled in bus = 449 - Number of students traveled in car = 8
Number of students traveled in bus = 449 - 8 = 441
Number of buses = 9
Number of students traveled in bus = Number of buses x number of students on each bus
441 = 9 x number of students on each bus
Number of students on each bus = 49
