Step-by-step explanation:
42 people per minute
how many minutes for 15000 people ?
well, how often does 42 fit into 15000 ?
15000/42 = 357.1428571... minutes
and since we want to bring in everyone of the 15000, we have to count the fraction of the last minute as minute.
so, we have 358 minutes.
and that is in hours, as 1 hour = 60 minutes
358/60 = 5.9... hours
so, the rounded answer is 6 hours.
I will give you BRAINLYEST if you answer this. (I did not get an answer the first time that I asked this)
What is the sign of the product (3) × (−25) × (7) × (−24)?
Positive, because the products (3) × (−25) and (7) × (−24) are negative and the product of two negative numbers is positive

Cómo hallar el alcance de una función cúbica?
Answer:
Cómo hallar el alcance de una función cúbica? or How to find the scope of a cubic function?
Step-by-step explanation:
To find the scope of a cubic function, we first need to understand what the term "scope" refers to. In mathematics, the scope of a function refers to the range or set of all possible values that the function can take.
For a cubic function, which is a polynomial of degree three, the scope can vary depending on its coefficient values. Generally, a cubic function will have an infinite scope which means it can take on any real value. This is because the degree of the polynomial is odd and therefore the function's graph will extend to both positive and negative infinity.
However, if there are additional conditions or constraints given for the cubic function, such as restricted coefficients or a limited domain, then the scope may be constrained accordingly. It is important to analyze the specific details of the cubic function in order to determine any limitations on its scope within a defined range.

Tap X can fill a bath in 12 minutes.
Tap Y can fill a bath in 6 minutes.
How long will it take to fill the bath with both taps running at the same time?
============================================================
Explanation:
Let's say that this tub is 72 gallons. I picked this number since 12*6 = 72. You can pick any number you want, but I picked this number so we end up with whole number results as shown below.
Tap X can fill the 72 gallon tub in 12 minutes. Its rate is 72/12 = 6 gallons per minute. Tap Y has a rate of 12 gallons per minute because 72/6 = 12.
Add the two unit rates: 6+12 = 18
If the two taps are opened at the same time, then they will work at a rate of 18 gallons per minute.
Let x be the number of minutes. The expression 18x represents how much of the tub is full after x minutes. Set this equal to the 72 we started with earlier and solve for x.
18x = 72
x = 72/18
x = 4
It will take 4 minutes if both taps are running at the same time.

Solve by elimination, ordered pair also
4x + 6y = 12

Solving by Eliminating method:
[tex]\sf \leadsto 4x + 6y = 12\:\:- - - (i)[/tex]
[tex]\sf \leadsto 6x+9y = 12 \:\: - - -(ii)[/tex]
Step 1: Multiply Eqⁿ (I) by 3 and Eqⁿ (ii) by 2 to make the coefficients of y equal. Then we get the equations.

[tex]\sf \leadsto 12x + 18y = 24\:\:- - - (iv)[/tex]
Step 2: Subtract Eqⁿ (iii) from Eqⁿ (iv) , we get
[tex]\sf \leadsto (12x + 18y)-(12x + 18y) = 36-24[/tex]
[tex]\sf \leadsto 0 =12, Which is a false statement. [/tex]
Therefore, the pair of equations has no solution.

Lena can knit 14 square inches of a blanket in 3 1/2 hours.
Find the number of square inches knit per hour and the number of hours spent knitting per square inch
Step-by-step explanation:
No. of square inches of knit per hour is 14 and No. of hours spent in knitting 1 square inch is \frac{1}{14}141
Step-by-step explanation:
We are given that Lena can knit 14 square inches of a blanket in hours
So, No. of square inches of knit per hour = 14
No. of hours spent in knitting 14 square inch = 1
No. of hours spent in knitting 1 square inch = \frac{1}{14}141
So, No. of square inches of knit per hour is 14 and No. of hours spent in knitting 1 square inch is \frac{1}{14}141

The thermostat for a house is set to 70°F, but the actual temperature may vary by as much as 4°F. Use an
absolute value inequality to find the range of possible temperatures in the house.
The range of possible temperatures in the house (in degrees Fahrenheit)
Answer:
Step-by-step explanation:
74’F
Answer:
The range of possible temperatures in the house (in degrees Fahrenheit) is 60° F ≤ T ≤ 74°F
Step-by-step explanation:
To Find:
The range of possible temperatures in the house
Solution:
Given:
Thermostat is set to 70 °
Also actual temperature may by a much of 4°
If the temperature is 4°F lower, and actual temperature = 70°- 4° = 66° F
If the temperature is 4°F higher, actual temperature = 70°+4° = 74°
Therefore, The range of possible temperatures in the house (in degrees Fahrenheit) is 60° F ≤ T ≤ 74°F

What is the value of 7m−3n when m = 3 and n = 2?
A: 5
B: 15
C: 24
D: 36
Answer:
B: 15
Step-by-step explanation:
To answer this question, simply plug in the values according to each variable. So, because m = 3, plug the m next to 7 with 3, so then that means that 7 is now multiplied by 3. Then, plug in 2 into n because n = 2, so 3 is being multiplied to n. This is what we get:
7(3) - 3(2)
Now, multiply!
21 - 6
Finally, solve:
21 - 6 = 15
Therefore, the answer is:
B: 15

Ben can paint 280 square feet in 12 minutes. How many square feet can he paint in 1 hour?
Answer:
1400 sq. ft
Step-by-step explanation:
60 min = 1 hour
280 sq. ft / 12 min = x / 60 min
x = 60 min * (280 sq. ft / 12 min)
minuets cancel out
x = 1400 sq. ft

write the rational expressions as equivalent rational expressions with the lowest common denominator
1. The equivalent rational expression with the lowest common denominator of [tex]\frac{2}{3d^{2} + 14d^{2} - 5 }[/tex] is [tex]\frac{2}{(d+5)(3d-1)}[/tex]
2. The equivalent rational expression with the lowest common denominator of [tex]\frac{3d}{3d^{2} - 22d + 7}[/tex] is [tex]\frac{3d}{(d-7)(3d-1)}[/tex]
1.
[tex]\frac{2}{3d^{2} + 14d^{2} - 5 }[/tex]
Let factorise the denominator below
3d² + 14d - 5
-15 and 14
Two numbers we can multiply to get -15 and add to get 14 are 15 and -1.
Therefore,
3d²- d + 15d - 5
d(3d - 1) + 5(3d - 1)
(d+5)(3d-1)
Therefore, the equivalent rational expression with the lowest common denominator will be
[tex]\frac{2}{(d+5)(3d-1)}[/tex]
2.
[tex]\frac{3d}{3d^{2} - 22d + 7}[/tex]
Factorise the denominator
3d²- 22d+7
3d²- d - 21d + 7
d(3d - 1) - 7(3d - 1)
(d - 7)(3d - 1)
Therefore, the equivalent rational expression with the lowest common denominator will be
[tex]\frac{3d}{(d-7)(3d-1)}[/tex]
