Answers
Answer:
18 : 30
Step-by-step explanation:
3 + 5 = 8 (Total units)
48 ÷ 8 = 6
3 units = 6 x 3 = 18
5 units = 6 x 5 = 30

18:30I HOPE IT HELPS ❤❤A town has accumulated 2 inches of snow, and the snow depth is increasing by 6 inches every hour. A nearby town has accumulated 7 inches, and the depth is increasing by 3 inches every hour. In about how many hours will the snowfall of the towns be equal?
Answers
Let x equal the number of hours where the snowfall will be equal in both towns.
In town one, the amount of snowfall can be written as 2+6x. In town two, the amount of snowfall can be written as 7+3x.
So to find when they will be equal, set them equal and solve:
2+6x=7+3x
3x=5
x=5/3 or 1 2/3 hours. In minutes, this is 100 minutes.

Answers
Answer:
A: [tex]\frac{1}{2\sqrt{x-1} }[/tex]
B:[tex]\frac{1}{4\sqrt[4]{x^{3} } }[/tex]
c: 2x
Step-by-step explanation:
To find the derivative of x raised to the nth power we use the following template
[tex]x^{n}=nx^{n-1}[/tex]
Something else to keep in mind is that
[tex]\sqrt[n]{x^{y}}=x^{y/n}[/tex]
So knowing this we can rewrite a as follows
[tex]\sqrt{x-1} =(x-1)^{1/2}[/tex]
so we can use the template above and get
[tex]\frac{1}{2}(x-1)^{.5-1}[/tex]
So that simplifies to
[tex]\frac{1}{2}*(x-1)^{-\frac{1}{2}[/tex]
[tex]\frac{(x-1)^{-.5}}{2}[/tex]
[tex]\frac{1}{2\sqrt{x-1} }[/tex]
B: Same kind of deal here
[tex]\sqrt[4]{x}=x^{\frac{1}{4} }[/tex]
[tex]\frac{1}{4} *x^{\frac{1}{4}-1}[/tex]
[tex]\frac{x^{-\frac{3}{4}}}{4} =\frac{1}{4\sqrt[4]{x^{3} } }[/tex]
C: this one is by far the easiest because the derivative of a constant is 0 so we can just apply the same template from before and get
2x

What is division?Division is a mathematical operation, in which we distribute the number in equal parts, the number on the upper side is the total quantity and the number on the bottom side is equal parts of numbers which have to be distributed.
We denote division by '÷' this symbol.
Given that,
Freddie made the number line to model the laps he walks around a track at his school,
And each lap is 0.25 miles,
And Freddie walks a total of 1 mile,
So to find the number of laps he walks,
we can divide the total distance by the distance per lap:
Number of laps = 1/0.25 mile/miles per lap
= 4 laps
Hence, the number of laps is 4

a = 11
Step-by-step explanation:
Given the equation 2/3a - 7 = 1/3
We are to find the value of a that satisfies the equation
2/3 a = 1/3 + 7
2/3 a = (1+21)/3
2/3 a = 22/3
2a = 22
a = 22/2
a = 11

Answers
Answer: 50 feet
Step-by-step explanation:
Let the length be represented by x
The width of the basement is 4/5 its length. Therefore, the width is 4/5x = 0.8x
Area = Length × Breadth
2000 = x × 0.8x
0.8x² = 2000
x² = 2000/0.8
x = ✓2500
x = 50
Therefore, the length is 50feet

Solve the simultaneous equations
8x + 3y = 45
2x + 3y = 27
Answers
8x + 3y = 45 * -2
2x + 3y = 27 * 8
-16x - 6y = 90
16x + 24y = 216
24y = 216
y = 216/24
y = 9
8x + 3y = 45
8x + 3(9) = 45
8x + 27 = 45
8x = 45 - 27
8x = 18
x = 18/8
x = 2.25
x = 3 and y = 7 are the answers to the simultaneous equations 8x + 3y = 45 and 2x + 3y = 27.
What are linear equations?A linear equation is an equation that describes a straight line on a coordinate plane. It is an equation of the form y = mx + b, where x and y are variables, m is the slope of the line, and b is the y-intercept (the point where the line intersects the y-axis).
To solve the simultaneous equations:
8x + 3y = 45 ...(1)
2x + 3y = 27 ...(2)
By adding or removing equations, we can utilise the procedure of elimination to get rid of one of the variables. In this situation, y can be removed by deducting equation (2) from equation (1) as shown below:
(8x + 3y) - (2x + 3y) = 45 - 27
6x = 18
x = 3
In order to obtain the value of y, we can now change the value of x in either equation (1) or (2). Consider using equation (1):
8x + 3y = 45
8(3) + 3y = 45
24 + 3y = 45
3y = 45 - 24
3y = 21
y = 7
Therefore, the solution to the simultaneous equations 8x + 3y = 45 and 2x + 3y = 27 is x = 3 and y = 7.
