divide 210 between James and John in ratio 3:4
well, we can simply divide 210 by (3 + 4) and then distribute accordingly
[tex]\stackrel{James}{3}~~ : ~~\stackrel{John}{4} ~~ \implies ~~ \stackrel{James}{3 ~~ \cdot \frac{210}{3+4}}~~ : ~~\stackrel{John}{4~~ \cdot \frac{210}{3+4}} ~~ \implies ~~ \stackrel{James}{3 \cdot \frac{210}{7}}~~ : ~~\stackrel{John}{4 \cdot \frac{210}{7}} \\\\\\ \stackrel{James}{3(30)}~~ : ~~\stackrel{John}{4(30)} ~~ \implies ~~ \stackrel{James}{90}~~ : ~~\stackrel{John}{120}[/tex]
Answer:
James- 90 and John- 120
Step-by-step explanation:
Since you want to divide 210 with a ratio of 3:4. It's easiest to first add your 3 and 4. This =7. Now you know you have to divide 210 by 7 before you give them to James and John. 210 divided by 7 = 30. Now do 30 times each ratio.
James has 30 x 3 and John has 30 x 4
this leaves you with 90 and 120
The length of a rectangle is 4 inches more than its width. The area of the rectangle is equal to 4 inches less than 4 times the perimeter. Find l and w
Answer:
Step-by-step explanation:
[tex]l=w+4[/tex]
[tex]A=l*w\\l=w+4\\A=(w+4)w\\A=w^2+4w[/tex]
[tex]P=2l+2w\\A=4p-4\\A=4(2l+2w)-4\\A=8l+8w-4\\l=w+4\\A=8(w+4)+8w-4\\A=8w+32+8w-4\\A=16w+28[/tex]
[tex]16w+28=A=w^2+4w\\16w+28=w^2+4w\\w^2-12w-28=0\\w^2-14w+2w-28=0\\(w^2-14w)+(2w-28)=0\\w(w-14)+2(w-14)=0\\w+2=0=w-14\\w=-2and14[/tex]
Since w represents a measurement of a physical object in inches, it cannot be negative. So, [tex]w\neq-2[/tex]. The width of the rectangle is 14 inches.
The length is given as 4 inches more than the width, so the length is 18 inches.
This satisfies all the requirements of the question:
[tex]4P-4=A\\P=2(18)+2(14)=64in\\4P=64in(4)=256in\\A=18in*14in=252in^2\\256-4=252\\252=252[/tex]

Absolute FunctionAn absolute value function is a function in algebra where the variable is inside the absolute value bars. This function is also known as the modulus function and the most commonly used form of the absolute value function is f(x) = |x|, where x is a real number. Generally, we can represent the absolute value function as, f(x) = a |x - h| + k, where a represents how far the graph stretches vertically, h represents the horizontal shift and k represents the vertical shift from the graph of f(x) = |x|. If the value of 'a' is negative, the graph opens downwards and if it is positive, the graph opens upwards.
In the questions given;
1) |3x - 1| - |2x + 5 - (5 - x)| = 0
x = 1/6
2) |2(x + 1) - 4| - 4| = |2 - 2(2 - x)|
x = 1

While running against the walkway, she can cover 24 feet in 2 seconds. Find Hannah's rate (in feet per second) if the walkway stopped moving.
The present age of Melody is 9 and her sister is 24 .
the two digit number is 39
How to find the ages of a person ?
Consider the difference between the individual's birthdate and the present day: days = current day - birth date. Age = (years 365) + (months 31) + days should be replaced with these variations. The individual's age is expressed in days. To get the age in years, divide the outcome by 365.
Let present age of melody be y and her sister age be x
Four years ago age of Melody be (y - 4) and her sister age be (x - 4)
After six years age of Melody be (y + 6) and her sister age be (x + 6)
∴ [tex]\frac{(x-4)}{4} = (y - 4)[/tex]
[tex]\frac{(x+6)}{2} = (y + 6)[/tex]
The equation becomes
x + 6 = 2y + 12
x = 2y +6 ⇒ (1)
x - 4 = 4y -16
x = 4y - 12 ⇒(2)
Solving (1) and (2)
x - 2y = 6
x - 4y = -12
2y = 18
y = 9
Substituting the value of y in eq(1)
x = 2*9 + 6
x = 18 +6
x = 24
Let xy be the two digit number.
10x + y
The value of this number is 6 less (-6) than five times the unit digit (5y). So:
10x + y = 5y - 6
The sum of the digits of the 2-digit number is 12:
x + y = 12
So y = 12 - x
Substitute 12-x for y:
10x + y = 5y - 6
10x + 12 - x = 5(12-x) - 6 [Substituted 12-x in place of y]
9x + 12 = 60 - 5x - 6
14x = 42
x = 3
y = 12 - x
= 12 - 3

The remainder is what’s left when you divide. The part you cannot divide.
You can divide 75 by 3 = 25, so the remainder is 1.
The correct dividend of 76 is required to yeild a quotient of 25 and a remainder of 1 when divided by 3.
Division FormulaWe can know the dividend, the quotient and the remainder of the division using the division formula: (Divisor x Quotient) + Remainder = Dividend
Divisor = 3
Quotient = 25
Remainder = 1
(3 × 25) + 1 = 75 + 1
(3 × 25) + 1 = 76
Thus, the dividend 76 divided by the divisor 3 have the quotient 25 and a remainder when of 1.

Girard buys 9 tons of rocks to build a long rock wall. Each section
of the wall weighs 500 pounds, or ¼
ton. How many sections can
Girard build?
Answer: 36
Step-by-step explanation:
4 sections are 2,000 lbs or 1 ton
To find the pounds Girard has to build, we know we have 9 tons, therefore if each ton is 2,000 lbs, multiply 2,000 by 9 to get 18,000 lbs to use
2,000 lbs per ton x 9 tons= 18,000 lbs to use
now take the 18,000lbs and divide by 500 to find the number of sections we can build
18,000lbs / 500 pounds per section = 36
36 sections is the answer

3. What is the proper ordering
(from greatest to least) of the
following numbers?
I.58/67
II. 0.58%
III. 58%
IV. 5.8%
O I, III, II, IV
III, IV, II, I
I, III, IV, II
IV. I. III. II
The proper order from greatest to least is option (C) I, III, IV and II
Convert each term to the decimal form
The first terms is 58/ 67
58 / 67 = 0.87
The second term is 0.58%
Convert the percentage to simple fraction
0.58% = 0.58 / 100
= 0.0058
The third term is 58%
Convert the percentage to simple fraction
58% = 58/100
= 0.58
The fourth term is 5.8%
Convert the percentage to simple fraction
5.8% = 5.8/100
= 0.058
The order from greatest to least is
0.87 > 0.58 > 0.058 > 0.0058
Hence, the proper order from greatest to least is option (C) I, III, IV and II

Does the equation describe a function? y=8
The equation y = 8 does not describe a function
How to determine if an equation describes a function?
A function is an equation that has only one output or answer (y) for every input (x) e.g y = 2x
If we plot y =8 on a coordinate plane, you would see that at the point of (0, 8) is a horizontal line.
Also, no matter the value of the input (x), the value of when of the output (y) will always remain 8. This does not fit the description of a function
Therefore, the equation y =8 does not describe a function
