[tex]\text{Suppose the width of the rectangle is }x\text{ cm}[/tex]
[tex]\text{then the perimeter can be expressed as}[/tex]
[tex]2(24+x)=72[/tex]
[tex]24+x=36[/tex]
[tex]x=12[/tex]
[tex]\text{Therefore the area of the rectangle is }24\cdot x=24\cdot 12=288\text{ cm}{}^2[/tex]
Answer: Solution,
length (l) = 24 cm
perimeter (p)= 74 cm
Area (A) = ?
we know,
P = 2(l + b )
74 = 2( 24 + b)
74 = 48 + 2b
2b = 74 - 48
2b = 26
b= [tex]\frac{26}{2}[/tex]
b = 13
now,
A = l*b
= 24 * 13
= 312 cm square
Therefore, the area of the rectangle is 312 cm square.

Answer:
[tex]\frac{a^{5}b }{x^{6} }[/tex]
Step-by-step explanation:
you just need to forget about 0 because whole equation is raised to 0
and anything raise to 0 is 1
so
[tex]\frac{a^{5}b^{4} }{x^{6}b^{3} }[/tex] law of exponent [tex]a^{n}[/tex] ÷ [tex]a^{m}[/tex] = [tex]a^{n-m}[/tex]
here [tex]b^{4}[/tex] ÷ [tex]b^{3}[/tex] = [tex]b^{4-3}[/tex]
= [tex]b^{1}[/tex]
so the answer will be
[tex]\frac{a^{5}b }{x^{6} }[/tex]

determine the equation of a vertical line that passes through (9,-7)
Answer:
x = 9
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (9, - 7) with x- coordinate 9 , then
x = 9 ← equation of vertical line

Answer: The equations aren't written properly. They seem to be missing something, but if I interpret what is there, we have 1) V = x + 3, and 2) x = -2.
That can't be correct, but if it is, x = -2. and V = 1

The set of ordered pairs (-1, 8), (0, 3), (1.-2), and (2, -7) represent a function. What is the range of the function?
O {x: x = -1, 0, 1, 2}
O {y: y = -7, -2, 3, 8}
O {x: x = -7, -2,-1, 0, 1, 2, 3, 8}
O {y: y = -7, -2, -1, 0, 1, 2, 3, 8}
Intro
Done
The range of the function is: (b) {y: y = -7, -2, 3, 8}
The ordered pairs are given as:
(x,y) = {(-1, 8), (0, 3), (1.-2), and (2, -7)}
The range is the set of output values of the function
The y values represent the range.
So, we have:
y = {8, 3,-2, -7}
Hence, the range of the function is:
{y: y = -7, -2, 3, 8}

Note:if you need to ask any question please let me know.which number does NOT represent an integer? A. 3 B. 20.1 C. -10 D. 20/4
Answer:
the number doesnt represent an integer?
A. 3
B. 20.1
C. -10
D. 20/4
Step-by-step explanation:
We call integers the “counting numbers, their negatives and zero”. I.e. 0,1,−1,2,−2,3,−3,.. etc.
non-integers means “everything except integers”. Which is not well-defined (i.e. nonsense). Why? Because nobody said what “everything” is.
Therefore, when somebody says “non-integer” he has to specify how he defines “everything”. In this case, our “everything” is probably “real numbers”.
Real numbers have an interesting definition concerning an abstract mathematical object called “field” . Let’s forget about that and let’s focus on a high school definition: Real numbers are probably all the numbers you know. They are those represented by a decimal and their negatives e.g. 345.232… and −243.13242240… where there are “infinitely many” digits at the end. Note that 2.5 is also a real number. Integers are too. Basically, real numbers are the numbers used to measure distances and their negatives.
To summirize, your answer is the following:
“non integers” means everything except the integers, where everything is defined however we want. The most common definition of everything in this case is “real numbers” and therefore the most common interpretation of “non integers” is “reals which are not integers”.
Examples of “reals which are not integers”: 1.5,2.88,1.3333… etc
the answer is
B. 20.1

The sun is 1.5 x 10^11 m from earth.
Express this distance with an SI prefix.
Answer:
First, we write the SI prefixed. The SI unit for distance is meters.
Kilo = 10³
Mega = 10⁶
Giga = 10⁹
Terra = 10¹²
Because our value has ten to the power of 11, we will use the closest and lowest power prefix, which is giga.
1.5 x 10¹¹ / 10⁹
= 1.5 x 10² Gm or 150 Gm
Writing in kilometers, we simply repeat the procedure except we divide by 10³ this time.
1.5 x 10¹¹ / 10³
= 1.5 x 10⁸ km
Step-by-step explanation:
First, we write the SI prefixed.
The SI unit for distance is meters.
Kilo = 10³
Mega = 10⁶
Giga = 10⁹
Terra = 10¹²
Because our value has ten to the power of 11, we will use the closest and lowest power prefix, which is giga.
1.5 x 10¹¹ / 10⁹
= 1.5 x 10² Gm or 150 Gm
Little more explanation : In scientific notation, if the exponent of 10 is positive, the number is very very large. In the metric system, very large numbers are expressed in megameters (Mm) or gigameters (Gm). Gigameters is equal to 10⁹ meters. So, in SI prefix, that would be equal to 150 Gm. In kilometers, that would be equal to:
1.5×10¹¹ m * (1 km/1000 m) = 1.5×10⁸ km

Evaluate the function rule for the given value. y = 12 • 3^x for x = –2
A. 4/9
B. 4/3
C. –72
D. 4
Answer:
B
Step-by-step explanation:
Using the rule of exponents
[tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]
Given
y = 12 × [tex]3^{x}[/tex] ← substitute x = - 2 into the expression
y = 12 × [tex]3^{-2}[/tex] = 12 × [tex]\frac{1}{3^{2} }[/tex] = 12 × [tex]\frac{1}{9}[/tex] = [tex]\frac{12}{9}[/tex] = [tex]\frac{4}{3}[/tex] → B
Answer:
B
Step-by-step explanation:
y= 12 *3 ^x , substitute x with -2
y=12 *3^-2 , use the rule a^ - b = 1 /a^b
y= 12 / 3^2 , 3^2 =3*3 = 9
y= 12/9, divide both numbers by 3, 12÷3/ 9÷3
y= 4/3
A crew of 2 skilled workers and 4 helpers is to perform construction work that requires a quantity of 1,250 units. Base wages for a skilled worker and a helper are $50/hr and $25/hr, respectively. The crew’s production rate is known to be 25 units/hr under normal working conditions (8 hours/day). Calculate the total hours that the crew to complete the work and the total direct labor cost to complete the work.
The total hours needed for the crew to complete the job is 50 hours and the total direct labour cost is $3750
In order to calculate the total hours that it would take to complete the work, divide the total units needed to complete the construction work by the crew's production rate
Total hours it would take to complete the work = total units needed to complete the job / crew’s production rate
1250 units / 25 units/hr = 50 hours
Total direct labor cost = total skilled labor wages + total wages for the helps
Total skilled labor wages = base wages for a skilled worker per hour x total hours needed to complete the work
$50/hr x 50 hours = $2500
total wages for the helps = base wages for the helps per hour x total hours needed to complete the work
$25/hr x 50 hours = $1250
Total direct labour cost = $2500 + $1250 = $3750
