Four people have measured the height of a wall using different methods. Their results are shown in the table. Order their measurements from least to greatest.

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:

[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]

The proportion is solved and the number of games won by Ollie and Noelle over the weekend are 10 and 25 respectively

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

Ollie won 2 games for every 5 games that Noelle won

So , the proportion is 2 : 5

Now , when Noelle won 10 games , Ollie won 4 games

And , when Noelle won 15 games , Ollie won 6 games

when Noelle won 20 games , Ollie won 8 games

when Noelle won 25 games , Ollie won 10 games

So , the difference of their winnings is now = 15 games

Hence , the number of games won by Ollie and Noelle over the weekend are 10 and 25 respectively

Step-by-step explanation:

Step-by-step explanation:

the answer for the question is b) 1/4

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

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

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 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}

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

[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.
