To solve for the area of rectangle, you use this formula A = length × width. But we're doing it reversal, we will divide the width to the area
[tex]\large\tt{A \: = \: l \: \times \: w}[/tex][tex]\large\tt{48cm^{2} \: = \: l \: \times \: 6cm}[/tex][tex]\large\tt{48cm^{2} \: \div \: 6cm \: = \: l}[/tex][tex]\large\tt{48cm^{2} \: \div \: 6cm \: = \: \pmb{8cm}}[/tex]Therefore, The length is 8cm.
================================
Hey ! there
Answer:
Length of rectangle is 8 cm .Step-by-step explanation:
In this question we are provided with a rectangle having area 48 cm² and width 6 cm . We are asked to find the length of rectangle .
We know that ,
[tex] \qquad \qquad\underline{\boxed{\frak{Area_{(Rectangle)} = l \times w}}}[/tex]
Where ,
l refers to Lengthw refers to WidthSOLUTION : -
We are finding value of length by substituting value of width as 6 cm and area as 48 cm² in the formula . So ,
[tex] \quad\longmapsto \qquad \:48 = 6 \times l[/tex]
or ,
[tex] \quad\longmapsto \qquad \:48 = 6l[/tex]
Dividing with 6 on both sides :
[tex] \quad\longmapsto \qquad \: \cancel{\dfrac{48}{6}} = \dfrac{ \cancel{6}l}{ \cancel{6}} [/tex]
We get ,
[tex] \quad\longmapsto \qquad \: \orange{\underline{\boxed{ \frak{l = 8 \: cm}}}} \quad \bigstar[/tex]
Henceforth , Length of rectangle having area 48 cm² and width 6 cm is ❝ 8 cm ❞Verifying : -
We are verifying our answer by substituting value of length and width in formula and equating it with given area . So ,
[tex] 8 \times 6 = 48[/tex][tex]48 = 48[/tex][tex] \rm{L.H.S = R.H.S}[/tex][tex] \rm{Hence , \: Verified .}[/tex]Therefore , our answer is correct .

Charles has 24 marbles. He has 6 more marbles than blue marbles. Which equation represents this situation.
LOOK AT THE PICTURE BELOW!
Answer:
n + (n + 6) = 24.
Step-by-step explanation:
Let him have n blue marbles, then he has n + 6 other narbles.
He has a total of 24 marbles, so:
n + (n + 6) = 24.
Answer:
B) n + (n + 6) = 24, where n is the blue marbles

The vector u has magnitude 6 and direction 330°. If vector v = =-u, then what is
the magnitude and direction of vector v? Write your direction in degrees in the
interval 0° 0 < 360°.
Here we go ~
It's been given that :
[tex]\qquad \sf \dashrightarrow \: \vec{v} = - \vec{u}[/tex]
And magnitude of vector u is 6 units and with a direction 330°
And we are asked to find the magnitude and direction of vector v ~
So, let's get stated ~
As we can observe, vector v and vector u have equal magnitude because they have equal sign between them.
that is :
[tex]\qquad \sf \dashrightarrow \: | \vec{v} | = | \vec{u}| [/tex]
[tex]\qquad \sf \dashrightarrow \: | \vec{v}| = 6 \: units[/tex]
And the negative sign in the equation shows that the two vector have opposite directions or you can say they are anti-paralllel.
So, we can just rotate vector u by 180° to get vector v ~
[tex]\qquad \sf \dashrightarrow \: \hat{n} = 330 \degree - 180 \degree[/tex]
[tex]\qquad \sf \dashrightarrow \: \hat{n} = 150 \degree[/tex]
Conclusion :
vector v has magnitude of 6 units and direction 150°Tegan is checking her tax bill for the last year.
the tax rates were as follows:
•No tax on the first of £11,000 earnings
•earnings in excess of £11,000 and up to £43,000 taxed at a rate of 20%
•earnings in excess of £43,000 and up to £150,000 taxed at a rate of 40%
last year Tegan earned £48300 before tax
how much tax did she pay in total. please help give you brainiest.
A percentage is a way to describe a part of a whole. The total tax of Tegan's earnings will be £8,520(£6,400+£1,200).
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Since there is no tax for the first £11,000, therefore, the earnings which will be taxed,
£48,300 - £11,000 = £37,300
The amount of tax for the income of £11,000 to £43,000, will be,
20% of (£11,000 to £43,000)
= 20% × (£43,000 - £11,000)
= £6,400
The amount of tax for the income of £11,000 to £150,000, will be,
40% of (£43,000 to £48,300)
= 40% × (£5,300)
= £2,120
Hence, the total tax of Tegan's earnings will be £8,520(£6,400+£1,200).

Paula has a client who wants to invest into an account that earns 4% interest, compounded annually. The client opens the account with an initial deposit of $4,000, and deposits an additional $4,000 into the account each year thereafter.
Assuming no withdrawals or other deposits are made and that the interest rate is fixed, the balance of the account (rounded to the nearest dollar) after the eighth deposit is __________.
The balance of the account after the eighth deposit will be $36857 if an account that earns 4% interest, compounded annually.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
P = 4000, r = 4% = 0.04 and an additional $4,000 into the account each year thereafter.
The balance of the account after the eighth deposit;
[tex]A = \rm 4000\times \dfrac{1\times (1+0.04)^8}{1-(1+0.04)}[/tex]
A = 36856.90 ≈ $36857
Thus, the balance of the account after the eighth deposit will be $36857 if an account that earns 4% interest, compounded annually.

BC = 5.87
Step-by-step explanation:
To find the last angle:
180° - 50° - 90° = 40°
Once we know that, we can use our given side angle pair to figure out the length.
[tex]\frac{7}{sin(50)}[/tex] * [tex]\frac{?}{sin(40)}[/tex] -> [tex]\frac{7*sin(40)}{sin(50)}[/tex]= ?
Then we plug into a calculator to get: 5.87
Answer:
5.87
Step-by-step explanation:
Concepts
The three different trigonometric functions are sine, cosine, and tangent. They can be memorized as the mnemonic SOHCAHTOA, where:
Sine = Opposite/HypotenuseCosine = Adjacent/HypotenuseTangent = Opposite/AdjacentThe hypotenuse will always stay the same, but depending on the highlighted angle, the opposite and adjacent side can change.
Application
In this case, we're asked to find the length of BC. We're given the length of the opposite side as 7 units. The adjacent side to m∠50° is BC. Since we're dealing with opposite and adjacent, we're going to be using tangent.
Solution (Calculator Needed)
tan(50°) = 7/xtan(50°) * x = 7/x * xtan(50°)x = 7x = 7/tan(50°)x ≈ 5.871/4 how do u get 16 from it show me the calculations

Angle measures in polygons need ASAP thank you
Answer:
1) 25
2) 61
3) 20
4) 25
5) 65.46
Explanation:
1) Use the formula " (n-2)180. N = the number of sides.
(25-2)180 = 4140
2) The sum of the polygon is 900.
(7-2)180 = 900
Add up all the numbers and variables then equal them to 900.
3) To find an interior of an 18-gon is the use of this formula:
(n-2)180 = Sum of the polygon
Sum / n
(18-2)180 = 2880
2880 / 18 = 160
180 - 160 = 20 ; Because they are supplementary.
4) (25-2)180 = 4140
4140 / 25 = 165.6
5) Copy the formula for explanation #3. But instead of an 18-gon, do 11-gon.
Mr Thando received a statement of water usage from BCM. According to the statement he has to pay a sum of R281,27incl VAT for March consumption.

It can be estimated that the total amount of water that Mr. Thando used is 40 Kiloliters. See the arithmetic calculation/ explanation below and the reconstructed table attached.
What is the calculation of Mr. Thando's Water Usage?The approximate amount of water that he has been charged for will be given as follows:
The maximum fee for Band A + Maximum fee for Band B + Maximum fee for Band C.
Which is: (0) + (6.36 *14) + (7.98*20) = R248.64
Recall that the total amount he was charged is R281.27.
Hence, because the question does not include the percentage of VAT payable, and the referenced table is unavailable, we are forced to assume that the difference between the amount paid and our calculations above is the VAT.
This figure (that VAT) is: R281.27 - R248.64 = R32.63
Hence, the total amount of water used by Mr. Thando is: 6 + 14 + 20 = 40Kl
