Answer:

£54

Step-by-step explanation:

According to the ratio:

Bridget = 4/17

Brian = 9/17

Caroline = 4/17

____

So if Bridget and Caroline receive £48, that would mean £48 is 8/17 of the total amount. We can find 1/17 of the money by dividing £48 by 8.

48 / 8 = 6

And then multiply that by 9 to find 9/17 of the money (the amount Brian has).

6 x 9 = 54

Answer:

Area of the shape=241.2cm^2

Perimeter of the shape=76.08cm

Step-by-step explanation:

Find the base for the first triangle = tan(75°)=O/A

= A=30/tan(75°)

=A = 8.04cm (2decimal place)

Area of first triangle= 1/2×Base×height

=1/2×8.04cm×30cm

=120.6cm^2

So total area for the shape is = 2×120.6cm^2

=241.2cm^2

Perimeter of the shape = 2(30cm+8.04cm)

=76.08cm

Answer:

x=5.3

Solving:

6*x, 4*8

these are both 90 degree angles, but what is the solution for x?

8*4=32 solving the area, so we need to get the same thing for the other

32 divided by 6 equals 5.333 repeating

Nearest tenth huh?

5.3

so X=5.3

Answer:

  a.  2/3

Step-by-step explanation:

The bar over the 6 means the digit is repeated indefinitely. A bit of algebra can turn a repeating decimal into a fraction. Let x represent the value of the repeating decimal.

  [tex]x=0.6\overline{6}\\\\10x=6.6\overline{6}\\\\10x-x=6.6\overline{6}-0.6\overline{6}\\\\9x=6\\\\x=\dfrac{6}{9}=\boxed{\dfrac{2}{3}}[/tex]

The attachment shows the long division of 2/3 gives a repeating decimal with a repeating digit of 6. You can tell the quotient repeats when the new dividend (after subtraction) is equal to a dividend you have seen before. In this case, the dividend is repeatedly 20, and the quotient digit is repeatedly 6.

The point of the long division is to show you that 2/3 is the correct answer choice for a rational number equivalent to 0.666...(repeating).

Step-by-step explanation:

she gets $195 per week plus 3% on sale OVER $1000.

ok. so, her weekly sales were $7800.

that means we need to calculate 3% of ... $6800 !

as she gets the commission only on sales that are over $1000.

6800 = 100%

1% = 100%/100 = 6800/100 = 68

3% = 1%×3 = 68×3 = $204

so, she earned $195 + $204 = $399 per week

and as there are 52 weeks per year, she then earned

399×52 = $20,748 per year.

Answer:

x = -4

Step-by-step explanation:

Since we are given that y = -3, we substitute the y for -3

Now we have:

-3 = 2x + 5

Subtract 5 on both sides to leave 2x alone

-8 = 2x

Divide by 2 on both sides to isolate x

The given relationships is that Necklace B is the shortest of the 3

necklaces and Necklace C would be the longest.

Reasons:

The number of necklaces = 3

Sum of the lengths of the necklaces = 445 mm

Length of Necklace A = 45 mm + Length of Necklace B

[tex]\displaystyle Length \ of \ Necklace \ B = \mathbf{\frac{Length \ of \ Necklace \ C}{2}}[/tex]

Required:

The length of Necklace A

Solution:

Let A represent Necklace A, B represent Necklace B, and C represent

Necklace C, we have;

A + B + C = 445

A = B + 45

[tex]\displaystyle B = \frac{C}{2}[/tex]

Therefore;

B = A - 45

2×B = C

2 × (A - 45) = C

Which gives;

A + A - 45 + 2 × (A - 45) = 445

4·A - 135 = 445

[tex]\displaystyle A = \frac{445 + 135}{4} = \mathbf{145}[/tex]

The length of Necklace A = 145 mm

Answer:

ya what to do explain huh

Answer:

x = 3/2y

y = 2/3x

Step-by-step explanation:

x = 3/2y

Swap sides so that all variable terms are on the left hand side

2x + 15 = 3y + 15

Subtract 15 from both sides

2x = 3y + 15 - 15

Subtract 15 from 15 to get 0

2x = 3y

Divide both sides by 2

2x/2= 3y/2

Dividing by 2 undoes the multiplication by 2

X = 3y/2

Y = 2/3x

Subtract 15 from both sides

3y = 2x + 15 - 15

Subtract 15 from 15 to get 0

3y = 2x

Divide both sides by 3

3/3y = 2/3x

Dividing by 3 undoes the multiplication by 3

y = 2/3x

Histograms are used to represent data using bars

The dataset is given as:

3, 6, 5, 9, 12, 14, 18, 4, 13, 12, 4, 3, 11, 14

Rearrange in ascending order

3, 3, 4, 4, 5, 6, 9, 11, 12, 12, 13, 14, 14, 18

Calculate the range

Using 4 classes, the class width is
