Answer:

£1290

Step-by-step explanation:

35%+40%= 75%

£600=25% £600÷20=30 25%of till = 30 notes 100%=120 notes

40% of 120 =48notes 48x10=£480

90notes-48notes=42notes

42x£5=£210

£600+£480+£210=£1290

Answer:

choose option B. - 4

Step-by-step explanation:

Slope intercept form

y - 5 = 3 (x - 3)

y = 3x - 9 + 5

y = 3x - 4

Answer:

x=70

Step-by-step explanation:

First subtract 30 from 180

180-30=150

Subtract 10 from 150

150-10=140

Divide 140 and 2

140÷2=70

Answer:

x=70

Step-by-step explanation:

angles on a straight line add to 180

so first you do 180-30 which equals to 150

this means that 2x+10=150

take away 10 from both sides and your left with

2x=140

since you are finding x

you divide both sides by 2

x=70

Answer:

16f+28

Step-by-step explanation:

just had to simplify the expression

Answer:

16f+28

Step-by-step explanation:

Use the distributive property.

4(4f)+4(7)

16f+28

Answer:

28

Step-by-step explanation:

784 can be divided by two 4 times.

This means that there are two pairs of 2s that can come out the radical.

2*2 = 4.

then now we have 49 left inside and we know that this is 7 squared, meaning that there is a pair of 7 inside the radical.

7 comes out and now we have 7 times 4 which is 28.

Answer:

8

Step-by-step explanation:

add 12+3 is 15, then divide 120 and 15 which is 8

Answer:

8x^3y

Step-by-step explanation:

The area of a rectangle is length * width.

area = 4x^2y * 2x =

= 4 * 2 * x^2 * x * y

area = 8x^3y

Answer:

a) Monica's error was she used the formula = Base × Height

This formula is wrong formula

b) The unit for area of a triangle is square inches not inches

Step-by-step explanation:

Monica has a triangular piece of fabric. The height of the triangle is 15 inches and the triangle's base is 10 inches. Monica says that the area of the fabric is 150 inches. What error did Monica make

The area of a triangle is = 1/2 × Base × Height

From the question

Base = 10 inches

Height = 15 inches

Area of the triangular fabric = 1/2 × 10 × 15

= 75 square inches

a) Monica's error was she used the formula = Base × Height

This formula is wrong formula

b) The unit for area of a triangle is square inches not inches

Answer:  49 square cm

======================================================

For any rectangle, the opposite sides are the same length.

Set the given expressions equal to x and solve to get

2x-1 = x+3

2x-x = 3+1

x = 4

So each opposite side is:

Each side being the same length (7) confirms we have the correct x value.

------------

Let's say L = 7 is the length and W is the unknown width.

We'll use the perimeter of a rectangle formula given below with P = 28 as the given perimeter. Solve for W.

P = 2*(L+W)

28 = 2*(7+W)

28/2 = 7+W

14 = 7+W

7+W = 14

W = 14-7

W = 7

-------------

The rectangle has a length of L = 7 and width of W = 7, so its area is

A = L*W

A = 7*7

A = 49 square cm

Because we have the length and width as the same value, this rectangle is also a square.

Answer:

h = 32

Step-by-step explanation:

In the given figure, for the first parallelogram, base is 36 and height is 24 while for the other parallelogram, base is 27 and height is h.

The area of a parallelogram is given by :

A = base × height

So,

The both parallelograms,

[tex]36\times 24=27h\\\\h=\dfrac{36\times 24}{27}\\\\h=32[/tex]

So, the value of h is 32.

Answer:

A. P=11*3 = 33 ft

   A= 21*3 = 63 ft^3

B. P = 9*3 = 27 ft

   A = 15*3 = 45 ft^3

C. P = 20*3 = 60 ft

   A = 24*3 = 72 ft^3

D. P = 13*3 = 39 ft

   A = 25*3 = 75 ft^3

Answer:

its not 6/3, that's all I know-

Step-by-step explanation:

I put 6/3 down myself and it did not work/I got it wrong.

Answer:

6/20 and 9/30

Step-by-step explanation:

Any fraction that can be simplified to 3/10 by dividing the numerator and the denominator is considered equivalent. If you look at the fractions above 6/20 is literally the same thing as 3/10 but I just multiplied the 3 and 10 times 2. As long as you multiply/divide both the numerator and the denominator by the same number the answer you get should be equivalent.

Answer:

b = (d-c)/a

Step-by-step explanation:
