Cheddar cheese costs £7.50 for 1kg
Marie buys 200g of cheese
How much does she pay

Answer: the answer is 40 units squared

Step-by-step explanation:

the SA with a rectangular and square base is 2*s²+4*s*h

2*s²= the surface area

4*s*h= sideways (lateral)

s= 2 and h=4

so then plug it into "2*s²+4*s*h" and you get 2*2²+4*2*4

2*2²+4*2*4

2(4)+32

40

The midpoint of the segment is approximately (3, 2.5).

What is a midpoint of a line segment?

The midpoint of a line segment is given as,

x = (a + c)/2

y = (b + d) / 2

Where (x, y) is the midpoint and (a, b) and (c, d) are the two endpoints.

We have,

To find the midpoint of the segment between two points, we take the average of their x-coordinates and the average of their y-coordinates.

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

where (x1, y1) = (-1, 2) and (x2, y2) = (7, 3)

Midpoint

= ((-1 + 7)/2, (2 + 3)/2)

= (6/2, 5/2)

= (3, 2.5)

Therefore,

The midpoint of the segment is approximately (3, 2.5).

Answer:

Step-by-step explanation:

First, these are points in a plane, hence should be (-1,2) and (7,3)

Then we'll have

-1+7=6/2=3

2+3=5/2=2.5

Then midpoint is (3,2.5)

Answer:

x=-1,y=7

x=-3,y=3

Step-by-step explanation:

y=2x+9

5x^2+(2x+9)^2=54

0=(3x+9)(3x+3)

Answer:

1/36

Step-by-step explanation:

The only way to get a sum of 2 with two dice is to roll 1s on both. there is one 1 on each dice, so you have a 1/6th chance for each. that gives you

1/6 × 1/6

which solves for your answer of
