Answer:

m Is 30

Step-by-step explanation:

m is 30

because....the sum of angles in a triangle is 180

75+75+m =180

150+m=180

make m the subject of the formula

m=180-150

m=30

Answer:

A) 30°

Step-by-step explanation:

All triangles angles add always to 180°, so we have two already 75° + 75° = 150° thus the angle is 30°

Who packed all the pies? Kane’s bakery makes four flavour pies. The weight of each flavour pie is follows:

svet-max [94.6K]

This is an identical problem answered by myself a few days ago. The answer is reproduced below for your convenience.

It is a very difficult problem if the box sizes are smaller or if there are more pies to pack.
For this particular problem, we first calculate the total weight of pies:
4 apple pies at 700 g = 2800 g
8 banoffee pies at 725 g =5800 g
3 custaard pies at 600 g = 1800 g
5 rhubarb pies at 675 g = 3375 g
for a total of 13775 g

The minimum number of boxes needed will be 13775/4000=3.44, or at least 4 boxes will be required.

We also note that 4 boxes will hold 16000 g, and we only need to pack 13775g, so there is a lot of margin.

We can proceed to do the mechanical way, fill in order of apple, banoffee, custard, and finally rhubarb pies.Following table shows how we fill, naively: box content Remaining to pack
Box A B C R Weight A B C R
0 4 8 3 5 (original order)
1 4 1 0 0 3525 0 7 3 5
2 0 5 0 0 3625 0 2 3 5
3 0 2 3 0 3250 0 0 0 5
4 0 0 0 5 3375 0 0 0 0
Total weight 13775 g

So that does the job, 4 boxes (minimum) with none exceeding 4000 g to pack a total of 13775 g of pies.

The table represents a linear function. The rate of change between the points (–5, 10) and (–4, 5) is –5. What is the rate of ch

vladimir1956 [14]

<h2>Answer:</h2>

The rate of change between the points (–3, 0) and (–2, –5) is:

-5

<h2>Step-by-step explanation:</h2>

The rate of change between the points (-5, 10) and (-4, 5) is -5.

Now we are asked to find the average rate of change between (-3,0) and (-2,-5)

We know that the average rate of change between two points (a,b) and (c,d) is calculated by the formula:

$Rate\ of\ change=\dfrac{d-b}{c-a}$

Here we have:

(a,b)=(-3,0) and (c,d)=(-2,-5)

Hence, the average rate of change is:

$Rate\ of\ change=\dfrac{-5-0}{-2-(-3)}\\\\\\Rate\ of\ change=\dfrac{-5}{-2+3}\\\\\\Rate\ of\ change=-5$

Also, we know that for any linear function the average rate of change is same between any two points.

Hence, the answer is:

-5

Please find measure of angle s. PLEASE HELP FAST!!

Studentka2010 [4]

Answer:

Step-by-step explanation:

15x-31 = 9x+11

6x-31 = 11

6x = 42

x = 7

15x -31 + 9x + 11 + s = 180

15(7) -31 + 9(7) + 11 + s = 180

105 - 31 + 63 + 11 + s = 180

153 + s = 180

s = 27
