Answer: 10 hours

Explanation:

Bill = $720

Material = $375

Labour = $34.50x

375 + 34.5x = 720

34.5x = 345

x =10

If you flip two coins at once, will at least one coin land on heads?

anzhelika [568]

Answer:

There is 3 out of 4 chance you will get one head.

You are not guaranteed to get a head

Step-by-step explanation:

Lets determine the sample space

HH HT TH TT

These are the 4 things that can happen when we flip to coins

We want at least one head

3 of the 4 choices have at least 1 head

P (at least one head) = 3/4

The scouts packed 9 boxes of different kinds of chips for their trip. Each box had 10 bags of chips. These clues show what they

Katarina [22]

The scouts eat 51 bags of chips on their trip

<h3>How to determine the number of bags of chips?</h3>

The given parameters are:

Boxes = 9

Bag = 10 chips

2 full boxes of potato chips and 3 bags left over.

This represents:

Potato chips = 2 * 10 + 3

Potato chips = 23 i.e. 23 bags potato chips are left over

1 fewer box of nacho chips than potato chips, with no bags left over

This represents

Nacho chips = (2 - 1) * 10

Nacho chips = 10 i.e. 10 bags of nacho chips are left over

The loose bags of potato chips is 3.

So, we have:

Barbecue chips = 2 * 3 bags

Barbecue chips = 6 bags

At this point, we have:

Potato chips = 23 bags
Nacho chips = 10 bags
Barbecue chips = 6 bags

The total number of bags left over is

Total = 23 + 10 + 6

Total = 39

The number of bags eaten is:

Eaten = 9 * 10 - 39

Evaluate

Eaten = 51

Hence, the scouts eat 51 bags of chips on their trip

Question 3 (4 MARKS) Find the equation of the tangents to the curve of the function with rule y = x^2 at the points where x = a

Arte-miy333 [17]

Answer:

(0 , -a²)

Step-by-step explanation:

tangent at x = a and x = -a

y = x² (a , a²) and (-a , a²) must be on the curve and tangent to curve

gradient dy/dx = 2x

slope (m) at x = a is <u>2a</u> and slope (m') at x=-a is<u> -2a</u>

line1: (y - a²) / (x - a) = 2a

y - a² = 2a (x - a) y = 2ax - a² ... (1)

line2: (y - a²) / (x + a) = - 2a y = -2ax- a² ... (2)

(1) - (2): 4ax = 0 a≠0 x = 0

y = - a²

If M is the midpoint of AB, find the coordinates of A if M(-3, 5) and B(6, -11)

Luden [163]

midpoint= (x, y)

where x=(x1 + x2)/2

y=(y1 + y2)/2

x1=-3, x2=6, y1=5, y2=-11

so x=(-3 + 6)/2= 3/2

y=(5 + -11)/2= (5-11)/2= -6/2= -3

so mid point =(3/2, -3)

hope this helps
