Answer:

Groceries Galore

Step-by-step explanation:

1) Find the value of 1 egg for each shop.

Max's Market:

2.04 ÷ 6

= £0.34

Groceries Galore:

2.64 ÷ 8

= £0.33

Fancy Foodstuffs:

4.08 ÷ 12

= £0.34

Therefore, Groceries Galore's price per egg is cheaper.

Answer:

Groceries Galore

Step-by-step explanation:

we have to calculate the price of 2 eggs

in each shop apart ,and then we can infer

which shop offers the cheaper price.

…………………………………………………………

• At Max's market :

2 egg costs 2,04÷3 = £0,68

• At Groceries Galore :

2 egg costs 2,64÷4 = £0,66

• At Fancy Foodstuffs :

4,08÷6 = £0,68

………………………………

Conclusion :

Groceries Galore Offers the Lower price.

Note : we can just determine

the price of one egg in each store ,and then compare.

The graph represents the trigonometric function y = cotx option (C) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have shown a trigonometric graph in the picture.

As we know:

At x = 0

tan0 = 0

But cotx at x = 0 does not defined.

The csc x and sec x are the reciprocal of sinx and cosx and the sinx and cos have a sinusoidal graph.

Thus, the graph represents the trigonometric function y = cotx option (C) is correct.

Answer:

4.11 yards/uniform

Step-by-step explanation:

We aren't told that there will be any differences in the uniforms among the 16 concert and 20 symphonic band students.  No information on sizes, styles, or anything else.

In the absence of this information, we must assume all uniforms are the same.

(16 + 20) = 36 students/uniforms

148 yards of material

148 yards/36 uniforms = 4.11 yards per uniform.

The value of the equation a + b is 12

The system of equations is given as:

3a + 6b = 45

2a - 2b = 12

Multiply the second equation by 1.5

3a - 3b = 18

Subtract this equation from the first equation to eliminate a

9b = 27

Divide by 9

b = 3

Substitute b = 3 in 2a - 2b = 12

2a - 2*3 = 12

Divide through by 2

a - 3 = 6

Add 3 to both sides

a = 9

So, we have:

a + b = 9 + 3

Evaluate

a + b = 12

Hence, the value of the equation a + b is 12

The rise and run that would give us a similar right triangle on the same given line is: B. a rise of 8 and a run of 6.

The rise/run of any two points on the same line are have the same slope value.

Given the coordinates:

The rise of triangle ABC = change in y = 4 units

The run of triangle ABC = change in x = 3 units

Rise/run = 4/3

Therefore, a rise of 8 and a run of  6 would give us: 8/6 = 4/3.

This will give us a triangle similar to triangle ABC.

Therefore, the answer is: B. a rise of 8 and a run of 6.

Answer:

See below for both parts

Step-by-step explanation:

A)

Coupon Price:

$25 - 15% ($3.75) = $21.25

10% = 2.50

5% = 1.25

After taking the discount coupon off the final price is $21.25

B)

20% is given as a tip.

20% of $21.25 = $4.25

10% = 2.125

$21.25 + $4.25 = $25.50

Final price with tip is $25.50

Answer: y = -x + 5

Step-by-step explanation:

      A slope-intercept equation is in the form y = mx + b where m is the slope and b is the y-intercept. Since we are given the slope, we will plug it in with the point they gave us, and solve for b.

y = mx + b

(1) = (-1)(4) + b

1 = -4 + b

5 = b

      Lastly, we will write our equation by substituting m with -1 and b with 5.

y = mx + b

y = -1x + 5 or y = -x + 5

Answer:

11:18

Step-by-step explanation:

the lowest common multiple [meaning the nearest possible time these clocks will be ringing at the same time] of 42 and 56 is 168

(56 x 3 = 168 ; 42 x 4 = 168)

So, in 168 minutes, the clock will ring together again.

Now, we need to add 168 minutes to 08:30

(168 can be made up of 2 hours and 48 minutes [120 + 48 = 168])

08:30 + 2 hours = 10:30

10:30 + 48 minutes = 11:18

So, at 11:18, these clocks will ring together again

Step-by-step explanation:

If the subset y is the empty set, then the statement is false. That is the counterexample.

We know that for an invertible function, we always have that:

[tex]f(x) = y\\f^{-1}(y) = x[/tex]

Now, the range of f(x) is the set b. This means that the domain of the inverse is the set b. Such that:

f^{-1} is defined on b→a

Now we want to work on a subset y ⊆ b.

And here comes the problem.

The empty set {∅} is a subset of ay other set. So, if y is the empty set, there are no elements where we can evaluate the inverse function. From that counterexample, we conclude that the statement is false.

Problem 1

Reason:

21/24 = (7*3)/(8*3) = 7/8

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

Problem 2

Work Shown:

1 hour = 60 min

(5/6)*(1 hour) = (5/6)*(60 min)

5/6 of an hour = 50 min

1 hr + 30 min = 60 min + 30 min = 90 min

The first show is 90 minutes. Add on two more shows that are 50 min each to get 90+50+50 = 190 minutes used up

4 hours = 4*60 = 240 min

240 - 190 = 50 min

There are 50 minutes left on the tape.

1 1/2 = 1 + 1/2 = 1 + 0.5 = 1.5

6/(1.5) = 4

Each 6 meter board is cut into 4 equal pieces each 1.5 meters long

There are 6 boards this applies to which means so far that's 6*4 = 24 pieces

Now to the other 6 boards.

3/4 = 0.75

6/(0.75) = 8

Each of the other 6 boards are cut into 8 equal pieces of 0.75 meters each

That's another 6*8 = 48 pieces

In total there are 24+48 = 72 pieces

When cutting into wood, there always is a small sliver that is discarded. While small, these slivers do add up. So yes there is some waste. Unfortunately, we don't have enough info to calculate. We would need to know the width of the saw blade.
