Answer:

1. w = nr

2. His wage is £52.00

Step-by-step explanation:

1. Given that wages is a function of number of hours worked multiplied by hourly rate

Where n represents hours and r represents rate.

Wage formula is as follows;

Wage (w) = hours (n) * rate (r)

w = n * r

w = nr

2. If he worked 5 hours at a rate of £10.40 per hour

This means

n = 5

r = 10.40

His wage is as follows;

w = nr

w = 5 * £10.40

w = £52.00

Hence, his wage is £52.00

Final answer:

Explanation of Gordon's wages formula and a calculation example for working 5 hours at a specific rate.

Explanation:

The formula for calculating Gordon's wages, w, is given by multiplying the number of hours he works, n, by his hourly rate, r.

A formula for Gordon's wages: w = n * r

Wages earned by Gordon working 5 hours at a rate of £10.40 per hour:

Substitute n = 5 and r = £10.40 into the formula:

w = 5 * £10.40

= £52

The wage Gordon would earn if he worked 5 hours at a rate of £10.40 per hour is £52.

The sequence g(n) is a geometric sequence with an explicit formula of g(n) = (2/3)^n * 900 grams.

The sequence g(n) represents the amount of contaminants (in grams) that remains at the beginning of the nth hour. Each hour, a third of the contaminants is filtered out. To determine whether g(n) is an arithmetic or geometric sequence, we need to examine the change in the amount of contaminants from one hour to the next.

Let's look at the first few terms of the sequence:

From the pattern, we can see that each term of g(n) is obtained by multiplying the previous term by 2/3. Therefore, g(n) is a geometric sequence.

The explicit formula for the sequence g(n) can be written as g(n) = (2/3)^n * 900 grams.

Answer:

There will be 200g of aluminium.

Step-by-step explanation:

We use a rule of three to solve this question.

However, the relationship between the variables are inverse, which means that we use an inverse rule of three. This means that we are going to multiply the values laterally, instead of diagonally(cross multiplication).

We have these following relationships:

600g aluminum - 40g tim

xg aluminium - 120g tin

Multiplying laterally:

[tex]120x = 600*40[/tex]

[tex]x = \frac{600*40}{120}[/tex]

[tex]x = 200[/tex]

There will be 200g of aluminium.

Final Answer:

When there is 120 grams of tin, there will be 200 grams of aluminum.

Explanation:

In problems involving inverse variation, the formula that describes the relationship between two variables (in this case, aluminum and tin) is as follows:
k = xy
where:
- k is the constant of variation,
- x is the amount of aluminum, and
- y is the amount of tin.
Given that there are 600 grams of aluminum when there are 40 grams of tin, we can use these values to find the constant of variation (k). We can set up the equation and solve for k with the given values.
[tex]\[ k = 600 \text{ grams of aluminum} \times 40 \text{ grams of tin} \\\\\[ k = 24000 \text{ (constant of variation)} \][/tex]
Now that we have the constant of variation, we know this constant remains the same even when the amounts of aluminum and tin change, providing the inverse relationship is maintained.
Now we want to find out how many grams of aluminum there will be when there is 120 grams of tin. We set up the inverse variation formula and solve for x now that y is given as 120 grams:
k = xy
Given that k = 24000 from our previous calculation, we find x:
[tex]\[ x = \frac{k}{y} \\\\\[ x = \frac{24000}{120} \\\\\[ x = 200 \text{ grams of aluminum} \][/tex]
Therefore, when there is 120 grams of tin, there will be 200 grams of aluminum.

# of hotdogs sold was 75

# of chips sold was 100

Step-by-step explanation:

got it right on edge ya digg

The number of hot dogs is 75 while the number of snacks is 100.

The linear equation to solve the question will be:

h + s = 175 ........ i

2.50h + 0.75s = 262.50 ........ ii

From equation i, s = 175 - h ..... iii

Put equation iii into ii

2.50h + 0.75s = 262.50

2.50h + 0.75(175 - h) = 262.50

2.50h + 131.25 - 0.75h = 262.50

Collect like terms

2.50h - 0.75h = 262.50 - 131.25

1.75h = 131.25

h = 131.25/1.75

h = 75

The number of hot dogs is 75 while the number of snacks is 100.

Final answer:

To determine the page numbers, the product of two consecutive page numbers (n and n+1) was calculated to match 87,912, leading to the solution that Theo's textbook was opened to pages 296 and 297.

Explanation:

To find out to which pages Theo opened his textbook, when the product of the facing pages was 87,912, we should realize that facing pages in books have consecutive numbers. Therefore, if one page is n, the facing page would be n+1. The product of these two pages is n(n+1)= 87,912. We are solving a quadratic equation here.

Starting with an approximation, square roots of numbers near 87,912 can help identify potential page numbers. The square root of 87,912 is a bit less than 300 (since 300² = 90,000). Therefore, one of the page numbers will be just under 300, and the other just above.

Attempting a few calculations, we notice that 296² = 87,616 and 297² = 88,209. Between these two, 296 × 297 = 87,912, giving us the page numbers Theo's book is open to: 296 and 297.

Answer:

y+2=3/4(x+5)

Step-by-step explanation:

The first step is to find the slope of the line. Between the two points, the line rises from a y value of -2 to a y value of 4, or a total rise of 6 units. It also goes to the right from an x value of -5 to an x value of 3, which is a total of 8 units. 6 units of rise over 8 units of run is a total slope of 6/8=3/4. Now, you can use the point slope form for either one of the points (I'll use the leftmost one).

y+2=3/4(x+5)

Hope this helps!

One answer in point slope form: y + 2 = (3/4)(x + 5)

Answer in slope intercept form: y = (3/4)x + 7/4

Answer in standard form: 3x-4y = -7

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

Explanation:

First we need the slope of the line

Find the slope of the line through (x1,y1) = (-5,-2) and (x2,y2) = (3,4)

m = (y2 - y1)/(x2 - x1)

m = (4 - (-2))/(3 - (-5))

m = (4 + 2)/(3 + 5)

m = 6/8

m = 3/4

-------

Plug m = 3/4 and (x1,y1) = (-5,-2) into the point slope formula. Solve for y.

y - y1 = m(x - x1)

y - (-2) = (3/4)(x - (-5))

y + 2 = (3/4)(x + 5)

y + 2 = (3/4)x + (3/4)*5 ... distribute

y + 2 = (3/4)*x + 15/4

y + 2 - 2 = (3/4)*x + 15/4 - 2 ... subtract 2 from both sides

y = (3/4)x + 15/4 - 8/4

y = (3/4)x + (15-8)/4

y = (3/4)x + 7/4

This equation is in slope intercept form y = mx+b

m = 3/4 is the slope, b = 7/4 is the y intercept

-------

Multiply both sides by 4 to help convert to standard form

y = (3/4)x + 7/4

4y = 3x+7

-7 = 3x-4y

3x-4y = -7

This is in the form Ax+By = C

A = 3, B = -4, C = -7

Step-by-step explanation:

Answer:

Step-by-step explanation:

No of total brown = 2 + 1 = 3 .

probability = 3 / 6

no of males = 2

probability

= 2 / 6

= 1 /3

no of person who is both male and brown = 1

probability = 1 /6

Required probability

= probability of being brown + probability of being male - probability of being both

= 1 / 2 + 1 / 3 - 1 /6

= 4 / 6

= 2 / 3 .

Final answer:

The probability of a friend getting a puppy that is male, brown, or both is 2/3, which is calculated by adding the probability of getting a male puppy and a brown puppy, then subtracting the probability of the overlap (brown male).

Explanation:

The student's question concerns the probability of a friend receiving a puppy that is male, brown, or both, given the conditions of the puppies provided. To calculate this probability, we consider all possible favorable outcomes divided by the total number of outcomes. There are 2 males (1 brown, 1 white) and 4 females (2 brown, 4 total), making a total of 6 puppies. A friend can receive either a male puppy (2 out of 6) or a brown puppy (3 out of 6, since we do not count the brown male twice). Thus, the probabilities need to be added together and the intersection (the brown male counted in both categories) subtracted to avoid overcounting.

We calculate the probability as P(Male) + P(Brown) - P(Brown and Male) = 2/6 + 3/6 - 1/6 = 4/6 or 2/3. Therefore, the probability of a friend getting a puppy that is male, brown, or both is 2/3.
