Answer:

The equation is;

C = kg

c is the cost in $

k is the proportionality constant $/can

g is the number of cans

cost of 5 cans of coffee is $46.25

Step-by-step explanation:

From the question, 2 cans of ground coffee costs $18.50

Let c be the cost and g be the number of ground coffee

18.50 = k * 2

where k is the constant of proportionality;

k = 18.5/2

k = 9.25

So, the cost of 5 coffee cans will be;

c = 9.25 * 5 = $46.25

Answer:D is the answer

Step-by-step explanation:

Answer:

$11.93

Step-by-step explanation:

You can write an equation to represent this scenario, where x is the number of minutes spent on the call and y is the total cost of the call.

[tex]y=0.99x + 5.99[/tex]

Plug in 6 for x:

[tex]y=0.99(6)+5.99[/tex]

Multiply 6 x 0.99, representing the fact it costs 99 cents per each minute spent on the call:

[tex]y=5.94+5.99[/tex]

Add the sum of the $5.99 cost to connect the call, plus the charge ($5.94) for spending six minutes:

[tex]y=11.93[/tex]

Your answer is $11.93!

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, reflection, dilation and rotation.

Dilation is the enlargement or reduction of the size of a figure. If a point A(x, y) is dilated about the center of origin by a factor k, the new point is at A'(kx, ky)

If a point A(x, y) is dilated about the point (a,b) by a factor k, the new point is at A'(k(x - a) + a, k(y - b) + b)

From the image the vertex of the triangle is at (0,0), (-2, 4) and (-2, 0). If the triangle is enlarged by scale factor 1.5 using (4,4)  as the center of enlargement.. Hence the new points are:

For (0,0): (1.5(0 - 4) + 4, 1.5(0 - 4) + 4) = (-2, -2)

For (-2,4): (1.5(-2 - 4) + 4, 1.5(4 - 4) + 4) = (-5, 4)

For (-2, 0): (1.5(-2 - 4) + 4, 1.5(0 - 4) + 4) = (-5, -2)

The approximate change in the value of the function will be 10. Then the correct option is C.

It is the average amount by which the function is modified per unit throughout that time period. It is calculated using the gradient of the line linking the interval's ends on the graph that represents the function. The average rate of change of the function is given as,

Average rate = [f(x₂) - f(x₁)] / [x₂ - x₁]

The function is given below.

f(x) = x² + 4x - 1

The average rate is calculated as,

Average rate = [f(3.1) - f(3)] / [3.1 - 3]

Average rate = [(3.1² + 4(3.1) - 1) - (3² + 4(3) - 1)] / 0.1

Average rate = (21.01 - 20) / (0.10)

Average rate = 1.01 / 0.10

Average rate = 10.1

Average rate ≈ 10

The approximate change in the value of the function will be 10. Then the correct option is C.

Answer:

I think the answer is 24.

Step-by-step explanation:

I think the answer is 24 because if the baseball player hit the bat and ran the base 3 out of 10 times, then you would multiply 8 x 3 to get 24 out of 80. I don't know if this is the correct answer, this is just what I think it may be.

Answer:

10 i guess

cause

8*3=24

3*10=30

Step-by-step explanation:

Since the scale factor of the large to small triangle is 3 : 1, the side lengths of the small triangle are 1/3 of the big triangle side lengths. (such as 8 compared to 24)

Therefore 3x = 30 and x = 10.

No these triangles are not similar.

Step-by-step explanation:

Given Information on First triangle :

Base = 3

Height = 8

Given information on Second triangle :

Base = 4

Height = 10

Area of a Right Angle triangle :

[tex] \frac{base \times height}{2} [/tex]

Area of First triangle :

[tex] \frac{3 \times 8}{2} = \frac{24}{2} \\ \\ = 12[/tex]

Area of Second triangle :

[tex] \frac{4 \times 10}{2} = \frac{40}{2} = 20[/tex]

Their Ratio :

[tex]12:20 = \frac{12}{20} \\ = \frac{3}{5} [/tex]

So I guess no, the triangles are not similar.

Answer:

£36

Step-by-step explanation:

From the question, we are told that School allots £3000 to spend on a trip to the theatre. With regular cost of tickets of £40 each with offer for 1/5 off

Then the cost of each ticket with 1/5 off= (4/5×40)= £32

From the question, A train ticket for the day will cost £20 each.

Then total cost for each of it = £32+£20

=£52

To determine how much money that the school will have left over, If 3 teachers and the maximum number of students attend, can be expressed below by first calculating the number of students.

Let us denote the number of students as "x"

52(x+3)= < 3000

52x + 156 =< 3000

52x =< 3000 - 156

52x =< 2844

X =< 2844/52

s =< 54.69,

The max. Number of students is 54

Total number of people= Number of students + the 3 teachers

= 54+3= 57

Total cost for 57 people= (£52 × 57 people)= £2964

The amount of money the school will have as left over = (£3000 - £2964)

= £36
