Answer:

y=21-3x  and y=18-2x

Step-by-step explanation:

Ok, so we have candle A, which is 21 inches and burns 3 inches every hour. in slope-intercept form, the hours would be the x, the 21 is our y intercept. So the first equatio would be y=-3x+21 (negative slope, because the height of the candle is going down). Candle b, which is 18 inches, burns away 2 inches each hour. We can make -2 the slope (negative 2, since the candle is  being burned away, not being added to), and the 18 our y intercept. So the two equations would be

y=21-3x

and

y=18-2x

Answer:

As you didn't add the graph, I will for you.

Step-by-step explanation:

The correct answer is Minneapolis because as you can see Aspen did not change as dramatically as Minneapolis.

The start of January and the middle of March, Minneapolis, or function M(t), had a larger average rate of change. It means that Minneapolis experiences a greater increase in temperature than Aspen does.

A mathematical formula, rule, or legislation that establishes the link between the independent variable and the dependent variable (the dependent variable). In mathematics and the sciences, functions are fundamental for constructing physical relationships.

In the beginning of January, Aspen's temperature was 35° F, and in the middle of March, it was 48° F. 3.5 months later Minneapolis has lows of 25 degrees Fahrenheit in January and highs of 50 degrees Fahrenheit in the middle of March (at 3.5 months).

So, the average rate of change of temperature of Aspen between the points (1, 35) and (3.5, 48) exists

[tex]$\frac{y_2-y 1}{x_2-x_1}=\frac{48-35}{3.5-1}=5.2$[/tex]

The average rate of change of temperature of Minneapolis between the points (1, 25) and (3.5, 50) is [tex]$\frac{50-25}{3.5-1}=10$[/tex]

Thus, from the start of January and the middle of March, Minneapolis, or function M(t), had a larger average rate of change. It means that Minneapolis experiences a greater increase in temperature than Aspen does.

Answer: 17.92 feet

Step-by-step explanation:

From the question, we are informed that the estimation on a scale drawing of a fence is that 3.75 inches = 24 feet.

Based on the above, 1 inch will be:

= 24/3.75

= 6.4 feet

Therefore, the actual length of a second fence that is 2.8 inches in the drawing will be:

= 6.4 × 2.8

= 17.92 feet

Answer:

the circumference of this circle is approximately 25.12 cm with π as 3.14.

Step-by-step explanation:

circumference of a circle is technically a perimeter of a circle.

we find the circumference of a circle by using the following formula :

c = 2πr                                   or                                 c = πd

r represents the radius                                             d represents the diameter

since 4 yds here is a radius, we use the left formula i placed above. then, we substitute the numbers in. pi represents 3.14 as said in your question. even if you use 22/7, you will still get around the same result.

c = 2πr

c = 2(3.14)4

c = 6.28(4)

c = 25.12 yds

therefore, the circumference of this circle is approximately 25.12 yds.

Answer:

A = (b1 + b2)h/2

Step-by-step explanation:

The shape given is a trapezoid having two parallel sides which can be labelled b1 and b2 respectively. The distance between the two parallel sides is the height of the trapezoid, which is labelled h.

Area of a trapezoid is given as:

A = (b1 + b2)h/2

Answer:

$50

Step-by-step explanation:

Given data

We are given that the price is $40

the markup percent is 25%

Hence the price will be

40+25% of 40

=40+ 25/100*40

=40+ 0.25*40

=40+10

=$50

Therefore, the price of the dress is $50

Answer:

Step-by-step explanation:

(a) The length and breadth of the playground as measured by the surveyor are 20 m and 13 m respectively to nearest metre.

Since the actual length is x m and breadth is y m, then;

i.               x ≥ 20 m or x ≤ 20 m

ii.              y ≥ 13 m or y ≤ 13 m

(b) perimeter of the playground = 2 (length + breadth)

                                                     = 2 ( 20 + 13)

                                                     = 2 x 33

                                                     = 66 m

The range of values of the perimeter = 65.4 m < perimeter < 66.5 m

ii. area of the playground = length x breadth

                                          = 20 x 13

                                         = 260 [tex]m^{2}[/tex]

The range of values of the area = 259.4 [tex]m^{2}[/tex] < Area <  260.5 [tex]m^{2}[/tex]

Answer: 25

Step-by-step explanation:

From the question, we are informed that the piece of rural land sold ten years ago for 40000 and that the price for the same land this year is $800 more per acre, and it sold for 60000.

The size of the piece of land in acres will then be:

40000 + 800x = 60000

800x = 60000 - 40000

800x = 20000

x = 20000/800

x = 25

The land is 25 acres

Answer: 25

Step-by-step explanation:

40000 + 800x = 60000800x = 60000 - 40000800x = 20000x = 20000/800x = 25

Answer:

Step-by-step explanation:

It is helpful to remember that opposite angles of an inscribed quadrilateral are supplementary. This lets you find the value of m.

  ∠A +∠K = 180°

  8m° +10m° = 180°

  18m = 180

  m = 180/18 = 10

Using this value we can find ...

  ∠H = 5m° = 5·10° = 50°

  ∠A = 8m° = 8·10° = 80°

  ∠W = 180° -∠H = 180° -50° = 130°
