Answer:

B

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

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: 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

Step-by-step explanation:

y = -½(x-3)²-1

This is the equation of a vertical parabola with vertex at (3,-1). The leading coefficient is negative, so the parabola opens downwards.

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:

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°

x=1, y=-9

Step-by-step explanation:

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:

$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:

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.
