Angel has a rectangular garden that is 15 feet longer than it is wide. A cement path that is 4 feet wide surrounds the garden. The total area of the path is 632 sq. ft. what are the dimensions of the garden?

Answers

Answer:

43 ft. long, 28 ft. wide, area is 1204 sq. ft.

Explanation:

I had to draw a diagram for this, and I scribbled all over it, so bear with me as I try to describe this:

The garden is x+15 ft long, and x ft wide. The path is x+23 ft long, and x+8 ft wide, because the path adds 4 ft all around. If you cut the path into smaller rectangles, and find the area of the rectangles, the path is concluded have an area of 16x+184 sq. ft. We already know the area of the path is 632 sq. ft, which in equation form is 16x+184=632. If you solve for x, you get 28 ft. That means the width of the garden is 28 ft. If the length is 15 ft. longer than the width, the length is 43 ft. I also calculated the area for just in case you need it. Let me know if this was helpful in the comments.

Solve for C⁰... photo above​

Answers

Answer:

c = 9

Step-by-step explanation:

Since angle d and 59 are on a right angle (indicated by the small square)

We can equate the sum of these angles to 90:

d+59=90

Now we subtract 59 from both sides:

d+59-59=90-59

d=31

Since angles d,c and 140 are on a straight line we can equate the sum of these 3 to 180:

c+d+140=180

Substitute d with 31 from previous working out:

c+31+140=180

Simplify:

c+171=180

Subtract 171 from both sides:

c+171-171=180-171

Simplify:

c= 9

A car travels 60 km at 30 km/hr and then a further 180 km at 160 km/hr. Find the total time taken.

Answers

Answer: 76.8km/hr

Explanation:

PT1

sp1 - 30km/hr

d1 - 60km

60 divided by 30 = 2hrs

PT2

sp2 - 160km/hr

d2 - 180km

180 divided by 30 = 1hr, 7min, 30sec (1.125)

PT3

Total Time Taken - 2hrs + (1:07:30) 1.125 = 3.125hrs

Avg. Speed - (60km + 180km) divided by 3.125hrs

60km + 180km = 240

240km divided by 3.125 = 76.8km/hr

Step-by-step explanation:

we know the three main values

10mm

8mm

8mm

10 x 8 / 2

10 x 8 = 80

80/ 2 = 40

there are 4 of these

40 x 4 = 160

the base is l x w

8 x 8 = base

base = 64

64 + 160 = surface area

surface area = [tex]224mm^{2}[/tex]

the equation for this pyramid would be:

4LH (length x height) + LW( length x width)

Find Two consecutive positive integers such that the square of the larger integer is nineteen more than nine times the smaller integer

Answers

Answer:

9 and 10

Step-by-step explanation:

To start, let's have what we know:

a and b are two consecutive positive integers

a = first integer

b = second integer, 1 greater than variable a

b = a + 1

b^2 = 19 + 9a

To solve this, we would only have to substitute values in

b^2 = 19 + 9a

(a+1)^2 = 19 + 9a

a^2 + 2a +1     = 19 + 9a

       -9a -19    -19 - 9a

a^2 -7a - 18 = 0

a^2 + 2a - 9a - 18

a(a + 2) - 9(a+2) = 0

(a - 9)(a + 2) = 0

So solving this, we would get a = 9 or a = -2. Since this is supposed to be a positive integer, a will be 9.

Solving for b,

b = a + 1

  = 9 + 1

  = 10

Two trains, train A and train B,weigh a total of 240 tons. Train A is heavier than train B. The difference of their weights is 70 tons. What is the weight of each train?

Answers

Answer:

Train A : 155 tons ; Train B : 85 tons

Step-by-step explanation:

Call train A as A, train B as B

A + B = 240t
A - B = 70t

Add these 2 together, we get :
A + B + A - B = 310t
2A = 310t (B-B = 0)

So, A = 155
B = 240 - 155 = 85

what is the relation between radian and degree?

The value of 180° is equivalent to π radian.

π radian= 180°

as we know that

180° = π radian

1° = π/180 radian

540° = 540* π/180

C. 22 units

*PLEASE HELP ME WITH THIS! (ONLY IF YOU CAN!)*

Answers

The perimeter of a shape is the sum of its side lengths

The perimeter of the quadrilateral is approximately 25 units

How to determine the perimeter

The vertices of the quadrilateral MNOP are given as:

M = (-3,4)

N = (-1,4)

O = (4,-5)

P = (2,-5)

Start by calculating the lengths of the side lengths using the following distance formula

[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]

So, we have:

[tex]MN = \sqrt{(-1 +3)^2 + (4 -4)^2} = 2[/tex]

[tex]NO = \sqrt{(4+1)^2 + (-5 -4)^2} \approx 10.3[/tex]

[tex]OP = \sqrt{(2-4)^2 + (-5 +5)^2} =2[/tex]

[tex]PM = \sqrt{(-3-2)^2 + (4+5)^2} \approx 10.3[/tex]

The perimeter is then calculated as:

[tex]P = 2 + 10.3 + 2 +10.3[/tex]

Add

[tex]P = 24.6[/tex]

Approximate

[tex]P = 25[/tex]

Hence, the perimeter of the quadrilateral is approximately 25 units
