Answer:

y=22    x=18

Step-by-step explanation:

Step-by-step explanation:

first we need to find the slope of the line.

the slope is the ratio of "y coordinate change / x coordinate change" when going from one point to the other.

we see here

x changes by -4 (from -4 to -8).

y changes by +3 (from -5 to -2).

so, the slope is +3/-4 = -3/4

there are two main forms for the equation of a line :

the slope-intercept form

y = ax + b

and the point-slope form

y - y1 = a(x - x1)

where "a" is the slope, and (x1, y1) is a point on the line.

we can pick any point, and I would pick (-4, -5).

so we get as point-slope form

y + 5 = -3/4 × (x + 4)

or for the slope intercept form we simplify the point-slope form

y + 5 = -3/4 x + -3/4 × 4 = -3/4 x - 3

y = -3/4 x - 8

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

Answer:

Basic fact:

area of a triangle = b x h /2

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)

or

4lh ( 8 x 10) + lw (8 x 8

Step-by-step explanation:

Think of the figure as two different figures, the first figure being a rectangular prism with the measurements of 6ft x 2ft x 3ft and the second figure being another rectangular prism with the measurement of 2ft x 4ft x 5ft. The volume of the first prism is 36ft^3 and the second is 40ft^3. Therefore the figure's volume is 76ft^3.

Answer:

volume of a cylinder = [tex]\pi r^2h[/tex] (where r is the radius and h is the height)

diameter = [tex]2r[/tex]  (where r is the radius)

A)  volume of Cup A = [tex]\pi \times 5^2\times20=500\pi \textsf{ cm}^3[/tex]

B) Assuming the volume of the punch bowl is [tex]\dfrac{130000}{3}\pi \textsf{ cm}^3[/tex]

[tex]\implies \dfrac{130000}{3}\pi \div 500\pi=\dfrac{260}{3}=87 \textsf{ (nearest whole number)}[/tex]

C)  volume of Cup B = [tex]\pi \times 10^2\times20=2000\pi\textsf{ cm}^3[/tex]

D)  Assuming the volume of the punch bowl is [tex]\dfrac{130000}{3}\pi \textsf{ cm}^3[/tex]

[tex]\implies \dfrac{130000}{3}\pi \div 2000\pi=\dfrac{65}{3}=22 \textsf{ (nearest whole number)}[/tex]

The equivalent radian measure of 540° is calculated to be 3π using the relation between degree and radian.

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

3π radian

therefore, The equivalent radian measure of 540°  is 3π.

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

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

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

Remember that the area of rectangles is the length times width. So The long side times the short side. There are two rectangles here so find the area of both and add them up.

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.

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

The perimeter of the quadrilateral is approximately 25 units

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
