Answer:

P ≈ 25 units

Step-by-step explanation:

LM = 12 units ( horizontal line )

use the distance formula to find length of other 2 sides.

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = L (- 3, 2) and (x₂, y₂ ) = M (3, 5 )

LM = [tex]\sqrt{3-(-3))^2+(5-2)^2}[/tex]

     = [tex]\sqrt{(3+3)^2+3^2}[/tex]

     = [tex]\sqrt{6^2+9}[/tex]

     = [tex]\sqrt{36+9}[/tex]

     = [tex]\sqrt{45}[/tex]

Repeat with (x₁, y₁ ) = M (3, 5) and (x₂, y₂ ) = N (9, 2)

MN = [tex]\sqrt{(9-3)^2+(2-5)^2}[/tex]

     = [tex]\sqrt{6^2+(-3)^2}[/tex]

     = [tex]\sqrt{36+9}[/tex]

     = [tex]\sqrt{45}[/tex]

Then perimeter P is the sum of the 3 sides

P = 12 + [tex]\sqrt{45}[/tex] + [tex]\sqrt{45}[/tex] = 12 + 2[tex]\sqrt{45}[/tex] ≈ 25 units ( to the nearest unit )

70+50=120

or

180-(70+50)=60

angles on a straight line add up to 180°

Answer:

e= -1/2

Step-by-step explanation:

(4/3) +5/3 = (-6e - 5/3) +5/3

4/3 +5/3  = -6e

(3)/-6 = (-6e)/-6

e = -1/2

Answer:

A line segment has a two endpoint connect by a line.

UT isn't connected by a line

Answer:

Line segment UT is not shown in the drawing.

They both are arithmetic sequences.

Step-by-step explanation:

They are arithmetic sequences because they both follow a pattern the first set is going by 2 the second is going by 1. Hope this helps!!!

∠1 and ∠4 are corresponding angles has the same shape and size. ∠1 and ∠3 are diagonal from each other and ∠15 and ∠9 make a straight line.

Parallel lines represent coplanar endless straight lines in geometry that never intersect. Within a single three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.

Euclid's parallel postulate deals with parallel lines. Euclidean geometry is indeed a particular example of this sort of geometry, and parallelism is essentially a feature of affine geometries.

∠1 and ∠4 are corresponding angles has the same shape and size

∠1 and ∠3 are diagonal from each other

∠15 and ∠9 make a straight line

Therefore, ∠1 and ∠4 are corresponding angles has the same shape and size. ∠1 and ∠3 are diagonal from each other and ∠15 and ∠9 make a straight line.

Answer: (1/2, -1)

Step-by-step explanation: The coordinates of point S can be found using the midpoint formula for the hypotenuse RT, since S is the midpoint of RT. The midpoint formula is:

Midpoint of RT = ( (x1 + x2)/2 , (y1 + y2)/2 )

Using the coordinates of R and T, we get:

Midpoint of RT = ( (-1 + 2)/2 , (1 - 3)/2 )

= (1/2, -1)

Therefore, the location of point S is (1/2, -1).

Answer:

150Ft^2

Step-by-step explanation:

The area of a parallelogram is A=BH where B is base length and H is height. I'm not sure why there is information about a triangular base, maybe an illustration would help. But with the information provided, the base times  height is equal to 150 Ft^2. Check out the Kahn Academy video for a better explanation

Answer:

Im guessing 252 is the answer, 42 mold spores were found 14 weeks ago and each 7 weeks it trples right? so two 7 weeks fit in 14 weeks so we would multiply 42 x 2 and which gives us 84 multiply that by 3 since it triples every 7 weeks. And there's your answer, btw don't take this for granted my math is rusty (':

Answer:

1 tenth and 9 hundreds

Step-by-step explanation:

Ok so this is not a gud explanation but believe me that answer is correct

a tenth is 10% out of a hundred so thats 10/100 and since the 9 hundreds is already there 10/100+ 9/100= 19/100

Hope you have a gud day :)

Answer:

Total number of kilometers in the ride = k

Number of kilometers Garret has already biked = 5

Number of kilometers left in the ride = 5-k

Number of minutes Garret takes per kilometer = 4

Therefore, the image shown is correct.

Answer:

Given the equation y = -16t^2 + 96t + 3, we know a = -16, b = 96, c = 3.

Let's solve for h in this problem.  

h = -b/2a

h = -(96) / 2(-16)

h = -96 / -32

h = 3 seconds

Now let's add t=3 to our equation:

y = -16t^2 + 96t + 3

y = -16*(3)^2 + 96*(3)+ 3

y = -144 + 288 + 3

We now know that the vertex is (3,147), which means that the ball's maximum height is 147 feet.

Answer:

Step-by-step explanation:

Find the height at   h(0)   and   h(1)

h(0) = 3 ft

h(1) = -16 + 32 + 3 = 19 ft

It takes 1 second to go from 3 feet to 19 feet

  (19-3) ft / 1 sec = 16 ft/sec

The closest answer to the real value is 480/8 is 60. This is an underestimate.

Answer:

C

Step-by-step explanation:

Whenever you see a variable with an exponent (in parentheses) with another exponent (outside of the parentheses), you need to multiply them together.

[tex]2 \times 6 = 12[/tex]

Now that we only have b^4 x b^12, you might think we need to multiply the exponents again, but that would be wrong.

The only case where you should be multiplying exponents would be in the case of the first step.

Instead, we need to add them.

[tex] { b}^{4 + 12 = 16} [/tex]

Now we know our answer is C.
