The coordinates of point T are (0,2). The midpoint of ST is (7, -4). Find the coordinates of point S.
Answer: The coordinates of point S is (14,-10).
Step-by-step explanation:
Midpoint of line joining [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by :-
[tex](x,y)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
Given, The coordinates of point T are (0,2). The midpoint of ST is (7, -4).
Let (a,b) be the coordinates of point S.
Then,
[tex](7,-4)=(\dfrac{0+a}{2},\dfrac{2+b}{2})\\\\\Rightarrow\ 7=\dfrac{a}{2},\ \ \ -4=\dfrac{2+b}{2}\\\\\Rightarrow\ a=7\times 2= 14, \ \ 2+b= 2\times-4 =-8\\\\\Rightarrow\ a=14,\ \ \ 2+b=-8\\\\\Rightarrow\ a=14, \ b= -8-2=6--10\\\\\Rightarrow\ a=14,\ b=-10[/tex]
Hence, the coordinates of point S is (14,-10).
solve the equation below for x
2/3(x-18y)=6y
Answer:
[tex]x = 27y[/tex]
Step-by-step explanation:
[tex]\dfrac{2}{3}(x - 18y) = 6y[/tex]
Multiply both sides by 3/2.
[tex]\dfrac{3}{2} \times \dfrac{2}{3}(x - 18y) = \dfrac{3}{2} \times 6y[/tex]
[tex]x - 18y = 9y[/tex]
Add 18y to both sides.
[tex]x = 27y[/tex]
Answer:
x=27y

Four people have found the perimeter of a forest using different methods their results are given in the table Order them from least to greatest A)Jason,Mika,Leon B)Ashley,Jason,Leon C)Mika,Ashley,Jason,Leon D) Leon,Mika,Jason,Ashley
Answer:
LEON (2.1), JASON (2.4), ASHLEY (2.5), MIKA (2.6)
Step-by-step explanation:
To order their perimeter from the least to the greatest, express all perimeters in decimals:
LEON = √17 - 2 = 4.1 - 2 = 2.1
MIKA = 1 + π/2 = 1 + 22/7*½ = 1 + 22/14 = 1 + 1.6 = 2.6
JASON = 12/5 = 2⅖ = 2.4
ASHLEY = 2.5
From least to greatest, we have: LEON (2.1), JASON (2.4), ASHLEY (2.5), MIKA (2.6)

11. 10:00 am to 7:00 pm
12. 5:45 am to 11:20 am
13.6:00 pm to 9:48 pm
Answer:
11. 9hrs
12. 5hrs 35min
13. 3hrs 48 min
Step-by-step explanation:
Makes it a bit easier if you convert to 24 hr time.
11. 10 - 19 is 9hrs
12. 545-1120 is 11-5 20-45 -> 6hrs -25min -> 5hrs 35min
13. 1800 - 2148 is 21-18 48-00 -> 3hrs 48 min
Answer:
11. 9h
12. 5h 35 min
13. 3h 48min
Step-by-step explanation:
11.
here,
time elapsed = ∆t = final time - initial time
= 7 pm - 10 am
= (12+7) h - 10 h {turn pm into am by adding 12 and converting both into hour and min}
= 9 h
12.
similarly,
time elapsed = ∆t = final time - initial time
= 11 h 20 min - 5 h 45 min
= 5 h 35 min
13.
similarly,
time elapsed = ∆t = final time - initial time
= 9 h 48min - 6 h
= 3h 58min

Point M is on line segment LN. Given LN = 9, MN = 4x, and LM=5x
determine the numerical length of MN
Answer : MN =
Answer:
MN = 4
Step-by-step explanation:
Given that L, M, N are collinear,
LN = 9,
MN = 4x
LM = 5x
Required:
Length of MN
SOLUTION:
To calculate the numerical length of MN, we need to find the value of x.
To find the value of x, generate an equation to solve for x as follows:
[tex] LM + MN = LN [/tex] (segment addition postulate)
[tex] 5x + 4x = 9 [/tex] (substitution)
Solve for x
[tex] 9x = 9 [/tex]
Divide both sides by 9
[tex] \frac{9x}{9} = \frac{9}{9} [/tex]
[tex] x = 1 [/tex]
MN = 4x
plug in the value of x
MN = 4(1) = 4
solve by substitution y=2x-1 y=3x+1

An adult usually has 32 teeth. People sometimes lose some of their teeth. Pat has only 5/8 of her teeth left. How many teeth has she lost?
Answer:
twenty teeth
Step-by-step explanation:
32:8=4
4•5=20
Answer:
Pat has lost 12 teeth.
I got a calculator and divided 32 by 8, then timed that answer (4) by 3.
32 ÷ 8 = 4
4 x 3 = 12
If the question had asked how many teeth Pat has, the answer would be 20, but that isn't correct for this question. It asks how many teeth she has lost, and that would be 12.

Perform the indicated operation. 1 and 2/3 plus 5 and 3/8
Answer:
7 1/24
Step-by-step explanation:
1 2/3+5 3/8=?
first you need to find the least common multiple between 2/3 and 3/8.
the lcm would be 24, so 24 would be your new denominator for both fractions, but the numerators will change to how much you just multiplied each denominator by to get 24. 8x3 is 24, so you would multiply 3x3 to get the new numerator: 9. 3x8 is 24, so you multiply 2x8 to get the new numerator for that fraction:16.
so your new fractions are 1 16/24 + 5 9/24
now you add 16+9=25 (25/24, which becomes 1 1/24), so then you have another whole number: +1, and you add it to 5+1, so no it's 5+1+1=7
so the answer would be 7 1/24

The bells are adding a new room to their house. The room will be a cube with volume of 4,913 feet cubed. They are going to put in hardwood floors, and the contractor charged $5 per square foot. How much will the j hardwood floors cost?
Answer:
$1445
Step-by-step explanation:
The side length of the room is the cube root of the volume of the cube:
s = ∛4913 = 17 . . . . feet
The area of the floor is the square of this side length:
A = (17 ft)² = 289 ft²
The cost of the floor is $5 for each square foot:
cost = ($5/ft²)(289 ft²) = $1445
The hardwood floor will cost $1445.
