Answer:
-5n = 1 ⇒ n = -¹/₅ n+15 = (-10) ⇒ n = 25 n/5 = -1/5 ⇒ n = -1 n-13= -12 ⇒ n = 1Step-by-step explanation:
-5n = 1
÷(-5) ÷(-5)
n = -¹/₅
n + 15 = (-10)
-15 -15
n = -25
n/5 = -1/5
×5 ×5
n = -1
n - 13 = -12
+13 +13
n = 1
Answer:
-5n = 1 : n = -¹/₅
n+15 = (-10): n = -25
n/5 = -1/5 : n = -1
n-13= -12: n = 1

The area of a square is given by A=s2, where s is the length of each side of the square. If the area of a square room is 81 square meters, what is the length of one side of the room in meters?
Answer: The length of one side is 9m.
Step-by-step explanation:
If area is 81 square meters, that means A = 81 m^2.
Since A = s^2, we can substitute s^2 for A. Then
(s^2) = 81 m^2
Take the square root of both sides to solve for s:
(s^2)^(1/2) = (81 m^2)^(1/2)
s = 9 m

AR:AB = 1/5 means that AR has length equal to 1/5 of the length of AB.
To find the x coordinate of R, you take 4/5 of the x coordinate of A plus 1/5 of the x coordinate of B:
4/5 * 1 + 1/5 * 4 = 8/5
You do the same for the y coordinate:
4/5 * (-1) + 1/5 * 4 = 0
So the point R has coordinates (8/5, 0).

A surveyor is surveying a street. The surveyor is standing at point P looking down the street at a No Parking sign at point C and a Stop sign at point R. Given PC = 6x-5 meters, PR = 29 meters, CR = 7 meters, and point C is between P and R, what is xin meters?
Answer:
4.5 metresStep-by-step explanation:
If point C is between P and R, then PC+CR = PR.
Given PC = 6x-5
CR = 7 and PR = 29
Required
Find the value of x in metres
Substitute the given values into the formula;
6x-5+7 = 29
6x+2 = 29
subtract 2 from both sides
6x-2+2 = 29-2
6x = 27
Divide both sides by 6
6x/6 = 27/6
x = 27/6
x = 9/2
x = 4.5 metres
Hence the value of x in metres is 4.5metres
A 5kg ball is traveling at the same speed as a 10 kg ball. compared with the 5 kg ball, the 10 kg ball has
1) half the momentum
2) twice the momentum
3) five times the momentum
4) the same momentum
Answer:
2) twice the momentum
Step-by-step explanation:
p=mv
momentum had a directly proportional relationship to mass, what this means is that if you somehow increase the mass of the object twice the momentum will also increase twice, if the mass decreases by 5 times the momentum will also decrease by 5 times. Therefore, since the 10 kg object is twice the mass of the 5 kg object, so is its momentum relative to the 5 kg object. (5×2=10) 2p=2m

Mary Jane is buying paper plates for her big going away party. The fancy plates come in packs of 8. She is inviting 41 guests. How many packs of plates should Mary Jane buy?
41 guests / 8 plates = 5.125 packs
Since you cant buy .125 of a pack, Mary jane has to purchase 6 packs.
Answer:
6 packsStep-by-step explanation:
41 guests = 5.125 packs
8 plates
5 x 8 = 40 plates
6 x 8 = 48 plates
therefore Mary Jane should buy the 6 packs more than enough for her 41 guests.

Answer:
150 square inches
Step-by-step explanation:
The surface area is the exposed area, which would be 6 sides with an area of 25 and 25x6 is 150
Answer:
150 square inches
Step-by-step explanation:
The surface area of the cube is
[tex]S_A=A_1+A_2+A_3+A_4+A_5+A_6[/tex]
but it's a cube so all the areas are the same
[tex]S_A=6A_1[/tex]
and the area of
[tex]A_1=l^2[/tex]
[tex]l=5\\\\A_1=5^2\\\\A_1=25[/tex]
so the surface area is
[tex]S_A=6(25)\\\\S_A=150[/tex]square inches

According to the American music industry, the length of a song is normally distributed with a mean of 240 seconds and standard deviation thirty seconds. Suppose a random sample of fifteen songs is selected from the morning program. what is the probability that the length of the song is between 225 and 260 seconds long?
Answer:
96.89%
Step-by-step explanation:
Find the standard error:
s = σ/√n
s = 30 / √15
s = 7.75
Find the z-scores:
z = (x − μ) / s
z₁ = (225 − 240) / 7.75
z₁ = -1.94
z₂ = (260 − 240) / 7.75
z₂ = 2.58
Find the probability.
P(-1.94 < Z < 2.58) = P(Z<2.58) − P(Z<-1.94)
P(-1.94 < Z < 2.58) = 0.9951 − 0.0262
P(-1.94 < Z < 2.58) = 0.9689
