let's assume the temperature on 5th day be x
We know that :
[tex] \boxed{mean = \frac{sum \: \: of \: all \: \: observations}{number \: \: of \: \: observations} }[/tex]
So,
[tex] \hookrightarrow \: 0 = \dfrac{ - 2 + ( - 2) + ( - 2) + ( - 2) + x}{5} [/tex]
[tex] \hookrightarrow \: 0 \times 5= - 2 - 2 - 2 - 2 + x[/tex]
[tex] \hookrightarrow \: 0 = - 8 + x[/tex]
[tex] \hookrightarrow \: x = 8[/tex]
Therefore, temperature on the fifth day was x = 8

Step-by-step explanation:
10- 3/4z = 8
Somebody, please help me! I don't get this!
Answer:
z = 8/3
Step-by-step explanation:
10- 3/4z = 8
Subtract 10 from each side
10-10- 3/4z = 8-10
-3/4z = -2
Multiply each side by -4/3
-3/4z * -4/3 = -2 *4/3
z = 8/3
A steel ball has a volume of 1500 cm.
The density of the ball is 95 g/cm'.
Find the mass of the ball in kg.
Answer:
m=15.78
Step-by-step explanation:
density = volume / mass
subtitute values:
95= 1500/ mass
mass = 1500/95
m= 15.78
2.)Name the number system in which only the whole number less than 5 are used:
Answer:
(a) x = 40°
Step-by-step explanation:
(2x+43)°+(2x-3)°=180°
4x+40°=180°
x=40°
3(x - 5) = 30
I dont know how to solve this
Answer:
x=15
Step-by-step explanation:
3(x-5)=30
First, you would distribute the three to the x and the negative five.
3x-15=30
Then you would add 15 to the 15 to cancel it and to the 30 to make it even.
3x-15=30
+15=+15=
3x=45
Finally, you would divide 3 into both sides, cancelling out the three and fiving you,
x=15
Hope this helped!
Start by distributing the 3 through the parenthses on the left side.
This gives us 3x - 15 = 30.
Now add 15 to both sides to end up with 3x = 45.
Dividing both sides by 3, we fin that x = 15.

Find the area of a triangle with legs that are: 9 mm, 6 mm, and 12 mm.
A. 26.1 mm
B. 12.3 mm
C. 11.6 mm
D. 37 mm?
Answer:
Step-by-step explanation:
a = 9 mm ; b = 6 mm ; c = 12 mm
S = (a + b +c) / 2
[tex]= \dfrac{9 + 6 + 12}{2}\\\\= \dfrac{27}{2}\\\\= 13.5 \ mm[/tex]
S - a = 13.5 - 9 = 4.5 mm
s -b = 13.5 - 6 = 7.5 mm
s -c = 13.5 - 12 = 1.5 mm
Area = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
[tex]= \sqrt{13.5 * 4.5 * 7.5 * 1.5} \\\\= \sqrt{683.4375} \\\\=26.1 \ mm^{2}[/tex]

Findi the value of x
Answer:
By Pythagoras theorem ,
H^2 = P^2 + B^2
H^2 = 4^2 + 3^2
H^2 = 16 + 9
H^2 = 25
H = 5
therefore , value of x = 5
hope that helps uh..☺
Answer:
x = 5
Step-by-step explanation:
Since it's a right triangle, you can use Pythagorean Theorem.
[tex]a^2+b^2=c^2\\3^2+4^2=x^2\\9+16=x^2\\25=x^2\\5=x[/tex]
Solve for p.
−160=22+8(3p−4)
Answer:
[tex]p=-6.25[/tex] or [tex]p=\displaystyle-\frac{25}{4}[/tex]
Step-by-step explanation:
[tex]-160=22+8(3p-4)[/tex]
Our goal here is to isolate p on one side of the equation. We will do this by performing inverse operations on both sides.
Subtract 22 from both sides:
[tex]-160-22=22+8(3p-4)-22\\-182=8(3p-4)[/tex]
Divide both sides by 8:
[tex]-22.75=3p-4[/tex]
Add 4 to both sides:
[tex]-22.75+4=3p-4+4\\-18.75=3p[/tex]
Divide both sides by 3:
[tex]-6.25=p[/tex]
You can also convert this into a fraction:
[tex]p=\displaystyle-\frac{25}{4}[/tex]

8a=4(a-9)
Show work I need help
Answer:
a = -9
Step-by-step explanation:
8a=4(a-9)
Divide each side by 4
8a/4=4(a-9)/4
2a = a-9
Subtract a from each side
2a-a = a-9-a
a = -9
Answer:
-9
Step-by-step explanation:
8a = 4(a-9)
Use the distributive property (Multiply 4 times a, and 4 times -9)
8a = 4a - 36
Bring the 4a to the other side
8a - 4a = -36
Add like terms
4a = -36
Divide both sides by 4 to get a by itself
a = -9

What is the area of this figure?
4 m
3 m
2 m
3 m
2 m
9 m
6 m
5 m
Write your answer using decimals, if necessary.
square meters
Answer:
63
Step-by-step explanation:
Area = large rectangle + small rectangle + triangle
A = (L1 * W1) + (L2 * W2) + 1/2 base * heigth)
A = (9 * 5) + (2 * 3) + 1/2(((2 + 5 + 2) - (3)) * 4))
A = 45 + 6 + 1/2((9 - 3) * 4)
A = 51 + 1/2(6 * 4)
A = 51 + 1/2(24) = 51 + 12 = 63
Solve. x/8 + 2 = 27

JC is making a poster for Bike Safety Week. The diameter of circle A is 16 in.
If the area of circle B is of the area of circle A, what is the area of circle B? Use = 3.14.
Answer:
Circle B has an area of 200.96 in².
Step-by-step explanation:
π = 3.14
radius of circle A = diameter of circle A/2
= 16 in/ 2 = 8 in.
Area = πr² = (3.14)(8²)
= (3.14)(64)
= 200.96 in²
