Answer: 2000/25 = 80 tiles
Step-by-step explanation:
Date: s=20
equation of surface area of a cube prism: surface area = 6s*2
the surface area to be covered with tiles is requires, the base is not included, so the equation reduces: surface area = 5s*2
subtitute values: surface area = 5(20)*2
= 5(400)
surface area = 2000
area of 2 tile is 5*2 = 25 square inches
2000/25 = 80 tiles

Help!!!!! find the value of x.
Answer:
x = 48
Step-by-step explanation:
The two angles shown in the diagram are supplementary and add to 180° because they form a straight line. We can set up an equation:
x - 12 + 3x = 180
4x - 12 = 180
4x = 192
x = 48
Answer:
[tex]x=42[/tex] ✔︎
Step-by-step explanation:
∠1 + ∠2=1803x+x-12=1804x-12=1804x=180-124x=168x=42°∠1= 3x=3×42=126°
∠2=x-12=42-12= 30°

A video store charges $5 per game rental plus $12 to rent the game system. Write an expression for renting the game system and a number of games.
Answer:
12 + 5X = Y
Step-by-step explanation:
Given that a video store charges $ 5 per game rental plus $ 12 to rent the game system, to write an expression for renting the game system and a number of games the following logical reasoning must be performed:
5 = variable not fixed, depends on the number of games
12 = fixed variable
X = number of games
Y = total value
12 + 5X = Y
Thus, if 5 video games were rented, the equation would operate as follows:
12 + 5x5 = Y
12 + 25 = Y
37 = Y

Line EB is a diameter which splits the circle in the middle so the arc of EB would be half the circle. The arc goes through B and continues to C making the arc longer than half the circle.
An arc that is longer than half a circle would be a major arc.
The answer is: Major Arc

9. If NK = 7x-1, NM = 10x - 13, and KM = 24, find NP.
Answer:
[tex]NP = 24.18[/tex]
Step-by-step explanation:
Given
[tex]NK = 7x - 1[/tex]
[tex]NM = 10x - 13[/tex]
[tex]KM = 24[/tex]
See attachment
Required
Length of NP
First, calculate the value of x
[tex]NK = NM[/tex]
So:
[tex]7x -1 = 10x - 13[/tex]
Collect like terms
[tex]10x - 7x = 13 - 1[/tex]
[tex]3x =12[/tex]
Solve for x
[tex]x = 4[/tex]
To solve for NP, we consider right triangle [tex]\triangle NKP[/tex]
Where
[tex]NK = 7x - 1[/tex]
[tex]NK = 7 * 4 - 1[/tex]
[tex]NK = 27[/tex]
[tex]KP =\frac{1}{2}KM[/tex]
[tex]KP =\frac{1}{2} * 24[/tex]
[tex]KP =12\\[/tex]
Using Pythagoras theorem, we have:
[tex]NK^2 = KP^2 + NP^2[/tex]
[tex]27^2 = 12^2 + NP^2[/tex]
[tex]729 = 144 + NP^2[/tex]
Collect like terms
[tex]NP^2 = 729 - 144[/tex]
[tex]NP^2 = 585[/tex]
Take square roots
[tex]NP = \sqrt{585[/tex]
[tex]NP = 24.18[/tex]

find the measure of each angle indicated
a. 33
b. 36
c. 31
d. 136
Answer:
31
Step-by-step explanation:
Let the missing angle be x.
Sum of angles in a triangle is supplementary,
x + 20 + 129 = 180
x + 149 = 180
x = 180 - 149
x = 31
Answer:
31
Step-by-step explanation:
A triangle is 180 degrees.
129 + 20 = 149
180 - 49 = 33

16/4 + 56 – (3 + 4 - 1)
Answer:
54
Step-by-step explanation:
First solve for brackets then multiplication or division then addition or subtraction
Answer: 52.
Step-by-step explanation: I don't know if you know about PEMDAS, but it basically stands for (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction). So first, we would do Parenthesis. In the parenthesis, we have 3 + 4 - 1. Addition and Subtraction are the same, since they are inverse operations. We would start from left to right, so the addition goes first. 3 + 4 = 7. Now we are left with 7 - 1. 7 - 1 = 6. The equation so far is: 16/4 + 54 - 6. Next, we will do division. 16 ÷ 4 = 4. The equation so far is: 4 + 54 - 6. Now, we have to add 4 + 54 since we are doing it from left and right. 54 + 4 = 58. We are left with 58 - 6. 58 - 6 = 52. So your final answer is 52. Hope this helps!! :) **I tried my best**
What is the value of x in the solution to this system of equations?
5x+2y=67x=3y−7
Question 4 options:
6
18.5
24
11
Answer:
x = 11
Step-by-step explanation:
[tex]x-3y=-7[/tex]
[tex]5x=-2y+67[/tex]
=> [tex]x=\frac{1}{5}(-2y+67)[/tex]
=> [tex]x=-\frac{2}{5}y+\frac{67}{5}[/tex]
=> [tex]-\frac{2}{5}y+\frac{67}{5}-3y=-7[/tex]
=> [tex]-\frac{17}{5}y+\frac{67}{5} =-7[/tex]
=> [tex]\frac{-17}{5}y=-\frac{102}{5}[/tex]
=> y = 6
=> [tex]x=-\frac{2}{5} .6+\frac{67}{5}[/tex]
=> x = 11

Solve 11-Jx+4 = 0 for real
Question for 1 B)
Answer:
x = 117
Step-by-step explanation:
Given
11 - [tex]\sqrt{x+4}[/tex] = 0 ( subtract 11 from both sides )
- [tex]\sqrt{x+4}[/tex] = - 11 ( square both sides )
(- [tex]\sqrt{x+4}[/tex] )² = (- 11)²
x + 4 = 121 ( subtract 4 from both sides )
x = 117

What is the median please help please help
Answer:
54.5
Step-by-step explanation:
To find the median, first we have to put the numbers in ascending/increasing order.
43, 60, 50, 36, 58, 50, 73, 59, 69, 51 is your set
36, 43, 50, 50, 51, 58, 59, 60, 69, 73 is your set in order.
The median is the middle number of the data set. Your set has an even number of entries, so we have to average the 2 middle numbers, which are 51 and 58.
36, 43, 50, 50, 51, 58, 59, 60, 69, 73
51 + 58 = 109
109/2 = 54.5
What is coordinates of point C?
Answer:
(3,6)
Step-by-step explanation:
Using the midpoint segment formula
M(X, Y) = [(ax1+bx2/2, ay1+by2/2)]
Given (-2 -6) and (4,6) divided in the ratio 1:5
X = 1(-2) + 5(4)/1+5
X = -2+20/6
X = 18/6
X = 3
Similarly
Y = 1(-6)+ 5(6)/1+5
Y = -6+30/6
Y = 24/6
Y = 4
Hence the required coordinate of C is (3,6)
in how many years 1600 invested at 5% will amount to 1920
Answer:
principal=1600
rate=5%
amount=1920
time=x
interest=p*t*r/100
=1600*x*5/100
=8000x/100
80x
amount=principal +interest
1920=1600+80x
1920-1600=80x
320/80=x
4=x
therefore after 5 years 1600 amount to 1920 at the rate of 5%

What is the rule of 72?
Answer:
Brainiest please
Step-by-step explanation:
In finance, the rule of 72, the rule of 70 and the rule of 69.3 are methods for estimating an investment's doubling time. The rule number (e.g., 72) is divided by the interest percentage per period (usually years) to obtain the approximate number of periods required for doubling. Although scientific calculators and spreadsheet programs have functions to find the accurate doubling time, the rules are useful for mental calculations and when only a basic calculator is available.
