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

I'm still doing the rest but number 1 is D
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%

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**

Two triangular prisms are similar. The perimeter of each face of one prism is double the perimeter of the corresponding face of the other prism. How are the surface areas of the figures related? The surface areas are the same. The surface area of the larger prism is 2 times the surface area of the smaller prism. The surface area of the larger prism is 4 times the surface area of the smaller prism. The surface area of the larger prism is 8 times the surface area of the smaller prism.
we know that
if the perimeter of each face of one prism is double the perimeter of the corresponding face of the other prism and the two triangular prisms are similar
then
the scale factor is equal to
so
substitute the value of the scale factor
therefore
the answer is the option
Answer:
The surface area of the larger prism is 4 times the surface area of the smaller prism.

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

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.

In selecting one card from a deck of cards is obtaining a queen and obtaining a 2 mutually exclusive events?
A: Yes/True
B: No/False
Answer:
Mutually exclusive is a statistical term describing two or more events that cannot happen simultaneously. It is commonly used to describe a situation where the occurrence of one outcome supersedes the other.
Since in this question, we have selected one card from a deck, and is obtaining a 2 and a queen.
I think the answer for this would be No/False but if i'm wrong, tell me!

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)
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]
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°

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
Find the area of the circle. Round your answer the nearest whole number, if necessary.
area: about
in.2
Answer:
Area = 314 in.²
Step-by-step explanation:
Radius of the circle = 10 in.
Formula for area of a circle = πr²
Radius (r) = 10 in.
Plug in the value of r into the formula
Area = π*10²
Area = π*100
Area = 314.159
Area = 314 in.² (nearest whole number)
Answer:
The area of circle is 314 in².
Step-by-step explanation:
Given :
Radius of circle = 10 in.To Find :
Area of circleUsing Formula :
[tex]\star{\small{\underline{\boxed{\sf{\red{Area_{(Circle)} = \pi{r}^{2}}}}}}}[/tex]
π = 3.14 r = radiusSolution :
Finding the area of circle by substituting the values in the formula :
[tex] \begin{gathered} \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = \pi{r}^{2}}}} \\ \\ \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = 3.14 \times {(10)}^{2}}}} \\ \\ \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = 3.14 \times {(10 \times 10)}}}} \\ \\ \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = 3.14 \times {(100)}}}} \\ \\ \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = 3.14 \times 100}}} \\ \\ \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = \dfrac{314}{100} \times 100}}} \\ \\\qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = \dfrac{314}{\cancel{100}} \times \cancel{100}}}} \\ \\ \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = 314 \: {in}^{2}}}} \\ \\ \qquad\star{\small{\underline{\boxed{\sf{\pink{Area_{(Circle)} = 314 \: {in}^{2}}}}}}}\end{gathered}[/tex]
Hence, the area of circle is 314 cm².

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
