Answers
The total number of marbles in Marcel's collection is 50.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Marcelo has 6 red marbles in his marble collection. Red marbles make up 12% of all the marbles.
The number of marbles in Marcel's collection is calculated as,
12% of marbles = 6
1% of marbles = 6 / 12
100% of the marbles= ( 6 / 12) x 100
100% of the marbles = 50

Answers
Answer:
7.4
Step-by-step explanation:
1. according to the condition (m+n+s+p+q)/5=12, it means (m+n+s+p+q)=60;
2. the required mean can be calculated:
[(m-4)+(n-3)+(s-6)+(p-2)+(q-8)]/5=[(m+n+s+p+q)-23]/5=[60-23]/5=37/5=7.4.

A town has a population of 2000 and grows at 4. 5% every year. What will be the population after 13 years, to the nearest whole number?.
Answers
Answer:
3544 people
Step-by-step explanation:
We can start by representing this as an exponential function, in the form [tex]y=a(b)^x[/tex]
2000 will be our a, or our initial value. We must convert our multiplier, 4.5% to a decimal, which is 1.045. 13 is our input since it's our number of years where we want to find the population. Now that we have our variables, lets make an equation.
[tex]y=2000(1.045)^13[/tex]
PEMDAS states that we first do exponents, so lets raise 1.045 to the 13th power.
[tex]y=2000(1.77219609724)[/tex]
Now we multiply by 2000!
[tex]y= 3544.39219448[/tex]
Rounded to the nearest whole number is 3544. Therefore, there will be 3,544 people living in the town in 13 years.

Answer:
Question 1: C. 4 × 3 × 2 × [tex]\frac{1}{8}[/tex] × [tex]\frac{1}{8}[/tex] × [tex]\frac{1}{8}[/tex]
Question 2: The volume is [tex]\frac{1}{12}[/tex] or 0.083333333
Question 3: The volume fo the solid figure is 234
Step-by-step explanation:
1. Volume of a rectangular prism = (length × width × height) cubic units
Length = 4 × [tex]\frac{1}{8}[/tex]
Width = 3 × [tex]\frac{1}{8}[/tex]
Height = 2 × [tex]\frac{1}{8}[/tex]
Volume = 4 × [tex]\frac{1}{8}[/tex] × 3 × [tex]\frac{1}{8}[/tex] × 2 × [tex]\frac{1}{8}[/tex]
Volume = 4 × 3 × 2 × [tex]\frac{1}{8}[/tex] × [tex]\frac{1}{8}[/tex] × [tex]\frac{1}{8}[/tex]
So the correct option is:
C. 4 × 3 × 2 × [tex]\frac{1}{8}[/tex] × [tex]\frac{1}{8}[/tex] × [tex]\frac{1}{8}[/tex]
2.
We have to fold the shape into a rectangular prism, look at the picture
Volume of a right rectangular prism = (length × width × height)
Length = [tex]\frac{1}{3}[/tex]
Width = [tex]\frac{1}{3}[/tex]
Height = [tex]\frac{3}{4}[/tex]
Volume = [tex]\frac{1}{3}[/tex] × [tex]\frac{1}{3}[/tex] × [tex]\frac{3}{4}[/tex]
Multiply [tex]\frac{1}{3}[/tex] times [tex]\frac{1}{3}[/tex] by multiplying numerator times numerator and denominator times denominator.
[tex]\dfrac{ 1 \times 1 }{ 3 \times 3 } \times \left( \dfrac{ 3 }{ 4 } \right)[/tex]
Do the multiplications in the fraction [tex]\dfrac{ 1 \times 1 }{ 3 \times 3 }[/tex]
[tex]\dfrac{ 1 }{ 9 } \times \left( \dfrac{ 3 }{ 4 } \right)[/tex]
Multiply [tex]\frac{1}{9}[/tex] times [tex]\frac{3}{4}[/tex] by multiplying numerator times numerator and denominator times denominator.
[tex]\dfrac{ 1 \times 3 }{ 9 \times 4 }[/tex]
Do the multiplications in the fraction [tex]\dfrac{ 1 \times 3 }{ 9 \times 4 }[/tex]
[tex]\frac{3}{36}[/tex]
Reduce the fraction [tex]\frac{3}{36}[/tex] to the lowest terms by extracting and canceling out 3
Fraction form: [tex]\frac{1}{12}[/tex]
or
Decimal form: 0.083333333
So the volume of the right rectangular prism is [tex]\frac{1}{12}[/tex]
3. Look at the picture with the solid figure labeled
We can think of this shape as two different prisms ( A and B)
Volume of A = 4.5 × 6 × 6.5 = 175.5
Volume of B = 3 × 3 × 6.5 = 58.5
Total volume of the whole figure = 175.5 + 58.5
175.5 + 58.5 = 234
So the volume of the solid figure is 234

17. What is the measure, in degrees, of angle x?
Answers
Let ,
130° + y = 180° — ( i )
x + 107° + y = 180° — ( ii )
now ( i )
130° + y = 180°
y = 180° - 130°
y = 50°
now substituting value of y in equation ( i )
[tex]x + 107 + y = 180 \\ x + 107 + 50 = 180 \\ x + 157 = 180 \\ x = 180 - 157 \\ [/tex]
x = 23°

Solve the following equations:
a. 3x + 5y = 8 ,
4x – 3y = 1
b. 6p + 4q = 20,
5p – 2q = 6
Answers
Step-by-step explanation:
a) 3x + 5y = 8
4x - 3y = 1
• using the elimination method:
3x + 5y = 8 (×4)
4x -3y = 1 (×3)
12x + 20y = 32
12x -9y = 3
subract 12x from both equation:
20y - - 9y= 32 -3
20y +9y = 29
29y= 29
y= 29/29
y= 1
- substituting y= 1 in :
4x - 3y= 1
4x - 3(1) = 1
4x -3 = 1
4x = 1 + 3
x = 4/4
x= 1
b) 6p+ 4q = 20
5p - 2q = 6
• using the elimination method:
6p + 4q = 20
5p - 2q = 6 (×2)
6p + 4q = 20
10p - 4q = 12
add 4q + -4q to eliminate q.
6p+ 10p = 20+12
16p = 32
p = 32/ 16
p = 2
- subtituting p = 2 in :
5p - 2q = 6
5(2) -2q =6
10 -2q = 6
-2q = 6 - 10
q = -4 / -2
q = 2
hope this helps you,

Answer:
a. x = 1 / y = 1b. p = 2 / q = 2Step-by-step explanation:
a.3x + 5y = 8 ________( 1 )
4x - 3y = 1________ ( 2 )
( 1 ) × 3 ____ 9x + 15y = 24 _____ ( 3 )
( 2 ) × 5____ 20x - 15y = 5 _____ ( 4 )
( 3 ) + ( 4 )
[tex]9x + 15y + 20x - 15y = 24 + 5 \\ 9x + 20x + 15y - 15y = 29 \\ 29x = 29 \\ x = \frac{29}{29} \\ x = 1 \\ [/tex]
x = 1 substitute to ( 1 ) ,
[tex]3x + 5y = 8 \\ 3(1) + 5y = 8 \\ 3 + 5y = 8 \\ 5y = 8 - 3 \\ 5y = 5 \\ y = \frac{5}{5} \\ x = 1 \\ [/tex]
b.6p + 4q = 20_______ ( 1 )
5p – 2q = 6 _______ ( 2 )
( 2 ) × 2 ____ 10p - 4q = 12 _______ ( 3 )
( 1 ) + ( 3 )
[tex]6p + 4q + 10p - 4q = 20 + 12 \\ 6p + 10p + 4q - 4q = 32 \\ 16p = 32 \\ p = \frac{32}{16} \\ p = 2 \\ [/tex]
p = 2 substitute to ( 1 ) ,
[tex]6p + 4q = 20 \\ 6(2) + 4q = 20 \\ 12 + 4q = 20 \\ 4q = 20 - 12 \\ 4q = 8 \\ q = \frac{8}{4} \\ q = 2 \\ [/tex]

Answers
Answer:

Step-by-step explanation:
First you need to find the median of the two numbers. The fastest way to do it is to add 9.3 and 9.7 and divide by 2, which will give you 9.5. Since there's going to be two of them working, divide 9.5 by 2, and you get 4.75.
1/9.3 + 1/9.7 = 1/x
