Thirty-six members of the middle school choir, which represents 30%, participated in the regional contents. How many total students are in the choir?

Answers

Answer:

120

Step-by-step explanation:

Given data

36 members are equivalent to 30%

Let the total number of students  be x

Hence

30% of x= 36

30/100*x= 36

0.3x= 36

divide both sides by 0.3

x= 36/0.3

x= 120 students

Hence the total number of students is 120

(vii) log32 8=m
Again please

Answers

Answer:

log_(32)8= 3/5

Step-by-step explanation:

Log_(32)8 = m

write is as

32^m=8

(2^5)^m = 2^3

2^5m = 2^3

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

5m = 3

divide 5 on both sides to remove it from m

m= 3/5

Hope this helps!

The value of m is [tex]\frac{3}{5}[/tex].

What is logarithm?

'Logarithm is the exponent or power to which a base must be raised to yield a given number.'

According to the given problem,

⇒ [tex]log_{32}8[/tex] = m

⇒ m = [tex]log_{32}8[/tex]

⇒ m = [tex]\frac{log 8 }{log32}[/tex]

⇒ m = [tex]\frac{log(2)^{3} }{log(2)^{5} }[/tex]

⇒ m = [tex]\frac{3log2}{5log2}[/tex]

⇒ m = [tex]\frac{3}{5}[/tex]  

Hence, we can conclude, the value of m is [tex]\frac{3}{5}[/tex].

Answer:
1). Increases
2). Slope = 4
3). Slope = -1
4). y = 4 when x = 5
Step-by-step explanation:
1). Initially, as x increases, y also increases. (Linear growth has been shown in the graph initially).
2). Afterward, the slope of the graph of the function is equal to 4 for all x between x = 3 and x = 5.
[Slope of the line passing through two points (3, 0) and (5, 4)

4). The greatest value of y is y = 4, and it occurs when x = 5. (From the given graph)

A water tank holds 944 gallons but is leaking at a rate of 5 gallons per week. A second water tank holds 1,180 gallons but is leaking at a rate of 9 gallons per week. After how many weeks will the amount of water in the two tanks be the same?

Answers

Answer:

59

Step-by-step explanation:

The equation is

944 - 5x = 1180 - 9x

Notice what is being said. You start with 944 gallons and take off 5 per week

You also start with 1180 gallons and take on 9 per week.

You want to know when the two are equal. The second tank is larger, but it leaks more. That's what's going to bring about equality.

Add 9x to both sides

944 - 5x + 9x = 1180

944 + 4x = 1180                

Subtract 944 from both sides.

4x = 1180 - 944

4x = 236      

Divide by 4

x = 236/4

x = 59 weeks

The mean of six numbers is 184.2. The mean of five of the numbers is 178. What is the sixth number?

Answers

Answer:

I'm sorry I'm not very good at math, sorry I couldn't help

Answer: 215.2

Step-by-step explanation:

Since the mean of six numbers is 184.2, this means that their total sum will be:

= 184.2 × 6

= 1105.2

Since the mean of five of the numbers is 178, their total sum will be:

= 178 × 5

= 890

Therefore, the sixth number will be:

= 1105.2 - 890

= 215.2

The sixth number is 215.2

The school store sells markers for $0.35 each and pencils for $0.15
each. Anthony spent $2.80 to buy a total of 12 markers and pencils. How
many markers did Anthony buy?
PLEASE HELP !

Answers

Answer:

x = 5 pens

y = 7 pencils

Step-by-step explanation:

let

x = the number of pens

y = the number of pencils

Anthony spent $2.80 to buy a total of 12 pens and pencils

0.35x + 0.15y = 2.80

x + y = 12

by solving the system of equations

0.35x + 0.15y = 2.80

x + y = 12

we find

x = 5 pens

y = 7 pencils

5. What is the range of the function y = 2x – 4?

Answers

Answer:

The domain is how far left and right it goes on a graph, and the range is how far up and down it goes on a graph. Because this equation is linear (if you graphed it, it would be in a straight line), both the domain and range are infinity, because it keeps going up and to the right, the larger X gets, and smaller and to the left, the more negative X gets.

graph is linear:

y=2x-4

solve for x=o

y=2x0-4       Eliminate 0

y=-4             solved for y

solve for y=0

0=2x-4          add 4

+4      +4

4=2x             divide by 2

/2    /2

4/2 =x

2=x               solved for x

calculate the slope

Step-by-step explanation:

The perimeter is the measurement around an object.

So first you multiply the 20 and the 10 by 2.

20 * 2 = 40

10 * 2 = 20

Then, add then up!

40 + 20 = 60

Answer: 60

Step-by-step explanation:

10+10= 20 (both sides)

20+20=40 (other sides)

40+20=60 (total sides)

−3x − 5 = 16

−4(y − 2) = 12

Answers

Answer:

Step-by-step explanation:

First equation:  −3x − 5 = 16

 Combine the constants:

 -3x = 21

  Solve for x using division:  x = 21/(-3)   or  x = -7

Second equation:  −4(y − 2) = 12

 Reduce this by dividing both sides by -4:  y - 2 = -3

 Add 2 to both sides, to isolate y:  y = -1
