3 0

Answer:

  • x = 11

Step-by-step explanation:

  • JM = JK + KL + LM

<u>Substitute the values and solve for x:</u>

  • 23 = 9 + 2x - 18 + x - 1
  • 23 = 3x - 10
  • 3x = 23 + 10
  • 3x = 33
  • x = 33/3
  • x = 11

One link in a chain was made from a cylinder that has a radius of 2.5 cm and a height of 22 cm. How much plastic coating would b
bulgar [2K]

Answer:

c) 345.4 cm²

The  plastic coating would be needed to coat the surface of the chain link

                      = 345.4 cm²  

Step-by-step explanation:

<em>Given radius of the cylinder 'r' = 2.5 cm</em>

<em>Given Height of the cylinder 'h' = 22 cm</em>

<em>Area of the curved surface =  2 π r h </em>

<em>The plastic coating would be needed to coat the surface of the chain link</em>

<em>                   A =  2 π r h </em>

<em>                  A =  2 × 3.14 ×2.5×22 </em>

<em>                 A   = 345.4 cm²</em>

<u><em>Conclusion</em></u><em>:-</em>

<em>The  plastic coating would be needed to coat the surface of the chain link</em>

<em>                       = 345.4 cm²</em>

Marc mixes blue and yellow paint to make his favorite shade of green, which he'll use to paint his house. He has 14 cans of blue
exis [7]

The ratio of blue paint to yellow paint is 2 : 3.

The total number of blue paint he used on the first and second day is 10.

The number of yellow paint he used on the first and second day is 15.

On the third day, the highest number of can of blue paint he can use is 2

On the third day, the highest number of can of yellow paint he can use is 3.

<h3>What is the highest number of blue and yellow paint he can use?</h3>

The ratio of blue paint to yellow paint can be determined by determining the simplest form of the paints used: 4 : 6 = 2: 3

Total blue paint cans used on the first and second day = 4 + 6 = 10

Blue paint cans remaining = 14 - 10 = 4

Total yellow paint cans used on the first and second day = 6 + 9 = 15 cans

Yellow paint cans remaining = 20 - 15 = 5 cans

At the beginning of the year, the number of books owned by a library was 10,000. Since then, it has grown by 1% each month.
aleksklad [387]

Answer:

y = 10(1.01)^60

Step-by-step explanation:

The general equation of exponential growth is

y = ab^x

b has to do with the rate of growth.

b = 1 + r, so in this case, b = 1 + 1% = 1 + 0.01 = 1.01.

Now we have

y = a(1.01)^x

a is the initial value, so now we have

y = 10000(1.01)^x

where y is the number of books after x months

Since you need the number of books after 5 years, we must convert 5 years into months.

5 years * (12 months)/year = 60 months

The problem wants the expression in thousands of books, so we divide the initial value by 1000.

Answer: y = 10(1.01)^60

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. Note that PEMDAS =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

& is the order of operation.

Also note, that you are solving for x, in all instances.

1) x + c = d

Note the equal sign, subtract c from both sides:

x + c (-c) = d (-c)

x = d - c

2)  x - p = g

Note the equal sign, add p to both sides:

x - p (+p) = g (+p)

x = g + p

3) FX = S

Note the equal sign, divide F from both sides:

(FX)/F = (S)/F

X = S/F

4) 3x - q = p

Note the equal sign, first, add q to both sides:

3x - q (+q) = p (+q)

3x = p + q

Next, divide 3 from both sides. Note that when you divide 3 from the right side, you are dividing from all terms:

(3x)/3 = (p + q)/3

x = (p + q)/3

5) cx - d = 4

Note the equal sign, first, add d to both sides:

cx - d (+d) = 4 (+d)

cx = 4 + d

Next, divide c from both sides.

(cx)/c = (4 + d)/c

x = (d + 4)/c

6) FX - S = M

Isolate the variable, x. First, add S to both sides:

FX - S (+S) = M (+S)

FX = M + S

Next, divide F from both sides:

(FX)/F = (M + S)/F

X = (M + S)/F
