Answer:

5+8 =45

Step-by-step explanation:

Given the pattern

  • 1+4=5
  • 2+5=12
  • 3+6=21

Let us represent it with the form: a+b=c

The key is: a+(b X a) =c

Let us verify

  • In 1+4 =5, a=1,b=4, a+(b X a)=1+(4X1)=1+4=5=c
  • In 2+5=12, a=2, b=5, a+(b X a)=2+(5X2)=2+10=12=c
  • In 3+6=21, a=3, b=6, a+(b X a)=3+(6X3)=3+18=21=c

Therefore:

In 5+8, a=5. b=8

a+(b X a) = 5 +(8 X 5) =5+40 =45

5+8 =45

what is the volume of a cylinder with height of 9 inches and the the radius is 1 inch. round to the nearest cubic inch
poizon [28]

Answer:

Step-by-step explanation:

Volume of cylinder can be calculated by using the formula V= pir^2h

Where r is radius of cylinder and h is the height.

A cylinder with radius 1 inch and height of 9 inch is given.

r=1,h=1,π=3.14.

Substituting the given values :

V=πr2h=π·12·9≈28.27433

Volume of cylinder rounded to nearest tenth is 28.27 cubic inches .

Use three different values of n to demonstrate that 2n + 3n is equivalent to 5n.
GarryVolchara [31]
 n can be 0 so 2(0) +3(0) = 0 now lets go up by one so 2(1) +3(1)= 5 now we will go up another number so lets go for 2(2)= 10 so  we figured out that 2(1) +3(1) is  5 so n equals 1

Alex has a bag of marbles. Each marble is red or blue, and the ratio of red to blue marbles is 3 : 5. After Alex adds 10 red mar
Otrada [13]

Solving a system of equations we will see that there are 150 blue marbles in the bag

<h3>How many blue marbles are in Alex’s bag?</h3>

We know that initially, the ratio of red to blue marbles is 3:5

This means that if there are 8*n marbles in the bag, there are:

  • 3*n red marbles.
  • 5*n blue marbles.

Now, when he adds 10 red marbles, the new ratio is 2:3, this means that if now there are 5*m marbles, we have:

  • 2*m red marbles
  • 3*m blue marbles.

Where we will have two relations, so we have a system of equations:

3*n + 10 = 2*m

8*n + 10 = 5*m

With these two we can find the value of n and m.

To do that, we isolate m in the first equation:

m = (3*n + 10)/2

Now we can replace that in the other equation to get:

8*n + 10 = 5* (3*n + 10)/2

Now we can solve this for n:

2*(8*n + 10) = 5*(3n + 10)

16n + 20 = 15n + 50

n = 50 - 20 = 30

n = 30

And the number of blue marbles is:

5*n = 5*30 = 150

There are 150 blue marbles.
