Answer:

40 X 10.75= 430  

10.75/2= 5.375 round up 5.38  

10.75 + 5.38 = 16.13  

16.13 X 10 = 161.30  

430+161.30= 591.3

[tex]\frac{1}{15}[/tex] cup of flour

Step-by-step explanation:

5 rolls = [tex]\frac{1}{3}[/tex] cup

? × 5 = [tex]\frac{1}{3}[/tex]

[tex]\frac{1}{3}[/tex] ÷ 5 = ?

[tex]\frac{1}{3}[/tex] ÷ [tex]\frac{5}{1}[/tex] = [tex]\frac{1}{3}[/tex] × [tex]\frac{1}{5}[/tex] = [tex]\frac{1}{15}[/tex]

Answer:

Tom need to rent the court in order for it to be cheaper more than 15 times.

Step-by-step explanation:

Answer:

Tom needs to rent it atleast 17 times.

Step-by-step explanation:

1) First, write your equations. x in this case equals the # of times you rent the court.

For members: y = 135 + 3x (members)

Non-members: y = 11x (non-members)

From here, there can me many methods that can work. Right now I can only think of one though :/.

So what you can do is plug in numbers and see what happens. I suggest you work with easy numbers when you plug stuff in. Once you find that non-members is greater than the amnt for members have, that's your answer!

a) x = 10

For members: 135 + 3(10) = 165

Non-members: 11(10) = 110

Didn't work. :(

b) x = 20

For members: 135 + 3(20) = 195

Non-members: 11(20) = 220

Aha! We have a valid answer. However, we need to find the minimum number of times Tom needs to rent it.

c) x = 15

For members: 135 + 3(15) = 180

Non-members: 11(15) = 165.

So our answer is between 15 and 20.

If you keep doing this, you'll find that 18 is the minimum number of times tom will have to rent the court. So your answer is anything greater than equal to 17.

x = 17

For members: 135 + 3(17) = 186

Non-members: 11(17) = 187

Sorry I made this tedious, but this is one method. Though I helped you find the answer, I hope someone else can help you find the best method!

Step-by-step explanation:

It is given that the number of bacteria doubles every hour.

Therefore, the number of bacteria after every hour will form a G.P.

with first term (a=30) and common ratio (r=2)

∴a

3

​

=ar

2

=(30)(2)

2

=120

Therefore, the number of bacteria at the end of 2nd hour will be 480.

a

5

​

=ar

4

=(30)(2)

4

=480

and a

n+1

​

=ar

n

=(30)(2)

n

Thus the number of bacteria at the end of nth hour will be (30)(2)

n

Geometric sequence can model the considered situation. The number of bacteria in 18 hours for the considered situation will be 264

There are three parameters which differentiate between which geometric sequence we're talking about.

Suppose the initial term of a geometric sequence is [tex]a[/tex] and the term by which we multiply the previous term to get the next term is [tex]d[/tex]  

Then the sequence would look like

[tex]a, ad, ad^2, ad^3, ad^4,...[/tex] (till the terms to which it is defined)

Thus, the nth term of such sequence would be

[tex]T_n = ad^{n-1}[/tex]

We can model the given situation with the geometric sequence since each previous count is being doubled(multiplied by 2) per 4 hours.

We're given initial number of bacteria = a = 22

Each new element will be denoting number of bacteria after 4 hours from previous count.

So, from 0 to 16 hours, there are four set of 4 hours. Thus, n = 4

Since number of bacteria are doubling, thus, d= 2

We get fourth term  = number of bacteria after 16 hours

[tex]T_n = a(d)^{n-1} = 22 \times (2)^3 = 176[/tex]

Now, in the last 2 hours, assuming that if x -> 2x in 4 hours(which is increment of x), then in 2 hours, only x/2 must be incremented.(assuming linear growth in each 4 hour group).

Thus, after 18 hours, 176 + 176/2 will be the number of bacteria.

Thus, Number of bacteria after 18 hour for the given case = 176 + 88 = 264

Answer:  2744

Step-by-step explanation: 14x14= 196 x14 =2744

Answer:

The answer is 2744.

Step-by-step explanation:

First solve for 14 x 14, which is 196.

Then solve for 196 x 14, which is 2744.

Hence, the answer is 2744.

4(+2)=8+4

1.Distribute

4(+2)=8+4

4+8=8+4

2.Rearrange terms

4+8=8+4

4+8=4+8

3.Subtract 8 from both sides of the equation

4+8=4+8

4+8−8=4+8−8

4.Simplify

4+8−8=4+8−8

4=4+8−8

2.Subtract the numbers

4=4+8−8

4=4

5.Subtract 4 from both sides of the equation

4=4

4−4=4−4

6.Simplify

1.Combine like terms

4−4=4−4

0=4−4

0=0

The Answer is 0=0.

[tex] \frac{1}{5}(25 - 5a) = 4 - a [/tex]

Rearrange terms

[tex] \frac{1}{5}(25 - 5a) = 4 - a \\ \frac{1}{5}( - 5a + 25) = 4 - a \\ [/tex]

2.Combine multiplied terms into a single fraction

[tex] \frac{1}{5}( - 5a + 25) = 4 - a \\ \frac{1( - 5a + 25)}{5} = 4 - a [/tex]

3.Multiply by 1

[tex] \frac{1( - 5a + 25)}{5} = 4 - a \\ \frac{ - 5a + 25}{5} = 4 - a [/tex]

4. Rearrange terms

[tex] \frac{ - 5a + 25}{5} = 4 - a \\ \frac{ - 5a + 25}{5} = - a + 4 [/tex]

5.Add  to both sides of the equation

[tex] \frac{−5+25}{5} = - a + 4 \\ \frac{−5+25}{5} + a= - a + 4 + a [/tex]

6. Simplify

Find common denominator

[tex] \frac{ - 5a + 25}{5} + a = - a + 4 + a \\ \frac{ - 5a + 25}{5} + \frac{5a}{5} = - a + 4 + a [/tex]

2.Combine fractions with common denominator.

[tex] \frac{ - 5a + 25}{5} + \frac{5a}{5} =−+4+ \\ \frac{−5+25 + 5a}{5} = - a + 4 + a [/tex]

3. Combine like terms

[tex] \frac{ - 5a + 25 + 5a}{5} = −+4+ \\ \frac{25}{5} = −+4+[/tex]

4. Cancel terms that are in both the numerator and denominator

[tex] \frac{25}{5} = −+4+ \\ 5 = −+4+[/tex]

5. Combine like terms

5 = - a + 4 + a
