We essentially have x = 180 and a+b+c = x.

So we are just substituting x for a+b+c

Answer:

There are 43 nickels in the piggy bank.

Step-by-step explanation:

Given that:

Number of coins = 91

Worth of coins = $6.95 = 6.95*100 = 695 cents

Let,

x be the number of nickles

y be the number of dimes

According to given statement;

x+y=91     Eqn 1

5x+10y=695     Eqn 2

Multiplying Eqn 1 by 5

5x+5y = 455    Eqn 3

Subtracting Eqn 3 from Eqn 2

(5x+10y)-(5x+5y)=695-455

5x+10y-5x-5y=240

5y = 240

[tex]\frac{5y}{5}=\frac{240}{5}[/tex]

y = 48

Putting y=48 in Eqn 1

x+48=91

x=91-48

x= 43

Hence,

There are 43 nickels in the piggy bank.

A. y- 3 = -12(x - 5)

Step-by-step explanation:

Answer:

68.27%.

Step-by-step explanation:

Here we have [tex]\mu=500,\sigma=100[/tex]

Let X shows the SAT score. z-score for X=400 is

[tex]z=\frac{X-\mu}{\sigma}=\frac{400-500}{100}= -1[/tex]

z-score for X=600 is

[tex]z=\frac{X-\mu}{\sigma}=\frac{600-500}{100}=1[/tex]

So the proportion of SAT scores falls between 400 and 600 is

[tex]P(400<X<600)=P(-1<z<1)=0.6827[/tex]

hence, required percentage is 68.27%.

one can use the same method to find the% for all other cases as

Answer:

  3.65% monthly

Step-by-step explanation:

The same amount is invested for the same period in all accounts, so we only need to determine the effective annual rate in order to compare the accounts.

For compounding annual rate r n times per year, the effective annual rate is ...

  (1 +r/n)^n -1

For the same rate r, larger values of n cause effective rate to be higher. As a consequence, we know that 3.65% compounded quarterly will not have as great a yield as 3.65% compounded monthly. The effective rate for the monthly compounding is ...

  (1 +0.0365/12)^12 -1 = 3.712%

The effective rate for continuous compounding is ...

  e^r -1

For a continuously compounded rate of 3.6%, the effective annual rate is ...

  e^0.036 -1 = 3.666%

This tells us the best yield is in the account bearing 3.65% compounded monthly.

_____

If i is the effective annual rate of interest as computed by the methods above, then the 10-year account balance will be ...

  10000×(1 +i)^10

This is the formula used in the spreadsheet to calculate the balances shown.

Answer:

Step-by-step explanation:

This is a help site, so I'll explain each property and see if you can match them yourself.

Associative property of addition, you can add 3 or more different numbers any which way, the sum will be the same.

Commutative Property of Addition - same as the associative property but with 2 numbers.

Identity Property of Multiplication - Any number multiplied by one is itself

Multiplicative Property of Zero: x * 0 = 0

Associative Property of Multiplication - Same as that of addition, yet with multiplication.

Distributive Property: Factoring Out.

Answer:

The base of the number is 8

Answer:

21 quarters and 11 dimes = 32 coins

Step-by-step explanation:

x + y = 32

0.25x + 0.10y = 6.35 [take the first equation and make it equal to x]

x = 32 - y [now take this equation and plug it in the above]

0.25 (32-y) + 0.10y = 6.35

8 - 0.25y + 0.10y = 6.35

8 - 0.15y = 6.35  [subtract 8 from both sides]

-0.15y = -1.65 [divide by -0.15 to isolate y]

y = 11 so there are 11 dimes

plug it into the first equation: x + 11 = 32; x = 21 so there are 21 quarters

Answer:

1)  [tex]\mathbf{\sqrt{50}= 5\sqrt{2} }[/tex]

2) [tex]\mathbf{\sqrt{28}= 2\sqrt{7} }[/tex]

3) [tex]\mathbf{\sqrt{252}= 6\sqrt{7} }[/tex]

Step-by-step explanation:

We need to simplify the radicals:

1) [tex]\sqrt{50}[/tex]

First we find prime factors of 50

50 = 2 x 5 x 5

Now,

[tex]\sqrt{50}\\=\sqrt{2\times 5\times 5}\\=\sqrt{2\times 5^2}\\ =\sqrt{2} \sqrt{5^2}\\=5\sqrt{2}[/tex]

So, [tex]\mathbf{\sqrt{50}= 5\sqrt{2} }[/tex]

2) [tex]\sqrt{28}[/tex]

First we find prime factors of 28

28 = 2 x 2 x 7

Now,

[tex]\sqrt{28}\\=\sqrt{2\times 2\times 7}\\=\sqrt{2^2\times 7}\\ =\sqrt{2^2} \sqrt{7}\\=2\sqrt{7}[/tex]

So, [tex]\mathbf{\sqrt{28}= 2\sqrt{7} }[/tex]

3) [tex]\sqrt{252}[/tex]

First we find prime factors of 252

50 = 2 x 2 x 3 x 3 x 7

Now,

[tex]\sqrt{252}\\=\sqrt{2\times 2\times 3\times 3 \times7}\\=\sqrt{2^2\times 3^2 \times7}\\ =\sqrt{2^2} \sqrt{3^2}\sqrt{7} \\=2\times 3\sqrt{7}\\=6\sqrt{7}[/tex]

So, [tex]\mathbf{\sqrt{252}= 6\sqrt{7} }[/tex]

Answer:

An equation in point-slope form for the line will be:

[tex]y - (-3) = 8 (x - (-4))[/tex]

Please check the attached line graph also.

Step-by-step explanation:

Given

The point (-4, -3)

The slope m = 8

To determine

Write an equation in point slope form for the line.

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

In our case,

substituting the values m = 8 and the point (-4, -3)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - (-3) = 8 (x - (-4))[/tex]

Therefore, an equation in point-slope form for the line will be:

[tex]y - (-3) = 8 (x - (-4))[/tex]

Please check the attached line graph also.

Answer:

The Buzz can travel 733.33 feet per second.

Step-by-step explanation:

An hour has 60 minutes, each of which has 60 seconds. So one hour has 60*60 = 3600 seconds.

The airplane can fly 500 miles per hour. Each mile has 5280 feet. So the plane can fly 500*5280 = 2640000 feet in one hour.

Per second, we have:

[tex]\frac{2640000}{3600} = 733.33[/tex]

The Buzz can travel 733.33 feet per second.
