Write the number 0.00004 in scientific notation.

Answer:

For the first one it is 5x+2

Step-by-step explanation:

(9x+5) - (4x+3) = ?

First you minus the x's together so,

9x-4x which would equal 5x

then you minus the 5 and 3 together so,

5-3 which would equal 2

then you put the 5x and the 2 together and you get

5x+2 :-)

Answer:

Step-by-step explanation:

To prove that EFGH is a parallelogram, the missing reasons are:

1. Alternate interior angles theorem

2. Reflexive property

3. SAS

4. CPCTC

5. Both pairs of quadrilateral EFGH are congruent, hence, EFGH is a parallelogram.

A parallelogram is a quadrilateral that has: two pairs of opposite sides that are parallel and congruent

To prove that EFGH is a parallelogram, we have the following proof which consists of the reasons that jsutifes each given statement:

1. ∠FGE and ∠HEG are alternate interior angles, therefore, ∠FGE ≅ ∠HEG based on the alternate interior angles theorem.

2. EG ≅ EG based on the reflexive property of congruence.

3. ΔFGE and ΔHEG have:

two pairs of corresponding congruent sides - EG ≅ EG, and FG ≅ EH

one pair of included congruent angles - ∠FGE ≅ ∠HEG

Therefore, ΔFGE ≅ ΔHEG by SAS.

4. Since ΔFGE ≅ ΔHEG, therefore, FE ≅ HG by CPCTC.

5. In conclusion, since both pairs of quadrilateral EFGH are congruent, then EFGH is a parallelogram.

Answer:

The initial value is;

y = 16

Step-by-step explanation:

Here, we want to get the initial value of y

Generally, for an exponential function,

we have the form as;

y = a•b^x

where the initial value is the value we have when x = 0

Looking at the given function, substituting x = 0

We have the function as;

y = 16(0.75)^0

y = 16 * 1

y = 16

So the initial value is 16

Answer:

no one eats oreos fatty

Step-by-step explanation:

The number of cookies that came inside the box is 15.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, A serving size of Oreo cookies is 3 cookies, which is  20% of a box of cookies.

Let 'x' be the number of cookies the box has.

Therefore 20% of 'x' is 3 which is,

(20/100)×x = 3.

0.2x = 3.

x = 3/0.2.

x = 15.

So, There are 25 cookies in the box.

Answer:The population of a town is increasing at a rate of 6.2% per year. The city council believes they will have to add another elementary …

Step-by-step explanation:

Long until a new elementary school needed is 9.6.

Given:

Interest rate, r = 6.2% or 0.062

Amount, A = 100000

Principle, P = 76000

As we know,

[tex]$\Rightarrow A=P\left(1+\frac{r}{100}\right)^{n}$$[/tex]

On substituting the values, we get

[tex]$&\Rightarrow 100000=76000\left(1+\frac{6.2}{100}\right)^{n} \\[/tex]

[tex]$&\Rightarrow(1+0.062)^{n}=\frac{100}{76}[/tex]

On taking log both sides, we get

[tex]$&\Rightarrow n \log _{c}(1.062)=\log _{c}\left(\frac{100}{76}\right) \\[/tex]

[tex]$&\Rightarrow \quad n=\frac{\ln \left(\frac{100}{76}\right)}{\ln (1.062)}[/tex]

By putting the values of log, we get

[tex]$\Rightarrow \quad=4.5622$[/tex]

[tex]$\Rightarrow \quad=4.6[/tex]

Therefore, the correct answer is 4.6.

Answer:

Aiden would have $67 more than Autumn.

Step-by-step explanation:

Aiden compounded continuously, which uses the formula: [tex]P(t)=P_oe^r^t[/tex]

Plugging in what we know about Aiden's investment: [tex]P(11)=98000e^0^.^0^2^*^1^1[/tex]

That gives us: 122115.5196

Autumn invested using regular compound interest, which has the formula: [tex]A=P(1+\frac{r}{t})^n^t[/tex]

Since Autumn's investment is getting compounded quarterly, n=4 because it gets compounded 4 times a year.

Plug in Autumn's investment: [tex]A=98000(1+\frac{0.02}{4})^4^*^1^1[/tex]

That gives us: 122048.5974

Now just subtract the two and round to the nearest dollar:

[tex]122115.5196-122048.5974=66.92215187[/tex]

OR

$67. Aiden would have $67 more than Autumn after 11 years.

Hey there!

In (a) part we can see that a person delivers approximately 120 newspapers in 3 hours. Kate will deliver 30 × 3 = 90 newspapers. So, (a) part is the answer.

In (b) part, a person delivers 40 newspapers in 4 hours, Kate delivers 30 × 4 = 120 newspapers. So, Kate is faster, (b) option cancelled.

In (c) a person delivers 110 newspapers in 4.5 hours. Kate will deliver 30 × 4.5 = 135 papers, that's again greater. Option (c) cancelled.

Option (d), we can easily cancel it out. But I'm showing the work; a person delivers 20 newspapers in 4 hours, Kate delivers 30 × 4 = 120 newspapers, much faster than the person.

Hence option (a) is the answer.

Answer:

Your answer is 8.06.

Step-by-step explanation:

Since you're finding the hypotenuse of the triangle through Pythagorean theorem, you need to use the formula:

a² + b² = c²

Here, you have to remember that x is the same as c in the formula. c is the hypotenuse and x.

a is going to be your smallest leg, so in this case a = 4.

b is going to be your longest leg, so it is b = 7.

Now, you don't know what c yet is so you simply write it as:

4² + 7² = c²

Do the exponents.

16 + 49 = c²

Add.

65 = c²

Now you need to get the exponent away from the c. To do that, all you have to do is square root both sides.

√65 = √c2

Once you do that, you have your answer!

8.0622577483 = c

Now just simplify and you're done :)

<2 + 57 + 33 = 180

<2 + 90 = 180

<2 = 90

Hello there!

Here, we want to use the Pythagorean Theorem: [tex]a^{2} + b^{2} = c^{2}[/tex].

For problem number 7, we plug 6 and 8 in for a and b. Like this:

[tex]6^{2} + 8^{2} = c^{2}[/tex]

Now we solve. [tex]6^{2}[/tex] is 36. [tex]8^{2}[/tex] is 64.

64 + 36 = 100

Then, we take the square root of 100 to get c.

[tex]\sqrt{100} = 10[/tex]

(There's something special about this triangle. If you want I'll tell you about it in the comments.)

For problem number 8, we do the same exact thing.

[tex]4^{2} + 12^{2} = c^{2}[/tex]

[tex]4^{2} = 16[/tex]  and  [tex]12^{2} = 144[/tex]

[tex]144 + 16 = 160[/tex]

[tex]\sqrt{160} = 8\sqrt{10}[/tex]

Answer:

$448.76

$73.76

Step-by-step explanation:

We are to calculate the future value with monthly compounding

The formula for calculating future value:

FV = P (1 + r/m)^mn

FV = Future value  

P = Present value  

R = interest rate

m = number of compounding

N = number of years  

$375 x ( 1 + 0.06/12)^12 x 3

$375 x (1.005)^36 = $448.76

Interest earned = future value - amount saved

$448.76 -  $375  = $73.76
