Answer: $225

Step-by-step explanation:

Each Notebook costs 45 dollars, this can be found by taking the cost of 2 (90$) and dividing it by 2

Now just take the cost per notebook (45) and multiply it by the amount wanted (5) and your total should come out to $225

Answer:

$225 = 5 note books.

45 = 1 note book

Step-by-step explanation:

90/2 = $45 EACH

Unitary method means find 1 part first.

Therefore,

1 part = 45

45 x 5 = 225

$225 = 5 note books.

1.1     Pull out like factors :

  -2x + 2  =   -2 • (x - 1)

2.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

2.2      Solve  :    x-1 = 0

Add  1  to both sides of the equation :

                     x = 1

x = 1

Answer:

51/60

Step-by-step explanation:

First, I'll convert 5 1/10 into an improper fraction to make it easier to work with. I get 51/10. Then, I multiply the two fractions like so:

51/10 * 1/6 = 51/60

You multiply the numerators (the numbers on top) and the denominators (the numbers on the bottom) separately.

So the answer is 51/60.

Points A, B and the lighthouse are related by angles of elevation.

From the complete question (see attachment), we have:

[tex]\mathbf{\angle A = 164 - 90}[/tex]

[tex]\mathbf{\angle A = 74}[/tex]

[tex]\mathbf{\angle B = 270 - 218}[/tex]

[tex]\mathbf{\angle B = 52}[/tex]

[tex]\mathbf{\angle L = 180 - 74 - 52}[/tex]

[tex]\mathbf{\angle L = 54}[/tex]

(a) The distance between the lighthouse and A

This is calculated using the following sine ratio

[tex]\mathbf{\frac{a}{sin A} = \frac{b}{sin B} = \frac{c}{sin C}}[/tex]

So, we have:

[tex]\mathbf{\frac{AL}{sin B} = \frac{100}{sin L}}[/tex]

This gives

[tex]\mathbf{\frac{AL}{sin 52} = \frac{100}{sin 54}}[/tex]

Make AL the subject

[tex]\mathbf{AL = \frac{100}{sin 54} \times sin 52}[/tex]

[tex]\mathbf{AL = 97.4}[/tex]

The distance of the lighthouse from A is 97.4 m

(b) The height of the lighthouse

Considering triangle AHL, we have:

[tex]\mathbf{\angle H = 90 + 27 = 117}[/tex]

[tex]\mathbf{\angle A = 74 - 27 = 47}[/tex]

[tex]\mathbf{AL = 97.4}[/tex]

The height is then calculated using the following sine ratio

[tex]\mathbf{\frac{a}{sin A} = \frac{b}{sin B} = \frac{c}{sin C}}[/tex]

So, we have:

[tex]\mathbf{\frac{AL}{sin H} = \frac{HL}{sin A}}[/tex]

Make HL the subject

[tex]\mathbf{HL = \frac{AL \times sin A}{sin H}}[/tex]

This gives

[tex]\mathbf{HL = \frac{97.4 \times sin 47}{sin 117}}[/tex]

[tex]\mathbf{HL = 79.9}}[/tex]

Hence, the height of the lighthouse is 79.9 m

Answer:

Step-by-step explanation:

To make sure that you are adding 2 odd numbers, the first one is 2x - 1 and 2x + 1

Their sum is 216

Equation

2x - 1 + 2x + 1 = 216

Solution

2x - 1 + 2x + 1 = 216                   Combine like terms on the left

4x = 216                                     Divide by 4

4x/4 = 216/4                               Combine

x = 54

Answer

2x - 1 = 2*54 - 1 = 108 - 1 = 107

2x + 1 = 2*54 + 1 = 108+1 = 109

The two consecutive odd numbers are 107 and 109

Answer:

Step-by-step explanation:The problem is very hard to read.  When using exponents, please add the "^" in front.  For example, is 132 actually 132, or is it 13^2?  The right triangle is not shown, so we really don't know which is the hypotenuse. Also be carefull with spacing.  Making some assumptions, here is how the answer might look:

Both have the correct formula:  a^2 + b^2 = c^2, assuming c is the hypotenuse.

If c is the hypotenuse, then the expression should be:

7^2 + b^2 = 13^2, or

49 + b^2 = 169

I like Sheridan's answer.  So let's continue:

49 + b^2 = 169

b^2 = 169-49

b^2 = 120

b = 10.954 . . .

Yep, I'm on Sheridan's side.  [That is, unless 72 is 72 and not 7^2, etc.]

Answer: x=120 degrees

Step-by-step explanation: Since this triangle is equilateral, each of its angles equals 60 degrees. The line that x is on is equal to 180 degrees, so subtracting 60 from 180 will give you 120 degrees for x.

Answer:

x=180°-60°=120°, bc In an equilateral triangle, the angles are equal and equal to 60°

Answer:

A = $6,464.97

Step-by-step explanation:

Given the principal amount of $5,400, and an interest rate of 3.6% compounded continuously for t = 5 years:

Substitute the given values into the Continuous Compounding Formula:

[tex]A = Pe^{r*t}[/tex]

where:

P = principal = $5,400

e ≈ 2.7183 (irrational number)

r = interest rate = 3.6% or 0.036

t = time in years = 5

[tex]A = Pe^{r*t}[/tex]

[tex]A = 5400e^{(0.036*5)}[/tex]

[tex]A = 5400e^{0.18}[/tex]

A = $6,464.97

Therefore, the amount after compounding continuously for 5 years is $6,464.97.

x = 100

why?

because,

(76 + 124) ÷ 2 = 200 ÷ 2

Answer:

-2 3/5, -9/4, 1.2, 7/4

Step-by-step explanation:

First, unmix the mixed numbers.

-9/4 = -2 1/4.

Which is greater?

1/4 vs. 3/5

Answer: 3/5 So...

-2 3/5 would be the least.

Then there would be -2 1/4

Then, it would be 1.2 because 1.2 is smaller than 7/4.

Therefore, this pattern would be the correct answer...

From Least to greatest=

-2 3/5, -9/4, 1.2, 7/4

Fact family

No, it should be written as

[tex]y = Ce^{-\cos x}[/tex]

Provided that y ≠ 0, both solutions

[tex]y = e^{C-\cos(x)}[/tex]

and

[tex]y = Ce^{-\cos(x)}[/tex]

are correct. The other solution you provided,

[tex]y = C - e^{\cos(x)}[/tex]

is not.

The only difference between the "valid" solutions lies in the particular value of the arbitrary constant C.

Suppose y(0) = Y ≠ 0 is given as an initial condition. Then in the first solution,

[tex]Y = e^{C - \cos(0)} \implies \ln|Y| = C - 1 \implies C = \ln|Y| + 1[/tex]

In the second solution,

[tex]Y = C e^{-\cos(0)} \implies Y = Ce^{-1} \implies C = eY[/tex]

But both solutions are the same, since

[tex]y = e^{\ln|Y| + 1 - \cos(x)} = e^{\ln|Y|} e^1 e^{-\cos(x)} = eY e^{-\cos(x)}[/tex]
