Answer:

The answer is ⇒ x = 0.73244

Step-by-step explanation:

∵ 90^x = 27 ⇒ insert log in both sides

∴ [tex]log(90)^{x}=log(27)[/tex]

∵ 90 = 9 × 10 , 27 = 3³

∵ log(a)^b = b log(a)

∴ log(9 × 10)^x = x log(9 × 10)

∴ [tex]xlog(9*10)=log(3^{3})[/tex]

∵ log(a × b) = log(a) + log(b)⇒log(9 × 10) = log(9) + log(10)

∴ [tex]x[log(9)+log(10)]=3log(3)[/tex]

∵ log(10) = 1 , 9 = 3²

∴ [tex]x[log(3)^{2}+1]=3log(3)[/tex]

∴ [tex]x[2log(3)+1] = 3log(3)[/tex]

∴ x = (3log3)/[2log(3)+1]

∴ x = 0.73244

ANSWER

[tex]x \approx0.732[/tex]

EXPLANATION

The given exponential equation is

[tex] {90}^{x} = 27[/tex]

We take natural log of both sides

[tex] ln( {90}^{x} ) = ln(27) [/tex]

Recall and the following property of logarithms.

[tex] ln( {a}^{n} ) = n \: ln(a) [/tex]

This implies that;

[tex]x ln(90) = ln(27) [/tex]

Solve for x.

[tex]x = \frac{ ln(27) }{ ln(90) } [/tex]

[tex]x \approx0.732[/tex]

Answer:

  A ≈ 56.1°

Step-by-step explanation:

By the law of sines, ...

  sin(A)/a = sin(C)/c

  sin(A) = (a/c)·sin(C)

  A = arcsin((a/c)·sin(C)) = arcsin(5/6·sin(95°)) ≈ 56.1°

Answer:

The perimeter of rectangle is [tex]18\ cm[/tex]

Step-by-step explanation:

Let

x-----> the length of the rectangle

y----> the width of the rectangle

we know that

[tex]x=y+5[/tex] ----> equation A

[tex]120=xy+2x^{2}+2y^{2}[/tex] ---> equation B (area of the constructed figure)

substitute the equation A in equation B

[tex]120=(y+5)y+2(y+5)^{2}+2y^{2}[/tex]

[tex]120=y^{2}+5y+2(y^{2}+10y+25)+2y^{2}\\ 120=y^{2}+5y+2y^{2}+20y+50+2y^{2}\\120=5y^{2}+25y+50\\5y^{2}+25y-70=0[/tex]

using a graphing tool -----> solve the quadratic equation

see the attached figure

The solution is

[tex]y=2\ cm[/tex]

Find the value of x

[tex]x=y+5[/tex] ----> [tex]x=2+5=7\ cm[/tex]

Find the perimeter of rectangle

[tex]P=2(x+y)=2(7+2)=18\ cm[/tex]

Answer:

(3700)(1+.059/12)^4(1+.172/12)^8 is the corect answer -Apex

Step-by-step explanation:

Answer:

Option C is correct.

Step-by-step explanation:

Felipe transferred a balance of $3700 to a new credit.

The card had an introductory offer of 5.9% APR for the first 4 months and after that 17.2 % APR.

The card compounds interest monthly, that gives n = 12

So, the equation that represents Felipe's balance at the end of the year will be:

[tex]p(1+\frac{r}{n})^{a}\times (1+\frac{r}{n})^{b}[/tex]

Here a is the introductory rate number of months that is 4

And b is the rest of the standard months that is 8

So, the expression becomes:

[tex]3700(1+\frac{0.059}{12})^{4}\times (1+\frac{0.172}{12})^{8}[/tex]

Answer:

A

The trigonometric ratios for a right triangle are sine, cosine, and tangent, which relate the sides of the triangle.

The trigonometric ratios for a right triangle are sine, cosine, and tangent. Each ratio is defined in terms of the sides of the triangle.

The sine (sin) ratio is defined as the ratio of the opposite side to the hypotenuse. It is calculated as sin(A) = y/h, where y is the length of the opposite side and h is the length of the hypotenuse.

The cosine (cos) ratio is defined as the ratio of the adjacent side to the hypotenuse. It is calculated as cos(A) = x/h, where x is the length of the adjacent side and h is the length of the hypotenuse.

The tangent (tan) ratio is defined as the ratio of the opposite side to the adjacent side. It is calculated as tan(A) = y/x, where y is the length of the opposite side and x is the length of the adjacent side.

The equivalent expressions are:

(3x²  - 7x + 14) + (5x² + 4x - 6) = B. 8x² - 3x + 8

(2x²  - 5x - 3) + (-10x² + 2x + 7) = A. -8x² - 3x + 4

(12x²  - 2x - 13) + (-4x² + 5x + 9) = C. 8x² + 3x - 4

We have,

Expression:

(3x²  - 7x + 14) + (5x² + 4x - 6)

Combine like terms.

3x² - 7x + 14 + 5x² + 4x - 6

8x² - 3x + 8

Expression:

(2x²  - 5x - 3) + (-10x² + 2x + 7)

Combine like terms.

2x² - 5x - 3 - 10x² + 2x + 7

-8x² - 3x + 4

Expression:

(12x²  - 2x - 13) + (-4x² + 5x + 9)

Combine like terms.

12x² - 4x² - 2x + 5x - 13 + 9

8x² + 3x - 4

Thus,

(3x²  - 7x + 14) + (5x² + 4x - 6) = B. 8x² - 3x + 8

(2x²  - 5x - 3) + (-10x² + 2x + 7) = A. -8x² - 3x + 4

(12x²  - 2x - 13) + (-4x² + 5x + 9) = C. 8x² + 3x - 4

Question

Answer:

Step-by-step explanation:

We could answer this either by checking each listed expression to see whether it is a factor of 9r^2-4r+1, or

We could take the coefficients of 9r^2-4r+1, determine the quantity b²-4ac (called the 'discriminant') and draw a conclusion based upon whether the discriminant is -, + or 0.

Let's use the 2nd approach.

Here, a = 9, b = -4 and c = 1.

Then the discriminant is b²2 - 4ac, or (-4)² - 4(9)(1), or 16 - 36.

Since 16 - 36 is negative, we conclude that this 9r^2 - 4r + 1 has NO REAL FACTORS.

Answer:

The length of each side of the cube is [tex]\frac{1}{8}\ m[/tex]

Step-by-step explanation:

we know that

The volume of a cube is equal to

[tex]V=LWH[/tex]

but remember that in a cube

Length, width and height have the same value

so

Let

b-----> the length side of the cube

[tex]L=W=H=b[/tex]

substitute in the formula

[tex]V=(b)(b)(b)=b^{3}[/tex]

In this problem we have

[tex]V=\frac{1}{512}\ m^{3}[/tex]

substitute and solve for b

[tex]b^{3}=\frac{1}{512}[/tex]

[tex]b=\sqrt[3]{\frac{1}{512}}\\ \\b=\frac{1}{8}\ m[/tex]

therefore

The length of each side of the cube is [tex]\frac{1}{8}\ m[/tex]

Answer:

The area would be 170 cubic inches.

Step-by-step explanation:

To find the area, use the area of a trapezoid formula.

A = (a + b)/2*h

Now input the values

A = (18 + 22)/2 * 8.5

A = 40/2 * 8.5

A = 20 * 8.5

A = 170

Answer:

18/90 or you can say 18 over 90.

Step-by-step explanation:

So we have 18 out of the total of 90 photos.

So we know automatically the fraction is 18/90, we have 18 out of the rest of the 90 photos.  

The fraction of photos in the album that are black and white is calculated by dividing the number of black and white photos (18) by the total number of photos (90) which results in a fraction of 0.2 or 1/5.

To find what fraction of the photos are black and white, you'll start by considering all of the photos in the album. This is your total and it's 90 photos. Then, focus on the specific type of photos you're interested in, which are the black and white ones. There are 18 black and white photos. So to find the fraction of photos that are black and white, you would divide the number of black and white photos (18) by the total number of photos (90). This calculation would look something like this: 18 ÷ 90 = 0.2

So, the fraction of black-and-white photographs is 0.2 or, expressed as a common fraction, 1/5. This means that out of every 5 photos in the album, 1 of them is black and white.

Answer:

The length is 65 cm and the width is 12 cm

Step-by-step explanation:

A = lw = 780

P = 2 (l+w) = 154

The length is 5 more than 5 times the width

l=5w+5

P = 2 (l+w) = 154

Divide each side by 2

2 /2 (l+w) = 154/2

l+w = 77

Substituting l = 5w+5

5w+5 +w = 77

6w+5 = 77

Subtract 5 from each side

6w +5-5 = 77-5

6w = 72

Divide each side by 6

6w/6 = 72/6

w = 12

Now lets find l

l = 5w+5

l = 5(12)+5

l = 60+5

l = 65

Step-by-step explanation: The first piece of information that you need to know is that the product is the answer when two numbers are multiplied. Therefore, you need to multiply the two sets of numbers, and then subtract.

The formula will be:

(5 x 2) - (5 x 1)=

First, do what is inside the parentheses:

10 - 5=

And solve...

5

The expression for the calculation the difference of the products 5 and 2 and 5 and 1 is (5 x 2) - (5 x 1).

Addition (Finding the Sum; '+') Subtraction (Finding the difference; '-') Multiplication (Finding the product; '×' ) Division (Finding the quotient; '÷')

The first thing you should be aware of is that the result of multiplying two integers is the product.

The two sets of numbers must therefore be multiplied before being subtracted.

The Expression will be:

(5 x 2) - (5 x 1)

First, work on the brackets separately

(5 x 2) = 10

(5 x 1)= 5

So, (5 x 2) - (5 x 1)

one inch is 5 feet so for every foot you would x 5

15x5=75

12x5=60

The actual dimensions of Jamal's property are 75 feet long and 60 feet wide.

If Jamal's scale drawing is 15 inches long and 12 inches wide, and one inch on the drawing represents 5 feet in real life, we can calculate the actual dimensions of the property.

Length of the property:

15 inches on the drawing represents 15 * 5 = 75 feet in real life.

Width of the property:

12 inches on the drawing represents 12 * 5 = 60 feet in real life.

Therefore, the actual dimensions of Jamal's property are 75 feet long and 60 feet wide.
