what is 1/2 divided by 74​

Answer:

multiply 2/5 by 4

Step-by-step explanation:

When we divide fractions, we use copy dot flip

2/5 ÷ 1/4

Copy dot flip

2/5 * 4/1

For this case we must find the quotient of the following expression:

[tex]\frac {\frac {2} {5}} {\frac {1} {4}} =[/tex]

Applying double C we have:

[tex]\frac {2 * 4} {5 * 1} = \frac {8} {5}[/tex]

This is equivalent to multiplying the following: [tex]\frac {2} {5} * 4 = \frac {8} {5}[/tex]

Answer:

OPTION A

To solve this question, we must use the cosine rule:

cos(A) = (b^2 + c^2 - a^2)/2bc, where A is the angle you want to find, a is the side opposite that angle, and b and c are the other two sides of the triangle.

Given that we know that a = 6, b = 12, c = 14, we can substitute these values into the formula to get:

cos(A) = (12^2 + 14^2 - 6^2)/2(12)(14)

cos(A) = (144 + 196 - 36)/336

cos(A) = 304/336

cos(A) = 19/21

A = cos-1(19/21)

A = 25° (to the nearest degree)

Answer:

(0,∞)

Step-by-step explanation:

The problems tells us to find the range of the function

f(x)=2*(1/4)^x

after it has been reflected over the y-axis

This means

Answer:

22.34 km²

Step-by-step explanation:

Here we have a circle whose diameter is 5  1/3 km.  As an improper fraction, that's 16/3 km.  Half that, or 8/3 km, is the radius.

The area of a circle is A = πr², where r is the radius.

In this case, the area is A = π(8/3 km)², or (64/9)π km², or 22.34 km² (same as first answer choice).

Answer:

40

Step-by-step explanation:

40=lowest

To find the product of two expressions, we use the distributive property and multiply each term from the first expression with each term from the second expression, then combine the like terms.

The product of[tex](3a + 2)(4a^2 - 2a + 9) is 12a^3 - 6a^2 + 23a + 18.[/tex]

To find the product of two binomials, you can use the distributive property. In this case, you multiply each term in the first binomial, 3a and 2, by each term in the second binomial, 4a^2, -2a, and 9, and then combine like terms.

[tex](3a + 2)(4a^2 - 2a + 9) = 3a * 4a^2 + 3a * (-2a) + 3a * 9 + 2 * 4a^2 + 2 * (-2a) + 2 * 9[/tex]

Now, perform the multiplications:

[tex]12a^3 - 6a^2 + 27a + 8a^2 - 4a + 18[/tex]

Combine like terms:

[tex](12a^3 - 6a^2) + (27a - 4a) + 1812a^3 - 6a^2 + 23a + 18[/tex]

So, the product of[tex](3a + 2)(4a^2 - 2a + 9)[/tex]is indeed[tex]12a^3 - 6a^2 + 23a + 18.[/tex]

Answer:

x = 1

Step-by-step explanation:

ln x + ln x = 0

2ln x = 0

ln x = 0

recall ln x = [tex]log_{e}[/tex]x

so equation becomes

[tex]log_{e}[/tex]x = 0

or [tex]e^{0}[/tex]=x

since anything raised to the power of zero = 1

x = 1

Answer:

x = 1

Step-by-step explanation:

We are to find the solution of the following logarithmic equation:

[tex] ln ( x ) + l n ( x ) = 0 [/tex]

We will add the similar elements to get:

[tex] 2 l n ( x ) = 0 [/tex]

Dividing both sides by 2 and simplify to get:

[tex] \frac { 2 l n ( x ) } { 2 } = \frac { 0 } { 2 } [/tex]

[tex]ln(x)=0[/tex]

Applying the rule [tex]a=log_b(b^a)[/tex] to get:

Answer:

Rebecca has 18 nickels and 27 dimes

Step-by-step explanation:

Let x be the number of nickels Rebecca has, then 45-x is the number of dimes she has.

The total value of Rebecca's coins is $3.60.

1 nickel - 5 cents

x nickels - 5x cents

1 dime - 10 cents

45-x dimes - 10(45-x) cents

Total x nickels and 45-x dimes is 5x+10(45-x) cents that is $3.60=360 cents. So,

5x+10(45-x)=360

5x+450-10x=360

5x-10x=360-450

-5x=-90

5x=90

x=18

45-x=45-18=27

Answer:

B = 58.9

Step-by-step explanation:

We are given that a triangle ABC has two side lengths of 28 ft. and 24 ft. with angle C measuring 91°. We are to find the measure of angle B.

AB = 28 ft

AC = 24 ft

For this, we will use the sine formula:

[tex]\frac{sin B}{24} = \frac{sin91}{28}[/tex]

[tex]sin B = \frac{sin91 \times 24}{28}[/tex]

[tex] sin B = 0 . 8 5 7 [/tex]

[tex] B = sin' 0 . 8 5 7 [/tex]

B = 58.9

Answer:

(x - 8)^2 + (y - 4)^2 = 16.

Step-by-step explanation:

The standard form can be written as:

(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the center and r = the radius.

So here we have a = 8, b = 4 and r = 4.

(x - 8)^2 + (y - 4)^2 = 4^2

(x - 8)^2 + (y - 4)^2 = 16.

Answer:

x = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Using the rules of logarithms

• log x + log y ⇔ log(xy)

• [tex]log_{b}[/tex] = n ⇔ x = [tex]b^{n}[/tex]

Given

ln 2x + ln 2 = 0

ln(2x × 2) = 0

ln 4x = 0

4x = [tex]e^{0}[/tex] = 1 ( divide both sides by 4 )

x = [tex]\frac{1}{4}[/tex]

Answer:

17/20

Step-by-step explanation:

To find the simplest form of 0.85 you need to turn it into a fraction.

To turn it into a fraction you put 85 over 100 since 0.85 is in the hundredths place.

85/100 can be simplified to 17/20 because 85/5 is 17 and 100/5 is 20

Answer:

17/20

Step-by-step explanation:

The simplest form of a number is a fraction. .85 as a fraction is 85/100. Simplifying this into 17/20 puts it into its simplest form.

The scale factor of the dilation is 0.25 ----> given problem

The coordinates of point A(-5,-3) and F(3,1)

step 1

Find the x-coordinate of point A'

The horizontal distance between A and F is equal to

AFx=3-(-5)=8

The horizontal distance after dilation between A'F is equal to

A'F=0.25*8=2

so

the x-coordinate of vertex A' is equal to the x-coordinate of F minus the horizontal distance after dilation A'F

A'x=3-2=1

step 2

Find the y-coordinate of point A'

The vertical distance between A and F is equal to

AFy=1-(-3)=4

The vertical distance after dilation between A'F is equal to

A'Fy=0.25*4=1

so

the y-coordinate of vertex A' is equal to the y-coordinate of F minus the vertical distance after dilation A'F

A'y=1-1=0

therefore

The coordinates of vertex A of the image is (1.0)

option C.

The statement that best describes a square is: A special rectangle that has four sides of equal length. This statement aligns with the definition of a square within the field of geometry, where a square is understood as a type of rectangle with all sides being the same length. Therefore, the correct answer is C. A special rectangle that has four sides of equal length.

A square indeed has four right angles, similar to a rectangle. By extension, it has congruent opposite sides and equal angles, but the defining feature that differentiates a square from other rectangles is the fact that all four sides are of equal length. The concept of rectangles forming squares can be seen in the given reference, implying that equal rectangles can be arranged to form a square - a concept important in understanding how a square is a special case of a rectangle.

For a given trapezium ABCD, measure of angle [tex]D = 52\°[/tex].

" An angle is defined as when two rays meet at a common point known as vertex."
