Hi. Here's the work.

First turn everything into an improper fraction.

[tex]1 \frac{1}{2}[/tex] ÷ [tex]4 \frac{1}{2} * 1 \frac{1}{3}[/tex] = [tex]\frac{3}{2}[/tex] ÷ [tex]\frac{9}{2} * \frac{4}{3}[/tex]

To divide fractions we multiply by the flipped version of the fraction, or the reciprocal.

[tex]\frac{3}{2}[/tex] ÷ [tex]\frac{9}{2} * \frac{4}{3}[/tex] = [tex]\frac{3}{2} *\frac{2}{9} *\frac{4}{3}[/tex]

Now we just multiply the fractions!

[tex]\frac{3 * 2 * 4}{2 * 9 * 3}[/tex] = [tex]\frac{4}{9}[/tex]

The answer is therefore 4/9. Please mark brainliest if possible and i hope you get a good grade on your homework. ;)

Answer:

  x = 18

  m = 21.2

  p = 31.8

Step-by-step explanation:

The ratio of the left-side length to the bottom-side length is the same for both triangles:

  x/11.2 = (x +27)/28

  28x = 11.2(x +27) = 11.2x +302.4 . . . . . multiply by 11.2·28

  16.8x = 302.4 . . . . . . . subtract 11.2x

  x = 18 . . . . . . . . . . . . divide by 16.8

__

The length of m can be found using the Pythagorean theorem. The sum of the squares of the legs is the square of the hypotenuse.

  x^2 +11.2^2 = m^2

  m = √(324 +125.44) = √449.44 = 21.2

__

The length of p can also be found using the Pythagorean theorem. We prefer the proportion ...

  p/27 = m/x

  p = 27(21.2/18) = 31.8

The lengths of the unknown sides in the figure are ...

  x = 18

  m = 21.2

  p = 31.8

Step 1: Flip the inequality.

Step 2: Add 16 to both sides.

Therefore, a > -5.

Answer:

a > -5

Step-by-step explanation:

-21-(a-16)<0

Pull out like factors :

-5 - a = -1 • (a + 5)

Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

a+5 > 0

Subtract 5 from both sides

a > -5

It should be noted that a quadratic function simply refers to a function that is in the form of f(x) = ax² + bx + c.

It should be noted that the examples of quadratic functions will be throwing a ball, hitting a golf ball, driving from a platform, etc.

Answer:

Step-by-step explanation:

3=x^2+4x+1

x^2 + 4x + 4 = 0

Discriminant = 4^2 - 4*1*4 = 0

There is one real root (multiplicity 2).

The quadratic equation is x² + 4x + 4 = 0 and the number of solution is 1

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

-3 = x² + 4x + 1

Adding 3 on both sides , we get

x² + 4x + 4 = 0

Now , ( b² - 4ac ) is the discriminant

So , 16 - 4 ( 4 ) = 0

0 = 0

when discriminant is zero we get just one real solution

Hence , the quadratic equation is solved

Answer:

the rate growed so they are more rapes now than the past decade

The number of reported rapes today is more since the percentage has increased.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The number of reported rapes in their jurisdiction increased by 100% over the past decade.

Number of rapes in the last decade = N

Now,

The number of rapes now.

= 200% of N

This means,

The number of rapes is more or increased.

Thus,

The number of reported rapes today is more.

Logarithmic functions and exponential functions are inverse and opposite of one another

The logarithmic function is [tex]y = \log_2(x)[/tex], and the length at 8 pascals is 3 units

The exponential function is given as:

[tex]f(x) = 2^x[/tex]

Express f(x) as y

[tex]y = 2^x[/tex]

Swap the positions of x and y

[tex]x = 2^y[/tex]

Take the logarithm of both sides

[tex]\log(x) = \log(2^y)[/tex]

Apply the rule of logarithm

[tex]\log(x) = y\log(2)[/tex]

Divide both sides by log(2)

[tex]y = \frac{\log(x)}{\log(2)}[/tex]

Apply the change of base rule of logarithm

[tex]y = \log_2(x)[/tex]

When the strength is 8 pascals, we have:

[tex]y = \log_2(8)[/tex]

Express 8 as 2^3

[tex]y = \log_2(2^3)[/tex]

So, we have:

[tex]y =3 \log_2(2)[/tex]

Evaluate log 2 base 2

[tex]y =3[/tex]

Hence, the logarithmic function is [tex]y = \log_2(x)[/tex], and the length at 8 pascals is 3 units

Answer:

175%

Step-by-step explanation:

98 of 56 can be written as: 98/56

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

98/56 × 100/100 = (98 × 100/56) × 1/100 = 175/100

Therefore, the answer is 175%

If you are using a calculator, simply enter 98÷56×100 which will give you 175 as the answer.

Answer:

175%

Step-by-step explanation:

98:56*100 =

(98*100):56 =

9800:56 = 175

Now we have: 98 is what percent of 56 = 175

Question: 98 is what percent of 56?

Percentage solution with steps:

Step 1: We make the assumption that 56 is 100% since it is our output value.

Step 2: We next represent the value we seek with x

Step 3: From step 1, it follows that 100%=56

Step 4: In the same vein, x%=98

Step 5: This gives us a pair of simple equations:

100%=56

x%=98

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100/x% = 56/98

Step 7: Taking the inverse (or reciprocal) of both sides yields

x%/100%=98/56

x = 175%

Therefore, 98 is 175% of 56.
