Step-by-step explanation:

get the first part of each fraction to something divisible by the second part

4 · 3= 12/6

1 · 3= 3/3

12÷2= 2 3÷3= 1

2/1

Answer:

Correct answer is A 2:1

Step-by-step explanation:

When writing a unit rate the denominator is always 1

If you want to obtain a unit rate you divide both quantities by the second one.

what is a unit rate?

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

Answer:

option 1

Step-by-step explanation:

the square root of 6 is 2.44949, rounded it's 2.4

the square root of 42 is 6.48074, rounded it's 6.5

in option 1 the 6 is placed after the 2 because it is point 4, not quite 2 but a bit bigger than 2 but less than 3.

same thing for 42, it is placed after 6 because it is not quite 6 but not over 7. i hope this helped

Answer:

By solving the equation with the order of operations, the correct answer is: 80

Answer:

x=40

Step-by-step explanation:

2x+5=85

2x+5-5=85-5

2x=80

\frac{2x}{2}=\frac{80}{2}

x=40

The value of x for the given expression in angles will be 40. The correct option is B.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet. The supplementary angles are defined as when the sum of the angles is equal to 180 degrees.

Given that ∠2 equals (2x+5)degrees and ∠3 equals 85 degrees. The value of x will be calculated by using the supplementary property of angles.

2x+5=85

2x+5-5=85-5

2x=80

x=40

Therefore, the value of x for the given expression in angles will be 40. The correct option is B.

Answer:

14.76

Step-by-step explanation:

First find the length of the diagonal across the bottom using the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

12^2+5^2 = c^2

144+25 = c^2

169 = c^2

Take the square root of each side

sqrt(169) = sqrt(c^2)

13 = c

Then find the length of the diagonal across the  middle using the Pythagorean theorem

7^2 + c^2 = d^2

7^2 + 13^2 = d^2

49+ 169 = d^2

218 = d^2

Take the square root of each side

sqrt(218) = sqrt(d^2)

14.76482306 = d

Answer:

84%

Step-by-step explanation:

The mean has 50% below the mean and 50 % above the mean

The mean is 103.47

The standard deviation is 4.07

Add the mean and the standard deviation

103.47+4.07 = 107.54

We want to know how much data is below the mean plus one standard deviation

Within one standard deviation is 68% , but that is on both sides, we are  only needed on the right side so we need 1/2 of the 68 = 34

50+34 = 84

Answer:

Step-by-step explanation:

f(x) = 2x2 – 1 and g(x) = x + 3,

f(g(-5))

First find g(-5)

g(-5) = -5 + 3

g(-5) = -2

Then substitute into f(x)

f(-2) = 2 ( -2) ^2 -1

      = 2 ( 4) -1

      = 8-1

Answer:

The domain of f(x) is x>-2, so the range of f-1(x) is y>-2

The range of f(x) is y>-1, so the domain of the f-1(x) is x>-1

Step-by-step explanation:

To solve this question, we need to know the definition of domain and range.

The domain of a function is defined as all the possible input x-values while the range is defined as all the possible output y-values.

For f(x), domain for x is; x ≥ 1 and range is; y ≥ 2

For f⁻¹(x); domain is; x ≥ 2 and range is; x ≥ 1

We are given the function;

f(x) = [tex](\sqrt{x - 1} ) + 2[/tex]

Now, when x = 1, we will have zero inside the square root sign and this means that any x-value less than 1 will make the value inside the square root symbol to be negative which will result in an imaginary root.

Thus, we can say that, the domain for x is; x ≥ 1

Putting x = 1, we can find the least range value;

f(x) = 0 + 2

f(x) = 2

Thus, the range will be; y ≥ 2

Now, we want to find the range of f⁻¹(x)

This means an inverse of the original equation.

Thus;

f⁻¹(x) = [tex](x - 2)^{2} + 1[/tex]

Let's put x = 2;

f⁻¹(x) = (2 -2)² + 1

f⁻¹(x) = 1

Since x=2 gives the bracket to be zero, it means the domain is; x ≥ 2 and range is; x ≥ 1

Answer:

  m∠MON = 99°

Step-by-step explanation:

A "straight angle" has a measure of 180°, so the two given angles will have that value as their sum.

  m∠MON +m∠LOM = m∠LON

  (8x -13°) +(7x -17°) = 180°

  15x -30° = 180° . . . . collect terms

  x -2° = 12° . . . . . . . . divide by 15

  x = 14° . . . . . . . . . . . add 2°

Now we can find the measures of the angles.

  m∠MON = 8x -13° = 8(14°) -13°

  m∠MON = 99°

_____

Check

m∠LOM = 7x -17° = 7(14°) -17° = 81°

The sum of 81° and 99° is 180°, as it should be.

A linear pair of angles is formed when two lines intersect.

A linear pair of angles must add up to 180°.

angle MON = 8x - 13°

angle LOM = 7x - 17°

The measure of angle MON .

angle MON + angle LOM = 180°

or, (8x - 13°) + (7x - 17°) = 180°

or, 15x - 30°= 180°

or, 15x = 180° + 30°

or, x = 210/15 = 14°

angle MON = 8x - 13°

By putting the value of x, we get

angle MON = 8(14) - 13°

angle MON = 99°
