Answer:

7/9 < 5/6

Step-by-step explanation:

The denominator is the common factor of the denominators

That is 54

So we have

7/9 * 6/6 = 42/54

5/6 * 9/9 = 45/54

y= 5/2x + 10
y= -1/2x + 1/2
y= 3/2x - 11/2
y= 1/2x - 2
y= 4/3x - 7/3
y=3/4x - 10

Answers

Answer:

to a function is increasing we have to find the slope of the function

the higher the slope the faster the growth

Step-by-step explanation:

slope = 5/2. which is 2.5slope 2 = -1/2 which is -0.5slope 3 = 3/2 which is 1.5slope 4 = 1/2 which is 0.5slope 5= 4/3 which is 1.33slope 6 = 3/4 which is 0.75

so the function in increasing order

y= -1/2x + 1/2

y= 1/2x - 2

y=3/4x - 10

y=4/3x -7/3

y=3/2x-11/2

y=5/2x +10

In 2000, the world population was 6.1 billion. In 2015, the world population was 7.3 billion. Work out the percentage increase in population. Give your answer correct to 1 decimal place.

Answers

Answer:

19.7%

Step-by-step explanation:

Given that,

In 2000, the world population was 6.1 billion.

In 2015, the world population was 7.3 billion.

We need to find the percentage increase in population. The percent increase in this case is given by :

[tex]\%=\dfrac{7.3-6.1}{6.1}\times 100\\\\=19.67\%\\\\=19.7\%[/tex]

So, the increase in population is 19.7%.

In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°. Find all possible values of ∠V, to the nearest 10th of a degree.

Answers

Answer:

The possible values for ∠V is 81.2° and 98.8°

Step-by-step explanation:

In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°. Find all possible values of ∠V, to the nearest 10th of a degree.

We solve the above question using Sine rule

Sine rule

= u/sin U = v/sin V

In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°

Hence:

7.6/sin 68° = 8.1/sin V

Cross Multiply

7.6 × sin V = sin 68° × 8.1

sin V = sin 68° × 8.1/7.6

V = arc sin ( sin 68° × 8.1/7.6)

V = arc sin (0.99)

V = 81.18°

Another value for V = 180° - 81.18°

= 98.82°

Therefore, the possible values for ∠V approximately to the nearest tenth of a degree is 81.2° and 98.8°

Please help me with this x+125+d=1,245

Answers

Answer:

x=1120-d

Step-by-step explanation:

Answer:

x = 1120 - d

Step-by-step explanation:

Hi there!

We can simplify this using orders of operations.

First, subtract 125 from both sides to get x + d = 1120.

To isolate x, just subtract d from both sides.

If you give me a value for d, i can solve the full problem.

Need help bro geometry aint it

Answers

Answer:

∠CAD = 44⁰

∠ACD = 44⁰

∠ACB =  136⁰

∠ABC = 22⁰

Step-by-step explanation:

To calculate m∠CAD;

Line AD = Line DC,

thus ∠CAD = ∠ACD = ¹/₂(180 - 92°) [sum of angles in a triangle.]

       ∠CAD =  ¹/₂ x 88 = 44⁰

Also, ∠ACD = 44⁰

To calculate  m∠ACB;

∠ACB = 180 - ∠ACD [Sum of angles on a straight line]

∠ACB = 180 - 44

∠ACB =  136⁰

To calculate m∠ABC;

Line CB = Line CA

Thus, ∠ABC = ∠CAB = ¹/₂(180 - ∠ACB) [sum of angles in a triangle.]

∠ABC =  ¹/₂(180 - 136)

∠ABC =  ¹/₂ x 44

∠ABC = 22⁰
