I’m having trouble on number 4

Answer:

C

Step-by-step explanation:

radius squared * pi = 63.585

Answer:

$98.4.

Step-by-step explanation:

Since the university has decided that for the following year lecture costs will increase by 20%, workshop costs by 10%, and examination costs will stay the same, and that for level 2 the current hourly costs are 10, 24, and 60 respectively To determine how much the level 2 course cost in the following year, the following calculation must be performed:

10 x 1.2 + 24 x 1.1 + 60 = X

12 + 26.4 + 60 = X

98.4 = X

Thus, the level 2 course will cost $ 98.4 next year.

Answer:

Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of solid, liquid and gases carry sound waves from one point to another. Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.

Answer:

x = 5 / 3 = 1.667

Step-by-step explanation:

8*x+10-5*x-(15)=0

Solve  :    3x-5 = 0

Add  5  to both sides of the equation :

                     3x = 5

Divide both sides of the equation by 3:

                    x = 5/3 = 1.667

x = 5/3 = 1.667

Example 1:

The pros of Orthographic is that they can show hidden details and all of the connecting parts, they can be annotated to display material and finishes. The pros of Isometric projection is that they dont need many views and it gives accuracy, cons are is created a unorginized apperance by the lack of foreshortening, I would choose Isometric projection because it shows the size of the figure.

Example 2:

Orthographic projection is a good option for showing lots of detail and small things. The limitation is that with all of that detail, they can become quite messy and hard to understand to someone new to them. However, that is one of the pros of Isometric projection. It gives easy detail and is just as good as an Orthographic. Personally, I find Isometric projections easier to interpret.

Answer:

125%

Step-by-step explanation:

We are being asked what percent of 1600 is 2000.

The answer is 125%

1600 × 125% = 2000

Answer:

Step-by-step explanation:

100(2000-1600)/1600

100(400)/1600

40000/1600=25%

Answer:

70%

Step-by-step explanation:

Each blue line represents 10%.  Since there are 7 blue lines, we just multiply 10% by 7 and we get 70%

Answer:

70%

Step-by-step explanation:

7 out of 10 rectangles were filled so that's 7/10. 7/10 also equals 70/100. Therefore it's 70 out of 100 or 70%.

Step-by-step explanation:

Part A: Let see what number we can multiply by 3 to get 13.5

[tex]3x = 13.5[/tex]

[tex]x = 4.5[/tex]

so our answer is 4.5

Part B : Set up the proportion

3 and 13.5 correspond with each other and the question mark side corresponds with the 9 cm side.

let x = the side we are trying to find

[tex] \frac{3}{x} = \frac{13.5}{9} [/tex]

Cross multiply

[tex]27 = 13.5x[/tex]

[tex]x = 2[/tex]

so our answer is 2.

Answer:

[tex]k(3a-2b)[/tex]

Step-by-step explanation:

In the equation [tex]3ak-2bk[/tex], 'k' is the only common term.

Factor out 'k':

[tex]3ak-2bk\\\\\boxed{k(3a-2b)}[/tex]

Hope this helps.

Answer:

Simplifying

21p + 35q = 0

Solving

21p + 35q = 0

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-35q' to each side of the equation.

21p + 35q + -35q = 0 + -35q

Combine like terms: 35q + -35q = 0

21p + 0 = 0 + -35q

21p = 0 + -35q

Remove the zero:

21p = -35q

Divide each side by '21'.

p = -1.666666667q

Simplifying

p = -1.666666667q

The length of the radius of circle A is 24 units. The correct answer would be an option (A).

The arc is a portion of the circumference of a circle. The circumference of a circle is the distance or perimeter around a circle.

As per the question, we have

Arc length BC = 20π units and θ = 150°

The formula for calculating the arc states that:

Arc length = 2πr (θ/360)

Where r = the radius of the circle,

π = pi = 3.14

θ = the angle (in degrees) subtended by an arc at the center of the circle.

Substitute the known values, and we get

20π = 2πr (150/360)

10 = r (5/12)

r = 120/5

r = 24

Thus, the length of the radius of circle A is 24 units.

Answer: z=29 so Now: Cary is 38 years old while Dan is 29 years old.

In 5 years: Cary is 43 years old while Dan is 34 years old.

Step-by-step explanation: z=29 because 29+9=38 and 38+29=67 so 38+5=43 and 29+5=34.

Step-by-step explanation:

Answer:

Step-by-step explanation:

11/3 + (7 - 11/5)

LCM of 3 and 5 is 15 so we have

55/15 + (105/15 - 33/15)

= 160/15 - 33/15

= 127/15.

4y + 3 > 23          subtract 3 from both sides

4y > 20                divide both sides by 4

y > 5

-2y > -2                divide both sides by -2 (the order changes)

y < 1
