Someone help please answer question 1

Answer:

(a) C = $9250

(b) n = 21 tons

Step-by-step explanation:

(a)   11 tons being transported, so n = 11.

                ∴ C = 250 (11) + 650

                        C = $9250

(b)   C = $11,750

       ∴ 11750 = 250n + 6500

                250n = 5250

                   n = 21 tons

Answer:

Actual volume = 40 cm^3.

Step-by-step explanation:

15% = 0.15 as a decimal fraction.

Let the actual volume be x cm^3, then we have the equation:

x + 0.15x = 46

1.15x = 46

x   = 46 / 1.15  

    = 40 cm^3.

Givens

Formula

V = pi * r^2 * h                                         Substitute givens into formula

Solution

198 cm^3 = 3.14 * 8.8 * r^2                     Combine the right

198 = 27.632 * r^2                                  Divide both sides by 27.632

198 / 27.632 = 27.632 * r^2 / 27.632

7.1656 = r^2                                            Switch the equation

r^2 =  7.1656                                           Take the square root of both sides

√r^2 =  √7.1656  

r = 2.6768

Answer

r = 2.7 rounded to the nearest tenth

The expression that represents the volume of the empty space is 9³ - 4/3π(4.5)³

The cube box has a side length of 9.

So, the volume of the box is:

V = 9³

The sphere has a radius of 4.5.

So, the volume of the sphere is:

v = 4/3π(4.5)³

Calculate the difference between both volumes:

d = 9³ - 4/3π(4.5)³

Hence, the expression that represents the volume of the empty space is 9³ - 4/3π(4.5)³

A = 25

Answer:

below

Step-by-step explanation:

• We know that the initial height of Candle A is 201 millimeters and of Candle B is 290 millimeters which means the first statement is not true.

• To find the rate at which the Candle A is decreasing, we simply have to divide 201 - 177 with 4.

24 / 4 = 6

       As we can see Candle A is decreasing at a faster rate of 6 than the rate of decreasing of Candle B which is 5. This means that second statement is true.

• To find out after how many hours will the Candle B burn out we simply have to divide the initial value with the rate of change which is 5.

290 / 5 = 58

       Candle B will burn out after 58 hours. This statement is true.

• We simply have to multiply the rate of change with 10 and after that subtract the value that we get from the initial value of Candle A.

10 x 6 = 60

201 - 60 = 141

After 10 hours the height of Candle a will be 141 millimeters. This statement is true.

• We know that Candle A is burning out at a faster rate and that the Candle B was higher at start which means that

       Candle A will burn out before Candle B. This statement is true.

Answer:

The formula to get the circumference of a circle is [tex]C=2*\pi * r[/tex] but in this case we see that a diameter is being used therefore we can get rid of the 2 and the r because that is what the diameter and just replace d into there like this [tex]C=d*\pi[/tex].

We can then input the value and we get that [tex]C=1*\pi[/tex] which then just narrows down to [tex]C=3.142[/tex].

Factor out common term [tex]3x[/tex]:

[tex]\implies 3x \cdot x - 3 \cdot 3x[/tex]

Answer:

d = 306 m

Step-by-step explanation:

calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (10, 20) and (x₂, y₂ ) = (280, 164) ← house and beach coordinates

d = [tex]\sqrt{(280-10)^2+(164-20)^2}[/tex]

   = [tex]\sqrt{270^2+144^2}[/tex]

   = [tex]\sqrt{72900+20736}[/tex]

   = [tex]\sqrt{93636}[/tex]

   = 306 m

Answer:

The distance from Francesca's house to the beach is 306 meters.

Step-by-step explanation:

Use the Pythagorean Theorem to find the straight-line distance from Francesca's house to the beach.

Step 1 Find the length of the horizontal leg.

The length of the horizontal leg is the absolute value of the difference between the x- coordinates of the points (280,20) and (10,20).

|280 - 10| = 270

The length of the horizontal leg is 270 meters

Step 2 Find the length of the vertical leg.

The length of the vertical leg is the absolute value of the difference between the y- coordinates of the points (280,164) and (280,20)

|164 - 20| = 144

The length of the vertical leg is 144 meters.

Step 3 Let a = 270 and b = 144. Let c represent the length of the hypotenuse. Use the Pythagorean Theorem to find c.

a² + b² = c²

270² + 144² = c² Substitute into the formula.

72900 + 20736 = c² Simplify.

93636 = c² Add.

√93636 = c Take the square root of both sides.

306 = c Simplify.

The distance from Francesca's house to the beach is 306 meters.

Answer:

3/y^2

Step-by-step explanation:

1. Rewrite the division as a fraction.

= 12y^7/4y^9

2. Cancel the common factor of 12 and 4

= 4(3y^7)/4y^9

= 3y^7/y^9

3. Cancel the common factor of y^7 and y^9

= y^7 ⋅ 3/y^9

= 3/y^2
