He have to buy 4 bags to put all the dirt at once.

Step-by-step explanation:

Radius = 17 inches

Height = 28 inches

Volume of dirt from the cylindrical hole = π(r x r) h

= π(17 x 17) 28

= (3.14) (289) 28

= 25408.88 cubic inches

1 foot = 12 inches

Volume of dirt the bag can hold= 24 x 18 x 48

= 20736 cubic inches of dirt

The man fills only one third of the bag.

The volume of dirt the man fills = (1/3)20736

= 6912 cubic inches

Total bags = 25408.88/6912

= 3.69

= appx. 4 bags

He have to buy 4 bags to put all the dirt at once.

20th term= 119

Step-by-step explanation:

Let the first term of AP be a

and common difference be d

nth term is given by,

= a+(n-1)d

6th term = 35

a+(6-1)d= 35

a+5d=35 -----------------(i)

13th term = 77

a+12d= 77----------------(ii)

Now, equation (ii) - (i)

a+12d-(a+5d)= 77-35

a+12d-a-5d= 42

7d=42

d=6

Now, from equation (i)

a= 35-5d= 35-5(6)= 35-30 = 5

20th term= a+19d= 5+19(6)= 119

In an arithmetic progression, the difference between any two successive terms is constant. By using this rule and the term numbers and values given, we can determine that the 20th term of the arithmetic progression is 119.

We have two pairs of term number and term value in the arithmetic progression (AP), which are (6, 35) and (13, 77). In an arithmetic progression, the difference between any two successive terms is constant, known as the common difference.

We can calculate the common difference (d) as (77-35)/(13-6) = 42/7 = 6.

Next, we find the first term (a) using the formula for the nth term of an AP, which is a = An - (n-1)*d. Using 6th term values, a = 35 - (6-1)*6 = 5.

Finally, we find the 20th term (A20) using the formula An = a + (n-1)*d. This gives us A20 = 5 + (20-1)*6 = 119.

So, the 20th term of this arithmetic progression is 119.

Answer:

The distance travelled was 314 inches.

Step-by-step explanation:

In order to calculate the distance that the unicycle will travel in 4 revolutions we first need to know the length of it's wheel, this is calculated by using the formula bellow:

length = 2*pi*r

Where r is the radius of the wheel that is equal to r = d/2

length = 2*pi*(d/2) = 2*3.14*(25/2) = 3.14*25 = 78.5 inches

If the wheel made 4 complete revolutions then the distance travelled was 4 times the length of it's wheels. We have:

distance = 4*length = 4*78.5 = 314 inches

The distance travelled was 314 inches.

  x = 0 and x = 4

Step-by-step explanation:

The two terms on the right have x as a common factor, so the function can be factored as ...

  y = x(x -4)

The zeros are the values of x that make y = 0, so we want the solutions to ...

  0 = x(x -4)

The Zero Product Rule tells us that a product will be zero if and only if at least one factor is zero. Here, the factors are x and (x-4). They are zero when ...

  x = 0   or   x = 4  . . . . . the zeros of the function

Answer:

a.) Let the total number be : x

∴(73.7÷x) ×100 = 55%

∴x= (73.7×100) ÷ 55

=> 7370÷55

∴x=134

Thus, Option-A.

----------------------------------------------------

b.) Let the percentage  be : x

∴x= (46÷65) ×100

Final answer:

To find the total amount of money Gavin and Jim got all together, we need to solve the equation 5x = x + £39, where x represents the amount Jim received. The total amount is £58.50.

Explanation:

To find the total amount of money that Gavin and Jim got altogether, we need to first determine the amounts they each received. Let's say the amount Jim received is represented as 'x'. According to the ratio of 5:2, Gavin received 5 times the amount Jim received, so Gavin received 5x.

We're given that Gavin gets £39 more than Jim, so we can set up the equation: 5x = x + £39. Simplifying this equation, we get 4x = £39. Dividing both sides by 4, we find that x = £9.75.

Now, we can calculate the total amount they got altogether by adding the amounts Jim and Gavin received: £9.75 + 5(£9.75) = £9.75 + £48.75 = £58.50.

Answer:

Step-by-step explanation:

1) 10a - 7a = 3a     {10a & 7a are like terms. So we can subtract}

5a + 2a - 4a = 7a - 4a = 3a        {5a, 2a, 4a are like tems}

So, 10a - 7a and 5a + 2a  - 4a are equivalent expressions

2) 9 - 4y and 4y - 9 are not equivalent

3)  6 + s means 6 is added to s

  6s means 6 is multiplied by s.

6 + s  and  6s are not equivalent expressions

4)  2c + 6c +9 - c - 4 = 2c + 6c - c + 9 - 4

                                 = 8c - c + 5

                                 = 7c + 5

7c + 5

2c + 6c +9 - c - 4  and 7c + 5 are equivalent expressions

Answer:

FG = 9.7ft

Step-by-step explanation:

Find the diagram in the attachment.

The diagram is a right angled triangle since one of its angle is 90°

Using SOH CAH TOA to calculate the length FG which is the hypotenuse.

According to SOH

Sin∠G = Opposite/Hypotenuse

To get the ∠G,

∠F+∠H+∠G = 180°

18°+90°+∠G = 180°

∠G = 180°-108°

∠G = 72°

Sin72° = 9.2/FG

FG = 9.2/sin72°

FG = 9.67feet

FG = 9.7ft (to the nearest tenth of a foot)

Final answer:

To find the number of rides that you went on at the fair given the total cost, $26, and the cost per ride, $3, you can use the equation $26 = $5 + $3r. Solving for r, you find that you went on 7 rides.

Explanation:

To write an equation that shows the number of rides, r, that you went on, we need to consider the total cost you spent and the cost per ride.

The cost to enter the fair is $5, and for every ride you go on, it costs $3. So, the equation would be:

Total Cost = Cost to Enter + Cost per Ride x Number of Rides

In this case, you spent a total of $26. Plugging in the values, we get:

$26 = $5 + $3r

Now, we can solve for r by isolating the variable:

$26 - $5 = $3r

$21 = $3r

To find the number of rides, divide both sides by $3:

r = $21/$3

r = 7

Therefore, you went on 7 rides at the fair.

The answer is 252 square inches

Given:

Given that the radius of the semicircle is 4 units.

We need to determine the area of the semicircle.

Area of the semicircle:

The area of the semicircle can be determined using the formula,

[tex]A=\frac{\pi r^2}{2}[/tex]

Substituting π = 3.14 and r = 4, we get;

[tex]A=\frac{3.14 \times (4)^2}{2}[/tex]

Simplifying, we get;

[tex]A=\frac{3.14 \times 16}{2}[/tex]

Multiplying, we get;

[tex]A=\frac{50.24}{2}[/tex]

Dividing, we get;

[tex]A=25.12[/tex]

Thus, the area of the semicircle is 25.12 square units.

Box A, weighing 212.04 kilograms, is 0.04 kilograms heavier than Box B, which weighs 212 kilograms. The difference in weight is due to differing volume and density.

The question is asking us to compare the weight of two boxes, Box A and Box B. Box A weighs 212.04 kilograms and Box B weighs 212 kilograms. To compare the weights, we subtract the weight of Box B from that of Box A: 212.04 kg - 212 kg = 0.04 kg. Therefore, the correct statement is: Box A weighs 0.04 of a kilogram more than Box B.

This question measures your understanding of decimal numbers and weight comparison in the metric system, specifically kilograms. In other words, 1 kilogram of one substance is equal in weight to 1 kilogram of another substance. It's the volume and density that might differ between them.
