HELP ME ANSWER THIS PLEASEE!

Diameter of a roller = 140 cm

Radius of the roller :

[tex] =\tt \frac{diameter}{2} [/tex]

[tex] =\tt \frac{140}{2} [/tex]

[tex] = \tt70 \: cm[/tex]

Thus, the radius of the roller = 70 cm

Height of roller = 2 m = 2×100 cm = 200 cm

Curved surface area of roller = 1 revolution

The curved surface area of this roller :

[tex] =\tt 2\pi rh[/tex]

[tex] = \tt2 \times 3.14 \times 70 \times 200[/tex]

[tex] =\tt87920 \: {cm}^{2} [/tex]

Thus, the curved surface area of the roller = 87920 cm²

Number of revolutions that needs to be done to level the ground = 350

Distance the roller will travel to get leveled :

[tex] =\tt 87920 \times 350[/tex]

[tex] = \tt43960000 \: cm[/tex]

[tex] = \tt \frac{43960000}{100} \: m[/tex]

[tex] = \tt439600 \: m[/tex]

Thus, to level the playground the distance the roller should cover = 539600 m

Cost of covering one square meter of land = 75 Paise

Cost of covering 539600 m of land :

[tex] =\tt 539600 \times \frac{75}{100} \: Rs[/tex]

[tex] = \tt \frac{539600 \times 75}{100} \: Rs[/tex]

[tex] =\tt \frac{40470000}{100} \: Rs[/tex]

[tex]\color{plum} = \tt\bold{404700 \: rupees}[/tex]

▪︎The cost of leveling the playground = 404700 Rs

Answer:5.6 x 10^5

Step-by-step explanation:

When ever we hear sum, what comes to our mind must be addition

Here we are Adding 5.3 x 10 to the fifth power= 5.3 x 10^5 to

3.8 x 10 to the fourth power = 3.8 x 10^4

First,

Expanding the scientific notation we have that

5.3 x 10^5 = 530,000

3.8 x 10^4=     38,000

Add           = 568,000

Putting back in Scientific notation  we have 568000 = 5.6 x 10^5

If they can be expressed in the form of y=kx, they are proportional. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

Answer:

Dotted line

Step-by-step explanation:

when using the > or < symbols you put a dotted line because the line is not included in the shaded area.

If the symbols were a < or a > you would put a solid line.

Answer: The fraction of the minutes did Billy use = [tex]\dfrac15[/tex].

Step-by-step explanation:

Let x = Total minutes given in the plan.

Last month, Jodie used [tex]\dfrac34[/tex] of the minutes.

Remaining minutes = [tex]x-\dfrac34x=\dfrac14x[/tex]

Billy used = [tex]\dfrac45(\dfrac14x)=\dfrac{x}{5}[/tex]  minutes

Fraction of the minutes used by Billy = [tex]\dfrac{\dfrac{x}{5}}{x}=\dfrac15[/tex]

Hence, the fraction of the minutes did Billy use = [tex]\dfrac15[/tex].

Answer:

the answer is 15

Step-by-step explanation:

because 110÷7$

The maximum number of 15 cherry pies she can buy.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Simone is buying pies for a party.

One cherry pie costs $7,

and one apple pie costs $5.

If Simone needs to buy at least 18 pies and has no more than $110 to spend,

the maximum number of cherry pies,

= 110/7

= 15.71.

If 15 cherry pies, then 3 apple pies.

The total amount = 15 x 7 + 3 x 5

= 110

Therefore, 15 is the maximum number.

Answer: the answer is 6000

Step-by-step explanation:

The division is one of the four fundamental arithmetic operations. The distance travelled by the driver in 12 days is 800 miles.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

A truck driver can travel 200 miles in 3 days. Therefore, the distance which the truck can travel in one day is,

Distance in a day = 200miles/3day = 66.6667 miles/day

The distance that the truck can travel in 12 days are,

Distance = 66.6667miles/day ×12 day = 800 miles

Hence, the distance travelled by the driver in 12 days is 800 miles.

Step-by-step explanation:

Answer:

2x (2 or 2/1)

Step-by-step explanation:

The slope is 2/1, or 2x because the height between any two given intercepting points is two times higher than it is far.

Take for example the intercepting points at (6, 1) and (7, 3). Since slope is rise/run, the slope has risen 2 and 'run' 1. This makes the slope 2/1.

Answer:

Please check the explanation.

Step-by-step explanation:

Let the coordinates of the point F be (x, y).

When a point F(x, y) is reflected over the x-axis, the x-coordinate of the point F remains the same, and the y-coordinate of the point reverses the sign.

Thus, the rule of reflection over the x-axis:

F(x, y)   →    F'(x, -y)

Here,

F'(x, -y) would be coordinates of point F after the reflection over the x-axis.

Let say, the point F(1, 2).

The coordinate of the point F after the reflection over the x-axis would be:

F(1, 2)   →    F'(1, -2)

Thus, F'(1, -2) would be the coordinates of point F after the reflection over the x-axis.

Answer: v=43πr3 where r is the radius. You have the diameter, that is the double of the radius, so r=92=4.5 inches. v=43π4.53=381.69 cubic inches.

Answer:

381.7

Step-by-step explanation:

to get the volume of a sphere the formula is:

V=4 /3πr3

(remember basketball isn't a circle because it is 3-d)

you plug in the radius to that formula and boom you got your answer!

(remember radius is half the diameter, and half of 9 is 4.5)

so your answer would be:

Answer:

B, 7/24

Step-by-step explanation:

(x=theta)

sec(x) = 1/cos(x) so 1/cos(x) = 25/24

[tex](\frac{1}{cosx})^-1 = (\frac{25}{24} )^-1\\\\cos(x) = 24/25[/tex]

Then use the cos^-1 function on your calculator to find out theta.

Then tan your found value of theta.

You should find that tan (theta) = 7/24
