Answer»

Given : Two cyclists, 81 miles APART, START RIDING toward each other at the same time. One cycles 2 TIMES as fast as the other.

They meet 3 hours later,

To Find : what is the speed (in mi/h) of the faster cyclist

Solution:

speed of the slower cyclist. = R mi/hr

speed of the faster cyclist. = 2r mi/hr

riding toward each other

Hence effective speed = r + 2r = 3r mi/hr

Distance = Speed * Time

=> 81 = 3r * 3

=> r = 9

and 2r = 18

speed of the slower cyclist. = 9 mi/hr

speed of the faster cyclist. = 18 mi/hr

Answer» Here, ☆ Height of SOLID cylinder, h = 10 cm ☆ Radius of solid cylinder, R = 6 cm ☆ So, Volume of cylinder is $\tt \longrightarrow \: V_{(Cylinder)} \: = \pi \: {r}^{2} h$ $\tt \longrightarrow \: V_{(Cylinder)} = \pi \: {(6)}^{2} \times 10$ $\tt\implies \: \boxed{ \purple{ \tt \: V_{(Cylinder)} = 360 \: \pi \: {cm}^{3}}} - - (i)$ Now, CONE of same base and height is removed from solid cylinder. So, ☆ Height of cone, h = 10 cm ☆ Radius of cone, r = 6 cm ☆ So, Volume of cone is $\tt \longrightarrow \: V_{(Cone) } = \dfrac{1}{3} \pi \: {r}^{2} h$ $\tt \longrightarrow \: V_{(Cone) } = \dfrac{1}{3} \times \pi \: \times {(6)}^{2} \times 10$ $\tt \longrightarrow \: V_{(Cone) } = \dfrac{1}{3} \times \: \pi \times 6 \times 6 \times 10$ $\tt\implies \: \boxed{ \purple{ \tt \: V_{(Cone)} = 120 \: \pi \: {cm}^{3} }} - - (ii)$ $\red{ \bf \: Now, }$ $\boxed{ \purple{ \tt \: V_{(remaning \: solid)} \: = V_{(Cylinder)} - V_{(Cone)} }}$ $\tt \longrightarrow \: V_{(remaning \: solid)} = 360\pi \: - \: 120\pi$ $\tt\implies \: \boxed{ \green{ \bf \: V_{(remaning \: solid)} = 240 \: \pi \: {cm}^{3} }}$ $\large{\boxed{\boxed{\bf{Hence, option \: (c) \: is \: correct}}}}$

From a solid circular cylinder with height 10 cm and radius of the base 6 cm, a right circular cone of the same height and same base is removed, then the volume of remaining solid is (a) 280pie cm3(c) 240 pie cm3 (b) 330 pie cm3(d) 140 pie cm3

Answer»

Here,

☆ Height of SOLID cylinder, h = 10 cm

☆ Radius of solid cylinder, R = 6 cm

☆ So, Volume of cylinder is

$\tt \longrightarrow \: V_{(Cylinder)} \: = \pi \: {r}^{2} h$

$\tt \longrightarrow \: V_{(Cylinder)} = \pi \: {(6)}^{2} \times 10$

$\tt\implies \: \boxed{ \purple{ \tt \: V_{(Cylinder)} = 360 \: \pi \: {cm}^{3}}} - - (i)$

Now, CONE of same base and height is removed from solid cylinder.

So,

☆ Height of cone, h = 10 cm

☆ Radius of cone, r = 6 cm

☆ So, Volume of cone is

$\tt \longrightarrow \: V_{(Cone) } = \dfrac{1}{3} \pi \: {r}^{2} h$

$\tt \longrightarrow \: V_{(Cone) } = \dfrac{1}{3} \times \pi \: \times {(6)}^{2} \times 10$

$\tt \longrightarrow \: V_{(Cone) } = \dfrac{1}{3} \times \: \pi \times 6 \times 6 \times 10$

$\tt\implies \: \boxed{ \purple{ \tt \: V_{(Cone)} = 120 \: \pi \: {cm}^{3} }} - - (ii)$

$\red{ \bf \: Now, }$

$\boxed{ \purple{ \tt \: V_{(remaning \: solid)} \: = V_{(Cylinder)} - V_{(Cone)} }}$

$\tt \longrightarrow \: V_{(remaning \: solid)} = 360\pi \: - \: 120\pi$

$\tt\implies \: \boxed{ \green{ \bf \: V_{(remaning \: solid)} = 240 \: \pi \: {cm}^{3} }}$

Answer» Answer: Assuming the QUESTION actually means 9^(2x+1) = [81^(x+2)]/3^x… then you can change 9 and 81 to powers of 3…3^(2(2x+1)) = [3^(4(x+2))]/3^x the MULTIPLY both sides by 3^x… 3^(5x+2) = 3^(4x+8) this allows you to SOLVE for X by setting the powers of 3 = to eachother. 5x+2 = 4x+8 then subtract 4x from the right and left x +2 = 8 subtract 2 x=6 PS ….can be CHECKED by putting 6 back into original equation. Which yields 9^16 =2,541,865,828,329 =( 81^8)/(3^6) = 2,541,865,828,329 which is equal

20.

9 ^ 2 x + 1 is equal to 81 to the power x - 2 all over 3 to the power x

Answer»

Answer:

Assuming the QUESTION actually means 9^(2x+1) = [81^(x+2)]/3^x…

then you can change 9 and 81 to powers of 3…3^(2(2x+1)) = [3^(4(x+2))]/3^x

the MULTIPLY both sides by 3^x…

3^(5x+2) = 3^(4x+8)

this allows you to SOLVE for X by setting the powers of 3 = to eachother.

5x+2 = 4x+8

then subtract 4x from the right and left

x +2 = 8

subtract 2

x=6

PS ….can be CHECKED by putting 6 back into original equation.

Which yields 9^16 =2,541,865,828,329

=( 81^8)/(3^6) = 2,541,865,828,329 which is equal

Answer» Answer: RS. 3,000 Step-by-step explanation: A : B : C => 5 : 6 : 4 Now A-(B + C) = 200 (30/100)(15X)+(5/15)(70/100)15x−(70/100)15x=200 45/10x+35/10x−70/10x=200 => 10x = 2000, => x = 200 Hence TOTAL PROFIT = 200X15 = RS. 3000

Answer»

Answer:

RS. 3,000

Step-by-step explanation:

A : B : C => 5 : 6 : 4

Now A-(B + C) = 200

(30/100)*(15X)+(5/15)*(70/100)*15x−(70/100)*15x=200

45/10x+35/10x−70/10x=200

=> 10x = 2000,

=> x = 200

Hence TOTAL PROFIT = 200X15

= RS. 3000

Answer» Correct Question :- ● Ajay prakesh had old SCOOTER for rupees 10000 he paid 150 for road tax and HUNDRED as licence fee what price must he sell it to gain 20% . Solution :- COST Price of Scooter = Rs10000 He have to paid a road tax of Rs150 He had to pay license fee of Rs100 Total costprice of scooter = Rs10000 + 150 + 100 Total CP of scooter = Rs10250 Now, We have to find new SP of scooter As we know that, Profit = Profit % /100 * CP The seller wants to gain 20% profit Therefore, Profit = 20 / 100 * 10250 Profit = 2 * 1025 Profit = Rs2050 SP to gain 20% on selling a scooter = 10250 + 2050 = 12300 Hence, The selling price will be in order to gain 20% profit is 12300 $.$

Answer»

Correct Question :-

● Ajay prakesh had old SCOOTER for rupees 10000 he paid 150 for road tax and HUNDRED as licence fee what price must he sell it to gain 20% .

Solution :-

COST Price of Scooter = Rs10000

He have to paid a road tax of Rs150

He had to pay license fee of Rs100

Total costprice of scooter = Rs10000 + 150 + 100

Total CP of scooter = Rs10250

Now,

We have to find new SP of scooter

As we know that,

Profit = Profit % /100 * CP

The seller wants to gain 20% profit

Therefore,

Profit = 20 / 100 * 10250

Profit = 2 * 1025

Profit = Rs2050

SP to gain 20% on selling a scooter

= 10250 + 2050

= 12300

Hence, The selling price will be in order to gain 20% profit is 12300 $.$
