Answer:

detail in steps

Step-by-step explanation:

Red car: 150 / 60 = 2.5 hour s for the travel

Blue car: 150 / 25 = 6 hours, it start 2.5 hours earlier

2.5 + 2.5 = 5 it still has 6 - 5 = 1 hour away to the end point while Red car is at end point.

* Red car will pass Blue car to arrive end point earlier.

When Red car will pass Blue car:

25 * ( 2.5 + x) = 60 x

62.5 + 25x = 60x

35x = 62.5

x = 62.5 / 35 = 12.5 / 7 = 1.79 hour after Red car started

i.e at 60 x 1.79 = 107.4 miles from start point the Red car will pass Blue car

Answer:

506.7 cm²

Step-by-step explanation:

The amount of cardboard needed would be the surface area of the cone,

S= pi(r)(l+r) where r is the radius and l is the slant height.

You can find l using the Pythagorean theorem. l²=r²+h² which is l²=6²+20² and you get l = √436.

Plug r and l into the equation: S = 6pi(√436 + 6) = 506.7 cm²

Let me know if you have any questions about my steps!

Answer:

-5/8a - 2.8b

Step-by-step explanation:

-3/8a + 3.2b + (-6b) - 1/4a

=> -3/8a + 3.2b + (-6b) - 2/8a

=> -5/8a + 3.2b - 6b

=> -5/8a - 2.8b

Therefore, -5/8a - 2.8b is the solution to your problem.

A rectangular box has length 20cm, width 6cm and height 4cm. find how many cubes of size 2cm that will fit into the box.

Papessa [141]

Answer:

$\boxed{\pink{\sf The \ number \ of \ cubes \ that \ can \ be \ fitted \ is 60 .}}$

Step-by-step explanation:

Given dimensions of the box = 20cm × 6cm × 4cm .

Dimension of the cube = 2cm × 2cm × 2cm .

Therefore the number of cubes that can be fitted into the box will be equal to the Volume of box divided by the Volume of the cube. So ,

$\boxed{\red{\bf \implies No. \ of \ cubes \ = \dfrac{Volume \ of \ box}{Volume \ of \ cube }}}$

$\bf \implies n_{cubes} = \dfrac{20cm \times 6cm \times 4cm .}{2cm \times 2cm \times 2cm } \\\\\bf\implies n_{cubes} = 10 \ times 3cm \times 2cm \\\\\implies \boxed{\bf n_{cubes}= 60 }$

<h3>Hence the number of cubes that can be fitted in the box is 60 .</h3>
