How far from the base of the house do you need to place a 15ft ladder so that it exactly reaches the top of a 12ft tall wall

1 answer:

4 0

It's a right triangle problem, and pretty obviously a multiple of the only Pythagorean Triple most folks know, 3²+4²=5². In this case we multiply the lengths by three getting

9²+12²=15²

If we place the 15 foot ladder 9 feet from the house it will hit the house at height 12 feet.

Answer: 9 feet

Answer: Both answers will be

$15x+18$

Step-by-step explanation:

Since we have given that

Cost of soccer balls = $15

Cost of baseball = $6

Cost of sweat socks = $5

a) Mr. Tonkery bought x number of soccer balls and 3 base balls .

So, our algebraic expression will be

$15x+3\times 6\\\\=15x+18$

b) Dennis, Eddie and Felix are on a base ball team. They each bought a baseball and x pair of sweat socks .

Since there are 3 members in a base ball team ,

Number of base ball they will purchase is given by

$3\times 6=18$

Number of sweat socks they will bought is given by

$5\times x\times 3=15x$

Total number they will purchase is given by

$15x+18$

Hence, both answers will be

$15x+18$

PLEASE HELP ASAP! PLS

Answer:

ok so it would take more effort to lift the 1 newton that is 4 m

Step-by-step explanation:

Work is done when a an object with a certain weight is moved at a given distance;

It is the product of force and distance and therefore varies directly to both distance and force.

Work = Force × distance;

For a 4 N box 0.5 m;

Work = 4 × 0.5

= 2 Joules

For a 1 N box 4 m

Work = 1 × 4

= 4 Joules

Therefore, Lifting a 1 N box for 4 m, will take more work

hope this helps

What is the difference between 9 - 4 1/5

erica [24]

Hey there!☺

$Answer:\boxed{4\frac{4}{5}}$

$Explanation:$

$9-4\frac{1}{5}$

Subtract the whole number by the fraction.

$\frac{24}{5}$

24/5 needs to be simplified so we will rewrite it like this:

$4\frac{4}{5}$

Hope this helps!
