Lian has $1.00. She has only nickels and dimes. Lian has twice as many dimes as nickels. How many dimes does she have?

Anna11 [10]

Answer: 8

Step-by-step explanation:

Given

Lian has $\$1.00$ and she has twice as many dimes as nickels

Suppose she has $x$ nickels

So, the number of dimes is $2x$

Nickel is equivalent to 5 cents and dime is equivalent to 10 cent

$\therefore \ x(0.05)+2x(0.1)=1\\\Rightarrow 0.05x+0.2x=1\\\Rightarrow 0.25x=1\\\Rightarrow x=4$

Therefore she has 8 dimes with her.

A 14 foot ladder is placed against a wall. It is placed 5 feet from the base of the wall.

Vladimir [108]

Answer:

c = 18.47

Step-by-step explanation:

This would create a triangle in which the length of the wall would be the missing side. We can use the Pythagorean Theorem to find this:

1. $a^{2}$ + $b^{2}$ = $c^{2}$

2. $5^{2}$ + $14^{2}$ = $c^{2}$

3. 25 + 196 = $c^{2}$

4. 221 = $c^{2}$

5. $\sqrt{221}$ = c

6. 18.47 = c
