36 is what percent less than 60

mestny [16]

36/60 = 18 / 30 = 9 / 15 = 3/5 , so 36 is 60% of 60, or 40% less than 60. This question is worded oddly, is that what you're looking for?

Which transformation of f(x)=3^x does h(x)=-3^x-7 represent?

vaieri [72.5K]

F(x) = 3^x and g(x) = 3^x - 7 => h(x) = f(x) - 7. This is f(x) has been translated 7 units downward.

If you graph f(x) you can obtain h(x) by shifting the graph of f(x) 7 units downward.

For a sale, a store decreases its prices on all items by 25%. An item that costs $120 before the sale now costs $120 - 0,25($120

Alexxandr [17]

Answer:

$Cost = \$120 * 1 - \$120 * 0.25$

Step-by-step explanation:

Given

$Cost = \$120 - 0.25(\$120)$

Required

Solve using distributive property

$Cost = \$120 - 0.25(\$120)$

$\$120$ can be rewritten as $1(\$120)$

So:

$Cost = 1(\$120) - 0.25(\$120)$

Factorize:

$Cost = \$120(1 - 0.25)$

Now, we can apply distributive property on the expression;

$Cost = \$120 * 1 - \$120 * 0.25$

Hence, the above is an equivalent expression.

Solving further, we have

$Cost = \$120 - \$30$

$Cost = \$90$
