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

$Cost = \$120 - \$30$

$Cost = \$90$

A tree standing vertically on level ground casts a 140 foot long shadow. The angle of elevation from the end of the shadow to th

fredd [130]

<span>Let the height of the tree be h foot. Trigonometric ratio for tangent = Opposite side / adjacent side----(1) Since the tree is standing vertically on a level ground, the three points, [ Top of the tree, the point where the tree touches the ground and the point where the shadow ends] form a right angled triangle. Applying (1) for the above three points, tan(24.7)=(height of the tree)/(length of shadow) Hence, height of the tree = tan(24.7)*(length of the shadow) = (0.46)*140 = 65 foot (Rounding off to the nearest foot)</span>

As an estimation we are told 5 miles is 8 km. <br>Convert 60 km to miles.

blagie [28]

Answer:

37.5 miles

Step-by-step explanation:

We can find the rate of conversion by dividing kilometers by miles. 5÷8=1.6, so 1.6 km = 1 mile. Now we can divide 60 by 1.6 to find miles.

$60/1.6=37.5$
