The weight of an object on the moon varies directly with its weight on the earth. If an object weighing 95 lbs on the moon weigh

Luda [366]

ANSWER

450lb

EXPLANATION

If the weight, m of an object on the moon varies directly as the weight of an object e, on the earth, then we can write the mathematical statement,.
$m \propto \: e$
We introduce the constant of proportionality to obtain,

$m = ke$

When, m=95, e=570,

This implies that,

$95 = 570k$
$k = \frac{95}{570}$

$k = \frac{1}{6}$

The equation now becomes,

$m = \frac{1}{6} e$

We want to find e, when m=2700,

$m = \frac{1}{6} \times 2700$

$m =450lb$

What is the total volume of glass used to make the award?

vladimir1956 [14]

Answer:

204 in^3

Step-by-step explanation:

The volume of the base square is V=lwh.

When we substitute our givens, it becomes V=6(4)(2). This equals 48 in^3.

The volume of the triangle is V=.5lwh.

When we substitute our givens, it becomes V=.5(6)(4)(15-2). This equals 156 in^3.

When we add 48 and 156, we get 204 in^3.

Hope this helps :)

Marc saved 30% of his monthly salary each month. His monthly salary in December was $ 3650. In January, his salary increased by

DiKsa [7]

Marc saved $2,533 in January than in December.

Step by Step calculation.

Given the details below :

Salary In December =$3,650

In January, Increased by 12%

Marc saves 30% of $3,650 in December

New salary can then be calculated as :

= Initial salary * % increase / 100 + Initial salary

= 3,650 * 12 / 100 + 3,650

= 3,650 * 0.12 + 3,650

= 4,088

The difference will now be

= 4,088 - 3650

= $438

Since Marc saves in December 30% of $3,650

= 30% of $3,650

= $1,095

Saves in January

= 1,095 + 438

= $2,533
