Answer:

-25 °F

Step-by-step explanation:

First, we would be multiply 3 by 5 to find the number we would be subtracting from the original

3 * 5 would give us 15

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

A path 5m wide is to be built along the border and inside a square garden of side 90m. Find the cost of cementing the path at th
gizmo_the_mogwai [7]

Answer:

Total cost of cementing the path = Rs. 17,000.

Step-by-step explanation:

Let the square garden be ABCD

Let the region inside the garden (ABCD) be WXYZ.

<u>Given the following data;</u>

Length of sides of ABCD = 90m

Width of path = 5m

Cost = Rs. 10 per m²

Area of ABCD = 90 * 90

Area of ABCD = 8100m²

<em>To find the area of WXYZ;</em>

WX = WZ = 90 - (5 + 5)

WX = WZ = 90 - 10

WX = WZ = 80m

Area of WXYZ = WX * WZ

Substituting into the equation, we have;

Area of WXYZ = 80 * 80

Area of WXYZ = 6400 m²

Area of path = Area of ABCD - Area of WXYZ

Area of path = 8100 - 6400

Area of path = 1700 m²

Total cost of cementing the path = Area of path * cost

Total cost of cementing the path = 1700 * 10

<em>Total cost of cementing the path = Rs. 17,000</em>
