How to round the number 3.987 to the nearest tenths

1 answer:

8 0

First you go the tenths place which is the number 9 stands. You look to the left of the number. Here is the tricky part if the number is under 5 for example 1 2 3 4. The number stays the same and everything behind that number is 0. If the number is 5 or higher the number goes up one and everything behind it is 0. So 3.987 rounded to the nearest tenth is 4.000

The Martin's swimming pool is a square and is in the center of a square plot that is 35 meters on a side. They have 1,104 square

Naya [18.7K]

Answer:

side of the pool = 11 m

Step-by-step explanation:

Square Plot:

side = 35 m

Area = 35 * 35 = 1225 sq.m

Area of lawn = 1104 sq.m

Swimming pool:

Area of the Swimming pool = 1225 - 1104 = 121 sq.m

side * side = 121 = 11 * 11

side = √11 * 11

side of the pool = 11 m

The roof of this garden shed has a gradient of 0.35. find the height of the shed

Ilya [14]

The height of the shed is 2.325 m

The complete question is

The roof of a lean-to-garden shed has a gradient of 0.35.find the height....they have given the base as 1.5m and a shorter height 1.8m its like a house

<h3>What is a right Triangle ?</h3>

In a Triangle when one angle is 90 degree , the triangle is called Right Triangle .

Structure of the house is a right triangle with base = 1.5m

(height of that triangle)/1.5 = 35/100

height of that triangle = 1.5*0.35 = 0.5250

Ans: greater height of the lean-to = 1.8 + 0.5250 = 2.325 meters.

The height of the shed is 2.325 m.

Solve 4/x-4=x/x-4-4/3 for x and determine if the solution is extraneous or not

4vir4ik [10]

Answer:

x = 4 (extraneous solution)

Step-by-step explanation:

$\frac { 4 } { x - 4 } = \frac { x } { x - 4 } - \frac { 4 } { 3 } \\ \frac { 4 } { x - 4 } - \frac { x } { x - 4 } = - \frac { 4 } { 3 } \\ \frac { 4 - x } { x - 4 } = - \frac { 4 } { 3 } \\ 3 ( 4 - x ) = - 4 ( x - 4 ) \\ 1 2 - 3 x = - 4 x + 1 6 \\ 4 x - 3 x = 1 6 - 1 2 \\ x = 4 \\$

This solution is extraneous. Reason being that even if it can be solved algebraically, it is still not a valid solution because if we substitute back $x=4$ , we will get two fractions with zero denominator which would be undefined.
