An electrician needs 3 rolls of electrical wire to wire each room in a house. How many rooms can he wire with 3/4 of a roll of wire?

Answers

Answer 1

Answer:

He can wire

[tex] \frac{1}{4} [/tex]

of a room with 3/4 of a roll of wire.

Step-by-step explanation:

We can solve by using proportions.

Let's set it up.

[tex] \frac{3 \: rolls}{1 \: room} = \frac{ \frac{3}{4} \: of \: a \: roll}{x} [/tex]

We are now going to cross multiply. By cross-multiplting, you would get:

[tex] \frac{3}{4} = 3x[/tex]

You are now going to divide both numbers by 3 in order to get the x by itself.

[tex] \frac{ \frac{3}{4} }{3} = \frac{3x}{3} [/tex]

By dividing, you get:

[tex] \frac{1}{4} = x[/tex]

Therefore, the answer is 1/4.

Answer 2

The number of rooms he can wire with 3/4 of a roll of wire is 1/4.

What are proportions?

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Given that, an electrician needs 3 rolls of electrical wire to wire each room in a house.

Let the number of rooms he can wire with 3/4 of a roll of wire be x.

Now, the proportion is

[tex]\frac{3}{1}=\frac{\frac{3}{4} }{x}[/tex]

3x=3/4

x=1/4

Therefor, number of rooms he can wire is 1/4.

Answer:

See the answer below.

Step-by-step explanation:

The Pythagoras theorem for a right triangle is

c^2 = a^2 + b^2     where c = hypotenuse and a, b are the legs of the triangle.

3  positive integers which fit this formula  are called Pythagorean Triples.

3,4 5 are a triple because 5^2 = 3^2 + 4^2 ( 25 = 9 + 16).

and also  17^2 = 15^2 + 8^2  ( 289 = 225 + 64).

Step-by-step explanation:

Pythagorean theorem is [tex]a^{2} + b^{2} =c^{2}[/tex] (c being the largest number)

Pythagorean triples are 3 positive numbers that make this equation true.

let's start with 3,4,5

3²+4²=5²

9+16=25

25=25

Since it's true, it's a triple.

Now 8,15,17

8²+15²=17²

64+225=289

289=289

This is also true, so it's also a triple

9. Evaluate the ceiling function for the given value.
A. f(x) = ⌈x⌉; x = −7.4

B. g(x) = ceiling (x, 0.50);
x = 21.27

Answers

Given:

A. f(x) = ⌈x⌉; x = −7.4

B. g(x) = ceiling (x, 0.50);  x = 21.27

To find:

The values of ceiling function for the given value.

Solution:

A.

We have,

f(x) = ⌈x⌉; x = −7.4

Here, f(x) is a ceiling function, so we need to find the nearest next integer value because if m < x ≤ n, then ⌈x⌉ = n, where m and n are integers.

Now,

f(-7.4) = ⌈-7.4⌉

f(-7.4) = -7

Therefore, the value of f(x) is -7 at x=-7.4.

B.

g(x) = ceiling (x, 0.50);  x = 21.27

Here, g(x) is a ceiling function with 0.50, so we need to find the nearest next multiple of 0.50 because if m < x ≤ n, then ⌈x⌉ = n, where, m and n are multiples of 0.50.

Now,

g(21.27) = ceiling (21.27, 0.50)

g(21.27) = 21.50

Therefore, the value of g(x) is 21.50 at x=21.27.
