A group of workers took 123.6 hours to
complete a job. A smaller group of workers
will complete the same job, but it will take
them 1.15 times as long as it took the first
group. How long did it take the smaller group
to complete the job?

Answers

Answer 1

Answer:

137.814 hours

Step-by-step explanation:

We simply need to multiply the time by the multiplier given in order to find the time it took for the smaller group

123.6 hours is the time and 1.15 is the multiplier

123.6x1.115=137.814 hours

if someone weighs five times as much as someone else and the total weight of the two people is 132 pounds how much does each person weight

Answers

Answer:

The heavier person weighs 110 pounds, and the lighter person weighs 22 pounds.

Step-by-step explanation:

Let the weight of the lighter person be 1 unit.

The weight of the heavier person will be [tex]1\times 5=5u[/tex]

Total weight: [tex]1u+5u=6u[/tex]

6 units = 132

Divide 6:

[tex]1u=\frac{132}{6}[/tex]

[tex]1u=22[/tex]

The weight of the lighter person is 22 pounds.

Weight of the heavier person [tex]= 5\times 22=110[/tex]

The weight of the heavier person is 110 pounds.

Step-by-step explanation:

someone= 5x

someone + x= 132

5x + x = 132

6X=132

x=22

One person ("someone") weighs x× 5 = 110.

the other person ("x) weighs x = 22

Answers

First, let's let's evaluate the numerator and denominator separately.

The numerator: (-2)^2(3)(4) - (-1) = 48 + 1 = 49

The denominator: (-2)^2 = 4

Now that the numerator and denominator are simplified, let's take the square root of 49/4

sqrt(49/4) = 3.5

Find the distance between the points (2,9) and (8,2)

Answers

So the distance between two points formula is :
c= the square root of (x1-x2)^2 + (y1-y2)^2

Therefore ...
(8-2)^2 + (2-9)^2
6^2 + (-7)^2
36+49= 85
Square root of 85= 9.22 approx.
Hence, the distance between the two points is 9.22

A triangle with the coordinates X(3, 2), Y(5, -1), and Z(-2, 3) is reflected across both the x- and y-axes. The coordinates after both reflections are what

Answers

Answer:

The coordinates of the reflected triangle are [tex]X'(x,y) = (-3,-2)[/tex], [tex]Y' (x,y) = (-5,1)[/tex] and [tex]Z'(x,y) = (2,-3)[/tex].

Step-by-step explanation:

Let be a point [tex](a,b)\in\mathbb{R}^{2}[/tex], reflections across x- and y-axes are represented by the following operations:

x-Axis reflection:

[tex]d = d'[/tex]

[tex]b - 0 = 0 - b'[/tex]

[tex]b' = -b[/tex]

y-Axis reflection:

[tex]d = d'[/tex]

[tex]a - 0 = 0 - a'[/tex]

[tex]a' = -a[/tex]

If we know that [tex]X (x,y) = (3,2)[/tex], [tex]Y(x,y) = (5,-1)[/tex] and [tex]Z (x,y) = (-2, 3)[/tex], the coordinates after both reflections are, respectively:

[tex]X'(x,y) = (-3,-2)[/tex]

[tex]Y' (x,y) = (-5,1)[/tex]

[tex]Z'(x,y) = (2,-3)[/tex]

The coordinates of the reflected triangle are [tex]X'(x,y) = (-3,-2)[/tex], [tex]Y' (x,y) = (-5,1)[/tex] and [tex]Z'(x,y) = (2,-3)[/tex].

The graph of y = f(x) is shown below. What are all of the real solutions of f(x)
= 0?

Answers

Answer:

x = -8, 0 and 6

Step-by-step explanation:

Graphed function in the picture,

y = f(x)

Solutions of a function are defined by the points on x-axis where the graph intersects or touches.

In the given graph, curve of the function touches the x-axis at x = -8 and crosses the x-axis at x = 0, 6

Therefore, real solutions of the function 'f' will be x = -8, 0 and 6.

Africa has influenced and has also been influenced by other continents. We can see this in its willingness to adapt to the ever-changing modern world rather than staying rooted to their static culture. This, of course, also affects their art and literature. As we know, African literature, specifically the oral type, is influenced by the sub- saharan cultures that have participated in the cultures of the United States.The traditions of Africa are veryunique because they are different from other countries and other continents. According to research Africans celebrate special events mostly through dancing. By researching thru the Internet, Oral Practices have been the most practiced tradition in Africa. African Culture tells us that they also love making artworks. African Art is another significant embodiment of the ways and means Africans communicate and propagate their ideas of life.
