Jack can fill buckets of water four times fast as his sister Jill. They have to fill 400 buckets of
water for their village located at the bottom of a hill. Working together, Jack and Jill can complete
the job in six hours.
30. How many hours will it take Jack if he works alone?

Answers

Answer 1

Answer:

1.5 hour

Step-by-step explanation:

You divide 6 by 4.

Answer 2

Answer:

7.2 hrs

Step-by-step explanation:

Jack does 4/5 of the work in 6 hrs. He still needs to do 1/5 more if he's doing it by himself. 1/5 of 6 = 1.2 and 1.2 + 6 = 7.2 hrs

LO bisects &NLM, LM= 22, NO = 6, and LN= 14. What is the approximate value of x?

x= 3.8

x=9.4

x=51.3

x= 73.3

Answers

Answer:

9.4

Step-by-step explanation:

Given :

LM= 22, NO = 6, and LN= 14 ; MO = x

Since O bisects the triangle ;

LN / NO = LM / MO

14 / 6 = 22 / x

Cross multiply :

14 * x = 22 * 6

14x = 132

Divide both sides by 14

14x/14 = 132 / 14

x = 9.428

x = 9.4 ( 1 decimal place)

Find the maximum value of y = -x^2 + 6x + 5​

Answers

the answer is C, you use the formula x=-b/2a

Answer:

D

Step-by-step explanation:

The maximum value is the y- coordinate of the vertex

Given a quadratic in standard form , y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = - x² + 6x + 5 ← is in standard form

with a = - 1 and b = 6 , then x- coordinate of vertex is

x = - [tex]\frac{6}{-2}[/tex] = 3

Substitute x = 3 into the function for y- coordinate of vertex

y = - 3² + 6(3) + 5 = - 9 + 18 + 5 = 14

maximum value is 14 → D

a dog is leashed 48 feet to the corner of a house.howmuch running area does the dog have?​

Answers

Answer:

The dog has 1357.5 square feet of running space.

Step-by-step explanation:

48 feet is the diameter of the circle in which the dog can run, minus 1/4 of the total circle (assuming the dog can not run through walls).

The formula of how to find the area of a circle is...

A =  π r²

A stands for area, pi(π) is 3.14, and r means radius.

Radius is half of the diameter, so the radius would be 24 feet. Let's plug those numbers into the formula:

A = π x 24²

A = π x 576

A = 1809.56 square feet

Now, we have to subtract 1/4 of 1810 (rounded up).

1810 times 0.75 = 1357.5 feet.

I hope this helps you! :-)

On the same day, Parker’s friend, Peggy, was charged $5 for 1 1/2 lb. of gummy candy. Explain in terms of the graph why this must be a mistake.

Answers

Answer:

After a quick online search, I've found that the complete question is:

a) Parker paid $4.50 for three pounds of gummy candy. Assuming each pound of gummy candy costs  the same amount, complete the table of values representing the cost of gummy candy in pounds.

Then we want to graph the points, and then comes our question:

c) On the same day, Parker’s friend, Peggy, was charged $5 for 1 1/2 lb. of gummy candy. Explain in terms of the graph why this must be a mistake.

So first, we know that this is a proportional relationship (each pound of candy costs the same)

And 0 pounds of candy should cost $0.

Then the relation between y (price) and x (number of lb) is:

y = k*lb

where k is the cost per lb.

Knowing that Parker paid $4.50 for three pounds of gummy candy, the relation is:

$4.50 = k*3lb

($4.50/3lb) = k = $1.50/lb

Then the linear relation is:

y = ($1.50/lb)*x

Now, in this question we can see that Parker's friend was charged $5 for ( 1 and 1/2) lb of candy.

If we replace those values in the equation, we get:

$5 = ($1.50/lb)*(1 + 1/2)lb = $2.25

This equation is false, then, in terms of the graph, the point ( (1 and 1/2)lb, $5) does not belong on the graph that you found in the previous points.

los monitores que están fabricando estan apoyados en un soporte triangular, si el monitor mide 50 cm y debe tener una altura de 30cm ¿cuanto mide la base del soportre?

Answers

Answer:

La base del soporte mide 58.3 cm.

Step-by-step explanation:

Dado que los monitores que están fabricando están apoyados en un soporte triangular, si el monitor mide 50 cm y debe tener una altura de 30cm, para determinar cuánto mide la base del soporte se debe realizar el siguiente cálculo utilizando el teorema pitagórico:

50^2 + 30^2 = X^2

2,500 + 900 = X^2

3,400 = X^2

√3,400 = X

58.30 = X

Por lo tanto, la base del soporte mide 58.3 centímetros.

The volume of prism is, [tex]180^{3}[/tex]

Step-by-step explanation:

From the given figure, we have

The length of the triangular prism is 6 units.

Since in the triangular cross-section we have the base (b) equals 5 units and the height (h) equals 12 units.

Using Volume of triangular prism formula: - A triangular prism whose length is l units, and whose triangular cross-section has base b units and height h units, then,

Volume(V) of the triangular prism in the cubic unit is given by;

[tex]V=\frac{1}{2}bhl[/tex]

Putting the values of [tex]l=6[/tex] unit, b=5 unit and h = 12 unit.

⇒  V = 1/2 × 5 × 6 × 12

on solving we get;

[tex]V=180^{3}[/tex]

therefore, the volume of the prism is [tex]180^{3}[/tex].

The point which is located at (2,0) is A, the correct option is 1.

How to find the function which is used to make graph?

There are many tools we can use to find the information of the relation which was used to form the graph.

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.

If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.

We are given that;

The coordinates = (2,0)

Now,

The coordinates of point A = (2,0)

The coordinates of point B = (0,2)

The coordinates of point C = (-2,0)

The coordinates of point D = (0,-2)

Therefore, by the graph the answer will be Point A.
