If 4 workers take 900 hours to finish a project, how long will it take 8 workers to complete the same project?

Answers

Answer 1

Answer: 350

Step-by-step explanation: If you multiply the amount of workers by two, then you divide the amount of time by two, and vice versa. So, in other words, whatever number you multiply the workers by, divide the time by that same number. I hope this helps!

Answers

answer:

it should be the graph on the top right!

The graph of the parent function f(x) = 0.75ˣ + 1 is shown in figure.

What is Function?

A relation between a set of inputs having one output each is called a function.

Given that;

The parent function is,

⇒ f(x) = 0.75ˣ + 1

Now,

Since, The parent function is,

⇒ f(x) = 0.75ˣ + 1

Hence, The points on the function are (0, 2) and (1, 1.75).

Thus, The graph of the parent function is given in option 2.

Variable on both sides
John will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $57.96 and costs an additional $0.12 per mile driven.
The second plan has an initial fee of $47.96 and costs an additional $0.16 per mile driven. How many miles would John need to drive for the two plans to cost
the same?
II miles
Х
?

Answers

So for starts we can go 0.16 x 63 miles = 10.04 so the total for the second plan would be $58 with driving 63 miles. and for the first plan would be 0.12 divided by 3 would be 0.04 so we add them together and we get $58 with driving a 3rd of a mile.

Overall:

1st plan: $58 with driving a 3rd of a mile.

2nd plan: $58 with driving 63 miles.

solve for the variable.

3(2x-4)+6=30

x=___

Answers

Answer:

x = 6

Step-by-step explanation:

Use distributive property: a(b + c) = a*b + a*c

3(2x - 4) + 6= 30

3*2x - 3*4 + 6 = 30

6x - 12 + 6 = 30

6x - 6 = 30

     6x = 30+ 6

     6x = 36

       x = 36/6

x = 6

Answer:

x = 6

Step-by-step explanation:

Simplify 3(2x-4) first: 3 (2x) 3(-4) =

6x - 12+6 = 30

Combine like terms: -12 + 6 = -6

6x - 6 = 30

Add 6 to both sides: 6x = 36

Divide both sides by 6: x = 6

CHECK:

3( 2(6) - 4) +6 = 30

3 (12-4) +6 = 30

3(8) +6 = 30

24+ 6 = 30

30 = 30

2 Hiroaki says that a constant of proportionality must be a whole number and

cannot be a fraction or a decimal. Explain why Hiroaki is incorrect.

Answers

Given:

Hiroaki says that a constant of proportionality must be a whole number and  cannot be a fraction or a decimal.

To find:

The explanation, why Hiroaki is incorrect.

Solution:

If y is directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

[tex]\dfrac{y}{x}=k[/tex]

where, k is the constant of proportionality.

It means, the constant of proportionality is the ratio of two directly proportional variables.

So, constant of proportionality can be any real.

Thus, the statement that a constant of proportionality must be a whole number and  cannot be a fraction or a decimal is incorrect.

Hence, Hiroaki is incorrect because constant of proportionality can be any real.

Help me to do this problem System by sustitution.
4) y = -3x - 7
-6x - 2y = 14​

Answers

Answer:

The system of equations has infinite solutions

Step-by-step explanation:

y = -3x - 7 ⇒ (1)

-6x - 2y = 14 ⇒ (2)

→ Substitute y in equation (2) by equation (1)

∴ -6x - 2(-3x - 7) = 14

→ Simplify the left side

∵ -6x - 2(-3x) - 2(-7) = 14

-6x + 6x + 14 = 14

→ Add the like terms in the left side

∵ (-6x + 6x) + 14 = 14

∴ 0 + 14 = 14

14 = 14

∵ The variable is disappeared and the two sides of the equation equal

∴ The equation has many solutions

→ That means x and y can be any numbers

The system of equations has infinite solutions

Write an equation of the parabola in vertex from y=a(x-h)^2 +k that passes through (-7,-15) and has vertex (-5,9).

Answers

Answer:

Step-by-step explanation:

We have the work form of the equation, and we also have values for x, y, h, and k. All we need to do is fill those in and solve for a:

[tex]-15=a(-7-(-5))^2+9[/tex]

Let's clean that up a bit.

[tex]-15=a(-2)^2+9[/tex] and

-15 = 4a + 9 and

-24 = 4a so

a = -6

Now we'll fill in the a value along with the h and k to get
