Answer:

$7.80 an hour

Step-by-step explanation:

$31.20/4 = 7.8
$54.60/7 = 7.8

Answer:

$7.80 per hour

Step-by-step explanation:

I know this equation might seem a bit complicated, but it's actually really simple. Just divide.

$31.20/4 = $7.80

Now we just have to make sure the second one matches.

$54.60/7 = $7.80

Since they both match, the hourly rate of pay is $7.80.

Seventy percent of fifty (50) is 35

The percent or percentage of a number is the division of the number with 100.

From the given information, we are being told that 70% of a number is 35.

It means that:

70% of x = 35

[tex]\mathbf{(\dfrac{70}{100})x = 35}[/tex]

0.7x = 35

Divide both sides by 0.7

x = 35/0.7

x = 50

Answer:

$20 for each stuffed animal

Step-by-step explanation:

[] The original price is $25, but it is 20% off.

100% - 20% = 80%

[] Now we can find 80% of $25.

-> First, 80% divided by 100 becomes 0.8, a decimal we can work with

25 * 0.8 = 20

Answer: the top right

Step-by-step explanation:

Given :-

To Find :-

Solution :-

According to the question ,

→ In 20days 12 workers can do a piece of work.

→ In 1day 12*20 workers can do that work

( Less days , more workers )

→ In 16 days 12*20/16 = 15 workers can do the work.

So 15 -12 = 3 workers should be added to complete the work.

Hence the required answer is 3 .

Answer:

Distance = -7.6

Step-by-step explanation:

Using Distance Formula, √((x2-x1)^2 + (y2-y1)^2)

√((-7 - 0))^2 + (-3 - 0)^2) = 7.6

Answer:

A. {x,y}={-2,-3}

// Solve equation [2] for the variable  x

 [2]    x = 2y + 4

// Plug this in for variable  x  in equation [1]

  [1]    (2y+4) - y = 1

  [1]    y = -3

// Solve equation [1] for the variable  y

  [1]    y = - 3

// By now we know this much :

   x = 2y+4

   y = -3

// Use the  y  value to solve for  x

x = 2(-3)+4 = -2

B.   [1]           3x=3y-6

 [2]           y=x+2

Equations Simplified or Rearranged :

  [1]    3x - 3y = -6

  [2]    -x + y = 2

Solve by Substitution :

// Solve equation [2] for the variable  y

 [2]    y = x + 2

// Plug this in for variable  y  in equation [1]

  [1]    3x - 3•(x +2) = -6

  [1]    0 = 0 =>  Infinitely many solutions

  [2]    0 = 0 =>  Infinitely many solutions

Answer:

Step-by-step explanation:

a) y = -1/4x    --------------(I)

x + 2y = 4 -----------------(II)

Substitute y = (-1/4)x in equation (I)

[tex]x + 2*\dfrac{-1}{4}x=4\\\\\\x -\dfrac{1}{2}x=4\\\\Multiply \ the \ entire \ equation \ by \ 2 \\\\2x -x = 8\\\\x=8[/tex]

[tex]Substitute \ x = 8 \ in \ equation \ (I)\\\\y=\dfrac{-1}{4}*8\\\\\\y = -2[/tex]

Answer: x = 8  ; y = -2

b) y = -x - 2 --------------(i)

   3x + 3y = 6   -----------(ii)

Divide equation (ii) by m

x + y = 2

  y = -x + 2  ----(iii)

From (i) and (iii), it shows that these lines have same slope. So, they are parallel lines

Answer: No solution

3) -8x + 2y =4

            2y = 8x + 4

Divide the entire equation by 2

             y = 4x + 2 -------------(i)

            y = 4x + 2 ----------------(ii)

From (i) and (ii), we come to know that these lines coincide.So, they have infinite solutions.

The answer is 345

Step-by-step explanation:

The lateral surface area of a cylinder can be defined as the surface area of all of the sides of the cylinder excluding its base and top is calculated using lateral_surface_area = 2* pi * Radius * Height. To calculate Lateral Surface Area of a Cylinder, you need Radius (r) & Height (h).

but instead, will be using 3.14

2*3.14*4.9*11.2

6.28*54.88 = 344.6464

344.6464 rounded to the nearest whole number is:

Answer:

x ≤ 4

Step-by-step explanation:

x ≤ 4

A closed circle means ≤ or ≥

An open circle means < or >

As the shaded area is to the left of 4,   x ≤ 4

A function is a mapping from domain to range. The domain of the function [tex]y = \sqrt{x+6} - 7[/tex] is given as: [tex]x \geq -6[/tex] or [tex]x \in [-6, \infty)[/tex] (both are same)

One method of finding the domain of a function is to start by finding the values for which it isn't defined.

Assuming that the function  [tex]y = \sqrt{x+6} - 7[/tex] is defined for only real numbers, then, as we know that:

[tex]\sqrt{x}[/tex] exists only if x is non-negative, which means for  [tex]\sqrt{x+6}[/tex] to be defined, we need

[tex]x + 6 \geq 0\\x \geq -6[/tex]

No other way is there for the function to be non-existing.

Thus, the values on which the function is defined is all real numbers bigger or equal to -6. This is the domain of the given function.

Thus,  the domain of the function [tex]y = \sqrt{x+6} - 7[/tex] is given as: [tex]x \geq -6[/tex] or [tex]x \in [-6, \infty)[/tex] (both are same)

Answer:

Surprisingly the answer is 5,005.

Basically this is asking "in how many ways can you choose 9 things from a set of 15 things".

You will need to use the formula found at the top of this page:

https://www.1728.org/combinat.htm

Filling in the formula in which 'r' = 9 and n = '15'

combinations = n! / (r! * (n-r))!

combinations = 15*14*13*12*11*10 * 9! / (9! * 6!)

combinations = 15*14*13*12*11*10 / 6*5*4*3*2*1

combinations = 14 * 13 * 11 * 10 / 4  

= 14 * 13 * 11 * 2.5

= 5,005
