Joes worked for 28 hours and earned $418.24. What did he earn per hour?

Answer:

The number that is a perfect square remains on the outside and the one that isn't, stays on the inside. For example, you can make the number 2[tex]\sqrt{3}[/tex] only when the number on the outside is a perfect square. The original number was 4, so it reduced down to 2, and the other number stayed in the radical

Answer: 0.05%

Step-by-step explanation:

Ok, you have 5 tickets with different combinations of 4 numbers of them.

Now, the total number of combinations of 4 numbers (0 to 9) can be found as:

For the first number we have 10 options.

For the second number we also have 10 options.

for the third number we also have 10 options

for the fourth number we also have 10 options.

The total number of combinations is equal to the product of the number of options for each selection, this is:

Combinations = 10*10*10*10 = 100*100 = 10,000.

So out of 10,000 possible combinations, you have 5.

Then the odds of winning is the quotient between the combinations that you have and the total number of combinations: p = 5/10,000 = 0.0005

In percentage form, this is: 0.0005*100% = 0.05%

Step-by-step explanation:

Lets say he started at 0 points and lost 30 points for each spaceship thats 3 x 30 which is 90 so he's sitting at -90 points then got 200 so thats -90 + 200 = 110

Answer:

[tex]kx-2=0[/tex]

Step-by-step explanation:

We are given that  an equation

[tex]3kx+2kx=10[/tex]

We have to find the  value of x by rearrange the equation

Subtract 10 on both sides then we get

[tex]3kx+2kx-10=0[/tex]

Now, combine like terms

[tex]5kx-10=0[/tex]

Now, taking common factor

[tex]5(kx-2)=0[/tex]

[tex]5\neq 0[/tex]

Therefore,

[tex]kx-2=0[/tex]

This is required equation to solve for x.

Answer: C) Outside the circle

Step-by-step explanation: Ok, so we know 0,0 is the center of the circle and 5,8 is on the circle, on the border. Therefore, anything more than 5,8 is outside the circle and anything less is inside the circle.

[tex]\sqrt{-15}[/tex] = -3.87

[tex]\sqrt{-74}[/tex] = -8.60

(-3.87, -8.60)

Therefore, the answer is outside the circle...pretend the rectangle is a circle...as you can see point Z will be outside the circle.

I hope this helps!

Answer: A-Inside the Circle

Step-by-step explanation: For point Z: the coordinate is (-3.9,8.6) rounded to the nearest whole and since the center of the circle is at (0,0) and a point on the circle is (5,8) then we know that every other point will be the same distance away from the circle. If (5,8) is a point on the circle then (-5,8), (-5,-8), and (5,-8) will also be points. If you plot all of these and draw a circle outline you will see that point Z falls in the circle. (I MIGHT BE WRONG but I hope this helps a little)

Answer:

6.626068 × 10-34 m2 kg / s

Step-by-step explanation:

The Planck constant, or Planck's constant, denoted h is a physical constant that is the quantum of electromagnetic action, which relates the energy carried by a photon to its frequency. A photon's energy is equal to its frequency multiplied by the Planck constant. The Planck constant is of fundamental importance in quantum mechanics, and in metrology it is the basis for the definition of the kilogram.

78=c-13

c=65

Part A-  An inequality to represent the number of coats collected by seventh grade students is, c,    C > 65

Part B- The graph of the solution on a number line, i have attached image below.

Inequalities are the comparison of mathematical expressions, whether one quantity is greater or smaller in comparison to another quantity.

We use these symbols to represent inequalities,   '>' , '<',  '≥',  '≤'

Given Information,

    The seventh grade wants to break last year's record of 78 coats collected,

    They have already collected 13 coats,

A.   They need 65 more clothes to reach at the record of 78 clothes,

     If they wants to break the last year's record they should collect more  than 65 clothes,

So, the inequality is,   C≥65

B. Graph on a number is attached in image.

Hence, the number coat must be greater than 65

Answer:

(5,-3)

Step-by-step explanation:

If point A is 6.5 on the x axis away from point M, then point B must be the same distance away. -1.5+6.5=5. If point A is 4 on the y axis away from point M then point B must also be the same distance away. 1-4=-3.

So the answer must be (5,-3)

Answer:

300 Adults 555 Children

Step-by-step explanation:

What we know:

Firstly, at 5pm there were 36 more Children (C) than Adults (A)

So.....C = A + 36

Secondly, at 12pm there were 5 x more Children and 4 x more Adults and the total was 855

So 4A + 5C = 855

——-

Now use ‘C = A + 36’ and get rid of all ‘C’ in the second equation.....

4A + 5C = 855

becomes......

4A + 5 (A + 36) = 855

Multiply the brackets (5 x A) and (5 x 36):

4A + 5A + 180 = 855

Take off 180 from both sides:

4A + 5A = 675

Therefore 9A = 675

Divide by 9:

A = 75

We know C is A + 36

C = 111

At 5 pm - A = 75 and C = 111

Therefore at 12:

There were 5 x C = 555

And 4 x A = 300

Answer:

2x-3=7

2x=10

x=5

Answer:

x=5

Step-by-step explanation:

To solve this equation, we need to find out what the variable, x, is equal to. In order to do this, we need to get x by itself. Perform the opposite of what is being done to the equation. Keep in mind that everything must be done to both sides.

2x-3=7

3 is being subtracted from 2x. The opposite of subtraction is addition. Add 3 to both sides

2x-3+3=7+3

2x=7+3

2x=10

x is being multiplied by 2. The opposite of multiplication is division . Divide both sides by 2.

2x/2=10/2

x=10/2

x=5

Answer:

see explanation

Step-by-step explanation:

(a)

Given

x² + 10x + 16

Consider the factors of the constant term (+ 16) which sum to give the coefficient of the x- term (+ 10)

The factors are + 2 and + 8, since

2 × 8 = 16 and 2 + 8 = 10, thus

x² + 10x + 16 = (x + 2)x + 8)

---------------------------------------------------

(b)

Given

x² + 7x + 12

Consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (+ 7)

The factors are + 3 and + 4, since

3 × 4 = 12 and 3 + 4 = 7, thus

x² + 7x + 12 = (x + 3)(x + 4)

------------------------------------------------------

(c)

Given

x² + 13x + 12

Consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (+ 13)

The factors are + 1 and + 12, since

1 × 12 = 12 and 1 + 12 = 13, thus

x² + 13x + 12 = (x + 1)(x + 12)
