Answer:

A)15x+30=weekly income

B)8 hours

Step-by-step explanation:

15x+30= weekly income

The 15 multiplies because it says per hour

The 30 is constant because she only earns it once (per week)

15x+30=150

minus 30 from both sides

15x=120

divide by 15

x=8

Answer:

Using the height theorem:

[tex]n^2=8*4=32=>n=4\sqrt{2}[/tex]

Now we can easily use the pythagorean theorem:

[tex]8^2+(4\sqrt{2})^2 =64+32=96=>m=\sqrt{96} =4\sqrt{6}[/tex]

Answer:

first one is correct and second also but in third it is incorrect and fourth is correct so C is incorrect

Answer:

C

Step-by-step explanation:

the quotient of a number means n divided by or n/

and twelve plus four, means that is the second part of the expression

n/ 12+4 would be correct instead of 12/n +4

Answer:

The probability that the system works is 87.75%.

Step-by-step explanation:

Given that a system consists of two independent components in parallel, and the system works if at least one of the components works, if each component works with probability 0.65, to determine what is the probability that the system works the following calculation must be performed:

1 - 0.65 = 0.35

0.35 x 0.35 = X

0.1225 = X

1 - 0.1225 = 0.8775

Therefore, the probability that the system works is 87.75%.

Answer:

790

Step-by-step explanation:

Substitute the value (x = 5) into the following expression, replace the parameter (x) with the value (5) wherever the parameter (x) is present,

[tex]6x^3+8x[/tex]

[tex]6(5)^3+8(5)[/tex]

Simplify use the order of operations. The order to operations is the system of steps that one uses to solve an equation, these steps are the following,

1. Parenthesis

2. Exponents or Radicals

3. Multiplication or Division

4. Addition or subtraction

Quick note, a number to any exponent is equal to the number times itself the number of times the exponent indicates.

Use these steps to simplify the given expression,

[tex]6(5)^3+8(5)\\\\=6(125)+8(5)\\\\=750+40\\\\=790[/tex]

Answer:

a) 4^6

Answer:

  $705.78

Step-by-step explanation:

Put the given numbers in the formula and do the arithmetic.

  P = $300, r = 0.13, n = 1, t = 7

__

  A = $300.00(1 + 0.13/1)^(1·7)

  A = $300·(1.13^7) ≈ $300·2.35260548

  A = $705.78

There will be $705.78 in the account after 7 years.

Answer: 64units³

Step-by-step explanation:

The volume of a cube will be gotten by multiplying the value of its side thrice. This means that for example if the cube has a side of xcm, the volume will be:

= x × x × x

= x³

In this case, since the cube has a side of 4 units, the volume will be:

Volume of cube = 4³

Volume of cube = 4 × 4 × 4 = 64unit³

Answer:

Hello, Here is your answer.

Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.

Answer:

Step-by-step explanation:

By drawing a net, you can see each face of the prism. You can find the areas of each face and then add them together to find the total surface area.

Answer:

193.45

Step-by-step explanation:

The discount price is $69.4428.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

A garden store purchased a lawn mower and marked it up 160% from the original cost of $82.67.

So, the Marked up amount

= 160 % of 82.67

= $132. 272

and, then 10% discount

=  10% of 132.272

= 13.2272

so, the discount price = 82.67 - 13.2272 = $69.4428

Answer:

2(1 - x)

Step-by-step explanation:

Twice the difference of 1 and a number

a number = x

The difference of 1 and a number is expressed as :

1 - x

Twice this difference, means the difference of (1-x) multiplied by 2

2 * (1 - x) = 2(1 - x)

Answer:

a. Center: (-15, 9), Radius: 5

Step-by-step explanation:

Equation of a circle:

The equation of a circle of center [tex](x_0, y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

In this question, we have that:

[tex](x + 15)^2 + (y - 9)^2 = 25[/tex]

Comparing both equations:

[tex]x - x_0 = x + 15[/tex]

[tex]x_0 = -15[/tex]

And

[tex]y - y_0 = y - 9[/tex]

[tex]y_0 = 9[/tex]

The center is [tex](-15,9)[/tex].

For the radius:

[tex]r^2 = 25[/tex]

[tex]r = \sqrt{25} = 5[/tex]

The correct answer is given by option a.

Answer:

z=26

Step-by-step explanation:

4z-8+3z+6=180

7z-2=180

7z=182

z=26

Answer:

z=26

Step-by-step explanation:

add the 2 equation together to equal 180

4z-8+3z+6

combine like terms

7z-2=180

add 2 to both sides

7z=182

divide by 7 to isolate z

z=26

Answer:

[tex]MP = 12[/tex]

Step-by-step explanation:

Given

[tex]LM = (3x + 1), MN = (4x -3), NP = (6x - 5)[/tex]

[tex]LM = NP[/tex]

Required

Find MP

We have:

[tex]LM = NP[/tex]

This gives:

[tex]3x + 1 = 6x - 5[/tex]

Collect like terms

[tex]3x - 6x = -1-5[/tex]

[tex]-3x = -6[/tex]

Solve for x

[tex]x = 2[/tex]

MP is calculated as:

[tex]MP = MN + NP[/tex]

[tex]MP = 4x - 3 + 6x - 5[/tex]

Collect like terms

[tex]MP = 4x + 6x - 3 - 5[/tex]

[tex]MP = 10x - 8[/tex]

Substitute [tex]x=2[/tex]

[tex]MP = 10*2 - 8[/tex]

[tex]MP = 20 - 8[/tex]

[tex]MP = 12[/tex]
