To the nearest tenth, what is the percent of Container A that is empty after the pumping is complete?

Answer:

Step-by-step explanation:

Let,

One of the siblings age be = x

So, the other siblings ages are = x+2, x+4 and x+6

Since,

Ashley is the oldest sibling so his age is x + 6

∴ By the problem,

=> x + (x+2) + (x+4) + (x+6) = 100

=> 4x + 12 = 100

=> 4x = 100 - 12

=> 4x = 88

=> x = 22

Now,

We got the age of the youngest one that is 22 years

As,

Ashley is the oldest sibling so his age is

= 22 + 6 = 28 years

Hence,

The age of Ashley is 28 years (Ans)

Answer:

28 years old

Step-by-step explanation:

100/4 = 25

The ages are consecutive even numbers,

so add 1 to and subtract 1 from 25.

Add 3 to and subtract 3 from 25.

Ages: 22, 24, 26, 28

Ashley is the oldest: 28 years old

Answer:

Step-by-step explanation:

if you're using Del Math (yk what i'm talking about) it requires you to have a specific way of putting it.

The equation is going to be:

4.25x + 167 = 655.75

your x is going to be:

115

I hope this helps!

For the explanation hopefully, this will make sense (english isn't my first language)

So you know the number of hours: 4.25

cost of the parts: 167

total cost: 655.75

then finally the cost per hour: x

----

so now when you write your equation you're going to end up with the total number of hours (times the cost per hour) added to the cost of the parts, then the remaining will be your total cost. This is how I pictured the equation portion in my head.

for the actual solving part you subtract the cost of the parts from itself as well as the total which should leave you with: 4.25x = 488.75

then you're going to divide 4.25 from each side, as you do.

Then you have the cost of labour per hour: 115

The equation to find the cost of the labor per hour is:

167 + 4.25C = 655.75

The cost of the labor per hour is $115.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Number of hours worked = 4.25

Cost of the parts used = $167

Total cost = $655.75

Now,

We can write an equation to find the C = cost per hour.

167 + 4.25C = 655.75

Solve for C.

167 + 4.25C = 655.75

4.25C = 655.75 - 167

4.25C = 488.75

C = 115

Thus,

The cost of the labor per hour is $115.

Answer:

1111/2500

Step-by-step explanation:

The amount invested in the growth fund, income fund and money market fund is 20000, 20000 and 10000 respectively

Let the amount invested in the growth fund, income fund and money market fund be x, y and z respectively

As per the question, the company invested twice as much in the income market as in the money market

Therefore,

y = 2z

Equations will be:

x + 2z + z = 50000

12/100x + (8/100)*2z + 5/100z = 4500

Solving the equations

x + 3z = 50000

12x + 21z = 450000

Multiplying the first equation by 7 for equating

7x + 21z = 350000

12x + 21z = 450000

Equating these two we get

5x = 100000

x = 20000

Putting x = 20000 in 7x + 21z = 350000

z = 10000

2z = 20000

So, the amount invested in the growth fund, income fund and money market fund is 20000, 20000 and 10000 respectively

In mathematics, the greater than sign is a basic mathematical notation used to represent an inequality between two values.

The symbol used to denote greater inequality is “>”. It is the commonly accepted mathematical notation of two strokes of equal length that meet at an acute right angle.

A typical use of the greater than sign is to compare two values, where the first  is greater than the second, or one is greater than the other.

The greater than sign is an approximation of a closing square bracket.

Step-by-step explanation:

Slope intercept form of line equation is y = mx + b, m = slope, b = y-intercept

Slope of line perpendicular to y =m x + b will have slope   - (1/m)

4x+y=3 can be re-written as
y = -4x + 3

Slope = -4

Slope of line perpendicular to this line is - (1/-4)  = 1/4

Line equation: y = (1/4) x + b

Plug in x, y values from given point into this line equation to find b
-3 = 1/4 x 4 + b

-3 = 1 + b

-3 -1 = b

b = -4

So equation of perpendicular line is y = (1/4)x - 4

The wage of Katie before pay rise or the value of old wage is equal to $220.

What is percentage ?

Percentage is calculated by dividing the value by the total value, and then multiplying the result by 100.

It is given that the new wage is $264 as Katie gets a 20% pay rise.

Let's assume the old wage be x.

The new wage can be written as :

x + (20x / 100)

This is equal to $264.

i.e.,

(x + 20x/100) = 264

or

120x/100 = 264

Let's solve this expression to get the value of old wage.

120x = 264 × 100
