This is a two step problem. First, you need to find the difference (or increase) in the rent using subtraction.

616-560 = $56 increase

Now we need to figure what percent 56 is to the original amount (560)

We voice it like this:

56 is to 560 as x is to 100.

The equation looks like this:

56/560 - x/100

Cross multiply to cancel out the denominators.

56 x 100 = 560 x

5600 = 560 x

x = 10 percent.

Check it!

What is 10 percent of 560?

560 x .1 = $56

Was that your increase? ... yes.

An empty can weighs 30 grams. The weight of the same can filled with liquid is 47.3 grams. Which equation could be used to find

Alika [10]

Answer:

w = y - x is the equation to find w

Where,

w = Weight of the liquid

x = Weight of the empty can

y = Weight of the can with liquid

Step-by-step explanation:

Let

Weight of the empty can = x

Weight of the liquid = w

Weight of the can with liquid = x + w = y

x= 30 grams

w = ?

y= 47.3 grams

y = x + w

w = y - x

= 47.3 - 30

= 17.3

w= 17.3 grams

Therefore, the weight of the liquid is 17 .3 grams

The table and the graph show the relationship between the edge length, x, of a cube and its surface area, y. Is the relation a f

d1i1m1o1n [39]

Answer:

Yes, the relationship between x and y is a non-linear function.

Step-by-step explanation:

Given the table

Edge Length, x Surface Area, y

1 6

2 24

3 54

4 96

The table values clearly represent a function, because each input value has one and only one output value. i.e. there is no repetition of x values.

Also from the table values and the graph, it is clear that the function is not a linear function, because the graph is not a straight line. Also, In a cubic function, the highest power over the x variable(s) is 3. So, it is not a linear function.

Hence, we conclude that Yes, the relationship between x and y is a non-linear function.

Therefore, the 'last option' is correct.

Leona purchased a $1,000 bond having a quoted price of 99.875. She had to pay a 5.5% brokerage fee (of the selling price). What

Zina [86]

Answer:

The total cost of the bond is none of the given choices.

Step-by-step explanation:

The selling price of a $1000 bond = $99.875

The brokerage fee = 5.5 %

Now, 5.5% of $99.875 = $\frac{5.5}{100} \times 99.875 = 5.493$

So, the brokerage fee = $5.493

Now, to find out the total cost of the bond:

Total Cost = The selling Price + Brokerage Price

= $99.875 + $5.493

= $105.368

or, the total price of the $1000 bond is $ 105.368.

Hence, the total cost of the bond is none of the given choices.

Ray feeds his dog 0.12 kilogram of dry dog food each

Julli [10]

Answer:

The smallest bag that has enough food to feed his bag for one month

= 3.6 kilogram

Step-by-step explanation:

The quantity of dry food Ray feeds his dog = 0.12 kilogram

So the quantity of food he feeds his dog in one month

= 0.12 × 30 ∵ since 1 month = 30 days

= 3.6 kilogram

The smallest bag that has enough food to feed his bag for one month

= 3.6 kilogram

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. David invested $220

S_A_V [24]

Answer:

The answer is 23 years.

Step-by-step explanation:

We will use the formula :

$A=P(1+r)^{t}$

Here P = 220

r = 3%

A = 400

Putting these values in the formula we get,

$400=200(1+0.03)^{t}$

$2=1.03^{t}$

Taking log on both sides,

ln(1.03)t=ln 2

$t=\frac{ln(2)}{ln(1.03)}$

t=23.44 or rounding to nearest, t=23 years

The graph of the function can be shown as below.
