D = rt
/t    /t

    D/t = r
80/16 = r
       5 = r

The Fernando family spends $800 per month on rent. If this is 15% of their monthly budget, then what is their monthly budget?
jarptica [38.1K]

Answer:

$5,333.33

Step-by-step explanation:

If the a month spent on rent is a percentage of the monthly budget of the  Fernando family, it means that the product of the percentage and the monthly budget gives the amount spent on rent.

Let the monthly budget be T (measured in $). Given that  the family spends $800 per month on rent and this is 15% of their monthly budget, it means that

15% * T = 800

T = 800/15%

= 800 * 20/3

= $5,333.33

The family's monthly budget is $5,333.33

6% of what number is 270? 4,500 450 45 4.5
Gnoma [55]

So to solve this problem, we can either do guess and check, or solve an equation.


Let's do the equation, since it will work for all problems, even when you're not given a list of possible answers.


So, to begin, let's define our unknown.

We can represent the number as "n"


So, 6 percent of "n" is equal to 270

To find a "percent" of a number, you need to multiply the number by the percentage.

So, 6 percent as a decimal is .06

This is because a percent is a fraction divided by 100 (6/100)


.6\times n=270\\\n=270\div.6\\n= 4500


The number is 4,500

Answer:

∠ZVW= 45

∠ZWV = 31

x=1

Step-by-step explanation:

Properties of a Parallelogram ( including diagonals )

Diagonals of a parallelogram bisect each other.

The diagonals are cut into two equal parts

Opposite angles are congruent

Given this information we need to find x, ∠ZVW and ∠ ZWV

First lets find x

Like stated previously diagonals cut each other into two equal parts

That being said segment WZ ≅ segment ZY

Knowing this we create an equation

2z-1=1

step 1 add 1 to each side

-1 + 1 cancels out

1 + 1 = 2

now we have 2x = 2

step 2 divide each side by 2

2x/2=x

2/2=1

we're left with x = 1

Now lets find ∠ZVW

∠ZVW and ∠ZXY happen to be opposite angles ( opposite angles are congruent )

This means that because ∠ZXY = 45 ∠ZVW also = 45

Now lets find ∠ZWV

∠ZWV and ∠XYZ happen to be opposite angles ( like stated previously, opposite angles are congruent)

So because ∠XYZ = 31 ∠ZWV also = 31
