Answer is B. $1,600

Given:
part = $400
percentage of the part = 25%
whole = ?

To get the whole or total monthly budget, simply divide the part by its corresponding percentage.

$400 / 0.25 = $1600

Other formulas to consider if other facts are given:

% of Part to the Whole = Part/Whole * 100%
                                     = 400/1600 * 100% 
                                     = 0.25 * 100%
                                     = 25%

Value of the part of a whole = Whole * % of part
                                              = 1600 * 25%/100% 
                                              = 400

The tax rate is 3.9%<br> What is the tax on 42$? <br> Round to the nearest hundredth
mafiozo [28]
To find the total price, we use this equation:
42 + 0.039(42)
We can make it simpler:
1.039(42)
Multiply:
43.638
Because we're rounding
The total price is $43.64

Look at this set of ordered pairs:
forsale [732]

Answer: Yes

If I remember correctly, I believe these ordered pairs indicate a function, as there is exactly 1 output for every input (i.e., (output, input)). If there were 2 inputs of the same number, that'd make this relation not a function.

A 120° sector of a circle has an area of 67 cm². To the nearest centimeter what is the diameter of the circle?
qaws [65]

Answer:

degree = 120°

A =67 cm²

d=?

note : diameter= 2×radius

area of a circle = πr²

67=22/7 ×r²

67×7=22r²

469=22r²

r²=469/22

r²=21.32

r=4.62

diameter=2 × radius

d= 2× 4.62

d=9.24

d=9

I hope it helps :)

Y=x+4<br> Y=2x+6<br> Solve for x and y
gladu [14]

Answer:

X = -2

y = 2

Step-by-step explanation:

Substitute y=x + 4 in the second equation to find x

x+4 = 2x + 6

subtract x from both sides

4 = x + 6

subtract 6 from both sides

-2 = x

put -2 in for x in the first equation

y= 2

Side a of the triangle is a utility pole. Henry would like to know how long the guy wire, c, should be.
jasenka [17]

We know that the pole is perpendicular to the ground

And that the length of the pole is 20 feet tall, and the base is 15 feet

Now, the guy wire is a wire that provides support to the pole by connecting the top of the pole to the ground

So this represents a right angled triangle (refer image), and the hypotenuse is the length of the guy wire

Using Pythagoras theorem, we can find out the length of the hypotenuse

⇒ Hypotenuse² = Perpendicular² + Base²

⇒ Hypotenuse² = 20² + 15²

⇒ Hypotenuse² = 400+225

⇒ Hypotenuse² = 625

⇒ Hypotenuse = √625

⇒ Hypotenuse = 25

Hence, the correct option is B  25 ft.
