Answer:

4.2

Step-by-step explanation:

The tenth spot would be the number right after the decimal. The number in the hundredths spot is the one that determines what happens to the number in the tenths spot.

If the number in the hundredths is 5 or more, you would round the number in the tenths spot up one.

If the number in the hundredths spot is 4 or less, you would keep the same number in the tenths spot.

Since the number in the hundredths spot is 3, you would leave the number in the tenths place the same (2).

Marla bought one necklace and two bracelets for $67.50. Use the following information to determine the amount she paid for each

alexdok [17]

Ooh, scary math

n+2b=67.5
n=27
27+2b=67.5
minus 27 both sides
2b=40.50
divide both sides by 2
b=20.25

a bracelet costs $20.25

A square is cut from a rectangle. The side length of the square is half of the unknown width w. The area of the shaded region is

Virty [35]

Answer:

See below

Step-by-step explanation:

The side of the square is w/2, then its area is:

A = (w/2)² = w²/4

The shaded area is the difference of areas of the rectangle and the square:

14w - w²/4 = 84

This can be simplified:

56w - w² = 336
w² - 56w + 336 = 0

Write the expression 44(4–7)(4) using a single exponent.

Ghella [55]

<h3>The given expression as single exponent is:</h3>

$4^4 \times 4^{-7} \times 4 = 4^{-2}$

Solution:

Given expression is:

$4^4 \times 4^{-7} \times 4$

In exponents,

When the base is same, exponents can be added

Which means,

$a^m \times a^n = a^{m+n}$

Therefore,

$4^4 \times 4^{-7} \times 4 = 4^{4-7+1}\\\\Simplify\\\\4^4 \times 4^{-7} \times 4 = 4^{-3+1} \\\\4^4 \times 4^{-7} \times 4 = 4^{-2}$

Thus the given expression as single exponent is:

$4^4 \times 4^{-7} \times 4 = 4^{-2}$
