The value of this expression is $3 x 10^{6}$

In order to find this, you divide each term separately. First we'll start with the numbers in the front.

$\frac{4.8}{1.6} = 3$

Now that we have the first number, we look to the 10s and the powers they are raised to. Since we are looking at powers of the same number, we can use the properties of exponents to simply subtract the numbers they are raised to.

$\frac{10^{9}}{10^{3}} = 10^{6}$

Then we put the two back together for the final answer.

$3 x 10^{6}$

Subtract 4 ounces from 5 pounds. 3 lb, 12oz. 3 lb, 8oz. 4 lb, 12oz. Or 5 lb, 6oz?

Answer:

This was already asked

Step-by-step explanation:

Answer is 4 lb.,12 oz. As one pound has 16 ounces. When we convert the given 5 lb. into ounces we multiply it by 16. 5 lb = 5 x 16 oz 5 lb = 80 oz When we subtract 4 oz from 80 oz We get 80 - 4 = 76 oz Which is 64 oz + 12 oz (16 x 4) oz + 12 oz Which will be 4 lb. + 12 oz So the answer will be 4 lb., 12 oz.

Calculate m∠ADC. Round to the nearest thousandth.

stira [4]

Answer: $54.508^{\circ}$

Step-by-step explanation:

Let the angle ADC = x degree

Since, By the given diagram, In triangle BDC,

$\frac{BC}{DC} = tan27^{\circ}$

⇒ $\frac{BC}{19.6} = tan27^{\circ}$

⇒ $BC = 19.6\times tan 27^{\circ}$

⇒ $BC = 9.98669881009$

Now, In triangle ADC,

$tan x =\frac{AC}{DC}$

⇒ $tan x =\frac{AB+BC}{DC}$

⇒ $tan x =\frac{17.5+9.98669881009}{19.6}$

⇒ $tan x =\frac{27.4866988101}{19.6}$

⇒ $tan x =1.40238259235$

⇒ $x = 54.508389368\text{ degree} \approx 54.508^{\circ}$

Answer:

26 ft^2

Step-by-step explanation:

Let us imagine a rectangle around this figure, provided a rectangle with dimensions 5 feet by 7 feet. If we were to subtract the non - shaded region in this rectangle from the rectangle's area itself, it would save as some time to solve for the area of the shaded region;

Area of Outer Rectangle ⇒ 5 * 7 = 35 ft^2,

Now this non - shaded region is composed of a triangle and a rectangle, the triangle having dimensions 3 by 2 feet, the rectangle being 2 by 3 feet consecutively;

Area of triangle ⇒ 1/2 * base * height = 1/2 * 3 * 2 = 3 ft^2,

Area of rectangle ⇒ length * width = 2 * 3 = 6 ft^2

Thus the area of the shaded region is: 35 - 3 - 6 = 26 ft^2;

Answer: 26 ft^2

Luna mixes 3/4 cup of orange juice with 3/8 cup of cranberry juice. She gives 5/8 cup of the juice to mags. How much is left in

Hunter-Best [27]

3/4 = 4/8 (converting fractions )

4/8 + 3/8 = 9/8 cups of juice altogether

9/8 - 5/8 = 4/8 (taking away mags' amount )

4/8 is equivalent to a 1/2 so she still has 1/2 a cup of juice left.
