Answer:

No, it doesn't matter. In the end, both will have the answer of 4. Anything inside the absolute value is positive. So if |-5-(-9)| is |4|, then the answer is 4. If |-9-(-5)| is |-4|, then the negative four will turn into a positive four because it is inside the absolute value.

So in the end, both answers are 4 and it doesn't matter in which order the equation is set.

s344n2d4d5 [400]

Answer:

1. 7/9

2. 7/16

3. 3/7

4. 123/125

Step-by-step explanation:

1. Simplify the following:

2/9 + 5/9

2/9 + 5/9 = (2 + 5)/9:

(2 + 5)/9

2 + 5 = 7:

Answer: 7/9

_________________________

2. Simplify the following:

3/4 - 5/16

Put 3/4 - 5/16 over the common denominator 16. 3/4 - 5/16 = (4×3)/16 - 5/16:

(4×3)/16 - 5/16

4×3 = 12:

12/16 - 5/16

12/16 - 5/16 = (12 - 5)/16:

(12 - 5)/16

12 - 5 = 7:

Answer: 7/16

3. Simplify the following:

6/7×1/2

6/7×1/2 = 6/(7×2):

6/(7×2)

6/2 = (2×3)/2 = 3:

Answer: 3/7

__________________________________________________

4. Rewrite the decimal number as a fraction with 1 in the denominator

0.984=0.984/1

Multiply to remove 3 decimal places. Here, you multiply top and bottom by 10^3 = 1000

(0.984/1)×(1000/1000)= 984/1000

Find the Greatest Common Factor (GCF) of 984 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 8,

(984/8) = 123

(1000/8) = 125

Therefore

X=123/125

In conclusion,

Answer: 0.984=123/125

A basketball with a diameter of 9.5 in. is placed in a cubic box with sides 12 in. long. How many cubic inches of packing foam a

elena55 [62]

Answer:

1279.3 cubic inches (Rounded to the nearest tenth)

Step-by-step explanation:

Side of a cubic box = 12 inches

volume of cubic box = $side^3$ (since side is equal to 12 inches)

= $12^3$ = 1,728 cubic inches

It means that box can be filled with 1,728 cubic inches of any material

____________________________________________________

But, it is given that it has one basketball placed in it.

hence we need to find the volume of basketball .

Since basket ball is spherical in shape

formula to calculate its volume will be same as that of formula to calculate volume of sphere

volume of sphere = $(4/3 ) \pi r^3\\$ where r is the radius of sphere

radius of basketball = diameter/2 = 9.5/2 in = 4.75 inches

therefore volume of basket ball is given by

volume of basketball = $(4/3 ) \pi r^3\\\\\\=>(4/3 ) \3.14* 4.75^3\\\\\\= 448.693 \ cubic \ inches$

___________________________________________

In box with volume 1,728 cubic inches,, 448.693 cubic inches is occupied by basketball.

It means rest is empty which can be filled with foam.

To calculate the empty space, we subtract volume of basket ball from volume of box

volume of empty space = volume of box - volume of basket

= 1728 - 448.693 = 1279.307 cubic inches

1279.307 cubic inches in nearest tenth will be 1279.3 cubic inches.

Hence, 1279.3 cubic inches of foam are needed to fill the rest of the box

Jason and Alison are hiking in the woods when they spot a rare owl in a tree. Jason stops and measures an angle of elevation of

Shalnov [3]

Answer:

$Owl= 67.14ft$

Step-by-step explanation:

See comment for complete question.

The given information is represented in the attached figure.

First convert 22°8'6'' and 30° 40’ 30” to degrees

$22^{\circ} 8'6'' = 22 + \frac{8}{60} + \frac{6}{3600}$

$22^{\circ} 8'6'' = 22.135^{\circ}$

$30^{\circ} 40'30'' = 30 + \frac{40}{60} + \frac{30}{3600}$

$30^{\circ} 40'30'' = 30.675^{\circ}$

Considering Jason's position:

$tan(22.135^{\circ}) = \frac{H}{x + 48}$

Where x = distance between the tree and Alison

Make H the subject

$H = (x + 48)tan(22.135^{\circ})$

Considering Alison's position

$tan(30.675^{\circ}) = \frac{H}{x}$

Make H the subject

$H = xtan(30.675^{\circ})$

$H = H$

$(x + 48)tan(22.135^{\circ}) = xtan(30.675^{\circ})$

$(x + 48) *0.4068 = x* 0.5932$

Open bracket

$x *0.4068 + 48 *0.4068 = 0.5932x$

$0.4068x + 19.5264 = 0.5932x$

Collect Like Terms

$-0.5932x+0.4068x = -19.5264$

$-0.1864x = -19.5264$

$0.1864x = 19.5264$

Make x the subject

$x = \frac{19.5264}{0.1864}$

$x = 104.76$

Substitute 104.76 for x in $H = xtan(30.675^{\circ})$

$H = 104.76 * tan(30.675^{\circ})$

$H = 104.76 * 0.5932$

$H = 62.14$

The above represents the height of the tree.

The height of the owl is:

$Owl= H + 5$

$Owl= 62.14 + 5$

$Owl= 67.14ft$
