Someone please help me answer this

The value of vector |q-r| = 18

The Cosine Rule can be used in any triangle relate all three sides to one angle.

Let OA =|q|

OB = |r|

BA = |q|-|r|

Hence ∠AOB = 45°+(360°-300)

∠AOB = 45°+60°

∠AOB = 105°

Given  |q| = 5,  |r| = 16

Now using cosine rule

|q-r| = √(16)²+(5)²-2×16×5×cos105°

|q-r| = 18

Answer:

3/19

Step-by-step explanation:

First, make 4 a fraction. Now, flip 4/1 to 1/4 for the following instruction: Do 12/19 x 1/4 = 12/76. Now divide both the denominator and numerator by 4 which equals 3/19.

Answer:  3/19 gallon

Step-by-step explanation:  1/4 of 12 is 3.

Just keep the denominator.

[tex]x = 5.5[/tex]

Answer:

x = 54

y = 47.5

Step-by-step explanation:

If two lines p and q are parallel and line r is a transversal intersecting these lines at two different points,

(x + 56)° = (2x + 2)° [corresponding angles]

2x - x = 56 - 2

x = 54

Similarly, lines r and s are parallel lines and q is a transversal line intersecting these lines,

(y + 7)° + (3y - 17)°= 180° [Consecutive exterior angles]

4y - 10 = 180

4y = 190

y = 47.5

Answer:

x>14

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

-4>-2x+24

Step 2: Flip the equation.

-2x+24<-4

Step 3: Subtract 24 from both sides.

-2x+24-24<-4-24

-2x<-28

Step 4: Divide both sides by -2.

-2x-2<-28-2

x>14

Answer:

x = 22

Step-by-step explanation:

If l and m are parallel, then

(2x + 60) and 130° are same- side interior angles and are supplementary, thus

2x + 6 + 130 = 180 , simplify

2x + 136 = 180 ( subtract 136 from both sides )

2x = 44 ( divide both sides by 2 )

x = 22

Problem 9

1 liter = 1000 cubic cm

The base of the carton has area 50 cm^2, or 50 square cm.

Let A = 50 to represent the area.

The height h is unknown. It multiplies with the value of A to get the volume

V = A*h

1000 = 50*h

50h = 1000

h = 1000/50

h = 20

Answer: The carton is 20 cm tall

Problem 10

Part (a)

This 3D configuration will allow us to fit 2*3*2 = 12 dice in total

Answer: 12 dice will fit

----------------------------

Part (b)

The box has volume 5*4*7 = 140 cubic cm

Each die has volume 2*2*2 = 8 cubic cm. There are 12 dice we can fit in, so 12*8 = 96 cubic cm is the amount of volume taken up by the dice

We have 140-96 = 44 cubic cm of empty air left over.

Answer: 44 cubic cm

=======================================================

Problem 11

1 liter = 1000 cubic cm

8 liters = 8000 cubic cm

So he has 8000 cubic cm of soil

The volume of the cube is

(22.5)^3 = (22.5)*(22.5)*(22.5) = 11,390.625 cubic cm

He won't have enough soil to completely fill the cube shaped planter

We can be able to determine this by recalling that 2^3 = 8, so (20)^3 = 8000. Meaning that a cube shaped planter of sides 20 cm will lead to a volume of 8000 cubic cm. Anything over 20 cm will lead to a larger volume.

So in short, spotting the 22.5 being larger than 20 is a quick way to know that the planter has more volume compared to the amount of soil he has.

Answer: He won't have enough soil to completely fill the planter

Answer:

0.02 is in the hundredths place.

Step-by-step explanation:

The decimal point represents the great divide between whole numbers and fractions of whole numbers.

The first digit behind the decimal point is called the “Tenths” place. Since you can get a whole number “one” (which is what the first digit in front of the decimal point is called) you can’t possible have a “one...ths” place.

Right after tenths you have hundredths. (which is what you’re looking for.) This is the second digit behind the decimal point.

After that you have thousandths, ten thousandths, and so on.

Pay close attention to the spelling. “Hundredths” and “hundred” are look similar but could be the difference between an A and an F.

Answer:

A. 13 hours

B. Sparkly clean company

Step-by-step explanation:

Step one:

given

Molly maids company

charges a flat rate of $100 per hour

let the total charges be y

let the number of hours be x

the expression for the total charges for Molly maids is

y=100x---------------1

Step two:

Sparkly clean company

charges $80 per hour

equipment fee=$260

let the total charges be y

let the number of hours be x

the expression for the total charges for Sparkly clean  is

y=80x+260---------------2

A) determine and state the number of hours that must be worked for the cost of both companies to be the same.

Equate equations 1 and 2

100x=80x+260

solve for x, collect like terms

100x-80x=260

20x=260

divide both sides by 20

x=260/20

x=13 hours

B) if it is estimated to take at least 30 hours to company the job, which company will be less expensive

x=30

Molly maids company

y=100x

y=100*30

y=3000

$3000

Sparkly clean company

y=80x+260

y=80*30+260

y=2400+260

$2660

Sparkly clean company  will be less expensive for a 30 hour work
