Answer:

-4/11

Step-by-step explanation:

Answer:

a = 18 units

b = 9√3 units

Step-by-step explanation:

By applying sine rule in the given triangle,

sin(30°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{1}{2}=\frac{9}{a}[/tex]

a = 18 units

Now apply cosine rule in the given triangle,

cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{\sqrt{3}}{2}=\frac{b}{a}[/tex]

[tex]\frac{\sqrt{3}}{2}=\frac{b}{18}[/tex]

b = [tex]\frac{18\sqrt{3} }{2}[/tex]

b = [tex]9\sqrt{3}[/tex] units

Answer:

number of dimes = 15

number of quarters = 2

Step-by-step explanation:

total money = $2 = 200 cents

types of coins are dimes and quarters

number of dimes are 13 more than quarters

let number of dimes be x and quarters be y

so our equation =

10x + 25y = 200

x = (y+13)

10(y+13) +25y= 200

10y + 130 +25y = 200

35y + 130 = 200

y = 70/35 = 2

cross checking :

x = y+13 = 15

amount = 10x15 + 25x2 = 150 + 50 = 200 cents = $2.

determine 3 ways to have 13 more dimes than quarters:

we can use linear equations and tables to solve.

Answer:

(0, 19)

Step-by-step explanation:

Find the equation.

Find the slope:

[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

22-16/1-(-1) = 6/2 = 3

Here's our equation so far:

y = 3x + b

Find b by plugging in one pair of (x,y) coordinates.

22 = 3(1) + b

22 = 3 + b

b = 19

Now we now the equation:

y = 3x + 19

So, the y-intercept is 19.

Answer:

Step-by-step explanation:

The white area is the area of the circle minus the area of the triangle.

Aw=pr^2-hb/2

Aw=p4^2-6.5(6)/2

Aw=16p-19.5

The probability of selecting the white area is the white area divided by the area of the circle

P(W)=(16p-19.5)/(16p), p=3.14

P(W)=0.61

Answer:

74%

Step-by-step explanation:

Given data

Number of books= 8000

Number of non-fiction books= 5920

Percentage of non-fiction books

=5920/8000*100

=0.74*100

= 74%

Hence, the percentage of Non-fiction books is 74%

Step-by-step explanation:

2a-10=5(4+.2a)

Use the distributive property to multiply 5 by 4+0.2a..

2a-10=20+a

Subtract a from both sides.

2a-10-a=20

Combine 2a and -a to get a.

a-10=20

Add 10 to both sides.

a=20+10

Add 20 and 10 to get 30.

a=30

Answer: Pipes

Step-by-step explanation: Pipes transfer water around and veins transfer blood around the body

Answer:

D. pipes

Step-by-step explanation:

Water isn't to lungs

water comes from a sink but it doesn't have the same relationship to the sink as blood does to veins

Water isn't to the ocean like blood:veins because the water is uncontrolled and is everywhere

that leaves water being to pipes like blood is to vessels and the image describes it better than I do

Answer:

2.396 :)

Step-by-step explanation:

The units of measurement go like this:

Kilo, hecto, deca, unit, deci, centi, mili

When you move to the right, you move the decimal one place to the right, and when you move left, you move the decimal one place to the right

If you’re changing milliliters to liters (unit), you have to more the decimal 3 times to the left. This makes it 2.396 liters

Answer:

X= -6, Y= 3

Step-by-step explanation:

1)

- X - Y = 3

- X - 3= Y

Y= - X - 3

2)

6X + 2Y = -30

3X + Y = -15

Y = -15 - 3X

3) Combine

- X- 3 = - 15 - 3X

- X = -15 - 3X +3

-X + 3X = - 12

2X = - 12

X= - 6

4)

- X-Y=3

-(-6) - Y = 3

-Y= 3-6

-Y= - 3

Y = 3

Answer: X= -6, Y= 3

Answer:

Mass of a bouquet  = v + 3d + 4t

Step-by-step explanation:

Mass of daffodil = d gm

Mass of Tulip = t gm

Mass of vase = v gm

Mass of a bouquet = mass of vase + Mass of 3 daffodils + Mass of 4 tulips

=> Mass of a bouquet  = v + 3d + 4t

Flower bouquet weight = v + 3d + 4t

Answer:

Step-by-step explanation:

Situation Expression

Number of bouquets 555

Mass of one bouquet 3d+4t+v

Mass of the tulips in one bouquet   4t

Answer:

m<BHY = 90

m<RKH = 36

m<HBK = 54

Step-by-step explanation:

The diagonals in a kite are perpendicular, meaning that m<BHY has to be a right angle, and since KY bisects <RKB, <BKH≅<RKH which is 37. Because the angles in a triangle add up to 180, you can use subtraction to find out what the other missing angle, <HBK, is.

The required area covered by 10 tiles having dimensions 3/2 feet by 3/2 feet.

The square is a 4 sided figure, each side of the square is equal and make a right angle.

The area of square having sided a unit can be given by a² square unit.

Given that,

The length of tile = 3/2 feet,

And the width of tile = 3/2 feet.

Total number of tiles = 10.

The tiles are in square shape.

The area of one tile = 3/2 x 3 / 2 = 9 / 4 square feet

The area of 10 tiles = 9/4 x 10 = 22.5 square feet.

The area covered by 10 tiles is  22.5 square feet.
