Answer 1

Answer:

D

Step-by-step explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

   = πr² × [tex]\frac{80}{360}[/tex]

   = π × 0.9² × [tex]\frac{8}{36}[/tex]

   = 0.81π × [tex]\frac{2}{9}[/tex]

   = 0.09π × 2

   = 0.18π in² → D

Rearrange w= 3(2a + b) – 4 to make a the subject.

Answers

Answer:

a = (w - 3b + 4)/6

Step-by-step explanation:

w = 3(2a + b) - 4

w = 6a + 3b - 4

6a + 3b - 4 = w

6a = w - 3b + 4

a = (w - 3b + 4)/6

Two trains are 1.5 miles apart, train a is traveling at 3/4 the speed of train b if they meet in 4 minutes how fast is each train going

Answers

Answer:

Train A is travelling at a speed of 12.857 miles per hour and train B at a speed of 9.643 miles per hour.

Step-by-step explanation:

Let suppose that train A begins in position [tex]x = 0\,mi[/tex] and the train B in position [tex]x = 1.5\,mi[/tex], if [tex]v_{B} = \frac{3}{4}\cdot v_{A}[/tex] and both trains move at constant speed, then we have  the following kinematic equations:

Train A

[tex]x_{A} = x_{A,o}+v_{A}\cdot t[/tex] (1)

Train B

[tex]x_{B} = x_{B,o}-v_{B}\cdot t[/tex] (2)

If both trains meet each other, then [tex]x_{A} = x_{B}[/tex]. If we know that [tex]x_{A,o} = 0\,mi[/tex], [tex]x_{B,o} = 1.5\,mi[/tex], [tex]v_{B} = \frac{3}{4}\cdot v_{A}[/tex] and [tex]t = \frac{1}{15}\,h[/tex], then we have the following expression:

[tex]x_{A,o}+v_{A}\cdot t = x_{B,o}-v_{B}\cdot t[/tex]

[tex]x_{A,o} + v_{A}\cdot t = x_{B,o} - \frac{3}{4}\cdot v_{A}\cdot t[/tex]

[tex]\frac{7}{4}\cdot v_{A}\cdot t = x_{B,o}-x_{A,o}[/tex]

[tex]v_{A} = \frac{4\cdot (x_{B,o}-x_{A,o})}{7\cdot t}[/tex]

[tex]v_{A} = 12.857\,\frac{mi}{h}[/tex]

Then, the speed of the train B is:

[tex]v_{B} = 9.643\,\frac{mi}{h}[/tex]

Train A is travelling at a speed of 12.857 miles per hour and train B at a speed of 9.643 miles per hour.

Ronald has 5 2/3 cups of a smoothie he then drank 1 3/4 cups of the smoothie how many cups were left

Answers

Answer:

4 1/6 cups of the smoothie were left.

Step-by-step explanation:

The LCD here is (3)(4) = 12.

Thus, 5 2/3 cups equals 5 8/12 and 1 3/4 cups equals 1 6/12 cups.

Subtract 1 6/12 cups from the original 5 8/12 cups.  We get:

5 8/12

-1  6/12

-----------

 4 2/12, or 4 1/6.

4 1/6 cups of the smoothie were left.

Answers

Answer:

See solutions below

Step-by-step explanation:

Complete question

A circle's circumference is approximately 44 cm.

Complete each statement using one of these values: 7, 11, 14, 22, 88, 138, 154, 196, 380, 616.

The circle's diameter is approximately cm.

The circle's radius is approximately cm.

The circle's area is approximately cm2.

Circumference of the circle =2πr

r is the radius of the circle

Circumference of the circle = 2(3.14)r

44 = 2(3.14)r

22 = 3.14r

r = 22/3.14

r = 7.0cm

The circle's radius is approximately 7cm.

Since diameter = 2r

diameter = 2 * 76

diameter = 14cm

The circle's diameter is approximately 14cm.

Area of the circle = πr²

Area of the circle = 3.14(7)²

Area of the circle = 3.14(49)

Area of the circle = 153.86sq.cm

The circle's area is approximately 154cm^2.

Answers

Answer:

red = 28 apples

green = 13 apples

equations:

r + g = 41

r = g + 15

Step-by-step explanation:

r = number of red

g = number of green

r = g + 15 (the number of red apples is 15 more than the number of green apples)

r + g = 41

Substitute the firs equation into the second and solve for a numerical value of g

(g + 15) + g = 41

2g + 15 = 41

2g = 26

g = 13

Now solve for a numerical value of r

r = g + 15

r = 13 + 15

r = 28

checking the math:

r + g = 41

28 + 13 = 41

y = -x-4
C.
y=x+4

d. y = x-4

Answers

Answer:

y = -x + 4

Step-by-step explanation:

Mathematically, the equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

from the plot, the y intercept is 4

So we have;

y = mx + 4

To get the value of m, we substitute the coordinates of any point and solve for m

we select the point; (4,0)

so;

0 = m(4) + 4

4m = 0-4

4m = -4

m = -1

so the equation of the line is;

y = -x + 4

What happens to the value of the expression \dfrac{10}{d} d 10 ​ start fraction, 10, divided by, d, end fraction as ddd increases from a small positive number to a large positive number?

Answers

Answer:

The quotient decreases

Step-by-step explanation:

Give the expression :

10 / d

What happens to the expression as d increases. from small positive to large positive ;

d in the expression is the denominator ;the value obtained by dividing the numerator by the denominator is the quotient.

Since the value of the numerator is constant ;

As the value of d increases, the quotient obtained becomes smaller `

For instance,

Let

d = 2;

10 /2 = 5

d = 3

10 / 3 = 3.333

d = 4

10 / 4 = 2.5

And the trend continues

An experiment consists of rolling a number cube (dice). What is the probability of rolling a number GREATER THAN 4? Express your answer as a fraction in the simplest form.

Answers

Answer:

1/3

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur

Probability = Expected/Total outcome

Since the experiment requires rolling a dice

S = {1, 2, 3, 4, 5, 6}

Total outcome n(S) = 6

Number greater than 4 are;

Events E = {5,6}

Expected outcome n(E) = 2

Probability of rolling a number greater then 4 = 2/6

Probability of rolling a number greater then 4 = 1/3

Givens

x1 = -5

x2 = -3

y1 = 6

y2 = - 1

Solution

d = sqrt( ( -3 - -5)^2 + (-1 - 6)^2 )

d = sqrt( ( -3 + 5)^2 + (-7)^2 )

d = sqrt( 2^2 + 49)

d = sqrt(4 + 49)

d = sqrt(53)
