Which ratio is equivalent to 1:1

Answer:

area of circle having radius 3

is πr²=π*3²=9π square units

area of circle having radius 2

=πr²=π×2²=4π square units

again

area of big circle having radius [3+2]=5 units

=πr²=π×5²=25π square units

Now

area of shaded region=25π-4π-9π=12π or 37.7square units.

Answer:

37.7 sq units

Step-by-step explanation:

Find area if entire region then subtract out each smaller circle

Diameter of entire circle would be 3(2)+2(2) which is 10 so radius is 5

Area of entire region = 25π

Area of circle one = 9π

Area of circle two = 4π

Area of shaded region = 25π - 13π which is 12π or 37.7

Answer:

180/147

Step-by-step explanation:

We need to find the additive inverse of the given numbers.

SOLUTION 1 :-

→ 3/-7 - 11/21

→ -3/7 -11/21

→ 3×-3 - 11 /21

→ -9-11/21

→ -20/21

SOLUTION 2 :-

→ 9/5 ÷ 7/5

→ 9/5 × 5/7

→ 9/7

→ Product of nos . = -20/21 × -9/7

→ Ans = 180/147

Answer:

Step-by-step explanation:

1. Equation

3x + 4 = 25

2. Subtract 4 from both sides

3x + 4 = 25

     - 4    - 4

3. Solve

3x = 21

4. Divide both sides by 3

3x = 21

/3     /3

5. Solve

x = 7

Answer:

B

Step-by-step explanation:

There are many ways to solve this, but the easiest is by noting the first and last points on the plot. These represent the minimum and maximum of the data set, respectively. This means the lowest point is 2, and the highest is 13. So, to find the correct set, just find the corresponding points. In this case, the only set that fits is the second one.

Answer:

Okay done

Step-by-step explanation:

Answer:

let the decided no. be x

Now

[tex] \frac{5}{6} \times \frac{1}{x} = \frac{3}{5} [/tex]

[tex]5 \times 5 = 3 \times 6x[/tex]

[tex]x = \frac{25}{18} or1 \frac{7}{18} [/tex]

is a required answer.

when

no. divided by 5/6 equals 5/3

now

[tex] \frac{5}{6} \times \frac{1}{x} = \frac{5}{3} [/tex]

[tex]5 \times 3 = 5 \times 6x[/tex]

[tex]x = \frac{15}{30} [/tex]

[tex]x = \frac{1}{2} [/tex]is a required answer.

Answer:

113.04 km^2

Step-by-step explanation:

Here the circle radius is 6 km.  The Area formula is A = (3.14)(6 km)^2, or

A = 3.14(36) km^2 = 113.04 km^2    (Answer b)

Answer:

Solution given:

radius [r]=6km

area of circle=πr²=π*6²=36*3.14=113.04cm²

So

b) 113.04 square kilometers is a required answer.

Answer:

80

Step-by-step explanation:

Answer:

Width = 1 m and length = 6 m

Step-by-step explanation:

Let b is the width of the rectangle.

Length = 5+b

The area of the rectangle, A = 6 m²

We need to find the dimensions of the rectangle. We know that, the area of a rectangle is given by :

A = lb

[tex]6=(5+b)b\\\\6=5b+b^2\\\\b=-6, b=1[/tex]

Width of the rectangle = 1 m

Length of the rectangle = 5+b = 6 m

Hence, this is the required solution.

Answer:

The statement is false.

Step-by-step explanation:

A parallelogram is a figure of four sides, such that opposite sides are parallel

A rectangle is a four-sided figure such that all internal angles are 90°

Here, the statement is:

"A rectangle is sometimes a parallelogram but a parallelogram is always a

rectangle."

Here if we found a parallelogram that is not a rectangle, then that is enough to prove that the statement is false.

The counterexample is a rhombus, which is a parallelogram that has two internal angles smaller than 90° and two internal angles larger than 90°, then this parallelogram is not a rectangle, then the statement is false.

The correct statement would be:

"A parallelogram is sometimes a rectangle, but a rectangle is always a parallelogram"

Answer:

3

Step-by-step explanation:

Answer:

See below.

Step-by-step explanation:

A) The rate of change would be dividing the number of songs wanted (150) by the number of weeks downloading (5).

150/5 = 30

As the total quantity wanted is becoming less every week the rate of change would be negative so it becomes -30.

The initial value is 150, which is the total number of songs she wants.

B)

We’ll use A(0, 150), and B(1, 120)

calculate the slope:

m = (y2- y1)/(x2 - x1) = (120 - 150)/(1 - 0)

(in other words: delta y / delta x)

m = -30

Finally, use the line equation in form point-slope:

y - y1 = m(x - x1)

y - 150 = -30(x - 0)

y = -30x + 150

Answer:

1 / 3

Step-by-step explanation:

Bag 1 :

Yellow = 3

Green = 2

Red = 1

Total = 3 + 2 +1 = 6

Bag 2 :

Yellow = 3

Green = 3

Red = 3

Total = 3 + 3 + 3 = 9

P(not yellow from bag 1) = (green + red) / total = 3 /6 = 1/2

P(not yellow from bag 2) = (green + red) / total = 6/9 = 2 /3

P(neither is yellow) = 1/2 * 2/3 = 2 / 6 = 1/3

Step-by-step explanation:

Answer:

31). Maximum height = 100 feet

32). Time to hit the ground = 5 seconds

Step-by-step explanation:

31). Equation modeling the height 'h' of the ball is,

     h = -16t² + 80t

     For the maximum height of the ball,

     Find the derivative of 'h' with respect to time 't' and equate it to zero.

     [tex]\frac{dh}{dt}=\frac{d}{dt}(-16t^2+80t)[/tex]

          [tex]=-32t+80[/tex]

     [tex]\frac{dh}{dt}=0[/tex]

     [tex]-32t+80=0[/tex]

     [tex]t=\frac{80}{32}[/tex]

     [tex]t=2.5[/tex] seconds

     That means after 2.5 seconds ball will reach the maximum height.

     By substituting [tex]t=2.5[/tex] in the equation,

     [tex]h=-16(2.5)^2+80(2.5)[/tex]

     [tex]h=100[/tex] feet

     Therefore, maximum height achieved by the ball is 100 feet.

32). If the ball follows the parabolic path,

      Time taken by the ball to reach the maximum height = Time taken by  the ball to come back to the ground from the maximum height.

      Time taken by the ball to hit the ground = 2(2.5) = 5 seconds

Answer:

9:30am

Step-by-step explanation:

To find what time simply add all of the minutes together and subtract. All of the steps take 100 minutes to do. 11.10 am is 670 minutes. So 670 - 100 = 570 then divide by 60 to get the time ie 9:30 am

Answer:

using pythagoras theorem

H^2=P^2+B^2

here h=MN ,opposite(P) be 15 and adjacent(B) be 16

(MN)^2=225+256

MN=[tex]\sqrt{481}[/tex]

MN=21.93

after rounding off MN=21.9
