just cut 2 in half then 2/9 in half

Answer:

2 1/9

Step-by-step explanation:

turn the mixed number into an irregular fraction then divide.

38/9 ÷ 2

38/9 * 1/2 = 38/18 because you multiply by the reciprocal

2 1/9 is the answer

Answer:

Check bolded below

Step-by-step explanation:

1)radius = 10 in (given), diameter = 2*radius = 2(10 in) = 20 in

formula for circumference => 2πr => 2π(10)

circumference = 20π in

2)diameter = 12 ft (given), radius = 1/2*diameter = 1/2(12 ft) = 6 ft

formula for circumference => 2πr => 2π(6)

circumference = 12π ft

3)radius = 3 m (given), diameter = 2*radius = 2(3 m) = 6 m

formula for circumference => 2πr => 2π(3)

circumference = 6π m

4)diameter = 18 cm (given), radius = 1/2*diameter = 1/2(18 cm) = 9 cm

formula for circumference => 2πr => 2π(9)

circumference = 18π cm

1.

radius = 10 in

diameter = 10 × 2 = 20 in

formula = π × d

circumference = π × 20 = 62.83 in

2.

radius = 12 ÷ 2 = 6 ft

diameter = 12 ft

formula = π × d

circumference = π × 12 = 37.70 ft

3.

radius = 3 m

diameter = 3 × 2 = 6 m

formula = π × d

circumference = π × 6 = 18.85 m

4.

radius = 18 ÷ 2 = 9 cm

diameter = 18 cm

formula = π × d

circumference = π × 18 = 56.55 cm

There were 50 questions on her exam.

To find this answer, first make the percentage a decimal by dividing 72 by 100. This will give you 0.72, which you divide into 36 (36 ÷ 0.72). Doing so reverses the percentage, and gives you the total amount of questions. Thus meaning your answer is 50.

Answer:

10.63cm

Step-by-step explanation:

The formula for calculating the distance between two coordinate is expressed as;

D = √(x2-x1)²+(y2-y1)²

Given the coordinates (3, -1) and (-5, 6)

D = √(-5-3)²+(6-(-1))²

D = √(-5-3)²+(6+1)²

D = √(-8)²+(7)²

D = √64+49

D = √113

D = 10.63cm

Hence the shortest distance between P and Q is 10.63cm

Answer:

One possible solution be -

Mrs. Cho is brings type A cans = 10

Mrs. Cho is brings type B cans =  3

Step-by-step explanation:

Let us assume

Mrs. Cho is brings type A cans = x

Mrs. Cho is brings type B cans = y

As given,

For a type A can, she gets 5 cents and For type B can, she gets 10 cents

As we have x Type A cans and y Type B cans

And she has redeemed  no more than 95 cents

⇒5x + 10y ≤ 95           .......(1)

Also given,

She has redeemed at least 11 cans

⇒ x + y ≥ 11           ........(2)

∴ we get

x + y ≥ 11  

5x + 10y ≤ 95

By applying graphical method , we get

The equations become

5x + 10y = 95       .......(1)

x + y = 11              ........(2)

Table for equation (1) -

x                   y

0                    9.5

19                    0

Table for equation (2) -

x               y

0              11

11              0

The two lines intersect at point (3, 8)

So the possible combinations are in the shaded portion which is covered by both the lines.

One possible combination is ( 10, 3) which lies in the shaded region.

So,

Mrs. Cho is brings type A cans = x = 10

Mrs. Cho is brings type B cans = y = 3

Answer:

Y intercept : ( 0 , 25 )

Step-by-step explanation:

Answer:

Step-by-step explanation:

We need to convert function to slope-intrcept form y=mx+b, where:

-0.4x + 0.05y - 1.25 = 0         {multiply both sides by 20}

-8x + y - 25 = 0                    {add (8x+25) to both sides}

y = 8x + 25     ⇒   b = 25

Therefore y-intercept of the line is (0, 25)

The amount of money in the account after adding simple interest of 7% rate  is respectively $17.5, $52.5,  $122.5,  $350

Simple interest is a amount which is calculated for a certain period of time and for a certain rate, in simple interest calculation there are three factors which we consider principle amount(P), rate(R) and time(T).

Every time we calculate simple interest the principle values will be same unlike compound interest.

Formula;    Simple Interest(I) =  P × R × T/100

Given that,

P = $250

R =  7%

For T =  1 year

I  =   250 × 7 × 1/100

  =   $17.5

For T =  3 year

I  =   250 × 7 × 3/100

  =   $52.5

For T =  7 year

I  =   250 × 7 × 7/100

  =   $122.5

For T =  20 year

I  =   250 × 7 × 20/100

  =   $350

Answer:

x=16

Step-by-step explanation:

27/45=(2x+7)/(4x+1)

cross multiply

27(4x+1)=45(2x+7)

108x+27=90x+315

108x-90x=315-27

18x=288

x=288/18

x=16

Looking at the image, The triangle shown below are similar. The value for  x is 16.

Note that in the triangle given, the shapes are similar. Therefore:

27/45 = 2x + 7/  4x + 1

3/5 = 2x + 7/  4x + 1

So:

3 (4x + 1) = 5 (2x + 7)

12x + 3 = 10x + 35

12x - 10x = 35-3

2x = 32

x = 32/ 2

x = 16

Therefore, the value of x is 16.
