Answer:

The arc length s = 44 inches

Step-by-step explanation:

We are given:

r = 4 in

Ф = 11 radians

We need to find s

The formula used is: [tex]s=r\theta[/tex]

where s represents arc length, r is radius and Ф is angle in radians

Putting values and finding s

[tex]s=r\theta[/tex]

Put r = 4 and Ф = 11

[tex]s=4\times 11\\s=44[/tex]

So, the arc length s = 44 inches

Answer:

47

Step-by-step explanation:

Answer:

x = 63

Step-by-step explanation:

180 = 47 + 70 + x

180 = 117 + x

180 - 117 = x

63 = x

Answer:

the answer is F

Step-by-step explanation:

The correct option is option F , that is figure F shows the rotational symmetry.

What is rotational symmetry ?

An object's ability to maintain the same shape when rotated about its own axis is known as rotational symmetry.

Some figures are given and we have to tell which figure doesn't illustrate rotational symmetry.

Let's check them all , one by one.

F)

We know that rotational symmetry meant a figure looks the same when it is rotated. Here , if we consider a point on the circle and try to rotate it about its own axis , then we get to know that the figure does not looks same in all directions.

So , this figure doesn't have rotational symmetry.

G)

This figure is when rotated about its own axis , we get that that it looks same in all directions. This figure has rotational symmetry.

H)

This figure also has rotational symmetry.

G)

We know that a triangle follows the rotational symmetry. If we rotate it , we get the same looks in all directions. This figure has the rotational symmetry.

Therefore , the correct option is option F , that is figure F shows the rotational symmetry.

b) 30

c) 40

Step-by-step explanation:

(no entiendo mucho espanol pero voy a ayudar...)

a) hay 10 que haces los dos, 30 que solo estudien, y 40 que solo trabajan. Con eso, 80-10-30-40 = 5, y asi tienes 5 personas que no estudian y no trabajan

b) las personas que estudian son 40, y 10 trabajan tambien, asi solo tienes 30 personas que unicamente se dedican a estudiar.

c) las personas que trabajan son 50, y 10 estudian tambien, asi solo tienes 40 personas que unicamente se dedican a estudiar.

Step-by-step explanation:

Answer:

The value of f is 5

Step-by-step explanation:

Initially, the number of frog tadpoles = f

The initial probability of catching a frog tadpole = f/20

Adding 10 more frog tadpoles,

Number of frog Tadpoles = f +10

Total number of tadpoles in the pond = 20+10 = 30

new probability of catching a frog tadpole = (f+10)/30

New probability of catching a frog tadpole = 2 x Initial probability of catching a frog tadpole

(f+10)/30 = 2 x (f/20)

(f+10)/30 = f/10

f+10 = f x 30/10

f+10 = 3f

2f = 10

f = 5

Answer:

13/20

Step-by-step explanation:

Write 0.65 as [tex]\frac{0.65}{1}[/tex]

Multiply both numerator and denominator by 10 for every number after the decimal point

0.65 × 100/1 × 100 =  [tex]\frac{65}{100}[/tex]

[tex]\frac{65}{100}[/tex] reduced is 13/20

Answer: 1-7/8.

Step-by-step explanation;

Division of fractions is equivalent to multiplication by the reciprocal of the second fraction:  5/8 / 1/3 = 5/8 * 3/1.

Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:  15/8.

15 ÷ 8 = 1R7, therefore:  1-7/8.

The required, 15/8, is the simplest form. It cannot be further reduced since the numerator (15) and the denominator (8) have no common factors other than 1.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator. Let's calculate the division:

(5/8) ÷ (1/3)

Find the reciprocal of the second fraction:

Reciprocal of (1/3) = 3/1 = 3

Now, multiply the first fraction by the reciprocal of the second fraction:

(5/8) * 3 = (5 * 3) / 8 = 15 / 8

So, the answer to 5/8 divided by 1/3 in simplest form is 15/8.

Answer:

3/10

Step-by-step explanation:

Answer: 3/10

Work (Easy Method): So the easy method is to count how many spaces are there, and since there are 10, you choose the 3/10

Work (Harder Method): You count the White spaces in both, and put it over the total spaces, So, since there's 4 white spaces in Tracy, and 10 total spaces, you do 4/10, and same goes with Carol. So, you just subtract 7/10 by 4/10, and you get 3/10

Step-by-step explanation:

if you use the number on the top of the shape on the right, then you have to compare it to the number on the top of the shape on the left. and vice versa for the numbers on the side of the shapes. it doesn't matter what number in the comparison goes on top of the fraction, but option C is the only answer with the correct calculations.

Answer:

B: y = -2/3x - 10/3

Step-by-step explanation:

The point is at (-2,-2), therefore when you input -2 into the desired equation, it should yield -2 as our output. If we use the equation B, the equation becomes

-4/3 - 10/3 which is -6/3. After dividing it we get -2 as the output.

To find the line yourself we use the point slope formula

y - y1 = m(x - x1)

The line is parallel to the one on the graph so the slope or m is equal to -2/3

We input the coordinates we want for y1 and x1.

y - (-2) = -2/3 (x - (-2))

y + 2 = -2/3x - 4/3

y + 6/3 = -2/3x - 4/3

y = -2/3x - 10/3

Note: The difference should read 18 not 28, it must be a typo. In general such difference must be a multiple of 9.  

Let the digits are x and y.

If the first digit is x and the second digit is y, then the number is 10x + y.

According to the question we have:

Add up the equations:

Find y:

The number is 97.

Answer:

y= 15

Step-by-step explanation:

The square shown on the left side of the problem is equivalent to 90 degrees.   Two 90 degree angles (complementary angle) equals to l80 degrees (a straight angle). Equation that is set up to solve for y: 6y= 90. 90 divided by 6 is 15.
