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:

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.

Answer:

2.8

Step-by-step explanation:

This is because you can divide 2 by 3. Then multiply 4.2 by that number and that gets you your answer.

4.2 ÷ 3 = 1.4

1.4 times 2 = 2.8

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.

Both parts are needed to form the full solution set.

In the second step, I added 7 to both sides. In the third step, I divided both sides by 3. Afterward, I used the rule that [tex]|x| \ge k[/tex] breaks down into [tex]x \ge k \ \text{ or } \ x \le -k[/tex] for some positive value k. The last thing to do is to subtract 1 from both sides to fully isolate d.

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
