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
A pond contains 20 tadpoles, of which f are frog tadpoles and the others are toad tadpoles. If 10 more frog tadpoles are added to the pond, the probability of catching a frog tadpole is doubled. Find f
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
In the diagram, △RST∼△R′S′T′ . Determine the length of RS¯¯¯¯¯¯¯ . Show your work on paper or in the box below.
The length of RS is such that △RST∼△R′S′T′ will be 6 feet.
What is the similarity?Similar figures are those figures which are identical in shape, but not necessarily in size.
Two squares with sides of 10 and 5 are similar because their shape is exact but the size is different.
Given two triangles are similar △RST∼△R′S′T′
If two triangles are similar then the ratio of the corresponding side must be the same.
Therefore,
RS/R'S' = TS/T'S'
(12x + 2)/(5x + 1) = 9/4
By cross multiplication,
48x + 8 = 45x + 9
3x = 1
x = 1/3
Therefore,RS = 12(1/3) + 2
⇒ 6 feet
Hence "The length of RS is such that △RST∼△R′S′T′ will be 6 feet".

A. y=-2/3x-4/3
B. y= - 2/3x-10/3
C. y= -2/3x-2/3
D. y= -2/3x -17/4
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

Which figure below does not illustrate rotational symmetry?
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.

5/8 divided by 1/3 in simplest form
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.

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.

A number consists of two digits. The sum of its digits is 16. If 28 is subtracted from the number, the digits interchange their place. Find the number. |.Give the answer only
Answer:
The number is 97Step-by-step explanation:
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:
x + y = 1610x + y - 18 = 10y + x ⇒ 9x - 9y = 18 ⇒ x - y = 2Add up the equations:
x + y + x - y = 16 + 22x = 18x = 9Find y:
9 + y = 16y = 7The number is 97.
