1/3 ÷ 2 = ?
please help me!

Answers

Answer 1
Answer: 1/3 divided by two is 0.16666666666
Answer 2
Answer: (1)/(3) ÷ 2
Multiply by the reciprocal:
(1)/(3) × (1)/(2)
This leads us to an answer:
(1)/(6) which is also = to 0.166666........

What is the difference 14/15 - 5/12 written as a decimal?

Answers

14/15 - 5/12 

Common denominator is 60.

(4 * 14)/(4 * 15) - (5 * 5)/(5 * 12)

56/60 - 25/60

= 31/60 as fraction.
= 0.516 as decimal.
14/15 - 5/12
= (168-73)/ (15*12)
= 93/180
= 31/60
= 0.5166666667

If 4x-3/7 which of the following is the inverse of f(x)

Answers

The inverse of the function f(x) is x/4 + 3/28

How to determine the inverse function?

The function is given as:

f(x) = 4x - 3/7

Set f(x) = y

y = 4x - 3/7

Swap the positions of x and y

x = 4y - 3/7

Make y the subject

4y = x + 3/7

Divide by 4

y = x/4 + 3/28

Hence, the inverse of the function f(x) is x/4 + 3/28

Given the line 5x – 2y = 10, Find the equation of a parallel line that passes through the point (2, 3). Find the x- and y-intercepts of both lines. Plot the intercepts and use them to graph both lines on the same set of axes.

Answers

1) subtract 5x from both sides
2) you will be left with 2y= -5x +10
3) then you divide 2 from the three numbers
4) you will be left with y=-5/2x +5
your slope is -5/2x
and your y-intercept is 5
which means your point starts at (0,5) on the graph

1. For triangle ABC, the value of 'x' and 'y' are 15 and 20 respectively.

2. For triangle XYZ, the value of 'x' and 'y' are 17 and 8 respectively.

What is a triangle?

A triangle is a two-dimensionalgeometrical figure that has three sides, three interior angles, and three vertices.

1. ΔABC and ΔXYZ are similar.

Therefore, (AB)/(XY) = (25)/(10)

⇒ (AB)/(XY) = 2.5

Here, AC = x, XZ = 6

Therefore, (AC)/(XZ) = 2.5

⇒ AC = 2.5(XZ)

⇒ x = (2.5)(6)

⇒ x = 15

Again, CB = y, ZY = 8

(CB)/(ZY)= 2.5

⇒ (y)/(8) = 2.5

⇒ y = (2.5) (8)

⇒ y = 20

2. For ΔABC

BC

= \sqrt{AB^(2) - AC^(2)}\n= \sqrt{34^(2) - 16^(2)}\n= √(900)\n= 30(Side can't be negative.)

Here, ΔABC and ΔXYZ are similar.

Therefore,

(BC)/(ZY)\n= (30)/(15)\n= 2

Now, AB = 34, XY = x

Therefore, (AB)/(XY) = 2

⇒ (34)/(x) = 2

⇒ x = (34)/(2)

⇒ x = 17

Again, AC = 16, XZ = y

Therefore, (AC)/(XZ) = (16)/(y) = 2

⇒ (16)/(y) = 2

⇒ y = (16)/(2)

⇒ y = 8

#SPJ3
AB is proportional to XY since they are similar triangles making it 25:10 or 5:2
so then AC:XZ  would be 5x:2x and 5x:6 so then its 15:6 since x is 3 basically set up proportions and so value of the big triangle to the small triangle would be at rails os 5:2
