2/3 divided by 4/5 qwertyuioppasdfghjklzxcvbnm

Answers

Answer:

5/6

Step-by-step explanation:

The solution of the given fraction is 5/6.

Given that:

Fraction: divided 2/3 by 4/5

To calculate the division of fractions, simply need to multiply the first fraction by the reciprocal of the second fraction.

[tex]\dfrac{2/3}{4/5} =\dfrac{2}{3} \times \dfrac{5}{4}\\\dfrac{2/3}{4/5} =\dfrac{(2 \times5)}{(3 \times4) }\\\dfrac{2/3}{4/5} =10 / 12[/tex]

To simplify the fraction, you can divide both the numerator and the denominator by their greatest common divisor, which is 2:

10 / 12 = 5 / 6

So, 2/3 divided by 4/5 is equal to 5/6.

Hence, the required result is 5/6.

Find the length of d in the figure below if a = 8 in., b = 3 in., and c = 4 in. Round your answer to the nearest tenth.

Answers

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

First we find the diameter ((h)) of the rectangle on the floor using the Pythagorean theorem.

So we have :

[tex] {h}^{2} = {a}^{2} + {b}^{2} [/tex]

[tex] {h}^{2} = 64 + 9 [/tex]

[tex] {h}^{2} = 73 [/tex]

[tex]h = \sqrt{73} [/tex]

_________________________________

Step (2)

Now we another using of Pythagorean theorem for finding d :

[tex] {d}^{2} = {h}^{2} + {c}^{2} [/tex]

[tex] {d}^{2} = 73 + 16 [/tex]

[tex] {d}^{2} = 89 [/tex]

[tex]d = \sqrt{89} [/tex]

[tex]d = 9.4[/tex]

For her birthday party, Tausha is preparing bags of treats to share with her friends. She has 18 candy bars and 12 packs of gum. Tausha wants to use all of her candy and gum. What is the greatest number of bags of treats that Tausha can make if each of the bags has the same number of candy bars and packs of gum in it? How many candy bars and how many packs of gum will be in each bag?

Answers

Answer:

Tausha can make maximum 6 bags that has the same number of candy bars and packs of gum in it.

Number of candy bars in each bag [tex]=3[/tex]

Number of packs of gum in each bag [tex]=2[/tex]

Step-by-step explanation:

Given:

Number of candy bars = 18

Number of packs of gum = 12

To find: the greatest number of bags of treats that Tausha can make if each of the bags has the same number of candy bars and packs of gum in it

and number of candy bars and packs of gum in each bag

Solution:

Take H.C.F of 18 and 12

[tex]18=2(3^2)\\12=2^2(3)[/tex]

So,

H.C.F of 18 and 12 is 2(3) = 6

Therefore,

Tausha can make maximum 6 bags that has the same number of candy bars and packs of gum in it.

Number of candy bars in each bag = [tex]\frac{18}{6}=3[/tex]

Number of packs of gum in each bag = [tex]\frac{12}{6}=2[/tex]

can someone pls help i have been stuck on this one for a little while ):

Answers

Answer:

This is not correct

Step-by-step explanation:

on the right side is 3.2 (x-5) this means that it represents 3.2 * (x-5). You have to multiply (according to the distributive property) 3.2 by x and 3.2 by (-5), so you get 3.2x + (3.2*-5) = 3.2x -16

The left side says 3.2x-5, that is clearly not equal to 3.2x-16.

It is impossible to say that there are infinitely many solutions as there are actually no possible solutions. Set the functions equal so it is:

3.2x-5 = 3.2x-16

solve for x by subtracting the 3.2x from the right side and the left side, then add 5 to both sides to isolate the variable with the other terms.

You get 0=11

That is not true.

The water depth in a lake decreases at a rate of 2 inches per day because of evaporation. How much does the water depth change in 8 days? In 15 days? In 8 days, the water depth changes by inches. In 15 days, the water depth changes by inches.

Answers

Answer: In 8 days it will decrease by 16 inches and  in 15 days the water depth changes by 30 inches.

Step-by-step explanation:

The water depth decreases at a rate of 2 inches per day so in this case if were to write it as an expression it will be -2x  where x is the number of days.

We will have to set it equal the total amount that it has decreased which will be y.

y= -2x    If x  represent the number of days we will put in the days and solve for y.

y = -2(8)

y = -16     This means that in 8 days it will decrease by 16 inches.

y = -2(15)

y= -30   This also means that in 15 days the water depth changes by 30 inches.

What is the equation of a line that passes through the point (9, −3) and is parallel to the line whose equation is 2x−3y=6?


Enter your answer in the box

Answers

Answer:

y = 2/3x - 9

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step 1: Define

Point (9, - 3)

2x - 3y = -6

Step 2: Rewrite given equation

-3y = -2x - 6

y = 2/3x + 2

So our m = 2/3 (Parallel lines have the same slope but different y-intercepts)

Step 3: Find y-int of parallel line

y = 2/3x + b

-3 = 2/3(9) + b

-3 = 6 + b

b = -9

Step 4: Write parallel line equation

y = 2/3x - 9

Answers

Answer:

x= 17

HJ= 27

JK= 153

HK= 180

Step-by-step explanation:

If HJ=x+10

JK=9x

KH=14x−58

a) The diagram of sketch of the segments described above is attached to this answer.

b) KH = HJ + JK

14x - 58 = (x + 10) + 9x

14x - 58 = x + 10 + 9x

c)

14x - 58 = x + 10 + 9x

14x - 58 = 10x + 10

Collect like terms

14x - 10x = 10 + 58

4x = 68

Divide both sides by 4

4x/4 = 68/4

x = 17

d)

x= 17

HJ= x + 10

= 17 + 10

= 27

Hence, HJ = 27

JK= 9x

= 9 × 17

= 153

Hence, JK = 153

HK=14x −58

HK = 14 × 17 - 58

= 238 - 58

= 180

Hence, HK = 180
