Evaluate -7 1/3 - (-2/5)=​

Answer:

4.085 x 10^3

Step-by-step explanation:

just use powers to figure out these questions. it always starts from a single digit! for example if the number is 4,000 it would just be 4 x 10^3 but because theres more unique numbers then it would be a decimal

Answer: 3.481 x 10^8

:)

Step-by-step explanation:

(5.9 x 10^3)(5.9 x 10^4)

(5.9 x 5.9) (10^3 x 10^4)

34.81 x 10^7

= 3.481 x 10^8

Answer:

There are 56 ways to choose 5 from 8 varieties.

Step-by-step explanation:

a) Choosing 5 out of 8

This is a combination problem, given by the formula below:

C(n,r)=?

C(n,r)=C(8,5)

=8!/(5!(8−5)!)

= 56

b) A combination is the number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed. The result of this combination of 5 out of 8 varieties shows that there 56 ways one can choose.  The formula is given by 8 factorial divided by (5 factorial by 3 factorial).

Answer:

12 strawberries

Step-by-step explanation:

Let

[tex]S = Strawberry[/tex]

[tex]G = Grape[/tex]

[tex]H = honeydew[/tex]

Given

[tex]S : G = 3 : 9[/tex]

S : H = 6 : 14

Required

Solve for S when G = 36

To do this, we make use of the first ratio

[tex]S : G = 3 : 9[/tex]

Substitute 36 for G

[tex]S : 36 = 3 : 9[/tex]

Convert ratio to fractions

[tex]\frac{S}{36} = \frac{3}{9}[/tex]

[tex]\frac{S}{36} = \frac{1}{3}[/tex]

Cross Multiply

[tex]S * 3 = 36 * 1[/tex]

[tex]3S = 36[/tex]

Divide through by 3

[tex]\frac{3S}{3} = \frac{36}{3}[/tex]

[tex]S = \frac{36}{3}[/tex]

[tex]S = 12[/tex]

The (b) part of the question can not be solved with the given details.

However, some equivalent fractions are:

[tex]\frac{1}{2} = \frac{2}{4}[/tex] ---- 0.5

[tex]\frac{5}{15} = \frac{10}{30}[/tex] --- 0.33

[tex]\frac{4}{7} = \frac{8}{14}[/tex] --- 0.57

To get the equivalent fractions, you have to convert the fractions to decimal and then make comparison.

Answer:

15 units

Step-by-step explanation:

UW is the midsegment of ΔVXY,

By midsegment theorem of a triangle,

"Segment joining the midpoints of two sides of a triangle is parallel to the third side and measure of midsegment is half of the length of the third side."

UW = [tex]\frac{1}{2}(XY)[/tex]

Since, XY = 30 units

UW = [tex]\frac{1}{2}(30)[/tex]

      = 15 units

Therefore, length of the midsegment UW = 15 units will be the answer.

Hey there!

“x – 3 < 2”

Let’s change your current question into a(n) equation to make it EASIER to solve (this is for temporary purposes ONLY)

• Temporary question

x – 3 = 2

• First: ADD BOTH SIDES by 3

x – 3 + 3 = 2 + 3

• CANCEL: –3 + 3 because that gives you 0

• KEEP: 2 + 3 because that helps solve for x

• New temporary question: 2 + 3 = x

2 + 3 = 5

The temporary question answer is: x = 5 ✅

NOW LETS SOLVE FOR YOUR ACTUAL EQUATION (just saying it REQUIRES the SAME steps as the temporary question just a TAD bit differently!)

x – 3 < 2

• FIRST: ADD both SIDES BY 3

x – 3 + 3 < 2 + 3

• CANCEL: –3 + 3 because that gives you 0

• KEEP: 2 + 3 because that helps us compare the answer with x

• New equation: x < 2 + 3

2 + 3 = 5

x < 5

Answer to your given question is: x < 5 ☑️

Good luck on your assignment and enjoy your day!

Answer:

21% is the answer :)

The sum of all multiples of 6 between 12 and 87 is equal to 624.

The multiples of 6 are of the form: 6*n

Where n is an integer.

The multiples between 10 and 87 are:

6*2 = 12

6*3 = 13

...

6*14 = 84

Then the sum of all these multiples can be written as:

[tex]6*2 + 6*3 + 6*4 + ... + 6*14\\\\= 6*(2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14) = 624[/tex]

The sum of all multiples of 6 between 12 and 87 is equal to 624.

A sand dune stands 5 feet above sea level. The hill is eroding at a rate of 1 foot per 20 years. Let y represent the height of the sand dune after x years. Which equation represents the situation?

y = negative StartFraction 1 Over 20 EndFraction x minus 5

y = negative StartFraction 1 Over 20 EndFraction x + 5

y = negative 20 x minus 5

y = negative 20 x + 5

Step-by-step explanation:

(5x +2) + (4x -5)

Remove the parenthesis:

5x + 2 + 4x -5

Now combine the like terms:

5x + 4x = 9x

2 - 5 = -3

Answer:

0.98732

Step-by-step explanation:

Given that :

Mean = 10 minutes

Variance = 2 minutes

For less than equal 40 jobs

Mean (m) = 40 * 10 = 400 minutes

Variance = 2 * 40 = 80 minutes

Standard deviation (s) = √variance = √80

Converting hours to minutes

X = 60 * 7 = 420 minutes

P(X≤ 420) :

Z = (x - m) / s

P(X≤ 420) :

Z = (420 - 400) / √80

Z = 20 / √80 = 20 / 8.9442 = 2.236

P(Z ≤ 2.236) = 0.98732

The probability that the machine processes less than or equal should be 0.98732

Since

Mean = 10 minutes

Variance = 2 minutes

For less than equal 40 jobs

Mean (m) = 40 ( 10) = 400 minutes

Variance = 2 (40) = 80 minutes

Now

Standard deviation (s) = √variance = √80

Now here we Converting hours to minutes

So,

X = 60 (7) = 420 minutes

Now

P(X≤ 420) :

Z = (x - m) / s

Z = (420 - 400) / √80

Z = 20 / √80

= 20 / 8.9442

= 2.236

Now finally

P(Z ≤ 2.236)

= 0.98732

Hence, The probability that the machine processes less than or equal should be 0.98732
