Vanya, a newborn going through a growth spurt, grew out of an average of 250 socks per month from January to March, inclusive. He grew out of an average of 300 socks per month in April and May. Find the average amount of socks Vanya grew out of during the 5 months.

Answer:

$250

Step-by-step explanation:

Total parts:

2+3+9 = 14

500/14 = 250/7

2×250/7 : 3×250/7 : 9×250/7

500/7 : 750/7 : 2250/7

The largest share is 2250/7, the smallest share is 500/7.

Find the difference.

2250/7 - 500/7 = 250

Answer:

$250

Step-by-step explanation:

2x+3x+9x= $500

9x-2x= 7x=?

14x= $500

7x= $500/2= $250

Answer:

The zeroes of a polynomial is the value of x when the polynomial is set to 0.

We can write x² - 2x - 8 = 0. This factors to (x - 4)(x + 2) = 0 and using Zero Product Property the solutions are x = 4, x = -2.

Show that the angles A and B are congruent

Answer:

[tex]\angle A =\angle B =90^\circ[/tex]

Step-by-step explanation:

The diagram of the sled kite is attached below.

The central part of the kite is square.

We know by the property of a square that all its angles are congruent and equal to 90 degrees.

Therefore:

[tex]\angle A =\angle B =90^\circ[/tex]

Angles A and B are congruent.

Answer:

5ab + 8 - 1a^2.

Step-by-step explanation:

Combining like terms, we get 3a^2 - 4a^2 = -1a^2. We get 9ab - 4ab = 5ab. Then we get, 5 + 3 = 8. Together this is 5ab + 8 - 1a^2

Answer:

-[tex] {a}^{2} + 5ab + 8[/tex]

solution,

[tex]3 {a}^{2} + 9ab + 5 - 4 {a}^{2} - 4ab + 3[/tex]

collect like terms:

[tex]3 {a}^{2} - 4 {a}^{2} + 9ab - 4ab + 5 +3[/tex]

Simplify:

[tex] - {a}^{2} + 5ab + 8[/tex]

[tex] = \dfrac{\frac{\sin A}{\cos A} - \frac{\cos A}{\sin A}}{\frac{\sin A}{\cos A} + \frac{\cos A}{\sin A}} [/tex]

[tex] = \dfrac{\sin A \cos A \times (\frac{\sin A}{\cos A} - \frac{\cos A}{\sin A})}{\sin A \cos A \times (\frac{\sin A}{\cos A} + \frac{\cos A}{\sin A})} [/tex]

[tex] = \dfrac{\sin^2 A - \cos^2 A}{\sin^2 A + \cos^2 A} [/tex]

[tex] = \dfrac{\sin^2 A - \cos^2 A}{1} [/tex]

[tex] = \sin^2 A - \cos^2 A [/tex]

Since

[tex] \sin^2 A + \cos^2 A = 1 [/tex]

we know

[tex] \cos^2 A = 1 - \sin^2 A [/tex]

we now substitute to get

[tex] = \sin^2 A - (1 - \sin^2 A) [/tex]

[tex] = \sin^2 A - 1 + \sin^2 A) [/tex]

[tex] = 2\sin^2 A - 1 [/tex]

If the length of a diagonal of a square is a . The length of its side will be a/√2.

The area of the square is found as the square of the length of its side. If the length of a side is a;

Area of a square = side²

Given;

The length of the diagonal is a and the side of the square is x then;

From the pythogorours theorem;

⇒x²+x² =a²

⇒2x²=a²

⇒x²=a²/2

⇒x=a/√2

Hence the length of its side will be a/√2.

Answer:

The correct answer is

n = 3038

Step-by-step explanation:

Where we have;

We note that 1000! = An even number

Since Even × Even = even

Even × Odd = Even

Also, 7ⁿ is an Odd number since odd × odd = odd

Therefore 7ⁿ will divide 1000! with some fractions as follows;

1000! divided by 7ⁿ

When 7ⁿ = 1000!

log(7ⁿ) = log(1000!) = log(4.02×10²⁵⁶⁷)

n·log(7) = 2567.604

n = 2567.604/(log(7)) = 3038.23

Therefore, the largest integer n such that 7ⁿ divides 1000! = 3038

Which gives, 1000! ÷ 7³⁰³⁸ = 1.5733.

25% increase

Step-by-step explanation:

Apex

The percent increase in Soraya's monthly earnings is 2.5%

Increase expressed as a percentage is referred to as a percentage increase. When comparing growth in a quantity through time, from its beginning value to its ultimate value, the percentage increase formula is utilised.

Given:

Soraya earned $40 in October.

She earned $50 in November.

Change in amount= 50- 40= $10

So, percent increase = 10/ 40 x 100

                                   = 2.5%

Answer: 14000

Step-by-step explanation:

From the question, the first thing is to first calculate the simple interest (S.I). This will be:

S.I = (principal × rate × time)/100

where principal = 10,000

rate = 4%

time = 10 years

Simple interest = (10,000 × 4 × 10)/100

= 400000/100

= 4000

The total value after 10 years will be th addition of the amount invested and the interest. This will be:

= 10,000 + 4000

= 14000

Answer:

b. Sorted and listed from the minimum to the maximum values

Step-by-step explanation:

A percentile can be defined a measure that is made use of statistics.

A percentile is a statistical measure that indicates or shows comparison amongst a given set of data.

A percentile tells us the value or scores below which a percentage of a given observation in a data set falls.

In other to be able to effectively obtain the percentile if a given set of data, the following steps must be taken.

Step 1: Arrange, sort and list the values of the given the data set in order from lowest to the highest

Step 2: Multiply the percentage (also represented by P ) by total number of values in the data set( also represented by N)

Step 3: The value obtained from step 3 is know as the rank and this would helps us to find the percentile f a given data set.

The formula for calculating a percentiles is given as

= (P/100) x N,

where

P = percentile

N = number of values in a data set (sorted or arranged from lowest to highest)

n = Rank of a given value.
