-6 10n to the 5 11n to the 3

you put the ones that are alike to gether. so -3 and -3 together and 5n to the 3rd and 6n to the third together and 3n to the fifth and 7n to the fifth together

Given : (-3 + 3n⁵ + 6n³) + (7n⁵ + 5n³ - 3)

Rearrange respective Like terms as they are a Family, They should be together.

In the Given Expression, The Like terms are :

✿  3n⁵ and 7n⁵

✿  6n³ and 5n³

✿  -3 and -3

After Rearranging, The Given Question looks like :

✿  (3n⁵ + 7n⁵) + (6n³ + 5n³) - 3 - 3

Now, Add the Like Terms as they belong to the same Family

⇒ 10n⁵ + 11n³ - 6

Answer:

Step-by-step explanation:

there are 2 possible values for q

Since sin q > 0 then q is in the first or second quadrant

sin q = 0.4848, then

q = [tex]sin^{-1}[/tex](0.4848) ≈ 29° ← first quadrant

or q = 180° - 29° = 151° ← second quadrant

Answer:

Correct choice is A

Step-by-step explanation:

Note that 6.5% is 0.065 as decimal.

Ramon bought a bicycle for $478. The value of the bicycle is expected to decrease at a rate of 6.5% each year, then the function that represents the situation is

[tex]y=478\cdot (1-0.065)^t=478\cdot (0.935)^t,[/tex]

where t is time (in years).

Options C and D are false, because functions are increasing, option B is false, because this function represents how much will the value decrease.

Answer:

The correct answer is A

f(t)=478(0.935)^t

with (x₁, y₁ ) = (2, - 4) and (x₂, y₂ ) = (2, 6)

d = [tex]\sqrt{(2-2)^2+(6+4)^2}[/tex] = [tex]\sqrt{0+100}[/tex] = [tex]\sqrt{100}[/tex] = 10

Answer:

Step-by-step explanation: My answer would be 36.To figure this out,list all the multiples of 6,9,and 12.Once you do that you have to see which numbers occur in all three.Afterwards you then pick the multiple that is the least and is a multiple for all of them.

Hope this help!!!!!!!!

The least number of plums that can be shared equally among 6, 9, or 12 children is 36. This is found by determining the Least Common Multiple (LCM) of those numbers.

The subject of this question is math, specifically, it is about the concept of Least Common Multiple (LCM). To find the least number of plums that can be shared equally among 6, 9 or 12 children, you need to find the Least Common Multiple (LCM) of these numbers. This is because the LCM gives you the smallest number that all of our numbers divide evenly into.

Here's how you find the LCM of 6, 9, and 12:

Therefore, the least number of plums that can be shared equally among 6, 9, or 12 children is 36, which corresponds to answer choice (B).

Answer:

He saves $14.50

Step-by-step explanation:

We can find the discount by multiplying the price by the percentage off

58* .25  = 14.50

He saves $14.50

Answer:

14.50

Step-by-step explanation:

You are not asked for the final price. You are asked for the amount saved. Don't confuse the two.

If he gets 25% off then you multiply (25/100) times 58 to get the amount saved.

(25/100) * 58 = 14.50

So his reduction is $14.50

Answer:

35% of 90x = 31.5

16x is 9x =

Step-by-step explanation:

35 /100 x 90 = 31.5

Answer:

31.5x; 56.25%

Step-by-step explanation:

For the first question:

We can write 35% as 0.35; this is because 35% = 35/100 = 0.35.  Taking a percentage of a quantity means we multiply; this gives us

0.35(90x) = 31.5x

For the second question:

To find the percentage the second quantity is of the first one, we divide:

9x/16x = 0.5625

This is the same as 56.25%.

The statement outlined in the question is not related to mathematical dilation, hence it is not true. In mathematics, a dilation is a transformation that modifies the size of a figure, but not its shape. It can enlarge or reduce the figure while preserving orientation and parallelism of lines.

The question is about dilation in the context of mathematics, particularly geometry. Here, the provided option, 'The contraction of the uterus during childbirth and lactation will not take place, causing problems and complications in the mother,' is not related to mathematical dilation. So, the statement is not true in a dilation.

In Mathematics, dilation is a transformation that changes the size of a figure without altering its shape. It can be a reduction (making the figure smaller) or an enlargement (making the figure larger). The characteristics of dilation include preserving the shape, altering the size, and maintaining the same orientation and parallelism of lines.

Answer:

$3.38

Step-by-step explanation:

The formula is 45= 8x + 4t. Each tube of toothpaste is 4.50, so times four is 18. So they spent 18 dollars on toothpaste, and the rest on toothbrushes. There are 27 dollars left, and 8 toothbrushes, so divide and each toothbrush is $3.375, or $3.38

Answer:

$3.38  PLEASE GIVE BRAINLIEST

Step-by-step explanation:

4.50(4) + 8x = $45.00

$18 + 8x = 45.00

8x = 45 - 18

8x = 27

x = 27 ÷ 8

x = 3.375 rounded to nearest cent is $3.38

Answer:  Table L shows a proportional relationship.

Step-by-step explanation:

in table L, the ordered pairs are: (-1,-2),(0,0),(1,2),(2,4)

in table M, the ordered pairs are: (-1,-4),(0,0),(1,6),(2,9)

Notice that in table L, the increment for x values is consistent which is adding 1 and the increment for y values is consistent too which is adding 2. That's why table L is proportional.

In table M, the increment for x values is 1 but there is no consistent increment for y values.

Answer:

D. 30-ounce box for $5.25 is the best buy

Step-by-step explanation:

To determine which is the better buy, we need to determine the unit rate for each.  We will take the price and divide by the number of ounces.  The best price is the smallest price per ounce.

A. 10-ounce box for $2.80

$2.80/10 = $.28 per ounce

B. 16-ounce box for $3.75

$3.75/16 = $.234375 per ounce

Rounding to the nearest cent

$.23 per ounce

C. 24-ounce box for $4.50

$4.50/24 = $.1875 per ounce

Rounding to the nearest cent

$.19 per ounce

D. 30-ounce box for $5.25

$5.25/30 =$.175 per ounce

Rounding to the nearest cent

Answer:

E 3960

Step-by-step explanation:

Round 19.9 and 199 to 20 and 200

20*200 = 4000

Now subtract 20

20 * (200-1) = 4000-20

20 * 199 = 4000-20

20*199 = 3980

.1 of 200 is 20

so subtract 20

(20-.1) *200=3980-20

19.9 *200 =3960

(20-.1) *(200-1) = 3960

Answer:

Answer in simplest fraction form is  -22/3

Step-by-step explanation:

We have given,

-29 - (-13 ÷3/5)

we can simplify this as:

i.e   -29 -(-13/(3/5))

or     -29 - (-13 ×5÷3)

or     -29 + 65/3

or      (-87 + 65 )/3

or     -22/3

hence we get fraction in simplest form as -22/3 .

Philadelphia to Gettysburg.                    

Step-by-step explanation:

For Allentown to Gettysburg, the drive is

1hour= 55m

1m = [tex]\frac{1}{55}[/tex]hour

    = 0.018 hour

For Philadelphia to Gettysburg, the drive is

1 hour = 65m

1m = [tex]\frac{1}{65}[/tex]hour

Answer:

Value of p is 1.2.

Now drag and drop the values as per explanation.

Step-by-step explanation:

Additive inverse of any number means a number which can be added to the original number to get

Two numbers are said to be additive inverse of each other if sum of both numbers is 0. For example if 5 is the given number then -5 will be it's additive inverse. So to find additive inverse, we basically change the sign of number.

Given number p is additive inverse off -1.2 so p must be 1.2.

Sum will obviously be 0.

So to graph them on number line, we make a point at -1.2, 1.2 and at 0 for their sum.
