Answer:
2y^6 +12y^4 +5y^3 +30y
Step-by-step explanation:
Given:
rectangle height: 2y^3 +5
and width: y^3+6y
Find:
the area as a polynomial
Solution:
The area is the product of height and width:
A = (2y^3 +5)(y^3 +6y)
A = (2y^3)(y^3 +6y) +5(y^3 +6y)
A = 2y^6 +12y^4 +5y^3 +30y . . . . area of the rectangle
The area of the rectangle, given the height 2y^3+52y and the width y^3+6y, is calculated by multiplying these expressions together. In standard form, the area is 2y^6+64y^4+312y^2.
Explanation:The question pertains to the calculation of the area of a rectangle given the expressions for its height and width. The area of a rectangle is calculated by multiplying its height and width together.
The given height of the rectangle is 2y^3+52y and the width is y^3+6y. Therefore, to calculate the area, we multiply these two expressions together. Using distributive properties of multiplication over addition, we get:
Area = (2y^3+52y) * (y^3+6y)
=
2y^6+12y^4+52y^4+312y^2
So, the area of the rectangle in standard form is 2y^6+64y^4+312y^2.

Question 2 - Brianna spends 7 3/5 hours in school each day. Her lunch period is 30
minutes long, and she spends a total of 42 minutes switching rooms between classes.
The rest of her day is spent in 6 classes that are all the same length. How long is each
class?
Answer:
64 minutes
Step-by-step explanation:
7⅗ hours = 7⅗ × 60 min
= 38/5 × 60
= 456 minutes
456 - 30 - 42 = 384 minutes for 6 classes
384/6 = 64 minutes per class
Please help. 3. What is the approximate perimeter of △ABC?
15 units is wrong btw, I already tried that.
The perimeter of a triangle is the sum of the lengths of all the sides of a triangle. The perimeter of the given triangle ABC is 14.2 units.
Distance between two points x and y can be calculated using the formula : √(x²+y²)
∴ Length of AB =[tex]\sqrt{(3-(-1))^{2}+(4-1)^{2} }[/tex]= [tex]\sqrt{4^{2} +3^{2} }[/tex] = 5
Length of BC = [tex]\sqrt{((-1)-(-2))^{2}+(1-5)^{2} }[/tex] = [tex]\sqrt{1^{2}+(-4)^2 }[/tex] = √17
Length of AC = [tex]\sqrt{(3-(-2))^{2}+(4-5)^{2} }[/tex] = [tex]\sqrt{5^{2}+(-1)^2 }[/tex] = √26
Perimeter of triangle ABC = Length of AB +Length of BC + Length of AC
= 5 + √17 +√26
= 5 + 4.123 + 5.099
= 14.222
≅ 14.2
Therefore, the approximate perimeter of ΔABC is 14.2 units.

Ever since Renata moved to her new home, she's been keeping track of the height of the tree outside her window.
H represents the height of the tree (in centimeters),
t years since Renata moved in.
H=210+33t
How fast does the tree grow?
Answer:
33 cm/year
Step-by-step explanation:
H = 33t + 210
Slope= 33
Slope is also the rate or change:
Growth rate: 33 cm per year
Answer:
Consider the given function:
[tex]h(t)=210+33t[/tex]
From the linear function, 210 is the height of the tree from whenever Renata moved to her new home, and 33 states that the tree grows 33 cm per year.

Work out the percentage change when a price of £20 is increased to £50.
Answer:
The percentage change from 20 to 50 is 150 %
Step-by-step explanation:
(50 - 20) / 20) * 100 = 150 %
Answer:
150%
Step-by-step explanation:
Let's say the 20 increased by x%. Then, we can write the equation:
20 + x% * 20 = 50
Notice that both terms on the left side have 20, so we can factor this out:
20 * (1 + x%) = 50
Divide both sides by 20:
1 + x% = 50/20 = 2.5
Subtract 1 from both sides:
x% = 1.5
Remember that % simply means "out of 100", so x% = x/100:
x/100 = 1.5
Multiply both sides by 100:
x = 150
Thus, the percent increase is 150%.

Your sister helped you get a dream job at a designer clothing store and one of the perks of the job is that you get 15% off all clothing that you buy at their store. During your first month of employment you purchased $235 tax-free (before the discount) worth of clothing from the designer store. You worked 25 hours during that month at $9.50 an hour and they deducted 15% of your total paycheck for deductions. Did you still make money in your first month of employment regardless of how much you spent at their store for designer clothes? How much? Show your work.
Answer:
$197.30 revenue.
Step-by-step explanation:
As long as we realise that 15% = $237.50 total revenue - 15% of that revenue $40.20 and the other 15% was totaled prior and kept to one side as seen as expenditure.
revenue = r clothing purchase = p
r = (25 x 10 -12.50) - (p15% of e235)
r = (250 - 12.50) -( e235- p23.5 +11.73)
r = (237.50) - (expenditure 235- p35.73)
r = 237.50 -(expenditure 199.27)
r= 237.50
e = 199.27
p = 35.73
Answer with out including expenditure your sister revenue was $237.50
The 15% deduction cannot be confused with the deduction from clothes.
If we were to calculate 15% of $237.50 this would be 23.7+ 16.85 =$40.2
A different Salary related 15% contribution payments = $40.20
If these were taken from $237.50
Then $237.50- $40.20 = $197.30 revenue, but we do not have to show expenditure in the total only the workings, which is still owed being $199.27- $40.20 already paid towards.
Extension = This means because $40.20 was deducted then expenditure still to be deducted outside of the question would be e. $199.27 - $40.20 = 159.07 still owed. Saying that the 15% was to pay your sisters contribution to the clothes and not to the state.

The scores of a dart game are 46, 25, 33, 56, 31, 46, 49, 55, a, b, and c. If 33 is the only mode, 46 is the median, and a>c, what is the possible range of values for a?
The possible range of values for 'a' in the dart game score sequence, considering 46 as the median and 33 as the mode, is from 47 to 55.
Explanation:In the list of dart game scores 46, 25, 33, 56, 31, 46, 49, 55, a, b, and c, with the information that 33 is the mode, 46 is the median, and a > c, we can deduce the following:
As 46 is the median in a list of 11 scores, it is the 6th score when the list is ordered. Thus, there must be four scores greater than 46 which are 49, 55, a, and b assuming that b also must be greater than or equal to 46 as a > c and a and b are both greater than c.
Since 46 is not a mode, there cannot be a third instance of it among the scores a, b, or c. This implies a and b cannot be 46. Therefore, a has to be at least 47.
Now, we also know that a is greater than c, but we do not have any other scores to compare c with. Given that we don't know if c is greater than 46, 46 could potentially be c that would make a at least 47, thus the range of possible values for a starts from 47 to any number greater than that but not 56 as the next score after 55 is 56 which is not a as a > c. Therefore, a could technically be any score above 47 that is less than 56, so the range for a is 47 to 55.

what is -5x+-33x x= what
Answer: -38x
Step-by-step explanation: We will be solving for x.
Since both values in the equation have a variable of x, simply add -5x to -33x.
x is already simplified so we can not technically solve for it.
-5x + (-33x) = -38x (We could add the two values since they are equivalent, but we can not solve for x.)
For each inequality, write all one-digit integers that satisfy it.
k>0
Final answer:
To find all one-digit integers satisfying the inequality k > 0, we list every positive one-digit integer from 1 to 9, as these are the numbers that are greater than zero and meet the conditions of the inequality.
Explanation:
The question asks to identify all one-digit integers that satisfy the inequality k > 0. This inequality means that k must be greater than 0. Since we are only considering one-digit integers, we need to list all the numbers from 1 to 9, as these are the positive one-digit integers.
1
2
3
4
5
6
7

9
Each of these numbers is greater than 0 and thus satisfies the inequality k > 0. Numbers that are zero or negative do not meet the requirement of the inequality.

If you have to check whether a number is a solution of a given equation, just plug that number in the equation and see if you get something true or false.
For example, the first option claims that -2 and 6 are solutions to the equation.
Let's check it! If we substitute [tex]x=-2[/tex] in the equation we get
[tex]3(-2)^2-34(-2)-24 = 12+68-24=56 \neq 0[/tex]
So, -2 isn't a solution to this equation. Let's check 6:
[tex]3(6)^2-34(6)-24 = 108-204-24=-120 \neq 0[/tex]
So, 6 isn't a solution either.
Keep going like this and you'll find the correct set of solutions.
Answer:
{ - [tex]\frac{2}{3}[/tex], 12 }
Step-by-step explanation:
We can solve the equation by factoring it
3x² - 34x - 24 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 × - 24 = - 72 and sum = - 34
The factors are - 36 and + 2
Use these factors to split the x- term
3x² - 36x + 2x - 24 = 0 ( factor the first/second and third/fourth terms )
3x(x - 12) + 2(x - 12) = 0 ← factor out (x - 12) from each term
(x - 12)(3x + 2) = 0
Equate each factor to zero and solve for x
x - 12 = 0 ⇒ x = 12
3x + 2 = 0 ⇒ 3x = - 2 ⇒ x = - [tex]\frac{2}{3}[/tex]
Thus the solution set is { - [tex]\frac{2}{3}[/tex], 12 }
