Answer:
If the slope of a line is negative, it means that the line is sloping downward from left to right. In other words, as the value of x increases, the value of y decreases. This is in contrast to a positive slope, where as the value of x increases, the value of y also increases. So, if the slope of the line y = x is changed to a negative value, the line will still have the same general shape, but it will be flipped upside-down and will slope downward from left to right

The box's volume V expressed as a function of x V(x) =(x+1)(16 -2x) ².
A square form is what?A square has four equal sides, four vertices, and is a closed, two-dimensional object. It has parallel sides on either side. A square is also equivalent to a rectangle having equal length and width.
What are the four different kinds of squares?An equal-length rectangle with two neighboring sides. a quadrilateral having four straight angles and equal sides. a parallelogram with two sides that are equally spaced apart and one right angle. the shape of a right-angled rhombus.
Briefing:A distance of (x+1) is cut in from both sides, so the base dimensions are
18 - 2(x+1) = 16 - 2x
The depth of the fold is (x+1), so that is the depth of the box.
The volume V(x) = (x+1)(16 -2x)²

When Derrick turned 15, his grandparents put $10,000 into an account that yielded 1.4% interest, compounded quarterly, When Derrick turns 18, his grandparents
will give him the money to use toward his college education. How much does Derrick receive from his grandparents on his 18th birthday?
=======================================================
Explanation:
The compound interest formula is
A = P*(1+r/n)^(n*t)
where,
A = account balance after t yearsP = deposit amountr = annual interest rate in decimal formn = number of times the money is compounded per yeart = number of yearsThe deposit amount is P = 10000 dollars.
The value of r here is r = 0.014 which is the decimal form of 1.4%
n = 4 since we're compounding quarterly, i.e. 4 times a year.
The timespan from when Derrick was 15 to when he became 18 is 18-15 = 3 years, which is the value of t.
Summary of input values:
P = 10000r = 0.014n = 4t = 3Let's find the value of "A".
A = P*(1+r/n)^(n*t)
A = 10000*(1+0.014/4)^(4*3)
A = 10428.1800719861
A = 10428.18

the value of arc length = 3.14 and the area of the sector = 4.71cm²
What is area of sector and length of an arc?The formula for the area of the sector of a circle is /360° (r2) where r is the radius of the circle and is the angle of the sector.
Arc length is the distance between two points along a section of a curve. It is given as
/360°×2r
= 180°, therefore /3 = 180/3= 60°
arc length = 60°/360 × 2×3.14×3
arc length = 3.14cm
The area of the sector = /360°×r²
60/360×3.14×3²
sector area = 3.14×3÷2
sector area = 4.71cm²
therefore the length of the arc and the area bounded by the arc and radius(sector) is 3.14cm and 4.17cm².

Lilah invested $400 in the stock market. She saw an 8% decrease in her money, what is the value of her stocks now
The value of Lilah's stock after the decrease of 8 % is $ 368
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the initial amount of money Lilah invested in stocks be = A
The value of A is = $ 400
Now , the percentage decrease in the value of stocks = 8 %
So , the equation will be
The value of the stocks after the decrease = initial amount of money Lilah invested in stocks - ( percentage decrease in the value of stocks x initial amount )
Substituting the values in the equation , we get
The value of the stocks after the decrease = 400 - ( 8/100 ) x 400
The value of the stocks after the decrease = 400 - ( 8 x 4 )
The value of the stocks after the decrease = 400 - 32
The value of the stocks after the decrease = $ 368
Therefore , the value of A is $ 368
Hence , The value of Lilah's stock after the decrease of 8 % is $ 368

Answer:
1.8 cans of paint are needed
Step-by-step explanation:
A large statue has a volume of 135 m³ and an area of 81 m², while a small statue has a volume of 5 m³. You want to know the number of cans of paint required to paint the small statue, if each can covers 5 m².
Scale factorThe ratio of linear dimensions on the small statue to those on the large statue is the cube root of their volume ratio:
sf = ∛(5/135) = ∛(1/27) = 1/3
AreaThe area of the small statue is the larger statue's area multiplied by the square of the scale factor:
smaller area = larger area × (sf)²
smaller area = (81 m²)(1/3)² = 9 m²
PaintEach can of paint covers 5 m², so the number of cans required is ...
(9 m²)/(5 m²/can) = 1.8 cans
You will need 1.8 cans of paint to paint the small statue.

If you must pay for whole cans of paint, you must buy 2 cans of paint.

Jayden is deciding between two truck rental companies. Company A charges an initial fee of $85 for the rental plus $1.50 per mile driven. Company B charges an initial fee of $65 for the rental plus $2.50 per mile driven. Let AA represent the amount Company A would charge if Jayden drives xx miles, and let BB represent the amount Company B would charge if Jayden drives xx miles. Write an equation for each situation, in terms of x,x, and determine which company would be cheaper if Jayden needs to drive 5 miles with the rented truck.
Answer:
A = 85 +1.50xB = 65 +2.50xB is cheaper for 5 milesStep-by-step explanation:
You want cost equations and the cheaper company for driving 5 miles when A charges $85 plus $1.50 per mile, and B charges $65 plus $2.50 per mile.
(a) EquationsIn each case, the cost is the sum of the initial fee and the mileage charge. The mileage charge is the cost per mile, multiplied by the number of miles (x). Using the given fees and costs per mile, we have ...
A = 85 +1.50x
B = 65 +2.50x
(b) Cheaper companyThe difference in fees is $85 -65 = $20. The difference in mileage charges is $2.50 -1.50 = $1.00 (per mile). Then the two companies will charge the same for $20/($1 /mile) = 20 miles.
Five miles is less than that "break even" mileage, so the cheaper company will be the one with the lower initial fee. (The graph shows the charges for each company for 5 miles.) For more than 20 miles, the cheaper company is the one with the lower mileage charge.
Company B will be cheaper for a drive of 5 miles.
a Ferris wheel can accommodate 35 people in 20 minutes. how many people could ride the Ferris wheel in 6 hours
Answer:
630 people could ride the Ferris wheel in 6 hours.
Step-by-step explanation:
First, let's find the people-per-hour amount:
Since there are 3 "20 minutes" in an hour, we multiply the amount it can accommodate by 3 as well:
35 * 3 = 105
Next, since we have 6 hours, we multiply our people-per-hour by 6:

Emika has a monthly budget for her cell phone bill.
Last month she spent `120\%` of her budget, and the bill was `\$60`.
What is Emika’s monthly budget?
Using percentages, we know that Emika's monthly budget is $50.
What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it.
A % is a number without dimensions and without a standard measurement.
For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).
So, if we multiply a fraction of a number by 100, you get a percentage. % is the symbol used to denote percentages.
Let x stand in for Emika's monthly cell phone budget.
Divide $60 by 120% to find his monthly spending limit.
x = $60 / 120%
x = $60 / 1.20
x = $50
Therefore, using percentages, we know that Emika's monthly budget is of $50.
