Answer: Lily babysits for less than 4 hours.
Step-by-step explanation:
We can start by multiplying 4 hours by 7/8 to find out how many hours Lily spends babysitting.
4 * (7/8) = 7/2 = 3.5 hours
Since 3.5 is less than 4, Lily babysits for less than 4 hours.
Answer: Less than 4. (3 1/2 hours)
Step-by-step explanation:
When you multiply a number by a number smaller than 1, the answer gets smaller.
Lily babysits for 3 1/2 hours because 4 x 7/8 = 3 1/2

9. A consignment store charges a flat rate plus a percent of the sale price for any items it sells. An item priced at $500 carries a total fee of $120 while an item priced at $800 carries a total fee of $180. Use the point- slope equation to find the total fee for an item priced at $300.
Answer: The total fee for an item priced at $300 is $80.
Step-by-step explanation:
We can use the two given points to find the slope (m) and one point to find the y-intercept (b) of the line representing the consignment fee equation.
We know the two points are (500, 120) and (800, 180)
slope (m) = (y2-y1)/(x2-x1) = (180-120)/(800-500) = 60/300 = 0.2
Now we can use one of the point to find y-intercept (b)
120 = 0.2(500) + b
b = 20
Now we can use point-slope equation to find the total fee for an item priced at $300
y - 120 = 0.2(x - 500)
y = 0.2x + 20

Polynomial Factor Theorem is the subject.
I only need this exercise to finish and I'm very tired, please help.
The zeros of f(x) = 4x³ + 4x² -37x + 44, using the Factor Theorem, are given as follows:
x = -4, x = 1.5 + 0.707i and x = 1.5 - 0.707i.
How to obtain the zeros of the function?The function for this problem is defined as follows:
f(x) = 4x³ + 4x² -37x + 44.
The first linear factor is given as follows:
x + 4 = 0
x = -4 is the first zero.
The Factor Theorem states that the polynomial can be written as a product of it's linear factors.
x + 4 is of the first degree, while the polynomial is of the third degree, hence the remaining linear factors form a second degree polynomial, thus:
(x + 4)(ax² + bx + c) = 4x³ + 4x² -37x + 44.
Then, multiplying on the left side, we have that:
ax³ + (4a + b)x² + (4b + c)x + 4c = 4x³ + 4x² -37x + 44.
Then the coefficients are given as follows:
ax³ = 4x³ -> a = 4.4a + b = 4 -> b = -12.4c = 44 -> c = 11.Inserting these coefficients into a quadratic function calculator, the remaining zeros are given as follows:
x = 1.5 + 0.707i, x = 1.5 - 0.707i.

Answer:
Step-by-step explanation:
The solutions to the equation −2x+2=(1/3)^x+1 can be found by finding the values of x that make the two sides of the equation equal. To solve this equation, we need to find the x values where the graphs of f(x) and g(x) intersect.Since the two functions are not linear and have different forms, it's hard to find the exact solutions. One way to find the solution is to graph the functions and find the x values where the two graphs intersect.It's not possible to find the exact values of x that make the two sides of the equation equal, because the two functions don't intersect at any specific point. It's not possible to find an exact solution to this equation, so none of the options are correct.
Find the size of each internal angle in a regular heptagon. Give your
answer rounded to the nearest degree.
Answer:
Step-by-step explanation:
A heptagon is a polygon with 7 sides.
Sum of all angles of a polygon with n sides = 180(n-2) = 180 x 5 = 900°
So, the degree of each angle will be 900/7 = 128.57 or ≈129°.

Answer: 27,800.0 cm[tex]^{3}[/tex] / 1,696.5 cu in.
Step-by-step explanation:
So Basically, If the Diameter is 12 and the height is 15 inches, the radius will be 6 inches making the Volume of the cylinder 1696.46 cu in.
Now if we were to round that to the nearest place it'd be 1,696.5 cu in.
However, If you want the answer in cm[tex]^{3}[/tex] it would be 27,800 cm making the rounded value 27,800.0 cm[tex]^{3}[/tex].

How to factorize expressions?Factorization, also known as factoring, is the process of breaking a mathematical expression down into its individual factors. In algebra, factorization refers to the process of expressing a polynomial as a product of simpler polynomials, known as its factors.
To factorize an expression, you need to look for factors of that expression. That is:
1. 2l+2w
2l+2w = 2(l + w)
2. -2ab²-4a²b
-2ab²-4a²b = -2ab(b + 2a)
3. 9x²-4
9x²-4 = (3x+2)(3x−2)
4. y²+7x+12
This cannot be factorized
5. 3x²+6x-18

Find the sum the first 5 terms of a G.P whose first term is 3 and its common ratio is 0.25 to 4s.f.
Answer:
A G.P is a sequence of numbers such that the ratio of any two consecutive terms is a constant, called the common ratio. Given the first term (3) and the common ratio (0.25) of the G.P, we can find the sum of the first 5 terms using the formula:
S_n = a(1 - r^n) / (1 - r)
Where:
S_n is the sum of the first n terms of the G.P.
a is the first term of the G.P.
r is the common ratio of the G.P.
n is the number of terms in the sum.
So, to find the sum of the first 5 terms of the G.P, we can substitute the given values into the formula:
S_5 = 3(1 - (0.25)^5) / (1 - 0.25)
S_5 = 3(1 - (0.25)^5) / (1 - 0.25) = 3(1 - 0.25^5) / (1 - 0.25) = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75
S_5 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75
S_5 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.

What is an unsecured loan ?A loan that doesn't require any sort of collateral is known as an unsecured loan. Lenders approve unsecured loans based on a borrower's creditworthiness rather than their assets as collateral. Personal loans, school loans, and credit cards are a few examples of unsecured loans.
Since secured loans are safer for lenders to approve than unsecured loans, unsecured loans need better credit scores.
Jordan most likely made a purchase with her credit card and so the finance agreement she signed would therefore likely be an unsecured loan with no collateral.

Graph the function m(x) = x + 1

How to graph a function ?When graphing a function, you need to remember that x is the independent variable. This means that you need to come up with the values of x and then use these values to come up with the corresponding values of y or m (x ) using the function.
Assuming you have values of x which are -3, -2, -1, 0, 1, 2, 3, the values of y would be:
x = - 3:
= x + 1
= - 3 + 1
= -2
x = - 2

Oversize Transport Inc. supplies custom delivery service for very large construction equipment in the southeast region of United States. The most common lead of the specialty trucker is the Caterpillar model 740 dump truck, which is about 258 feet long. The owner of Oversize Transport, who also drives the firm's single 275-foot-long tractor-trailer rig, chooses to lease this huge piece of capital equipment under a five-year contract requiring monthly lease payments of $5,500 per month. Oversize Transport could not service this profitable market with any rig shorter than 275 feet. A typical delivery takes about a day and a half, so Oversize Transport can make at the most only 20 deliveries per month with its one tractor-trailer rig. Under what circumstances is the tractor-trailer a fixed input? A quasi-fixed input?
Answer:
Step-by-step explanation:
The tractor-trailer rig is a fixed input under the circumstances described because it is necessary for the business to service this profitable market and it cannot be replaced with any other type of capital equipment. The tractor-trailer is a quasi-fixed input because it has a five-year contract that requires monthly lease payments, so it is not completely fixed in the sense that the business can replace it with another piece of capital equipment at any time.
