From the question, we are informed that Francis had math homework 18 out of the 30 days in the month.

For us to get the value that is equivalent to the fraction of days she had math homework, we can reduce the fraction to its lowest term. Therefore,

18/30 = 2/5

2/5 is an equivalent fraction.

Answer:

2x - y = 4

Step-by-step explanation:

The base line is 2x + 4y = 1.  To obtain a general formula for lines perpendicular to this "standard form" equation, interchange  and y and replace the '1' with 'C:'

2y - 4x = C

Since the line in question passes through the point (6, 8), we substitute 8 for y and 6 for x, obtaining:

2(8) - 4(6) = C.  Then C = 16 - 24, or  = -8.

The desired equation is

2y - 4x = -8, or

4x - 2y = 8, or (after reduction)

2x - y = 4

The equation that Susanna could use to calculate how long it would take for the account to reach a value of $600 is 600=400(1.03)^x.

Future value is calculated as:

= Amount x (1 + rate) ^ number of years

If the number of years is to be found and the future value is already known, then the number of years can be x:

600 = 400 x (1 + 3%) ^ number of years

600 = 400(1.03)^x

Answer:

its mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.

Answer:

28.7 feet

Step-by-step explanation:

The equation of a parabola is in the form:

[tex]\frac{x^2}{a^2}+ \frac{y^2}{b^2}=1\\ \\where\ (\pm a,0)=major\ axis,(0,\pm b)=minor\ axis[/tex]

The bridge can be represented as:

Since the width of the bridge is 82 feet, therefore 2a = 82, a = 41

[tex]\frac{x^2}{41^2} +\frac{y^2}{b^2}=0\\ \\The\ point\ (9,28)\ lie\ on \ the\ ellipse\ hence\ substituting:\\\\\frac{9^2}{41^2} +\frac{28^2}{b^2}=1\\\\0.048+\frac{28^2}{b^2}=1\\\\\frac{28^2}{b^2}=1-0.048=0.952\\\\b^2=824\\\\b=\sqrt{824}\\ \\b=28.7 \\\\[/tex]

The requried range of the given greatest integer function is all integers. Option C is correct.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Given expression  g(x)= [[x/2]],
Since the given expression is the greatest integer function so the range of the function will be all integers as given as,
For example,
x = 3
g(x) = [[x / 2]]
g(3) = [[3 / 2]]
     = [1.5]
     = 2    [since for greatest integer function [x] = x + 1 or = x]

Thus, the requried range of the given greatest integer function is all integers. Option C is correct.

Answer:

Step-by-step explanation:

Answer: x = [tex]\sqrt{5} , -\sqrt{5}[/tex] , and 2

Step-by-step explanation:

in the first two monomials you can factor out x^2, and on the last pair of two monomials you can factor out 5

so, x^2(x-2)+5(x-2)

some rule out there says you can simplify this to

(x^2+5)(x-2)

to find the zeroes, set it equal to zero

(x^2+5)(x-2) = 0

you can split up the pairs of parenthesis to equal 0

(x^2+5) = 0

(x-2)=0

find x for both equation and you end up with [tex]\sqrt{5} , -\sqrt{5} , and 2[/tex]

Answer:

lemon cremes contain 70 calories. fudge cookies contains 95 calories

Step-by-step explanation:

Let x represent the amount of calories in lemon cremes.

Let y represent the amount of calories in fudge cookies.

Three lemon cremes plus two fudge cookies have 400 calories. This means that

3x + 2y = 400 - - - - - -- - - - -1

Two lemon cremes plus three fudge cookies have 425 calories. This means that

2x + 3y = 425- - - - -- - - - - - 2

Multiplying equation 1 by 2 and equation 2 by 3, it becomes

6x + 4y = 800

6x +9y = 1275

Subtracting,

-5y = - 475

y = - 475/- 5

y = 95

Substituting y = 95 into equation 1, it becomes

3x + 2×95 = 400

3x = 400 - 190 = 210

x = 210/3 = 70

x = 70

Answer:

a) The inequality representing the number of cases he can take =

180 + 47c ≤ 2700

b) 53 cases

Step-by-step explanation:

A worker is taking cases of screws on a lift. Each case weighs 47 pounds and the worker weighs 182 pounds. the lift

has a weight limit of 2700 pounds

a) Write an inequality that describes the number of cases he can safely take on each trip.

Let us represent the number of cases as c

hence,

180 + 47 × c ≤ 2700

= 180 + 47c ≤ 2700

b) What is the maximum amount of cases he can take?

The maximum amount of cases he can take =

180 + 47c ≤ 2700

180 + 47c = 2700

Collect like terms

47c = 2700 - 180

47c = 2520

c = 2520/47

c = 53.617021277 cases

c = 53 cases

The maximum number of cases he can carry is 53 cases

Answer:

578 miles

Step-by-step explanation:

In order to solve this problem, we need to first calculate how many miles the car can travel on a single gallon of gas. To do this we simply divide the 476 miles that the car travelled by the 14 gallons it used to do so.

476 miles / 14 gallons = 34 miles per gallon

Now, we can see that car can travel 34 miles for every gallon of gas it uses. Therefore, in order to calculate the distance, it can travel on 17 gallons, we simply multiply 34 miles by the 17 gallons we will use like so...

34 miles * 17 gallons = 578 miles
