Answer:

b. $5.33

Step-by-step explanation:

one sandwich for 4.47

two salads for 5.10 each, so 10.20 for both;

now add 10.20 and 4.47 together: you get 14.67

the bill comes to 14.67, but he pays 20.00;

so subtract 14.67 from 20; you get 5.33

his change is $5.33

Answer:

Total points= 12,890 points

Step-by-step explanation:

Giving the following information:

For each time Sierra plays, she earns 2,578 points. Therefore, the total point formula is:

Total points= 2,578*x

x= number of games played

Now, we multiply for 5 plays:

Total points= 2,578*5

Total points= 12,890 points

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]

Answer:

2/9 - 1/3 (If you want to solved: -1/9)

Step-by-step explanation:

2 over 9 is 2/9 minus is just -  and 1 over 3 is 1/3 so the equation looks like this: 2/9-1/3

To solve this you need to multiply the 1/3 by 3 on both the denominator and numerator: 2/9-3/9

simplify: -1/9

Answer:

W

Step-by-step explanation:

It is W because the y-intercept is always on the y line.

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

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.

(-3+81)(-3-81)= -6552

Answer:

15.625

Step-by-step explanation:

It's a ratio, just divide 192(Box A volume) by 8(Box A length) to get a third number(24) you then use that number to divide Box B's volume. 375/24 is 15.625

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

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]

Step-by-step explanation:

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

Answer: arc CG=arc CE+ arc EG

Step-by-step explanation:

The arc CG is the sum of arc CE and arc EG option fourth arc CG = arc CE + arc EG is correct.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have a circle shown in the picture.

As we can see the arc CG is marked on a circle.

CG is the sum of CE and EG.

or

arc CG = arc CE + arc EG

Thus, the arc CG is the sum of arc CE and arc EG option fourth arc CG = arc CE + arc EG is correct.

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
