Three lemon cookies and two fudge cookies have a total of 400 calories. Two lemon cookies and three fudge cookies have a total of 425 calories. How many calories are in each kind of cookie?
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
Express this number in standard form.

If it took eight men ten hours to build a wall, how long will it take four men?
Answer:
I want to say 20
Step-by-step explanation:
4 is half of 8, so double the time and its 20.........
Since it took 10 hours for 8 men to build a wall. If you had 4 men build a wall it would most likely take twice as long than if there were 8 men due to less people.
So it would take 20 hours for 4 men to build a wall.
in the circle below, the sum of which arcs is equivalent to arc CG?
arc CG = arc CD + arc FG
arc CG = arc CF + arc EG
arc CG = arc CE + arc DG
arc CG = arc CE + arc EG
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.
What is a circle?
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:
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:

2 over 9 minus 1 over 3 in simplest form
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

Susanna deposits $400 in a savings account with an interest rate of 3% compounded annually. What equation could Susanna use to calculate
how many years it will take for the value of the account to reach $600?
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.
How is future value found?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 opening under a bridge is in the shape of a semielliptical arch and has a span of 82 feet. The height of the arch, at a distance of 9 feet from the center, is 28 feet. Find the height of the arch at its center. Hint: let the center of the horizontal span be (0, 0).
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: X = -1/6
Step-by-step explanation:
So what we know is that 3 times something will equal negative one half. Tog get to that number, we divide the 3x by 3 to get x and the same on the other side so 3 divided by -1/2 is 1/6.
The range of g(x)= [[x/2]] is:
A. All real numbers
B. All odd integers
C. All integers
D. All negative numbers
E. All even numbers
The requried range of the given greatest integer function is all integers. Option C is correct.
What are functions?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.

A car can travel 476 miles on 14 gallons of gas. Write a proportion relating the distance to the number of gallons. How many miles can the car travel on 17 gallons?
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
A number has a 6 in the tenths place. The number also has a digit whose value is 1/10 the value of the 6 in the tenths place. Which could be the expanded form of the number?
Answer:
The expanded form of the number is
= 6 × 1/10 + 6 × 1/100
= 6/10 + 6/100
= 0.6 + 0.06
The number is = 0.66
Step-by-step explanation:
A number has a 6 in the tenths place. The number also has a digit whose value is 1/10 the value of the 6 in the tenths place. Which could be the expanded form of the number?
We are told that a number has 6 in its tenth place
This means
6/10 = 0.6
The number also has a digit whose value is 1/10 the value of the 6 in the tenths place.
This means
= 6/10 × 1/10 = 6/100
0.6 × 1/10
= 0.06
Hence, the expanded form
= 6 × 1/10 + 6 × 1/100
= 6/10 + 6/100
= 0.6 + 0.06
= 0.66

x^3-2x^2 +5x-10
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]
