Answer:
FG=138
Step-by-step explanation:
Since 23 is a prime number, the only factors of it are 1 and 23.
Which means E is either 1 or 23.
Since 23 is not a factor of 6, E=1. Therefore, G= 23. And, F=6.
So, FG=23*6, which means FG=138.

Step-by-step explanation:
The Pythagorean theorem applies.
(x +36)^2 = 72^2 + x^2
x^2 +72x +1296 = x^2 +5184
72x = 3888 . . . . . . subtract x^2+1296
x = 54 . . . . . . . . . . . divide by 72
A phone call costs $0.58 per minute for the first three minutes and $0.15 per minute for each additional minute. If the total charge for the call was $4.29, how many minutes long was the call Explain the answer in terms of the problem. Show all work.
Answer:
20 minutes
Step-by-step explanation:
.58 times 3 equal 1.74
4.29 - 1.74 = 2.55
2.55 divided by .15 = 17

The area of the square base is S(x), where x is the length of the concrete foundation, and the area of the base of the cylindrical tank is C ( r ), r is the radius of the cylindrical tank. What does the expression S ( C ( r ) ) represent?
Answer:
C(r) is the area of the base of a cylindrical tank with radius r.
We know that this area is:
C(r) = pi*r^2
S(x) is the area of the square base where x is the side length of the base.
S(x) = x*x
Now, we have the expression:
S( C(r)) wich means that we are evaluating the function S(x) in the point x = C(r)
Now, we have a problem here.
In S(x), S(x) is in units of area, and x is in units of length.
And the same for C(r), C(r) is in units of area, and r in units of length.
then we can not have x = C(r)
Then this expression does not represent anything, because the units do not match, so it has no physical sense.
12 people can comfortably fit in a 5 x 5 foot square. Use this value to estimate the size of a crowd that is 8 feet deep on both sides of the street along a 2 mile section of a parade route.
Answer:
40,550
Step-by-step explanation:
Given that 12 people can comfortably fit in a 5 × 5 foot square
Area of square = 5²= 25 ft²
The dimension Given by : 8 feets depth on both sides along a 2 mile section signifies a rectangular area.
Area of rectangle = (length × width)
Recall :
1 mile = 5280 feets
2 miles = 5280 × 2 = 10,560 feets
Area = 8 × 10560 = 84480 sq feets
84480 / 25 = 3379.2
Estimated number of people will be :
3379.2 × 12 = 40,550.4
Hence, estimated number of people = 40,550
Ron asked 18 classmates whether they prefer granola bars over muffins. he used a calculator to compare the number of classmates who said yes to the total number he surveyed. the calculator showed the result as 0.66666667. how many students prefer granola bars over muffins?
Explanation:
Multiply 0.66666667 with 18 to get
0.66666667*18 = 12.00000006
The 6 at the very end is due to rounding error. In reality the 6's in 0.66666667 should go on forever. That 7 is from rounding up.
Anyways, the result 12.00000006 should be 12 exactly.
Note how
12/18 = 0.66666667
when using a calculator.
Answer:
12
Step-by-step explanation:
Use equilvalent fractions 0.6 repeating is 2/3 than convert it over 18 students which is equal to 12/18 students chose granola bars.

Which choice correctly explains which product is the better buy? Coffee Brand A is sold for $6.99 per pound Coffee Brand B is sold for $5.69 for 12 ounces Question 1 options: A Coffee Brand A is a better buy because its unit rate is $2.29 per ounce B Coffee Brand A is a better buy because its unit rate is $0.44 per ounce C Coffee Brand B is a better buy because its unit rate is $2.11 per ounce D Coffee Brand B is a better buy because its unit rate is $0.47 per ounce.
Answer: Choice B
Coffee Brand A is a better buy because its unit rate is $0.44 per ounce
=======================================================
Explanation:
Brand A is sold for $6.99 per pound, which is the same as saying $6.99 per 16 ounces. The unit rate is 6.99/16 = 0.436875 = 0.44 dollars per ounce
Brand B is sold for $5.69 for 12 ounces. The unit rate is 5.69/12 = 0.47416 = 0.47 dollars per ounce
Brand A is cheaper per ounce compared to brand B.
------------------
Here's another way we can look at it
Brand A is $6.99 per 16 ounces. We can set up the equation below
6.99 dollars = 16 ounces
then divide both sides by 16 to turn "16 ounces" into "1 ounce"
So,
6.99 dollars = 16 ounces
6.99/16 dollars = 16/16 ounces
0.436875 dollars = 1 ounce
0.44 dollars = 1 ounce
is the unit rate for brand A.
Similar steps would happen with brand B as well.

how can you reflect a point over the y axis without graphing it?
Answer: You switch the point in the x-axis to the negative/positive of the number.
Step-by-step explanation:
So for example if you have the point (3,7), you would switch the 3 to -3 and you would keep the y the same.

20 points Without solving the systems, determine if there is 0, 1 or infinite solutions. Explain how you know.
Answer:
Infinite Solutions.
Step-by-step explanation:
3x+2y=8 for x:
3x+2y=8
3x+2y+−2y=8+−2y(Add -2y to both sides)
3x=−2y+8 3x 3 = −2y+8 3 (Divide both sides by 3)
x= −2 3 y+ 8 3
Substitute −2/3y + 8/3 for x in 4.5x+3y=12:
4.5x+3y=12
4.5( −2/3y+ 8/3 )+3y=12
12=12(Simplify both sides of the equation)
12+−12=12+−12(Add -12 to both sides)
0=0
Infinitely many solutions.
Answer:
Infinite Solutions.
Step-by-step explanation:
3x+2y=8 for x:
3x+2y=8
3x+2y+−2y=8+−2y(Add -2y to both sides)
3x=−2y+8 3x 3 = −2y+8 3 (Divide both sides by 3)
x= −2 3 y+ 8 3
Substitute −2/3y + 8/3 for x in 4.5x+3y=12:
4.5x+3y=12
4.5( −2/3y+ 8/3 )+3y=12
12=12(Simplify both sides of the equation)
12+−12=12+−12(Add -12 to both sides)
0=0
Infinitely many solutions.
