Patrick and his friends Jerome and marina collect football cards. Altogether they have 3000 cards. Patrick has 1533 cards in his collection and Jerome has 837 cards. Which statements about the football cards are correct ?
Answer:
i'm not sure what the statements are but here is some information
p + j + m = 3000
1533 + 837 + m = 3000
m = 630
Marina has 630 cards

QR is a radius of r and PQ is tangent to r. Find the value of x. Please help me!! I am in dire need! What is X?! Thank you for any assistance. :)
Answer:
54
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
Dividing circumference with radius
If you divide the circumference C over the radius r, you get 2pi
2pi = C/r
this is because
C = 2pi*r
is one formula to find the circumference. Another formula is
C = pi*d
which works because d = 2r, ie the diameter is twice the radius.
In the figure below, K lies between J and L. Find the location of K so that JK is 1/7 of JL.
Answer:
-22 is the value of K.
Step-by-step explanation:
A simple way to see how far a mid-point or end-point is from another is by adding or subtracting. For this figure I added to see how many numbers would add twice to get from -15 to -29. -14 is the exact number from -15 to -29; divide that by 2 to get half of -14 which is -7. -7 + (-15) gives you -22.
The location of K so that JK is 1/7 of JL is -22.
Given that, K lies between J and L.
We need to find the location of K so that JK is 1/7 of JL.
What is a line segment?In geometry, a line segment is a part of a line that is bounded by two distinct end points and contains every point on the line that is between its endpoints.
Now, the distance between the points J and L on the number line is 14.
So, 1/7(14)=2

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.
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.

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

Katie has a collection of nickels, dimes and quarters with a total value of $3.95. There are 4 more dimes than nickels and 3 more quarters than nickels, how many of each coin does she have?
Answer:
She has 7 nickels, 11 dimes and 10 quarters
Step-by-step explanation:
Total value =$3.95
Let
Nickel = x
Dimes = x + 4
Quarters = x + 3
Every
Nickel = 5 cents
Dimes = 10 cents
Quarters = 25 cents
Total cents = $3.95 × 100
= $395
5n + 10d + 25q = 395
5(x) + 10(x+4) + 25(x+3) = 395
5x + 10x + 40 + 25x + 75 = 395
40x + 115 = 395
40x = 395 - 115
40x = 280
Divide both sides by 40
x= 280/40
= 7
x= 7
Nickel = x = 7
Dimes = x + 4
=7+4
=11
Quarters = x + 3
=7+3
=10

Tasha was $422.75 last week. Of that paycheck $42.75 was extra overtime pay for 3 hours. If the rest of the check was Tasha’s weekly earnings for 40 hours, what is her weekly per-hour rate?
The solution is $ 9.50
The weekly per hour rate of Tasha is $ 9.50
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The weekly per hour of Tasha last week = $ 422.75
The extra overtime pay of Tasha for 3 hours = $ 42.75
The total number of hours working = 40 hours
So , the equation will be
The weekly per hour of Tasha without overtime = weekly per hour of Tasha last week - overtime pay of Tasha for 3 hours
Substituting the values in the equation , we get
The weekly per hour rate of Tasha without overtime = 422.75 - 42.75
The weekly per hour of Tasha without overtime = $ 380
So , The weekly per hour rate of Tasha A = The weekly per hour rate of Tasha without overtime / total number of hours working
Substituting the values in the equation , we get
The weekly per hour rate of Tasha A = 380 / 40
The weekly per hour rate of Tasha A = $ 9.50
Therefore , the value of A is $ 9.50
Hence , The weekly per hour rate of Tasha is $ 9.50
