The team won 18 of its 30 games. What was the team’s won-lost ratio?
Answer:
18:12 (accurate)
3:2 (simplified)
Step-by-step explanation:
The team won 18 games out of 30 total games. Find the amount of games lost by simply subtracting 18 with 30:
30 - 18 = 12
The ratio you are trying to find is won to lost, or won:lost. Plug in the corresponding numbers to the corresponding terms:
won:lost ⇒ 18:12
18:12 is the ratio.
If the teacher asks you to simplify, factor both sides. Divide 6 from both sides:
(18)/6 : (12)/6
3:2
3:2 is your simplified ratio.

Aunt Martina is pricing cakes for a baby shower she is throwing. She wants one large cake shaped like a duckling and also some cupcakes in pastel colors. Sparrowtown Bakery charges $2 for each cupcake, plus $50 for the large cake. Dakota's Sweet Shoppe charges $44 for the large cake and $4 for each cupcake. If Aunt Martina orders a certain number of cupcakes, the cost will be the same at either bakery. What would the total cost be? How many cupcakes would that include?
Answer:
3 cupcakes
Total of $56
Step-by-step explanation:
First we would need to create an expression for the total of each bakery, which would be the following with x representing the number of cupcakes.
2x + 50
4x + 44
Since we know that the total for both bakeries was the same we can simply make the expressions equal to one another and solve for x.
2x + 50 = 4x + 44 ... subtract 2x on both sides
50 = 2x + 44 ... subtract 44 on both sides
6 = 2x ... divide both sides by 2
3 = x
Finally, we can see that at 3 cupcakes the total for both bakeries will be the same and be a total of
2(3) + 50
6 + 50
$56
What is Cos^-1( -sq2/2)? Pleaseee help ASAPOL
Answer:
s cos^(-1)(-(q^2 s)/2) + sqrt(4 - q^4 s^2)/q^2 + constant
Step-by-step explanation:
Take the integral:
integral cos^(-1)(-(q^2 s)/2) ds
For the integrand cos^(-1)(-(q^2 s)/2), substitute u = -(q^2 s)/2 and du = -q^2/2 ds:
= -2/q^2 integral cos^(-1)(u) du
For the integrand cos^(-1)(u), integrate by parts, integral f dg = f g - integral g df, where
f = cos^(-1)(u), dg = du, df = -1/sqrt(1 - u^2) du, g = u:
= -(2 u cos^(-1)(u))/q^2 + 2/q^2 integral-u/sqrt(1 - u^2) du
Factor out constants:
= -(2 u cos^(-1)(u))/q^2 - 2/q^2 integral u/sqrt(1 - u^2) du
For the integrand u/sqrt(1 - u^2), substitute p = 1 - u^2 and dp = -2 u du:
= -(2 u cos^(-1)(u))/q^2 + 1/q^2 integral1/sqrt(p) dp
The integral of 1/sqrt(p) is 2 sqrt(p):
= (2 sqrt(p))/q^2 - (2 u cos^(-1)(u))/q^2 + constant
Substitute back for p = 1 - u^2:
= (2 sqrt(1 - u^2))/q^2 - (2 u cos^(-1)(u))/q^2 + constant
Substitute back for u = -(q^2 s)/2:
Answer: = s cos^(-1)(-(q^2 s)/2) + sqrt(4 - q^4 s^2)/q^2 + constant

Answer:
I think the answer is 2 4
Step-by-step explanation:
Table {1} and table {2} represent the relations that are functions.
What is function? What is modulus function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
We can define the modulus function as -
|x| = - x {x < 0}
|x| = x {x > 0}
Given is to identify which of the relations are functions.
For a relation to be a function, it should have unique value of {y} for a unique value of {x}. One value of {x} cannot have more than one values at the same time. We can see in the image attached that only table 1 and 2 represent such relations. So, we can conclude that relation {1} and {2} represent the functions.
Therefore, table {1} and table {2} represent the relations that are functions.

The requreid, in the given diagram, we can see a circle, and it is indicated that the center of the circle is L.
What is a circle?The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
Where h, k is the coordinate of the center of the circle on a coordinate plane and r is the radius of the circle.
Here,
In the given diagram, we can see a circle, and it is indicated that the center of the circle is L. The center of a circle is a point that is equidistant from all points on the circumference of the circle. This means that if we draw a line segment from the center to any point on the circumference of the circle, the length of that line segment will be the same as the length of the line segment from the center to any other point on the circumference.
Thus, the requreid, in the given diagram, we can see a circle, and it is indicated that the center of the circle is L.

Answer:
y km = (x+2)y km
Step-by-step explanation:
Given that,
A car covers (x+2) kilometre in 1 litre.
We need to find the distance it will cover in y litres.
1 litre = (x+2) km
y km = (x+2)y km
Hence, it will cover (x+2)y km in y litres.
