Karina is making accessories for the soccer team. She uses 628.86 inches of fabric on headbands for 45 players and 2 coaches. She also uses 384.30 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
21.92 inches
Step-by-step explanation:
628.86 inches of fabric on headband for 45 players and 2 coaches
Total persons=45 players +2 coaches=47
Each person uses 628.86/47 inches of fabrics
=13.38 inches per person
384.30 inches for wristband for players only
Each player uses 384.30/45 inches of fabrics
=8.54 inches per person
Karina uses 13.38 inches of fabric for headband and 8.54 inches of wristband for each player
13.38+8.54
=21.92 inches of fabric for each player
Perform the following operation:
h(n) = 4n + 5
g(n) = 3n +4
Find (h - g)(n)
Answer:
n+1
Step-by-step explanation:
h(n) = 4n + 5
g(n) = 3n +4
(h - g)(n) = 4n + 5 - (3n +4 )
distribute the minus sign
= 4n +5 - 3n -4
Combine like terms
= 4n -3n +5-4
= n +1

Hi Guys! if anyone can help me with this please do! I need to solve for X and the triangles in each pair are similar.
Answer:
x=6
Step-by-step explanation:
We can use ratios to solve
18 4x+6
--------- = -------------
24 40
Using cross products to solve
18*40 = 24 * (4x+6)
720 = 24*(4x+6)
Divide each side by 24
720/24 = 24/24 (4x+6)
30 = 4x+6
Subtract 6 from each side
30-6 = 4x+6-6
24 = 4x
Divide each side by 4
24/4 = 4x/4
6 = x
sin(90°– x)= - square root 3 over 2 the value of x is
Answer:
x=30
Step-by-step explanation:
Sin 60 = ((√3)/2), so x=90-60. x=30.
The required value of x for function sin(90°– x)= - √3/2 is x =150°.
A function is given as sin(90°– x)= - √3/2, Value of x for the function is to be determined.
What are trigonometric equations?The equation contains trigonometric operators such as sin, cos.. etc. In algebraic operation.
sin(90°– x)= - √3/2
sin(90°– x) = -sin60
90°-x = sin(-60°)
90°-x = -60°
-x = -60°-90°
x = 150°
Thus, the required value of x for function sin(90°– x)= - √3/2 is x =150°.

The reciprocal of the cosine is the ___.
A. secant
B. tangent
C. sine
D. cotangent
Answer:
The correct answer is A
Step-by-step explanation:
The secant is the distance from the center to the vertical tangent in a certain direction.
Answer:
A. secant
Step-by-step explanation:
For trigonometric ratios, we know that cosine is [tex]\frac{adjacent}{hypotenuse}[/tex]. The reciprocal of something is just flipped over. So the reciprocal of cosine is [tex]\frac{hypotenuse}{adjacent}[/tex], which is the ratio for secant.
Another way we can remember this is [tex]sec x = \frac{1}{cos x} \\\\cos x = \frac{1}{sec x}[/tex]

In a certain Algebra 2 class of 20 students, 8 of them play basketball and 7 of them play baseball. There are 8 students who play neither sport. What is the probability that a student chosen randomly from the class plays basketball or baseball?
Answer:
12/20
or
3/5
or
0.6
Step-by-step explanation:
The probability that a student chosen randomly from the class plays basketball or baseball is 3/5.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Total student = 20
let the number who play both = x
So, Number of those who play basketball = 8- x
and, Number of those who play baseball = 8- x
Number of those who played neither = 8
So, 8-x + 7- x + x + 8 = 20
x = 3
Then, Basketball player = 8-3 =5
and, baseball player = 7-3 = 4
Thus, the probability that a student chosen randomly from the class plays basketball or baseball
= (5+ 4 + 3)/ 20
= 12/20
= 3/5

Answer: 68 adult tickets were sold and 78 child tickets were sold.
Step-by-step explanation:
a + c = 146 where a is the number of adults tickets sold and c is the numbe rof child tickers sold.
5.60 a+ 8.80c= 1067.20
a + c = 146
5.60a + 8.80c = 1067.20 solve by elimination.

What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,
y =mx + c, slope intercept form
y - y₁ = m(x - x₁), point-slope form
where,
x and x₁ are the coordinates of the x-axis,
y and y₁ are the coordinates of the y-axis,
m is the slope of the line, and
c is the y-intercept.

Since it is 1$ 5 pencils and 100/5=20, the unit cost is 20 cents
Answer:
the unit price is $0.20 for 1 pencil
Step-by-step explanation:
if u see 5 pencils cost 1 dollars and unit price means the value of one item, so like the cost of 1 pencil
write it as a ration of cost to pencil
the ratio is 1/5
now divided 5 on the top and the bottom to get the unit price
1 divided by 5= 0.2
so now the ratio is 0.2/1

The graph of the function, f(x) = - x2 - 3x + 1, opens and has a, value.
Answer:
downward, maximum value
Step-by-step explanation:
f(x) = - x^2 - 3x + 1
The negative in front of the x^2 means the graph opens downwards
The y intercept is 1
Because it opens downward it has a maximum value
Answer:
Opens downwards and has a maximum value
Step-by-step explanation:
f(x) = -x² - 3x + 1
a is the coefficient of x², which is -1
Since a < 0, it's a concave down graph which opens downwards. Therefore it has a maximum turning point
