Answer:
the probability of rolling an even number on a die, then tossing a head on a coin.Answer:
Step-by-step explanation:
The favorable outcome is rolling a five, and that can only occur once using one die. The total number of outcomes is six, since the die is 6-sided. So the probability of rolling a five is 1/6. 2) What is the probability that you will pull a heart out of a standard deck of cards?
Steel chain costs $0.75 per foot from Company
X, which provides free shipping. The same
steel chain costs $1.20 per yard at Company Y,
which charges a $120.00 shipping fee for all
orders. How much more does Company
Y charge, in dollars, than company X for 300
feet of steel chains?
Answer:
Company Y charges 255 dollars more then Company X :)
Step-by-step explanation:
Company X: 0.75 * 300 = 225 + 0 shipping
Company Y: 1.20 * 300 = 360 + 120 shipping = 480
480 - 225 = 255
Brian scored 120 on his test the first time he took the test. The second time he took the test,
he scored 150. By what percentage did Brian increase his score?
a. 20%
b. 25%
c. 80%
d. 125%
Answer:
b. 25%
Step-by-step explanation:
(new - old)/ old * 100%
150 - 120 = 30 ... 30/120 = .25 * 100% = 25%
Answer:
25% increase
Step-by-step explanation:
Take the new amount and subtract the original amount
150-120
30
Divide this by the original amount
30/120
1/4
.25
Multiply by 100%
25%

Answer:
Always
Step-by-step explanation:
When two planes never intersect, they must always be parallel.
The answer can't be sometimes since planes can't sometimes intersect and be parallel.
The answer can't be never because two planes that are never parallel will intersect.
Therefore, two planes that do not intersect must always be parallel.
Answer:
Always parallel
Step-by-step explanation:
Parallel lines never intersect. Think of it like a never ending train track that goes only in a straight line. The two tracks will never cross each other!

Answer:
Sin 73 = 0.956304756, Cos 17 = 0.956304756
Sin 18 = 0.3090169944, Cos 72 = 0.3090169944
This only works when the Sin angle and the Cos angle are complementary, meaning they add up to 90 degrees.
55+35=90
30+60=90
15+75=90
73+17=90
18+72=90
(Keep in mind the values for the Sin and Cos are approximations)

Find the image of the given point
under the given translation.
P(-7,1) T(x,y) = (x + 9, y-3)
P' = ([?], []).
Answer:
P' = (2, -2)
Step-by-step explanation:
You have the x-value and the y-value of the pre-image, so all you have to do is plug that into the translation statement (x + 9 , y - 3).
Since x = -7 and y = 1 that would be (-7 + 9, 1 - 3), or (2, -2).

prove that : cos3A+cos5A+cos7A+cos15A= 4cos4Acos5Acos6A
Answer:
see explanation
Step-by-step explanation:
Using the sum to product identity
cosx + cosy = 2cos([tex]\frac{x+y}{2}[/tex] )cos( [tex]\frac{x-y}{2}[/tex] )
Consider left side
(cos5A +cos3A) + (cos15A + cos7A)
= 2cos([tex]\frac{5A+3A}{2}[/tex] )cos([tex]\frac{5A-3A}{2}[/tex] ) + 2cos( [tex]\frac{15A+7A}{2}[/tex]) cos( [tex]\frac{15A-7A}{2}[/tex] )
= 2cos([tex]\frac{8A}{2}[/tex]) cos([tex]\frac{2A}{2}[/tex]) + 2cos([tex]\frac{22A}{2}[/tex] )cos([tex]\frac{8A}{2}[/tex] )
= 2cos4AcosA + 2cos11A cos4A ← factor out 2cos4A from both terms
= 2cos4A( cos11A + cosA) ← repeat the process
= 2cos4A( 2cos([tex]\frac{11A+A}{2}[/tex] )cos([tex]\frac{11A-A}{2}[/tex] )
= 2cos4A(2cos([tex]\frac{12A}{2}[/tex])cos([tex]\frac{10A}{2}[/tex] )
= 2cos4A(2cos6A cos5A)
= 4cos4Acos5Acos6A
= right side , thus verified

Select the point that is a solution to the system of inequalities.
y< x2 + 6
y> x2 - 4
The only point that is a solution to the system of inequalities is (C) (2, 6).
How to determine inequalities?To solve this problem, substitute each of the points into the inequalities.
For point (A), y < (4)² + 6 and y > (4)² − 4.
This simplifies to y < 22 and y > 12.
However, 2 is not greater than 12, so (A) is not a solution.
For point (B), y < (0)² + 6 and y > (0)² − 4.
This simplifies to y < 6 and y > −4.
However, 8 is not less than 6, so (B) is not a solution.
For point (C), y < (2)² + 6 and y > (2)² − 4.
This simplifies to y < 10 and y > 0.
6 is less than 10 and greater than 0, so (C) is a solution.
For point (D), y < (−2)² + 6 and y > (−2)² − 4.
This simplifies to y<2 and y>−8.
-4 is not greater than -8, so (D) is not a solution.
Therefore, the only point that is a solution to the system of inequalities is (C).

rational or irrational? and why
Answer:
Irrational
Step-by-step explanation:
If we evaluate the square root, we realize that the number will not be a perfect square.
Since it is not a perfect square, it will be an unending, never-repeating, decimal.
Therefore, it will be irrational.
If the ratio of x+y to x-y is 2/5, what's the ratio of y to x ?
9514 1404 393
Answer:
y/x = -3/7
Step-by-step explanation:
Write the given relationship and solve for y/x.
(x +y)/(x -y) = 2/5
5(x +y) = 2(x -y) . . . . . multiply by 5(x-y)
5x +5y = 2x -2y . . . . . eliminate parentheses
7y = -3x . . . . . . . . . . . add 2y-5x

Area = 35 cm^ 2
Step-by-step explanation:
Area = 1/2(a+b) x h

= 35 cm^ 2
Answered by G a u t h m a t h
Answer:
A = 35 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂)
where h is the perpendicular height between the bases and b₁, b₂ are the bases.
Here h = 5 , b₁ = 9 and b₂ = 5 , then
A = [tex]\frac{1}{2}[/tex] × 5 × (9 + 5) = 2.5 × 14 = 35 cm²
