Two angles x and y are complementary - which means their
angles add up to 90 degrees. Angle y is 20 degrees less
than angle x. Find the measure of each angle.
Answer:
X=55° Y=35°
Step-by-step explanation:
X+Y=90°
Y= x-20
(X-20)+X=90°
2X-20=90°
2X=110°
X=55°
55°+Y=90°
Y=35°
Which choice correctly describes this event? Every time I flip a coin / will get tails.
A)Certain
B)Impossible
C)Likely
D)Unlikely
Please help ASAP ill give BRAINLIEST
Answer:
D
Step-by-step explanation:
With each flip of the coin, the chance of it landing on tails is multiplied by half. Hence the chance of landing a consecutive series of tails decreases the more times you flip the coin, but never reaches 0.
A is incorrect as it is possible to land heads on any flip.
B is incorrect as there is always a possibility of landing tails on every flip.
C is incorrect as the chance of getting tails on every flip is small (and gets smaller) and hence cannot be considered to be likely.
Hence D is the answer.

Cora bought 90 feet of cable for $.25.20. She needs 40 more feet. If the unit price is the same, how much will she pay for the extra 40 feet of cable?
Answer: $11.2
Step-by-step explanation:
Given
Cora bought 90 feet cable for [tex]\$25.20[/tex]
So, the price of a foot is the division of rate and length
[tex]\Rightarrow \text{Price P=}\dfrac{25.20}{90}\\\\\Rightarrow P=\$0.28\ \text{per foot}[/tex]
for additional 40 feet, the cost is
[tex]\Rightarrow 0.28\times 40\\\Rightarrow \$11.2[/tex]
Thus, Cora pays $11.2 for extra 40 feet

Find the area of a right triangle whose hypotenuse is 20 units long and the altitude drawn from the Right angle divides the hypotenuse into 5 units and 15 units.
Step-by-step explanation:
the height of the triangle = √(5×15)= √75
=5√3 units
the base of triangle= 20 units
so, the area = ½×20×5√3= 50√3 units
or 86.60 units

given the diagram below, explain how you would determine the opposite, adjacent, and hypotenuse side from the given 35° angle. (HELP PLEASE!!)
Answer:
opposite=8.402402490459 ,adjacent is already given=12, hypotenuse=14.64929507
Step-by-step explanation:
to do this you will have to use the law of sines. the first thing you need to do is solve for the unknown angle by subtracting 90+35 from 180. so you get the equation 180-(90+35)=55. now that you know all your angles, you can use the law of sines to solve for the unknown sides. the law of sines state that a/sin(A)=b/sin(B). if you substitute the values of 12 and 55 into the equation, since you know those sides, you can then find a ration that you can use to find the other sides, 12/sin(55)=b/sin(B), which is equal to, 14.649... Next you pick whichever side you want to solve for next, and plug in its opposite angle (i would solve for the other leg, because then you can use pythagorean theorem to solve for the hypotenuse, so i will demonstrate that way) plug in the angle 35, since it is opposite the leg and then finish for the variable, 14.649...=b/sin(35). once you have the sin, you can multiply it by the 14.649 to get your side, 14.649...*.5736...=8.402...=b. now you have your two legs, so you can use a^2+b^2=c^2 to solve for the hypotenuse. once you plug in your values it should look like this, 12^2+8.402...^2=c^2. which simplifies down to 214.602...=c^2. so you take the square root of both sides to find c, which equals 14.649. you can check that by seeing if 14.649 is bigger then the other two sides, which it is. This number should look familiar because it was the ratio we got when we divided 12 by the sin(55). the reason that happened is because the sin(90) is 1, the 14.649*1=14.649.

The volume of a cylinder is 14,130 ft 3 . If the diameter is 30 feet, calculate the height of the cylinder
Answer:
V = PI*r2h
In plain english the volume of a cylinder can be calculated by squaring the radius, multiplying that value by PI, then multiplying by the height. You can also think of it as finding the area of a flat circle (PI * radius squared) and multiplying by the height to find volume.
Here is a step-by-step case that illustrates how to find the volume of a cylinder with a radius of 3 inches and a height of 5 inches. In this example PI will be 3.14.
V = pi * r2 * h
= pi * 32 * 5
= pi * 9 * 5
= 3.14 * 45
= 141.37 cubic inches
Step-by-step explanation:
The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm.
The height of the cylinder is given by h = 20 feet
What is a Cylinder?A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is
Volume of Cylinder = πr²h
Surface area of cylinder = 2πr ( r + h )
where r is the radius of the cylinder
h is the height of the cylinder
Given data ,
Let the height of the cylinder be h
Now , the volume of the cylinder V = 14,130 feet³
The diameter of the cylinder d = 30 feet
So , the radius of the cylinder r = d/2 = 15 feet
And , Volume of Cylinder = πr²h
On simplifying , we get
14,130 = π( 15 )²h
Divide by 225 on both sides , we get
πh = 62.8
Divide by π on both sides , we get
h = 62.8 / 3.14
h = 20 feet
Therefore , the value of h is 20 feet
Hence , the height of the cylinder is 20 feet

[tex]\frac{4}{12}[/tex] = [tex]\frac{5}{x}[/tex]
solve for x (cross multiply)
Answer:
15
Step-by-step explanation:
CO : CL = OR : LA
* substitute the side letters with the given side lengths *
( let AL = x )
4 : 5 = 12 : x or
[tex]\frac{4}{5} =\frac{12}{x}[/tex]
now we solve for x by cross multiplying
4 * x = 4x
12 * 5 = 60
now we have 4x = 60
step 2 divide each side by 4
4x / 4 = x
60 / 4 = 15
we're left with x = 15
hence LA = 15
