In the applet above right triangle XYZ is drawn with a 23 degrees angle. for the right triangles with an angle of 23 degrees the ratio of the leg adjacent the 23 degrees angle compared to the hypotenuse is 0.92 if the leg adjacent to the 23 degrees angle has a length of 46 units, what is the length of the hypotenuse ?
Answers
Answer:
50 ( nearest whole number)
Step-by-step explanation:
Given from the question :
Ratio of Adjacent to hypotenus = 0.92
Length of Adjacent leg = 46 units
From trigonometry :
Ratio of adjacent to hypotenus is the cosine of the angle :
Hence,
Cos 23 = adjacent / hypotenus
Cos 23 = 46 / hypotenus
0.9205048 = 46/ hypotenus
Hypotenus = 46 / 0.9205048
Hypotenus = 49.97

Lines J and k intersect at point Q and h is a straight line. What is the value of X ?
Answers
Answer:
Step-by-step explanation:
Angles on a straight line add up to 180 so 180-135 equals 45. Vertically opposite angles are equal so the second angle inside the triangle equals 100. Henceforth, we can solve this equation:
x +45+100 = 180 (angles in triangle add up to 180)
x+145=180
x=35
Vertically opposite angles are equal so x will become 35.

A cylinder-shaped drainage pipe 66 in. long measures 25.12 in. around.
What is the volume of the drainage pipe?
Answers
Answer:
Step-by-step explanation:
25.12 inches around means diameter. So radius = 12.56 inches
volume [tex]= \pi r^2 \times h =\pi \times 12.56^2 \times 66 = 32709.44 \ in^3[/tex]
Answer:
The volume of the drained pipe is 32692.11 in ³.
Step-by-step explanation:
Given :-Diameter of drainage pipe = 25.12 in
So, radius , r = 25.12 in = 12.56 in
Height of drainage pipe, h = 66 in.
To Find :-Volume of the drainage pipe
Solution :-We know that,
Volume of cylinder = π × r ² × h
substitute the values
Volume of pipe = 3.14 × (12.56 in)² × 66 in
simplify
Volume of pipe =3.14 ×157.7536 in² × 66in
multiplying ✖ the values
Volume of the pipe = 32,692.11 in ³
Therefore, the volume of the drained pipe is 32692.11 in ³.

-8 < x< 3
Step-by-step explanation:
|2x+5| <11
there are two solutions, one positive and one negative ( remember to flip the inequality for the negative)
2x+5 <11 and 2x+5 > -11
Subtract 5 from each side
2x+5-5 < 11-5 and 2x+5-5 > -11-5
2x< 6 and 2x>-16
Divide by 2
2x/2 <6/2 and 2x/2 >-16/2
x <3 and x>-8
-8 < x< 3
x is less than 3 and x is greater than -8

Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for
recycling. Abha collected 178 more cans than Shane did.
Write an inequality to determine the number of cans, S, that Shane could have collected.
What is the solution set of the inequality?
Answers
Answer:
s + 178 = Abha's Can's
Step-by-step explanation:
Well since Abha collected 178 more cans than Shane, it would be Shane's amount of cans they collected AND 178 cans on top of that.
(i didnt know if you wanted the solution of s or just the equation on how to find s)

What is the slope-intercept equation of the line below? A.y=2x+3 B.y=-2x-3 C.y=2x-3 D.y=-2x+3
Answers
Answer:
C.
Step-by-step explanation:
First, lets find the y-intercept. The y-intercept where the line passes through the y-axis. In this case, it is -3.
Now, to find the slope, lets find the next non-decimal point(that way it is easier on us). That would be (1,-1). Now, to get to this point from the y-intercept, we have to go left 1 unit, and up 2 units. So, the change in y over change in x = 2/1 or 2. Now, using this information, we can form the equation:
y = 2x + -3. or y = 2x - 3.

Answer:x=3, x=18, x=29, x=30, x=27
Step-by-step explanation: for problems like the first one, the angles add up to 180 since it’s just a straight line.
The second problem is a right angle so 90°. It gives you 2x and 3x. Part + part =whole so you have 5x=90 then just solve.
Angles across from each other are the same so just 145=5x then solve.

A potential difference of 35v is applied across the ends of a resistance of 3 ohms. How much current will flow in the resistance?
Answers
Answer:
11.67 Amperes
Step-by-step explanation:
From Ohm's law,
Ohm's law which state that a current
which flow through a conductor at a distance between two points is proportional directly to the voltage which is flowing across the two points.
I= V/R
Where
I= Current
V= potential difference =35v
R= resistance = 3 ohms
Then substitute the values we have
I = 35 / 3
I= 11.67 Amperes
