Answer:
Step-by-step explanation:
Probability of of winning next shot if he scores= 0.5
Probability of missing next shot if he misses = 1/6
a) Probability of scoring 2 shots later if he missed = (1-1/6)^2
=(5/6)^2
=25/36
b) % of successful shots= (1/2+5/6×(1/100))%
=4/3×1/100
=0.013%
A and B are complementary to each other. If m∠A = 26° + x and m∠B = 38° + x, what is the value of x?
A.13°
B.14°
C.58°
D.18°
Please don't reply just for the points, I really need help understanding these things, if possible please leave me an explanation on how you got this. P.S Complementary angles add up to 90 degrees
A. 13
Step-by-step explanation:
What we are given....
∠A = 26° + x
∠B = 38° + x
∠A and ∠B are complementary
If complementary angles add up to equal 90° and ∠A and ∠B are complementary to each other
Then 26 + x + 38 + x = 90
^ ( Note that we just created an equation that we can use to solve for x )
Now its just basic algebra
26 + x + 38 + x = 90
step 1 combine like terms
26 + 38 = 64
x + x = 2x
we now have 64 + 2x = 90
step 2 subtract 64 from each side
64 - 64 cancels out
90 - 64 = 26
we now have 26 = 2x
step 3 divide each side by 2
26 / 2 = 13
2x / 2 = x
we're left with x = 13

Lesley purchased 5 beads at a total cost of 80 cents. The round beads cost 15 cents each, and the oval beads cost 20 each. The equations and graph below can be used to determine the number of each type of bead kesley purchased. Where x represents the number of round beads and y represents the number of oval beads. What are the numbers of round and oval beads Kelsey purchased?
Answer:
Lesley purchased 1 oval bead and 4 round beands.
Step-by-step explanation:
Given that Lesley purchased 5 beads at a total cost of 80 cents, and the round beads cost 15 cents each, and the oval beads cost 20 each, to determine what are the numbers of round and oval beads Kelsey purchased, the following calculation must be performed :
5 x 0.20 + 0 x 0.15 = 1
4 x 0.20 + 1 x 0.15 = 0.95
2 x 0.20 + 3 x 0.15 = 0.85
1 x 0.20 + 4 x 0.15 = 0.80
Therefore, Lesley purchased 1 oval bead and 4 round beands.

Answer:
37.9 degrees
Step-by-step explanation:
Using the law of sines, [tex]\frac{\sin(m\angle C)}{21}=\frac{\sin(47^\text{o})}{25}[/tex]. It follows that [tex]\sin (m\angle C) = \frac{21\sin(47^\text{o})}{25} \approx 0.6143371[/tex]. Therefore, [tex]m\angle C = \sin^{-1}(0.6143371)=37.9^\text{o}[/tex].

A firefighter is on the fifth floor of an office building. She needs to throw a rope into the window on the seventh floor, 40 feet above her. If she throws the rope upward with an initial velocity of 36 ft/s, will the rope get to the window.
Answer:
no, it wont
Step-by-step explanation:
2g.h = v²
2(33)(40) = v²
2640=v²
v=√2640 = 51.38 ft/s
36 < 51.38
so, the rope will not get to the window
X= root (y-1/y+1) ( make “y” as subject. ) number 19
Answer:
y = (x² + 1) / (1 – x²)
Step-by-step explanation:
x = √[(y – 1)/(y + 1)]
We can make y the subject of the expression as shown below:
x = √[(y – 1)/(y + 1)]
Take the square of both side
x² = (y – 1) /(y + 1)
Cross multiply
x²(y + 1) = (y – 1)
Clear bracket
x²y + x² = y – 1
Rearrange
x² + 1 = y – x²y
Factorise
x² + 1 = y(1 – x²)
Divide both side by (1 – x²)
y = (x² + 1) / (1 – x²)

1/2×40×30600in²total area of arrow=a1+a2
600+6001200in²stay safe healthy and happy.Answer:
Step-by-step explanation:
You will find authentic some of the areas of 3 shapes, two of them are triangles, and one is rectangle.
The formula for calculating the area of right angle triangle is A= 1/2bh
The formula used to find the area of rectangle is A= W×L
A1+A2+A3
= 1/2b1h1+ 1/2b2h2+ W×L
1/2(10inches)(30inches)+ 1/2 (10 inches)(30 inches)+ (30 inches)(20 inches)
=150 inches²+ 150 inches²+ 600inches²
=900 inch²
