What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The area of the dark area = 3cm × 3cm = 9cm²
The area of the white area = (18cm×18cm)-(3cm×3cm) = 315cm²
Now, the probability that the dart will hit a spot in the shaded square will be,
Probability = 9 / 315 = 0.028
Hence, the probability that the dart will hit a spot in the shaded square is 0.028.

Denver, Colorado is called " The Mile High City" because of it's elevation is 5280 feet above sea level. Someone tells you that the elevation of Death Valley, California is- 282 feet.
Answer:
A. 5,562 feet higher
B. 0 feet
Step-by-step explanation:
A. Calculation for how many feet higher is denver than death valley
Numbers of feet=5,280 feet-(- 282 feet)
Numbers of feet=5,280 feet+282 feet
Numbers of feet=5,562 feet higher
Therefore the numbers of feet higher is denver than death valley will be 5,562 feet higher
B. Since ocean level tend to have 0 feet which means that in a situation where you were standing close to the ocean what the elevation would be is 0 feet.
A boat is on the same horizontal level as the foot of a cliff and the angle of depression of the boat 30 degree. If the boat is 120m away from the foot of the Cliff, find the height of the Cliff to 3 significant figures
Answer:
69.282 m
Step-by-step explanation:
We can use the trigonometry of right triangles to solve this, since we are in the presence of a right triangle with acute angle 30 degrees, opposite side unknown (the vertical height of the cliff), and adjacent side equal to 120 m.
we use the tangent function to solve for the unknown, as shown below:
tan(30) = x/120
x = 120 * tan(30) = 69.282 m

b. 131
c. 93
d. 90
Option c. 93°.
Alright, so in this one um the angle um so uh this angle right here, let's see right here, right which these two angles these angles are going to be equal because those are vertical angles. So these this angle is equal to um So angle P. S. T. Is equal to one half the sum of those two arcs added together, so 43 plus 1 31 So one half of Uh was that 1 74, So 1 74, divide by two 87. So this is 87 and then you take 18687 And you get 93.
What is the measure of ∠ RST?Triangle RST is isosceles means that two of its angles are equal. (1) The measure of angle T is 100 degrees --> since no other angle can be equal to 100 degrees (because in this case, the sum of the angles will be more than 180 degrees) than the other two angles, R and S, are equal: R=(180-100)/2=40.

Which is an equivalent equation solved for t?
O te fry
O tufa
O t= a(f - V)
O t = v(f – a)
Answer:
[tex]\dfrac{v-u}{a}[/tex]
Step-by-step explanation:
The given equation should be:
v = u +at ...(1)
Where
u is initial velocity, v is final velocity, a is acceleration and t is time
We need to solve the above equation for t.
Subtract u from both sides.
v-u= u +at -u
v-u=at
Dividing both sides by a.
[tex]\dfrac{v-u}{a}=\dfrac{at}{a}\\\\t=\dfrac{v-u}{a}[/tex]
So, the expression for t is equal to [tex]\dfrac{v-u}{a}[/tex].

Members of a softball team raised $1648.50 to go to a tournament. They rented a bus for $896.50 and budgeted $47 per player for meals. Write and solve an equation which can be used to determine xx, the number of players the team can bring to the tournament.
Answer:
The number of players the team can bring to the tournament is 16.
Step-by-step explanation:
With the information provided, the equation would express that the total cost to go to the tournament is equal to the price to rent a bus plus the result of multiplying the amount per player for meals for the number of players.
Total cost=896.50+47x, where:
x is the number of players
Now, as you know that the softball team raised $1,648.50 to go to a tournament, you can replace the total cost with this number and solve for x:
1,648.50=896.50+47x
1,648.50-896.50=47x
752=47x
x=752/47
x=16
According to this, the answer is that the number of players the team can bring to the tournament is 16.
Answer:
Equation: 47x + 896.5 = 1648.5
X= 16

Robert spent $45 buying songs and movies at an online store that charges 1.75 for each song and $2.50 for each movie he purchased a total of 20 songs and movies combined write a system of equations that represents this situation
Answer:
x= number of songs bought
y= number of movies bought
1.75*x + 2.5*y = 45
x + y = 20
Step-by-step explanation:
Giving the following information:
Robert spent $45 buying songs and movies at an online store that charges 1.75 for each song and $2.50 for each movie he purchased a total of 20 songs and movies combined.
We need to establish a system of equations that represents this situation.
x= number of songs bought
y= number of movies bought
1.75*x + 2.5*y = 45
x + y = 20
Now, we can determine the x and y:
x= 20 - y
Substitute x:
1.75*(20 - y) + 2.5y = 45
35 - 1.75y + 2.5y = 45
0.75y = 10
y= 13
x= 20 - 13
x= 7
Prove:
1.75*7 + 2.5*13 = 45
7 + 13 = 20
