Answer:
1/4 = 25%
Step-by-step explanation:
The probability of heads is 1/2.
The probability of an even number on a die is 3/6 = 1/2.
The probability of both is (1/2) (1/2) = 1/4, or 25%.
Answer:
make me brainlist pls pls pls pls
Step-by-step explanation:
A "fair" coin lands heads-up half of the time and "tails-up" half of the time.
For one flip, the probability of landing heads-up is 1/2.
Of those successes, we now consider the probability of the "fair" die landing with an even number on top. This probability is (number of successes) / (total number of possibilities) = 3/6, or 1/2.
So, the probability of both events happening ("and") is 1/2 of 1/2, or (1/2)*(1/2) = 1/4.
Find the point that lies on the line described by the equation below. y - 8 = - 3 (x-6)
Answer:
B. (6, 8)
Step-by-step explanation:
To figure this out, you can plug in the coordinates to see if you get matching answers. Since you believe answer "B," is correct, we can check:
y - 8 = -3(x - 6)
8 - 8 = -3(6 - 6)
0 = -3(0)
0 = 0
Since the answers match, that makes answer "B," correct.

Ariel is filling a giant beach ball with air. The radius of the beach ball is 30cm. What is the volume of air that the beach ball will hold? Either enter an exact answer in terms of π πpi or use 3.14Pi.
Answer:
V =36000 pi cm^3
Step-by-step explanation:
The volume of a sphere is
V = 4/3 pi r^3
We know the radius is 30
V = 4/3 pi (30)^3
V = 4/3 pi (27000)
V =36000 pi cm^3
please help ..its soo much to comprehend
Answer:
3600
Step-by-step explanation:so it is easiest to do one persons costs then just multiply it by 4 to get the cost of 4 people. so first for one person..... (their travel is) 130 + (hotel x 7 days) 60 x 7 + (spending money) 350 =900 . now multiply this by 4 = 3600
Let's start off by working out the cost for one person. This person has to spend 130 pounds on travel and have 350 pounds of spending money. So far that is 130+350 = 480 pounds. Then it says the hotel costs 60 pounds per day. At 7 days, it will cost one person 7*60 = 420 pounds. This adds onto the 480 to get 420+480 = 900.
Therefore, each person will need 900 pounds to go on a 7 day trip. If we had 4 people going, then 4*900 = 3600 pounds is needed total.

This strip is 12 cm long Find the length of 25% of the strip
Answer:
If the strip is 12cm and it is asking for 25% of it, you can divide 12 by 4, as 25 is 1/4 of 100.
The answer will be 3cm
Answer:
3
Step-by-step explanation:
Twenty five percent of the 12 cm strip means 25÷ 100 = 0.25 .
so 0.25 x 12 = 3.
Check that x=2 and y=5 is a solution of both equations below:
X+2y=12
3x+6y=36 *
Answer:
yes
Step-by-step explanation:
Substitute x = 2 and y = 5 into the left side of the equations and if equal to the right side then they are a solution.
x + 2y = 2 + 2(5) = 2 + 10 = 12 ← True
3x + 6y = 3(2) + 6(5) = 6 + 30 = 36 ← True
Thus x = 2, y = 5 is a solution to both equations

Answer:
A=238.87 cm
Step-by-step explanation:
First find the area for the rectangle
11*23= 253 cm
then find the area for the little circles
D=3cm so r=1.5cm
Now plug in values into formula
A=π(1.5)^2
A=π(2.25)
A=3.14(2.25)=7.065cm
A=7.065cm since there are two circles
7.065*2=14.13
Now subtract the area of the circles from the rectangle
253-14.13=238.87
The spinner to the right is spun 20 times. It lands on red 6 times, yellow 2 times, green 8 times, and blue 4 times.
Based on the data, what is the experimental probability of landing on yellow?
You may give your answer as a simplified fraction, decimal, or percent.
Answer:
0.1
Step-by-step explanation:
Given: The spinner lands on red 6 times, yellow 2 times, green 8 times, and blue 4 times. when it is spun 20 times.
To find: experimental probability of landing on yellow
Solution:
Probability refers to chances of occurring of some event.
Probability = number of favourable outcomes total number of outcomes
As the spinner lands on yellow 2 times,
number of favourable outcomes = 2
Total number of outcomes = 20
Probability = 2/20 = 1/10 =0.1

El caño de una fuente está inclinado 60° sobre la horizontal. Si el agua sale del caño con una velocidad inicial de 10 m/s: a) ¿Qué dibujo forma el chorro de agua? B) ¿Qué altura máxima alcanza el agua? C) ¿A qué distancia del caño hay que colocar el sumidero? D) ¿Cuál es el módulo de la velocidad del agua cuando esta cae al sumidero
Answer:
A) Parabola; B) 3.83 m; C) 8.84 m; D) 10 m/s
Step-by-step explanation:
A) Shape of water jet
The water jet has the shape of a parabola.
B) Maximum height
Data:
θ = 60°
u = 10 m/s
a = 9.8 m·s⁻²
Calculations:
1. Calculate the horizontal and vertical components of the velocity
[tex]u_{\text{h}} = u \cos \theta = \text{10 m/s} \times \cos 60 ^{\circ} = \text{10 m/s} \times 0.5 = \text{5 m/s}\\u_{\text{v}} = u \sin \theta = \text{10 m/s} \times \sin 60 ^{\circ} = \text{10 m/s} \times 0.866 = \text{8.66 m/s}[/tex]
2. Maximum height
[tex]H = \dfrac{(u_{\text{v}})^{2}}{2a} = \dfrac{8.66^{2}}{2\times 9.8} =\textbf{3.83 m}[/tex]
C) Range
1. Calculate the time of flight
Use the vertical component of velocity to calculate the time to the maximum height of the stream.
[tex]u_{\text{v}} = at\\t = \dfrac{ u_{\text{v}}}{a} = \dfrac{\text{8.66 m$\cdot$s}^{-1}}{\text{9.8 m$\cdot$s}^{-2}}= \text{0.884 s}[/tex]
It will take the same time to reach the ground.
Thus,
Time of flight = 2t = 2 × 0.884 s = 1.77 s
2. Calculate the horizontal distance
s = vt = 5 m·s⁻¹ × 1.77 s = 8.84 m
You should place the drain 8.84 m from the pipe.}
D) Modulus of velocity
The stream of water will hit the drain with the same velocity as when it left the pipe.
Thus, the modulus of the velocity is 10 m/s.
The graph below shows the trajectory of the water stream.

Answer:65miles
Step-by-step explanation:
Let the needed miles be x
(67+62+59+47+x)/5=60
235+x=60×5
235+x=300
x=300-235
x=65miles
A rectangular building has a perimeter of 208 meters. It’s area is 2415 square meters. What are the dimensions of the building?
Answer:
Step-by-step explanation:
Perimeter of rectangle = 208 m
2*(l + w) = 208 {divide both sides by 2}
l +w = 208/2
l +w = 104
l = 104 - w
Area of rectangle = 2415 square meters
l*w = 2415
Substitute l = 104 - w in the above equation,
(104 - w ) *w = 2415
104w - w² = 2415
0 = 2415 - 104w + w²
w² - 104w + 2415 = 0
Sum = -104
Product = 2415
Factors = (-69) , (-35)
w² - 35w - 69w + (-69)*(-35) = 0
w(w - 35) - 69(w - 35) = 0
(w -35)(w -69)
w - 35 = 0 ; w -69 = 0
w = 35 ; w = 69
The dimensions of the building: 35 , 69
