What is the probability that he will not win?
Write the answer as a percentage
3/5 is the probability that he will win, you must find a fraction which adds to make 100%.
2/5 would be the fraction for his probability to lose.
0.4 or 40%.

A rectangular piece of paper with length 35 cm and a width 18 cm has two semicircles cut out of it as shown below
Answer:
375.66 cm²
Step-by-step explanation:
The two semicircles add to a full circle.
For the circle, d = 18 cm.
r = d/2 = 9 cm.
A = LW - πr²
A = (35 cm)(18 cm) - 3.14(9 cm)²
A = 375.66 cm²
An engineer is designing a fountain that shoots out drops of water. The nozzle from which the water is launched is 3 meters above the ground. It shoots out a drop of water at a vertical velocity of 14 meters per second. Function h models the height in meters, h, of a drop of water t seconds after it is shot out from the nozzle. The function is defined by the equation h(t)=−5t2+14t+3. How many seconds until the drop of water hits the ground?
Answer:
After 3 seconds
Step-by-step explanation:
Given
[tex]h(t) = -5t^2 + 14t + 3[/tex]
Required
Time the drop will hit the ground
When the drop hits the ground,
[tex]h(t) = 0[/tex]
So, we have:
[tex]0 = -5t^2 + 14t + 3[/tex]
Rewrite as:
[tex]5t^2 - 14t - 3 = 0[/tex]
Expand
[tex]5t^2 + t - 15t - 3 = 0[/tex]
Factorize
[tex]t(5t + 1) -3(5t + 1) = 0[/tex]
Factor out 5t + 1
[tex](t -3)(5t + 1) = 0[/tex]
Split
[tex]t -3 = 0[/tex] or [tex]5t + 1 = 0[/tex]
Solve for t
[tex]t = 3[/tex] or [tex]5t = -1[/tex]
Time cannot be negative.
So:
[tex]t = 3[/tex]

You have 4 pounds of peanuts. You want to put it in the bags so that there is 2/3 pounds in each bag. How many bags can you fill ?
Answer:
6 bags
Step-by-step explanation:
This problem is essentially asking how many ([tex]\frac{2}{3}[/tex]) peanut bags can one fill with ([tex]4[/tex]) pounds of peanuts. This problem can be solved by divided ([tex]4[/tex]) by ([tex]\frac{2}{3}[/tex]). Set up the problem,

Answer:
x = 9
Step-by-step explanation:
The top shape's side values are 3 times larger than the side values of the bottom shape, so x + 15 = 3(8).
Solve for x and you get x = 9.
Answer:
x = 9
Step-by-step explanation:
9 / x = 3 -> x = 3
(x+15) / 3 = 8
x + 15 = 8*3
x+15 = 24
x = 24 - 15
x = 9
What is the radius of the circle with equation (x+1/5)^2+(y-2/5)^2=1/25
Answer:
r = [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + [tex]\frac{1}{5}[/tex] )² + (y - [tex]\frac{2}{5}[/tex] )² = [tex]\frac{1}{25}[/tex] ← is in standard form
with r² = [tex]\frac{1}{25}[/tex] , then
r = [tex]\sqrt{\frac{1}{25} }[/tex] = [tex]\frac{1}{5}[/tex]
The radius of the circle is, r = 1/5 units.
What is equation of circle?An equation of circle with center (h, k) and radius 'r' is,
(x - h)²+(y - k)² = r²
For given example,
the equation of the circle is, (x+1/5)^2+(y-2/5)^2=1/25
By comparing with standard equation of circle (x - h)²+(y - k)² = r²,
we have h = -1/5, k = 2/5 and r² = 1/25
We need to find the radius of the circle,
r² = 1/25
By taking square-root,
we have r = 1/5 units
Therefore, the radius of the circle is r = 1/5 units.

The dimensions of this screen are 10 inches by 10 inches. What is the screen size? Round your answers to the nearest whole number. Remember, the screen size is the same as the hypotenuse of the triangle whose legs are the width and height of the screen.
Answer:
14.14inches
Step-by-step explanation:
Given data
Length L= 10 inches
Width W= 10 inches
The size of the screen is described by the lenght of the diagonal
Applying the Pythagoras theorem we have
D^2= L^2+ W^2
D^2= 10^2+ 10^2
D^2= 100+100
D^2= 200
D= √200
D= 14.14 inches
Hence the size of the screen is 14.14inches

:)) please help me out!
Answer:
1,296 cm³Step-by-step explanation:
Now the formula to find the volume of a pyramid is [tex]V=\frac{lwh}{3}[/tex]
We know the length, width and height so let´s get started!
First let´s multiply to find the base. To do so, we will do length × width.
18 × 18 = 324
Now multiply by the height
324 × 12 = 3,888
After you multiply all length, width and height, we need to divide by three.
3,888 ÷ 3 = 1,296
Before we finish, we need to do the last two steps
First we need to add the measurement unit which is centimetres or cm.
We also need to add ³ since it is volume
1,296 cm³ is our final answer
