In 2011, 39 people died by being struck by lighting, and 24 people were injured. There were l 310,000,000 people in the United States. What is the probability of being one of the people struck by lighting
Answer: 0.0000203%
Step-by-step explanation:
The total number of people struck by lightning includes both those who died and those who were injured:
= 39 + 24
= 63 people
Probability of being struck is:
= People struck / U.S. Population
= 63 / 310,000,000
= 0.0000203%
Noah was doing some homework and answer the following question 5.5• - 3/5 =
Answer:
-33/10 or -3.3
Step-by-step explanation:
Two supplementary angles differ by 34. Find the angles.
Answer:
x=107,y=73 is ur answer
Step-by-step explanation:
let two angles be x & y
x-y=34(given)
x=34+y................1
x+y=180(supplementary)
putting the value of x
34+y+y=180
2y=180-34
y=146/2=73
:.y=73
putting the value of y in equation 1
x=34+73=107
:.x=107
Answer:
73° and 107°
Step-by-step explanation:
Mark one of the angles as x
then the other angle is (x + 34)
Two angles are called supplementary when their measures add up to 180 degrees.
So the sum of those angles is always 180°
x + (x + 34) = 180
2x + 34 = 180
2x = 180 - 34
2x = 146
// divide both sides by 2
x = 73°
Now find the other angle
x + 34 = 73 + 34 = 107°
Why are equivalent equations important when solving a system using linear combination?
Answer:
Linear equations are an important tool in science and many everyday applications. They allow scientist to describe relationships between two variables in the physical world, make predictions, calculate rates, and make conversions, among other things. Graphing linear equations helps make trends visible.

Step-by-step explanation:
In a lab, 700 cells are present at the beginning of an experiment. During the first 7 hours,
the number of cells increased by 12% each hour.
Estimate the time when the number of cells is 1735.
Round answer to nearest whole hour.
Answer:
2 hours
Step-by-step explanation:
1=700
x=1735
1735=700x
1735/700
x=2.47
Answer:
Step-by-step explanation:
This is an exponential equation of the form, A=ar^t, where a is the initial amount and r is the common ratio or rate of growth and t is time. In this case.
A=700(1.12)^t and we want to find when A=1735
1735=700(1.12)^t
1735/700=1.12^t
ln(1735/700)=t(ln(1.12))
t=(ln(1735/700))/(ln(1.12))
t=8 hours

A group of students go to the store to buy school supplies. If they buy three
binders and four notebooks, the bill will be $4.85. If they buy three binders and
ten notebooks, the bill will be $8.75. What is the cost of each binder and
notebook?
Answer: Binder = 75c notebook = 65c
Step-by-step explanation:
3b + 10n = 875
3b + 4n = 485
Subtracting gives:
6n = 390
390/6 = 65
n = 65
Substitute 65 into 3b + 4n = 485
3b + 260 = 485
3b = 485 - 260
3b = 260
b = 75

Answer:
8 plus 8 then 4 plus 4 then add those, so your answer would be 24 cm
Two pools are being filled with water. To start, the first pool contains 1900 liters of water and the second pool contains 1529 liters of water. Water is being added to the first pool at a rate of 21.5 liters per minute. Water is being added to the second pool at a rate of 34.75 liters per minute.
After how many minutes will the two pools have the same amount of water?
How much water will be in each pool when they have the same amount?
Answer:
after 36 minutes the two pools will have the same amount of water.
2110 liters of water would be in each pool when they have the same amount.

PLS HELP I REALLY NEED IT
Answer:
A.)
Step-by-step explanation:
5.7^2+3.2^2=42.73
Sqrt of 42.73=6.5
Given :
Length of leg in a triangle = 3.2 cm
Length of leg of another triangle = 5.7 cm
We know that :
[tex]\color{hotpink}\tt {hypotenuse}^{2} \color{plum} = {base}^{2} + {height}^{2} [/tex]
Which means :
[tex] = \tt {3.2}^{2} + {5.7}^{2} = {h}^{2} [/tex]
[tex] =\tt 42.73 = {h}^{2} [/tex]
[tex] =\tt \sqrt{42.73} = h[/tex]
[tex]\hookrightarrow\color{plum} \tt6.5 \: cm= hypotenuse[/tex]
Thus, the hypotenuse of this triangle = 6.5 cm
Therefore, the correct option is (A) 6.5 cm

Solve x^2 + 2x - 48 = 0
Answer:
x = - 8, x = 6
Step-by-step explanation:
[tex] {x}^{2} + 2x - 48 = 0 \\ \\ {x}^{2} + 8x - 6x - 48 = 0 \\ \\ x(x + 8) - 6(x + 8) = 0 \\ \\ (x + 8)(x - 6) = 0 \\ \\ x + 8 = 0 \: \: or \: \: x - 6 = 0 \\ \\ x = - 8, \: \: \: \: x = 6 \\ [/tex]
I need help with these questions. Please show workings.
Answer:
see explanation
Step-by-step explanation:
∠ AOB = 360° - 264° = 96°
The altitude OM bisects ∠ AOB and the base AB
(a)
∠ MOB = 0.5 × 96° = 48°
Using the cosine ratio in right triangle MOB
cos48° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{OM}{OB}[/tex] = [tex]\frac{18}{r}[/tex] ( OB is the radius r of the circle )
Multiply both sides by r
r × cos48° = 18 ( divide both sides by cos48° )
r = [tex]\frac{18}{cos48}[/tex] ≈ 27 cm ( to the nearest cm )
(b)
Using the tangent ratio in the right triangle MOB
tan48° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{MB}{OM}[/tex] = [tex]\frac{MB}{18}[/tex] ( multiply both sides by 18 )
18 × tan48° = MB then
AB = 2 × MB = 2 × 18 × tan48° = 36 × tan48° ≈ 40 cm ( to nearest cm )

help 8+x2=−12..im confused
Answer:
Step-by-step explanation:
No real solutions exist. Subtract 8 on both sides to get:
[tex]x^2=-20[/tex]
You cannot take the square root of a negative number without involving imaginary numbers.
Answer and Explanation
__________________________________________________________
-10__________________________________________________________
The answer is -10 because...
You need to multiply 2 by "x," and to find out what "x" is, we need to add...
[tex]2+-12[/tex]
__________________________________________________________
And if we add [tex]2[/tex] by [tex]-12[/tex], we get [tex]-10[/tex], which is our answer.
__________________________________________________________
and now, if we add [tex]-20[/tex] by [tex]8[/tex], we get [tex]-12[/tex], which is what the equation equals, and this is how we know it is correct.
