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.

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
Answers
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%
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.
Answers
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

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 )

Two supplementary angles differ by 34. Find the angles.
Answers
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°

John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs to maintain a ratio of pumpkin to green beans of 5 to 2. If he wants to use a total of 126 cans, how many cans of green beans should he use?
please help me lol
Answers
Answer:
90 pumpkin and 36 green beans
Step-by-step explanation:
Because there is a total of 7 parts (5+2) and I divided 126 by 7 and then put five of the 18ns (the quotient of 126 and 7) for pumpkins (so... multiply 18 by 5) then the other to times 18 is 36. And if you add them together, they equal 126.
Answer:
9 cans
Step-by-step explanation:
126/7=18
18/2=9
so 9 is the answer

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]
