CAN SOMONE PLEASE HELP.
a coin is weighed so the probability of landing head is 0.6. If this coin is flipped teice find the experimatal probabillaty of getting two heads.Anwser as a percent
hi <3
simply multiply the probabilities together:
0.6 x 0.6 = 0.36
multiply by 100 to turn this into a percentage:
0.36 x 100 = 36
thus, your answer is 36%

6139m=_____km. answer pls i beg
Answer:
6.139km
Step-by-step explanation:
1000m = 1km
6139m = 6139/1000km = 6.139km
Answer:
6.139 km
Step-by-step explanation:
1 m = (1/1000) m
So, 6139 m
= (6139/1000) km
= 6.139 km
Solve for x and find the value of the unknown angle measures.
Answer:
x = 20
m = 92
n = 68
p = 92
Step-by-step explanation:
x = 20
2 + 3x = 62
-2 -2
----------------
3x = 60
----- -----
3 2
x = 20
m = 92
20 + 68 = 88
180 - 88 = 92
n = 68
The vertical angle is 68 degrees
p = 92
Vertical angle is m, which is 92.

6x - 6 = 54
Step-by-step explanation:
The hypotenuse of both triangles are 63 and 6x - 6; the second longest sides are 49 (greater than 35) and 42 (greater than 30).
So our proportion:
63/(6x-6) = 49/42
Cross multiply
63*42 = 49*(6x-6)
2646 = 294x-294
2940 = 294x
x = 10
Double-check:
63/(6*10 - 6) = 49/42
63/(60 - 6) = 49/42
63/54 = 49/42
7/6 = 7/6
6x - 6 = 6(10) - 6 = 60 - 6 = 54
simplify [(x-4)/(x-4)2]

If 2 + 2 could = 22, how can you make 2 + 2 = 5?
Answer:Of the ones mentioned here, I'd say that 3, redefine addition, is the easiest way to use and work with to get lots of self consistent theories that have 2 + 2 = 5.
Step-by-step explanation:
First, it’s easy to prove that 2 + 2 =4. You just need the rule x + Sy = S(x + y) where Sx means the successor of x, or x + 1. With some more steps, with simple natural axioms, you can also derive a contradiction from 2 + 2 = 5. Proof indented so it’s easy to skip.

You have 2 five-dollar bills, 4 one-dollar bills, 2 quarters, I nickel, and 2 pennies. a. What is the value of the bills? b. What is the value of the coins? c. How much money do you have?
Answer:
a: [tex]\$ 14[/tex] or [tex]14[/tex] dollars
b: [tex]\$0.57[/tex] or [tex]57[/tex] cents
c: [tex]\$14.57[/tex] or [tex]14[/tex] dollars and [tex]57[/tex] cents
Step-by-step explanation:
a: We have [tex]2[/tex] [tex]\$5[/tex] bills, which have a total value of [tex]2*5= \$10[/tex]. We also have [tex]4[/tex] [tex]\$1[/tex] bills, which have a total value of [tex]4*1= \$4[/tex]. Adding these up gives us [tex]10+4= \bf \$14[/tex] or [tex]\bf 14[/tex] dollars for the total value of the bills.
b: Remember that a quarter is worth [tex]\$0.25[/tex], a nickel is worth [tex]\$0.05[/tex], and a penny is worth [tex]\$0.01[/tex]. Therefore, [tex]2[/tex] quarters are worth [tex]2*0.25=\$0.50[/tex], [tex]1[/tex] nickel is worth [tex]1*0.05=\$0.05[/tex], and [tex]2[/tex] pennies are worth [tex]2*0.01=\$0.02[/tex]. Adding these up gives us [tex]0.50+0.05+0.02=\bf \$0.57[/tex] or [tex]\bf 57[/tex] cents for the total value of the coins.
c: We know that the total value of the bills is [tex]\$ 14[/tex] (or [tex]14[/tex] dollars) from Part A and the total value of the coins is [tex]\$0.57[/tex] (or [tex]57[/tex] cents) from Part B. Therefore, we have [tex]14+0.57=\bf \$ 14.57[/tex] in total or [tex]\bf 14[/tex] dollars and [tex]\bf 57[/tex] cents.

Answer:
Umm, I believe your only correct answer for your equation above would be -1.
Step-by-step explanation:
Using the PEDMAS method:
-2 - 3= -5
= -5 - (-4)
-(-4) = 4
= -5 + 4
-5 + 4 = -1
So, your answer would be -1. Hope this helps!

Answer:
Ada is correct.
Step-by-step explanation:
Problems with Naman:
Naman is supposed to follow PEMDAS, which is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Division
Addition
Subtraction
~
The mistake: Naman moved +6 to the left and added it to the 2 located on the left side of the expression. You cannot do that, as it breaks the law of PEMDAS. On the other hand, Ada did the correct thing, which was to distribute 2 to all terms within the parenthesis (as one term in the parenthesis has a variable, and the other is a constant, meaning that they cannot be combined). This leads to Naman not doing the rest of the question correct.
Next, Ada correctly combined the two constants, which resulted in 0. 0 means nothing, therefore the placeholder is not needed. Therefore, 8x is the final answer.

5 less than the difference of a number f and 35
Answer:
See below.
Step-by-step explanation:
There are 2 options in finding the difference between f and 35, as you did not state in the question which if the 2 is the larger number.
(f-35)-5=f-35-5
=f-40
OR
(35-f)-5=35-f-5
=30-f
5 less than the difference of a number f and 35 is f - 40
The expression can be represented mathematically as follows:
The difference of a number f and 35 can be represented as follows:

(a+b+c)^2 - a^2+b^2..................
Answer:
[tex]2b^2 + c^2 + 2ab + 2ac + 2bc[/tex]
Step-by-step explanation:
Whenever you have a parentheses to a power of a number you have to make it the parentheses times itself, so (a+b+c)^2 becomes (a+b+c)(a+b+c), where you then multiply a by a, a by b, a by c, b by a, b by b, b by c, and so on and then add all those numbers up. If you do that you would get a^2 + ab + ac + ab + b^2 + bc + ac + bc + c^2, where you then add them up to get a^2 + b^2 + c^2 + 2ab + 2ac + 2bc. Since you have - a^2 after this, you cancel out the a^2, and finally, you have + b^2 so you add b^2 to it and you get a final answer of 2b^2 + c^2 + 2ab + 2ac + 2bc.
Triangle ABC is similar to triangle PQR, as shown below:
Two similar triangles ABC and PQR are shown. Triangle ABC has sides AB equals c, BC equals a, and AC equals b. Triangle PQR has sides PQ equals r, QR equals p, and PR equals q. Angle CAB is congruent to angle RPQ. Angle ABC is congruent to angle RQP. Angle ACB is congruent to angle QRP.
Which equation is correct?
q over c is equal to r over b
c over p is equal to b over a
c over a is equal to q over r
q over b is equal to r over c
Answer:
q/b = r/c
Step-by-step explanation:
We can determine which equation is correct by looking at the similar angles
A ~ P and B ~ Q so the side length that is between these angles would be proportional which are :
r/c
Next up
C ~ R and again B ~ Q and the side length that is between these angles:
q/b
so the answer is
q/b = r/c as given in last option
