The sum of 5/2 and 6 times a number equals to 7/2 subtracted from seven times the number find the number
Answers
Answer:
1 / 13
Step-by-step explanation:
lets just say the number is 'x'
5/2 + 6x = 7/2 - 7x
6x + 7x = 7/2 - 5/2
13x = 2/2
13x = 1
x = 1/13
proving it
5/2 + 6 × 1/13 = 7/2 - 7 × 1/13
5/2 + 6/13 = 7/2 - 7/13, solving the fraction by finding the L.C.M will result in

Answer:
C
Step-by-step explanation:
4 boxes: $3.79 is $0.9475 or $0.95
a. 6 boxes: $5.79 is $0.95833333333 or $0.96
b. 2 boxes: $1.96 is 0.98
c. 3 boxes: $2.79 is $0.93
d. 1 box: $0.97 os $0.97
0.98 > 0.97 > 0.96 > 0.95 > 0.93
Answer:
3rd answer choice: 3 for $2.79
Step-by-step explanation:
“You bought 4 boxes of facial tissues for $3.79.Which is a better buy than the one you bought?”
First, find the individual box cost for the given amount in the question. Divide the total cost ($3.79) with the amount of boxes (4) to get the individual amount:
$3.79/4 = ~0.9475, or $0.95
The first answer choice looks like 6 boxes for $5.75. Divide 6 from $5.75:
$5.75/6 = ~0.9583, or $0.96 (1 cent more)
The second answer choice looks like 2 boxes for $1.96. Divide 2 from $1.96:
$1.96/2 = 0.98, or $0.98 (3 cent more)
The third answer choice looks like 3 boxes for $2.79. Divide 3 from $2.79:
$2.79/3 = 0.93, or $0.93 (2 cents less).
The fourth answer choice looks like 1 for $0.97.
$0.97 (2 cents more)
~
In this case, the cheapest one by individual costs is the 3rd answer choice, as it is the cheapest by individual boxes.

3) A grocery store has cereal on sale. If the original price is $4.50 and the sale
price is $3, what percent is the discount?
Answers
Step-by-step explanation:
original price = $4.50
sale price = $3
discount price = $4.50 - $3
= $1.50
discount = discount percent × original price ÷ 100
$1.50 = discount percent × $4.50 ÷ 100
discount percent = $1.50 × 100 ÷ $4.50
= 33.33%

Answers
Answer:
8(a+2c)
Step-by-step explanation:
Hey There!
If you didn't know the greatest common factor (GFC) is the largest number that all of the numbers can be divided by and have a whole number as the outcome
For this expression the GFC is 8 because both of the terms can be divided by 8 and have a whole number as a result
8a/8=a
16c/8=2c
So the factored version of 8a+16c is 8(a+2c)

x is opposite the 90 degree angle. It is the hypotenuse. 15 is opposite the 66 degree angle. It is the side opposite.The side opposite and the hypotenuse define the sin(theta).Formula
sin(theta) = side opposite / hypotenuse
Givens
Theta = 66 degrees
Hypotenuse = x
Side Opposite = 15
Solution
Sin(theta) = 15 / x Multiply both sides by xx*sin(theta) = 15 Divide by Sin(theta)x = 15/sin(theta)x = 15 / sin(66)sin(66) = 0.9135x = 15/ 0.9135x = 16.42Need help ASAP please

When a certain basketball player takes his first shot in a game he succeeds with prob. 1/3. If he misses his first shot, he loses confidence and his second shot will go with prob. 1/4. If he misses his first 2 shots, his third shot will go with pro. 1/5. If he misses his first 3 shots, his fourth shot will go with prob. 1/6. If he misses his first 4 shots, the coach will remove hom from the game. Assume that the player keeps shooting until he succeeds or he is removed from the game. Let X denote the number of shots he misses until his first success or until he is removed from the game.
Required:
a. Compute the p.m.f. of X.
b. Compute E[X]
Answers
Solution :
Let the number of the shots that the player while playing misses until the first success = x
The random variable X can take the values {0, 1, 2, 3, 4}
[tex]$P(x=0)$[/tex] = probability of the player that does not misses the 1st shot
The probability of the player that he success at the 1st shot = [tex]$\frac{1}{3}$[/tex]
[tex]$P(x=1)$[/tex] = probability of the player that misses the 1st shot but succeeds in his 2nd shot [tex]$=\frac{2}{3} \times \frac{1}{4}$[/tex]
[tex]$=\frac{1}{6}$[/tex]
[tex]$P(x=2)$[/tex] = probability of the player that misses the 1st two shot but succeeds in the 3rd shot [tex]$=\frac{2}{3} \times \frac{3}{4}\times \frac{1}{5}$[/tex]
[tex]$=\frac{1}{10}$[/tex]
[tex]$P(x=3)$[/tex] = probability of the player that misses the 1st three shot but succeeds in the 4th shot [tex]$=\frac{2}{3} \times \frac{3}{4}\times \frac{4}{5} \times \frac{1}{6}$[/tex]
[tex]$=\frac{1}{15}$[/tex]
Similarly,
[tex]$P(x)$[/tex] = (probability of missing the 1st four shots) x (probability of removing te player after the 1st four shots missed)
[tex]$=\frac{2}{3} \times \frac{3}{4}\times \frac{4}{5} \times \frac{5}{6} \times 1$[/tex]
[tex]$=\frac{1}{3}$[/tex]
a). The p.m.f of the X
X = x 0 1 2 3 4
P(X=x) [tex]$\frac{1}{3}$[/tex] [tex]$\frac{1}{6}$[/tex] [tex]$\frac{1}{10}$[/tex] [tex]$\frac{1}{15}$[/tex] [tex]$\frac{1}{3}$[/tex]
b). [tex]$E(X) = \sum x \times P(X=x)$[/tex]
[tex]$= 0\times \frac{1}{3}+1\times \frac{1}{16}+2\times \frac{1}{10}+3\times \frac{1}{15}+4\times \frac{1}{3}$[/tex]
[tex]$=\frac{114}{60}$[/tex]

The atomic mass of a chemical element is the number of protons + number of neutrons in each atom of that element—electrons are ignored. Examples The atomic mass of hydrogen (H) is 1 (1 proton) and that of helium (He) is 4 (2 protons + 2 neutrons).
The gram atomic mass of a chemical element is the atomic mass of that element in grams. Example The gram atomic mass of H is 1 gram and that for He is 4 grams.
Astounding Fact There are approximately 6 x 1023 atoms in the gram atomic mass of every known chemical element. Examples There are 6 x 1023 atoms in 1 gram of H and in 4 grams of He. Hence, there are 12 x 1023 atoms, or 1.2 x 1024 atoms, in 2 grams of H and in 8 grams of He.
Standard carbon is Carbon 12, abbreviated C-12. Its atomic number is 12 (6 protons and 6 neutrons) and its gram atomic mass is therefore 12 grams.
How many atoms are there in 96 grams of C-12? (Read the exponents carefully.)
(a) 1.2 x 1024 atoms (b) 12 x 1023 atoms (c) 4.8 x 1023 atoms
(d) 4.8 x 1024 atoms (e) 96 x 1024 atoms (f) none of the above

Answers
Answer:
86.4 seconds.
Step-by-step explanation:
Given that Jack and Jill are 432 meters apart, but are walking towards each other, and Joe walks at a pace of 2 meters per second, while Jill walks at a pace of 3 meters per second, to determine after how many seconds will they meet up, the following calculation must be performed:
432 / (3 + 2) = X
432/5 = X
86.4 = X
So, Jack and Jill will meet after 86.4 seconds.
