How do I divide 3 1/3 by 2/9
Answer:
15
Step-by-step explanation:
thats the answer im not sure if u want me to explain it. But if you do need it to be explained look it up. Give brainliest please.
Answer:
15
Step-by-step explanation:
Turn 3 1/3 to an Improper Fraction
to do that you have to multiply the Whole Number (3) by the Denominator(3)
3×3=9
Then add the numerator (1)
9+1=10
3 1/3 will turn into 10/3
then since you're divided you're going to have to KCF(Keep, Change, Flip)
2/9 will turn into 9/2
When you Flip, Divison will turn into Multiplcation

Your friend says that enough information is giving to prove that x=12. Is your friend correct?
Answer:
C. Yes, you can prove that x = 12
Step-by-step explanation:
My friend is correct because by the HL Congruence Theorem, ∆MNP is congruent to ∆MKL. The hypotenuse and leg of one right ∆ is congruent to the hypotenuse and corresponding leg of the other right ∆. So, enough information was given to prove that x = 12.
Peter wanted to leave a 15% tip. He thought to himself that 15% = 10% plus half of 10%. Which of the following equations will help Peter estimate the 15% tip on a $48.00 bill correctly?
A. $4.80 + $2.40 = $7.20
B. $4.80 + $4.80 = $9.60
C. $4.80 + $0.48 = $5.28
D. $2.40 + $2.40 = $4.80
Answer:
A. $4.80 + $2.40 = $7.20
Step-by-step explanation:
10% is the same as 10/100 or 1/10. To find 10% of a number, move the decimal point one place to the left.
10% of $48 is $4.80
Now he needs 5% of $48 which is half of 10% of $48, so 5% of $48 is $2.40.
$4.80 + $2.40 = $7.20
Answer: A. $4.80 + $2.40 = $7.20
Simplify the following expression.
13x+11y-3x+3y+9
Answer:
10x+14y+9Step-by-step explanation:
13x+11y-3x+3y+9
10x+11y+3y+9
10x+14y+913x + 11y - 3x + 3y + 9
This problem consists of combining alike parts of the equation. This means 13x and - 3x go together, 11y and 3y go together, and 9 has no other alike parts.
This shows that the answer (when combining like terms) is:
10x + 14y + 9
A certain insecticide kills 60% of all insects in laboratory experiments. A sample of 12 insects is exposed to the insecticide in a particular experiment. What is the probability that exactly 10 insects will die
Answer:
The probability that exactly 10 insects will die
P( X = 10 ) = 0.06385
Step-by-step explanation:
Step(i):-
Given a certain insecticide kills 60% of all insects in laboratory experiments
Given proportion p = 0.60
q = 1 - 0.60 = 0.40
Given sample size 'n' = 12
Step(ii):-
Let "X' be the random variable of binomial distribution
[tex]P(X=r) = n_{C_{r} } p^{r} q^{n-r}[/tex]
The probability that exactly 10 insects will die
[tex]P(X=10) = 12_{C_{10} } (0.60)^{10} (0.40)^{12-10}[/tex]
[tex]n_{C_{r} } = \frac{n!}{(n-r)!r!} = \frac{12!}{(12-10)!10!} = 66[/tex]
[tex]P(X=10) = 66 X (0.60)^{10} (0.40)^{2} = 0.06385[/tex]
Final answer:-
The probability that exactly 10 insects will die
P( X = 10 ) = 0.06385

josè and nancy take care of animals when the owners are away. josè charges $15 plus $2 per animal. nancy charges $5 plus $3 per animal. for how many animals do they charge the same amount?
get it right i will give you 100 points
Hey there! I'm happy to help!
Here's José's equation.
J=2a+15
And here is Nancy's.
N=3a+5
We want to find the number of animals where they are the same amount, or where J=N. We can write these equations as equal and solve for a to find the answer!
2a+15=3a+5
Subtract 15 from both sides.
2a=3a-10
Subtract 3a from both sides.
-a=-10
Divide both sides by -1.
a=10
Therefore, José and Nancy charge the same amount for 10 animals.
Have a wonderful day! :D
Geometry Special Quadrilaterals show work please
Answer:
a = 16
w = 125
x = 120
y = 55
Step-by-step explanation:
FINDING 'a'
31 = a + 46 / 2
62 = a + 46
16 = a
FINDING 'w'
* This section looks Non-Isosceles trapezoid so I will be following the rule according it
w + 55 = 180
w = 125
FINDING 'y'
y = 55
- Because of corresponding angles
FINDING 'x'
* In this case it looks like we are still dealing w/ an non-isosceles trapezoid.
x + 60 = 180
x = 120

find the mean of the following frequency distribution: score:1,2,3,4,5,6,7. frequently :. 5,9,12,17,14,10,6
Answer:
Mean = 4.1
Step-by-step explanation:
Let the scores be denoted by x
Given the following data;
Scores (x) = 1, 2, 3, 4, 5, 6, 7
Frequency, F = 5, 9, 12, 17, 14, 10, 6
Total number, n = sum of frequency
[tex] Total \; number, n = 5 + 9 + 12 + 17 + 14 + 10 + 6 [/tex]
Total number, n = 73
[tex] F(x) = (1*5) + (2*9) + (3*12) + (4*17) + (5*14) + (6*10) + (7*6) [/tex]
[tex] F(x) = 5 + 18 + 36 + 68 + 70 + 60 + 42 [/tex]
F(x) = 299
[tex] Mean = \frac {F(x)}{n} [/tex]
[tex] Mean = \frac {299}{73} [/tex]
Mean = 4.1
Therefore, the mean of this frequency distribution is 4.1.

URGENT if triangle FGH is congruent to triangle KJH, find FH
Answer:
FH =KH if triangle FJH and KJH is congruent
Step-by-step explanation:
If two triangles FJH and KJH as shown n figure is congruent if,
FJ = KJ,
FH =KH and
JH =JH common
Triangle is congruent by SSS theorem
Therefore FH =KH
Answer:
FH=39
Step-by-step explanation:
FGH~KJH
GH=x+8
FH=4x-25
JH=32
KH=52
(these are the measurements I have)
x+8 / 32 = 4x-25 / 52
(cross multiply)
52(x+8) = 32(4x-25)
52x+416 = 128x-800
(subtract the 52x from the 128x)
416 = 76x-800
(add the 800 to the 416)
1216 = 76x
(divide the 76 over the 1216)
x = 16
(now plug x into FH)
FH = 4x-25
FH = 4(16)-25
FH = 39

The dog has been dieting for 19 weeks.
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the given problem,
Starting weight of the dog = 89.5 pounds
Halfway weight of the dog = 80 pounds
Weight the dog loses per week = 0.5 pounds
Weight loss = (89.5 - 80) pounds
= 9.5 pounds
If the dog loses 0.5 pounds in 1 week,
Then the dog will lose 9.5 pounds in (9.5 × 2) weeks
⇒ The dog will lose 9.5 pounds in 19 weeks.
Hence, we can conclude that the dog has week dieting for 19 weeks and lost 9.5 pounds.
