Answer:
241/81 cm^2
Step-by-step explanation:
[tex]2\: lenghts = wide\\\\lenght=x\\\\2x=wide\\\\Perimeter = 2(wide+lenght)\\\\P=2(2x+x)\\\\P=2(3x)\\\\P=7\frac{1}{3}\\\\\frac{22}{3}=6x\\\\x=\frac{22}{3*6}\\\\x=\frac{11}{9}\\\\width = 2x=2(\frac{11}{9})=\frac{22}{9}[/tex]
[tex]Area = lenght\times width\\\\Area = \frac{11}{9}\times\frac{22}{9}\\\\A=\frac{11*22}{9*9}\\\\A=\frac{242}{81}cm^2[/tex]
Answer:
[tex]2\frac{80}{81}[/tex] cm²
Step-by-step explanation:
A = lw
P = 2(l + w)
~~~~~~~~~~~
l = 2w
2(2w + w) = [tex]7\frac{1}{3}[/tex]
2(3w) = [tex]\frac{22}{3}[/tex]
3w = [tex]\frac{11}{3}[/tex]
w = [tex]\frac{11}{9}[/tex]
l = [tex]\frac{22}{9}[/tex]
A = [tex]\frac{22}{9}[/tex] × [tex]\frac{11}{9}[/tex] = [tex]\frac{242}{81}[/tex] = [tex]2\frac{80}{81}[/tex] cm²

It costs Guido $0.20 per minute to forward voicemail messages as texts to his cell phone. He already spent $4 in forwarding messages this month. His mom has spent $2 forwarding messages. It costs her $0.40 per minute so she can call long distance. Guido’s mom said they have to spend the same amount. How many minutes can he talk?
Answer:
10 Minutes
Step-by-step explanation:
To talk the same amount of time he would have to spend $2. So $0.20 per minute would mean that for 5 minutes it is $1, so he can have 10 minutes
of the 8 friends sitting around the table at lunch, 6 brought their lunch from home. Which
grid represents the percent of the friends who brought their lunch from home?
You didn't provide any grid, but I can tell you how to turn fractions into percentages: just build the following proportion
[tex]6\div 8=x\div 100[/tex]
and solve for [tex]x[/tex]:
[tex]x=\dfrac{600}{8}=75[/tex]
So, 75% of the friends brought their lunch from home.
find the measure of the line segment TV
9514 1404 393
Answer:
18
Step-by-step explanation:
When chords cross, the product of the lengths of the pieces is the same for each chord:
EU·ES = ET·EV
8·9 = (12x)(6x)
72 = 72x^2
x^2 = 1 ⇒ x = 1
Then the length of interest is ...
TV = ET +EV = 12·1 +6·1
TV = 18

What is the least common denominator of 1/2,2/3 and 3/8 OA) 48 OB) 24 O C) 16 OD) 12 plz help me
Answer:
24
Step-by-step explanation:
The required least common denominator (LCD) of 1/2, 2/3, and 3/8 is 24.
What is the least common denominator?The least common denominator has a defined factor that is least common among the factors of the denominator is called the least common denominator.
Here,
Rewrite each fraction with the least common denominator (LCD) of 24 by multiplying both the numerator and denominator by the appropriate factor:
1/2 = (1/2) * (12/12) = 12/24
2/3 = (2/3) * (8/8) = 16/24
3/8 = (3/8) * (3/3) = 9/24
Check that the fractions have the same denominator:
12/24, 16/24, and 9/24
Therefore, the least common denominator (LCD) of 1/2, 2/3, and 3/8 is 24.

A 6-ounce can of Frozen orange juice costs $1.02. Give the unit price in cents per ounce
The unit price in cents per ounce will be 17 cents / ounce.
The cost of the 6 ounce frozen orange juice is given as:
Cost = $ 1.02
We know that:
$ 1 = 100 cents.
So, by using multiplication, we get that:
$ 1.02 = 1.02 × 100 cents
$ 1.02 = 102 cents.
Now, Number of ounces = 6 ounces
Unit price in cents per ounce = 102 cents / 6 ounce
Unit price in cents per ounce = 51 cents / 3 ounce
Unit price in cents per ounce = 17 cents / ounce
Therefore, the unit price in cents per ounce will be 17 cents / ounce.

Ant Colony B. We will use a function, a table, and a
graph to compare these two ant colonies.
Ant Colony A: The function a(x) = 210(1.12) represents
the number of ants in Ant Colony A, x days after an
experiment starts. There is also a table provided for Ant
Colony A on the whiteboard.
Ant Colony B: There is a graph on the whiteboard that
represents the number of ants in Ant Colony B during
the same time period.

With individual lines at its various windows, a post office finds that the standard deviation for normally distributed waiting times for customers on Friday afternoon is 7.2 minutes. To test this claim, the post office experiments with a single, main waiting line and finds that for a random sample of 25 customers, the waiting times for customers have a standard deviation of 3.5 minutes.With a significance level of 5 percent, test the claim that a single line causes lower variation among waiting times (shorter waiting times) for customers. Degrees of freedom test statistic pvalue accept or reject
Answer:
We reject H₀ we found that at 5% significance level the single file causes shorther waiting times
Step-by-step explanation:
We will develop a chi-square test since it is a standard deviation test.
Conditions for chi-square test
1.-Population follows a normal distribution
2.-We have a random sample
Therefore
Test Hypothesis
Null hypothesis H₀ σ = 7,2
Alternative hypothesis Hₐ σ < 7,2
So it is a one tailed-test to the left
Sample size n = 25
Then df = 25 - 1 df = 24
Significance level α = 5% α = 0,05
With df = 24 and α = 0,05 we find
Χ₀ = 36,415
Computing X(s)
X(s) = ( n - 1 ) * σ² / (7,2)²
X(s) = 24* (3,5)² / 51,84
X(s) = 294/51,84
X(s) = 5,67
Comparing Χ₀ and Χ(s)
X(s) < Χ₀
So X(s) is in the rejection region and we reject H₀

Answer:
[tex]\frac{3}{10}[/tex]
Step-by-step explanation:
The easiest way to get the answer is to convert the decimal form into its fraction form. All you have to do is to take note of the number of decimal places in order to raise the number into the power of ten. 0.3 has one decimal place, thus, you can use 10.
[tex]\frac{3}{10}[/tex]Since there's no common factor, there's no cancellation needed. So, the answer is [tex]\frac{3}{10}[/tex].
Let' check.
If you divide 3 by 10, you will get the answer 0.3.
3 ÷ 10 = 0.3 (It's correct)You can get equivalent fractions to this by multiplying or dividing the numerator by the same number.
Example: [tex]\frac{3}{10}[/tex] x [tex]\frac{2}{2}[/tex] = [tex]\frac{6}{20}[/tex]
You may also use the fraction [tex]\frac{6}{20}[/tex] for your answer as this is also equivalent to 0.3.
