Answer:
x----------> the length of the room
y----------> the width of the room
we know that
x*y=120---------> equation 1
y=(5/6)x--------> equation 2
substitute 2 in 1
x*[(5/6)x]=120------> (5/6)x²=120-----> x²=120*6/5-----> x²=144
x=12 ft
y=(5/6)*12-----> y=10 ft
the answer is
the dimensions of Winnie's bedroom are
the length of the room is 12 ft
the width of the room is 10 ft

A square photo has a side length of 0.17 foot. The photo is enlarged by doubling the dimensions. Then it is enlarged again by tripling the new dimensions.
Calculate the side length of the enlarged picture
Answer:
Hence, final picture will have a side length of 1.02 foot
Step-by-step explanation:
Side length of square photo, s = 0.17
Original dimension = (0.17 by 0.17)
Enlarged photo = double the original dimension:
2 * (0.17 * 0.17)
(0.34 * 0.34)
Second enlargement = Tripling the new dimension:
3 * (0.34 * 0.34)
(1.02 * 1.02)
Hence, final enlarged dimension = (1.02 * 1.02)
Hence, final picture will have a side length of 1.02 foot

Slope of the line perpendicular to line (y = 3x) = -1/m = -1/3
Equation of the line through origin : y = mx
[tex]y = \frac{-1}{3}x[/tex]

280 bananas
Write down the ratio of the number of apples that Scott buys to the number of
bananas that he buys.
Give your ratio in its simplest form.
Answer:
1,260:280
or
1,260 to 280
or
1,260/280 Simplified → 4 1/2
Step-by-step explanation:
Since it asks for apples first put the amount first apples first to the amount of bananas second, since it asks for bananas second.

Step-by-step explanation:
Marco picked answer A for the following problem. Why is that not the correct answer? (NO LINKS)
Answer:
This is not correct because the organic rice line in Graph A is increasing more than the conventional rice line. This is why the x- and y-labels are important: organic rice in Graph A; you are able to get more pounds for the same amount of weight. If organic rice costs more, you should get less pounds of rice. Graph B shows this relationship because the conventional rice line is higher than the orangic rice line, which indicates that you can get more conventional rice than organic rice at the same price, which is what the question says.

Miyoko bought 3 packages of tape that each had 1 yard 2 feet of tape in them how many inches of tape did miyoko buy?
Answer: 180 inch
Step-by-step explanation:
Given
Miyoko bought 3 packages of tape
Each tape has 1 yard and 2 feet of tape
[tex]1\ \text{yard}=3\ \text{foot}[/tex]
[tex]1\ \text{ft}=12\ \text{inch}[/tex]
converting yard to feet
[tex]\Rightarrow 3+2=5\ ft[/tex]
Convert feet to the inch
[tex]\Rightarrow 5\times 12=60\ \text{inch}[/tex]
For 3 tapes, it is
[tex]\Rightarrow 60\times 3=180\ \text{inch}[/tex]
Thus, the total tape is [tex]180\ \text{inch}[/tex]
The sodium content of a popular sports drink is listed as 220 mg in a 32-oz bottle. Analysis of 10 bottles indicates a sample mean of 228.2 mg with a sample standard deviation of 18.2 mg. (a) State the hypotheses for a two-tailed test of the claimed sodium content. a. H0: μ ≥ 220 vs. H1: μ < 220 b. H0: μ ≤ 220 vs. H1: μ > 220 c. H0: μ = 220 vs. H1: μ ≠ 220 a b c (b) Calculate the t test statistic to test the manufacturer’s claim. (Round your answer to 4 decimal places.) Test statistic (c) At the 5 percent level of significance (α = .05), does the sample contradict the manufacturer’s claim? H0. The sample the manufacturer’s claim. (d-1) Use Excel to find the p-value and compare it to the level of significance. (Round your answer to 4 decimal places.) The p-value is . It is than the significance level of 0.05. (d-2) Did you come to the same conclusion as you did in part (c)? Yes No
Answer:
Follows are the responses to this question:
Step-by-step explanation:
[tex]H_O: \mu=220\\\\H_a:\mu \neq 220\\\\[/tex]
0.05 degree of significance for two tail tests and n-1= 9 df, critica t= 2.262
When the absolute value of the test statistic |t| >2.262, the decision rule rejects[tex]H_0[/tex].
[tex]\mu=220\\\bar{x}=228.200\\n=10.00\\smaple \ std \ deviation = 18.200\\std\ error \ ' sx= \frac{s}{\sqrt{n}} =5.7553\\test stat t=\frac{(x-\mu) \times \sqrt{n}}{sx}=1.4248\\p value=0.1880\\[/tex]
In point c:
It does not reject[tex]H_0[/tex], because it has the sample that not contradicts the manufacturer's claim
In point d:
For point 1:
The value of p is 0.1880 , that is higher than the 0.05
For point 2:
Yes

Which of the following cannot be solved using nPr?
permutations of the letters of the word "OF"
permutations of the letters of the word "PERMUTATION"
permutations of the letters of the word "THINGS"
permutations of the letters of the word "N"
Answer:
permutations of the letters of the word "PERMUTATION"
Step-by-step explanation:
The number of permutations of the letters of the word "PERMUTATION" cannot be solved using nPr. The correct answer is B.
What is the permutation?The permutation is defined as considered an ordered combination.
The following formula computes the permutation of r items from n:
P(n, r) = n! /(n-r)!
here order matters and repetition is not allowed.
Therefore, nPr cannot be used to solve problems that involve repeating items or where order does not matter.
As per the question, the permutations of the letters of the word "OF", "THINGS", and "N" involve distinct letters and no repetition, so they can be solved using nPr.
However, the word "PERMUTATION" has repeated letters.
Therefore, the number of permutations of the letters of the word "PERMUTATION" cannot be solved using nPr because it does not account for repeated items.
