7 divided by 9=28 divided by y
Answer:
7/9=28/y
We move all terms to the left:
7/9-(28/y)=0
Domain of the equation: y)!=0
y!=0/1
y!=0
y∈R
We add all the numbers together, and all the variables
-(+28/y)+7/9=0
We get rid of parentheses
-28/y+7/9=0
We calculate fractions
The required answer is y = 36 is the value that makes the equation true.
Given that 7 divided by 9=28 divided by y
A proportion is an equation that relates two ratios or fractions, stating that they are equal. It can be used to solve problems involving ratios or to find an unknown value.
To solve a proportion, we use the concept of cross-multiplication. This involves multiplying the numerator of one fraction by the denominator of the other fraction and setting the two products equal to each other.
To find the value of y in the equation 7 divided by 9 = 28 divided by y, set up a proportion and solve for y.
The proportion can be written as:
7 / 9 = 28 / y
To solve for y, by cross-multiplication:
7 x y = 9 x 28
Simplifying:
7y = 252
Dividing both sides of the equation by 7:
y = 252 / 7
y = 36
Therefore, the value of y that satisfies the equation 7 divided by 9 = 28 divided by y is y = 36.
Substitute y = 36 into the equation, gives:
7 / 9 = 28 / 36
After simplifying both sides of the equation, we find that both fractions are equal to 4/9.
Hence, y = 36 is the value that makes the equation true.

Complete Question
Mariah and Clarence are planning for a dinner party. The grocery store is selling a 25- pound turkey for $60 . Mariah states, "that means it costs $2.40 per pound of turkey." Clarence states, "that means $2.4 pounds of turkey cost $1 Is Mariah's statement, Clarence's statement, both statements, or neither statement correct?
Answer:
Mariah's statement is correct
Step-by-step explanation:
Mariah and Clarence are planning for a dinner party. The grocery store is selling a 25- pound turkey for $60 .
From the statements given above, we are to find the unit rate . This means the cost of the turkey per pound
Hence, the calculation is given below:
25 pounds of turkey = $60
1 pound of turkey = x
Cross Multiply
25 × x = $60 × 1
x = $60/25
x = $2.40
1 pound of turkey cost $2.40
Therefore, Mariah's statement is correct

C 64.32 × 10^5
D 64.32 × 10^6
E (9.6 × 6.7) × (10^3 × 10^2)
The expression (9.6 × 10³) × (6.7 × 10²) can be simplified in scientific notation as 6.432 × 10⁶ , 64.32 × 10⁵ and (9.6 × 6.7) × (10³ × 10²) .
Scientific notation is a means to express values that are either too big or too little to be conveniently stated in decimal form (typically would result in a long string of digits). It is also known as standard form in the UK and scientific form, standard index form, and standard form. Scientists, mathematicians, and engineers frequently utilize this base ten notation because it can make some mathematical operations simpler.
The given expression is : (9.6 × 10³) × (6.7 × 10²)
First we multiply the decimal terms separately.
So (9.6 × 6.7) = 64.32 and now we multiply the power terms
10³ × 10² = 10²⁺³ = 10⁵ ( By using the properties of exponents)
So in proper scientific notation 64.32 × 10⁵ = 6.432 × 10⁶
Which can also be written as 6.432 × 10⁶ or (9.6 × 6.7) × (10³ × 10²) .

A popular resort hotel has 300 rooms and is usually fully booked about 7% of the time a reservation is cancelled before the 6:00 pm deadline with no penalty. What is the probability that at least 285 rooms will be occipied? Use the binomial distribution to find the exact value and the normal approximation to the binomial and compare your answers.
Answer:
Binomial distribution = 0.1026
Normal approximation = 0.1066
Step-by-step explanation:
Given that :
p = 100% - 7% = 0.93
n = 300
1 - p = 0.07
Probability of atleast 285 rooms getting booked :
P(x = x) = nCx * p^x * (1-p)^(n-x)
To obtain P(x ≥ 285) ; we use a binomial probability calculator to save time :
P(x ≥ 285) = 0.1026
Using Normal approximation :
Mean (m) = np = 300 * 0.93 = 279
Standard deviation (s) = sqrt(np(1-p) = sqrt(285*0.07) = 4.419 = 4.42
Using :
Z = (x - m) / s
P(x ≥ 285) ; for normal approximation :P(x ≥ x) x = 285 - 0. 5 = 284.5
Z = (284.5 - 279) / 4.42
= 1.2443
P(Z ≥ 1.2443) = 0.1066 (Z probability calculator)

The sum of two numbers is 92. One eighth of the larger number plus one third of the smaller number is 19. Find the numbers.
Answer:
The numbers 'x' and 'y' are:
[tex]x=56,\:y=36[/tex]
Step-by-step explanation:
Let 'x' and 'y' be the two numbers
As the sum of the two numbers is 92.
so
[tex]x+y = 92[/tex]
Given that One-eighth of the larger number plus one-third of the smaller number is 19.
so
[tex]\frac{1}{8}x\:+\:\frac{1}{3}y=19[/tex]
now solving both equations to determine the numbers 'x' and 'y'.
[tex]\begin{bmatrix}\frac{1}{8}x+\frac{1}{3}y=19\\ x+y=92\end{bmatrix}[/tex]
[tex]\mathrm{Multiply\:}\frac{1}{8}x+\frac{1}{3}y=19\mathrm{\:by\:}8\:\mathrm{:}\:\quad \:x+\frac{8}{3}y=152[/tex]
[tex]\begin{bmatrix}x+\frac{8}{3}y=152\\ x+y=92\end{bmatrix}[/tex]
[tex]x+y=92[/tex]
[tex]-[/tex]
[tex]\underline{x+\frac{8}{3}y=152}[/tex]
[tex]-\frac{5}{3}y=-60[/tex]
[tex]\begin{bmatrix}x+\frac{8}{3}y=152\\ -\frac{5}{3}y=-60\end{bmatrix}[/tex]
solve for y
[tex]-\frac{5}{3}y=-60[/tex]
[tex]-5y=-180[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}-5[/tex]
[tex]\frac{-5y}{-5}=\frac{-180}{-5}[/tex]
[tex]y=36[/tex]
[tex]\mathrm{For\:}x+\frac{8}{3}y=152\mathrm{\:plug\:in\:}y=36[/tex]
[tex]x+\frac{8}{3}\cdot \:36=152[/tex]
[tex]x=56[/tex]
Thus, the numbers 'x' and 'y' are:

Identify the graphed linear equation?
Answer:
C
Step-by-step explanation:
The first thing I notice is the slope, which is going down, which means this is for sure a negative slope. So any slopes that just include 5 is now crossed off. And since the formula goes like y=mx+b, I believe the answer would be C, because it actually follows the formula as it should. If I'm wrong, pick D for sure.

A clothing store is having a sale. Last week, a coat originally priced at $110 and was discounted by 45%. This week, the coat was discounted by 30% of last weeks sale price. What is the price of the coat after the second discount is applied
Answer:
The price of the coat after the second discount is applied is $42.35.
Step-by-step explanation:
First, you need to find the amount after the first discount by multiplying the original price by 45% and subtracting that amount from the initial price:
$110*45%=$49.5
$110-$49.5=$60.5
Now, you have to find the price of the coat after the second discount by calculating 30% of the price after the first discount and subtracting the result from that price:
$60.5*30%=$18.15
$60.5-$18.15=$42.35
According to this, the answer is that the price of the coat after the second discount is applied is $42.35.
