Solve these with proportions. Set them up like this:
[tex]\frac{part}{whole} =\frac{percentage}{100}[/tex]
Say I have a question that said "Arjun had Rs. 10, and his friend Raghav borrowed Rs. 5, what percentage of Arjun's amount did Raghav borrow?". 10 is the whole. It is the total amount of money that they have. 5 is the part. You are looking for the percentage. The 100 will always stay the same. Put the values that you know into the proportions, and replace what you don't know with the variable x. Like so:
[tex]\frac{5}{10} = \frac{x}{100}[/tex]
To solve this, use cross multiplication. Multiply the top left with the bottom right, and the bottom left with the top right. You will get:
5(100) = 10x
Simplify.
500 = 10x
Now, to solve this, you must isolate the x. To do this, divide both sides by 10, to get:
50 = x.
50 is your percentage.
You can solve this kind of problem by just remembering the proportion, filling in what you know, and then solving!
#8 and #9
To solve these types of problems, set up an equation.
Say that I had the question "Sowmya is baking cupcakes. She has 10 cups of flour, and she uses 2 cups for each cupcake. How many cupcakes can she bake?
What do you know?
You know she has 10 cups in total. You know that she uses 2 cups per cupcake.
So, you will set up the equation like this:
2x = 10
Where x is the number of cupcakes she makes.
To solve, you will isolate the variable by dividing both sides by 2 to get:
x = 5.
Sowmya can bake 5 cupcakes with 10 cups of flour.
Hope this helps!
On average, Nancy has noticed that 18 trucks pass by her apartment daily (24 hours). In order to find the probability that more than 4 trucks will pass her apartment in a 5-hour time period using the Poisson distribution, find the average number of trucks per 5 hours. Round your answer to three decimal places, if necessary.
Answer:
the average number of trucks per 5 hours is 3.750 trucks per 5 hours
Step-by-step explanation:
The computation of the average number of trucks per 5 hours is given below:
= Number of trucks passed ÷ time taken × given time
= 18 trucks ÷ 24 trucks × 5
= 3.750 trucks per 5 hours
Hence, the average number of trucks per 5 hours is 3.750 trucks per 5 hours
The same is to be considered by applying the above formula

Answer:
[tex] \sec( \frac{x}{3} ) + 4 > 2 - \sec( \frac{x}{3} ) \\ 2 \sec( \frac{x}{3} ) > - 2 \\ \sec( \frac{x}{3} ) > - 1 \\ \boxed{y = \sec( \frac{x}{3} )} \\ \boxed{y = - 1}[/tex]
B) is the right answer.
Answer:
B
Step-by-step explanation:
We want to solve the inequality:
[tex]\displaystyle \sec\Big(\frac{x}{3}\Big)+4>2-\sec\Big(\frac{x}{3}\Big )[/tex]
First, we can add sec(x/3) to both sides:
[tex]\displaystyle2 \sec\Big(\frac{x}{3}\Big)+4>2[/tex]
Subtracting 4 from both sides yields:
[tex]\displaystyle 2\sec\Big(\frac{x}{3}\Big)>-2[/tex]
And dividing both sides by 2 yields:
[tex]\displaystyle \sec\Big(\frac{x}{3}\Big)>-1[/tex]
Therefore, we can graph the following two functions:
[tex]\displaystyle y=\sec\Big(\frac{x}{3}\Big)\text{ and } y=-1[/tex]
Where our solutions will be all the intervals where y = sec(x/3) is above the line y = -1.

The number of DVDs sold at a store in a month was 925 and the number of DVDs sold decreased by 12 per month. The number of Blu-ray discs sold in the same store in the same month was 507 and the number of Blu-ray discs sold increased by 26 per month. Let d represent the number of discs sold and t represent the time in months.
Write a system of equations by filling in the blanks:
d= _ t+ _
d= _ t+ _
Solve the system of equations using the substitution method. Complete the sentence to describe the solution.
There will be _ DVDs and Blu-Ray discs sold per month in _ months
Answer:
See belowStep-by-step explanation:
DVDs
d = 925 - 12tBlu-rays
d = 507 + 26tSolve the system:
925 - 12t = 507 + 26t26t + 12t = 925 - 50738t = 418t = 418/38t = 11Number of disks sold in 11 months:
925 - 12*38 = 469There will be 469 DVDs and Blu-Ray discs sold per month in 11 months

Jake got 12 questions correct on a 20 question test. What percent did Jake get correct
Answer:
2.4?
I'm not completely sure but I think that may be the correct answer.
(Edit) Oh it's not. It's 60%. Well ok.
(Edit 2) Thank you for letting me try-.
Answer:
60%
Step-by-step explanation:
We can set this up as the proportion is/of=%/100. So,
12 = %
20 100
First, multiply across with 12x100. 12x100=1,200.
Now, divide 1,200 by 20. 1,200/20=60
Jake got 60% on the test.
Hope this helps!! Have a nice day .,.

Is (x-2) a factor of f(x) = (4x +13x +10)?
Answer:
Step-by-step explanation:
No but it is close. (4x +13x +10) factors into
(4x + 5)(x + 2)
So (x + 2) is a factor along with (4x + 5)

Which answer describes the transformation of g(x) = log2 (x+3) + 1 from the
parent function f(x) = log2 x ?
A. It is the graph of f(x) shifted 3 units left and 1 unit up.
B. It is the graph of f(2) shifted 1 unit right and 3 units down.
C. It is the graph of f(2) shifted 3 units right and 1 unit down.
D. It is the graph of f(2) shifted 3 units right and 1 unit up.
Answer: C
Step-by-step explanation:
Answer:
It is the graph of f(x) shifted 3 units left and 1 unit up.
Step-by-step explanation:
Any number inside the parentheses that is either negative or positive will do the exact opposite as stated in the equation, it is shifting 3 units to the left. We can also assume that it shifts 1 unit up since it is + 1.
Lena has three cups of milk in a refrigerator she needs 1/3 of a cup of milk to make a BATCHES of 6 cupcakes how many cupcakes will need to be able to make with that amount of milk in the refrigerator
Answer: Lena will be able to make 54 cupcakes.
Step-by-step explanation:
If 1/3 cups has t make 6 cups , then we can set up a proportional relationship and find out how much 3 cups of milk can make.
[tex]\frac{1/3}{3} = \frac{6}{x}[/tex] Cross multiply
1/3x = 18 Multiply both sides by 3.
x = 54
Help me out with this question (geometry)
Answer:
I believe the answer is 32 degrees. The reason I believe this is because the line VP splits the whole angle and at the right end of the line, closest to letter P both sides make the new two triangles right angles. This leads me to believe that the line VP splits the triangle equally into two parts which means both angle 2 and angle 1 would have to add up to 64 degrees.
