Step-by-step explanation:
Lavender has worked:
- from 3:13 to 4. That is 47 minutes, and
- from 4:00 to 4:37. An additional 37 minutes.
Total minutes: (47 + 37) = 84 minutes

Which fraction correctly represents one whole?
5/5
1/5
3/5
5/1
Answer:
5/5
Step-by-step explanation:
If you convert these fractions into decimals, you will get
5/5 = 1
1/5 = 0.2
3/5 = 0.6
5/1 = 5
Hope this helps :)
Answer:
5/5
Step-by-step explanation:
if you want to divide 1 whole into a fraction then the top number would have to be the same as the bottom number, for example 5/5. The top number is 5 which is the same as the numerator which will equal to 1 whole.
While 1/5 and 3/5 is less than 1 whole
And 5/1 is more than 1 whole but its way past the numerator
Mr. Martinez decided to invest his money in a mutual fund. This table gives the amount of money Mr. Martinez had in his account over the course of 42 months. The table can be modeled using an exponential function.
Months 6 12 18 24 30 36 42
Account value $1,339 $1,798 $2,408 $3,225 $4,321 $5,792 $7,766
What function best represents the data?
A) y=75 x 1. 22x
B) y=75x
C) y=1000+1. 34x
D) y=1000 x 1. 05x
Answer:
y=1000⋅1.05x
Step-by-step explanation:
I took the test.
The function that most effectively represents the given data would be:
D). y = 1000 × 1.05x
Exponential Function
Given that,
No. of the months Account value
6 $1,339
12 $1,798
18 $2,408
24 $3,225
30 $4,321
36 $5,792
42 $7,766
The function that represents the given data effectively:
y = 1000 × 1.05x
This helps in showing the times by which the value variates every 1000.
Thus, option D is the correct answer.

Answer:
1/6
Step-by-step explanation:
This is conditional probability.
If heads is tossed, then and only then does he have the option to draw either green or red and have the full 'Head, Green/Red' combination.
So, the probability of the first event - getting heads, is 1/2, since either heads or tails can be flipped with 50/50 chance.
The probability of the second event - picking either green or red, is 1/3, since there are 6 colour options - blue, red, yellow, green, orange and purple - of which 2 can be chosen. Thus, 2/6, which simplifies to 1/3
Now since these are both independent events, we must multiply their probabilities.
1/3 * 1/2 = 1/6

Answer: The number is 2
Step-by-step explanation: Suzie says that [tex]\frac{1}{2}[/tex], which is half of a whole, is equal to only [tex]\frac{1}{4}[/tex] of the unknown number. This means that to find the value of the unknown number, you need to multiply [tex]\frac{1}{2}[/tex] by 4 so that it equals to [tex]\frac{4}{4}[/tex] of the mystery number.
Simply put, multiply [tex]\frac{1}{2}[/tex] by 4. Then reduce for the answer, and this gives us these equations.

Look at each choice and use today's numbers.
A. roses: 18; daisies 9
18 is twice 9.
True
B. roses: 18; lilies: 12
18 and 12 are certainly not equal.
False
C. Lilies: 12, but roses 18
It's more roses than any other.
False
D. Lilies: 12; roses: 18
It's 6 more roses than lilies, not the other way around.

Find the product of (x + 5)(x - 5).
x2 - 10x + 25
x2 + 10x + 25
x2 - 25
x2 + 25
Answer:
x²-25
Step-by-step explanation:
Hi there!
We are given (x+5)(x-5) and we want to find their product.
As these are binomials, we can multiply them using FOIL, which is First, Outer, Inner, Last
So let's start with the firsts, which would be (x+5)(x-5), or the 2 x's; x*x=x²
Next, let's do the outers, which would be (x+5)(x-5); x * -5 = -5x
Now the inners; (x+5)(x-5); 5 * x = 5x
Finally, the lasts; (x+5)(x-5); 5 * -5 = -25
Now add all of these terms together:
x²-5x+5x-25
We can combine the 5x and -5x together to become x²-25
So the answer is x²-25, which is a difference of squares expression (if we have (a-b)(a+b), then the result is a²-b²).
Hope this helps! :)

a company can make a new computer for $150. if they sell the same computer for $500, what is the markup percentage?
Solution:
Note that:
Profit percentage: S.P - C.P/C.P x 100C.P = $150S.P = $500Substitute the values into the expression to find the profit percentage.
Substituting the values.
S.P - C.P/C.P x 100=> 500 - 150/150 x 100=> 350/150 x 100=> 350/3 x 2 = 233.33%The markup percentage is 233.33%.
Calculate an estimate of the median for each of the following.
Answer:
the median somewhere in the range of (120,160]
Step-by-step explanation:
the median is always the center of the data points.
There are 100 data points, so the median is the mean of the points 50&51.
Those points are found between 120 and 160 so the median is also found there.

Q2) A cylinder with a diameter of 4 ft, and height of 6 ft. Find the VOLUME and SURFACE are of the cylinder.
Answer:
Volume: 75.39 ft^3
Surface area: 100.5 ft^2
Step-by-step explanation:
To find volume, you use the formula V=πr^2h (V=3.14*2^2*6)
To find the surface area you use formula A=2πrh+2πr^2 (A=2*3.14*2*6+2*3.14*2^2)
Here are descriptions for how two dot patterns are growing,
• Pattern A Step 2 has 10 dots. It grows by 3 dots at each additional step.
Pattern B: The total number of dots can be expressed by 2n^2+1, where n is the
step number
For each pattern, draw a diagram of Step 0 to Step 3.
The steps in the patterns A and B form a sequence
The attached diagram represents dots in patterns A and B
How to draw the diagramsFor pattern A, we have:
Step 2 = 10 dots
Increment of 3 dots in each step
This means that:
Step 0 = 4 dots
Step 1 = 7 dots
Step 2 = 10 dots
Step 3 = 13 dots
For pattern A, we have the following rule
[tex]T_n =2n^2 + 1[/tex]
When n = 0 to 3, we have:
[tex]T_0 =2(0)^2 + 1 =1[/tex]
Step 0 = 1 dot
[tex]T_1 =2(1)^2 + 1 =3[/tex]
Step 1 = 3 dots
[tex]T_2 =2(2)^2 + 1 =9[/tex]
Step 2 = 9 dots
[tex]T_3 =2(3)^2 + 1 =19[/tex]
Step 3 = 19 dots
Next, we draw the diagrams of both patterns (see attachment)

write the equation in slope-intercept form. (-7,-2), (2,3)
Answer:
y = -5/9x + 4.1
(try doing this yourself first with different points to make sure this is the right answer, because im to lazy to check myself but ill try checking D:)
Step-by-step explanation:
first you have to find the slope . to do this use the equation y2 - y1/ x2 - x1
so write as -2 - 3/ -7 - 2 is equal to -5/-9
so now write y = -5/9x + b
we must now find the y-intercept so substitute one of the points given. lets substitute 2,3 it looks easier. So it will look like 3 = -5/9(2) + b
3 = -5/9(2) + b
3 = -10/9 + b
b = 3 + 10/9
b = 4.111111

Using it's concept, it is found that there is a 0.04 = 4% experimental probability of rolling a 5 on the red number cube, NCI, and a 2 on the blue number cube, NC2.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In an experimental probability, these number of outcomes is taken from previous trials.
Researching this problem on the internet, it is found that out of the 250 rolls, 10 resulted in a 5 on NC1 and 2 on NC2, hence:
p = 10/250 = 1/25 = 0.04.
