The amount of rainfall during one week is shown in the graph below. The rainfall is measured in centimeters and the time is measured in days. Each interval from 0 to 1 on the x-axis represents the 24-hour period for day 1, the interval from 1 to 2 represents the 24-hour period for day 2, etc. Choose the correct statement from the choices below.
Answers
Answer: C: It did not rain on 3 days; it did rain on 4 days
The solution to the equation of graph is it did not rain on 3 days ; it did rain on 3 days
What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the equation of graph be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The graph is rising on 0 to 1 , 2 to 4 and 5 to 6
The graph is a straight line from 1 to 2 , 4 to 5 and 6 to 7
So , the graph is rising represents the rain was there for 3 days
And , when the graph is a straight line , the rainfall was absent
Hence , the graph represents it did not rain on 3 days ; it did rain on 3 days

Answer:
The solution to the system of equations is:
[tex]x=10,\:y=4[/tex]
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}5x-4y=34\\ -x+8y=22\end{bmatrix}[/tex]
Multiply -x+8y=22 by 5: -5x+40y=110
[tex]\begin{bmatrix}5x-4y=34\\ -5x+40y=110\end{bmatrix}[/tex]
so adding the equations
[tex]-5x+40y=110[/tex]
[tex]+[/tex]
[tex]\underline{5x-4y=34}[/tex]
[tex]36y=144[/tex]
solve 36y = 144 for y:
[tex]36y=144[/tex]
divide both sides by 36
[tex]\frac{36y}{36}=\frac{144}{36}[/tex]

Two trains, Train A and Train B, weigh a total of 381 tons. Train A is heavier than Train B.
The difference of their weights is 193 tons. What is the weight of each train?
I need this answer quick!
Answers
Answer:
Train A is 287 tons
Train B is 94 tons
Step-by-step explanation:
My method of solving it may have been a bit different from how you were taught. I divided 381 by 2 to give both trains an equal weight of 190.5 tons. I then divided the difference, 193, by 2 to get 96.5 tons. I subtracted the new difference from the weight of Train B and added it to train A. To double check, you can grab a calculator and see that their weights are equal to 381.

Olivia has a points card for a movie theater. She receives 80 rewards points just for signing up. She earns 2.5 points for each visit to the movie theater. She needs at least 105 points for a free movie ticket. Write and solve an inequality which can be used to determine xx, the number of visits Olivia can make to earn her first free movie ticket.
Answers
Answer:
10 visits
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Rewards for signing up = 80 points
Reward per visit = 2.5 points
Total points needed = 105
Let, number of visits = x
So, we can calculate number of visits by using following formula,
80 + (2.5 × X) = 105
2.5X = 105 - 80
2.5X = 25
X = 25 ÷ 2.5
X = 10 visits.
Hence, Olivia needs to make 10 visits in order to earn a free movie ticket.

1.How do you know you have a direct variation in the
relationship between two quantities?
Answers
Answer:
Say you have y=2x. That is direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2x to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.

You have 5 choices of shirts: red, blue, green, yellow, brown; 3 choices of pants: green, brown, black; 4 choices of
socks: black, brown, tan, white; and 3 choices of shoes: white, brown, black. What is the probability that you will
dress all in brown-shirt, pants, socks, and shoes?
Answers
Answer:
15% chance
Step-by-step explanation:
The required probability is 0.0166 that you will dress all in a brown shirt, pants, socks, and shoes.
How to find probability?The probability that you will dress all in brown is the product of the probability of selecting each brown item.
There is only one choice of brown shirt out of a total of 5 shirt choices, so the probability of selecting a brown shirt is 1/5.
Similarly, there is only one choice of brown pants out of a total of 3 pant choices, so the probability of selecting brown pants is 1/3.
There is also only one choice of brown socks out of a total of 4 sock choices, so the probability of selecting brown socks is 1/4.
Finally, there is also only one choice of brown shoes out of a total of 3 shoe choices, so the probability of selecting brown shoes is 1/3.
To find the overall probability of dressing all in brown, you need to multiply these probabilities together: (1/5) × (1/3) × (1/4) × (1/3) = 1/60.
This means the probability of dressing all in brown is approximately 0.0166, or about 1.7%.

If we define the line QR to be some variable of distance 'x', we can use the relationship of cosine to figure out the length of QR.
Remember, cosine is adjacent of the angle divided by the hypotenuse of the angle. So, if we take this x value over the longest side (hypotenuse), we get the value of cos(theta).
cos(25) = x/7

make sure
he doesn't run out of coffee.
How many days can be use the 340-gram bag of coffee beans before he buys a new bag?
Answers
Answer:
Jesse should buy a new bag in 16 days.
Step-by-step explanation:
He uses 18.75 grams a day.
We can multiply the amount of grams by the amount of days.
18.75 x 16 = 300
He stops using the bag when he uses 300 grams.
So he uses 1 bag for 16 days
1 bag can last for 16 days.

Given that, in ΔKLM, l = 820 cm, m = 560 cm and ∠K=169°, we need to find the length of side k,
Using the cosine law,
k² = l²+m² - lmCos169°
