Iva wanted to train for a race by raning 10km over 3 days during the week. the first day she ran 1.37 km more than she ran on the second day. on the third day, she ran 0.98 km more than the second day. how many km she run on the third day ?
Answer:
3.53 km
Step-by-step explanation:
Let third day be X:
Second day: X - 0.98
First day: X - 0.98 + 1.37 = X + 0.39
X + X - 0.98 + X + 0.39 = 10
3X = 10.59
X = 3.53 kn

Emanuel is planting trees along a new city sidewalk. He plants the same number of trees on each city block. After 3 blocks, he has planted 15 trees. After 5 blocks, he has planted 25 trees. At what rate is Emanuel planting trees?
Answer:
Every 1 Block he is planting 5 tree's.
Step-by-step explanation:
There are multiple ways you can do it but the easiest I prefer is just to divided The Tree's by the Blocks.
Ex: 6 Blocks is 30 trees, Divide 30 by 6 and you get 5 for every block.
Emanuel is planting trees at a rate of 5 trees per block. This is determined by dividing the total number of trees by the total number of blocks planted.
Explanation:Emanuel is planting trees at a consistent rate. To find this rate, we can set up a simple ratio.
He planted 15 trees in 3 blocks, which simplifies to 5 trees per block. This can be confirmed by looking at the second part of the problem. After 5 blocks, he had planted 25 trees. If we divide the total number of trees by the total number of blocks (25 trees / 5 blocks), we also get 5 trees per block.
Therefore, the rate at which Emanuel is planting trees is 5 trees per block.

Choose the constant that could be multiplied by each equation to create a system of equivalent equations with opposite terms.
2x + 3y = 1
5x + 2y = 8
The first equation can be multiplied by 5 and the second equation by 2.
The first equation can be multiplied by –5 and the second equation by –2.
The first equation can be multiplied by –5 and the second equation by 2.
Answer:
I think it's the third one. Because it will make both equation's x a opposite value (one is positive and one is negative).
Step-by-step explanation:
Because 2x+3y=1*5= 10x+15y=5 and then 5x+2y=8*-2 = -10x+4y=-16 both equations will cancel the Xs out and then you can solve for Y.

2) .A is (2, 12) and B is (8, 2). What is the midpoint AB?
(3, 5)
(5, 7)
(4, 6)
(6, 10)
We can't answer the first question, because we know nothing about the spinner (looks like some information is missing).
As for the second question, the coordinates of the midpoint are simply the average of the coordinates of the endpoint, so if we let [tex]M[/tex] be the midpoint of [tex]A[/tex] and [tex]B[/tex], we have
[tex]M=\left(\dfrac{A_x+B_x}{2},\dfrac{A_y+B_y}{2}\right)[/tex]
Plugging in the numbers, we have
[tex]M=\left(\dfrac{2+8}{2},\dfrac{12+2}{2}\right)=(5, 7)[/tex]

320 cubic inches
128 cubic inches
448 cubic inches
Step-by-step explanation:
Step 1:
Given,
Dimensions of the first rectangular prism = l * b * h = 16*5*4
[length is 16 as the total length is 20 and the width of the 2nd prism till the dotted line is 4]
Dimensions of the second rectangular prism = l * b * h = 4*4*8
We need to determine volume of the 2 prisms and the whole figure. The volume of rectangular prism can be obtained by multiplying the length breadth and the height.
Step 2:
Volume of the first prism = l * b * h = 16*5*4 = 320 cubic inches
Volume of the first prism = l * b * h = 4*4*8 = 128 cubic inches
The volume of the whole figure is the sum of the 2 rectangular prisms = 320 + 128 = 448 cubic inches

What is the area of the rectagle 12 ft 4 ft
12 times 4 equals 48ft
Type the correct answer in each box. Use numerals instead of words.
The domain of this function is {-12, -6, 3, 15}.
Complete the table based on the given domain.
At x = –6, y = 11
At x = 3, y = 5
At x = 15, y = –3
At x = –12, y = 15
Solution:
The function is [tex]y=-\frac{2}{3} x+7[/tex].
The domain of the function is {–12, –6, 3, 15}.
Substitute x = –6 in the function to find y.
[tex]$y=-\frac{2}{3} (-6)+7[/tex]
y = 4 + 7
y = 11
Substitute y = 5 in the function to find x.
[tex]$5=-\frac{2}{3} x+7[/tex]
Subtract 7 from both sides, we get
[tex]$-2=-\frac{2}{3} x[/tex]
Multiply by [tex]-\frac{3}{2}[/tex] on both sides, we get
x = 3
Substitute x = 15 in the function to find y.
[tex]$y=-\frac{2}{3} (15)+7[/tex]
y = –10 + 7
y = –3
Substitute y = 15 in the function to find x.
[tex]$15=-\frac{2}{3} x+7[/tex]
Subtract 7 from both sides, we get
[tex]$8=-\frac{2}{3} x[/tex]
Multiply by [tex]-\frac{3}{2}[/tex] on both sides, we get
x = –12
At x = –6, y = 11
At x = 3, y = 5
At x = 15, y = –3
At x = –12, y = 15
What is the probability that 13 people have different birthdays
Answer: Your answer for 13 people should be somewhere in the 20% range. Letting n=13 and we have about a 80.56% probability that no two out of the 13 share a birthday. As stated, the complement of this is the probability that at least two of the 13 share a birthday.
Step-by-step explanation:
The probability that 13 people have different birthdays is calculated by multiplying the individual probabilities for each person, considering each additional person has one less available day to have a unique birthday, resulting in an overall probability of approximately 83.3%.
Explanation:The question asks what the probability is that 13 people have different birthdays, assuming we can neglect the impact of leap years. To solve this, we consider that there are 365 days in a year for a birthday to occur. The first person can have their birthday on any day, so the probability is 365/365. For the second person to have a different birthday, there are 364 possible days left, so the probability is 364/365. This pattern continues down for all 13 people.
For the 1st person: 365/365For the 2nd person: 364/365For the 3rd person: 363/365And so on until the 13th person.To find the overall probability, we multiply these probabilities together:
Overall probability = (365/365) * (364/365) * (363/365) * ... * (353/365) = 0.833, or 83.3% when rounded to one decimal place.
This calculation is a practical application of probability theory, demonstrating how the likelihood of events changes as conditions evolve, such as when considering the probability of shared birthdays among a group of people.
