Answer:
if the first term is 13, the second will be 13+x, the third 13+2x and so on, the tenth term will be 13+9x=40 9x = 27 x = 3 so the difference between the terms is 3 the sum of the first 10 terms is 13*10 + (x+2x+…+9x) = 130 + 45x = 130 + 45*3 = 130 + 135 = 265

Answer: 105 in^2
Step-by-step explanation: The area of the square is 25 because 5x5=25. The area of each triangle is 20, because to find a triangle it is BxH/2. so 5x8/2=20. Multiply this by four because there are four triangles and add the area of the square. So 20x4= 80. 80+25=105

Answer:
Answer below in step section
Step-by-step explanation:
First we see the duck pond is at point (7,5) on the graph.
One way to get from (0,0) to (7,5) is to go up 5 points from the orgin and then turn right and go 7 points to get to Duck Pond.
Let me know if you need different directions because there are multiple ways to get from the orgin to the duck pond point!

Barb pulled the plug in her bathtub and it started to drain. The amount of water in the bathtub as it drains is represented by the equation L = -5t - 8t + 120, where L represents the number of liters of water in the bathtub and t represents the amount of time, in minutes, since the plug was pulled. How many liters of water were in the bathtub when Barb pulled the plug? Show your reasoning. Determine, to the nearest tenth of a minute, the amount of time it takes for all the water in the bathtub to drain.
The bathtub had 120 L of water before Barb pulled the plug.
It will take about 9.23 minutes for the water to drain out.
Given equation: L = -5t - 8t + 120
Simplified: L = -13t + 120
Notice how it's written in slope-intercept form (y = mx+b)
The y-intercept (L) is 120. So the coordinates for L = (0 , 120)
The coordinates mean that before the water in the bathtub began draining out, it initially had 120 Liters of water.
Now that we know how many liters there were before, the new equation would look like this: L = -13t --> 120 = -13t
Solving the equation, we get that t = -9.23 minutes
Since time can't be negative, we'll just say that it will take 9.23 minutes to drain out all the water.

The total number of logs in the pile will be 255.
What is the sum of an arithmetic sequence?Let a₁ be the first term, L be the last term, n be the number of terms, and d be a common difference.
Then the sum of the arithmetic sequence will be
S = (n / 2)[a₁ + L]
S = (n/2) [2a + (n − 1) d]
A pile of logs has 24 logs in the bottom layer, 23 in the second layer, 22 in the third, and so on. The top layer contains 10 logs.
The common difference is negative 1.
Then the nth term of the arithmetic sequence is given as,
10 = 24 + (n - 1) x (-1)
n - 1 = 14
n = 15
Then the total number of logs in the pile will be
S = (15/2) [24 + 10]
S = 7.5 x 34
S = 255
The total number of logs in the pile will be 255.

Johnny runs a hot dog stand. On Wednesday morning, he had 32 dozen hot dogs at his stand. The graph shows the number of hot dogs (in dozens) that remained unsold at the end of each day of sales.
I saw you got it in the comment section of the post, but yes, he sold 30 dozen hot dogs on Wednesday.
By using the information of the graph, we conclude that he sold 2 dozen (24 hot dogs) on Wednesday.
How many hot dogs did Johnny sell on Wednesday?
The graph shows how many dozens of hot dogs Johnny had at the end of each day.
We know that he started with 32 dozens, and in the graph, we can see that at the end of Wednesday he had a total of 30 dozens.
Then the amount that he sold that day is:
32 dozens - 30 dozens = 2 dozens.
On Wednesday, he sells 2 dozen of hot dogs.

4(2m-8)>48
Determine whether each mathematical statement is true or false. The answer choices on the right may be used more than once.
some math probssssssss
Answer:
m = 8
Step-by-step explanation:
turn it into a square and then you can divide 48 by 6 and the answer is 8
Answer:
the answer for the first one is 8 because we need to divide the area which is 48 by 6 to get the answer which is 8 so we multiply 6 times 8 to check if it is 48 and yes sir it is.
In the second one you need to divide 42 by 6 not by 4 and when you do that you get 7 so we multiplied 6 times 7 to check if the area is 42 and yes it is sir again so the first one is 8 and the second one is 7

question 1. A card is pulled from a standard deck of cards. Find the probability of getting a 2 or King.
question 2. A 6-sided number cube is rolled. Find the Probability of NOT getting a 2 or 5.
Answer:
question 1) 8/52
question 2) 2/3
Step-by-step explanation:
question 1) there are 52 cards in a standard deck. Of those 52 cards there are 4 of each card (e.i 4 aces, 4 kings, 4 tens, etc.). So, 4 of 52 cards are 2s and 4 of 52 cards are Kings. 4 + 4 is 8, so the probability of getting a 2 or a King is 8/52.
question 2) There are 6 numbers on a 6-sided number cube-- 1, 2, 3, 4, 5, 6. The numbers 2 and 5 can be crossed out because we want to find the probability of NOT getting a 2 or 5. This leaves you with the numbers 1, 3, 4, and 6. That is 4 of 6 numbers. Therefore the probability of NOT getting a 2 or 5 is 4/6. We can simplify 4/6 to 2/3.

500 people are asked to name their favorite color. The results of this survey are shown in the pie chart below:
Each sector of the pie chart makes an angle at the center. For example, the yellow sector makes an 18-degree angle, since 18 degrees is 5% of 360 degrees.
If we consider only the people who named a rainbow color (red, orange, yellow, green, blue, or purple), what percentage of those people preferred red?
Answer:
40 degrees is (40/360)=0.111=11.1%
The color closest to 11.1% is Purple at 12%.
The total who prefer a rainbow color is:
13+4+5+15+16+12=65
Of this 65, 13 prefer red, so 13/65=0.20,
of the people who preferred a rainbow color,
20% preferred red.
Step-by-step explanation:
The percentage of those people who preferred red is 20%.
What is a percentage?
The percentage means the required value out of 100.
It is calculated by dividing the required value by the total value and multiplying it by 100.
The percentage change is also calculated using the same method.
In percentage change, we find the difference between the values given.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Considering only the people who named a rainbow color (red, orange, yellow, green, blue, or purple).
This means,
Total percentage.
= (13 + 4 + 5 + 15 + 16 + 12)
= 65%
Now,
The percentage of those people preferred red.
= 13%/65% x 100 %
= 13/65 x 100
= 20%
Thus,
The percentage of those people who preferred red is 20%.
