We have a triangle with base b = 5 (the distance between (3,-2) and (-2,-2)) and height h = 2 (the perpendicular distance from the base to the vertex (0,0)).
We can calculate the area of this triangle as:
\(A=\frac{1}{2}bh=\frac{1}{2}\cdot5\cdot2=5\)Answer: A = 5 units²

Danny Completed 40% of his homework assignment his assignment contain 30 math problems how many problems does Danny’s still need to complete
Answers
Answer:
Step-by-step explanation:
Well, he completed 12 questions, so he has 18 left.
To get the solution, we are looking for, we need to point out what we know:
We assume, that the number 30 is 100% - because it's the output value of the task.
We assume, that x is the value we are looking for.
If 30 is 100%, so we can write it down as 30=100%.
We know, that x is 40% of the output value, so we can write it down as x=40%.
Now we have two equations:
1) 30=100%
2) x=40%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
30/x=100%/40%
Now we just have to solve the equation.
30/x=100/40
(30/x)*x=(100/40)*x - we multiply both sides of the equation by x
30=2.5*x - we divide both sides of the equation by (2.5) to get x
30/2.5=x
12=x
x=12
now we have:
40% of 30=12
Then, you need to subtract 12 from 30 to figure out what is left.

Step-by-step explanation:
I took the test
Marta should have plotted the ordered pairs that were given and then, starting with the last point, moved up 3 and right 2 to find each next point.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
We know Equivalent ratios are those ratios when two or more fraction on simplification gave the same value.
So, the find the equivalent ratio to given ratio can be achieved by multiplying or dividing the same number to Numerator and Denominator of the fraction.
Thus, Marta should have plotted the ordered pairs that were given and then, starting with the last point, moved up 3 and right 2 to find each next point.

Idaho Jones regains consciousness and next to her are 4 blodegradable packing peanuts. 5 seconds later each peanut has split in half, and each half grows into a full-size peanut. This repeats in the next 5 seconds. She sees a door with a keypad. A sign next to it has a timer indicating 10 seconds have passed and says the code is the number of peanuts when the timer reaches 100. (After 10 secords there were 16 peanuts.) Idaho realizes she must escape before then or the peanuts could suffocate her. Show how she figures out the code to open the door, and write what the code is

Answers
Answer: let me explain!
Step-by-step explanation: So this might seem really confusing at first, but it’s actually suuuuuuper easy :P
So, if you think about it, every five seconds the amount of peanuts…well I don’t know how to explain it but let me show you this with numbers.
(4x2)x2x2x2 and so on. The number multiplies by two every five seconds from there. So figure out how many groups of five second there are in 100 seconds by dividing!
It’s 20!
So since 5 happens 20 times, and every time 5 happens, 2 happens, 2 also happens 20 times! (If that makes any sense)
So that answer would be 8x*twenty twos*
Which is…*drumroll please*
8,388,608
I even double checked!
And for the briefcase skeleton thing
She needs to try it 25 times because there are 5 books and each book can be switched with the other 4 times if the first one doesn’t work, therefore you need to multiply and the equation would be 5^2, or in other words, 25.
Don’t forget ur units!

A straight highway is 100 miles long, and each mile is marked by a milepost numbered from 0 to 100. A rest area is going to be built along the highway exactly 7 miles away from milepost 58. If m is the milepost number of the rest area, which of the following equations represents the possible locations for the rest area?
Answers
Answer:
Step-by-step explanation:
The milepost number of the rest area is 7 miles away from milepost 58, so it can be represented by the equation:
m = 58 + 7
This equation states that the milepost number of the rest area is equal to 58 plus 7, or 65. Therefore, the rest area can be located at milepost 65.

From the graph attached,
Black curve represents a function f(x) = 2ˣ
When this curve is reflected over the x-axis image of the function will be,
g(x) = -\(2^{x}\) [Red curve]
Similarly, curve represented by h(x) = \(2^{-x}\) is the blue curve [image of f(x) reflected over y-axis]
When this curve is reflected over the x-axis, image of the function will be,

The weatherman says that in the countryside it will be -3 degree Celsius tonight, but in the city it will be 2degree Celsius warmer. What temperature will it be in the city
Answers
The temperature in the city will be = -1 degrees Celsius.
We have weatherman who says that in the countryside it will be -3 degree Celsius tonight but in the city it will be 2 degree Celsius warmer.
We have to determine what temperature will it be in the city.
What is Temperature?Temperature is the measure of hotness or coldness expressed in terms of any of several arbitrary scales and indicating the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature). One of the scale used to measure is degrees Celsius.
According to question, we have -
Temperature at the countryside = -3 degrees Celsius
Assume the temperature at the city = x degrees Celsius
For the temperature to be warmer -
x = - 3 + 2 = -1
Hence, the temperature in the city will be = -1 degrees Celsius

From there, he drove in the same direction at a speed of 5 blocks per minute until he
got to the bank, which is 10 blocks away from the store. He stopped at the bank for 3
minutes. Then he drove home at a speed of 4 blocks every minute. Make a graph of

leaves his house, until he gets back home.

What is graph?Graph is a data structure which is used to represent relationships between objects or data points. It is composed of nodes and edges, where nodes are the objects and edges are the connections between the objects. Graphs are used to represent mathematical equations, networks, and data structures such as trees. They are also used to represent relationships between data points in large datasets. Graphs can be used to represent both directed and undirected relationships, and are commonly used in many fields including computer science, engineering, mathematics, and data science.
From the given information, we can create a graph that shows Andrew's distance from home as he drives to the store, to the bank, and back again. The x-axis will represent time (in minutes), and the y-axis will represent the number of blocks away from home.
At time zero, Andrew is at his home, so the graph will begin with a point at (0, 0). As he travels to the store, the graph will move up 5 blocks for every minute he drives. Therefore, after 2 minutes, he will be 10 blocks away from home, so the graph will be at (2, 10). After he stops at the store for 2 minutes, he will still be 10 blocks away from home, so the graph will stay at (2, 10).
When he leaves the store and drives to the bank, he will move 5 blocks each minute. After 5 minutes, he will be 25 blocks away from home, so the graph will be at (5, 25). After he stops at the bank for 3 minutes, he will still be 25 blocks away from home, so the graph will remain at (5, 25).
Finally, when he drives home, he will move 4 blocks for each minute he drives. After 5 more minutes, he will be back at his home, so the graph will be at (10, 0).
Therefore, the graph of Andrew's distance from home will look like this:
Time (x-axis) 0 1 2 3 4 5 6 7 8 9 10
Distance (y-axis) 0 5 10 10 15 20 20 24 28 32 0
