If It's CORRECT I will give BRAINLIEST!!!!!
Answer:
Im pretty sure its C... Step-by-step explanation: what im seeing here is 10 with the small numbers in front so it looks like scientific notation, Maria has 1 million because 1 x a number = that number, 10 multiplied by itself 6 times equals 1 million, 10 x10 = 100 x 10 = 1000 x 10 = 10,000 x 10 = 100,000 x 10 = 1,000,000. so from this we know what Larry's 10 to the power of 5 is, we need to know what 100,000 x whatever equals. If im doing this right, Larry's number is 1 million 2 hundred thousand which is greater than 1 million. (sorry if the explanation is wanky and sorry if it was wrong, im new to brainly.)

Answer:
A) solution 2 is more acidic than solution 1
Step-by-step explanation:
A chemist prepares two acid solutions:
Solution 1: 3 parts sulfuric acid to 7 parts water
Ratio of sulphur to water: 3/7 (3:7)
Solution 2: 4 parts sulfuric acid to 9 parts water
Ratio of sulphur to water: 4/9 (4:9)
___________________________________________________
Part A: (using ratios to determine which solution is more acidic)
First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.
Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63
Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63
Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.
Mathematical Line (Not sure what you would call this lol): 28 > 27
Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)
Equation of solution 1: y = 3/7x
Equation of solution 2: y = 4/9x
Please find attachment for graph.
Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)

A deli offers a lunch-special that comes with soup, a sandwich, and a dessert. The soup choices are tomato or onion, the sandwich choices are ham, chicken, tuna, or pastrami, and the dessert choices are cake or pie.
a. Would this problem best be solved by using a table, a list, or a tree diagram. Explain your answer.
b. Use one of those methods to determine the size of the lunch-special sample space.
Answer:
A. This problem would best be solved using a tree diagram.
B. In order to solve it, you would construct a tree with the first soup choices growing into the other options. Then, after listing every alternative, you could either add them all up to obtain your answer or you could just use the formula 2*4*2=16, which would result in 16 possibilities.

Graph y+9=−3x
Identify the x-intercept
Answer:
formula is y=mx+b
the b(y-intercept) is -3x and m(slope) is 9.
In the graph, you would start at -3x on the y-axis (since it's on the y-intercept)
put your dot on -3x and move up 9.
you should land on positive 7(on the y axis)
9 must be a fraction so it would be 9/1
so, move once to the right on positive 7.
sorry couldn't show you.

help 15 points (i have to write 20 characters so don't mind this )
Answer:
C
Step-by-step explanation:
First find the area of the entire figure.
L= 36
W = 20
Area = 36 * 20 = 720
Find the area of the left right triangle.
Height = 20
Base = 1/2 * 36 = 18
Just as an aside, let me be a little grumpy for a moment. You should never have to guess what a dimension is on a diagram. It's sloppy. However for this problem you have no choice. But you could think to complain to your teacher.
Area = 1/2 * base * height
Area = 1/2 * 18 * 20 = 180
Find the area of the bottom right triangle.
The height is 1/2 20 = 10
The base is 36
Area of the lower triangle = 1/2 * 36 * 10 = 180
Area of the shaded figure = 720 - 180 - 180 = 360

Which expression is equivalent to -1/3 ( 6x + 15 ) - 3?
a) -2x + 12
b) -2x + 2
c) -2x - 2
d) -2x - 8
The correct answer is (D) -2x - 8.
To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:
-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3
Then we can simplify using the properties of multiplication and division:
-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3
Finally, we can combine like terms:
-2x - 5 - 3 = -2x - 8
The correct answer is therefore (D) -2x - 8.✅

2. Angle G= 55 degrees
Picture 2:-
1. Scale factor= 1/4 (I'm not sure about this but this is what I think it is ;-;)
2. Value of y= 28 cm
Picture 3:- [Picture 3 is cropped so I'm guessing its the last one so imma answer those questions :D]
1. Scale factor= 5 (Again I'm not sure but its my best guess)
2. Value of z= 5
Picture 4:-

-By The Organic Chemistry Tutor
It'll help you understand how we solve these questions
Well anyways i hope this clears your concepts :D
Answer:
Step-by-step explanation:
EH is 12cm as the shape has been enlarged by scale factor two (all sides have been multiplied by 2).
Angle G remains the same at 55 degrees.
PART A
Scale factor for the triangle = 1/4
Value of y = 28cm
3) z = 5, scale factor = 5

Scale factor = 4
Side b = 12cm
