Answer:
8 I belive is C and 9 I think is D :)
Answer and Step-by-step explanation:
Distance is the numerical measurement to find the space or interval between two objects. Distance also refers to physical length. Point x to point y distance is denoted as |xy|
There are many ways to find out the distance, distance between two objects or two points. The efficient way of finding the distance between two points is given below. Mathematically, the distance between two points on a coordinate plane can be determined by using the distance formula, which is:
d =√((x2-x1)2+(y2-y1)2),
Where (x1, y1) and (x2, y2) coordinates, and d is the distance.
The middle point between these two points is known as midpoint and can find out by using the formula
Midpoint = a + b /2.
The distance between two points number line can also be calculated by using the formula:
AB =|b –a| or |a-b|.
I think it represent the a point on a graph
Answer:
90% Solution
Step-by-step explanation:
5% of 90 + 90% of x = 75% of (90 + x)
5×90/100 + 90x/100 = 75×90/100 + 75x/100
Or 90x/100 - 75x/100 = 75×90/100 - 5×90/100
Or 15x/100 = 90×70/100
Or X = 420ml
You Will Need ML Of The 90% Solution To Obtain ML Of The Desired 75% Solution.
Answer:
It is going to be less than 90 for sure
Step-by-step explanation:
Less than 40
so around the 30's
