Answer:-0.98
Step-by-step explanation:
A researcher performs an experiment to test a hypothesis that involves the nutrients niacin
and retinol. She feeds one group of laboratory rats a daily diet of precisely 32 units of niacin
and 22000 units of retinol. She uses two types of commercial pellet foods. Food A contains
0,12 unit of niacin and 100 units of retinol per gram. Food B contains 0,20 unit of niacin and
50 units of retinol per gram. How many grams of each food does she feed this group of rats
each day?
The amount in grams of food A and B she feeds this group of rats each day will be 2200003.84 gm and 1100006.4 gm respectively.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
Given that, she provides a certain set of lab rats with a daily meal that contains exactly 32 units of niacin and 22000 units of retinol. She uses two different brands of industrial pellet food.
If food A has 100 units of retinol and 0,12 units of niacin per gram.Niacin 0.20 units and retinol 50 units are both included in Food B per gram. The grams of each food she feeds this group A of rats each day is,
=32×0.12+22000×100
=2200003.84 gm
If food B contains 0,20 units of niacin and 50 units of retinol per gram.The grams of each food she feeds this group A of rats each day is,
=32×0.20+22000×50
=1100006.4
Thus, the amount in grams of food A and B she feeds this group of rats each day will be 2200003.84 gm and 1100006.4 gm respectively.

Find the greatest possible x-coordinate of point A such that for any point B on the y-axis between (-24) and 25, the segment AB has a common point with the line segment PQ, where P(5, -12), Q(5, 9).
Answer:
8.75
Step-by-step explanation:
You want the greatest possible x-coordinate of point A such that for any point B on the y-axis between (-24) and 25, the segment AB has a common point with the line segment PQ, where P(5, -12), Q(5, 9).
GeometryIf we designate the points on the y-axis as X(0, -24) and Y(0, 25), we find that point A must lie in the triangle bounded by lines XY, XP, and YQ. The x-coordinate of the point of intersection of lines XP and YQ will be the greatest x-coordinate that point A can have.
EquationsThe line through points (x1, y1) and (x2, y2) can be written as ...
(y2 -y1)(x -x1) -(x2 -x1)(y -y1) = 0
This equation is readily simplified to general form ax+by+c = 0.
Line XP
(-12-(-24))(x -0) -(5-0)(y -(-24)) = 0
12x -5y -120 = 0
Line YQ
(9 -25)(x -0) -(5 -0)(y -(25)) = 0
-16x -5y +125 = 0
We want the value of x that satisfies these equations. That can be found by subtracting the second equation from the first:
(12 -5y -120) -(-16x -5y +125) = (0) -(0)
28x -245 = 0
x = 245/28 = 8.75
The greatest x-coordinate is x = 8.75.

An element with a mass of 400 grams decays by 29.8% per minute. To the nearest
minute, how long will it be until there are 2 grams of the element remaining?
The time elapsed, to the nearest minute, until only 2 grams of the element remains is 15 minutes.
We have an element. The element has a mass of 400 grams. The element decays by 29.8% per minute. We need to find the time duration after which there will be only 2 grams of the element remaining. Let the initial mass of the element, the final mass of the element, the rate of decay, and the time elapsed be represented by the variables m, M, r, and t. We can write the equation as given below.
M = m(1 - r)^t
2 = 400(1 - 0.298)^t
0.005 = (0.702)^t
log(0.005) = t*log(0.702)
t = log(0.005)/log(0.702)
t = 14.97
The time taken, to the nearest minute, is 15 minutes.

well, we had a cylinder with 7mL of water, in the rock goes and kaboom the volume for the cylinder and its contents is 9 mL, well, the displaced water from the rock is equivalent to its volume, as Archimedes would properly point out, so since it was 7mL and now is 9mL well, the extra 2mL is the volume of the rock :).

The coordinates of the midpoint of segment FG are (3,-1) which was found using midpoint formula.
How to find midpoints of a line segment?When it comes to practical application, the midpoint formula is rather straightforward.
Step 1: Determine the line segment or the two ends.
Step 2: Determine their coordinates.
Step 3: Add the x coordinates of both ends and divide by 2.
Step 4: Adding the y coordinates of both endpoints, divide by 2, and complete the step.
Step 5: As you specify the coordinates of any point, write the values that were acquired in Steps 3 and 4.
Given: Endpoints of a line segment are F(2, -1) and G(-8, -1).
We need to find the coordinates of its midpoint.
Using midpoint formula,
(a,b) = (x₁ + x₂)/2,(y₁ + y₂)/2
= (2-8)/2,(-1-1)/2
= 3,-1
So, coordinates are (3,-1)

x = 0y = 3Step-by-step explanation:
Forming the equation,
→ 2x + 3 = -3x + 3
Now the value of x will be,
→ 2x + 3 = -3x + 3
→ 2x + 3x = 3 - 3
→ 5x = 0
→ x = 0/5
→ [ x = 0 ]
Then the value of y will be,
→ y = -3x + 3
→ y = -3(0) + 3
→ y = 0 + 3
→ [ y = 3 ]
Hence, the value of y is 3.

Note that because the graph is slightly deformed to the left, it is impossible to work out the exact bearing. Below, however, are steps on how to get the bearing of a map.
How do you work the bearings of a map?Calculate the angle clockwise from north to determine a bearing. Begin with the first site by drawing a vertical line symbolizing north. Draw a line from the starting point to the ending point. Calculate the clockwise angle formed by the north line and this line.
When measuring a bearing, three principles must be followed:
Always determine the angle counterclockwise.Always evaluate the angle from north to south.Always use a three-figure bearing (for example, 030° instead than 30°).Note that a bearing is an angle in degrees calculated clockwise from north in mathematics. Bearings are often specified in three figures. 30° clockwise from north, for example, is generally represented as 030°.

Rate of gems per chests = 600/2 = 300 g/c
In adventure B, when number of gems is 1500, we see that number of chests is 5. Thus;
Rate of gems per chests = 1500/5 = 300 g/c
In adventure C, when number of gems is 4800, we see that number of chests is 16. Thus;
Rate of gems per chests = 4800/16 = 300 g/c
