You take a 200 milligram dosage of aspirin. During each subsequent hour, the amount of medication in your bloodstream decreases by about 35% each hour. What level of aspirin (mg) will be in your bloodstream in 4 hours. NEED ANSWER URGENT!!!
Answer: The level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.
Step-by-step explanation:
If the amount is decreasing by r%, then the final amount is given by :-
[tex]A=P(1-r)^t[/tex]
, where P = initial value , t= time
Given: P= 200 milligram, r= 35% = 0.35, t= 4 hours
The level of aspirin (mg) will be in your bloodstream in 4 hours = [tex]200(1-0.35)^4[/tex]
[tex]=200(0.65)^4\\\\=200\times 0.17850625\\\\=35.70125\approx35.70 \ mg[/tex]
Hence, the level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.

= 600 planes.
The planes in a year will be:

Jacob went on a fishing trip. This year he caught 30 fish, which is six more than twice the number he caught last year. How many fish did Jacob catch last year?
Answer:
12 fish
Step-by-step explanation:
You need to work this problem backwards. If he caught 30 fish, which was six more than twice the number he caught last year, you would start by subtracting six, leaving you with 24. Then you'd have to divide by 2, because it was twice plus six as many fish, which would give you 12 fish.
[tex]\frac{30-6}{2}[/tex] = x
[tex]\frac{24}{2}[/tex] = x

A right triangle with vertices labeled as A, B, and C. Side C B is the base, and the top vertex is A. Side A B contains a midpoint D. A line segment drawn from C to D bisects angle A C B into two parts labeled as A C D and B C D. Angles A C D and B C D are marked with single arc. Side A C is labeled as 3. Base C B is labeled as 4. Segment A D is labeled as 2.25. Segment B D is labeled x.
Use triangle bisect or theorem.
Set up proportion:
X/ 2.25 = 4/3
Cross multiply:
3x = (4 x 2.25)
3x = 9
Divide both sides by 3:
X = 3
Which equation represents this situation? y = 1.25x ) Which graph represents the situation?
The second graph represents the situation y=1.25x which has slope 1.25.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation is y= 1.25x
Slope is 1.25
Now let us plug in (1, 1.25) in the equation
1.25=1.25(1)
Hence, the second graph represents the situation y=1.25x which has slope 1.25.

The pyramid pictured below has a total surface area of 156 feet squared find the missing measurement
10 points is all i have
Answer:
maybe 36
Step-by-step explanation:
but can u help me What is the surface area of a square-based pyramid with a base length of 5 m and a slant height of 3 m?
Enter your answer in the box.
The missing measurement is 10 feet.
What is pyramid?A three-dimensional shape is a pyramid. A pyramid's flat triangular faces unite at a common point known as the apex and have a polygonal base. The bases are joined to the peak to create a pyramid. The lateral face is a triangle face formed by the connection of each edge of the base to the apex.
To find the surface area of the pyramid, we can use the following formula,
A = (½)Pl + B.
Where P is the base perimeter, l is the slant height and B is the base area.
Here, the base is square-shaped.
Now, let the slant height be x.
A = (1/2)(4 × 6) (x) + (6)²
156 = 12x + 36
12x = 156 - 36
12x = 120
x = 10 feet.
Therefore, the required height is 10 feet.

Find the area of the shaded part (π=22/7)
Answer:
42cm square
Step-by-step explanation:
Frist find the area of the square. 14*14
Then find the Area of the circle.- (radius) one side of the square is the diameter so, diameter divided by 2 - 14/2=7
After that subtract the area of circle from the area of the square.
Answer:
first we find the area of the square.
area of square=side²
area of square =14²
area of square=196cm²
area of circle=pi×radius²
radius=14/2=7
area of circle=22/7×(7)²
area of circle =22/7×49
area of circle =154cm²
area of shaded region=area of square - area of circle
area of shaded= 196cm²-154cm²
area of shaded=42cm²
The function c ( x ) = 63 ⋅ ( 1.03 ) x models the cost in dollars, c , of 1 ounce of a certain chemical used in a laboratory. x represents the number of years since 1990.
Does the cost of the chemical increase or decrease with time?
Group of answer choices
Increase
Decrease
9514 1404 393
Answer:
increase
Step-by-step explanation:
Your cost function appears to be an exponential function of the form ...
c(x) = (initial cost)·(growth factor)^x
When the growth factor (1.03) is greater than 1, it means the exponential function is increasing with x (time).
The cost function increases with time.

Answer: The answer is C) J' (3,-1), K' (1,-4)
Step-by-step explanation: First, you need to find the location of J, which is located in Quadrant III. You go left 3, and go down 1, making the coordinates of J (-3,-1). Next, you need to find the location of K, which is also located in (-1, -4).
So, the question asks, "What are the coordinates of J' and K' after JK is reflected across the y-axis?"-- Well, first, which line is the x-axis, and which line is the y-axis?
The x-axis is the line that is horizontal(Across) while the y-axis is the line that is vertical( Up and Down).
So you bring J and Ks coordinated over the y-axis to Quadrant IV(4). You already know their original coordinates, so you place the as you would in the picture above, except that the line would be reflected.

What is the rule that describes a reflection across the line y = x?
rx = y(x, y) →
Answer:
D I think
Step-by-step explanation:
GH=5 5; <H = 90
1. The mapping of the vertices of ΔDEF will be;
D(2, –4) → D' (-4, 2)
E(1, –1) → E' (-1 , 1)
F(5, 1) → F' (1, 5)
2. The rule of the reflection across the line y = x is;
[tex]r_{x} = _{y} (x , y)[/tex] → [tex]r_{y} = _{x} (y , x)[/tex]
What is Refection?
Reflection is a type of transformation that flip a shape in mirror line, so that each point is the same distance from the mirror line as its reflected point.
Given that;
The coordinates are,
D = (2, –4)
E = (1, –1)
F = (5, 1)
Now,
By the given image,
The mapping of the vertices of ΔDEF is;
D(2, –4) → D' (-4, 2)
E(1, –1) → E' (-1 , 1)
F(5, 1) → F' (1, 5)
And, The rule of the reflection across the line y = x is;
[tex]r_{x} = _{y} (x , y)[/tex] → [tex]r_{y} = _{x} (y , x)[/tex]
Because in the image its shows the line of reflection.
Therefore,
1. The mapping of the vertices of ΔDEF will be;
D(2, –4) → D' (-4, 2)
E(1, –1) → E' (-1 , 1)
F(5, 1) → F' (1, 5)
2. The rule of the reflection across the line y = x is;
[tex]r_{x} = _{y} (x , y)[/tex] → [tex]r_{y} = _{x} (y , x)[/tex]

Which words have vertical symmetry for all of the letters in the word? Check all that apply. MOM DIZZY HIT SEAT WAXY
Answer: 1, 3, 5
1.) MOM 3.) HIT 5.) WAXY
Step-by-step explanation: i hope this helps :)
The words in which all letters have vertical symmetry are MOM, HIT, and WAXY so options (A),(C), and (E) are correct.
What is symmetry?If two figures look an exact shape but their size could be small or big then both figures are called similar figures.
When anything has identical pieces facing one another or revolving around an axis, it is said to be symmetrical.
Vertical symmetry is the way by which a latter will completely coincide about a vertical axis.
For example word "A".
If we take a vertical axis in the mid of the word "A" then about this axis the whole word will coincide by left and right.
Thus, another words are M, O, T, Y, H, X.
The words containing the above letters are MOM, HIT, and WAXY.
Hence "The words in which all letters have vertical symmetry are MOM, HIT, and WAXY".

Answer:

Step-by-step explanation:
Since complementary angles add up to 90 degrees, we would need to add 37 and x to equal 90 degrees. Therefore, x + 37 equals 90 degrees. As for solving, subtract 37 from both sides and you are left with x = 53.
