1) About how much medicine did he make in grams?
Dr. Mann mixed
9.357 g of chemical A,
12.082 g of chemical B,
7.502 g of chemical C
We can determine total amount of medicine that was prepared by Dr. Mann by summing up the chemicals (A,B,C)
=( 9.357grams of A + 12.082grams of B+ 7.502grams of C)
= 28.941 grams in total
The next step is to round up those chemicals value to their nearest tenth as asked by question
Dr. Mann mixed
9.357 g of chemical A= 9.4grams
12.082 g of chemical B,=12.1grams
7.502 g of chemical C =7.5grams
2)Estimate the amount of each chemical by rounding to the nearest tenth of a gram before finding the sum.
Then the sum after rounding up to nearest tenth is
(9.4grams +12.1grams + 7.5grams)
=29 gram

A submarine starts at the surface of the water and then travels 95 meters below sea level in 19 seconds. If the submarine traveled an equal distance each second, what integer gives the distance traveled each second? a. –1805 c. –5 b. 1805 d. 5
Answer:
-5
Step-by-step explanation:
Given that:
Total distance traveled from surface of water = 95 meters
Total travel time = 19 seconds
If equal distance Is traveled per second :
Distance traveled per second :
Total distance covered / total time taken
95 meters / 19 seconds
= 4.842 meters / second
Since it travels below sea level ( negative).
Hence distance traveled per second to the nearest integer = - 5 m/s

Answer:
A. x=8 y=21
Step-by-step explanation:
line l and line m are parallel, and both angles that have x in the values are on the same side, so they are equal to each other.
7x+12=12x-28
+28 +28
7x+40=12x
-7x -7x
40=5x
/5 /5
8=x
Since A is the only choice that has x=8, it must be the right answer.
Answer:
x = 8, y = 21
Step-by-step explanation:
parallel means they're equal so..
7x + 12 = 12x - 28
-7x -7x
12 = 5x -28
+28 +28
40 = 5x
8 = x
plug in 8 to 12x - 28
12(8) - 28
96 - 28 = 68
180 - 68 = 112
9y - 77 = 112
+77 +77
9y = 189
y = 21

Find the equation of OP.
The required equation of a circle P is x² + (y −3)² = 4. The correct answer is option (F).
As per the shown figure, the circle P with a center at (0, 3) and a radius is 2 units.
The center of the circle is given as (h,k) = (0, 3)
So the equation of the circle is:
⇒ r² = (x − h)² + (y − k)²
Substitute the values of r, h, and k in the above equation,
⇒ 2² = (x − 0)² + (y −3)²
⇒ 4 = x² + (y −3)²
⇒ x² + (y −3)² = 4
Hence, the equation of a circle P is x² + (y −3)² = 4.

Answer:
angle 1= 122
Step-by-step explanation:
We know this is an isosceles triangle because of the two marks indicating that the lines have the same measure and therefore have the same angle measurement as well.
Frist let's find the the 2 smaller sides by subtracting 64 from 180 and dividing by 2 (both sides are the same).
180-64=116, 116/2=58,
Now we know the measure of the smaller angles, and notice that the smaller angle on the forms a linear pair (both add up to 180 degrees) with angle 1
so, 180-58= angle 1
Angle 1= 122

Step-by-step explanation:
Convert miles to yards and hours to minutes:

2 hours x 60 = 120 total minutes
26400 yards / 120 minutes = 220 yards per minute.
A city planner uses a coordinate grid to model the streets of a city. Each unit on the coordinate grid represents one city block. City hall is located at (0,0).The downtown area is represented by rectangleABCD, which has the vertices listed below. A(9,9) B(9,−2) C(−8,−2) D(−8,9) What is the perimeter of the downtown area?
Answer:
The perimeter of the downtown area is 56 units.
Step-by-step explanation:
From Geometry we know that perimeter ([tex]p[/tex]), dimensionless, is the sum of the lengths of the rectangle, that is, its 4 sides:
[tex]p = AB + BC + CD + DA[/tex] (1)
Where [tex]AB[/tex], [tex]BC[/tex], [tex]CD[/tex] and [tex]DA[/tex] are the sides of the rectangle, dimensionless.
Each side length is determined by Pythagorean Theorem:
[tex]AB = \sqrt{(9-9)^{2}+(-2-9)^{2}}[/tex]
[tex]AB = 11[/tex]
[tex]BC = \sqrt{(-8-9)^{2}+[-2-(-2)]^{2}}[/tex]
[tex]BC = 17[/tex]
[tex]CD = \sqrt{[-8-(-8)]^{2}+[9-(-2)]^{2}}[/tex]
[tex]CD = 11[/tex]
[tex]DA = \sqrt{[9-(-8)]^{2}+(9-9)^{2}}[/tex]
[tex]DA = 17[/tex]
Then, the perimeter of the downtown area is:
[tex]p = 11+17+11+17[/tex]
[tex]p = 56[/tex]
The perimeter of the downtown area is 56 units.
Answer:
56 units

According to the graph, what is the experimental probability of selecting the letter T?
1/20
4
1/4
1/5
Answer: the answer is 1/5 I put 4 and got it wrong, after submitting the test it showed me the answer
Experimental probabilities are based on the results of an experiment.
The experimental probability of T is (d) 1/5
From the graph, we have:
[tex]\mathbf{M = 6}[/tex]
[tex]\mathbf{A = 3}[/tex]
[tex]\mathbf{T = 4}[/tex]
[tex]\mathbf{H = 7}[/tex]
So, the experimental probability of T is:
[tex]\mathbf{P(T) = \frac{T}{M + A + T + H}}[/tex]
This gives
[tex]\mathbf{P(T) = \frac{4}{6 + 3 + 4 + 7}}[/tex]
[tex]\mathbf{P(T) = \frac{4}{20}}[/tex]
Simplify
[tex]\mathbf{P(T) = \frac{1}{5}}[/tex]
Hence, the experimental probability of T is (d) 1/5
