cell? Write the final answer in scientific notation with the correct number of significant digits.
A. 06.25 x 10²
B. 2x10²
C. 6x 10¹
D. 16 x 10¹
The number of times the bacterial cell is smaller than the amoeba cell is 1.6 * 10^-10
How many times smaller is the bacterial cell than the amoeba cell?The given parameters are:
Bacteria cell = 4 x 10^-6 m
Amoeba cell = 2.5 x 10^4 m
The number of times (n) is calculated as
n = Amoeba cell/Bacteria cell
This gives
n = (4 x 10^-6 m)/(2.5 x 10^4 m)
This gives
n = 1.6 * 10^-10
Hence, the number of times the bacterial cell is smaller than the amoeba cell is 1.6 * 10^-10

In the segment below, QV = 23. QT = 8. TR = RS = SV.
Answer:
RS = 5
QS = 18
TS = 10
TV = 15
Step-by-step explanation:
Given QV = 23 and QT = 8 and TR = RS = SV
now, we subtract the length of QT from the whole line, QV
23 - 8 = 15 then we divide this by 3 because TR = RS = SV so there must be 3 equal pieces
15 ÷ 3 = 5
RS = 5
QS = QT + TR + RS so
QS = 8 + 5 + 5
QS = 18
TS = TR + RS so
TS = 5 + 5 and
TV = TR + RS + SV
TV = 15

Step-by-step explanation:
(a)
the sum of all internal angles in a polygon with n sides is
(n - 2)×180.
since in a regular polygon all angles are equally large, we get for one internal angle :
(n - 2)×180/n
for our hexagon this means the internal angle is
(6 - 2)×180/6 = 4×30 = 120°
(b)
the area of the hexagon is (as the graphic so nicely suggests) the sum of the areas of all 6 inner triangles.
the area of a triangle is
baseline × height / 2
baseline = 10 cm
the height (from the tip of the triangle down to the baseline in a right angle) is half of 17.3 cm, because these 17.3 cm are the sum of the 2 heights of 2 triangles placed tip to tip.
so, height = 17.3/2 = 8.65 cm
the area of one of the triangles is therefore
10 × 8.65 / 2 = 5 × 8.65 = 43.25 cm²
the total area of the hexagon is then
6 × 43.25 = 259.5 cm²

Temperature Suppose there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 46.2°F, what
will be the temperature when the plane reaches an altitude of 10,000 ft?
The temperature will be
PF. (Type an integer or a decimal.)
The temperature at 10,000 feet altitude will be 30.2 ° F.
We are given that:
As the airplane moves 1000 feet above the ground, the temperature drops by 1.6 ° F.
Now, the temperature on the ground is given as
Temperature on ground = 46.2 ° F
Now, the plane is at the altitude of 10,00 feet.
We need to tell the temperature at that altitude.
At 1000 feet, temperature drops by = 1.6 ° F.
At 10000 feet, the temperature will drop by = 1.6 ° F. × 10,000 / 1000
= 16 ° F.
So, the temperature will be = 46.2 ° F - 16 ° F

How to derive the expression of a quadratic equation from a graph
The picture presents us the graph of a parabola, whose algebraic expression is a quadratic equation. In accordance with fundamental theorem of algebra, a quadratic equation can be derived by knowing three distinct points on Cartesian plane.
If we know that (x, y) = (0, 14), (x, y) = (3, 5) and (x, y) = (6, 14), then the coefficients of the quadratic equation in standard form:

6. The measure of each angle is m∠ E = 46°, m∠ D = 46°.
Angle of elevation from point A to B (∠ E ) is the angle between the horizontal line from A to B.
And, Angle of depression from B to A ( ∠D ) is the angle from the horizontally downward line from B to A.
As we can see that all the horizontal lines are in parallel to each other,
Alternative Interior Angle : When two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent.
With the help of above theorem,
Angle of elevation from point A to B = Angle of depression from point B to A,
∠E and ∠D are interior opposite angles.
Then, m ∠ E = m ∠ D
3x + 1 = 2(x + 8) ( Given )
3x + 1 = 2x + 16
x = 15,
So, m∠ E = 3x + 1 = 45 + 1 = 46°
Hence, m∠D = 46°
7. The measure of each angle is m∠ E = 20°, m∠ D = 20°.
By following same method as given above we will solve this question.
So, As we know that
Angle of elevation from point A to B = Angle of depression from point B to A,
∠E and ∠D are interior opposite angles.
Then, m ∠ E = m ∠ D
5(x - 2) = (x + 14)
5x - 10 = x + 14
5x -x = 14 + 10
4x = 24
x = 24/4 = 6
So, m∠ D = (x + 14) = 6 + 14 = 20°
Hence, m ∠ E = 20°

Mom is getting food ready for my birthday party! Including me, there will be 28 people at the party. Mom is baking cookies for us! She can bake 24 cookies per batch. How many batches should I tell Mom to make so we can each have 5 cookies?
Answer:
The answer would be six batches of cookies.
Answer:
6 batches
Step-by-step explanation:
so 28 people including you
24 cookies per batch
5 cookies each
24 cookies in each batch, if you round that up it would be 30 and 30 x 5 = 150, so instead of rounding the amount of cookies, add 1 more to the amount you multiply 24 by
then it would be 24 x 6 = 144
now divide that by 28
144/28= 5 1/6
it would take 6 (7 if everyone gets whole numbers of cookies because It would be a fraction if not 7) batches to make sure everyone gets cookies
double check:
24 times 6 = cookies
144/28= 5 1/6
