2 × 10^12 red blood cells have a total mass of 90 grams.
Work out the average mass of 1 red blood cell.
Give your answer in standard form.
Answer:
2×10¹² cells → 90 g
mass of 1 red blood cell : 90÷(2×10¹²) = 45×10^-12 g = 4.5×10^-11 g
If 2 = 6, what is the degree measure of 5?
A. 80
B. 220°
C. 60°
D. 120°
Answer:
60°
Step-by-step explanation:
We know that 2 and 6 = 60 degrees, so we add 60 + 60 which equals 120, now subtract 120 by 180 and you get 60 degrees.

Find the perimeter and the area of the figure.
6 cm
7 cm
9.5 cm
6.5 cm
The perimeter and the area of the composite figure are 29 centimeters and 49.5 square centimeters, respectively.
How to determine the perimeter and the area of the figure
In this problem we have the representation of a composite figure, the result of the combination of a rectangle and a triangle. The perimeter of the figure is the sum of the sides and the area of the composite figure is the result of suming the areas of the rectangle and triangle:
Rectangle
A = b · h
Triangle
A = 0.5 · b · h
Where:
b - Baseh - HeightA - AreaAnd the perimeter and the area of the composite figure are now computed:
Perimeter
p = 6 cm + 7 cm + 6.5 cm + 9.5 cm
p = 29 cm
Area
A = 0.5 · (6 cm) · (2.5 cm) + (6 cm) · (7 cm)
A = 7.5 cm² + 42 cm²
A = 49.5 cm²

Based on the diagram, which expresses all possible
lengths of segment AB?
A. AB = 25
B. 27 < AB <81
C. AB = 85
D. AB < 27 or AB > 81
Answer:
B
Step-by-step explanation:
Given 2 sides of a triangle then the third side is in the range
difference of 2 sides < AB < sum of 2 sides , that is
54 - 27 < AB < 54 + 27
27 < AB < 81 → B

Directions:Find the measures of the missing angles in each trapezoid. Will give brainliest for full answer.Posted for the 4th time :(
Step-by-step explanation:
m<M=m<L=110°
m<N=m<O=x → 2x+2(110°)=360° → x=70°
m<E=180°-22°=158°
m<A=360°-(88°+22°+158°)= 92°
m<D=m<O=61°
m<S=m<G=x → 2x+2(61°)=360° → x=238/2 = 119°
Answer:
Step-by-step explanation:
1)∠L + ∠O = 180 {Co interior angles}
110 + ∠O = 180
∠O = 180 - 110
∠O = 70
Base angles of isosceles trapezoid are equal
∠M = ∠L
∠M = 110
∠O = ∠N
∠N = 70
2) ∠c + ∠A = 180 {Co interior angles}
88 + ∠A = 180
∠A = 180 -88
∠A = 92
∠D + ∠E = 180 {Co interior angles}
22 +∠E = 180
∠E = 180 - 22
∠E = 158
3) ∠O + ∠G = 180 {Co interior angles}
61 + ∠G = 180
∠G = 180 - 61
∠G = 119
Base angles of isosceles trapezoid are equal
∠D = ∠O
∠D = 61
∠S = ∠G
∠S = 119

for 7 we only need Pythagoras's theorem, know it?
[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex]
out of curiosity.. does the above formula seem "impossible" ? or does it make sense?
[tex]c^{2}[/tex] = [tex]12^{2}[/tex] + [tex]16^{2}[/tex]
[tex]c^{2}[/tex] = 144 + 256
[tex]c^{2}[/tex] = 400
c = [tex]\sqrt{400}[/tex]
c = 20
x= 20
for 8 we do need the above list of trig functions. we want to find the Hyp x and we know an angle and the adjacent side sooo use Cos .. b/c we can see it's got those parts in it
Cos(60) = 18 / x
I'll show you the algebra we need to use to get this formula so that we can find x
A = B / x ( this is how it looks above )
x = B / A , now just put in the parts
x = 18 / Cos(60) now solve it w/ your calculator.. :P Cos(60) happens to be 1/2 so you could have done this w/o your calculator :/
x = 36

Give the center and radius of the circle x2+y2=25
A) (2,3)r=5
B) (0,0)r=5
C) (0,0)r=25
D) (3,2)r=25
Answer:
B) (0,0); r=5
Step-by-step explanation:
A circle's standard form is (x-h)^2+(y-k)^2=r^2
The center is (h, k) and the radius is r.
So, here the center would be (0, 0) and the radius would be square root 25, or 5.
Answer:
(0,0) r=5

The decimal form of 1/3 is a repeating decimal. Are all the multiples of 1/3 also repeating decimals? Explain.
plz help
Answer:
No.
Step-by-step explanation:
1=3*1/3
2=6*1/3
3=9*1/3
......
Yes, All the multiples of 1/3 also repeating decimals.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The decimal form of 1/3 is a repeating decimal.
Now,
Since, The decimal form of 1/3 is a repeating decimal.
As, 1 / 3 = 0.33333...
And, Some of the multiples of 1/3 are;
1 / 3 = 1×2 / 3×2
= 2 / 6
= 0.33333....
And, 1 / 3 = 1×3 / 3×3
= 3 / 9
= 0.33333....
1 / 3 = 1×4 / 3×4
= 4 / 12
= 0.33333....
Thus, Yes, All the multiples of 1/3 also repeating decimals.

A point is chosen at random on AK what is the probability that one point will be on BG?
Answer:
11/21.
BG has a total of 11 points (when you include 0), and there are 21 points total. 11/21 cannot be simplified, your final answer is 11/21.
The required probability is 11/21 that one point will be on BG.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
We have been given that the number line which has a point is chosen at random on AK.
As per the given question, the required solution would be as:
Since BG has a total of 11 points (when you include 0),
so, the number of favorable outcomes : 11
There are 21 points in total, then the total number of outcomes : 21.
So, the probability that one point will be on BG would be as:
⇒ 11/21
