A seed weighs 0.00002421 ounces. What is this value in correct scientific notation?
A) 2421 x 108
B) 2.421 x 105
2.421 x 10-5
D 2421 x 10
-8
Answers
Answer:
C) 2.421 x 10^-5
Step-by-step explanation:
A negative exponent on a power of ten will make the decimal point go back that amount of times to the left, making it a lesser number. A positive exponent will cause it to move to the right, making the number greater. We aren’t going to need to make any of the numbers being multiplied greater, so we can eliminate the first two. Then we need to solve the others. We can do this by moving the decimal the amount of times that we see the exponent equals. Since C is -5, we move it to the left 5 times, and get the weight of the seed; 0.0002421.
Hope This Helped!

The ratio of the side length of square A to the length of Square B is 4:9 The side length of square A is 12 yards. What is the perimeter of Square B
Answers
Step-by-step explanation:
side A / side B = 4/9
side A = 12 yards
=>
12 / side B = 4/9
12 = side B × 4/9
9×12 = side B × 4
side B = 9×12/4 = 9×3 = 27 yards
perimeter of B is 4×side B = 4×27 = 108 yards

Write the recurring decimal 0.05 as a fraction in its simplest form
Answers
Answer:
1/20
Step-by-step explanation:
Step 1: Write the given number as the numerator and place 1 in the denominator right below the decimal point followed by the number of zeros required accordingly.
In this case, 0.05 has two numbers after the decimal, so, we place 100 in the denominator and remove the decimal point. This will make it 5/100
Step 2: Then, this fraction can be simplified. 5/100 = 1/20
Thus, 0.05 as a fraction is written as 1/20
Answer:
Step-by-step explanation:
let the fraction be a
a*100.....=0.05*100
100a......=05.00
99a....=0.05
100a= 5.00
99a= 0.05
a= 4.95/99

Explanation:
1kg in household measurement is equal to 35.274 ounces. 35.274*9=317.466 ounces.
1kg is also equal to 2.205 lbs. 9*2.205=19.8416
9 kg is also equal to 9000 grams, but grams are not a part of the household measurement system
a) 9000 grams. b) 9000 ounces. c) 19.8 ounces. d) 19.8 pounds.

Hypotenuse = 5
4 / 2 = 5 / x
2 = 5 / x

Two angles in a triangle are have the same measurement. The third angle is 12 degrees less than
the first angle. What are the measurements of angle 1, 2 and 3? (hint: you will need to know
how many degrees are in an triangle)
Answers
a + a + b = 180
2a + b = 180
Next, b is 12 degrees less than a so:
a - 12 = b
2a + a - 12 = 180
3a - 12 = 180
Add 12 to both sides
3a = 192
Find a:
a = 192 / 3
a = 64
This means angle 1 and angle 2 are equal to 64 degrees and angle 3 is 52 degrees
To check:
64 + 64 + 52 = 180 degrees
6. Three cards are drawn from an ordinary deck and not replaced. What is the
probability of getting 3 spades?
Answers
We want to find the probability of randomly drawing 3 spades from a standard deck.
The probability of getting 3 spades is 0.0129
Let's see how to get that probability.
A standard deck has 52 cards, 13 of them are spades.
The probability of randomly drawing a spade card is given by the quotient between the number of spades and the total number of cards.
So for the first spade card, the probability is:
p = 13/52
For the second card, take in mind that we already drew a spade card, so now there are 12 spade cards and 51 cards in total, so we have:
q = 12/51
For the final card, there will be 11 spade cards and 50 cards in total, but we will have:
k = 11/50
The joint probability (this is, the probability of getting the 3 spade cards one after the other) is equal to the product of the individual probabilities, so we will get:
P = p*k*q = (13/52)*(12/51)*(11/50) = 0.0129
The probability of getting 3 spades is 0.0129

solve for completing the square x^2-12x+11=0
Answers
Answer:
x = 6 ± 5
Step-by-step explanation:
x² - 12x + 11 =0
x² - 12x = -11 Now add this number to both sides of the equal sign (1/2 of the coefficient of x-term squared)
x² - 12x +36 = -11 + 36 1/2(-12)² = 36
(x - 6)(x - 6) = 25
(x - 6)² = 25
[tex]\sqrt{(x-6)}[/tex]² = [tex]\sqrt{25}[/tex] square root of both side of the equation
x - 6 = ± 5 (5)² = 25 and (-5)² = 25
x = 6 ± 5

Henry draws triangle FGH. Then, he translates that triangle to create triangle F'G'H'. The distance from F to F' is 4 centimeters. What is the length of sides GG'? a. 2 cm b. 3 cm c. 4 cm d. 6 cm
Answers
The length of sides GG' when the distance from FF' is 4 cm is also 4 cm.
A translation is a type of transformation that takes each point in a figure and slides it the same distance in the same direction.
When you perform translations, you slide a figure left or right, up or down. This means that, in the coordinate plane, the coordinates for the vertices of the figure will change.
It is given that Henry translates the ΔFGH to create ΔF'G'H'.
FF' = 4cm.
Translation is a rigid transformation. In translation, every point of the object must be moved by same distance and in the same direction.
In other words the distance between corresponding points are same.
GG' =?
Since G and G' are corresponding points, so
GG' = FF'
GG' = 4 cm
The length of GG' is 4 centimeters.
Hence, When the distance from FF' is 4 cm, the length of sides GG' is similarly 4 cm. so option C is the correct answer.

First we calculate (h) using the following sine ratio
[tex]\mathbf{sin(75) = \frac{h}{40}}[/tex]
Make h the subject
[tex]\mathbf{h = 40sin(75)}[/tex]
Next, we calculate (z) using the following sine ratio

Make z the subject
[tex]\mathbf{z= \frac{h}{sin(10)}}[/tex]
Substitute [tex]\mathbf{h = 40sin(75)}[/tex]
[tex]\mathbf{z= \frac{40sin(75)}{sin(10)}}[/tex]
[tex]\mathbf{z= 222.5 ft}[/tex]
Hence, the length of the zip line is 222.5 ft
(b) The height, h
In (a), we have
[tex]\mathbf{h = 40sin(75)}[/tex]
Evaluate
[tex]\mathbf{h = 38.6}[/tex]
Hence, the height where the ladder rests against the tree is 38.6 ft
(c) The distance, b
To do this, we make use of the following sine ratio
[tex]\mathbf{sin(15) = \frac{b}{40}}[/tex]
Make b the subject
[tex]\mathbf{b = 40sin(15)}[/tex]
[tex]\mathbf{b = 10.4}[/tex]
Hence, the distance between the base of the ladder and that of the tree is 10.4 ft
(d) Distance, B
To do this, we make use of the following sine ratio
[tex]\mathbf{sin(80) = \frac{B}{z}}[/tex]
Make B the subject
[tex]\mathbf{B = z\ sin(80)}[/tex]
Substitute [tex]\mathbf{z= 222.5 ft}[/tex]
[tex]\mathbf{B = 222.5\ sin(80)}[/tex]

The distance between the base of the tree and the spot where the zip line is anchored to the ground is 137.0 ft
(a) Length, z
First we calculate (h) using the following sine ratio
Sin(75)=h/25
Make h the subject
h=25sin(75)
Next, we calculate (z) using the following sine ratio
Sin(10)=h/z
Make z the subject
z=h/sin(10)
Substitute
h=25sin(75)
z= 25sin(75)/sin(10)
z=139.1 ft
Hence, the length of the zip line is 139.1 ft
(b) The height, h
In (a), we have
h=25sin(75)
Evaluate
h=24.1 ft
Hence, the height where the ladder rests against the tree is 24.1 ft
(c) The distance, b
To do this, we make use of the following sine ratio
sin(15)=b/40
Make b the subject
b=25sin(15)
b= 6.5 ft
Hence, the distance between the base of the ladder and that of the tree is 6.5 ft

To do this, we make use of the following sine ratio
sin(80)=B/z
Make B the subject
B=z sin(80)
Substitute
z=139.1 ft
B=139.1 sin(80)
B=137.0 ft
