Answer:
190.85
Step-by-step explanation:
Priscilla has 4.3*10^8 strands of hair on her head. Diego has 8.7*10^5 strands of hair on his head. How many more strands of hair does Priscilla have than Diego? Express your answer in scientific notation.
====================================================
Work Shown:
4.3*10^8 = 4.3 * 10^(3+5)
4.3*10^8 = 4.3 * 10^3*10^5
4.3*10^8 = 4.3*1000*10^5
4.3*10^8 = 4300*10^5
Priscilla has 4300*10^5 strands of hair while Diego has 8.7 * 10^5 strands. Subtract the values out front: 4300-8.7 = 4291.3
Then tack on the "*10^5" portion to get 4291.3*10^5
The difference in the number of strands is 4291.3*10^5
Convert this to scientific notation to get the final answer.
4291.3*10^5 = (4291.3)*10^5
4291.3*10^5 = (4.2913 * 1000)*10^5
4291.3*10^5 = 4.2913 * 1000*10^5
4291.3*10^5 = 4.2913 * 10^3*10^5
4291.3*10^5 = 4.2913 * 10^(3+5)
4291.3*10^5 = 4.2913 * 10^8
Note: The number 4.2913 * 10^8 expands out to 429,130,000 which is a little over 429 million.
The local store sells small pieces of candy for $0.15 each. Shondra spent
$18.00 on this candy for her class party. The equation below can be used to
determine how many pieces of candy, c, that Shondra bought.
0.15 c = 18.00
How many pieces of candy did Shondra buy for the class party?
Answer:
120 pieces of candy
Step-by-step explanation:
To find c, you need to divide your know values, 18.00 and .15. So 18/.15 = 120.
Shondra bought 120 pieces of candy.

A rectangle measures 2 and 1/4 meters by 1 7/8 meters. What is it area u have to get a mixed fraction as the area plss help.
Answer:
4 1/8 m^2
Step-by-step explanation:
Given data
Length = 2 1/4 meters
Width= 1 7/8 meters
Area= Length* Width
Area= 2 1/4 * 1 7/8
Convert from mixed to simple fraction
Area= 9/4+ 15/8
Area= 18+ 15/8
Area= 33/8
Convert back to mixed fraction
Area= 4 1/8 m^2

Answer:
x=3.5
Step-by-step explanation:
Answer:
x=sqrt(12) or 2sqrt(3)
Step-by-step explanation:
You can just use pythagorean theorem for this.
We can do 4^2+x^2=8^2
This gives us 16+x^2=64.
Simplify: x^2=48
x=sqrt(48)
Now, we can find x!
We just have to do 6^2+x^2=sqrt(48).
We get 36+x^2=48
simplify: x^2=12
Now, x=sqrt(12) or 2sqrt(3)

What is the area in square feet for this shape?
Answer:
Area of figure = 68.13 feet² (Approx.)
Step-by-step explanation:
Given:
Length of rectangle = 9 ft
Width of rectangle = 6 ft
Diameter of semicircle = 6 ft
Find:
Area of figure
Computation:
Radius of semicircle = Diameter of semicircle / 2
Radius of semicircle = 6 / 2
Radius of semicircle = 3 ft
Area of figure = Area of rectangle + Area of semicircle
Area of figure = [Length x( Width] + [πr²]/2
Area of figure = [9 x 6] + [(3.14)(3)²]/2
Area of figure = [54] + [(3.14)(9)]/2
Area of figure = [54] + [28326]/2
Area of figure = [54] + [14.13]
Area of figure = 68.13
Area of figure = 68.13 feet² (Approx.)

Enter the number that belongs in
the green box.
Enter
Answer:
x = 88.2
Step-by-step explanation:
Reference angle = 10°
Opposite = x
Adjacent = 500
Apply TOA:
Tan 10° = x/500
Multiply both sides by 500
500*Tan 10° = x
88.1634905 = x
x = 88.2 (nearest tenth)

Let f(x)=e^x and g(x)=x+6. What are the domain and range of (g0f)(x)? domain: x > 0 range: y > 0 domain: x > 6 range: y > 0 domain: all real numbers range: y > 6 domain: all real numbers range: all real numbers\
Answer:
Domain and Range of g(f(x)) are 'All real numbers' and {y | y>6 } respectively
Step-by-step explanation:
We have the functions, f(x) = eˣ and g(x) = x+6
So, their composition will be g(f(x)).
Then, g(f(x)) = g(eˣ) = eˣ+6
Thus, g(f(x)) = eˣ+6.
Since the domain and range of f(x) = eˣ are all real numbers and positive real numbers respectively.
Moreover, the function g(f(x)) = eˣ+6 is the function f(x) translated up by 6 units.
Hence, the domain and range of g(f(x)) are 'All real numbers' and {y | y>6 } respectively.

For what values of x and y must each figure be a parallelogram?
Need help please, and explanation.
Answer:
y = 30
x = 60
Step-by-step explanation:
4y and 2y are consecutive angles, which means they are equal to 180° when added together
that is the same with x and (5x - 180)
to solve, you set the equations to 180
solving:
4y + 2y = 180
6y = 180
y = 30
x + 5x - 180 = 180
6x = 360
x = 60
