Answer:
Correct Choice: B) 4.7x10^1
Step-by-step explanation:
Scientific Notation
The diameter of a red blood cell is about 0.0008 cm. Expressing in scientific notation, the diameter is [tex]8\cdot 10^{-4} \ cm[/tex].
The diameter of a chickenpox virus is about [tex]1.7\cdot 10^{-5}\ cm[/tex]. It's already expressed in scientific notation.
The ratio of both measures is:
[tex]\displaystyle \frac{8\cdot 10^{-4} \ cm}{1.7\cdot 10^{-5}\ cm}[/tex]
Dividing the coefficients and subtracting the exponents:
[tex]\displaystyle 4.7\cdot 10^{1}[/tex]
Correct Choice: B) 4.7x10^1
What is the first step in solving this expression? 28 - 11 + 6 ● 3 + 5
Thanks,
Answer:
First Step of solving this expression: Multiply
Answer for the expression: 40
Step-by-step explanation:
To find the first step you need to follow the order of operation
Parenthesis
Exponents
Multiplication and Division
Addition and Subtraction
Since there are not Parenthesis or Exponents then you may skip that step but there is a multiplication sign so the first step is Multiplication
To solve multiply 6 and 3
Which is 18
Now the expression looks like this:
28-11+18+5
Now simplify from left to right:
28-11=17
17+18=35
35+5=40
Hope this helps!
Answer: Multiply 6*3, then add 18+5, then subtract 28-11, then add them:
17 + 23 = 40!

what’s 6/7 - 1/2? also how do i subtract fractions with unlike denominators? you don’t have to answer the 2nd question
6/7 - 1/2 equals 5/14.
Subtract the fractions: Now that the fractions have the same denominator, you can subtract them by subtracting the numerators while keeping the common denominator. In this case, subtracting 7/14 from 12/14 gives you 5/14.
To subtract fractions with unlike denominators, you need to find a common denominator for both fractions. The common denominator is the least common multiple (LCM) of the denominators. Once you have the common denominator, you can subtract the fractions by following these steps:
Find the LCM of the denominators: In this case, the denominators are 7 and 2. The LCM of 7 and 2 is 14.
Rewrite the fractions with the common denominator: To rewrite 6/7 and 1/2 with a common denominator of 14, you need to multiply both the numerator and denominator of each fraction by a suitable factor. For 6/7, you would multiply both numerator and denominator by 2 to get 12/14. For 1/2, you would multiply both numerator and denominator by 7 to get 7/14.
Subtract the fractions: Now that the fractions have the same denominator, you can subtract them by subtracting the numerators while keeping the common denominator. In this case, subtracting 7/14 from 12/14 gives you 5/14.
Therefore, 6/7 - 1/2 equals 5/14.

If DH = (4x + 10) in. and HI = (2x − 4) in., then x =_______ , HI =_______ , and ID = _________
Answer:
x = ∞ infinite solutions or 0
HI = infinite solutions
ID = infinite solutions.
Step-by-step explanation:
Oh okay I got this now!
ID + HI = DH
ID + 2x - 4 = 4x + 10 (subtract 2x on both sides)
ID - 4 = 2x + 10 (add 4 on both sides)
ID = 2x + 14
So now ID + HI = DH
2x + 14 + 2x - 4 = 4x + 10 (simplify)
4x + 10 = 4x + 10 (subtract 10 on both sides)
4x = 4x (minus 4x on both sides)
0 = 0
I would plug in 0 as x.

determine the x value for the vertex and whether this value is a maximum or a minimum
a. maximum at x = -1.25
b. maximum at x = 1.25
c. minimum at x = -1.25
d. minimum at x = 1.25
Answer: D
Explanation:
Use the vertex formula, -b/2a. Because the quadratic formula is ax^2+bx+c, -b would be 5 in this case and a would be 2 in this case. Plug the numbers in and you get 5/4. The AOS or vertex would be 5/4 or 1.25. Because the a-value is a positive in this equation, the parabola would have a minimum.
Joe can run 12 miles in 125 minutes. How many miles can he run in 230 minutes? (solve and explain the steps)
Answer:
Joe will run 22.08 miles in 230 minutes.
Step-by-step explanation:
Given that Joe can run 12 miles in 125 minutes.so Joe running the miles in 1 minute is = 12/125 = 0.096 miles
unit rate = 0.096 miles/per minuteAs Joe runs 0.096 miles in one minute.
Thus, in 230 minutes, Joe will run = 0.096 × 230 = 22.08 miles
Therefore, Joe will run 22.08 miles in 230 minutes.
