What is the standard form of the nymber 6.7321 * 108?
A. 6,732,100,000
B. 673,210,000
C. 67,321,000
D. 6,732,100
Answer:
673,210,000
Step-by-step explanation:
The given number is :
N = 6.7321 × 10⁸
We need to write it into the standard form.
10⁸ = 100000000
It can be calculated as follows :
6.7321 × 100000000 = [tex]\dfrac{67321 }{10000}\times 100000000[/tex]
= 673,210,000
So, the standard form of the given number is 673,210,000. Hence, the correct option is (c).
is 10x-5=8x-2x + 7 -2 equivalent?
Answer:
2.5
Step-by-step explanation:
Lets simpify one side first
8x - 2x + 7 +2
8-2 = 6
so 6x
7-2 = 5
6x+9
10x - 5 = 6x +5
(You add 5 due to it being negative on the other side)
+5 +5
10x= 6x +10
-6x -6x
4x = 10
Divide each side by 4
x = 2.5 or 10/4 or 5/2
Answer: No
Step-by-step explanation: To find whether these are equivalent, we first need to simplify the equation on the right.
8x-2x+7-2
8x-2x+5 (work- 7-2 = 5)
6x+5 (work- 8x-2x=6x) These are like terms, so we can subtract them
now that we have simplified, let's write the equations once again.
10x-5=6x+5
they are surely not equivalent

The researcher randomly selected 300 people, divided into subject groups by age. Over the course of a year, all the subjects regularly used the hand sanitizer. At the end of the year, the researcher compared the number of days that the subjects in each group were sick.
Which statements about this experiment are true?
Answer:
The study uses blocking and random sampling.
Step-by-step explanation:
The statement with respect to the experiment should be true is that The study uses blocking and random sampling.

Answer:
The sum of reciprocals is 2/3.
You don't need complex numbers to solve this, but if you try to find a and b you will need complex numbers.
Step-by-step explanation:
a+b = 2
a*b = 3
1/a + 1/b = x
(a*b)*(1/a + 1/b) = (a*b)x
b + a = (a*b)(x)
2 = 3x
x = 2/3
b = 2 - a
a*(2 - a) = 3
-a^2 + 2a = 3
-a^2 + 2a - 3 = 0
a^2 - 2a + 3 = 0
let's solve the quadratic equation
a^2 - 2a + 3 = a^2 - 2a + 1 + 2 = (a - 1)^2 + 2 = 0
(a - 1)^2 = -2
[tex]a_1 - 1 = \sqrt{2}i\\a_1 = 1+\sqrt{2}i\\\\a_2 - 1 = -\sqrt{2}i\\a_2 = 1 - \sqrt{2}i\\[/tex]
these options correspond to a and b from the original question.

= -75
I need help ty
Answer:
= − 1 4
Step-by-step explanation:
Answer:
z = - 14
Step-by-step explanation:
Solving for z using basic algebra
3(2z + 3) = -75
Step 1 distribute the 3
3 * 2z = 6z
3 * 3 = 9
now we have 6z + 9 = -75
step 2 subtract 9 from each side
9 - 9 cancels out
-75 - 9 = -84
now we have 6z = - 84
step 3 divide each side by 6
6z / 6 cancels out
-84 / 6 = -14
we're left with z = -14

The drama club sold bags of candy and cookies to raise money for the spring show. Bags of candy cost $8.00, and bags of cookies cost $2.50, and sales equaled $33.50 in total. There were 5 more bags of cookies than candy sold. Find the number of bags of candy and cookies sold by the drama club
Answer:
Number of bags of candy = 2
Number of bags of cookies = 7
Step-by-step explanation:
Let, number of bags of candy = X
So, Number of bags of cookies = X + 5
Cost of candy bag = $8
Cost of cookies bag = $2.5
Total sales = $33.50
So, Total cost of Candy Bags + Total cost of cookies bags = Total sales
= 8X + 2.5 ( X +5) = 33.50
= 8X + 2.5X + 12.5 = 33.50
= 10.5X = 33.50 - 12.5
= 10.5X = 21
X = 2
So, number of bags of candy = 2
Number of bags of cookies = 2 + 5 = 7
