B. 673,210,000
C. 67,321,000
D. 6,732,100

Answers

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).

A kayaker traveled 4 5/6 miles during the first hour, and 1 1/3 miles more then the next hour. How far did he travel in 2 hours

Answers

Answer:

11 miles

Step-by-step explanation:

Given that :

Distance traveled in first hour = 4 5/6 miles

Distance traveled in the next hour = 4 5/6 + 1 1/3

Therefore, the total distance traveled in 2 hours equals :

4 5/6 miles + (4 5/6 miles + 1 1/3 miles)

29/6 + 29/6 + 4/3

Segment AB, with endpoints A(-6,9) and B(12, -3), is dilated by a scale factor of 2/3 centered at the origin.

What are the coordinates of A'?

Enter your answer as an ordered pair, using parentheses and a comma, like this: (42,53) ​

Answers

The coordinates of A' after the dilation is (-4,6)

How to determine the coordinates of A'?

The given parameters are:

A = (-6,9)

B = (12, -3)

Scale factor, k = 2/3

The coordinates of A' is then calculated as:

A' = A * k

This gives

A' = (-6,9) * 2/3

Evaluate the product

A' = (-4,6)

Hence, the coordinates of A' after the dilation is (-4,6)

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

Answers

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

GI~JL (because corresponding parts of similar triangles are similar)

so GI/JL=ratio of similitude=7/33

GH~JK (corresponding parts of similar triangles are similar)

Answers

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

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.
