Answer:
There are 1,679,616 ways to answer the test
Step-by-step explanation:
Here, we want to get the number of ways to answer the test
From the question, we have that there are 8 questions, with each having 6 possible answers
Hence, the total number of answers to pick from is 8 * 6 = 48
We are to pick 6 out of this total 48, with 1 option per question
So in the first, we are picking 1 out of 6
The number of ways here is;
6 C 1 = 6 ways
The next, we have 6 ways also , up to the 8th question
So, the total number of ways will be;
6 * 6 * 6 * 6 * 6 * 6 * 6 * 6 = 6^8 =
1,679,616

Use π = 3.14, and round your answer to the nearest hundredth
Answers
Answer:
3.13
Step-by-step explanation:
Because the 4 is in the hundreds place. The rule for the number would be less than five so round down. 4-1=3.
The value of π to the nearest hundredth is 3.14.
What is a place value?Place value, which is related to a digit's location in a number, is the amount that each digit is worth.
Given:
An equation,
π = 3.14
To round off the number to the nearest hundredth:
The digit at the hundredth place in decimal is 4.
And the left to the digit is 3.
The number 4 is less than the number 5.
So, there will be no changes in the approximation of the decimal number.
So, π = 3.14.
Therefore, the value is π = 3.14.

The number of dollars in Chi's bank account on Tuesday was 4 times as much as the amount on Friday. How many dollars were in the account on Friday?
Answers
Answer:
Step-by-step explanation:
Since we are not given actual numerical values then we can use the available information to write an equation that calculates the final amount in the account on Friday (f). In this equation, x will be our variable that represents the amount of money in the account on Tuesday. Since the amount on Tuesday was 4 times more than on Friday, we need to divide the amount on Tuesday by 4 to get the amount on Friday.
f = [tex]\frac{x}{4}[/tex]
This equation will give us the value of the account on Friday after we input the value of x.

What is the value of x in the equation ln (x + 6) – ln (2x – 1) = 0?

Answer:
x = 7
Step-by-step explanation:
(7 + 6) - (14 - 1) = 13 - 13 = 0
Answer:
x = 7
Step-by-step explanation:
Using the rules of logarithms
log x - log y = log ([tex]\frac{x}{y}[/tex] )
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]
Given
ln(x + 6) - ln(2x - 1) = 0
ln ([tex]\frac{x+6}{2x-1}[/tex] ) = 0
[tex]\frac{x+6}{2x-1}[/tex] = [tex]e^{0}[/tex] = 1 , then
2x - 1 = x + 6 ( subtract x from both sides )
x - 1 = 6 ( add 1 to both sides )
x = 7

9/7 = 117/x solve for x
across multiply 9 with x and 7 with 117
9 x (x) = 9x
7 x 117 = 819
then you get 9x = 819 and you divide that
9x = 819
÷ 9 ÷9
the you get your x
x = 91
then add your original 117 and 91 to get 208
117 + 91 = 208

9. The plane would travel about 93.3 miles in 20 minutes.
EXPLANATION:
We know that the plane goes 280 miles per hour. And we only want one third of that hour (20 minutes). So you would just divide 280 by 3.
60 minutes (1 hour) = 280 miles
÷ 3. ÷ 3 divide by 3
20 minutes ≈ 93 miles

A = 2·(0.5·7+4·7+4·0.5) fill in the blanks

11. 174 mm
EXPLANATION:
First find the missing lengths. To find height of the bottom rectangle you would just do 15-9 which equals 6, and for the width you would add 14 + 6 which equals 20.
15mm - 9mm = 6mm
14mm + 6mm = 20mm
After you have all of your sides, you can do separate the rectangles to do the area formula. A = (L)(W)
A = (15mm)(6mm) which equals 90mm
A = (14mm)(6mm) which equals 84mm
Next you add the two sums together, and you have your area!
90mm + 84mm = 174mm
A= 174mm

4400 dollars is placed in an account with an annual interest rate of 7%. To the nearest year, how long will it take for the account value to reach 10100 dollars?
Answers
Answer:
19 years approx
Step-by-step explanation:
Given data
Principal P= $4400
Rate r=7%
Final amount A=$10100
Time t= ???
Let us apply the simple interest expression
A=P(1+rt)
substitute
10100=4400(1+0.07*t)
open bracket
10100=4400+308t
10100-4400=308t
5700=308t
t= 5700/308
t= 18.50
Hence the time is 19 years approx

The formula shows that c, the total cost of buying pizzas at Al's restaurant depends on p, the number of pizzas ordered.
c=9p
What is the independent variable in the equation?
Answers
Answer:
p, the number of pizzas ordered
Step-by-step explanation:
The independent variable in the equation will be the variable that controls the cost.
Since the total cost will depend on the number of pizzas ordered, the number of pizzas ordered will be the independent variable.
The total cost is the dependent variable, since it depends on the number of pizzas.
So, the independent variable in the equation is p, the number of pizzas ordered.

Write the equation of a circle with center (0,−6) and radius 4 in general form.
Answers
Answer:
x^2 + (y + 6)^2 = 4^2
Step-by-step explanation:
The general form we need here is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.
If the center is at (0, -6) and the radius is 4, then the desired equation is
(x - 0)^2 + (y + 6)^2 = 4^2, or just
x^2 + (y + 6)^2 = 4^2
AABC is dilated by a factor of 4 to produce AA'B'C'.
What is A'C, the length of AC after the dilation? What is the measure of ZA?
Answers
Answer:
A
Step-by-step explanation:
because the sky is blue
The length of AC after dilation will be 20. Then the measure of the angle ∠A' will be 37°.
We have given that,
AABC is dilated by a factor of 4 to produce AA'B'C'.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
The triangle ΔABC is dilated by a factor of 4 to produce the triangle ΔA'B'C'.
Then the length of AC after dilation. We have
A'C' = scale factor x AC
A'C' = 4 x 5
A'C' = 20
Then the measure of the angle ∠A' will be
There is no effect of dilation on the angle.
∠A = ∠A' = 37°
Thus, the correct option is A.
