Find the area of the shaded region. Round your answer to the nearest hundredth.
Answer: 1696.46
Step-by-step explanation:
6 x 6 x 3.14 = 113.1
24 x 24 x 3.14 = 1809.56
113.1 - 1809.56
thus we have 1696.46

Nathan buys a blender with a listed price of $65. Nathan uses a coupon that provides 20% off. What is the total final price Nathan pays?
Answer:
$52
Step-by-step explanation:
Given data
Price of blender= $65
Coupon = 20%
Let us find the amount of the coupon
=20/100*65
=0.2*65
=$13
Hence the amount of the coupon is $13
The total price Nathan pays is
=65-13
=$52
A sampling method where you determine randomly where you want to start selecting in the sampling frame and then follow a rule to select every xth element in the sampling frame list is called a ____ method.
Answer:
Systematic
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
Every xth element, so systematic.

Answer:
X²=(24)²+(7)²
x²=576+49
x²=625
×=25
Answer:
25
Step-by-step explanation:
Use the Pythagorean Theorem: a²+b²=c²
a=24
b=7
c=x
Plug in the numbers
(24)²+(7)²=x²
Square 24 and 7
576+49=x²
Add 576 and 49
625=x²
Take the square root on both sides
x=√625
Simplify
x=25

A bookstore costs $90 a day to keep open, and it spends $12 for each book that it sells. If each book sells for $18, what is the break-even point for this bookstore?
A. n = 12
B. n = 18
C. n = 15
D. n = 16
Answer:
Total Cost in a day is . Profit function is . And the revenue function is . In a day, bookstore must sell at least 15 books, because of 6n-90=0, in order to make profit.
Step-by-step explanation:
-90
The break-even point for this bookstore is 15, i.e. correct answer is,
C. n = 15.
Here, we have,
given that,
A bookstore costs $90 a day to keep open,
and it spends $12 for each book that it sells.
If each book sells for $18,
now, we know that,
Breakeven quantity = fixed cost / price – variable cost per unit
now, we have,
$90 / (18 - 12)
=$90 / $6
= 15
so, n = 15
Hence, The break-even point for this bookstore is 15, i.e. correct answer is, C. n = 15.

Which represents the equation of the line that
passes through the points (5,-2) and (15, 6)?
Answer:
[tex]y =\frac{4}{5}x-6[/tex]
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: [tex]y =mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
1) Determine the slope (m)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (5,-2) and (15, 6)
[tex]=\frac{6-(-2)}{15-5}\\=\frac{6+2}{15-5}\\=\frac{8}{10}\\=\frac{4}{5}[/tex]
Therefore, the slope of the line is [tex]\frac{4}{5}[/tex]. Plug this into [tex]y =mx+b[/tex]:
[tex]y =\frac{4}{5}x+b[/tex]
2) Determine the y-intercept (b)
[tex]y =\frac{4}{5}x+b[/tex]
Plug in one of the given points and solve for b
[tex]6=\frac{4}{5}(15)+b\\6=12+b[/tex]
Subtract 12 from both sides of the equation to isolate b
[tex]6-12=12+b-12\\-6=b[/tex]
Therefore, the y-intercept of the line is -6. Plug this back into [tex]y =\frac{4}{5}x+b[/tex]:
[tex]y =\frac{4}{5}x-6[/tex]

9. For each scenario, would you gather data by using a survey, an experiment, or an observational study? Why?
A) You want to know if playing certain types of music affects the way plants grow.
B) You want to know what kind of plants people prefer to grow in your town.
C) You want to know if using a certain kind of fertilizer will help the dying tree in your yard.
PLEASE PLEASE EXPLAIN WHY
Answer:
A) experiment B) Survey C) observational study
Step-by-step explanation:
A could either be experiment or observation but you are experimenting with different types of music and plants so experiment makes more sense to me.
B is a survey because you are asking a group about a topic and recording the answer which is essentially a survey.
C is an observation because you are checking to see improvement, no improvement, or stays the same ie: meaning you have to observe what happens before and after

Answer:
Addition: -1 + -3 = -4
Subtraction: (-4) - 5 = -10
Step-by-step explanation:
Since adding a positive makes a negative number stay negative, it equals -4.
Then by subtracting a negative with a positive (5), the number stays negative once again, which then equals -10.
solve this please i just need the top answer thx lol :)
Answer: x+(x+1)+(x+2) = 63
This is because x is the smallest number, so x+1 is the next value up, and x+2 is the value after that. The parenthesis are optional. I used them to separate out the three expressions. We can simplify the left side to 3x+3, which means that equation in bold is the same as 3x+3 = 63. So there are few ways we can form the equation.
You have the correct answers for the other boxes:
20+21+22 = 63
Nice work.
20, 21, 22
Step-by-step explanation:
Let x = the smallest integer of the three consecutive ones
(x + 1) = the next consecutive integer after x
(x + 2) = the next consecutive integer after (x + 1)
The sum of these three should add up to 63 so
x + (x + 1) + (x + 2) = 63
This simplifies to
3x + 3 = 63
Solving for x, we get
x = 20
Therefore, the three consecutive integers whose sum add up to 63 are 20, 21 and 22.
Jillian and Sammi sell 3 pillows for $3.20 each. Then they share the money equally. How much money does each girl get?
Answer:
$4.8
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Price of each pillow = $3.20
Total number of pillows = 3
So, total amount after selling = Price of each pillow × Total number of pillows
= $3.20 × 3
= $9.60
Total number of girls = 2
So, Money each girl gets = total amount after selling ÷ Total number of girls
= $9.60 ÷ 2
= $4.8

A sample of a radioactive isotope had an initial mass of 690 mg in the
year 1997 and decays exponentially over time. A measurement in the
year 2001 found that the sample's mass had decayed to 390 mg. What
would be the expected mass of the sample in the year 2011, to the
nearest whole number?
Answer:
its 94 on deltamath just did it
Step-by-step explanation:
Let t=0 represent the year 1997
Starting Value: 690
Write function:
y=690(b)^t
Now find the b-value:
y=390 when t=4 (2001−1997)
390=690(b)^4
390/690=690(b)^4/690
0.56521739=b^4
(0.56521739)^1/4=(b^4)^1/4
0.86706944=b
Write Complete Function:
y=690(0.86706944)^t
Find value in 2011 (use t=14):
y=690(0.86706944)^14
y=93.67062063
y≈94
