Complete question :
A parachutist's speed during a free fall reaches 162 kilometers per hour. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 20 seconds of free fall? Do not round your answers.
Answer:
45 m/s ; 900 meters
Step-by-step explanation:
Given that :
Speed = 162 kilometers per hour ;
The speed in meters per second can be found by:
162 km/hr = (162 * 1000)m / (60 * 60) second
162 km/hr = 162000m / 3600 s
162 km/hr = 45 m/s
At this speed, how many meters will the parachutist fall during 20 seconds of free fall?
Speed of free fall = 45m /s
Distance in meters after 20 seconds :
(45 m/s * 20s) = 900 meters
Problem 1: Bob’s Citrus and Nursery sells cartons of citrus fruits. There are 24 oranges in each carton. They have 5,643 oranges to pack into cartons. How many cartons can they fill?
Problem 2: This year, 4,338 grapefruits have been harvested so far. Bob’s has 18 storage bins for grapefruits. If the grapefruits are distributed evenly among 18 bins, how many grapefruits are in each bin?
248 per bin.
The number of cartons that the oranges would fill in Bob’s Citrus and Nursery would be 235 cartons.
The number of grapefruits in each bin would be 241 grapefruits per bin.
How to find the number of cartons ?To find the number of cartons of oranges that would be filled, use the number of oranges that go into carton in Bob’s Citrus and Nursery and the number of oranges they have to pack. The formula would be:
= Number of oranges / Number of oranges per carton
= 5, 643 / 24
= 235 cartons
How to fin the number of grapefruits per bin ?The same logic is applied to find the number of grapefruits that would be in each bin. If each bin would have an equal number of grapefruits, the number of grapefruits per bin would be:
= Number of grapefruits / Number of bins
= 4, 338 / 18
= 241 grapefruits per bin

Answer/Step-by-step explanation:
The following steps to solve equation given by join are shown below including the property of numbers applied for each reasons:
4(2a + 3) = -3(a - 1) + 31 - 11a ----› Given
Apply the distributive property to open the parentheses
4*2a + 4*3 = -3*a -3*-1 + 31 - 11a
8a + 12 = -3a + 3 + 31 - 11a ----› Distributive property
Combine like terms together
8a + 12 = 3 + 31 -3a - 11a
8a + 12 = 34 - 14a ---› Combining like terms
Add 14a to both sides
8a + 12 + 14a = 34 - 14a + 14a
22a + 12 = 34 ----› Addition property
Subtract 12 from both sides
22a + 12 - 12 = 34 - 12
22a = 22 ----› subtraction property of equality
Divide both sides by 22
22a/22 = 22/22
a = 1 ----› Division property of Equality
Find the equation of the straight line which is perpendicular to the straight line 3x+4y=12 such that perpendicular distance from the origin is equal to the perpendicular distance from (3,2) on the given line
Answer:
3y-4x = -6Step-by-step explanation:
First get the slope of the given line;
Given the equation of the line 3x+4y=12
Rewrite in standard form y = mx+c where m is the slope;
3x+4y=12
4y = -3x + 12
y = -3x/4 + 12/4
y = -3x/4 + 3
Hence the slope of the given line is -3/4
Since the required line is perpendicular to this line, the slope of the required line will be M = -1/(-3/4) = 4/3
Get the equation:
Substitute M = 4/3 and the point (3,2) into the point slope equation of a line as shown;
y-y0 = m(x-x0)
y - 2 = 4/3(x-3)
Cross multiply
3(y-2) = 4(x-3)
3y - 6 = 4x - 12
3y - 4x = -12 + 6
3y-4x = -6
Hence the required equation of the line is 3y-4x = -6
Betty is three times as old as her son now. In 12 years, Betty's age will be three years less than twice her son's age. How old is Betty's son now?
Answer:
Betty is 27. Her son is 9.
Step-by-step explanation:
We will use b to represent Betty's age. We will use s to represent her son's age.
This year:
b = 3s
In 12 years' time:
b + 12 = 2(s + 12) - 3
b + 12 = 2s + 24 - 3
b + 12 = 2s + 21
b = 2s + 9
We know that b = 3s, so we can substitute this value into our equation.
3s = 2s + 9
s = 9
b = 3 x 9
b = 27

V=42.42/3
V=14.13in³
Consider a large population with a mean of 100 and a standard deviation of 21. A random sample of size 36 is taken from this population. The standard error of the sampling distribution of sample mean.
Answer:
3.5
Step-by-step explanation:
Given that:
Population mean (m) = 100
Standard deviation (σ) = 21
Sample size (n) = 36
The standard error of the sampling distribution of sample mean :
Standard Error is given by:
Standard deviation / sqrt(n)
Thus,
Standard Error = 21 / sqrt(36)
Standard Error = 21 / 6
Standard Error = 3.5

7. You are ordering sweaters from American Eagle. Each sweater costs $25. They also charge a shipping fee of $7. You spent. $132 How many sweaters?
Answer:
Step-by-step explanation:
Alright, after reading this problem, let’s highlight some key points. Each sweater costs $25, we can write that down as 25x because will represent the amount of sweaters we buy. But we have a shipping fee of $7, so we will +7 to our highlights. And the total money spent was $132.
So far, we have: 25x + 7 = 132
Let’s subtract the 7 from the 132. Now we have: 25x = 125
Then we can divide by 25 on each side, and get x by itself.
X = 5 sweaters.
BONUS: Let’s replace 5 for our x to prove our answer
25(5) + 7 = 132 >>> 125 + 7 = 132 >>> 132 = 132 :D
There you go!! We buy 5 sweaters from American Eagle..!

A clearance rack is marked as 60% off the regular price to be taken at the register. If a jacket on the clearance rack is marked $239.99, what will it ring up for at the register
Answer:
$399.98
Step-by-step explanation:
Given
Mark down percent = 60%
Mark down price = $239.99
Required
Original price of the rack
Let x be the original price of the product. The equation to get x is as expressed below;
60% of x = 239.99
0.6x = 239.99
x = 239.99/0.6
x = 399.98
Hence the rack will ring up for $399.98 at the register
If r is the radius of a circle and d is its diameter, which of the following is an
equivalent formula for the circumference C = 2 pie r?
A. C= pie d
B. C= 2 pie d
C. C=2 pie d^2
D. C = 2 pie rd
Answer:
A
Step-by-step explanation:
because r is 1/2 of d so you would have 1 d instead of 2 r
A series is defined by 5+9+13+17+.......+805 a. Find the number of terms of the series. b. Find the sum of the first 20 terms.
Answer: the number of terms of the series is 201 numbers
the sum of the first 20 terms is 890
the number of terms of the series is [tex]\frac{805-5}{4}+1=201[/tex]
the series have:
u1 = 5
d = 4
=> u(n) = 5 + 4.(n - 1)
=> u(20) = 5 + 19.4 = 81
so the sum of the first 20 terms is (81 + 5).20/2 = 890
( u1 is the first number of the series, d is the distance between front and rear numbers, u(n) is the overall term of the sequence, u(20) is the 20th of the series)
Step-by-step explanation:
Holly begins with 1 penny in her piggy bank. She adds 2 pennies on day 1, 4 pennies on day 2, and 8 pennies on day 3. She continues this pattern for 30 days.
Which statement describes why this sequence is a function?
Select EACH correct answer.
a Each amount of pennies corresponds to a unique day in this sequence.
b The graph of this sequence would pass the horizontal line test.
c Each day corresponds to a unique amount of pennies in this sequence.
d The graph of this sequence would pass the vertical line test.
Answer:
The answer is c and b
Step-by-step explanation:
I took the test
Options B, C and D are correct.
The Graph of this sequence would pass the horizontal line test.Each day corresponds to a unique amount of pennies in this sequence.The Graph of this sequence would pass the vertical line test.We have Holly and her penny collection.
We have to select the correct alternatives from the given.
Starting from 1 marble if you add 'x' marble every day for n days, then you have a total of 40 marbles. Find n.1 + nx = 40
nx = 39
n = 39/x
According to the question-
Initial Amount in piggy bank = 1 penny.
Now -
She adds -
2 Pennies on Day 1.
4 Pennies on Day 2.
8 Pennies on Day 3.
Therefore, the following sequence represents her collection -
1, 2, 4, 8 .....
It can be seen that each day corresponds to a unique amount of pennies in this sequence.
Now -
Vertical line test → to satisfy this test the graph should not have two or more points going through a vertical line.
Horizontal Line test → to clear this test the graph should not have two or more points going through a Horizontal line.
If we plot the graph of this function - Refer to image attached. It can be seen that the graph of this sequence passes horizontal line and vertical line test.
Hence, Options B, C and D are correct.
