Answer:
$1.5
Step-by-step explanation:
Given:
p = 1.5l
Where,
P = price p of a piece of nylon rope ( in dollars )
l = number of meters (long)
1.5 = cost of the nylon rope per dollar
How much does the nylon rope cost?
The nylon rope cost $1.5
For instance,
If l = 4 meters, price of the nylon rope is?
p = 1.5l
= 1.5(4)
= 6
P = $6
My techer said this would probably be hard for me to answer so i want to prove her wrong i tried putting this into a calculator but it would not work 10(10100) x 27
Answer:
2727000
Step-by-step explanation:
You can calculate it orally.
If numbers are multiplied with 10 we get the same answer as the number but with a zero added at the end . For example 27*10= 270
But if we divide the number ending with a zero with a ten the answer is the same but the zero is removed e.g 1000/10= 100
Similarly you have the numbers
10(10100)*27=
Now breaking the bracket part
10 (1010) 10 *27
100 ( 101)10 *27
1000(2727)
=2727000

Answer:
these are triangle problems, they are difficult unless you keep in mind that there is an invisible triangle and you use the Mnemonic SOH CAH TOA to keep sin, cos, and tan, straight..
Step-by-step explanation:
what do we know about the imaginary triangle that is being made from Susan to the lighthouse? that from Susan's feet to the lighthouse base is 200 m so that side of the imaginary triangle is 200 meters.. got it... Susan's eyes are 1.22 meters up and that her angle of looking up at the top of the lighthouse is 9 degrees.. okay .. we have enough info to solve this. B/c we have an angle and also the adjacent ( next to ) side to that angle , great
B/c we have the adjacent side and the angle.. and we want to know the Opposite side.. which will be the height of the light house, use one of the SOH CAH TOA formulas for those three pieces of info in it.. I see that that TOA has all of those. Tan(Ф)= Opp / Adj
Tan(Ф) is our angle
Opp is the Opposite side that we want to find
Adj is the Adjacent side that we know.. 200
Tan(9)=Opp / 200
use algebra to rearrange our formula
Tan(Ф)*Adj = Opp
Tan(9)*200 = Opp
I'll use my calculator to figure out what tan(9) is b/c I don't have that memorized :P and multiply that by 200
31.677 m
Also.. b/c we just figured out the triangle from Susan's eyes to the lighthouse.. we have to add her eye height off the ground to our answer
31.677+1.22= 32.897
yeah 32.9 looks like the right answer
2(2x+2)=16
Distributive property
Answer:
x=3
Step-by-step explanation:
you distribute then solve
Answer:
x = 3
Step-by-step explanation:
To solve for x, we need to distribute the 2 into the values in the paranthesis by multiplying both values within the paranthesis by the value outside the paranthesis. Doing so, we get 4x + 4 = 16
4x = 12
x =3
Two blueberry farms are similar in shape. The ratio of the side lengths of the farms is 4:5, and the smaller farm has a perimeter of 360 yards. The cost to dig a trench is $0.75 per yard. What is the cost to dig a bench around the larger blueberry farm?
Answer:
$337.50
Step-by-step explanation:
Firstly, we need to get the perimeter of the larger farm.
Since the ratio of the sides of the smaller to
the larger is 4:5, then this will be the ratio of their perimeter too
4/5 = 360/x
4x = 5 * 360
x = (5 * 360)/4
x = 450 yards
Now the cost to dig is $0.75 per yard
For a perimeter of 450, the cost will be 450 * $0.75 = $337.5

The interquartile range of the data set is 4. 2, 2, 3, 3, 4, 5, 5, 6, 7, 9, 12 Which explains whether or not 12 is an outlier? Twelve is an outlier because it is greater than the sum of 7 and 4. Twelve is an outlier because it is less than the sum of 7 and 6. Twelve is not an outlier because it is greater than the sum of 7 and 4. Twelve is not an outlier because it is less than the sum of 7 and 6.
Answer:
An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. ... Examination of the data for unusual observations that are far removed from the mass of data. These points are often referred to as outliers. Which explains whether or not 12 is an outlier? Twelve is not an outlier because it is less than the sum of 7 and 6.
Step-by-step explanation:
In the given dataset, twelve is not an outlier because it is less than the sum of 7 and 6.
The outlier of a dataset is the date that are distant from other values of the dataset.
Given that:
[tex]S = \{ 2, 2, 3, 3, 4, 5, 5, 6, 7, 9, 12\}[/tex] --- the dataset
[tex]N = 11[/tex] -- number of observations
[tex]IQR = 4[/tex]
The position of the lower quartile of the above set is:
[tex]Q_1 = \frac{1}{4} \times (N + 1)th[/tex]
[tex]Q_1 = \frac{1}{4} \times (11 + 1)th[/tex]
[tex]Q_1 = \frac{1}{4} \times (12)th[/tex]
[tex]Q_1 = 3rd[/tex]
The 3rd element is 3. So:
[tex]Q_1 = 3[/tex]
Similarly, the position of the upper quartile of the above set is:
[tex]Q_3 = \frac{3}{4} \times (N + 1)th[/tex]
[tex]Q_3 = \frac{3}{4} \times (11 + 1)th[/tex]
[tex]Q_3 = \frac{3}{4} \times (12)th[/tex]
[tex]Q_3 = 9th[/tex]
The 9th element is 7. So:
[tex]Q_3 = 7[/tex]
The lower outlier (L) is
[tex]L = Q_1 - (1.5 \times IQR)[/tex]
[tex]L = 3 - (1.5 \times 4)[/tex]
[tex]L = 3 - 6[/tex]
[tex]L = - 3[/tex]
The upper outlier (U) is:
[tex]U = Q_1 + (1.5 \times IQR)[/tex]
[tex]U = 7 + (1.5 \times 4)[/tex]
[tex]U = 7 + 6[/tex]
[tex]U= 13[/tex]
Values from the lower to the upper outliers are not outliers.
In other words
[tex]-3, -2, -1, 0, 1, 2,......,11,12,13[/tex] are not outliers
12 is not an outlier because it is less than 13
13 is gotten from 7 + 6; as in: [tex]U = 7 + 6[/tex]
Hence, (d) is correct

Carnival M charges an entrance fee of $7.00 and $0.85 per tocket for the rides. Carnival P charges an entrance fee of $12.00 and $0.35 per ticket for the rides. How many tickets must be purchased in order for the total cost at carnival M and carnival P to be the same?
Answer:
10 tickets must be purchased in order for the total cost at carnival M and carnival P to be the same
Step-by-step explanation:
Let the number of tickets be represented by t
Carnival M charges an entrance fee of $7.00 and $0.85 per tkcket for the rides.
$7.00 + $0.85 × t
= 7.00 + 0.85t
Carnival P charges an entrance fee of $12.00 and $0.35 per ticket for the rides.
= $12.00 + $0.35 × t
= 12.00 + 0.35t
How many tickets must be purchased in order for the total cost at carnival M and carnival P to be the same?
Carnival M = Carnival P
7.00 + 0.85t = 12.00 + 0.35t
Collect like terms
= 0.85t - 0.35t = 12.00 - 7.00
= 0.50t = 5
t = 5/0.5
t = 10 tickets.
Therefore, 10 tickets must be purchased in order for the total cost at carnival M and carnival P to be the same.

A bank employee notices an abandoned checking account with a balance of $343. The bank charges an $7 monthly fee for the account. Write the equation that gives the balance F(x) in dollars as a function of the number of months x. (use F(x) in your answer)
Answer:
F(x)=343-7xStep-by-step explanation:
let F(x) be the total amount on the account
and let x be the number of monthly charges
given that
c=$343
the monthly charge is =$7
The expression for the situation is
F(x)=c-mx
F(x)=343-7x
Therefore the expression for the balance is F(x)=343-7x

Three friends go apple picking they pick 13 apples on Saturday 14 Appleton funding they share the apples equally how many apples does each person get.
Answer:
9 apples.
Step-by-step explanation:
The first step is to sum up the apples picked by the three friends on Saturday and Sunday.
Sum of apples picked = Saturday 13 apples + Sunday 14
= 26 apples.
The next step is to divide the above sum by the number of friends that went apple picking inoder to arrive at apples picked by each.
Number gotten by each person = 27 / 3
= 9
It therefore means that each person get 3 apples a piece.

Answer:
Bo =6.4 hours
Step-by-step explanation:
"Jo and Bo are opening a fast food chain called Jobangles. Now together they can make a day's worth of fries in 3.2 hours. If it takes Jo 5 hours to make a day's worth of fries alone, then how long will it take Bo to make a day's worth of fries alone?"
we want to find Bo's hourly rate given the combined work rate for the both of them
given that both combined rate= 3.2hours
Jo takes 5 hours
the expression for combined work rate is
let Jo be J
and Bo be B
1/J+1/B=1/T
J+B/JB=1/3.2
5+B/JB=1/3.2
cross multiply we have

Answer:
C) 0.375
Step-by-step explanation:
Ok, so the question is to write 3/8 as a decimal. To turn a fraction into a decimal, you divide the numerator by the denominator.
3 ÷ 8 = 0.375
You can check your work by seeing if 0.375 as a fraction simplifies to 3/8
0.375 = 375/1000
Divide 375 and 1000 by 125 to get your simplified fraction, 3/8.
