Step-by-step explanation:
The price of bronze has increased by 10% per year from 2000. In the year 2000, Harry bought a bronze medal for $120. Which of the following equations can be used to represent the price of the medal x years after 2000?
y = 120(0.9)x
y = 10(120)x
y = 120(1.1)x
y = 10(1.1)x

Answer:
A
Step-by-step explanation:
Volume of cylinder= πr²h, where r is the radius
Volume of concrete
= volume of large cylinder -volume of smaller hollow cylinder
Large cylinder:
Diameter= 7m
Since radius= ½(diameter),
Radius= 7 ÷2= 3.5m
Height= 3m
Volume of large cylinder
= π(3.5)²(3)
= 36.75π m³
Small hollow cylinder:
Diameter= 4m
Radius= 4 ÷2= 2m
Height= 3m
Volume of small hollow cylinder
= π(2)²(3)
= 12π m³
Substitute vol. of large and small hollow cylinder with 36.75π and 12π respectively, then substitute 22/7 for π:
Volume of concrete
= 36.75π -12π
= 24.75π
[tex] = 24.75( \frac{22}{7} ) \\ = 77.79 \: m^{3} [/tex]

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?
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
3.2(5+B)=5B
16+3.5B=5B
16=5B-3.5B
16=2.5B
B=16/2.5
B=26.4

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

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:
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.
Which number is larger than 1.1213 × 10^10
A. 5,445,127,000
B. 1.1217 x 10
C. 560,123,800
D. 2.468 × 10
Answer:
1.1217 x 10^10
Step-by-step explanation:
Since the question is Which number is larger than 1.1213 × 10^10 1.1217 x 10^10
is a number larger then 1.1213 × 10^10 because it has the same exponent as the problem in the question but 1.1217 has .0004 more then the problem in the question.

7x - 6 = 3 + x - 5 - 2x
Answer:
x=1/2
Step-by-step explanation:
7x−6=3+x−5−2x
Step 1: Simplify both sides of the equation.
7x−6=3+x−5−2x
7x+−6=3+x+−5+−2x
7x−6=(x+−2x)+(3+−5)(Combine Like Terms)
7x−6=−x+−2
7x−6=−x−2
Step 2: Add x to both sides.
7x−6+x=−x−2+x
8x−6=−2
Step 3: Add 6 to both sides.
8x−6+6=−2+6
8x=4
Step 4: Divide both sides by 8.
8x /8 = 4 /8
x= 1 /2

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
