Christina loses 2 1/2 pounds every month for a year. How much weight did she lose that year? There are 12 months in a year. Simplify (or reduce) your answer, if necessary.
Answer:
30 pounds
Step-by-step explanation:
So for this problem you do 2 1/2 * 12, or 5/2 * 12. You get 60/2 = 30.
Answer:
30 pounds
Step-by-step explanation:
We start by converting 2 1/2 pounds into its decimal form: 2.5 pounds.
Now we consider that there are 12months per year, therefore in one year she will lose:
2.5 * 12 = 30 pounds

Daniel and Hector both throw shot put for their school's track and field team.
They each threw 5 times and recorded their distances to the nearest foot.
Daniel's Shot Put Throws (feet)
27, 30, 34, 35, 34
Hector's Shot Put Throws (feet)
38, 24, 38, 40, 35
Who has the greater mean, and by how much?
А Daniel by 3 feet
B Hector by 3 feet
С Daniel by 6 feet
D Hector by 6 feet
Answer:
Option B : Hector by 3 feet is the correct answer.
Step-by-step explanation:
Given that:
Mean of Daniel = [tex]\frac{Sum\ of\ quantities}{Number\ of\ quantities}[/tex]
Mean of Daniel = [tex]\frac{27+30+34+35+34}{5} = \frac{160}{5}[/tex]
Mean of Daniel = 32 feet
Mean of Hector = [tex]\frac{38+24+38+40+35}{5} = \frac{175}{5}[/tex]
Mean of Hector = 35 feet
Therefore,
Hector has a greater mean
Difference = Hector's Mean - Daniel's Mean
Difference = 35 - 32
Difference = 3 feet
Hence,
Option B : Hector by 3 feet is the correct answer.
How much would you need to deposit in an account now in order to have $2000 in the account in 10 years!
Assume the account earns 7% interest compounded monthly
Answer:
$2000
Step-by-step explanation:
they gotta take the first bunch then the next
find the compound interest when principal =2000 rate =20%per annum and time 3 years
⇒[tex] A = P (1 + \dfrac{R}{100} )^{n}[/tex]
=[tex]2000 (1 + \dfrac{20}{100})^{3}[/tex]
= [tex]2000 ( 1 + \dfrac{1}{5} )^{3}[/tex]
= [tex]2000 (\dfrac{6}{5}) ^{3}[/tex]
= [tex]2000 \times\dfrac{6}{5} \times \dfrac{6}{5} \times \dfrac{6}{5}[/tex]
= 16 × 6 × 6 × 6
⇒A = Rs.3456
⇒CI = A - P
⇒CI = 3456 - 2000
⇒CI = Rs.1456

Answer:
2/9
Step-by-step explanation:
each city has a probability of 1/9
one city 'or' another means to add their probabilities: 1/9 + 1/9 = 2/9
The probability of Cleveland or Dallas getting picked is [tex]\frac{2}{9}[/tex].
What is probability?'Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.'
According to the given problem,
Total number of city names = 9
Favorable events = 2 [ Cleveland, Dallas]
Probability = [tex]\frac{Favorable events}{Total number of events}[/tex]
Probability of Cleveland getting picked = [tex]\frac{1}{9}[/tex]
Probability of Dallas getting picked = [tex]\frac{1}{9}[/tex]
Probability of Cleveland OR Dallas getting picked = [tex]\frac{1}{9}+\frac{1}{9}[/tex]
= [tex]\frac{2}{9}[/tex]
Hence, we can conclude, probability of Cleveland or Dallas getting picked is [tex]\frac{2}{9}[/tex].

two numbers are 37 and 20
Step-by-step explanation:
x+y=57
let x be the smaller number
y=x+17
x + x+17=57
2x=57-17

find the area and perimeter of a 30-gon with a radius of 1
Answer:
Here :D
Step-by-step explanation:
look at one of the 30 central triangles.
Each will be isosceles with a vertex angle of 12°
base^2 = 1^2 + 1^2 - 2(1)(1)cos12°
= 2 - 2cos12°
so the perimeter is 30(2 - 2cos12°)
= 60 - 60cos12°

50, 20, 8, ...
Find the 8th term.
Answer:
0.08192
Step-by-step explanation:
Given 50, 20, 8, ...
The sequence is geometric in nature
The nth term of the geometric sequence is exoressed as;
Tn = ar^{n-1}
a is the first term = 50
r is the common ratio = 20/50 = 8/20 = 2/5
n is the number of term = 8 (since we need the 8th term)
Substitute
T8 = 50(2/5)^{8-1}
T8 = 50(2/5)^7
T8 = 50(128/78,125)
T8 = 0.08192
Hence the 8th term is 0.08192

Step-by-step explanation:
A proportional relationship is described by ...
y = kx
The value of k can be found by dividing by x:
k = y/x
For the given non-zero point (1/4, 3/8), the value of k is found to be ...

Two trains, Train A and Train B, weigh a total of 489 tons. Train A is heavier than Train B. The difference of their weights is 419 tons. What is the weight of each train
Answer:
Weight of Train A = 454 tons
Weight of Train B = 35 tons
Step-by-step explanation:
It is given that:
Let,
A represent weight of Train A
B represent weight of Train B
According to given information:
A + B = 489 Eqn 1
A - B = 419 Eqn 2
Adding Eqn 1 and 2
A + B + A - B = 489 + 419
2A = 908
Dividing both sides by 2
[tex]\frac{2A}{2}=\frac{908}{2}\\A = 454[/tex]
Putting A = 454 in Eqn 1
454 + B = 489
B = 489 - 454
B = 35
Therefore,
Weight of Train A = 454 tons
Weight of Train B = 35 tons
